Abstract

629,788. Collectors. PATTERSON, C. A., and SMITH, F. C. Nov. 28, 1947, No. 31537. [Class 38 (i)] A brush 1, especially for use with electric measuring equipment, is normally held out of engagement with a slip-ring 6 by means of a spring 5, but is urged into engagement therewith by compressed air acting on the left-hand end of an insulating plunger 3, when the measuring equipment is to be used. The brush is cooled by any air that escapes past the plunger 3.
