7- Claims.

This invention relates to a cartridge feeding arrangement for guns, and aims to provide a novel and improved mechanism of this character f which will permit the supplying of cartridges i continuously. the same being more especially adapted for use in connection with automatic and semi-automatic guns of large calibres.

Another object is the provision of a positive feeding shuttle in the housing operatively con- @i nected to the breech mechanism for feedingeach cartridge to the position of the preceding one upon each reciprocal movement of the breech mechanism for extracting a cartridge case and feeding a cartridge, and at the same time per- 5 mitting the lling in of any number of cartridges fed from the housing during the time required toreplace another clip on the housing.

A further object of the invention is to provide a swinging cartridge positioning bracket for receiving the cartridges from the housing and psitioning the same in front of the bolt of the breech mechanism, said swinging cartridge bracket being operated by the breech mechanism y and arranged to hold the cartridges directed to- '5 ward the chamber of the barrel until thepoints of the projectiles thereof have actually entered the chamber of the barrel by movement of the of Fig; l,

bolt thereby.

A still further object is the provision ofv a pair 50 of cartridge rests pivotally carried by the receiver, one at each side thereof, upon which the cartridges are placed by the swinging cartridge bracket, when positioning the cartridges to enter the chamber, said cartridge rests being swung m on their pivots by reciprocatory movements ofy the bolt in the receiver and being arranged above the center line of cartridge cases being extracted from the chamber forengaging the cartridge cases and forcing the same from the-receiver. ttl' Another object is the arrangement of a mechanism controlled by the cartridges in the housing for catching the breech mechanism in its rear position when the last cartridge leaves the housing, the same being so constructed that after i@ ,the housing has been emptied and a new supply of cartridges have been' furnished, the breech mechanism will be automatically released and moved to closed position for feeding the first of said cartridges into the chamber ready to bered on operation ofthe trigger;v

It is also an object'of the invention to provide a cartridge feeding arrangement of the character indicated, which will be substantial in construction, which may be conveniently associi ated with guns during the manufacturcthereof,

\ mechanism, said breech mechanism also'includes and which will be thoroughly eiiicient and practiycal in use.

With the foregoing and other objects in view which will be apparent as the description proceeds, thejinventionresides in the construction and arrangement of parts, as hereinafter described and claimed, it being understood that changes can be made within the scope of what is claimed, without departing from the spirit of the invention. 7 K l@ The invention is illustrated in the accompanying drawings, wherein: Y

Fig. 12 is a similar section online iii-i5 -of Fig. 4, showing the breech mechanism in its rear position. v

Referring to the drawings, the numeral i0 designates the receiver of a gun having opposite lside walls i! and i2, a top wall i3 provided with a feed opening It near the forward end thereof, and a front portion i5 into which is secured the rear end ofa barrel it.

Slidably mounted in the receiver for reciprocatory movement and guided by rail il on the side walls Il and l2 is a bolt i8 of a breech:

a Avertical movable lock I9 carried by the bolt and a lock actuating member 2li slidably mounted in the receiver and arranged to be reciprocated with the bolt.

A rod 2l extends through the forward portion 55 f barrel.

On the rear end of the receiver I0 is a rear plate 23 which carries the rear ends of the return springs 22, and which is held in place by a rear closure member 24 attached to the opposite side walls II and I2 of the receiver.

In carrying out the invention 25 and 26 indicate the opposite disposed sections of a cartridge housing 21 attached to the receiver Ill-by means of bolts 26 extending through depending flanges carried by the sections 25 and 26, and arranged on lopposite sides of the receiver, said housing being positioned at the opening I4 in the receiver so that cartridges in the housing will be fed through said opening into the receiver. The two sections 25 and 26 are provided with forwardly and rearwardly extending flanges 29 at their adjoining or abutting front walls 30 and rear walls 3|, through which bolts 32 extend for attaching the two sections of the housing 21 together. Also arranged for attaching the housing 21 to the receiver is a ange 33 carried by each of the sections 25 and 26 at their forward-portions, which are secured to the receiver by means of bolts 34. From the foregoingit can be seen that a housing 21 has been provided having front and rear walls 30 and 3l respectivelrfand opposite side walls 35 and 36.

