Abstract

743,816. CLamps; vices. HAMPTON, Ltd., C. & J. Sept, 3, 1954 [Sept. 5, 1953], No. 24608/53. Class 61. In a clamping device in which the sliding jaw 7 is urged towards the fixed jaw 3 against the action of a spring 12 by a cam 22 carried by a lever 25 pivoted at 24 to the end of the spindle 9 which is rotatable in the sliding jaw 7, means including a plunger are provided for locking the spindle and cam lever to the sliding jaw in various angular positions of adjustment of the cam lever to the axis of the spindle. As shown, the end 27 of the spindle is screwed into a tapped hole 10 in the fixed jaw 3 to allow adjustment of the jaws. The forward end 13 of the spindle carries a rotatable sleeve 14 having radial notches 15 for selective engagement by a projection depending from a plate 17 slidable in a shallow vertical slot in the sliding jaw 7. The plate 17 is locked to the jaw with the projection in position in the selected notch, by a screw 20. A pair of cam plates 22 pivoted at 24 to the flattened head 23 of the spindle 9 fit into a slot 21 in the sleeve 14, so that the cam plates, the sleeve and the spindle may be rotated together. The sliding jaw 7 is supported on a ledge 6 on the base 1, an adjustable pin. 28 carrying a collar 31 maintaining the inner face in vertical position. A protecting rubber muff 32 surrounds the sleeve and projects beyond it. In a modification the plate 17 and projection are replaced by a pair of soring plungers which .engage a selected pair of eight conical recesses provided in the sleeve. In another modification the conical recesses are replaced bv V-notches. Specification 743,815 is referred to.
