Patent ID: 6905116

Claim:
A toggle clamp comprising: a compression spindle assembly comprising: a plunger and a spindle, the plunger having a chamber dimensioned to slidingly receive the spindle in a telescoping arrangement, and a resilient member disposed in the plunger chamber to urge the spindle away from the plunger chamber; and a screw extending through a bore of the spindle and the plunger chamber and threaded into the plunger to maintain the spindle in sliding contact with the plunger chamber, the screw having a head abutting a shoulder monolithically formed in the spindle bore, the screw being rotatable to adjust a level of compression of the resilient member such that the compression spindle assembly reliably applies a gradual rate of pressure as the compression spindle assembly is compressed, the spindle bore being configured to allow longitudinal movement of the screw head away from the shoulder when the compression spindle assembly is compressed; and a lever linkage being operatively connected to the compression spindle assembly to move the compression spindle assembly into and out of contact with a work piece.
