ABSTRACT:
A lens and pattern holder for use with a grinding tool comprising a rotary grinding ring mounted in coaxial relationship with respect to a grinding ring of the same diameter. The holder comprises a solid body having a pair of opposite surfaces spaced apart so that the peripheries thereof respectively face the grinding and guiding rings of the tool. A pair of pins projects upwardly from one of the opposite surfaces of the body for detachably connecting thereto a pattern having a peripheral edge extending away from the periphery of the one surface. Another pair of pins or a sticking pad is provided on the other opposite surface of the body for detachably mounting thereon another pattern or a lens, respectively. Visible dots are also provided on the one surface of the body for properly positioning and aligning the lens with respect to the pattern connected to the opposite surface of this body. In use, a finishing lens mounted on the other surface of the body can be used as a guide for shaping and finishing the peripheral edge of a blank pattern connected to the one surface of the body. Alternatively, a finished pattern mounted on the one surface of the body can be used as a guide for shaping and finishing the peripherical edge of a lens or of a blank pattern.
