Abstract

831,333. Brush holders for dynamo-electric machines. MINISTER OF SUPPLY. Aug. 16, 1957 [May 17, 1956], No. 15471/56. Class 35. A dynamo-electric machine embodies a commutator 19 and brushgear comprising a brush 14 carried intermediate the length of a thin flexible metal strip 13 secured at one end to the free end of a cantilever spring arm 12 supported on a block 15 and at the other end in one embodiment to the block, the spring arm applying a tensile load substantially axially of the strip 13 which, against such load, is deflected by the commutator from the straight condition. As shown there are two cantilever arms 12 which may be part of a spring 11 or parts of two separate springs slotted to receive screws 16 adjustably securing them to the block which is in turn adjustably secured to the machine casing, not shown, by screws 17. At the end of strip 13 is a take-off lead connecting tag 18.
