Locally Cooled and Ventilated Brush Assembly

The apparatus as depicted in Fig. 1 and Fig. 2 provides a grounding means for a rotating head device.

As shown in Fig. 1, the grounding means 10 is a brush assembly impressed against conductive rotating ring 12. The brush assembly with a spring support and conductive handle support 18 is electrically connected to frame ground. Conductive rotating ring 12 is, in turn, connected to the part of a rotating circuit that needs to be grounded.

Fig. 2 is a cross-sectional view of the brush holder assembly 10. Brush holder assembly 10 is comprised of brush 14 which is connected to spring support 16. Spring support 16 is then connected to conductive handle support 18. Handle support 18 with its attachment is fitted within brush holder frame 20. Brush holder frame 20 is comprised of an inner wall 22 and an outer wall 24 with air passage 26 between the walls.

In operation, debris which is generated by brush 14 is removed by air in the direction shown by arrows 28.
