Abstract
A load regulator is adjustably mounted in a machine for loading a workpiece and comprises inverted telescoping cup-shaped piston and cylinder elements defining a variable length chamber for a coil spring. Cooperating indicia on the piston and cylinder provide a direct readout scale to indicate the actual load force applied to the workpiece in proportion to the compression of the coil spring.
Claims7
In a machine arrangement for accurately setting the load applied to a workpiece, an improved load regulator mounted to act between the machine and the workpiece for applying a load to the workpiece and comprising cooperating piston and cylinder means defining a variable length chamber, a coil spring disposed in the chamber to react between the piston and cylinder means and change in length in unison therewith for applying a load from the piston means to the workpiece, said piston and cylinder means having cooperating cylinder indicia and piston indicia arranged to indicate the value of the load in proportion to the length of the coil spring, and means to axially adjust the position of the cylinder means relative to the machine in accordance with the value registered by the indicia to set the load applied to the workpiece by the piston means, said cylinder means having external threads engageable with a threaded machine mounting bore to enable axial adjustment of the position of the cylinder means for setting the load to be applied to the workpiece.
