Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
84 words
A method for drying small articles of wearing apparel comprising the steps of: a) placing articles of wearing apparel on the rigid curved surface of a stationary drying chamber, said rigid curved surface maintaining its shape when subjected to circulating drying air; and b) tumbling and drying articles of wearing apparel placed on the rigid curved surface by forcing air under pressure along the rigid curved surface, the articles of apparel being tumbled by application of air under pressure, to expedite the drying thereof.
Claim 2
Independent Claim
84 words
A method for drying small articles of wearing apparel comprising the steps of: a) placing articles of wearing apparel on the rigid curved surface of a stationary drying chamber, said rigid curved surface maintaining its shape when subjected to circulating drying air; and b) tumbling and drying articles of wearing apparel placed on the rigid curved surface by forcing air under pressure along the rigid curved surface, the articles of apparel being tumbled by application of air under pressure, to expedite the drying thereof.
Claim 3
Dependent Claim
16 words
The drying method of claim 1, wherein: a) the drying chamber is of substantially drum shape.
Claim 4
Dependent Claim
95 words
Apparatus for drying small articles of wearing apparel, comprising: a) a housing; b) a stationary drying chamber within said housing in which small articles of wearing apparel are placed for drying; c) a first means in said housing for admitting air under pressure; d) a second means for tumbling the articles of wearing apparel in the stationary drying chamber when contacted by pressurized air admitted by said first means to effect rapid drying thereof; and, e) said second means including a rigid, curved surface configured for maintaining its shape when contacted by the pressurized air.
Claim 5
Dependent Claim
95 words
Apparatus for drying small articles of wearing apparel, comprising: a) a housing; b) a stationary drying chamber within said housing in which small articles of wearing apparel are placed for drying; c) a first means in said housing for admitting air under pressure; d) a second means for tumbling the articles of wearing apparel in the stationary drying chamber when contacted by pressurized air admitted by said first means to effect rapid drying thereof; and, e) said second means including a rigid, curved surface configured for maintaining its shape when contacted by the pressurized air.
Claim 6
Dependent Claim
47 words
The apparatus of claim 3, wherein: a) said drawing chamber is of drum shape and includes spaced side walls and a curved peripheral wall, said curved peripheral wall being configured for tumbling articles of wearing apparel placed on said curved peripheral wall when contacted by pressurized air.
Claim 7
Dependent Claim
63 words
The apparatus of claim 4, wherein: a) said first means comprises an inlet in said drum shaped drying chamber; and b) said second means includes the alignment of said inlet opening with the curved wall of said drying chamber, whereby air under pressure is directed along the curved wall to effect lifting and tumbling of articles of wearing apparel for drying the latter.
Claim 8
Dependent Claim
26 words
The apparatus of claim 5, with the addition of: a) access means in said housing for placing the articles of wearing apparel in said drying chamber.
Claim 9
Dependent Claim
19 words
The apparatus of claim 6 wherein: a) said access means is a door engaged with said curved peripheral wall.
Claim 10
Dependent Claim
23 words
The apparatus of claim 7, wherein: a) said door is curved, and b) said door being provided with a plurality of air vents.
Claim 11
Dependent Claim
18 words
The apparatus of claim 8, wherein: a) said side walls are provided with a plurality of air vents.
Claim 12
Dependent Claim
158 words
Apparatus for drying small articles of wearing apparel, for use with a conventional hand held hair dryer having a nozzle for exhausting pressurized air, said apparatus comprising: a) a housing including spaced opposed side walls and a connector wall between said side walls, at least a portion of which is rigid and curved, said at least a portion maintaining its shape when subjected to pressurized air from a hair dryer, thereby forming a stationary drying chamber into which the articles of wearing apparel are placed; b) said connector wall having an inlet opening adapted to receive the nozzle of a hair dryer; c) said inlet opening being aligned with the curved portion of said connector wall to effect movement of pressurized air from a hair dryer along the rigid curved portion of said wall into drying contact with the articles of wearing apparel, which are tumbled by continued application of air under pressure to expedite the drying thereof.
Claim 13
Dependent Claim
158 words
Apparatus for drying small articles of wearing apparel, for use with a conventional hand held hair dryer having a nozzle for exhausting pressurized air, said apparatus comprising: a) a housing including spaced opposed side walls and a connector wall between said side walls, at least a portion of which is rigid and curved, said at least a portion maintaining its shape when subjected to pressurized air from a hair dryer, thereby forming a stationary drying chamber into which the articles of wearing apparel are placed; b) said connector wall having an inlet opening adapted to receive the nozzle of a hair dryer; c) said inlet opening being aligned with the curved portion of said connector wall to effect movement of pressurized air from a hair dryer along the rigid curved portion of said wall into drying contact with the articles of wearing apparel, which are tumbled by continued application of air under pressure to expedite the drying thereof.
Claim 14
Dependent Claim
