Abstract

599,581. Indicating apparatus. POOLE, R. Sept. 19, 1945, No. 24222. [Class 106(iv)] The dial c of an indicating instrument is gripped between the main part A of a casing and a front cover moulded from a transparent plastic material and comprising a face part D and flange D 1. A glass E <1> is mounted in a frame E, preferablv moulded from black plastic material, the frame E and cover part D<1> being clamped to the casing A by bolts F. The parts D, D <1> may be formed in one piece or in two pieces and permanently united by cement or solvent. In either case the outer circumferential surface of the part D<1> may be roughened or otherwise formed to increase the lateral transmission of light to the dial c. Specification 586,535, [Group XXIX], is referred to in the Provisional Specification.
