Abstract
This relates to the mounting of brushes in a rotary electrical joint in a manner wherein the frictional force applied to a brush by a rotary member is restrained so as to eliminate prior tilting of the brush in a manner wherein excessive wear occurred adjacent the leading edge of the brush. Most particularly, the brush is so restrained wherein any tendency thereof to pivot will occur generally about an axis disposed adjacent the leading edge so that there is a uniform force application of the brush against the rotary member and thus a uniform wearing of the brush.
