In the drawings, wherein for the purpose of illustration is shown a preferred embodiment of my invention, the numeral 20 designates the barrel of the gun, and this barrel has its rear end portion 20 exteriorly reduced in diameter and is preferably screw-threaded, as shown at'21, to engage within a screwthreaded opening formed in a transverse disk or support-member 22, which is rigidly mounted within the forward portion of the frame or receiver 23. This disk or supportmember may be rigidly attached to the re ceiver by any suitable means, andmay be brazed therein, if desired. lhe numeral 21, designates a second disk or supportmember, which is rigidly mounted in the extreme forward end of the receiver 23 and has an opening 22, to receive the reduced portion 20. This reduced portion 20 forms a shoulder 23, with the forward portion of the barrel 20, as shown. The forward end of the receiver or frame 23 is preferably contracted,

as indicated at 24, and is provided with an o enin 'for receivin the barrel 20 as is usual in gun constructions. The receiver or frame 23 has a stock 25, suitably secured to a sub-frame The numeral 26 designates the fore arm of the gun, which is preferablydetachably mounted upon the lower portion of the receiver 23, near its forward end. The barrel 20 is provided at its forward end with a sight 27, of any well known or preferred type and is also equipped with an open'rear sight 28, and a peep sight 29, at the rear end thereof, as shown. The numeral 30 designates a tube or magazine for holding the bullets, and this magazine or tube is arranged beneath the barrel 20, as shown. The forward end of this magazine is closed and is suitably attached to the barrel 20 while the rear end of the magazine extends into the contracted portion 2 1 of the receiver 23, and passes through an opening 31, formed in the disk 21, and opening 32, formed in the CIT disk 22, as more clearly shown in. Figure 3. It will be understood that this is the preferred manner of mounting the barrel and magazine within the receiver, for effecting astrong and rigid connection, but the invention is in no sense restricted to this particular type of mounting. The magazine 30 is preferably provided upon its exterior, with a longitudinal scale 29 forcoaction with a thumb piece 176, to be described, to indicate thenumber of bullets in the magazine.

The upper portion of the receiver 23 is pressible coil spring, to be described. This plunger 3'? is rigidly mounted upon a plunger rod 38, as more clearly illustrated in Figure 12. The detailed construction of the plunger will be described hereinafter. The plunger rod 38 slides within a guide sleeve or tube 39 which is carried by the cap 35, and preferably formed integral therewith. A main compressible coilspring 4O surrounds the plunger rod 38 and guide sleeve or tube 39, rearwardly of the plunger 37, as shown. This spring 40 is mounted within the air chamber, and is confined between the plunger 37 and the abutment 35 carried by the air chamber. The plunger rod 38 projects rearwardly through an opening in the cap 35 and is provided at its rear end with a sear engaging head 41, as shown.

The air chamber or cylinder 34- is adapted to move forwardly into close relation with the rear nd of the barrel 20, and this chamber or cylinder is adapted to cover and uncover a main opening 42, formed in thetop of the guide cylinder 33. The opening 42, affords access to the rear of the bore 43 of the barrel, whereby the bullets may be manually introduced into this bore, when de-' sired. The bore 43 is uniform in diameter throughout its entire length. i i

The construction of the forward end of the air chamber or cylinder 34 will now be given, and for this purpose, attention is called particularly to Figures 2 and 12. The air-chamber 34 is provided with a forward end or head 44, preferably formed integral therewith. This head is provided with a rearwardly extending tubular socket 45, integral therewith. The socket 45 is adapted to receive a tubular nipple or reduced eX- tension 46, formed upon the extreme end of the barrel 20. These parts have a closesliding fit. The numeral 47 designates a packing element or washer, which is preferably formed of fiber of medium. hardness, but possessing a suitable yielding action. This packing element has an opening through which the tubular extension 46 projects, and the packing element is arranged rearwardly of the disk or support-member 22. The bore 43 of the b-arrelerztends through the reduced extension 46, and is in communication with a bore 43, which passes through the socket 45, and associated shock absorbing elements, to be described. Particular attention is however called to the fact that a joint is effected between the head 44 of the air chamber 34 and the rear end of the barrel 20, which is air tight to the maximum extent, and this joint is ffected without reducing the diameter of the bore of the barrel, or the bore 43, which is in effect a continuation of the bore of the barrel. This is important, as it provides the maximum compression of the air within the air chamber, and also ofiers the least resistance to the discharge of the air through the bore of the barrel, when the gun is being discharged.

