摘要： To feed cartridges from a drum-type or drum magazine to a firing weapon a first conveyor is required to push the cartridges out from the drum-type magazine in which the cartridges are arranged in a number of rows. A second conveyor feeds the cartridges which have been ejected from the drum-type magazine to the firing weapon. At high firing rates as required in multi-barrel guns or weapon systems difficulties can occur in the transfer of the cartridges from the first conveyor to the second conveyor and during the acceleration of the rows of cartridges in the drum-type magazine. According to the invention return or reverse movement blocking devices are arranged between the two conveyors and the first conveyor comprises a screw or worm conveyor having a first turn of the thread which is of smaller pitch than the remaining turns of the thread to facilitate the acceleration of the rows of the cartridges which are initially at standstill in the drum-type magazine.

摘要： 1466681 Feed mechanisms GENERAL ELECTRIC CO 5 July 1974 [17 July 1973] 29915/74 Heading F3C An article storage and feed system comprises laterally spaced-apart channels 14, Fig. 3, each channel having a number of articles such as cartridges therein, first means for concurrently engaging each of the number of articles in any one of the channels and for sequentially extracting a train of the articles of uniform pitch, second means, coupled to the first means, for translating the first means to each of a number of extraction stations in sequence, each of the latter being adjacent a respective one of the channels, and control means, coupled to the second means, for automatically actuating the second means. The channels 14 are stationary. The control means counts the number of extraction operations per channel of the first means. Each channel 14 has means for precluding transverse movement of the stored articles and for permitting longitudinal movement thereof. The first means is a shaft 56, Figs. 1 and 2, having a helical flute which, when the shaft is rotated, translates the engaged articles. The second means includes travelling supports 52, 54, Fig. 3, which support the shaft 56 also transverse supports which carry the supports 52, 54 along a path which is transverse to the longitudinal axis of the channels. The transverse supports comprise spaced-apart shafts 28, 32, each of the latter having a helical cam track with a cycle equal to the space between adjacent channels 14. Each cycle has successive portions of rapid advance, no advance and rapid advance. The supports 52, 54 each have a cam follower 60, Fig. 2, engaging the respective helical cam track. Rotation of the shafts 28, 32 effects transverse translation of the supports 52, 54 and, consequently, the shaft 56. A screw-threaded shaft 50, Figs. 1 and 3, is rotated about an axis which is transverse to the channels 14 by a counter and drive system 40 and drives the shaft 56 via a gear 72. A sprocket is carried by the supports 52, 54 for receiving articles in sequence as extracted by the shaft 56. A movable endless chain of geneva elements receives articles in sequence from the sprocket. The output of the geneva elements is coupled to the second means which comprises the travelling supports 52, 54 and the shafts 28, 32 and the input to the geneva elements is synchronized with the shaft 56. The articles may each be provided with a "T"-shaped projection which is received in a "T"-shaped transverse opening in the channel 14. In another embodiment a first shaft, having a helical flute, is movable transversely and feeds a second shaft, having a helical flute, which, in turn, feeds an endless conveyer chain.

摘要： 572,504. Cartridge magazines. MOTLEY, L. Aug. 4. 1939, Nos. 22652 and 22653. [Class 92 (ii)] Relates to cartridge magazines for automatic guns of the kind having a plurality of cartridge compartments 2, Fig. 5, and conveyer means 11 at one end of the compartments for feeding the rounds to the gun. According to the invention, the rounds 1 in each compartment are permanently pressed towards the conveyer as by means of spring-pressed rollers 6, and the compartments are provided with movable traps or stops 8 to withhold the rounds from the conveyer so long as there are any rounds in the preceding compartment and to move automatically to the open position when the preceding compartment is exhausted. The invention is shown applied to a magazine having a worm conveyer 11 feeding to the right, as described in Specification 572,510, the cartridges being pressed towards the conveyer by rollers 6 on spring-loaded arms 4 as described in Specification 572,505. The stops 8 shown are in the form of spring plates 9 held in operative position by the cartridges themselves, but springing to the inoperative position shown to the left of Fig. 5 when the compartment is exhausted. The compartments are formed of separate trough-shaped elements nested together, as shown in Fig. 4.

摘要： 185,900. Vollmer, H. July 7, 1921. Machine guns.-Relates to feed mechanism for guns of the type in which the cartridges or projectiles p are conveyed to the breech by a wire or like worm d arranged on a rotary shaft c at the outlet of a magazine h. According to the invention, the magazine is a substantially semicylindrical chamber having a slot through which the feed-worm protrudes and containing a hinged vane k acted upon by a spring q which sweeps the cartridges or projectiles on to the feed-worm. The curved wall of the magazine has an aperture o closed by a sliding shutter i.
