Methods and apparatus for trimming hair and disposing of hair clippings

Claim 2

Apparatus for trimming hair and recovering cut hair strands for disposal comprising a shell, a stationary blade and a reciprocating blade secured in a selected end of said shell, means in said shell for moving said reciprocating blade to trim the hair, an air inlet adjacent said stationary blade and said reciprocating blade, means for creating a vacuum in said air inlet adjacent to said blades, means for storing cut hair strands which are drawn into said air inlet by said vacuum, means for removing cut hair strands from said storing means, and means in said shell for creating air pressure at said blades, said air pressure creating means moving air over said blades in a direction which is out of and away from said shell, the moving air being in communication with the vacuum created by said vacuum creating means, whereby undesired accumulation of cut hair strands in said shell is inhibited, and cut hair strands are removed and stored for disposal.

Claim 3

The apparatus of claim 1 comprising means for cooling said means for moving said reciprocating blade.

Claim 4

The apparatus of claim 2 wherein said pressure creating means, said vacuum creating means and said cooling means comprises a single fan.

Claim 5

The apparatus of claim 3 wherein said fan comprises a rotating suction fan having two spaced, flat surfaces separated by a plurality of curved ribs, and a center opening in one of said flat surfaces for drawing air between said flat surfaces.

Claim 6

The apparatus of claim 4 wherein said fan comprises a top piece, a bottom piece, and means for securing said top piece to said bottom piece, said top piece and said bottom piece each having at least one of said ribs.

Claim 7

The apparatus of claim 4 wherein said reciprocating blade moving means comprises a motor, said motor also turning said fan.

Claim 8

The apparatus of claim 1 comprising filter means for isolating the hair strands from said vacuum creating means.

Claim 9

The apparatus of claim 7 wherein said filter means comprises a screen.

Claim 12

Apparatus for trimming hair and recovering cut hair strands for disposal comprising a shell, means for storing a battery in said shell, said battery storage means having a battery end cap in said shell for installing and removing the battery, a stationary blade and a reciprocating blade secured in a selected end of said shell, means in said shell for moving said reciprocating blade to trim the hair, an air inlet adjacent said stationary blade and said reciprocating blade, means for creating a vacuum in said air inlet, means for storing cut hair strands which are drawn into said air inlet by said vacuum, means for removing cut hair strands from said storing means, said removing means including a clean-out door for removing the cut hair strands from said storing means, and means for creating air pressure at said blades, said air pressure creating means moving air over said blades in a direction which is out of and away from said shell, the moving air being in communication with the vacuum created by said vacuum creating means, whereby undesired accumulation of cut hair strands in said shell is inhibited, and cut hair strands are removed and stored for disposal.

Claim 13

Apparatus for trimming hair and recovering cut hair strands for disposal comprising a shell, means for storing a battery in said shell, said battery storage means having a battery end cap in said shell for installing and removing the battery, a stationary blade and a reciprocating blade secured in a selected end of said shell, means in said shell for moving said reciprocating blade to trim the hair, an air inlet adjacent said stationary blade and said reciprocating blade, means for creating a vacuum in said air inlet, means for storing cut hair strands which are drawn into said air inlet by said vacuum, means for removing cut hair strands from said storing means, said removing means including a clean-out door for removing the cut hair strands from said storing means, and means for creating air pressure at said blades, said air pressure creating means moving air over said blades in a direction which is out of and away from said shell, the moving air being in communication with the vacuum created by said vacuum creating means, whereby undesired accumulation of cut hair strands in said shell is inhibited, and cut hair strands are removed and stored for disposal.

Claim 14

The apparatus of claim 10 wherein said shell comprises two mating shell halves and means for securing said shell halves together, said clean-out door and said battery cap interlocking with each other and further securing said shell halves together.

Claim 15

Apparatus for trimming hair and recovering cut hair strands for disposal comprising a shell, a stationary blade and a reciprocating blade secured in a selected end of said shell, means in said shell for moving said reciprocating blade to trim the hair, said means for moving said reciprocating blade including a motor, a battery for energizing said motor, and a switch for controlling energy to said motor, said battery being located adjacent to and substantially parallel with said motor, so that the most of the weight of the apparatus is in the user's palm during use, and means for creating air pressure at said blades, whereby undesired accumulation of cut hair strands in said shell is inhibited.

Claim 16

Apparatus for trimming hair and recovering cut hair strands for disposal comprising a shell, a stationary blade and a reciprocating blade secured in a selected end of said shell, means in said shell for moving said reciprocating blade to trim the hair, said means for moving said reciprocating blade including a motor, a battery for energizing said motor, and a switch for controlling energy to said motor, said battery being located adjacent to and substantially parallel with said motor, so that the most of the weight of the apparatus is in the user's palm during use, and means for creating air pressure at said blades, whereby undesired accumulation of cut hair strands in said shell is inhibited.

Claim 17

The apparatus of claim 12 wherein said shell includes an inclined side wall which extends from a vertical side wall at an angle of about 45 degrees to said vertical side wall, said switch being located on said inclined wall in about the center of said shell.
