Abstract
Abstract A lightweight portable hair dryer is provided with a hair detangling comb consisting of two counter-reciprocating comb members positioned immediately adjacent the air discharge in the hair dryer. The hair dryer and the detangling comb are driven by two separate and independent motors which assure continued high volume air flow in spite of excessive loads being applied to the counter reciprocating combs. The supporting and driving means for the comb are positioned at either end of the elongated hot air discharge slot of the hair dryer.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
139 words
A hair drying and detangling appliance comprising a housing enclosing a first motor and an elongated tangential fan drivingly interconnected and positioned along one wall of said housing with said first motor and fan having their axes aligned, air intake means in said housing adjacent to said fan, air discharge means in said housing comprising an elongated slot substantially coextensive with said fan and interconnected with said fan by a duct within which a heater for heating the air is positioned, support means on opposite sides of said duct for mounting a pair of spaced parallel comb members, a second motor drivingly interconnected to said combs to reciprocate said combs in opposite directions, said combs being positioned to extend lengthwise in front of said slot outside of said housing with support portions extending into said housing adjacent said duct.
Claim 2
Dependent Claim
139 words
A hair drying and detangling appliance comprising a housing enclosing a first motor and an elongated tangential fan drivingly interconnected and positioned along one wall of said housing with said first motor and fan having their axes aligned, air intake means in said housing adjacent to said fan, air discharge means in said housing comprising an elongated slot substantially coextensive with said fan and interconnected with said fan by a duct within which a heater for heating the air is positioned, support means on opposite sides of said duct for mounting a pair of spaced parallel comb members, a second motor drivingly interconnected to said combs to reciprocate said combs in opposite directions, said combs being positioned to extend lengthwise in front of said slot outside of said housing with support portions extending into said housing adjacent said duct.
Claim 3
Dependent Claim
79 words
The combination of claim 1 wherein each comb includes a back portion extending parallel to said slot and teeth extending outwardly from said back portion in the direction of air flow from said slot, comb supports at both ends of said back portion extending in an opposite direction from said teeth, said supports having bifurcated ends which detachably engage with said support means, said comb supports extend into said housing between the ends of said slot and said duct.
Claim 4
Dependent Claim
36 words
The combination of claim 2 wherein each end of each said comb is supported on a lever pivoted to said housing, transmiSsion means interconnecting said second motor and one of said levers to oscillate said levers.
Claim 5
Dependent Claim
88 words
The combination of claim 3 wherein said second motor drives a crank pin which is eccentric to the axis of said motor, said transmission means including a drive block mounted for pivotal movement about an axis perpendicular to the axis of said second motor and driven in oscillating movement by said crank pin, connecting rods each pivotally connected to said drive block at one end and to one of said levers at the other end whereby the oscillating movement of said drive block is transmitted to said levers.
Claim 6
Dependent Claim
59 words
The combination of claim 1 wherein said housing comprises a body portion which encloses said first motor said fan and said heater and duct, said housing having a handle portion extending centrally from one end of said body portion parallel to the common axis of said first motor and fan, said second motor being enclosed in said handle portion.
Claim 7
Dependent Claim
70 words
The combination of claim 2 wherein said support means comprise a pair of links, each link supporting each end of both combs, having spaced plate portions which straddle a connecting block, each said blocks being pivotally connected to said plate portions at one end of said link, said bifurcated ends of said comb supports resiliently engaging said blocks to detachably retain said combs in driven engagement with said support means.
Claim 8
Dependent Claim
33 words
The combination of claim 6 wherein said bifurcated ends of said comb supports are formed with bearing portions which engage the opposed faces of said plate portions to resist twisting of said combs.
Claim 9
Dependent Claim
137 words
A combination hair drying and hair detangling appliance comprising a housing enclosing a motor driven fan and a heater, an air duct directing air from said fan across said heater to heat said air, an elongated slot formed in said housing at one end of said duct through which said heated air is discharged, a pair of spaced parallel combs extending lengthwise of said slot in the stream of air discharged from said slot, said combs having support portions extending into said housing at the ends of said slot, lever means within said housing but outside of said duct supporting each end of each comb, a second motor for reciprocating said combs, said lever means including a pair of connecting rods interconnecting said motor and said combs to reciprocate said combs in an out of phase relationship.
Claim 10
Dependent Claim
137 words
A combination hair drying and hair detangling appliance comprising a housing enclosing a motor driven fan and a heater, an air duct directing air from said fan across said heater to heat said air, an elongated slot formed in said housing at one end of said duct through which said heated air is discharged, a pair of spaced parallel combs extending lengthwise of said slot in the stream of air discharged from said slot, said combs having support portions extending into said housing at the ends of said slot, lever means within said housing but outside of said duct supporting each end of each comb, a second motor for reciprocating said combs, said lever means including a pair of connecting rods interconnecting said motor and said combs to reciprocate said combs in an out of phase relationship.
Claim 11
Dependent Claim
65 words
The combination of claim 8 wherein said housing includes a handle within which said second motor is enclosed, a power cord extending from said handle, said handle supporting a pair of switches one of which is connected to said power cord in series with said motor driven fan and heater and the other being connected to said power cord in series with said second motor.
Claim 12
Dependent Claim
37 words
The combination of claim 8 wherein said housing is formed by two cup housing halves, said lever means being supported for pivotal movement on bolts which extend through said housing halves and retain them in assembled relation.