The shock absorbing means which is arranged within the forward end of the air chamber 34, rearwardly of and adjacent to the head 44, to take the lmpact of the plunger or piston 37, embodies awrear washer 48, preferably formed of hard woor. fiber, an in termediate washer 49, preferably formed of leather, and a forward washer 50, preferably formed of felt. The washers or elements 48, 49 and 50 are held against turning movement, in the forward end of the air chamber 34 by any suitable means, or by frictional engagement therein, and the bore or opening 43 is formed through the upper portions of these washers or elements. The guide cylinder 33 and the air chamber 34, with the elements carried therein, are preferably arranged eccentric with respect to the barrel 20, and this construction is advantageous as it eliminates the necessity of employing a high front sight.

The plunger '37 embodies a cylindrical body portion 51, having a sliding fit within the air chamber 34, and this body portion has the forward end of the plunger rod 38, secured thereto, as clearly shown in Figure 12. The body portion 51 carries a rear annular flange 52, provided with annular surface grooves 53, carrying lubircating rings 54, which may be made of felt, or any other suitable material. The body poition 51 is proviriled with a forwardly extending portion which is diametrically reduced or contracted, and is adapted for the reception of the packing rings of the plunger or piston. I have found that these packing rings are of considerable importance, as I have been able to obtain the maximum compression by the use of the same, comblned with long wear, and the minimum friction. The

57 supports the split packing ring 59, preferably formed of hard fiber. Arranged forwardly of the carrier 56 is a solid packing ring 60, preferably formed of hard fiber. The several rings are retained in place upon "the reduced portion by means of a head or cap 61, secured to the portion 55 by means of a screw 62 or the like. The precise construction of the piston and its packing means is important. I provide the solid .1 packing ring 60, formed of fiber, as the same constitutes a piston guide for the plunger within the air chamber 34, and fiber will slide'within the chamber with the least friction. The split packing rings 58 and 59 are expansible and contractible within limits,

and hence are adapted to accurately contact with the inner wall of the chamber 34, for effecting the maximum compression. A cast iron packing ring would be more suitable 'for' producing the maximum compression,

but would tend to produce friction and hence retard the proper movement of the plunger. The split fiber packing ring would not produce as much compression as the cast 1 iron packing ring but less friction. I have found that lnghly advantageous results are obtainable by employing two split packin rings, one of cast iron, and one of fiber, and having their combined cross-sectional areas about equal to that of one packing ring, and

hence I obtain. a combination of the advantages of both types of packin rings, without the disadvantages of a full size ring of either material. It is of course obvious that the invention is in no sense restricted to the precise form of packing shown and described.

One of the important features of my invention is the provision of means whereby the plunger actuated spring of the gun is compressed by a rearward movement of the compression lever. This means will now be described. The compression lever is designated by the numeral 62, and this compression lever is mounted between sides 63, de-

pending from the guide cylinder 33, and integral therewith. The compression lever is pivotally supported between its ends by a pin 64, attached to the sides 63. At its rear end, the compression lever 62 is equipped with a hand loop 65, as shown. The compression lever 62 has pivotal connection at its forward end, as shown at 66, with a forwardly extending link 67, which is be more fully explained. These knuckles 69 are formedintegral with a base or lug 7 2', which is rigidly secured to the lower portion .of the air chamber 34, by any suitable means.

