Application'March 1, 1944, Serial No. 524,565 ì 10 Claims. (o1. sei-4s.) (Granted under the act of March 3, 1883, as , amended April 30, 1928; 370 O. G. 757) . 1 ` 2, f ' e f The invention described herein may be manu factured and used by or for- the Government for For unloading, the cartridges are placed in the grooves 2 with points toward the pusher bar 6 governmental purposes without »the payment'to and a jig 9 is placed over the machine to hold the links 5 while the pusher bar 5 forces the car tridges out of the links. The jig 9, in a preferred embodiment, com me of any royalty thereon. » This invention relates to ammunition belt load ing machines in generaLand in particular to a modification thereof in the form of an adaptor prises-a framework having two similar end pieces providing for unloading operations. It is frequently necessary to unbelt and rebelt ammunition. When ammunition is unbelted by hand, the link is often twisted so as to bind, and a much greater force is required to free the car tridge from the link, resulting in forcing the v10 I@ and a center piece III' and cross-bracing mem bers Il and i2. Fastened to cross member I2 is a series of parallel spacers I3 designed to overlie the ridges Ill between grooves 2 to form slide com partments for the separate cartridges and to form, at their rear, a stop for the links 5. Slots i5 in the end pieces and :center piece receive the percentage of short rounds. On the other hand, 15 links. The iront ends oi spacers I3 abut against the ridges I6 between serrations ¿I in the front ii a cartridge is pushed straight out of a link the ilange 3. A handle Il facilitates placing and re Íorce required .is much less and the probability moval of the jig. of short rounds is considerably lessened. , With the belt in place with cartridges reversed According to the invention, a jig is provide which is adapted to be used with the ordinary 20 and the jig set thereover, the pusher bar 6 is actuated by means of the handle 'I. The thrust gang belt loading machine, which holds the car is ñrst communicated to the points of the car tridges in such manner that only a straight axial tridges and hence the links E. Since spacers I3 force is applied. are stopped by ridges I5, the links are held while It is therefore an object of the invention to provide for unloading of cartridge belts by ‘ the cartridges are pushed therefrom by action of pusher bar 6 and the cartridges being steadied by straight axial pressure. >spacers I3, the thrust is continued in a straight It is a further object of the invention to pro line without distortion of the links. vide a device whereby a belt loading machine will The rear cross-bracing member II and mem be adapted for unloading purposes. The speciiic nature of the invention as well as 30 bers IB and Iii' serve the additional function of forming a stop for the pusher rod t so that it will other objects and advantages thereof will clearly bullet into the cartridge case and causing a high appear from a description of a preferred embodi ment as shown in the accompanying drawings in which: Figure 1 is a top plan view of the belt loading machine with reversed cartridges and with the unloading jig in place. _ ' not continue forward to damage the points or jam the bullet into the cartridge case after the cartridge has been freed from its links. It will be seen that the device of the invention is simple and speedy, permits an additional use for a machine already in use and results in more eñicient operation of unloading with fewer short Figure 2 is a front perspective View of Figure 1. rounds.
