Definitions

  • Patented Uct. is, 1921.
  • This invention relates to improvements in machine 7 safety devices to revent the loading of magazines intended for practice or other training purposes, with ball cartridges, and also to facilitate the movement of the cartridges within the magazine when loading or firing.
  • the object is to provide a simple, durable and inexpensive attachment to be applied to a modern machine gun magazine that will not only aid in the movement of cartridges in the magazine, but will positively prevent the insertion of a ball cartridge into a magazine intended for blank cartridges.
  • a further object being to provide a construction wherein a slight modification of the attachment will permit the insertion of ball cartridges or make the device applicable to the regular service magazine, and still continue to possess the means whereby the cartridges are freely fed in either direction in the magazine.
  • Figure 1 is an inverted plan view of the magazine of a machine gun showing the safety and guide plate in plan view.
  • Fig. 2 is a vertical section taken on line 2-2 of Fig. 1.
  • Fig. 3 is a detail edge view of the safety plate.
  • Fig. 4 is a view similar to Fig. 1, showing a slightly modified form of safety and guide late.
  • p Fig. 5 is a section on line 55 of Fig. 4.
  • numerals 10 indicates the magazine pan of a modern machine gun, and 11 the spacer ring in which are mounted the separator-pins 12.
  • the magazine-center 13 is provided with the usual helical groove 14 for the reception of the noses of the cartridges, and is inside of the separator-pins 12.
  • the magazinecenter remains fixed while the pan rotates.
  • the magazine-pan rotates, it carries with it the interior separator-pins 12 and the cartridges, and the center 13 being held stationary the cartridges guided by the groove 14- in the magazine-center are moved toward or from the feed-way 15 in the usual manner.
  • the magazine rim clips 16 are attached to the inner face of the magazine- 'pan and form guides for the heads of the cartridges.
  • the magazine In loading, the magazine is turned upside down and in a well known manner the mag- -azinecenter is held by the left hand and a cartridge dropped into its place with the nose of the cartridge in the feed-way or entrance to the magazine-center and its rim engaged by the rim clips.
  • a loading machine performs the above very rapidly by mechanical means, the cartridges being fed from a chute.
  • the magazine is shown in its loading position or inverted for reception of the cartridges, Fig. l for blank cartridges and Fig. 4 for ball I cartridges.
  • the improved safety and guide attachment consists of a circular plate 20 secured by hollow rivets 21 or other suitable securing means to the magazine-center 13.
  • the plate 20 is provided with a bead 22 near its outer edge and is cut away at 23 in line with the feed-way 15, the depth of Said cut-away portion determining the type of cartridges that may be inserted into the magazine.
  • the plate is bent inwardly and tapered to provide a lip 24 of such shape as to snugly fit across the feedway and diminish its length to such an extent that other than a blank cartridge, cannot be inserted or fed into the magazine.
  • the plate 20 is considerably larger in diameter than the magazine-center and overhangs its edge, thereby forming a guide and support for the cartridges beyond said center.
  • Figs. 4 and 5 a slightly modifiedform of plate 25 as above referred to, is shown where the cut-away portion 26 is deeper than the cut-away portion in the preferred form of plate, thus permitting the insertion of ball cartridges.
  • a safety and guide attachment for machine gun magazines of the drum type consisting of a plate adapted to partly cover the feed-way, and a li carriedby the plate resting across the fee -way.
  • a safety and guide attachment for machine gun magazines of the drum type consisting of a plate mounted on the magazine center, having a cut-away portion in line with the feed-Way, and a lip extending from one end of the cut-away portion across the feed-Way.
  • a safety device for use in loading machine gun magazines of the drum type consisting of a plate adapted 'to be'placed on the magazine-center, a cut-away portion adapted to register with the feed-way, and a depending lip adapted to diminish the length of the feed-way and prevent the entrance of a ball cartridge.
  • a, plate used in loading machine gun magazines of the drum type having a cut-away portion adapted to rest in line with the feed-way of the magazine, a lip depending from the plate to diminish the length of the feedway, and a guide bead on the plate outside of the peripheral edge of the magazinecenter.
