Abstract
Abstract An apparatus for treating hair to produce a flat curl comprises a cup-shaped member for receiving a manually preformed spiral curl of hair, a pressure member arranged for insertion into the cup-shaped member to subject the preformed curl to pressure, and operator means for moving one of said members relative to the other to apply and release said pressure. Means are provided for applying a rehydrating vapor into the cup-shaped member in direct contact with the preformed curl of hair to keep the curl in its normal hygrometric state while it is being subjected to said pressure.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
260 words
An apparatus for treating hair to curl it and to maintain it in the form of curls, said apparatus comprising a cup-shaped member for receiving a lock of hAir, a pressure member arranged for insertion into said cup-shaped member to subject the lock of hair to pressure, means for moving one of said members relative to the other to apply and release said pressure, and means for applying a rehydrating vapor into direct contact with said lock of hair to keep said lock in its normal hygrometic state while it is being subjected to said pressure, said apparatus including a first arm carrying said cup-shaped member at its free end, a second arm pivotally connected to said first arm and carrying said pressure member at a position wherein it may enter said cupshaped member when said arms are pivoted relative to one another, said pressure member taking the form of a container into which a liquid can be introduced, said means for applying rehydrating vapor including a heater for transforming liquid in said container into a vapor, the lower surface of said container being positioned in facing relation to said cup-shaped member and being formed with at least one hole for egress of said vapor into direct contact with a lock of hair in said cup-shaped member, and a slider mounted for movement along said second arm, said slider having at least one pin projecting therefrom for holding a curl of hair in position within said cup-shaped member when said slider is at a predetermined location along said second arm.
Claim 2
Independent Claim
260 words
An apparatus for treating hair to curl it and to maintain it in the form of curls, said apparatus comprising a cup-shaped member for receiving a lock of hAir, a pressure member arranged for insertion into said cup-shaped member to subject the lock of hair to pressure, means for moving one of said members relative to the other to apply and release said pressure, and means for applying a rehydrating vapor into direct contact with said lock of hair to keep said lock in its normal hygrometic state while it is being subjected to said pressure, said apparatus including a first arm carrying said cup-shaped member at its free end, a second arm pivotally connected to said first arm and carrying said pressure member at a position wherein it may enter said cupshaped member when said arms are pivoted relative to one another, said pressure member taking the form of a container into which a liquid can be introduced, said means for applying rehydrating vapor including a heater for transforming liquid in said container into a vapor, the lower surface of said container being positioned in facing relation to said cup-shaped member and being formed with at least one hole for egress of said vapor into direct contact with a lock of hair in said cup-shaped member, and a slider mounted for movement along said second arm, said slider having at least one pin projecting therefrom for holding a curl of hair in position within said cup-shaped member when said slider is at a predetermined location along said second arm.
Claim 3
Dependent Claim
40 words
The apparatus of claim 1 wherein said apparatus is generally pistol-shaped, said first arm being attached to a hand grip and said second arm being attached to a trigger for effecting relative pivotal movement of said first and second arms.
Claim 4
Dependent Claim
13 words
The apparatus of claim 1 wherein said heater is an electrical resistance heater.
Claim 5
Dependent Claim
24 words
The apparatus of claim 1 including resilient means for urging said slider toward a location along said second arm remote from said pressure member.
Claim 6
Dependent Claim
26 words
The apparatus of claim 4 including means for latching said slider at said predetermined position along said second arm against the restraint of said resilient means.
Claim 7
Dependent Claim
60 words
The apparatus of claim 5 including means on aid first arm for disengaging said latching means when said first and second arms are so pivoted that said pressure member enters said cup-shaped member, thereby to permit said resilient means to return said slider from its latched position to said remote location to withdraw said projecting pin from said cup-shaped member.
Claim 8
Independent Claim
161 words
An apparatus for treating hair in order to produce a flat curl, said apparatus comprising a cup-shaped member for receiving manually preformed spiral curls of hair, said cup-shaped member being open to permit the spirals to initially be held in place by an operator''s finger, a first arm carrying said cup-shaped member at its free end, a second arm pivotally connected to said first arm and carrying a pressure member arranged for insertion into said cup-shaped member to subject the said spirals to pressure, holding means carried by said second arm and comprising a projecting pin operative to hold said spiral curl of hair in position within said cup-shaped member when the operator''s finger is removed, means for moving one of said members relative to the other to apply and release said pressure, and means for applying a rehydrating vapor into direct contact with said curl to keep the hair in its normal hygrometric state while being subjected to said pressure.
Claim 9
Independent Claim
161 words
An apparatus for treating hair in order to produce a flat curl, said apparatus comprising a cup-shaped member for receiving manually preformed spiral curls of hair, said cup-shaped member being open to permit the spirals to initially be held in place by an operator''s finger, a first arm carrying said cup-shaped member at its free end, a second arm pivotally connected to said first arm and carrying a pressure member arranged for insertion into said cup-shaped member to subject the said spirals to pressure, holding means carried by said second arm and comprising a projecting pin operative to hold said spiral curl of hair in position within said cup-shaped member when the operator''s finger is removed, means for moving one of said members relative to the other to apply and release said pressure, and means for applying a rehydrating vapor into direct contact with said curl to keep the hair in its normal hygrometric state while being subjected to said pressure.
Claim 10
Dependent Claim
81 words
The apparatus of claim 7 in which said pressure member takes the form of a container into which a liquid can be introduced, said means for applying rehydrating vapor including a heater for transforming liquid in said container into a vapor, the lower surface of said container being positioned in facing relation to said cup-shaped member and being formed with at least one hole for egress of said vapor into direct contact with a curl of hair in said cup-shaped member.
Claim 11
Dependent Claim
62 words
The apparatus of claim 7 wherein said holding means is mounted for movement relative to said cup-shaped member, and means for moving said holding means to withdraw said projecting pin froM said cup-shaped member when said relative movement of said members causes said pressure member to reach a position such that said pressure member presses on the spirals in said cup-shaped member.
