The original Gatling'weapon uses a filler box, which is on the weapon and works by gravity. Accordingly, U.S. Patent No. 29o 622 of Jan. December 1883 a positive screw-shaped magazine feed for the Gatling weapon can be seen. After that, in particular under the direction of F. Bailey and H.P. Maxim Belt feeds introduced either in continuous form or as chain links. See in particular the Aufastz "The Machine Gun Belt" by Jim Crossman in the Book "Tfre American Rifleman", December 1966 edition, pages 46-49 · Deviating from the suggestion to use belt feeds, Miclus proposed in US Pat. No. 1,136,695 from 2o. April 1915 presented a linear, chain linkless feed system. The magazine had several vertically oriented Supply channels, each of which had a series of cartridges under a downward Peders tension stood. An endless conveyor belt below the magazine emptied each channel completely, starting at the furthest point lying channel and transported the row of cartridges one after the other to the weapon. For supplying a Gatling weapon after US Patent 2,849,921 was recently with US Patent 2,935,914 of 10.

To achieve assembly of pins 194 and 194b, which are driven by ■, the transport rollers 72 and 74. The rollers 196 and 198 are designed so that they can be guided in the rear guide surfaces 64 and 66 and in the front guide surfaces 68 and 7o. The projections 200 on the members 178 are cylindrical and support the respective elements 24, 26, 28, 30 and 32 which are located away from the respective web portions. The projections 2o2 on the links T8o carry the element 34 which is removed from the corresponding web part and which has a cutout 2o2a in order to be able to grip the corresponding transport roller. The element 34 also has a cutout 34a in order to be able to engage in the adjacent transport roller. The projections 2o4 on the links 174 have a corresponding shaft 2o6, which stand upright therefrom, on which the transport roller 38 is fixed in order to be able to rotate between a lower pressure disc 2o8 and an upper pressure disc 21 o, and is driven by a key pin 212 held. The transport roller 38 has a central tubular part 214, furthermore an upper end plate 216, which has 5 teeth 218 and 5 recesses 22o, and a lower end plate 222, which has 5 teeth 224 and 5 recesses 226. The lower plate 222 has a peripheral notch 228 and each tooth 224 has an arcuate notch 23o in each lower surface. The guide element 22 consists essentially of a hollow-shaped box which has a rear wall 232, a front wall 234, a top wall 236, a side wall 238 and a rear wall extension 24o. The edges of the side wall bind arcuate so as to form the leading edge 36 au. The front surface of the rear wall extension 24o is immediately behind the rear surface of the lower end plate 222 of the transport roller. A curved guide finger 242 is mounted on a torsion bar 244 that is supported by and between the front and rear side plates 238 and 232 . A spring 246 tensions the finger from the transport roller wag. The guide edges 36 and the inner side of the guide unit are arranged concentrically to the transport roller.

252 of the horizontally running tracer 262 attached. If, each transport roller 38 is transported transversely across the Hauptplattenanordnimg the Ώlederreihen 178, the buttons detect in succession the lower lever of the cutout 226 similar to gear teeth and cause the T _r ansportrolle rotates around the shaft 2O6.

It should be noted that the bonds of the links 178 go along between the rear guide surfaces 64 and 66 and the front guide surfaces 6fi and 7o, that is, around the return guides without any guidance. This is achieved by 1.) The distance between the Center lines of the üenach- g

"toarten link pins 194 is made equal to the distance between the center lines of the rear guide surfaces 64 and 66 and the front guide surfaces 68 and Jo , and by 2.) the drive devices meshing, ie the transport roller 72 and / or 7-1 engages The dynamic properties of the linkage during rotation are such that the center of gravity of the link decelerates in a uniform manner, and then accelerates in a uniform manner. The path of the center of gravity forms a true semicircle. The limb also rotates about its center of gravity, so the limb is under control both geometrically and dynamically.

The buttons 248 next to the front and rear arrangements of the rows of links 178 serve to synchronize the rotation of the transport rollers thereon. The transport rollers, however, swing away from the horizontal beam as they pass around the return guides. In order to maintain synchronization of the rotation of the transport roller between the front and rear assemblies, a left cam plate and a right cam plate 2 are fixed to the ends of the beam, respectively. When a cut-out 226 of the lower transport roller plate leaves the last button next to an arrangement, the knuckle of the wü] btcri hjnherbuiigc.n 23o in the unl "r (; ri plate of the transport roller when walking around the .iüek guide der ',' mil-cnplnttc 2b4 and;?

Although an even number of limbs 178 was shown, so an odd number can also be used, furthermore Although a question roller and a combination of bars have been shown here, a rack can be arranged on each link be, and driven by a gear.

The conveyor 14 is similar to that described in UB Patent No. 3,429,221 dated February 25, 196y. Briefly, the assembly consists of a series of links 26o, each link including a web 42, a left hinge 264s, two right hinges 266, a front guide dog 268 and a rear guide dog 27o. adjacent Gelerike are coupled by a pin 272 which ^rt eihen of the members are guided on and around a folded guide plate 274, in which a front Führungseinkerbung 276 and a rear Führungseinkerbung is formed 278 to the voredren driver 268, and accordingly, the rear carrier 27o of a to include every link. Left transport roller 272 and right transport roller 274 are attached to respective shafts 88 and 9o, and are located between and extend through the upper and lower folds of the guide plate. The teeth of the transport rollers grip the row between adjacent webs in order to drive them. An outer guide plate extends from the right end of the main plate, around the right return and under the row of links to the left. The feed device continues to the left, however, as is not shown further, to the weapon that is to be loaded.

For operation, each of the channels 16 will be the same Number of cartridges filled. Each cartridge is held in the channel by the lips 48, that of the cartridge eye disc 49, as shown in Figure 7, are adapted. The lower In each row, the Mihrunga cartridges rest on the top ■
