Abstract: 1,175,731. Casting composite articles; grinding. TEXTRON Inc. 2 Jan., 1967 [26 Jan., 1966], No. 107/67. Headings B3D and B3F. [Also in Division B8] To facilitate holding a lens blank L for edgegrinding, a block is cast on the blank (supported on pins 56 of a casting apparatus) by means of a mould 84 in one end of an arm 74 by which it is swung horizontally and lowered into position on the blank L to clamp the latter in position. A quantity of molten alloy from a heated reservoir 141 is metered by a valve 162, Fig. 6, which, when inverted by a handle 180, dispenses the metal dose through a nozzle 155 into the mould 84 to be cooled by liquid flowing through the arm 74 and a groove 130 around the mould. Manipulation of a screw 169, Fig. 4, adjusts the capacity of the valve 162. The melt reservoir 141 is mounted adjacent a housing (320), Fig. 1 (not shown), containing mirrors and a viewing lens (137), on a circlesegment-shaped platform (turret) 130 swingable in a horizontal arc so that either the reservoir with nozzle 155, or the housing (320), together with its associated aperture in the platform, can be swung to a location above the working position of a hollow base 20 of the apparatus. A similar, lower platform (turret) 40, swingable about the same pillar (38), bears two identical transparent reticle plates 54 in adjacent platform apertures, Fig. 2 (not shown). A lens blank L is oriented by the operator, viewing through the housing (320), on the support pins 56 of a reticle plate 54 in the working position, in relation to preset transparent reference members 230, 244 and a crossing cord 270. Platform 130 is then swung to replace the viewing housing (320) by the metal feed 141, 155. After the metal has been fed, the lower platform 40 is swung to replace the loaded reticle 54 (with its cooling mould 84 and arm 74) by the other reticle, with its own mould 84 and arm 74 in inoperative position, Fig. 2 (not shown), ready to receive a further lens blank L. Light from a lamp is reflected up by a mirror in the hollow base 20 through the reticle plate 54 in the working position, and through a ground glass screen (139), Fig. 1 (not shown), in the upper platform 130 and the lens (137) to the upper mirrors and a window in the housing (320) for facilitating the presetting of the reference members 230, 244, 270 and manually orienting the lens blank. Reference has been directed by the Comptroller to Specification 995,819.
