1 Claim. (Cl. â9-27)
The invention relates to a repeater-type cocking firing
along forwardly when the tension of the spring is relaxed.
This cap-like sleeve moreover has an outwardly directed
ñanged rim which serves as an abutment tor the spring.
Owing to the use of only a single spring, the repeater
type cocking tiring mechanism according to the inven
tion 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 accommodat
10 ing a return spring is saved. Moreover, this firing mech
mechanism for firearms, more Vparticularly guns, having
anism can be fitted in breeches having very small cross
sections. Y Apart from a recess Yfor the ñringnmechanism,
a striker adapted to be retracted into the cocked position Y
only an outwardly leading bore for the ñring spindle is
by means of a firing spindle or the like and flying for
also required in the breech. In addition to this, the ñr
ing mechanism according to the invention forms a self
contained structural unit which can be fitted and removed
ward into the operative position on firing through spring
force. The invention differs from the constructions here
tofore known above all in that the cocking and release of
the striker and the return thereof to the inoperative posi
tion is obtained with a single spring, the firing mechanism,
as one whole.
Details of the invention will appear from the follow
ing description of the embodiment illustrated in the