WVhen the compression lever .62 has its lower end swung forwardly, its upper end is swung rearwardly and the air chamber 34 slides rearwardly within the guide cylinder 33. This rearward movement of the air chamber brings the sear-engaging'head or element 41, in engagement with a self-releasing sear 72, to be next described. By the term self-releasing'seai" employed in the description and claims, I mean a sear which will be. automatically moved outwardly by the action of the spring upon the plunger, to release the plunger, if not supported or: held against suchoutward releas-. ing movement, as distinguished from the ordinary type of sear which when engaging with the plunger or an element carried thereby, locks itself in such engagement. until positively moved in one direction for releasing such locking. engagement. This sear 72 is pivoted upon a transverse pin 73, mounted in a cap 74, engaging and closing the rear end of the guide cylinder 33. This cap constitutes apart of a sub-receiver or frame and embodies forwardly extending sides 75, which are passed between the sides 63, and snugly engaging therewith. These sides carry the pin 64. These sides have open1ngs'7 6, for receiving the pin 64, which serves to. connect the forward ends of the sides 75 with the main sides 63. The numeral 77 designates a pair of bolts, Figures 1, 2, 4 and 21,.which extend transversely through openings in the sides 63 and through openings 78 in the side 75, thereby securely locking the sub-frameto the main frame or receiver. The, sear 72 is pivoted upon the pin 73, as above stated, and is provided at its free end, and above the pivot 73 with a resetting extension 79, which is adapted to be engaged by the head 41, and swung rearwardly by this head, in opposition to a plunger 80, compressing the spring 81. This plunger is slidable within a tube 82, formed in the cap 74, asmore clearly shown in Figure 2. When the resetting extension 7 9 is swung rearwardly, as above stated, the forward end of the sear is swung upwardly to the reset position, as will be described. As' more clearly shown in Figure 4, the sear 72 is provided with a substantially horizontal portion 83, and projecting forwardly in advance'of the pivot 73 and provided with an upwardly projecting holding extension 84, which is adapted to engage in advance of the sear-engaging head at the beginning of its rearward or compression stroke, for compressing the plunger actuating spring. The sear 72 embodies a relatively long forwardly projecting arm or lever 85, arranged beneath the pivot 73, and provided at its forward end with a trigger engaging foot 86. This foot has an inclined or beveled face 87, of substantial length, which is adapted to engage with an inclined face 88, of substantial length, formed upon the rear edge of a trigger 89. This trigger is mounted upon a pivot pin 90, which in turn is carried by the sides 75 of the subframe. The trigger extends downwardly beyond its pivot 90 into a finger engaging part 91, which is located within a trigger guard 92, formed in the compression lever 62. The trigger 89 has its upper end urged rearwardly by a plunger 92, slidable within a guide cylinder 93., which is arranged between the sides of the sub-frame and rigidly secured thereto by any suitable means. The plunger 92 is urged downwardly by a compressible coil spring 9i, and the plunger carries an upwardly extending rod 95, projecting above the cylinder 93. It will thus be seen that if the finger engaging portion 91 of the trigger is pulled rearwardly, the upper portion of the trigger 89 will move forwardly, and the forward end of the sear 72 will be released, whereby the sear will swing downwardly, and the head 411 will be released. This will permit of the discharge of the gun.

I provide an automatic safety device to prevent the trigger 89 being pulled for discharging the gun, until a grip releasing device has been actuated, which is instinctively effected in gripping the gun in shooting. This automatic safety device embodies a sliding stop 97-, operating between the top of the cylinder 93, and a pin 98, extending transversely above the stop and attached to the sides of the. sub-frame. The stop 97 has aninclined rear end 99, as shown. This stop 97 is provided with an arm 100, which is pivotally connected with a bell crank lever 101, pivoted upon a pin 102, attached to the sub-frame. Thebell crank lever 101 has its lower arm 103, opera-ting within the slot ted end ofa stationary guide cylinder 10 i, rigidly mounted in the sub-frame. This guide cylinder 10 1 slidably receives a reciprocatory cylinder 105, within which is mounteda recip-rocatory plunge-r 106, urged downwardly by a compressible coil spring 107. The plunger 106 contacts with the arm 103 of the bell crank lever, and normally forces this arm downwardly, whereby the stop 9'? is drawn to the right, over the rod 95, and theplunger .92 locked against upward movement, and hence the trigger cannot be pulled rearwardly.

The sliding cylinder 105 has its upper end tapered or beveled, as shown. This upper tapered end is adapted to engage with beveled faces 108 and 109, formed upon the end of a latch 1.10, pivoted at 111. The beveled face 108 is higher than the beveled face 109, and hence when the latch is in the position shown in Figure 1, the spring 107 will hold the sliding cylinder, 106 in the uppermost position. In this position, the arm 103 of the bell crank lever 101 will project downwardly beyond the lower end of the sliding sleeve 105. When the parts are so adjus ed, the grip actuated releasing meansimay be employed to operate the automatic safety device for releasing the trigger. The grip releasing means embodies a lever 112, operating within a slot formed in the lever 62, and pivoted therein zit-113. The lever 112 has its forward end swung upwardly by means of a spring 114:. This lever is provided rearwardly of its pivot with a lateral extension, 115, which is of substantially the same diameter as the sliding cylinder 105, and is thereby adapted to enter the stationary cylinder 104i and force the arm 103 upwardly. It is thus seen that when the latch 110 is in the released position, as soon as the operator presses the lever 112 upwardly, the bell crank lever 101 will be swung forwa-rd 1y upon its pivot, and the stop 97 moved out of the path of travel of the rod 95, thereby permitting of the. upward movement of this rod and the pulling of the trigger.

If it should also be desired to lock the safety device against operation by thegrip releasing means, the lever 110 will have its upper arm swung upwardly, whereby the lower face 109 will be brought into engagement with the tapered end of the sliding cylinder 105, and this sliding cylinder will be lowered sufficiently whereby its lower slotted end will project downwardly so that it will either be flush with the lower edge of the arm 103, or slightly below it. If the lever 112 is now moved inwardly, its lateral extension 115 will engage the lower end of the cylinder 105, which is now positively held against upward movement, and hence this extension cannot shift the arm 1 03 upwardly. The trigger will thus remain locked until the latch 110 is shifted downwardly.

