COOK, JAMES." Making and constructing locks for guns, "pistols," &c.

Locks are made with a mainspring coiled round the striker. The drawings show a walking-stick gun. The barrel is fitted to a hollow stock or handle, and the nipple and touch-hole are in the breech in a line with the axis of the barrel. A copper percussion- cap is placed on the nipple, and is struck by a flat striker actuated by a spiral spring contained in a tubular chamber in the stock or handle; the spring is drawn back by hand, and is held by a catch and released by a trigger motion.