Carried by the front wall 30 of the sections 25 and 26 is a pair of inwardly extending longitudinal guide ribs 31 for engaging the nose of pro'- jectiles of cartridges, while carried on the side walls 35 ,and 36 are -oppositely disposed guide ribs 38 for engaging the rie band of projectiles of cartridges, and while also carried by the side walls 35 and 36 are guide ribs 39 positioned slightly forward from the rear wall 3l of the housing for engaging into the extractor grooves of cartridge cases.- By providing the vertically extending ribs 31, 38 and 39, it can be seen that cartridges arranged in th housing 21 will be held in proper position at all times, a structure of this kind being very essential when feeding cartridges having extraction flanges thereon of greater diameter than the bodies .of the case portion, as the above referred to structure will prevent the flange of one cartridgegcase engaging into the extraction groove of an adjoining cartridge case.

The side wall 36 has two rows of openings 49 and. 0H provided therein, each row extending upwardly in a vertical direction, and each opening having pivotally arranged therein, as at 42, a pawl @3 for engaging the cartridge cases to hold the same against upward movement. Each of the pawls d3 has a spring 44 thereon for yieldably holding the same against a stop and in position for preventing the cartridges from backing up. By referring to Figures 9 and 10 of the drawings it can be seen that the pawls 43 are of a formation for not only holding the cartridges against upward movement in the housing 21, but also have surfaces 46 thereon for engaging and supporting the weight of the cartridges above the ones being held, said springs 44 being of suicient tension to serve this purpose.

In the side wall 35 opposite to the one carrying the pawls 43 is arranged a guide-way 41 for slidably supporting shuttle bar 48, which is also provided with two rows of openings 49 and 50 therein, positioned directly opposite to the two rows of openings 40 and 4I in the side wall 36. In the openings 49 and 50 are pivotally carried pawls 5I, having springs 52 for yieldably holding the same outwardly, and stops 53 for limiting the outward pivotal movement of the pawls 5I. Also on the pawls 5I are arranged surfaces 54 for engaging the shells above the ones to be moved by the pawls 5I in order to support the same during the time the shuttle bar 48 is in its uppermost position.

With the above referred tol arrangement of pawls it can be seen that the pawls 43 will hold the cartridges against upward movement in the housing 41 when the shuttle bar 49 is moved upwardly Y in order that the'p'awls carried thereby may engage the cartridges directly above those just engaged, andwhen the shuttle bar is moved downwardly all of the cartridges in the housing 21 will likewise be moved downwardly until the same are engaged by the pawls 43, to hold the same in proper position.

Extending outwardly from the shuttle bar 48 is a lug 55 received in an-outwardlyformed compartment on the side wall 35. The lug 55 extends downwardly and is slotted as at 5S to receive the upper end of a shuttle connecting bar 51, said bar 51 being pivotally connected to the lug 55, as at 58, while the lower end of the bar 51 is pivotally connected, as at 59, to the forward end of a rocking arm pivoted to the wall Il of the receiver by means of the pivot pin 6I. On the rear end of the rocking arm 60 is a roller 62 positioned in a cam groove 63 in a lower frame construction 64 carried by the lock actuating member 20.

The rocking arm 60, cam groove 63, connecting bar 51, and shuttle bar 48 are so positioned and arranged with respect to one another that when the breech mechanism is moved rearwardly in the receiver, the shuttle bar 48 will be pulled downwardly for feeding cartridges, and when the breech mechanism moves to closed forward position the shuttle bar 48 is raised so that the pawls thereon engage the cartridges above the ones just engaged to move the same to the positions of the preceding ones when the breech mechanism is again retracted. It will be noted that the caml groove 63 is slightly inclined for a considerable distance as it extends forward, that the same is then provided with astraight horizontal portion, and that the forward end of the cam groove is open. By having the inclined portion of the cam` groove of considerable length and at a very slight angle, cartridges being fed will be handled more gently than if la. greater angle for the cam groove was provided. The straight portion takes care of varied rearward movement of the breechI mechanism, while the open end permits removal and assembly of the breech mechanism. The compartment that `receives the lug 55 of the shuttle bar extends downwardly, as at 65, and also has contained therein the .bar 51, andhas grooves arranged therein for slidably receiving a removable plate 66 for permitting access to the various pivotal connections between the rocking arm 60 and the shuttle bar 48.

