Abstract

2015. Barker, L. C., and Burleigh, J. W. Feb. 1. Brush-holders.- Relates to brush. holders for dynamo - electric machines in which the brush-carrying member slides on a frame carried by the rocker, t h e brush - carrier and frame being connected by an adjustable helical spring. The radial carbon brush A Fig. 1, is gripped by the jaws B<1> of the bolder B, preferably made of aluminium, which is provided with sleeves B<3>, B<4> adapted to slide on pins C<1>, C<2> on the frame C, or with other guides. In the hollow pin C<1> is arranged the helical spring D, secured at one end to the frame C and at the other to a screwed spindle D', which engages a nut D', by which the tension of the spring, and thereby the pressure of the brush on the commutator, is adjusted. In a modification, Fig. 3, pins H pivoted to the holder B engage slots C<3> in the frame. The screw J, by which the frame C is secured to the rocker F, may also act as a guide for the holder. A screwed spindle G serves to press the brush against the jaws B'.