As is well known, some sportsmen prefer a very light pull of a trigger, while others prefer much harder pull, and to meet these requirements, 1 have provided means for accurately adjusting the pull on the trigger. In accordance with my invention, the trigger 89, see more particularly Figures i, 15, 16, 18, is provided upon its in nor side with a lateral extension or lug 116, having a beveled face 117, adapted to be engaged by a tapered or beveled head 11 8, carthe receiver.

ried by a bolt 119. This bolt is screwthreaded within a sleeve 120, and this sleeve is in turn screwthreaded within an opening 121, formed in one of the sides 63 of The bolt 119 is provided in its outer end with a slot 122, so that it may be turned with respect to the sleeve 120, by means of a screw driver or the like. This is toprovide a selected adjustment, at which the gun may be set, independently of the manual adjustment, to bedescribed.

The sleeve 120 carries a pointer 123, rigidly connected therewith, and extending radially therefrom, and this pointer is provlded with a button 124:, by means of which it 1 to move rearwardly a greater distance.

The inclined face 88 will now move rearwardly in engagement with the inclined face 87 of the sear, and hence the extent of contacting surfaces of these faces is increased. It should be remembered thatthe entire force of the spring 40, under compression, is transmitted to these contacting faces 87 and 88, and it will be seen that the frictional engagement between these faces will vary with the extent of the contacting areas of the faces. Furtheiythe faces 87 and 88 being inclined, as shown, the trigger must move the sear 72 upwardly a greater distance, as the engaging surfaces of the faces 87 and 88 are inclined. For these two reasons, the pull upon the trigger 89 varies, in accordance with the distance that the upper end of the trigger is permitted to travel, when engaging with the sear. It is thus seen that the desired trigger pull may be obtained, by manually adjusting the pointer 123 with respect to its scale 125, without the employment of a screw-driver, or other implement.

My gun is designed to be used as a single shot gun or as a repeater. To accomplish this, I provide means for transferring the bullets from the magazine to the rear end of the barrel. This transferring means embodies a pivot or laterally movable carrier 126. The carrier embodies a pair of sides 127, see particularly Figures 1, 5, 6 and 17. Disposed between the forward ends of these sides 127 is a casing or block 127, rigidly secured thereto. The sides 127 are provided at their rear ends with upwardly projecting knuckles-132. and each of these knuckles are pivotaily connected with the side 63,

by means of a shoulder bolt 133, which does not project inwardly beyond the knuckle. It will be understood that the knuckles 132 are arranged outwardly of the path of travel of the knuckles 69 and 70, and the lug 72. The sides 127 of the carrier are provided at the rear ends with cam extensions 13%, the upper edges of which are adapted to engage with the knuckle 69, which functions as a trip element. As clearly shown in Figure 1-, when the air chamber 34 is moved rearwardly sufiiciently, the knuckle 69 will ride over the cam extension 134 of the carrier,and swing the 1 carrier vertically within the receiver, upon its pivot, causing the forwardend of the carrier to move to its uppermost position, adjacent to the rear end of the barrel 20. When in this'uppermost position,-the forward edges or corners of the sides 127 contact with the inner wall of the guide cylinder 33 of the receiver Figure 17, and hence the carrier is positively held against movement upon its pivot, at this time, and durin the period that the ejector is being actuated for introducing the bulletinto the rear end of the barrel. The carrier is therefore positively actuated and positively held against improper movement, and the movement of the carrier, or the holding of the same, is not effected by means of springs, or other unreliable agencies. The sides 127 of the carrier are provided near their forward ends with cam edges or faces 135, which are adapted to move upwardly into the path of travel of the forward end of the air chamber 34:, when'the air chamber is in the rear or retracted position. Now, when the air chamber is being brought forwardly to have an air tight connection with the rear end of the barrel, the forward end of the air chamber riding over the cam surfaces 135, will swing the forward end of the carrier downwardly, the lower side of the air chamber finally riding upon the horizontal edges or faces 136, of the sides, which will serve to positively hold the carrier in the lowered positionywhile the air chamber is in the forward position. The sides 127 are provided with straight longitudinal slots 137, within which is slidably mounted the ends of a transverse pin 138, one end of this pin operating within a guide slot 139, formed in'a plate 140, secured to one of the sides 63. The guide 1 slot 139 embodies a rear inclined portion 141 and a forward approximately horizontal portion 142. It will be seen that as the pin 138 moves rearwardly into the inclined portion 141 of-the slot, it will aid in swinging the carrier downwardly, and as it moves forwardly'into the upper or horizontal portion 14-2 of the slot, it will aid in swinging the carrier upwardly, and in holding the same in the elevated position. The principal function of the pin-138 is to actuate the ke per and ejector elem nts supported by the carrier,-a-s will be hereinafter explained. The pin 138 is rigidly mounted upon the forward end of a link 143, which link extends rearwardly and has its rear end preferably forked for straddling a vertical projection 144, formed upon the forward end of the link 67 and pivotally connected with this vertical projection, as shown at 145. It is thussee-n that when the lever 62 is moved rearwardly for advancing the air chamber, the link 143 and itspin138 are moved forwardly, for a purpose to be described.

