ABSTRACT:
A toggle clamp comprises a compression spindle assembly with a plunger and a spindle. The plunger has 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. A screw extends through a bore of the spindle and the plunger chamber and is threaded into the plunger to bias the resilient member and maintain the spindle in sliding contact with the plunger chamber. The screw has a head abutting a shoulder monolithically formed in the spindle bore. The screw is rotatable to adjust a level of compression of the resilient member. The compression spindle assembly reliably applies a gradual rate of pressure as the compression spindle assembly is compressed.
