Definitions

  • the invention relates to a repeater-type cocking firing mechanism for firearms, more Vparticularly guns, having a striker adapted to be retracted into the cocked position Y by means of a firing spindle or the like and flying forward into the operative position on firing through spring force.
  • the invention differs from the constructions heretofore known above all in that the cocking and release of the striker and the return thereof to the inoperative position is obtained with a single spring, the firing mechanism, with the exception of the bore for the firing spindle, being accommodated in a single recess.
  • the spring is arranged between two spring abutments, at least one of which can be shifted towards the other for the purpose of tensioning the spring by actuating the tiring spindle and, on the relaxation of the spring on firing, projects the striker forward rapidly into the Yoperative position.
  • both the spring bearings are arranged on the striker so as to be movable axially towards one another and, for the purpose of tensioning the spring, are moved towards one another by turning the firing spindle in one direction.
  • the firing spindle car-ries the striker back into a cocked position at the same time.
  • the striker has a shoulder referred to as the cocking piece and the firing spindle has two projections, namely a socalled pressure projection and a cocking projection.
  • the cocking projection serves to retract the striker into the cocked position by means of the cocking piece.
  • the striker then shifts the front spring abutment surrounding it towards the rear one, which is moved forwardly by the pressure projection.
  • a cocking latch is rotatable in the cocking piece and the cocking projection presses against said cocking latch during the tensioning of the spring and thereby shifts the cocking piece together with the striker and the front spring abutment into the cocked position.
  • a pressure pin which is axially movable and parallel and eccentric with respect to the longitudinal axis of the striker is provided in the cocking piece for the purpose of turning the cocking latch in front of the cocking projection of the firing spindle when the rear spring abutment strikes against the front end face lof the pressure pin.
  • the pressure pin turns the cocking latch into its inoperative position by means of a projection thereon, whereby a second projection extending from the cocking latch arrives in front of the cocking projection of the firing spindle.
  • This projection then serves to shift the cocking piece together with the striker into the cocked position by means of the cocking projection when the firing mechanism is cocked.
  • the 'Ilse rear abutment for the sole spring takes the form of an annular disc having its surface remote from the spring resting against pins mounted on the pressure piece or raised portions projecting therefrom, for example studs.
  • the front spring abutment is advantageously a cap-like sleeve which has its end or base surface surrounding the striker in the form of a ring resting against an annular shoulder of the striker and thereby carries it 3,095,781 Patented ⁇ luly 2, 1963 along forwardly when the tension of the spring is relaxed.
  • This cap-like sleeve moreover has an outwardly directed anged rim which serves as an abutment tor the spring.
  • the repeatertype cocking tiring mechanism according to the invention has the advantage that operating trouble which otherwise occurs when a plurality of springs is employed is substantially reduced. Furthermore, the relatively large space which is otherwise required for accommodating a return spring is saved. Moreover, this firing mechanism can be fitted in breeches having very small crosssections. Y Apart from a recess Yfor the ringnmechanism, only an outwardly leading bore for the ring spindle is also required in the breech. In addition to this, the ring mechanism according to the invention forms a selfcontained structural unit which can be fitted and removed as one whole.
  • FIGURE 1 shows the repeater-type cocking firing mechanism in the inoperative position, partly in elevation and partly in longitudinal section, together with a part of the breech;
  • FIGURE 2 shows the repeating cocking firing mechanism in the cocked position, partly in longitudinal section and partly in elevation, together with a part of the breech;
  • FIGURE 3 shows the repeating cocking mechanism after ring
  • FIGURE 4 is a view of FIGURE 1 in the direction of the arrow A.
  • cocking piece 6 which is located transversely of the longitudinal axis of the striker 3 and eccentrically with respect thereto and has two projections S, 9. 'Ihe cocking piece moreover contains a pressure pin 10 which is arranged so that it is parallel and eccentric with respect to the longitudinal axis of the striker 3.
  • This pressure pin is supported by its rear end against the projection 8 of the cocking latch 7 and by its front end, in the inoperative position according to FIGURE l, against a disc 13 placed loosely on the pressure piece 14. Owing to this supporting action, the cocking latch 7 is held in the inoperative position.
  • 'I'he disc 13 serves as an abutment for the sole spring 111, which surrounds the striker 3.
  • the other abutment is formed by a cap-like sleeve 12 which is mounted to be axially movable on the striker 3 and has its base engaging behind an annular shoulder on said striker.
  • Said sleeve has a rim widened ⁇ outwardly in the form of a ange or collar and against which the spring ⁇ 11 is supported.
  • the pressure piece y14 rests against the other side of the disc 13 by means of let-in pins 14 or projecting studs, said pressure piece being loosely mounted on the striker 3.
  • a bore 15 in which the firing spindle 16 is rotatably mounted said ring spindle having at its outer end a cocking lever 17 having an eye 18 to which the firing lanyard 19 is attached.
  • a pressure projection 20 and a cocking projection 21 are provided at the other end of the firing spindle 16.
  • a shoulder or surface 22 is provided on the breech i1.
  • said spindle has on its periphery an annular groove 23 in which a retaining pin 24 engages.
  • the cooking lever 17 is drawn in a clockwise direction by pulling on the firing lanyard 19, as shown in FIGURE 1, ,until it strikes against the stop ZZ. ⁇ Owing to the pull, the tiring spindle is turned correspondingly in the bore in the breech 1. In this process, the pressure projection l of said spindle urges the pressure piece 14 to the right, i.e.
  • the spring is tensioned from both ends, namely on the one hand owing to thev fact that the disc '13 is moved to the Iright by the pressure projection 1Z0i and the pressure piece 14 and, lon the other hand, ⁇ owing to the fact that the sleeve 12 is moved to the left by the cooking projection 21, the projection 9, the cooking piece 6 and the striker 3 with its point 4.
  • the tiring spindle 16 is turned back by means of the spring 11 by way of the disc 13, the pressure piece 14 and the pressure projection 20.
  • the returning pressure piece 14 urges the cooking piece 6 to the left, whereby the striker f3 and striker point 4 connected thereto are carried back again to the inoperative position shown in FIGURE l and, owing to the striking of the disc 13 against the pressure pin 10, the cooking latch 7 is turned by means of the latter and theprojection 8 in a counterclockwise direction in its bearing in the cooking piece 6, so that the projection 9 of said cooking latch again arrives in front of the cooking projection 21 of the tiring spindle 16. All the parts of the repeater-type cooking tiring mechanism are now again in the inoperative position. The gun can now be tired again.
  • the repeating iring mechanism may also be employed as an automatic cooking device if the tiring spindle 16 and the cooking latch 7 are exchanged and an additionalv pressure pin is fitted for initiating firing or release.
  • Repeater cooking mechanism for firearms, more particularly guns comprising a breech having a bore therein, a sleeve secured in one end of the bore, a striker slidably mounted in the bore and in the sleeve and having a ring pin at one end thereof, a disc mounted on the striker and sl-idable with respect thereto, a single cornpression spring around the striker abutting against the sleeve at one end and the -disc at the other end, a oooking piece secured on the other end of the striker to be slida-bly movable therewith, a member having a projecting part and a cooking part operative against the disc and the cooking piece, means to operate the member to compress the spring to a cooking position of the striker for the iii-ing position and to force the striker back to its initial inoperative position, a cooking latch rotatably mounted in the cooking piece and having two projections, and a pressure pin provided parallel and eccentric with respect
