' application, filed To allwho'm it may concern;

Be it known that I, NiLs BJGRGUM, a subject of the King of Norway, residing at Asker," near Christiania, Norway, have inifvented certain new and useful Improveaccompanying drawings, and to letters on figures of reference marked thereon, which form a part of this specification.

My invention relates to improvements in cartridge feed-belts and is a division of my August 22, 1910, Serial No. 578,4-l2.

- The object of the invention is to provide a cartridge feed-belt which will serve as a steady support for a cartridge when it is brought into position for being gripped by a conveyer such as shown in my original application, and which 'takes the cartridge to the chamber, said .belt allowing the cartridges to be removed easily 'therefroin in the axial direction of the cartridge.

'My invention consists in forming the belt entirely of metal and providing means to secure a correct position both during transportation and the feeding operation. "The belt is so constructed that it is both light and strong so that very little force is necessary for pulling i cartridges out of the ssbl In the accompanying drawing-Figure 1 i is a cross section of a belt member, a plurality of which compose a belt embodying my invention. Fig. 2 is a longitudinal section of the same. Fig. 3 is an end view of one member. Fig. 4 is aside view thereof. Fig. 5 is a longitudinal section through a belt member in which a cartridge is inserted. Figs. 6' and 7 are end and plan views respectively of a plurality of belt members, the upper two carrying cartridges. Figs. 8 and 9 are end and plan views respectively of-a single member drawn on a smaller scale.

The belt consists of a plurality of tube likemembers 1 made of a single piece of metal having knuckles 2 formed on each side, said k'nuckles being so disposed that those of one tube willpiit between the kn'uckles of another tube (Eig. 7 and are joined by a pin 3 which passes through the knuckles and-on which the tubes turn forming a flexible connection. Any number of tubes may be thus hinged together to for-in a continuous belt of any desired length.

The tubes are preferably provided with side openings 4;, for the sake of making the belt as light as possible. At the front end of each tube the metal is bent toform a flange 5 which fits closely around the projectile 6 to steady it. At the rear end arms 7 are formed having inwardly bent lips 8 which snap into the groove 9 of the cartridge shell 10. These arms form spring. latches which keep the cartridge in a correct position. I

1 1 claim- 1. A cart-ridge feed-belt composed of a plurality of tubes each shorter than a cartridge, each tube having its front end bent inwardly to form a flange adapted to enintegral hollowknuckles pressed therein to form lateral hinge members for interconnectingthe tubes.

In iastimony that I claim the foregoing as my-invention, I have signed my name in presence of .two subscribing witnesses.
