Abstract
Abstract A device for drying and/or setting hair which enables the wearer to move about freely during use thereof. The device comprises separate hood and cap members. The cap is constructed of a multilayer, open mesh, moisture-absorbing material which is initially placed over the wearer''s hair. The hood is formed of alternating layers of asbestos or glass fiber cloth with additional layers of heat-retaining fibrous packing and flexible heat-reflecting foil placed therebetween. The hood, after being heated by external heating means to a temperature of about 200* C., is placed over the cap thereby providing the requisite thermal energy for drying the hair.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
103 words
A hair-drying device adapted to allow the user to move freely about during use thereof, comprising a separate heat-resistant cap member shaped to cover the hair portion of the user''s head including means for absorbing moisture from the wet hair, and a heat-storing and distributing hood member positioned over said cap member, said hood member comprising a plurality of layers including a relatively thick heat-retaining layer of fibrous nonmetallic heat-resistant material and at least one layer of thin flexible reflective metal foil disposed inwardly of said heat-retaining layer for regulating the flow of thermal energy from said heat-retaining layer inwardly to the hair.
Claim 2
Dependent Claim
103 words
A hair-drying device adapted to allow the user to move freely about during use thereof, comprising a separate heat-resistant cap member shaped to cover the hair portion of the user''s head including means for absorbing moisture from the wet hair, and a heat-storing and distributing hood member positioned over said cap member, said hood member comprising a plurality of layers including a relatively thick heat-retaining layer of fibrous nonmetallic heat-resistant material and at least one layer of thin flexible reflective metal foil disposed inwardly of said heat-retaining layer for regulating the flow of thermal energy from said heat-retaining layer inwardly to the hair.
Claim 3
Dependent Claim
25 words
The device in accordance with claim 1, wherein said member includes at least one open mesh layer formed of heat-resistant fibers capable of absorbing moisture.
Claim 4
Dependent Claim
36 words
The device in accordance with claim 2, wherein said member is formed of a plurality of layers, each being woven from natural fiber material, one of said layers having mesh openings substantially smaller than another layer.
Claim 5
Dependent Claim
61 words
The hair-drying device of claim 1, and wherein said hood member is provided with a plurality of layers of thin flexible reflective metal foil disposed inwardly of said heat-retaining layer for regulating the inward flow of thermal energy, with thin layers of woven heat-resistant material interposed between the metal foil and the heat-retaining layer and between the metal foil layers, respectively.
Claim 6
Dependent Claim
32 words
The hair-drying device of claim 4, and wherein said metal foil comprises aluminum and said woven heat-resistant material comprises insulating material taken from the group consisting of fibrous glass and fibrous asbestos.
Claim 7
Dependent Claim
41 words
The hair-drying device of claim 5, and wherein said cap member comprises a plurality of layers of woven natural fiber material, one of said natural fiber layers having mesh openings substantially smaller than the mesh openings of the layer adjacent thereto.
Claim 8
Dependent Claim
21 words
The hair-drying device of claim 6, and relatively thin inner and outer layers of insulating fibrous material on the hood member.
