Trigger device for automatic gun

A trigger device for an automatic gun having a firing direction, comprising a receiver, a trigger guard mounted in said receiver, a trigger pivotally attached to said trigger guard and arranged to be pulled by a shooter for firing the gun, a breech block mounted in said receiver upwardly from and forwardly of said trigger relative to the firing direction, a connector which is elongated in the firing direction and has a forward end portion extending in the firing direction forwardly of said trigger and a rear end portion positioned above said trigger, said forward end portion having a downwardly extending leg portion, said trigger having an upper part adjacent said rear end portion of said connector, said rear end portion being mounted to said upper part of said trigger for pivotal movement about an axis transverse to the firing direction wherein said connector is moved in the firing direction when said trigger is pulled to pivot relative to said trigger guard to move said upper part of said trigger, a sear rotatively attached to said trigger guard forwardly of said trigger in the firing direction, a spring for biasing said sear for rotation in the direction opposite to the firing direction, said sear having an upwardly extending edge facing rearwardly toward said trigger and first and second upwardly directed faces, said first face being located above said second face, said forward end portion of said connector being in juxtaposition to said upwardly extending edge so that said connector pivots said sear against the biasing action of said spring when said trigger is pulled, said sear having a claw part facing opposite to the firing direction, a hammer pivotally attached to said trigger guard forwardly of said sear and extending rearwardly from the pivot point to adjacent said sear, said hammer having a hook part on the end thereof spaced rearwardly from the pivotal connection and arranged to interengage with said claw part of said sear for holding said hammer in position to fire the gun and said hammer being releasable from said sear when said sear is displaced against the biasing action of said spring associated therewith by said connector, a spring loaded within said trigger guard and bearing against said hammer for pivotally displacing said hammer forwardly in the firing direction when the interengagement of said sear and said hammer is released, a spring mounted on said trigger rearwardly in the firing direction from the pivotal connection of said trigger to said trigger guard, said spring mounted on said trigger extending upwardly into contact with said connector and biasing said connector downwardly against said first upwardly directed face on said sear so that a preset gap is provided between the free end of said leg portion and said second upwardly directed face on said sear, said breech block being slidably displaceable through said receiver when the gun is fired so that said breech block returns said hammer from the released position back into the interengaged position with said sear, said second upwardly directed face on said sear being moved through said gap and against the free end of said leg portion to upwardly displace said forward end portion of said connector thereby disengaging said sear so that said forward end portion of said connector is unable to contact said sear for effecting firing of the gun.
