9 Claims.

This invention pertains to dispensing apparatus and in particular to a dispensing receptacle for cartridges.

Rifle cartridges are usually put up for sale in boxes of fifty, arranged in five rows of ten cartridges each. Preparatory to shooting, the cartridges must be removed from the box by hand one at a time, whether they are to be loaded directly into the firearm or into a clip or magazine which is then loaded into the firearm. For example, in target shooting it is common practice to load the firearm, whether pistol, revolver or rifle, with one shell at a time. when using a revolver, a single cartridge is placed in the cylinder in the revolver. In slow-fire target shooting with the rifle, it is usual to place one shell in the chamber of the rifle preparatory to each shot, and the same practice is followed when using a single-shot pistol. For rapid fire target shooting, it is customary to loadthe cartridges one at a time into a five or ten cartridge magazine or clip which is then inserted into the receiving chamber of the rifle. This is also customary in rapid-fire target shooting with a semi-automatic p s 01.

The cartridges are not very large. They are usually coated with a lubricant or protective material and have some tendency to stick together, and they are round and smooth so that it is not always easy to remove them one at a time from the box, particularly when the fingers are cold, without danger of dropping some of them onto the ground. It is not always convenient to find a support for the box, and the target shooter may be obliged to place the box on the ground where it remains open and where the cartridges may easily be covered with dust or grit which adheres to the lubricant on the cartridges, with consequent damage to the gun barrel. Even if, in an indoor range, there is a bench or table on which the box may be placed, there is always the danger that in trying to pick up a cartridge the box will be overturned and the cartridges spilled onto the floor.

To avoid the above difliculties,-it has heretofore been proposed to provide a block of wood or other suitable material having vertical sockets drilled into it into which the cartridges may be inserted after removing them from the box in which they are purchased, the block being heavy and of larger superficial area than the box, and having the cartridge-receiving holes spaced apart so that when once the cartridges are placed in the block they may more readily be removed one at a time for insertion in the firearm or in the cli or magazine. While the use 01' such a block represents an improvement over the withdrawal oi the cartridges directly from the shipping box for insertion into the firearm, the use of the block necessitates the removal of the cartridges from the box and their placing one by one in the sockets in the block before they are used. Since the block is purposely made of substantial size so that the cartridges will be spaced apart, and heavy enough to be stable, it can not well be placed in the pocket of the user or attached to his belt or readily held, so that the use of this block, although in some respects advantageous, does not avoid the substantial necessity of a table or other support in the near vicinity of the shooter.

The present invention has for its object the provision of a dispensing receptacle for cartridges so designed that the contents of a box of cartridges, as purchased, may be inserted into the dispensing receptacle as a unit and without substantially disturbing the orderly relative position which they occupy in the box in which they are received. A further object is to provide a dispensing receptacle so designed that, by

simple manipulation, one cartridge at a time is ejected and held in a position such that it may readily be seized between the thumb and finger and removed for insertion into the firearm. 'A further object is to provide a dispensing receptacle of a kind which protects the cartridges from dirt and moisture and which avoids all possibility of spilling the cartridges as they are dispensed one by one for use. A further object is to provide a dispensing receptacle which does not depend on gravity for positioning or ejecting the cartridges so that it is operative equally well regardless of the position in which it is held. A further object is to provide a dispensing receptacle of convenient size to be carried in the pocket or attached to the belt of the user, or which may be laid upon a table or even on the ground without danger of spilling the cartridges or exposing them to dirt. A further object is to provide a dispensing receptacle having indicator means to show to the user to what extent the supply 01' cartridges has been exhausted. Other and further objects and advantages of the invention will be pointed out in the following more detailed description and by reference to the accompanying drawings wherein:

Referring to the drawings, K designates the dispensing receptacle as a whole. This receptacle comprises a case which may be made of any suitable material, for example, a molded plastic, a molded metal such as aluminum or magnesium, or which may be made of sheet metal or the like. Preferably the case or frame of the apparatus, except for the removable cover hereinafterdescribed, is of unitary construction. It comprises the up member N (Fig. 1), the rear member l2, the front member I3, the bottom H, the internal web l5 and a guide portion l8. These several parts are so disposed as to define the cartridge-receiving chamber l'l (having the downward extension l8 which receives the cartridge follower, hereafter described), the chamber 9 which houses the trigger spring and a part of the trigger, and the guide channel 29. These several cavities are closed at the right-hand side of the recepticle by the thin wall or web B (Fig. 5) which is preferably integral with the parts I2, I 3, |4, |5, etc., although this member B may be a separate plate or cover suitably secured to the frame members l2, l3, l4, l5, etc., for example. by screws or rivets. As illustrated, the case is externally shaped to be grasped in the hand, with the fingers curled around the front "edge of part l3 (said edge being shaped to provide a secure grip) and with the thumb in operative relation to the trigger, hereafter described.

An ejector member or slide 2| is arranged to reciprocate in the guide channel 20. This ejector member 2| is a block of suitable material, for example, material similar to that from which the case itself is made, and is of a length, from front to rear, such that when disposed, as shown in Fig. 1, it laps over the upper edges of the members l3 and IS. The member 2| is of a width to extend transversely across the entire width of the cartridge chamber At its underside'(Fig. 6) the ejector member 2| is provided with a series of ratchet teeth 22. As here illustrated, there are seven such teeth, each tooth having a substantially vertical surface at its forward edge. Preferably the lower lateral corners of the slide 2| are rabbeted to provide grooves 23 (Figs. 5 and 6) for the accommodation of the rims of the cartridges. The forward or left-hand edge 21 of the slide or ejector member 2| is inclined upwardly and rearwardly, and the edges of this inclined surface are also rabbeted, as shown at 23* (Fig. 6) to accommodate the rims of the cartridges. The member 2| is provided with a bore 24, preferably internally screw threaded, for the reception of the shank of a stud or screw having a head 25. The head 25 constitutes a convenient handle for moving the ejector 2| manually. The upper wall ll of the case of the receptacle is provided with an elongate groove 26 (Fig. 2) to accommodate the shank of the screw, the head 25 being arranged above the upper surface of the member II and in a convenient position for actuation by the user. Preferably, as illustrated in Fig. 2, the top H of the receptacle is provided with numerals spaced along the slot 26 for cooperation with the head 25 of the actuating screw, thereby to indicate to the user the extent to which the cartridges have been exhausted.

