Enclosed is a self-powered telescoped ammunition revolver gun, including a frame which mounts a revolver cylinder having circumferentially spaced chambers and a cylindrical exterior surface on which is formed at least two U-shaped open cam channels, each having forward facing open entrance and exit ends spaced apart by the same angular distance as the chambers. First and second elongated drive cylinders extend forward from the frame on separate axes disposed outboard of the revolver cylinder and circumferentially spaced apart by their same angular distance as the chambers. Each drive cylinder mounts a spring loaded operating rod having a gas piston at its forward end and an exposed cam driver/follower proximate its rear end for successively engaging the U-shaped open cam channels to rotate the revolver cylinder and drive the gun as the rod reciprocates linearly in its drive cylinder. Gas channeling and diverting means is coupled between the gun barrel and the forward ends of the drive cylinders for tapping gas from the barrel bore and alternately directing the gas to the first and second drive cylinders responsive to the firing of successive rounds and to the rotary position of the revolver cylinder.

A self-powered automatic revolver gun for firing cylindrically cased telescoped ammunition rounds at a high rate of fire, said gun comprising: (a) a gun frame having top, bottom, and opposite lateral sides and having forward and rear ends: (b) a revolver cylinder, having an even plurality of at leas
A self-powered automatic revolver gun for firing cylindrically cased telescoped ammunition rounds at a high rate of fire, said gun comprising: (a) a gun frame having top, bottom, and opposite lateral sides and having forward and rear ends: (b) a revolver cylinder, having an even plurality of at least four cylindrical ammunition chambers; (c) a gun barrel mounted to and extending forward from said gun frame, said gun barrel having forward and rear ends, a longitudinal axis, and a bore centered on and extending along said longitudinal axis of the gun barrel; (d) said gun frame having a breech region disposed rearwardly of and adjacent the rear end of the gun barrel for mounting the revolver cylinder, an ammunition receiver region disposed rearwardly of and adjacent the breech region, and a spent ammunition case receiving and ejection region disposed forward of and adjacent the breech region; (e) the revolver cylinder having a central longitudinal axis, a substantially cylindrical exterior surface disposed coaxially therewith, arid rear and forward end faces, with said plurality of cylindrical chambers extending longitudinally through the revolver cylinder and its end faces on axes parallel to, and disposed at uniformly spaced loci arranged in a circular array centered on said central longitudinal axis of the revolver cylinder with said loci being evenly spaced a predetermined angular distance apart to together encompass 360°; (f) means rotatably mounting the revolver cylinder in the breech region of the gun frame for rotation about its central longitudinal axis, with the front end face of the revolver cylinder disposed adjacent the rear end of the gun barrel and with the central longitudinal axis of the revolver cylinder disposed parallel to but offset from the gun barrel axis by the radius of said circular array of revolver chamber loci, whereby rotation of the revolver cylinder brings said axes of the cylindrical chambers of the revolver cylinder successively into coaxial registration with the axis of the gun barrel; (g) means for triggering the gun to fire; (h) firing means responsive to the triggering means for firing an ammunition round contained in the chamber of the revolver cylinder in coaxial registration with the gun barrel; (i) at least two substantially U-shaped open cam channels similarly formed on the exterior cylindrical surface of the revolver cylinder respectively at successive circumferentially spaced apart locations, with the bend of each U-shaped cam channel disposed proximate the rear end face of the revolver cylinder, and with the respective legs of each U-shaped cam channel extending forwardly on said exterior cylindrical surface and through the periphery of the front end face of the revolver cylinder for providing respectively open entrance and exit ends for each U-shaped cam channel at the periphery of the forward end face of the revolver cylinder; (j) the open entrance and exit ends for each U-shaped cam channel being circumferentially spaced apart at the forward end face of the revolver cylinder by the same predetermined angular distance by which the axes of the revolver cylinder chambers are spaced, with the exit end of each U-shaped cam channel being spaced apart from the entrance end to the circumferentially successive U-shaped cam channel by the same predetermined angular distance, and with the sum of the angular distances as thus stated between said entrance and exit ends for each U-shaped cam channel and between successive U-shaped cam channels adding to 360°; (k) gun drive means mounted to said gun frame and extending forwardly therefrom alongside the gun barrel and responsive to the firing of successive ammunition rounds for successively driving said revolver cylinder through said predetermined angular distance in the same rotary direction, upon firing of each successive ammunition round, said gun drive means including: (i) first and second elongated drive cylinders mounted to said gun frame and extending forwardly therefrom alongside said barrel on separate axes, said separate axes being disposed parallel to the barrel axis outboard of the exterior cylindrical surface of the revolver cylinder, and said separate axes being circumferentially spaced apart respecting the revolver cylinder by said predetermined angular distance; (ii) first and second elongated operating rods respectively mounted in the first and second drive cylinders, and restricted to linear, non-rotary reciprical rearward and forward movement therein between a rear position and a forward or rest position; (iii) each operating rod having a gas piston formed proximate the forward end thereof and having a cam driver/follower mounted thereon proximate the rearward end thereof, said cam driver/follower being exposed exteriorly of the drive cylinder and extending inwardly from the operating rod toward the circumference of the revolver cylinder in alignment, with the exterior cylindrical surface thereof for successively entering aligned entrance ends of said U-shaped cam channels and exiting the exit ends tbereof as the revolver cylinder rotates and the operating rod reciprocates; (iv) means spring loading the operating rods toward their forward rest positions; (v) each cam driver/follower being disposed a spaced distance forward of the front end face of the revolver cylinder when the associated operating rod is in its forward or rest position: and, (vi) gas channeling and diverting means coupled between the barrel and forward end portions of the first and second drive cylinders, and responsive to the firing of successive ammunition rounds and to the rotary position of the revolver cylinder for tapping gas from the barrel bore and alternately directing successive gas to the first and to the second drive cylinders to alternately drive the first and second operating rods rearwardly so as to drive the associated cam driver/follower into an aligned entrance end of an aligned U-shaped cam channel, and in turn rotate the revolver cylinder through said predetermined angular distance as the cam driver/follower traverses the aligned U-shaped cam channel and emerges from the exit end thereof; (l) indexing means, responsive to the position of the operating rods and the revolver cylinder, for unlocking and locking the revolver cylinder from rotation between firing of successive ammunition rounds. (m) ammunition receiver and rancher means mounted on the gun frame in the ammunition receiver region thereof and responsive to rotation of the revolver cylinder for receiving fresh cylindrically cased ammunition rounds and progressively ramming a fresh cylindrically cased ammunition round into each revolver chamber following firing of the round contained therein while progressively pushing forward and out of the same revolver chamber the spent cylindrical case of the fired round; and, (n) spent case receiving and ejection means mounted on the gun frame in the spent ammunition case receiving and ejection region thereof and responsive to rotation of the revolver cylinder for receiving spent ammunition cases as they progressively emerge from the successive revolver chambers and for ejecting fully emerged cases from the gun.
