Abstract
A hair cutting device includes a housing defining a passage having an inlet and outlet with a cutter and an impeller between said inlet and outlet. A hair directing apparatus is positioned between the cutter means and the impeller to direct the hair to the periphery of the cutter and the inlet is adjustable with respect to the inlet. The cutter includes two blades one of which is rotated with an output motor shaft and the other is reciprocated on the output shaft. The drive motor is reversible and a heating element can be attached to the outlet to convert the device to a blower-dryer.
Claims17
A suction type hair cutting device comprising a housing defining a passage having an inlet and an outlet, blade means between said inlet and said outlet with drive means imparting a cutting action to said blade means and an impellor driven by said drive means producing a suction at said inlet, and a conical element rotatable with said blade means for directing hair to the periphery of said passage for said cutting action.
A hair cutting device comprising a housing having a passage with an inlet end, a motor in said passage having a driven output shaft, first and second cooperating cutting blades having peripheral cutting edges rotatable with said shaft, said first blade being secured to said shaft and said second blade being mounted for relative rotation on said shaft and means between said shaft and second blades for producing reciprocating motion between said blades during rotation thereof.
A hair cutting device comprising a housing having a substantially circular passage with an inlet end, a motor in said passage having a driven output shaft, first and second substantially circular cooperating cutting blades having peripheral cutting edges rotatable with said shaft, means between said shaft and one of said cutting blades for producing reciprocating motion between said blades during rotation thereof, and a cone connected to and rotatable with said shaft for directing hair to the periphery of said blades.
A hair cutting device comprising a housing having a passage with an inlet end and an outlet end, a motor in said passage having a driven output shaft, first and second cooperating cutting blades having peripheral cutting edges rotatable with said shaft, means between said shaft and one of said cutting blades for producing reciprocating motion between said blades during rotation thereof, an impeller rotatable with said output shaft, collector means on said outlet end, and valve means adjacent said outlet end opened in response to air flow in said passage and closed with said air flow is interrupted.