The lower portion of the side walls 35 and 36 of the cartridge housing 21 lare enlarged, as at 61, as is the opening I4 for receiving the forward feed arms 68 and 69 of a substantially H-shaped swinging cartridge bracket 10. 'Ihe rear arms 1I of the bracket 10 are received in slots 12 in the..

top portion I3 of the receiver and are pivotally connected to the receiver at their rear terminal by means of trunnions 'i3 extending through openings in said arms and carried by threaded portions Ed 5secured in the receiver by threading the same inwardly from the opposite sides thereof.

The connecting portion 'i5 of the H-shaped bracket l@ is also received in a cutaway opening It in the top of the receiver and has an upstanding lug il thereon about which is arranged the IlowerA end of a coil springl for yieldably holding the swinging cartridge bracket in its downward cartridge feeding position.l Attached' to the top wall I3 of the receiver is a housing l@ for enclosing the rear portion of the bracket 70, which is provided with a threaded opening 80 for threadably receiving the lower end of a spring chamber @I that extends upwardly and supports the upper end of the spring llt.-

Each of the arms @E and SQ of the pivoted cartridge bracket it has a pair of upwardly extendingportions Q2 which carry feed pawls t3. The feed pawls of one arm of the bracket are arranged directly opposite to those on the other arm te thereof, and the forward pawls on both arms are arranged to engage a cartridge between the points where the cartridges are engaged by the pawls i3 of the side wall 36 and between the pawls 5i on the shuttle d8, while the rearward,

pawls on the feed arms te' and 69 engage the cartridges slightly forward of the extraction iiange portion thereof. The pawls 83 are pivotally carried by the feed arms td and S9 and have springs i355 connected thereto for normally holding the same in outward position for engaging a cartridge and are limited as to their outward swing movement by means of stop portion 85.

The lower edges of the arms S9 are engaged by the bolt I8 of the breech mechanism for controlling movement of the swinging cartridge bracket. When the breech mechanism is in its forward closed position the swinging cartridge bracket will be raised,` and when thevbreech mechanism is moved to its rearward position and to the rear of the forward arms 623 and 69 the spring 18 will swing the bracket downwardly and the pawls d3 thereof will cause the'shell engaged thereby to .als9 be swung downvrdly and in front of thel bolt of the breech mechanism. By having the `lower edges of the arm portions B8 and 89 angled as at 86 and provided with a short straight portion, as at 81, and 'having said angled portion d@ and straight portion' 87 positioned on the arm with respect to the position of a -cartridge being carried by said arm, it can be seen that the particular time in which it is desired to raise the -cartridge bracket to its upper position can be determined, and this time is 'when the bolt of the breech mechanism has moved forwardly a sumcient distance to cause the nose of the projectile of the cartridge to enter the chamber of the barrel. With the angled surface 86 arranged at such point, it will not cause the feeding of a shell downwardly prior to the time the bolt of the breech mechanism is in rear of the cartridge, as the cartridge itself is the element which holds thev bracket against swinging movement by the spring IQ after the bolt has passed the straight I portion 8l and is still moving rearwardly.

0 Attention is now directed to the opening Id in the top wall I3 of the receiver through which the cartridges are red from the cartridge housing 21, which clearly illustrates in Fig. 7 of the drawings the opening lli as being of a shape substantially a .to that of a cartridge. 'I'he forward end. of the Vdownwardly from the extractors of the-bolt and opening is curved similar to that of the nose of the projectile of a cartridge., as at 8E, while the opening It is enlarged in width at a point substantially midway of its length as it extends rearwardly, as'at B9. At the enlarged place 89 the seat portion of a cartridge case is adapted to pass while moving downwardly from the cartridge housing 21 into the receiver. The opening I6 at the portion 89 thereof is enlarged at the lower side-walls for providing guide surfaces 90 to be: engaged by the tapered portion of the cartridge case to cause the cartridge to be directed downwardly when moved slightly forward, thus preventing either the nose of the projectile or the base of the cartridge'from raising when the carl5 tridge is engaged and moved by the bolt I8.

