Abstract

106,882. Jamart, P., and Dunford & Elliott. June 22, 1916 Breech actions, sliding breechblock; stocks; firing-appliances.- Relates to the trigger-mechanism and to the extractor of bolt-action rifles. According to the invention, the trigger acts directly on the firing- pin, it also serves as the bolt-stop and is maintained in position solely by its spring. The extractor slides in a groove in the breech-body and, at the iront, is constructed to form part of, and complete, the firing-chamber when the breech is closed. In the construction shown in Figs. 2 and 10, the trigger H is formed with a lug 38 which engages the shoulder 37, Fig. 10, on the firing-pin and also forms the bolt-step. The trigger projects through a slot in the breech body and is held in place by a leaf-spring J. The breech-bolt D is rotated and retracted by means of a knurled knob 35 instead of by the usual lever. The barrel is secured to the stock by a single screw 44 having a knurled head. The extractor, Figs. 4 and 5, is separate from the breech-bolt and comprises a stem 21 sliding in a groove in the breech-body and a semi-circular end 22, which fits a recess 23, Fig. 2, in the barrel and completes the chamber. At the rear of the stem 21 is a projection 47 which is engaged by a shoulder on the breech-bolt during the retraction of the bolt.
