Description:
Wilhelm, Parker & Hard - patent attorneys

This invention relates to improvements in securing or clamping devices for the rotatable tool rests of lathes and analogous machine tools, and more particularly to such devices intended for retaining the rotatable compound rest or tool block on the cross slide of the lathe and for clamping the same thereon in its different adjustments. The object of the invention is to provide a securing or clamping device for this purpose, of simple and inexpensive construction, which will detachably secure the two members together, while permitting free rotary adjustment of one member relative to the other, and which can be readily actuated to firmly clamp the adjustable member against the other member to hold it rigidly in different adjusted positions.
