Abstract

399,515. Adjusting wireless-apparatus. STANDARD TELEPHONES & CABLES, Ltd., HODGSON, A. D'A., and SMITH, W., Connaught House, Aldwych, London. April 6,1932, No. 9887. [Class 37.] A radio control, which may be remote, comprises an operating-shaft having adjustable stops rotatable coaxially therewith and locked in predetermined positions with respect to another rotatable member having two spring- loaded clicks each engaging one of the stops. As shown, indicators 6, 7 provided with apertures 12 are loosely mounted on a collar 5 and are clamped into pre-set positions by a cam 9 which presses them into engagement with a back-plate 11. A projection 13 on the dial 1 traverses an arcuate slot 4 in a plate 3 and carries ball clicks 14 so that the dial can be engaged and held in the positions set by the indicators. The dial is prevented from moving beyond the click positions by a further stop 15.
