Abstract

523,393. Actuating controllers. BROOKHIRST SWITCHGEAR, Ltd., and LANCELEY, C. Dec. 1, 1938, No. 8738/40. Divided out of 522,048. Drawings to Specification. [Class 38 (iii)] The Specification comprises subject-matter described in Specification 522,048, but the claims of the present Specification relate especially to the lateral displacement of the axis of operation of the handle from the axis of the drum so as to facilitate group mounting of a number of controllers, and to the provision of a secondary moving part of the handle. Specification 363,046 also is referred to.
