Abstract

661,899. Time check mechanism. SIEMENS BROS. & CO., Ltd. Feb. 3, 1950 [Feb. 4, 1949], No. 3187/49. Class 40 (iv). [Also in Group XX] The number display 2 of a time check mechanism of the electromagnetic step-by-step type is illuminated by a " light pipe " 1 (see Group XX) having at one end a polished, bevelled surface which serves to reflect light transmitted through the pipe and through which the number can be viewed. The bevelled surface may be cut away so that only the numerals are illuminated, and a lens may be provided.