The casing or block 127' of the carrier, has apocket 128 for receiving the bullet 146. This socket holds therein a sleeve 147, rigidly secured to the same, and this sleeve has the forward portion of its bore spherically curved, as indicated at 148, which constitutes a seat or stop for the bullet, while the rear portion of the bore, as indicated at 14-9, is tapered and flared rearwardly. This provides a knife edge 150, which forms a combined guide and fulcrum for the ejector or plunger 151, which is also mounted within the casing 127. It might be stated at this point that theejector is adapted to be shifted forwardly beyond its casing 127 for a substantial distance, so that it will introduce the bullet well into the nipple or extension 46 of the barrel 20, so that there can be no liability of the bullet not being properly introduced into the barrel. The ejector or plunger 151 is pivotally connected, at 152, with the upper end of a vertical lever 153, whichis pivotally mounted between ts ends, as shown at 154. The lever 153 1s pivotally connected at its lower end, at 155, with a link 156, which link, as more clearly shown in Figure 6, is provided at its rear end with ahead 157. This head carries-a screw or guide element 158, sliding in one of the longitudinal slots 137. This screw simply serves as a guide means for the rear end of the link 156, to prevent it from moving laterally with respect to the carrier.

The numeral 159 designates a latch, which is arranged upon the inner side of the head 157, Figure 6, and pivot-ed thereto at 160. This latch carries a laterally projectlng pin or stud 161, which is adapted to enter a notch 162, formed in the side 127. lVhen the pin 161 is in the notch 162, the link 156 is locked against longitudinal movement with respect to the carrier. The forward end of the latch 159 is urged downwardly by means of a spring 163, which tends toforce its rear end upwardly. The latch 159 is provided witha rear cam or trip portion 164, which is adapted to project upwardly across the slot 137, in advance of the head 157. This latch is also provided with: a shoulder 165. which is adapted to extend across the slot when the forward end of the latch is elevated. With ft'his explanation in. mind,

it will be seen that when the link 143 moves rearward ly, with the rearward movement of the air chamber, that the pin 138 will travel rearward ly in the slots 137 and this pin 138 will first engage the upstanding cam element or trip 164, first turning the latch 159 upon its pivot, whereby the pin'161 is withdrawn from the notch 162. This will release the link 156 so that it may move longitudinally with respect to the carrier. The further rearward movement of the pin 138 brings the same into engagement with the rear end of the head 157 of the link, and the link will therefore be shifted rearwardly, until the guide pin 158 engages the rear end wall of the slot137. During this rearward move ment of the link 156, the lever 153 is turned upon its pivot, and, the ejector or plunger 151 is moved forwardly into the rear end of the barrel. Then the pin 138 starts on its forward movement, it engages with the shoulder 165, now arranged in its path of travel, and the pin will therefore move the link 156 forwardly, until the pin 161 reaches the notch 162, at which time the pin will enter this notch and the link will then be locked against longitudinal movement. This movement of the link 156 will move the ejector or plunger 151 rearwardly.

In order that the bullet 146 may not accidentally discharge from the recess or pocket 128, when fedtherein, by means to be described, I provide a keeper 166 which is pivoted within the casing 127 at 167. This keeper has an upwardly extending lateral tongue 168, which when elevated, is adapted to project a slight distance into the bore or the pocket or recess 128, suificiently, to positively prevent the bullet frommoving forwardly out of the pocket, until the keeper is lowered. The keeper has its forward end or hp 168 urged upwardly by means of a spring 169. The keeper is provided with a rearWa-rdlyeXtendin tail 170, provided with cam surfaces 171 and 172. The cam surface 171 normally extends upwardly and transversely across the slot 137, and hence when the pin 138 moves forwardly, it engages the cam surface 171, and forces the rear end of the keeper 166 upwardly, moving the tongue 168 downwardly. It will be thus seen that, when the carrier has its forward end lowered, so that the pocket or recess 128' is adjacent to the rear discharge end of the magazine 30, the tongue 168 of the keeper will be in the opener lowered position, thus permitting of the bullet properly entering the pocket or recess. It is also necessary to provide means to move the tongue 1 68 downwardly, out of the pocket, before the ejector or plunger 151 has moved forwardly suificiently to push the bullet 146 past the tongue. To accomplish this, I provide the lever 153 with a lateral exten- 31011 173, at its lower end, which lateral extongue 168 will be moved downwardly out of the bullets.

