Abstract
The present invention relates to improvements in firing and cocking mechanism of a breach loading firearm. This invention utilizes a substantially massive pin block disposed in a horizontal track between two counter biasing springs, the main spring and the counter spring. A firing pin extends from the chamber end of the pin block. When the cocked pin block is released, the main spring drives it toward the chamber and the momentum of the moving pin block carries the extended firing into contact with the primer of the cartridge despite the resistance of the counter spring. Lowering the breechblock allows a spring loaded ejector plate to spring backward and pull the spent cartridge casing from the chamber. In addition the ejector plate strikes a projection of the pin block and drives the pin block back to the cocked position. An extension of a lever which operates the action returns the ejector plate to the chamber so that the breechblock is able to rise unobstructed. Lost motion pivots connecting this lever to the breechblock provide the timing whereby one return stroke of the lever sequentially seats the ejector and raises the breechblock. The trigger release mechanism for this firearm is simply constructed from a very limited number of ruggedly manufactured parts.
