Abstract
An adjustable clamp is provided for sine plates that make use of gage blocks to set the appropriate height and angle. A chain is disposed through a clamp block having two capstans. An adjustable screw bolt wedges the chain against the capstans and can increase or decrease the tension on the chain depending on whether the chain is pulled between the capstans or released. The chain ends are bolted to the bottom plate of the sine plate and hooked over a catch on the upper plate. Increasing the tension in the chain applies pressure between the gage block and the plates of the sine plate to prevent the gage block from being inadvertently displaced. The clamp stabilizes the sine plate so that the workpiece has a stable mounting.
