Abstract
Abstract The invention is a detangling dryer comprising a housing with a supporting handle and fan to move air through the housing and heat it, and power means provides rapid reciprocating movement. A support on the housing exit has a frame carrying a pair of spaced outer comb means straddling a separate comb means in the frame, the frame being latched to the exit and the separate comb reciprocating and having teeth longer than the straddling spaced comb means and designed to avoid squeezing, pinching, or shearing of the hair. The comb carrying frame means is latched to the dryer which has a transmission for the reciprocating comb which transmission is automatically engaged and the comb is selfaligning when the frame is attached. Slots are provided to direct dryer air through and along the length of the comb means on both sides. Switching means selects the rate of air flow, air temperature, and actuation of the separate comb means so that temperature controlled air is directed through the combs to provide a shaking and detangling action only to the hair while drying it.

Claim 1
Independent Claim
194 words
A hair detangling dryer comprising, a housing with supporting handle, fan means supported to move air through said housing and exit one end thereof, means in said housing to heat the air therethrough. a removable support frame with latch structure means for attachment to said housing exit, power means in the housing providing rapid reciprocating movement, a pair of spaced outer comb means carried by said support frame, separate comb means attached to said reciprocating means and reciprocable in said frame by transmission means connecting said separate comb means through the housing to said power means, said separate comb means disposed to be straddled by said spaced comb means and having teeth longer than said straddling spaced comb means, the teeth of said separate comb means being transversely spaced and longitudinally aligned to substantially avoid pinching, squeezing, or shearing of the hair, and switching means operable to select the rate of air flow, air temperature, and actuation of said separate comb means, whereby air flow may be directed through the combs to provide shaking and detangling movement only to the air in all hairengaging positions of the comb means while passing temperaturecontrolled air therethrough.

A hair detangling dryer comprising, a housing with supporting handle, fan means supported to move air through said housing and exit one end thereof, means in said housing to heat the air therethrough. a removable support frame with latch structure means for attachment to said housing exit, power means in the housing providing rapid reciprocating movement, a pair of spaced outer comb means carried by said support frame, separate comb means attached to said reciprocating means and reciprocable in said frame by transmission means connecting said separate comb means through the housing to said power means, said separate comb means disposed to be straddled by said spaced comb means and having teeth longer than said straddling spaced comb means, the teeth of said separate comb means being transversely spaced and longitudinally aligned to substantially avoid pinching, squeezing, or shearing of the hair, and switching means operable to select the rate of air flow, air temperature, and actuation of said separate comb means, whereby air flow may be directed through the combs to provide shaking and detangling movement only to the air in all hairengaging positions of the comb means while passing temperaturecontrolled air therethrough.
Claim 3
Dependent Claim
32 words
Apparatus as described in claim 2 wherein said fan and separate comb means have separate motors to respectively supply power thereto, and said spaced outer comb means are fixed to said frame.
Claim 4
Dependent Claim
48 words
Apparatus as described in claim 1 wherein said transmission means includes, bar means reciprocally driven by an eccentric from said separate comb motor, and an arm extending from said separate comb means into engagement with said bar to impart reciprocation to said separate comb means in the frame.
Claim 5
Dependent Claim
44 words
Apparatus as described in claim 3 wherein said baR has a slot therein, and said arm is formed with a substantially pointed end thereon to engage said slot in any reciprocal position of said slot and comb to slide said comb into self-aligning position.
Claim 6
Dependent Claim
29 words
Apparatus as described in claim 4 wherein said frame has a plurality of openings. said openings being aligned to direct air along substantially the length of said comb means.
Claim 7
Dependent Claim
28 words
Apparatus as described in claim 5 wherein said openings are disposed on both sides of said frame to direct air along substantially the length of both spaced combs.
Claim 8
Dependent Claim
23 words
Apparatus as described in claim 5 wherein additional openings are also provided between said outer and separate comb means to direct air therethrough.
Claim 9
Dependent Claim
35 words
Apparatus as described in claim 7 wherein said additional openings and said frame openings are both provided along said comb means to direct air through and over all combs substantially along the entire length thereof.
