ABSTRACT:
A holder for suspending ophthalmic lenses and lens blocks of various diameters from a rod in a lens and block cleaning machine has a frame with a horizontal base member and a pair of upright members extending upwardly, one from each end of the base member. A hanger extending from the upper ends of the upright members is adapted to suspend the frame from the rod. Pairs of pins extend forwardly from the front and rearwardly from the back of the base member along parallel spaced apart first and second axes in a horizontal plane. Arms are pivotally pinned to the upright members for rotation about axes parallel to the first and second axes from lowest positions approximately sixty degrees below horizontal to highest positions approximately sixty degrees above horizontal. Detents prevent rotation of the arms below the lowest position or above the highest position. Torsion springs connected between the upright members and the arms bias arms toward their lowest positions. Another pin extends from the other end of each arm along axes parallel to the first and second axes. The axes are located and spaced so that the arcs generated by the axes of the pins on the arms when the arms are rotated between their lowest and highest positions are above the horizontal plane and between vertical planes extending through the first and second axes.
