A cocking mechanism for use on an air weapon of the type having a piston slidable in a cylinder to compress air into a reservoir comprises a cocking arm 10 pivotally mounted at 12 on the cylinder, a connecting rod 14 pivotally connected at one end 16 to the piston and at the opposite end 18 to a sledge or slide 20 which is slidably movable on the cocking arm against the action of a spring 28 within a range limited by a recess 30 and a block 32, so that the position of the point of pivotal connection 18 varies during the arcuate pivotal movement of the cocking arm to increase the mechanical advantage of the mechanism during the final part of the compression stroke of the piston. <IMAGE> |