ofthe bore of the pocket or recess, before the bullet is moved forwardly sufficiently to contact with the tongue. Of course when the lever 153 is moved forwardly, to retract the ejector of plunger, the spring 169. elevates the tongue 168 into the bore of the pocket or cylinder.

- The magazine 30 is constructed to hold a plurality of bullets 146, the number being determined by the capacity of the magazine. These bullets are not fed into the pocket or recess 128 by gravity, but are positively fed therein. To accomplish this, a carriage 174, Figure 3, is slidable within the magazine 80, and this carriage is provided with a radial.- extension 175, carrying a thumb piece 176, by means of which the carriage may be advanced. A rod 177, preferably rigid, is secured to the forward end of the carriage and passes into a compressible coil spring 178, and serves to prevent the buckling of this spring, whereby the spring could not improperly move out of the lateral opening 179, upon being compressed. This opening 179 is provided for the feeding in Secured to the opposite or rear end of of the carriage 174 is a suitably resilient element 180, which I have found may be advantageously constructed of a piece of steel music wire. I have this wire 180 resilient, in order that it may conform to the curvature of the rear part 30' of the magazine. At its rear end, the wire 180 carries a cylindrical head 181, which has substantially the same diameter as the bullet.

The numeral 182 designates a spherical head, which is slightly spaced from. the cylindrical head and is rigidly connected therewith bynieans of a shank 183. The

cylindrical head 182 is preferably of the same diameter as the bullet being used in the gun.

The numeral 184 designates an automatic bullet stop element, for the magazine. This element is pivoted at its forward end, by a pin 185, carried by the sides of the receiver, and a spring 186 is provided to swing the stop element upwardly. This stop element is provided between its ends with an upwardly projecting bullet engaging part or finger 187, having a curved pocket 188 formed therein, and adapted to snugly engage with the bullet. The finger 187 moves vertically through a slot 189 in the curved portion of the magazine. The stop element 184 extends rearwardly beyond its finger 187 and has an inclined face 190, arranged beneath and in alinement with the forward end of the keeper 166. The arrangement is such than when the keeper 166 is moved downwardly, for withdrawing the tongue 168 from the bullet receiving pocket, the stop element 184 is simultaneously moved downwardly and the finger 187 is withdrawn from the bore of the magazine. The reason for this operation will be readily understood, when it is seen that the bullet must be free to pass into the pocket when the keeper 166 is depressed, and the rearmost bullet in the magazine must be locked against moving out of the magazine, as the carrier starts upon its upward travel, the keeper 166 moving upwardly prior to this upward movement of the carrier. Hence, the bullet within the pocket of the carrier is securely held against outward movement, and the next'bullet in the magazine is held against discharging movement from the magazine, at about the time that the carrier starts upon its upward movement.

As is well known, it is very detrimental to an air gun to shoot the same when a bullet is not within the barrel, which is ordinarily termed snappingthe gun. To prevent this, I provide automatic means for preventing the placing of the plunger actuating spring under compression, when the last bullet is fedfrom a magazine, and introduced into the barrel and fired from the barrel, while the gun is being used as a repeater. This means embodies a rearwardly projecting extension or tail 191 of the stop element 184, which is arranged in the plane of a longitudinally extending lever 192. The lever 192 is mounted upon a pivot element 193, secured to the wall of the receiver. The forward end of the lever 192 is provided with a fork 194, which. engages upwardly beneath the rear end of the tail 191, while a spring 195, urges the fore ward end of the lever 192 upwardly. The

rear end of the lever 192 has a lateral extension stop 196, which is adapted to be moved into and out of the path of-travel of a lateral extension 197, formed upon the upper end of the trigger 89. It should be 9 the keeper 166 is moved downwardly for releasing the bullet from its pocket, the stop element184 is moved to the lowermost position, and hence the rear end of the lever 192 is moved to the uppermost position' When a bullet is positioned within the magazine 80, above the recess 184,0rwhen the spherical head 182 is in this position, the stop element 184 is adapted to move upwardly to its highest position, upon the upward, m vement of the carriage, and hen e the lever 192 will have its rear end moved downwardly to' the lowermost position.

