Abstract

1,177,270. Pens. J. R. TUGWOOD. 23 Oct., 1967, No. 48143/67. Heading B6P. [Also in Division G2] Apparatus for marking a lens blank B which has a reading segment therein comprises a base 20 containing a light projection system by which superposed images of segment positioning indicia and of the blank B mounted on pegs 34 are projected on to a viewing screen 160 in a slide 92 mounted in a head 66 hinged to a base 20, the blank being manually adjusted to locate its segment within the positioning images, before an inked strip 118 or the slide is moved over the blank to mark it. Pegs 34 extend from a transparent plate 24 with two fixed perpendicular scales against which are viewed images (a) of the adjustably spaced edges of two transparent jaws such as 230 to define the width of the segment, and (b) of a cord 270 adjustably mounted on a U-shaped bracket 262 to define the chord of the segment, and (c) of a line engraved on a transparent plate 250 movable to locate slide 146 bearing said jaws. Slide 92 is movable along bars 140 from the position shown, where depression of plunger 86 inks the strip 118 in cup 82, to a position overlying blank B where further depression of the plunger marks the blank. Strip 118 is angularly adjustable by rotating a dial 122 which may be locked in a selected position.
