7 mechanism but it is particularly adapted in the case of automatic quick firing fire-arms in which the rebound frequently results in faulty working and may even cause accidents.
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.
The invention has been illustrated dia grammatically and purely by way of example in the accompanying drawing,
7 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.
In this drawing, the piston 1 of themechanism of a quick firing automatic fire-arm, op-
l iofthe mechanism, at theend. of its stroke.
.' Probably, 'owingstothe resilience ofthe ma: vterialathe resultant violent impact causes-the "PlSliOl'l-tO rebound, that is to say, to move me'arwards lw-hereby, in'the .case ofiquick- --'fi-rers,:a number of incidents may occur, t"h11S percussion mayf'be prevented or a partial unlockmg produced,.in'the case'eof aliangfire for example.
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. When the piston accomplishes its normal displacement in either direction, said hammer-piecemoves vwith it. But when, towards the end'of the forward stroke of the piston, the said impact occurs, 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 weight and stroke of the hammerpiece 6 as also the strength ofthe spring 7' must be calculated by duly allowing for the weight and speed of the piston.
In Fig. 2, the cocking-piece 8 and its spring with-respect to the piston 1.
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. Similarly, not only'may 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
Still more generally, 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.
It will, of course, be understood that the invention has only been described in a purely 5 explanatory butby no means limitative manner and that it may be subjected to various modifications of detail Without departing from the spirit thereof.
Iclaim: 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. its displacement in said recess after-said displaceable member-has been suddenly "arrested, whereby said l1ammer-piece Will strike against the front end ofsaid recess to prevent the displaceable member from rebounding as a result of the blow caused by its being suddenly arrested by the fixed member of the mechanism.
