Abstract

323,857. Electrolux,Ltd., (Inventia Patent-Verwertungs-Ges.). Nov. 12, 1928. Brush-holders.-In a brush-gear of the type comprising a carbon &c. brush 14 sliding in a tubular holder 16 under the action of a spring 15 pressing against a contact plate 22 to which the brush is connected by a conductor 21 and which is retained in place by a screwed insulating cap 20, means are provided to prevent the contact plate from rotating with the cap. For this purpose the plate 22 is formed with turned-up portions 23 engaging with flattened surfaces on the holder 16. The portions 23 are preferably longer than the threaded portion of the cap 20. To secure the conductor 21 to the plate 22 a tongue 24 is stamped out of the plate 1 and the end of the conductor 21 passed through the opening thus formed The tongue 24 is then bent down on to the conductor and the whole secured with solder.
