Definitions

  • the present invention relates to a device for feeding rounds of ammunition from a magazine to the ramming position of a gun, especially a recoiling gun; and more particularly to a device of the general kind above referred to, in which the rounds are successively fed from the magazine to a feeding table which in turn transports the rounds to the ramming position.
  • Another object of the-invention is to provide a novel and improved feeding device inwhich therecoil movement of the gun is utilized to activate the feeding mechanism of the device so that rounds are successively fed to the ramming position until all the compartments are emptied and that any danger of jamming of rounds on the feeding table is effectively avoided.
  • FIG. 1 is a perspective view of a round feeding device according to the invention, parts of the device being cut away to show the interior of the device.
  • FIG. 2 is a diagrammatic elevational front view of the magazine according to FIG. 1, and
  • FIG. 3 is a section taken on line III-III of FIG. 2.
  • the exemplified round feeding device comprises a magazine consisting of two halves 1 and 2. Both halves are fixedly mounted on the breech casing 3 of a recoiling gun, which may be elevated or depressed by conventional means suitable for the purpose and not essential for the understanding of the invention. The only recoiling component of the gun atent gun. All the components shown in the figures constitute part of the elevating mass of the gun.
  • Each half of the magazine is dividedby partition walls in four compartments and each compartment is shown as being designed for receiving four rounds of ammunition. However, as will be evident, the number of cornpartments and the capacity of the compartments may be larger or smaller than shown.
  • Each of the compartments includes an appropriate number of spring loaded pawls 5 which are mounted on a frame 6.
  • the frames are axially movable, that is, longitudinally of the compartments. They are guided by means of rollers 7 in guide tracks 8.
  • the guide tracks 8 mount spring loaded pawls 5 which in a well known manner serve to prevent an upward movement of the rounds in the compartments.
  • the feeding table is mounted below the two halves of the magazine at a right angle thereto. It comprises a transversely movable bar 9 to which are secured two elongated members 10 and 11. Each of these members supports spring-actuated pawls 12. g
  • FIG. 2 further shows the bottom flange 13 of the cartridge casing of a round in the ramming position.
  • the round is rammed by the acceleration of a rammer 14 or" conventional design.
  • the magazine should be emptied starting from the outside compartments relative to the ramming positionand preferably alternately to avoid a jamming of the rounds on the feeding table.
  • guide means in the form of Maltese crosses '15 are provided which retain the rounds on the table parallel to each other and to the, final ramming position, or in other words, at a right angle to the direction of transport on the table.
  • lever 18 will be urged toward the right by its spring device 16, and lever 19 will be urged toward the left by its spring device 17, as seen in FIG. 3.
  • Each lever in its pushed-out position will be in the path of movement of tongue 4 during the recoiloperation, and as a result will be pushed inwardly by engagement with the tongue.
  • the pushed-in position of the lever which is shown in FIG. 3 for lever 18, repwhich is shown is a tongue 4 which should be visualized as being connected to the breech ring (not shown) of the resents the cocked position of the respective spring device and the levers are retained in the pushed-in position by releasable catch noses 22 and '23 respectively.
  • spring device 17 is cooked by pushing lever 19 toword' the right and is retained in its cocked position by reengagement of lever 19 with catch 23.
  • bar 9 is pushed toward the right by the previously cocked spring device 16 when the associated catch 22 is released.
  • alternate recoil movements. of tongue 4 will move bar 9 toward the left and right respectively, thereby causing feeding of rounds alternately" from the right and the left half of the magazine.
  • Suitable and well-known selecting means are provided for controlling the release of catches 22 and 23 in the proper sequence and with the proper timing.
  • the longitudinal displacements of frames 6 which-in turn effect the feeding of successive rounds upon the feeding table, are derived from the rcciprocatory' movements' of the feeding table, or more specifically of the Forthis purposea lever 25 is pivoted at bar 9' thereof. one 'end to bar 9' andat the other end to a cranlc 26- on a shaft 27.
  • This shaft mountsa bevel gear 28 which- Couplings; 32 are slip couplings; that is, couplings which will transmit a limited predetermined torque only from shafts 31 to arms 33.
  • Various couplings or clutches of this kind, such as spring' couplings are well: known in the art..
  • Damping devices 35 of suitable and conventional design are provided to act as shockabsorbers for arms 33 and adaptors 34..
  • a device for feeding rounds of ammunition from These couplings a magazine to the ramming position of a gun comprising, in combination, a magazine including a plurality ofopen ended, parallel compartments, each one of said compartments receiving a plurality of rounds of ammunition, a feeding table mounted below one end of said compartments andlextending substantially normal thereto for feeding rounds.
  • a round feeding frame slidably supported within each one of said compartments for longitudinal movement relative thereto,
  • each one of said frames having a pluralityof longitudinally spaced apart pawls for supporting and releasing the rounds in each. respective compartment, displacement of each said frame in a direction toward said table releasing the lowermost round in each such compartment for feeding upon said table, drive means for imparting reciprocatory motion to each of said frames, control means transmitting said. motion to each such. frame devoid of. a round of ammunition upon said feeding-table: directly beneath each said compartment, said control means including a slip coupling interposed between said drive means in each one of said frames; said magazine comprising two groups of compartments disposed on opposite sides of a ramming position of the gun, and separate drive means and control means for said groups of. com-.
