Abstract
226,002. King, P. T. Nov. 6, 1923. Brush-holders.-In an electric motor, the pressure applied by a spring to a brush is arranged to be proportional to the size of the brush, so that in the case of rotating brush-gear, the lifting of the brushes caused by centrifugal force at excess speed of rotation always takes place at substantially the same speed. The brush 1, Fig. 1, slides in a metal bush 2, fitted' into but insulated from the end plate 3. An insulated lever 6 mounted on a spindle has one arm bearing against a brush. and through the other arm there passes a spindle 13 fixed to a curved arm 11 also mounted on the spindle 5. A laminar spring 10 bears on the curved arm and at the other end is anchored in a washer 16. The pressure of the spring may be adjusted' by means of a lever 18 engaged within a slot in the washer. The curved arm 11 is so designed that the pressure exerted on the brush is directly proportional to the length of the brush. In a modification, Fig. 3, the lever 6 and arm 11 are secured by means of split lugs 23 and screws 24 to an insulating sleeve 21 journaled on a spindle 22.
