Abstract

166,330. Richardson, S. April 9, 1920. Lenses, grinding; bevelling.-A machine for bevelling the edges of lenses comprises a bevel-edged grinding-disc 1 on a shaft 7, and a swivel head 21 pulled towards the disc by a spring 25. The head 21 is mounted between collars on a spindle 17, which is reciprocated by means of a cam 18* engaging a stationary pin 18‹. A indicator 22 is provided so that the cam can be brought to the correct position when centring a lens. A lens 5, carried by a spindle 9, is held between pads 10; a screw 11, with spring adjustment, clamps the lens. The spindle 9, which is rotatably mounted in the head 21 and carries a templet 26, is driven from the spindle 17 by gears 19, 20. The spindle 17 is driven from the shaft 7 by means of belts, an epicyclic reduction gear 14, and a clutch 18. The spindles 9, 17 can be adjusted towards or from the disc by means of a plate 23 and screws 24. A guideplate 27, contacting with the templet 26 and adjusted by a micrometer screw 29, may have a protuberance 28 so as to prevent the lens from grinding on the line of junction of the beveledges of the disc. A number of discs may be mounted on the same shaft so as to operate simultaneously upon a number of lenses. In a modification, the disc has an axial reciprocation instead of the lens-carrying spindle.
