Abstract
A force multiplying and locking arrangement is disclosed to lock, for example, a cutting tool to a spindle. It comprises main body arranged to be threadably mounted on a spindle, said main body having a pressure ring at its forward aspect mounted to accommodate movement longitudinally of the arrangement and to inhibit movement rotationally of the arrangement. A cavity is defined by said pressure ring and said main body and includes an inclined plane. The cavity has a plurality of spherical balls disposed therein. Said main body is peripherally threaded to accommodate the threadable mounting of a compression ring having, at its forward aspect, a conical inclined plane overlying the cavity and the first mentioned inclined plane. Rotation of the compression ring forces the spherical balls into the cavity engaging the inclined planes and the pressure ring and greatly multiplying the force for locking the device. Reverse rotation of the compression ring releases the locking force.
