Jb (1r/Z whom, it may concern;

Be it known that we, FRANKLIN K. YOUNG, residincr at Boston, in the county of Suffolk, State olf-Massachusetts and JAMES ESHERIFF, residing in the borough of Brooklyn, city of New York, in the county of Kings and State of New York, citizens of the United States, have invented a certain new and useful Improvement in Cartridge-Conveyers, of which the following is a specification, reference being had therein to the accompanying drawmgs. 1

The conveyer consists of a series of cylindro se mental holders linked together and adapte to be intermittently driven by mecharm, so as to convey the cartridges at the proper times into the position to be engaged vby the injector and pushed into the chamber. The conveyer is specially intended for use in combination` with an automatic firearm in which the conveyer is driven by a sprocketwheel actuated by the rearward movement of the weight; but it is not intended to limit the invention to use with any particular form of driving mechanism.

The invention will now be fully described, reference being made to the accompanying drawings, and the novel features thereof will be particularly pointed out in theclaims at the close of the specification. p

In the drawings, Figure 1 is a detail plan of thecartridge-conveyer embodying the invention. Fig.'2 is a rear elevation of the conveyer. Fig. 3 is an enlarged vertical section on line 3 3 of Fig. 1. Fig. 4 is an enlarged section on line 4 4 of Fig. 1. Fig.. 5 is a p an of a modification of Fig. 1. Fig. 6 is a rear elevation of Fig. 5. Fig. 7 is an enlarged sec tional view on line 7 7 of Fig. 6. Fig. 8 is a side elevation of a pin employed to attach a loaded cartridge-conveyer onto one that is partially exhausted of the modified form shown m Figs. 5 and 6. Fig. 9 is a vertical cross-section through the breech mechanism of. a firearm and the table which supports the improved cartridge-conveyer.

Referring now to the drawings, each holder 1 is of cylindre-se mental shape. The end of each holder whic points toward the rear of the firearm, Yas the conveyer travels in a transverse direction relative to the'length of the firearm, is closed by a wall 2. 1The end wall of each holder is fastened to a link S-as by rivets 4, for instance, (see Fig. 3)and the links 3 are connected with each other by pins 5, thus forming a chain which carries the holders. The inner ends 6 of the pins 5 are riveted or headed to prevent them from drawin@ out, and the Shanks are formed with an enlarged neckportion 7, which extends outward from the chain, terminating in a head 8. The necks 7 engage with the notches 9 in the periphery of the sprocket 10. The heads 8 form guards to hold the 'chain on as it passes over the s rocket.

Forme in the upper edges of the holders near the chain side are inwardly-extendingprojections 11. The cartridges are inserted into the holders by forcing them base first into the open ends of the holders, the sides of the holders springing apart sufficiently to allow the flange on the rear end ofthe cartridge to pass the prjections 11, after which the said projections 11 will snap into the circumferential groove in the cartridge-case.

A table 12 is preferablyprovided connected with the piece which supports the conveyer and cartridges as they approach the sprocket. (See Fig. 9.) The table is provided with upwardly-extending side walls 13, which guide the cartridges and conveyer.

In the modification' shown in Figs. 5 to 8 there is shown a modified means ofconnect- ,ing the holders. The holders 14 are formed with'lugs 16 on the sides, which are perforated to receive the link-pins 17. formed with necks 18 and the-heads 19 for the same purpose as the necks and heads of the pins 5. The last pin in each conveyer is made detachable in Order to attach another conveyer to the nearly -exhausted one, but

should be held in place so as not to be easily.

displaced by the operation ofthe mechanism. In the formv shown in Fig. 8 the pin 17l is formed with a slightly-enlarged split point 20, the split allowin the enlarged portion .to be contracted and s oved through, the holes in the lugs 16, and after it is assed through the expansion will hold it in p ace.

Mechanism by which the sprocket-wheel 10 is given its intermittent movement to bring the cartridges into position at the proper time is shown and described in an ap- The pins are IOO plication led by us in the United States Patent Oflce December 7, 1903, Serial No. 184,087, of which this is a branch application, and as that mechanism is the, subject of 5 claims retained in that application itis not shown in the drawings accompanying this application. j v

Theyzsprocket 1() is mounted on a rotatable cylind'er21, which also carries a ratchet 22, o Awhich rotates with the cylinder.

The Weight consists of a cross-head, a cylinder fixed thereto surrounding thebolt 23 in the receiver 24, a firing-pin projecting from said cross-head through the bolt, and a 5 rod 25, which isjixed to said cross-head and -passes through the cylinder 21. The crossheadweightcylinder, and firing-pin are not yshown in the drawings accompanying this f a'lpplication. The rod 25 moves as a part of a t 'e weight and has connections whereby its rearward movement rotates the cylinder 21 and sprocket 10, and thereby actuates the conveyer.` The vratchet 22 engages with a pawl pivoted tothe frame to prevent back- 5 ward rotation of the sprocket. Y

f vThe cartridges are pushed by the injector (not shown) up the inclined way '26 into the chamber. f

-In the form shown in Fig. 2 vthilast link of each conveyer is formed with -a hook 15,

which will hook over the neck i of the first pin of another conveyer.

' What we claim 1. A 4cartridge-conveye'r comprising a series of`cylindro'segmental cartridge-holders hinged togetherby pins, the pins projecting laterally beyond the holders and formed with a flanged head and a neck adapted to be engaged by a sprocket-wheel.

2. A cartridge-conveyer comprisino' a series of cylindro -segmental cartridge-holders hinged together, having pins'which roject from Abetween the holders laterally eyond the ends of the holders, and adaptedto be engaged .by a sprocket-wheel.

3. A cartridge-conveyer for rearms com.-

prisin'g a series of cylindro-segmental cartridge-holders hin ed together, a wall at the rear end of each ho der, the hin e-pins having a neck Which projects lateral y and terminates in a flanged head, the projecting neck portion of the hinge-pins being adapted for engagement by an actuating sprocket-wheel.

4. A cartridge-convyer for firearms coinprising a series of cylindro-segmental cartridge-holders hin ed together, a wall at the rear end of each older, the pivots of the hinges having necks which project laterally beyond the ends of` the holders, and are adapted for engagement by a sprocket-wheel.

In testimony whereof we aliX our signatures each in presence of twowitnesses.
