Beschreibung:

5" overall length. This patent relates to the novel and peculiar construction of the breechblock and a rotating cam which form an extension of the breech block trunnion, the said trunnion and cam having an axial movement on a shaft centered between brackets laterally projecting from the right side of the gun barrel, the trunnion having in addition, a longitudinal movement upon its shaft to compel the rotation of the cam in opening the breech chamber. In the periphery of the cam is a spiral groove , which with engages a lateral stud on a retractor, the trunnion having a cam in its base and a latch-bolt on its face , which causes it to engage with the cam in such a manner that in opening the breechblock the retractor is drawn back from the bore, while it is free to move forward on the insertion of a cartridge in the breech chamber and barrel, the whole being more particularly designed as an improvement upon the well known Snyder system. Condition: Very good.