1 most position, andwhen this, occurs, the stop element 84 is again depressed, releasing the spherical head 182, which has been held by the stop element as was previously done with the bullets. This spherical head now moves rearwardlyslightly toward the pocket, and

projects rearwardly beyond therear edge of the finger 187, but not rearwardly s'ufiicieritly to enter the pocket. This extreme rearward movementof the spherical head 1 82lori ngs'.the forward end of the cylindrical head181 over' the"forwa'rd". edge of the recess 188, whereby-thefstop element 184 is held in 'the int'erme'diateposition. The rearward movement of the spherical head 182 is defined or limited by theextension 175 engaging with the rear end wall 175 of the slot in themagaziiie. When this occurs, the stop 196 isarranged re-arwardly of and in advance of the path of travel'of the extension orstop 197 of the trigger. Now, when the lastbulletis fired, andthe operator again attempts to shoot the gun, it will be found that the plunger actuating springrcannot be placed undercompression, and this is effected because the upper end of the trigger 89 cannot move re'arwardly sufiiciently to effect a locking engagement with the forward end of the sear 7 21 This sear is self-releasing, but not self-locking. Thelever 62, may now be swung forwardly and rearwardly, with no other result than the reciprocation of the air chamber without compressing the spring.

I also provide means whereby the feeding of the bullets froin the magazine may be dispensed with, when desired, so that the gun may be used as a Sillg'lQSllOt gun, and also so that it may be used as a single shot gun when the bullets are exhausted from the magazine. This would also enable the bullets to be retained in the magazine, as a re serye, while the gun was used as a single shot gun.

This means is manually operated, and em bodies a lever 198, pivoted at its lower end upon the exterior of the receiver, as shown at 199.' At its upper end, this lever has a I milled thumb piece 200: This lever198 has pivotahconnection at 201 with a link 202.

This lever has a lower cam extension203, ar-

ranged above and engaging a stationary wardly of the finger 187.

urged forwardly, the cam extension 203 riding 'over the stationary element 204 simultaneously shifts the forward end of the link laterally or upwardly. This lateral shifting movement causes a shoulder bolt to bewithdrawn from a lateral notch 206 of a slot 2 07, formed in the wall of the receiver.

The shoulder bolt 205 is mounted within a longitudinal slot 208 in the link 202. This slot 208, permits of the initial movement of the link 202 forwardly, prior to the release of the shoulder bolt 205. This shoulder bolt is also adapted to engage within a latera depression 209 of the slot 207. The shoulder bolt 205 is rigidly mounted upon a magazine cut off stop element210, which is provided with a lateral extension or tongue 211, operating in the slot 189 of the magazine.

The extension or tongue 211 is arranged in shdable relation to the finger 187, upon one side thereof. The magazine cut off stop element 210 is provided with a longitudinal slot 212, receiving transverse pin 185, which pivotally supports the element 210 and also permits of its forward longitudinal movement. Hence, whenthe lever 198 is moved forwardly, the extension 211 is first shifted upwardly to engage behind the bullet or the spherical head182, as the case maybe, and when the forward movement of the lever 198 is completed, this bullet or spherical head is shifted forwardly sufficiently, whereby the bullet or head 182 is shifted entirely for- Hence. the stop element 184 may swing forwardly to the uppermost position, and there is no liability of the lever 192 restrictingthe rearward movement of the trigger. l Vith the parts thus adjusted, the air chamber may be moved rearwardly and this will uncover the main opening 42 in the guide cylinder and a bullet may be manually introduced into the rear end of the barrel. The sear will now look the plungerrod in the rear position, and upon the rearward .movement of the lever, the plunger actuating spring will be compressed. The bullet may now befired, as is obvious. I

It might be pointed outthat :when the gun is used as a single shot gun,'the lever .62 is moved forwardly sufiiciently to cause the air chamber to clear the opening 42, at which time the bulletmay be manually inserted into the. rear end of the barrel. Upon 'conr .pleting theforward movement of this lever, .the carrierwwillimove upward and the plunger or ejector supported thereby will "move into the rear end of the barrel and properly seat the bullet, as occurs uhenthe .gun isused. as a repeater. When the cylinder 1s aga1n.moved forwardly and the spring placed under compression. of course the carrier descends. as already described.

