Abstract: A safety locking switch that can connect a selected wire to a grounded plate, on which the switch is mounted, has a metallic housing, a key operated lock mounted in the housing, an insulator affixed to the housing and an electrical lead extending through the insulator into the housing. In the locked position, the lock is in contact with both the electrical lead and the housing thereby grounding the selected wire connected to the lead. When unlocked by the key, the lock moves away from the end of the lead within the housing thereby open circuiting the path between the grounded plate and the selected wire.

Abstract: An improved bolt mechanism for use in a rotary lock has a fixed transverse pin and a spring biased movable transverse pin. The movable pin may be retracted within the body of the bolt under the action of a key inserted into the lock. The protrusion mechanism comprises a shaft inside the bolt a portion of which is conical. A conical member is likewise attached to the spring biased transverse pin cooperating with the conical member of the shaft thereby allowing the external end of the transverse pin to be moved flush with the external surface of the bolt or to extend transversely therefrom. When the movable pin extends transversely from the bolt, the bolt is retained between key plates in the lock. When the movable pin is retracted, the bolt may be moved longitudinally along its axis through the key plates to unlock the lock.

Abstract: A piston ring honing machine and method are disclosed wherein a stack of piston rings are face finished simultaneously by compressing the rings radially inwardly and into a generally circular configuration and retaining the outside diameter of that circular configuration by confining the compressed rings within a plurality of cylindrical drive rollers disposed about the rings. A honing tool is placed against the ring faces and the rings driven to rotate about the circle center by rotation of one or more of the cylindrical rollers. The stack of rings therefore moves relative to the honing tool to finish the ring face. The tool may be reciprocated in the direction of the cylindrical roller axes to more uniformly finish the ring faces.
