Definitions

  • Another object of the invention is to provide a novel and improved non-recoiling gun with breech ring and breech block which permits mounting the exhaust funnel on the block without the need of materially increasing the size and weight of the breech ring.
  • Still another object of the invention is to provide a no'vel and improved gun with breech ring and breech block, the total weight of which is not materially increased and which permits a strong and gas tight mounting of the exhaust funnel.
  • a further object of the invention is to provide a novel and improved non-recoiling gun with breech ring and breech block so designed that the exhaust funnel, mo're specifically the exhaust end thereof which has the widest diameter, moves through a longer distance than its front portion when the breech block is moved into the position opening the breech ring.
  • the breech ring can be kept comparatively small and light and yet will accommodate the required wide movement of the breech block.
  • Fig. 1 is a perspective rear end view of a non-recoiling gun according to the invention.
  • Fig. 2 is an elevational view of the rear part of the gun showing a round rammed home and the breech block closed, and
  • Fig. 3 is an elevational view similar to Fig. 2 but showing the breech block open for ramming a round.
  • a breech ring 2 mounts a breech ring 2 to be closed or opened by displacement of a breech block 5 transversely of the axis of the gun barrel.
  • the breech block is in slidable engagement with the breech ring by means of curved guide tracks and shoes 3 and 4 on the breech ring and the breech block respectively.
  • the guide tracks define part of a circular outline and the concave side of the tracks faces the gun barrel.
  • the narrow end of a conically shown exhaust funnel 6 is secured gas tight to the breech block by any suitable means such as riveting or welding.
  • the breech block 5 is moved relative to the breech ring and the axis of the barrel by means of a suitable linkage system shown as including a handle 7 and a lever 8 mounting a roller 8' sliding in a recess 9 of the breech block.
  • a suitable linkage system shown as including a handle 7 and a lever 8 mounting a roller 8' sliding in a recess 9 of the breech block.
  • Figs. 2 and 3 show the arcuate movement performed by the breech block and the funnel when the breech ring 2 is moved from the breech block closing position of Fig. 2 into the open position of Fig. 3 in which a round 10 may be rammed into the barrel.
  • the wide end of funnel 6 moves through a materially greater are than the narrow end of the funnel due to the curvature of the guide tracks and shoes 3 and 4.
  • the short movement of the narrow funnel end together with the breech block relative to a breech ring of about standard size is sufficient to bring the wide end of tunnel 6 out of the ramming path of round 10.
  • a non-recoiling gun comprising, in combination, a gun barrel, a breech ring at one rear end of said barrel, a breech block for opening and closing said breech ring, a powder gas exhaust funnel of expanding diameter secured upon said breech block with its smaller end facing said one end of said barrel, curved guide tracks on said breech ring slidably supporting said breech block for arcuate movement relative to the breech ring transversely to the longitudinal axis of said barrel, said curved guide tracks forming a curved guide path for the breech block lying in a plane substantially parallel to said longitudinal axis of said barrel and directing the wide end of said funnel for arcuate movement through an arc wider than the are through which said narrow end of said funnel is moved in response to arcuate displacement of said breech block relative to said breech ring.
  • a non-recoiling gun comprising, in combination, a gun barrel, a breech ring mounted upon one rear end of said barrel, a breech block supported upon said barrel for opening and closing said breech ring, a powder gas exhaust funnel of expanding diameter secured upon said breech block at its narrow end facing said one end of said barrel, curved guide tracks carried on said breech ring slidably supporting said breech block for arcuate movement relative to said breech ring in a direction transversely of the longitudinal axis of said barrel, and said guide tracks having a concave side facing toward said one end of said barrel.