The operation of the gun or rifle as a repeater is as follows? The lever 198, Figures 1 and 14, being in the rear position, the bullets are free to be fed from the magazine 30, in a manner to be described. Starting with the compression lever 62 in the closed position, the air chamber 34 will be in the forward position, and the carrier will be in the lowered position, asmore clearly illustrated in Figures movement of the next bullets is prevented by engagement with the bullet in the pocket.

When the compression lever 62 is now swung forwardly upon the loading movement, the link 143 moves rearwardly and the keeper 166 is released, and automatically swings upwardly by virtue of its spring and a part of this keeper now projects in advance of the bullet within the pocket, securely retaining the bullet therein. Simultaneously with this movement of the keeper, the automatic stop element 184 moves upwardly by virtue of its spring action and the next rearmost bullet is engaged within the pocket 188 andv positively held against rearward move-' ment from the magazine. It is thus seen that at about the time the carrier begins to rise toward the barrel, the bullet within the pocket is securely held therein and the bullets within the magazine prevented from discharging therefrom. The rearward movement of the air chamber 34 brings the knuckles 69 in engagement with the upper inclined surfaces of the tail or cam elements 134 of the carrier, automatically effecting the upward movement of the carrier, whereby the pocket holding the bullet is brought into registration with the bore of the barrel, at the rear end of the barrel. A little after this registration is effected the transverse pin of the link 143 engages with the latch device carried by the link 156, releasing the latch device, and engaging the shoulder 157 of the link 156, shifting such link rearwardly, and advancing the ejector or plunger 151. As clearly indicated in dotted lines in Figure 8, this plunger will now push the bullet from its pocket and force the same into the rear end of the barrel. he plunger will project into the barrel for a substantial distance, whereby the bullet will be well seated in the rear end of the barrel. .The compression lever 62 will now start upon the rear or compression stroke. The first action is the bringing of the transverse pin 138 of the link 143 into engagement with the shoulder138 of the latch 159 carried by 156 is again locked against longitudinal movement. This retracts the ejector or plunger 151, and further forward movement of the air chamber 34 brings its forward end into engagement with the cam faces 135 of the carrier, returning the carrier to its low ered position. The keeper, ejector, and automatic magazine stop element are restored to the positions previously occupied, as above explained, and as shown in Figure 8. When the air chamber is shifted to the rearmost position, as above stated, the head or extension 41 of the plunger rod engages behind the holding part 84 of the self releasing sear 72, the sear being swung upwardly by the head 41 contacting with the extension 79. When the forward end of the sear moves upwardly the spring pressed plunger 92 swings the trigger upon its pivot and the upper end of the trigger moves toward the sear. This brings the engaging faces 88 and 87 into contacting relation. The plunger rod is therefore held against forward movement while the air chamber is advanced, and hence the plunger actuating spring is placed under compression. The instant the engagement is effected between the faces of the trigger and sear, the safety stop element 97 moves rear-wardly, and engages above the plunger rod 94, and the trigger is locked against pulling movement. When the compression lever 62 has completed its rearward movement, the pivot 66 between the link 6? and lever 62, is brought slightly outwardly of the pivot 64 of the compression lever, or out of alinement therewith, and this serves to lock the lever 62 and associated elements in the closed position, with the lever contacting with or adjacent to the stock25. This lever will now retain the finger release element or lever 112 in proximity to the lever 103, and when the operator grips the stock, inthe act of pulling the trigger, the release element or lever 112 will move the stop element 97 forwardly, allowing the plunger 92 to rise, so that the trigger may be pulled. If it should be. desired to prevent the pulling of the trigger, when the stock is gripped in the act of shooting the gun, the manually operated safety element is swung upwardly, and this will depress the sliding cylinder 107, causing it to move downwardly within the guide 104, so that its lower end will project flush with or below the arm 103 of the lever 101, constituting a stop for preventing the extension of the lever 112 from actuating the lever 101. The trigger will therefore remain locked against pulling movement until the manually operated safety element is shifted downwardly. The

adjustment of the lightness of the pull of the trigger, has been explained fully hereinbefore, it being sufficient to state that the lightness may be varied or. increased from a selected fixed lightness to a harder pull,

a'single shot gun or rifle, the bullet is introduced manually by the fingers through the opening 42 of the receiver into the rear end of the barrel. A particular advantage in my construction is that while the gun is thus being loaded the air chamber is in the rear position, and when in the rear position the plunger actuated spring is not under compression, and hence there is no liability of the air chamber driving forwardly upon the fingers.

It is to be understood that the form-of my invention herewith shown and described is to be taken as a preferred embodiment of the same, and that various changes in the shape, size, and arrangement of parts may be resorted to, without departing from the spirit of my invention or the scope of the subjoined claims.
