Abstract

470,001. Switch contacts. SPERRY GYROSCOPE CO., Ltd., and HARDING, W. G. Jan. 30, 1936, No. 2894. [Class 38 (v)] [Also in Group XXXVIII] A circular group of contact segments is formed by cutting slots 49 in a conducting cylinder, Figs. 5 and 6, wiring the sections together in the order required as shown in Fig. 7, using the ring as an insert whilst the unit is moulded and machining out the centre portion of the ring until the cylindrical surface intersects the slots as shown in Fig. 1. Specifications 8678/00, [Class 118], and 434,124 are referred to.
