Abstract
574,084. Polishing lenses. AVIMO, Ltd., and STEVENS, H. C. M. June 30, 1944, No. 12482. [Class 60] A lens polishing machine comprises a rotary crank carrying a rotary tool and a pivoted arm carrying another tool so as to permit universal oscillatory movement. One tool h is mounted to rotate freely on a crank arm e, while the other tool k is mounted by a ball joint o on a stem n carried by a pivoted arm j. The crank may be rotated by friction gearing b.
