Abstract
A stock stop for screw machines and the like for determining bar stock positioning and which is capable of sensing short stock. The stock stop includes a housing affixed to the machine tool having a slidable sleeve in which a threaded stop is adjustably positioned. A spring biases the sleeve and stop toward the advancing bar and the sleeve is displaced to a stop position by the advancing bar stock. Motion multiplying means multiply the sleeve movement upon engagement by the bar stock to actuate a proximity switch indicating proper advancement of the bar stock and permitting continued machine tool operation. As the components of the stock stop are encased and protected against contamination, a high degree of reliability is attained while providing accurate machine tool control with respect to the presence of adequate bar stock for machining.
