Abstract

725,900. Vices. AKTJEBOLAGET SVENSKT RORLAS. Aug. 4, 1953, No. 21491/53. Class 61. Vices in which the jaws are carried by tubes in telescopic engagement with each other are provided with locking and tightening means comprising a sleeve having a wedge-shaped slit and a wedge member in engagement with the said slit, the locking and tightening operation being effected by an axial displacement of the sleeve and wedge relatively to the outer tube. The stationary jaw 2 of a vice is integral with a tubular member 1 which is adapted to be fixed to a table the movable jaw 4 being integral with a tubular member 3 which telescopes in the tube 1. A sleeve comprising two semi-cylindrical sleeve members 15, 16 is expansible into frictional contact with the outer tube bv a wedge 14 which engages a wedge shaped slit in the sleeve, the wedge being displaced longitudinal of the tube 1 by a rod 7 mounted rotatably in the tube 3. The rod has a piston-like head 11 having on one side a helically cut end surface 13 which engages and serves as a guide for the corresponding helical base of the wedge 14. One end of the sleeve 15, 16 is urged into contact with the annular shoulder 12 on the head 11 by a spring 18 which prevents rotation of the sleeve by forcing a conical washer 17 into a counter sink at the other end of the sleeve. In a modified means for preventing rotation of the sleeve, Fig. 6, the sleeve is provided with a washer 22 having locking teeth which engage similar locking teeth on a washer 24 provided with an axially directed lug 25 engaging in a groove 26 in the end of the inner tube 3. The teeth interlock on rotating the rod 7 in a direction to tighten the jaws, but slide relatively to one another on rotation of the rod in the opposite direction to release the jaws. In another modification the washer 22 is dispensed with, integral teeth being provided on the sleeve members.