The upper edge of the web member |5 of the case is provided with spaced vertical bores which receive spring-actuated friction pins 28 which bear against the under surface of the ejector member 2|, thereby frictionally to retain the latter in its retracted position, as hereinafter described.

A pivoted trigger member 29 (Fig. 1), fulcrumed at 30 on a pin fixed in the rear member l2 of the case, is movable in a front to rear direction in a slot 3| (Fig. 3) formed in the member l2. The upper rear'end of this trigger member 29 has a projection 32 for engagement by the user's thumb. A spring 33, housed in the chamber l9, tends to swing the trigger 29 rearwardly.

A pawl 34 is pivotally mounted at 35 near the forward upper corner of the trigger and within the chamber l9 and is urged upwardly by a spring 36. The guide member l5 of the case has a forward extension 23 which engages the pawl 34 and holds the latter down out of contact with the ratchet teeth 22 of the ejector 2|, except when the trigger 29 is moved forwardly so as to disengage the pawl 34 from the member 23m.

A cartridge follower block 31 is housed in the,

chamber l8, this block having a substantially flat upper surface 38 and having a cavity 39 which receives the upper end of a coiled compression spring 40. A pin 4| is housed in a horizontal bore in the block 31, and is urged forwardly, that is. to the left, in Fig. 1, by a coil spring. The inner surface of the member I3 is provided with a chamber 42 designed to receive the outer end of the pin 4| so as temporarily to hold the follower block 31 in depressed position such that the chamber l1 above the block is of a size to receive all of the cartridges contained in a box. A manually actuable plunger 43 is arranged in a bore in the forward wall |3 of the case and is designed, by manual manipulation, to disengage the pin 4| from the chamber 42, thus freeing the block 31 so that it may be moved forwardly by the spring 49.

A substantially L-shaped cartridge-controlling lever 45 (Fig. 'I) is mounted to swing in a slot at the upper end of the forward wall |3 of the case and is pivoted upon a transverse pin 46. A spring 41, housed in a cavity 48 in the upper part of the wall l3 of the case, urges the lever 45 in a clockwise direction. The forward or lefthand edge of the top H of the case has a fixed. upstanding cartridge-retaining hook 49 of a width substantially less than the length of the .cartridge. Preferably this hook or finger 49 is disposed about midway between the right and left edges of the case. The lever 45 has an upstanding arm 5|] normally reaching up nearly to the upper edge of the hook l9, and also has an inclined surface 5| (Fig.7).

The receptacle has a closure or cover M (Figs. 2, 3 and 5) which may be of sheet metal, plastic or the like, and which is preferably hinged to the case and held in normal closed position. for

example, by spring clips or the like (not shown) In using the device, the closure M is first opened, the ejector member 21 is drawn back to the fully retracted position, shown in Fig. 8, where it is retained by the friction pin 28, and the follower block 31 is moved down to the position shown in Fig. 1 where it is held by pin ll. The user then removes the cover from the box X oi. cartridges (Fig. 4), places the dispensing receptacle over the box so that the box registers with the chamber l1, and then inverts the box and receptacle, whereupon the entire mass of cartridges from the box drops as a unit into the chamber ll without disturbing the orderly arrangement of the cartridges, so that they are still arranged in parallel rows. The cover M is then replaced and the user depresses the pin 43 (Fig. 8) which permits the spring to push the follower block 31 firmly against the mass of cartridges in the chamber IT. The spring 40 is so designed as to keep the follower in contact with the cartridges in chamber I'I until the last one has been ejected.

When the user wishes a cartridge he pushes the trigger 29 forwardly, the first inward thrust of the trigger causing the pawl 34 to engage the forward tooth 22 of the ejector 2| and to move the first or top row of cartridges bodily to the left a distance substantially equal to the diameter of one cartridge. The trigger is now released and the pawl 34 is retracted beneath the part 23*, the slide or ejector being held in its advanced position by the friction pins 28. The operator now again presses the trigger, thereby pushing the foremost cartridge in the top row against the lever and swinging the lever 45 down to the position shown in Fig. 9. This position is momentary, for as soon as the forward cartridge C escapes from beneath the corner E of the top H of the case, the arm immediately acts to urge the cartridge upwardly, as shown in Fig. 10, and to place it so that it is partiallv embraced by the hook, the inclined surface 5| of the lever 45 helping to guide the cartridge up toward the hook. The cartridge is held in the hook by the finger 50, and the user may now easily pick the cartridge C out from between the members 49 and 50, the ends of the cartridge being freely exposed, as shown in Figs. 2 and 3.

On the next inward movement of the trigger 29, the top row of cartridges C is again advanced by an amount equaling the diameter of one cartridge, and thus the next forward cartridge in the row is ejected from the chamber and is caught between the members 49 and 50. This operation is repeated until all of the cartridges in the top row have been ejected. The position of the handle 25, relatively to the numerals on the top 1 6 repeated until all of the cartridges from the chamber I! have been exhausted.

While a desirable embodiment of the invention has been illustrated and described by way of example, it is to be understood that the invention is broadly inclusive of any and all modifications falling with the scope of the appended claims.
