Definitions

  • the invention broadly consists in fitting-a hammer piece to the member whose rebound it is desired to reduce, said hammer piece moving with the member when said member elfects its normal travel in the mechanism, but continuing its movement when said member is suddenly stopped by an impactwith another part of the mechanism and striking said member in the opposite direc tion to that in which the rebound tends to be produced, thus considerably reducing the rebound, and even completely eliminating it.
  • Said hammer piece can be made advantageously in the form of a slide-block lodged in a recess of the; moving member in such a manner that it can accomplish a predetermined stroke, saidside-block being held in its idle position by a spring and striking wherein the end of the recess when said member is suddenly brought to a standstill.
  • Fig. 1 is a diagrammatic view in longitudinal section of the device according to the invention.
  • Fig. 2 is an assembly view showlng the device fitted to an automatic fire-arm.
  • the presentinvention which provides a emeansdon-considerably reducing and even completelyv eliminating the rebound, consists 1n housing in a recess 5 in said piston, a
  • hammempiece76' whichlcanaccomplish a pre- 2 determined stroke within said recess.
  • the hammer-piece 6 is held in the position shown in the drawing by a spring 7.
  • said hammer-piece moves vwith it.
  • the hammer-piece 6 continues its for ward movement in the direction of the arrow 3 and, just as the rebound of the piston is about to occur, strikes the end 5 of the recess 5,'thus giving the piston 1 a blow in the opposite direction to that of the rebound, which will thus be considerably reduced.
  • the hammer-piece may have any shape and any method of fitting the same to the ;;3)-1'its1sh0ulder 4 strikes against a fixed part piston may be used, said hammer-piece'dif fering in both these respects from the example given above.
  • the invention be applied to the piston but also to all the other moving partsof a quickfirer mechanism, actuated by the explosion gases, or of any other type. 1
  • the invention may be advantageously applied to any mechanism having parts moving at high speed and sub- 9 have been shown in their relative positions "8 jected to impacts which may cause a'rebound 1100 liable to produce defective operation of said mechanism.
  • V 1 In a device for reducing the rebound of a displaceable member of a high speed mechanism after impact with another, fixed member of said mechanism, the combination of a hammer-piece received in a recess oi said displaceable member and capable of displacement in said recess, and a spring bearingagainst the end of an opening formed in said hammer-piece and against one end of said I recess, said spring serving to hold thehammerpiece at the rear of the recess, but allowing said hammer-piece to continue.
