Abstract: 604,789. Grinding lenses. UNITED KING- DOM OPTICAL CO., Ltd., and MOORE, J. A. Dec. 3, 1945, No. 32644. [Class 60] A tool for grinding or smoothing solid bifocals comprises a part with spherical surface for the outer or distance portion of the lens and a separate part with conoidal surface for the inner or reading portion fixed in the first part in such a manner as to be axially adjustable therein. The body part of the tool comprises a plate 1 rigidly fixed in a short tube or ring 2 into the end of which is frictionally held, by brackets 4, a ring 3 for grinding the outer part of the lens. The grinding member for the inner part of the lens is a block 5, of approximately triangular section, adjustable axially by a screw 10 and clamped in a recess in the plate 1 by a screw 7. A second block 5a is similarly mounted opposite the block 5 for mechanical balance and alternate use. A lens blank 19, Fig. 3, is rotated about the axis OL, O being the centre of curvature of the outer part AB, DE and also of the spherical surface of the ring 3, while the tool is rotated about the axis OT. The surface of the block 5 is formed by rotation of the arc BC, having its centre at R, about the axis OT, and is thus slightly non-spherical and makes only line contact with the inner surface BD of the lens 19. During grinding the block 5a is adjusted to stand away from the lens blank and not as shown in Fig. 3. For a grinding operation the plate 1 is rigidly fixed to a spindle 15 by a taper fitting 16, Fig. 3, while for smoothing a looser connection 17, 18 Figs. 1, 2, is used. The tool may be made of brass when used with free abrasive. Specification 449,398 is referred to.
