Abstract
A slideable control is provided for use in retractable bristle brushes. It operates by co-action with a rotatable, cylindrical mandrel carrying pivoted bristles and having an angular cam slot. The control includes a longitudinally slideable button in the handle which has a control pin operatively extending through a control slot in the handle and then into the cam slot to cause rotation of the mandrel. The angular cam slot includes an axial portion at each end to receive the control pin and to lock the mandrel in a position with the bristles either fully retracted or fully extended. The control button includes a pair of parallel guide blades, one on each side of the control pin, slideable within slotted guides in the handle, to reduce torque between the control pin and the cam slot. The control slot may include detents proximate to its ends to receive and hold the control pin against longitudinal movement.