On the side walls li and I2 of the receiver lll, substantially midway of their length, is pivotally mounted, as at SI, a pair of cartridge rest arms 92 and 93. VThe arm t2 is carried by the sidelv wall Il, while the arm 93 is arranged in the side wall I2. The arms g2 and 93 are pivotally mounted intermediate therein, with both the forward ends 90 and the rear ends 95 angled inwardly to be engaged by the bolt of the breech mechanism 1 during reciprocation thereof in the receiver for swinging the forward ends 96 of said arms inwardly or outwardly according to the position of tle bolt. When the bolt I8 is in its rear position the forward end @d of the arms 92 and 93 are;` held inwardly by the bolt so as to form a rest for a cartridge being fed downwardly by the swinging cartridge bracket l0, and kremains in such position until a portion of the cartridge has been fed into the chamber of the barrel. As bolt lmoves forwardly-the forward ends 96 of the arms 92 and 93 will enter the slots 93a in the bolt and be cammed outwardly, thus causing the rear ends 95 of said arms to be swung inwardly. Afterl the cartridge in the chamber has been iired and thebolt of the breech mechanism is moved rearwardly to extract same, said bolt engages the rear ends Q of thearms, swingingthe forward ends 94 thereof inwardly so as to eject the cartridge case being extracted from the chamber, and as the` cartridge case is pulled straight back from the y chamber of the barrel the forward end of the arms 94 will engage: the same slightly above the centerfof said cartridge case and force the same from the receiver. f

Arranged forwardly of the forward end 96 of the arms 92 and 93 is a Ipair of spring urged cartridge rests-96 and 91 on which the projectile of the cartridge rests so asto hold the nose of saidI 5 projectile in direct alignment with the chamber of the barrel. These spring urged cartridge rests 95 and 91 are also actuated by the bolt I8 of the breech mechanism, so as to be forced outwardly when said bolt is moved to forward or closed position, and to spring inwardly for supporting the next cartridge 4when the bolt has been retracted past the point of location of said element.

Extending rearwardly from the back plate 23 is a pair of ears 98 which pivotally support, as at. 99, an L-shaped latch member IGI), having an upstanding arm portion I0! and a forwardly extending arm portion |02 provided with acatch |03 on its forward end. The catch |03 is adapted to engagea downwardly extending lug carried at the rear end of the lock actuating element 20 for holding the breech mechanism in rear position. The upper end of the arm portion IIlI of the latch member `is pivotally connected to the lowerend of an arm |05 fixed to one end of a- 16 shaft |06 which is journaled in a lug |01 also carried by the rear plate 23 and extending rearwardly therefrom. Fixed to the opposite end of the shaft |06 is an upstanding arm |08, the upper end of which is formed, as at |09, vfor engagement with the rear end of'a sliding rod ||0 mounted in the upper portion of the receiver |0. The forward end of the rod ||0 abuts against the lower end of a lever which is secured at its upper end, as at ||2, toa trunnion ||3 of a swinging member ||4 normally arranged in a recess ||5 provided in the rear wall 3| of the cartridge housing 21, said swinging member being pivotedvto the housing as at H6. A spring ||1 is positioned between the back plate 23 and the upstanding arm portion |0f' of the latch member for applying a force tending to hold the catch |03 on the member '|00 yis a position for engaging the lug |04 of the lock actuating member and to hold the swinging member I I4 outwardly into the path of movement of cartridges arranged in the cartridge housing 21.

By the above referred to arrangement it can be seen that when cartridges are positioned in the housing 21 the lowermost of which will hold the member` ||4 in its rear position with the catch |03 out of position for engaging the lug |04, and against tension of the spring] |1f. From the above it can be seen that when the cartridge housing 21 runs empty of cartridges the spring ||1 will be permitted to swing the member ||4 forwardly so that the catch |03 of the -latch member |00 upwardly to engage the lug |04, and that when cartridges have been supplied to the housing the cartridges themselves will force the member ||4 rearwardly thus disengaging the catch |03 from the lug |04 and permit the breech mechanism to be moved forwardly by Ameans of the springs 22 and thus feed a cartridge into the chamber of the barrel.

In case it is desired to release the breech mechanism from its rear position without the feeding of a cartridge into the chamber of the barrel, a plunger element |8 is carried` by the rear cover member 24\which consists of a bushing 9 threaded into the wall of the c'over member 24 for slidably receiving a bar |20 having a head |2| on its forward end for engaging the arms |00 and |05 at the point of their pivotal connection, and a hand engaging knob |22 on its rear end, exteriorly of said closure member.

