  • This -invention relates -toan apparatusl for stant torque means illustratively shown comprises a driving element having a pin and a driven element having a receiving slot for the pin which slot is out at such an incline as to result in relative axial movement of the driven elementin response to relative rotary movement between the driving and driven elements, spring biasing means being provided tooppose such relative r- 'tary movement.
  • the operation of the brush is effected in a total absence of any stalling action due to excessive irictional contact between the brush and polishing surface. This is accomplished by the automatic lifting of the excessive frictional load.
  • ' vlt is a maiorl object of this invention to provide a polishing device having a brush adapted to operate at a constant torque regardless of the friction.
  • Another object is to provide a rotary brush device having no tendency to creep or travel in sala direction contrary or different from that intended by the operator oi the polishing device.
  • a further object is to provide a brush device for the suction end of a vacuum cleaner.
  • Still another objectr is to provide a simple, durable, low cost and highly eftlcient machine which is light and more easily handled than the usual electrically powered polishing devices.
  • a further object is to provide a polishing device having a much lower center of gravity and henceaV greater stability thanv the conventional motor driven unit.
