Abstract

21,470. Schmitz, J. Oct. 6. Work-holding devices.-Bases a bolted to the machine table carry nuts d which are received into recesses in blocks b sliding on dovetailed projections on the bases. The blocks have dovetailed grooves which receive sliding jaws raised when free by spring pins g. Screws i engage slots in the jaws and prevent the latter from leaving the grooves in the blocks. Lefthanded screws f secured in the blocks work in hollow screws e in right-handed nuts d, and give the blocks a double travel to compensate for the movement of the jaws. The gripping-faces of the jaws are provided with intersecting horizontal and vertical grooves to enable them to secure convex work.