In operation cartridges are placed in the cartridge housing 21 with the breech mechanism in its forward position, such as that illustrated in Fig. 3 of the drawings, andthen the breech mechanism is pulled back by hand, by the structure illustrated in Fig. 4 of the drawings, and to the position illustrated in such figure. Upon release of the breech mechanism the springs n22 -will force the same forwardly feeding the cartridge held down in front of same by the swinging cartridge bracket into the chamber of the barrel, where said cartridge is fired, supplying a sufficient amount of power for moving the rod 2| rearwardly. Such rearward movement of the rod 2| applies pressure on the lock actuating member 20 to withdraw the lock, I9 from locked position and then move said lock actuating member 20, lock |9, and bolt 8 rearwardly, extracting the spent cartridge case from the chamber of the barrel.

During the rearward movement of the breech mechanism the yieldable cartridge rests 91 are permitted to spring inwardly towards one another as soon as the forward end of the bolt hi passed same, and the rear end of the rockir bar 60 is moved upwardly by the cam groove I arranged on the lock actuating member 20, whic causes the forward endof said locking bar to be moved downwardly thus pulling the cox necting rod 51 downwardly, which in turn pul the sliding shuttle 48 downwardly and the pawl 5| carried thereby will feed each cartridge i the housing 21 downwardly to the position of tk preceding cartridge, the lowermost of 'said car tridges being fed to a position to be engaged b the pawls 83 carried by the forward arms E and 69 of the swinging cartridge bracket 10.

As the breech mechanism continues to mov rearwardly the rear ends 95 of the pivotedcar tridge rest arms 92 and 93 are engaged by th bolt of the breech mechanism which causes th forward end 94 of said arm to be swung inwardl; towards one another to engage the spent cartridg case being extracted from the chamber at 1 point above the center line of the cartridge s1 as to' eject the same downwardly from the fac of the bolt and through the receiver. When th bolt of the breech mechanism has been mover rearwardly to a position to the rear of the hear of the cartridge held by the swinging cartridgi bracket 10 the spring 18 will swing said cartridge bracket downwardly, positioning the cartridgi held thereby in front of the face of the bolt with the nose of the cartridge resting upon the yieldable cartridge rests 96 and 91 and the case portion of the cartridge supported on the forward end 94 of the cartridge rest arms 92 anc' 93. The cartridge then is in a position directed towardsthe chamber of the barrel I6, and held down upon the rests 96, 01 and 94 by the pawls I3 on the swinging cartridge bracket 10.

When power is relieved from the rod 2|, the springs 22 will move' the breech mechanism in a forward direction. The face of the bolt |8 engages the base of the cartridge and slides the same forward between the various cartridge rests and the pawls 83 until the nose of the cartridge has entered the chamber of the barrel. At such time the bolt engages the angled surfaces 86 on the arms 68 and 69 to cam the forward end *of the swinging cartridge bracket 10 upwardly to a position whereby the surfaces 81 of said arms 68 and 69 ride on the top surface of the bolt. As the breech mechanism continues to move forwardly the forward end 94 of the pivoted cartridge rest arms 92 and 93 will be swung outwardly, as will the yieldable cartridge rests 96 and 9-1. Also during such `forward movement of the breech mechanism the cam 'groove 63 will swing the rocking arm to a position for raising the shuttle 48 in the cartridge housing 21, so that the pawls 5| carried by the shuttle 48 will engage the cartridges above those previously engaged.

During such raising of the shuttle 48 in the car'- trldge housing'21 the pawls 43 will hold the cartridges in said housing from being raised by the pawls 5| carried by the shuttle. It will be apparent as the bolt |8 of the breech mechanism continues to move forwardly the cartridge in front of same will be fed into -the chamber of the barrel .where the same will be fired and the operationA continued.

Should the housing 21 run empty of cartridges the pivoted element |4 arranged in the lower rear rportion of the housing 21 will be permitted to swing forwardly by the pressure applied on the arm |0| by thespring ||1, which will cause the catch |03 carried by the lever |00 to engage the lug |04 on the lock actuating member of the breech mechanism, thus holding the breech mechanism in itsrear position. By then placing another clip on the housing 2l and feeding the cartridges therefrom into the housing the lowermost of said cartridges will engage the pivoted element lili forcing the same rearwardly, which will cause the catch it to disengage the lug I Ut and the lowermost of said cartridges just supplied to the housing will be fed into the chamber of the barrel by closing of the breech mechanism.

With this arrangement it can be lseen that should the clip not be placed on the housing 21 prior to the emptying thereof, firing can be resumed without the necessity of retracting the breech mechanism by hand.
