Abstract

7392. Taylor, H. D. March 24. Reflectors. - Mirrors of double reflecting optical squares and other flat mirrors are mounted by means of circular pallets p with spherical holes, into which are fitted, by grinding, ball - headed screws a, screwed through bosses on the frame and secured bv lock-nuts. On the opposite side to these screws are sliding rods r, pressed by springs s and also provided with ball-ends and pallets. The mirror is held at a third place by an antagonist screw and spring arrangement. The frame is preferably made of cast iron or of a mixture, as set out in Specification 20,315/08, of 57 to 60 per cent of cast iron and 43 to 40 per cent of nickel, or of 69 to 72 of cast iron and 31 to 28 per cent of nickel, so as to be of the same thermal expansion as glass.
