Abstract
Abstract An apparatus for cutting hair that is comprised of a triangular housing, enclosing open scissor blades, from whose opposing flat sides are projected hollow tubes, one having several fitted extensions, the other having affixed to it a flexible plastic hose, tapered at the end, so that it is insertable into a vacuum suction device, thus supplying suction so that, with the extensioned tube placed on the subject's scalp, hair will be drawn up, through the housing and between open scissor blades, where it is cuttable at lengths dependent on the extensions used. A method of scissor positioned, vacuum haircutting employing this device.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
161 words
A vacuum haircutting apparatus comprising: (A) a scissor housing made up of two triangular pieces of flat plastic, set parallel to one another and joined at the sides, so that said housing holds scissor blades in a fixed position, once said blades have been inserted and opened by the operator; (B) a small opening at an acute angle of said housing allowing for the insertion of said pair of scissors; (C) two opposing openings in the middle of the flat sides of said triangular housing leading to opposing hollow tubes, projecting from said sides; (D) a flexible plastic hose attached to one of said projecting hollow tubes; whereby the application of a source of vacuum to one end of said flexible hose while the other projecting hollow tube is applied to the subject's scalp, will result in the subject's hair being pulled through said tube, and through said triangular housing and between said open scissor blades, where it is then cuttable.
Claim 2
Dependent Claim
161 words
A vacuum haircutting apparatus comprising: (A) a scissor housing made up of two triangular pieces of flat plastic, set parallel to one another and joined at the sides, so that said housing holds scissor blades in a fixed position, once said blades have been inserted and opened by the operator; (B) a small opening at an acute angle of said housing allowing for the insertion of said pair of scissors; (C) two opposing openings in the middle of the flat sides of said triangular housing leading to opposing hollow tubes, projecting from said sides; (D) a flexible plastic hose attached to one of said projecting hollow tubes; whereby the application of a source of vacuum to one end of said flexible hose while the other projecting hollow tube is applied to the subject's scalp, will result in the subject's hair being pulled through said tube, and through said triangular housing and between said open scissor blades, where it is then cuttable.
Claim 3
Dependent Claim
49 words
An apparatus according to claim 1 wherein the hollow tube nearest the subject's scalp has several fitted extensions of various lengths which allow the operator of said apparatus to choose, by affixing one or more of these extensions, a desired distance between the subject's scalp and the positioned scissors.
Claim 4
Dependent Claim
34 words
An apparatus according to claim 2 wherein the hollow tube furthest from the subject's scalp is attached to a flexible plastic hose long enough to reach from a seated person's head to the floor.
Claim 5
Dependent Claim
52 words
An apparatus according to claim 3 wherein the flexible plastic hose is attached to a tapered tube, whose circumference where it meets the hose is larger than any vacuum device opening, and whose circumference at the other end is smaller, insuring that the tube is insertable into any such vacuum device made.
