Abstract
Abstract An apparatus for washing permanent wave hair rollers and method for using same wherein prior to washing said rollers wave solution saturated papers are removed therefrom in the washer which is in the form of a rotating drum through which a blast of air is forced. Baffles cause the curlers to fall into the air stream so that the curlers'' papers are driven into an exhaust cannister.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
94 words
In the washing of permanent wave curlers having permanent wave papers entwined therewith the process for separating the permanent wave papers from the curlers comprising inserting the permanent wave curlers along with their papers into a tumbling zone, forcing an air stream through said zone, tumbling the curlers and papers into said air stream to disperse curlers and permanent wave papers in the air stream, driving the permanent wave papers out of the tumbling zone, collecting the permanent wave papers in an exhaust zone, and subsequently washing said curlers while in said tumbling zone.
Claim 2
Dependent Claim
94 words
In the washing of permanent wave curlers having permanent wave papers entwined therewith the process for separating the permanent wave papers from the curlers comprising inserting the permanent wave curlers along with their papers into a tumbling zone, forcing an air stream through said zone, tumbling the curlers and papers into said air stream to disperse curlers and permanent wave papers in the air stream, driving the permanent wave papers out of the tumbling zone, collecting the permanent wave papers in an exhaust zone, and subsequently washing said curlers while in said tumbling zone.
Claim 3
Dependent Claim
173 words
Apparatus for separating permanent wave papers from curlers entwined therewith comprising a supporting frame; a tubular rotatable drum carried thereby, having a hollow center portion, an air inlet end, and an air exhaust end; means for inserting permanent wave curlers along with their papers, in the hollow inside portion of the rotatable drum; means for admitting forced air into the air inlet end of said drum; means for exhausting air from the air exhaust end of the drum after an air stream has passed therethrough; means for rotating said drum while forcing said air stream through the drum; baffle means in the hollow inside portion of said drum, disposed to disperse curlers and permanent wave papers in said forced air stream during drum rotation; a porous catch vessel removably attached over the air exhaust end of the drum to catch permanent wave papers carried out of the exhaust end by said forced air stream; and means for admitting a wash solution into the hollow portion of the rotatable drum and drain means therefor.
Claim 4
Dependent Claim
173 words
Apparatus for separating permanent wave papers from curlers entwined therewith comprising a supporting frame; a tubular rotatable drum carried thereby, having a hollow center portion, an air inlet end, and an air exhaust end; means for inserting permanent wave curlers along with their papers, in the hollow inside portion of the rotatable drum; means for admitting forced air into the air inlet end of said drum; means for exhausting air from the air exhaust end of the drum after an air stream has passed therethrough; means for rotating said drum while forcing said air stream through the drum; baffle means in the hollow inside portion of said drum, disposed to disperse curlers and permanent wave papers in said forced air stream during drum rotation; a porous catch vessel removably attached over the air exhaust end of the drum to catch permanent wave papers carried out of the exhaust end by said forced air stream; and means for admitting a wash solution into the hollow portion of the rotatable drum and drain means therefor.
Claim 5
Dependent Claim
28 words
The apparatus of claim 2 wherein the catch vessel is a closed wire drum having an open end adapted to fit over the exhaust end of the drum.
Claim 6
Dependent Claim
66 words
The apparatus of claim 2 wherein the drum rests on rollers carried by the supporting frame, wherein the means for rotating the tubular drum is a motor with a double drive shaft, one drive shaft being coupled to the rotatable drum, the other shaft being coupled to an air blower which in turn is connected through a chute to the air inlet end of said drum.
