Abstract
A piston overtravel indicator for indicating overtravel of a piston from a rest position adjacent one end of a cylinder to working positions displaced from the rest position toward the other end of the cylinder. The indicator includes an elongated indicator rod slidably extending through a hole in the other end of the cylinder and having an inner rod end located within the cylinder adjacent the working positions of the piston. Overtravel of the piston beyond working positions causes engagement of same with the inner rod end for moving the rod outwardly through the hole. The indicator rod has a circumferential groove adjacent the inner end thereof for cooperation with a yieldable abutment extending into the hole for preventing complete outward displacement of the indicator rod through the hole.
