Abstract: A hair dressing comb assembly comprising a generally cylindrical housing from one end of which a handle extends, and a plurality of similar longitudinally extending slots are arranged in circumferentially spaced relation around the housing respectively to receive elongated toothed comb members having relatively thin ends projecting beyond the toothed portions, the housing containing in opposite ends similar cam members interconnected longitudinally and movable axially by a manually operable sleeve on the exterior of the handle for movement in one direction to cause the cams to engage the thin ends of the comb members to project the combs outwardly to full operative positions, and separate retracting springs engageable with the thin ends of the comb members to fully retract them simultaneously into the slots in the housing when the sleeve on the handle moves the cam members in the opposite direction.
