Abstract

186,228. Greenwood, T. Aug. 22, 1921. Bevelling; lenses, grinding and polishing.- Comprises a machine. for bevelling the edges of a number of lenses simultaneously on a single grinding-wheel. The lenses A are mounted, by means of rubber washers b and pads held down by screw-operated levers b<1>, on spindles B rotatably supported in a carriage C which is slidable on the machine frame C<1>. The sliding movement of the carriage is controlled by a rotating templet D' having a shape corresponding with that of the lenses and carried by a spindle D mounted on the carriage C, the edge of the templet being maintained by a weight W in contact with an abutment G which may be fixed to, or adjustably mounted on, the frame C<1>. The spindles B are all driven at the same speed by spur gears mounted on the spindles, one of which is driven, through spur gearing, by, and at the same speed as, the templet spindle; the templet spindle is driven by means of a worm-wheel thereon which engages a worm mounted on a driven shaft e and slidable thereon with the carriage. The grinding-wheel H operates with its flat undersurface, and the spindle h is rotatably carried by a sleeve L which is adjustable axially by means of a hand-wheel M and gearing m, m<1> to compensate for wear. When circular lenses are to be bevelled, the carriage C may be locked in position. Water or other liquid is supplied to the wheel through a pipe r by a pump R.
