ABSTRACT:
Lock construction for the hammer of bulletbore firearms of foldable construction. The invention prevents the rearward movement, of the striker by the effect of the pressures of the gases from the gunpowder on firing of the arm, and also the ending up of the detonator material into the striker hole. The lock construction comprises a support fork, fitted in connection with a spindle of a folding lock of the arm, the said support fork being, in connection with the firing of the arm, shifted by the force of a spring to a hammer locking position. In this locking position the support fork rests against the hammer and, locks it in its forward position and thereby prevents the striker pin from being shifted rearwards by the force of the gunpowder gases. When the arm is being folded, owing to a camming arrangement between the spindle and the support fork, the support fork pivots to a hammer unlocking position so that the hammer can be cocked.
