Abstract
305,015. Soc. Anon. des Etablissments Ducellier. Jan. 28, 1928, [Convention date]. Brush-holders. - A carbon brush 4 and a pressure spring 9 are secured in a holder 2 by a cap 7 having bentover parts 8, one of the parts 8<a> co-operating with a groove 15 in the holder to guide the cap into position. Loss of a securing screw 14 on removal of the cap is prevented by threading it at the end only and providing a diametrically reduced central portion which passes through a tapped hole in the cap. Connection between the brush 4 and the cap 7 is effected bv a conductor 6. According to the Specification as open to inspection under Sect. 91 (3) (a) the carbon brush may be replaced by a greased wick for lubricating the commutator. This subject-matter does not appear in the Specification as accepted.
