Abstract
Abstract A reversible crimper-straightener for hair including a handle, a pair of pivoted clamp halves secured to the handle, a pair of reversible plates, each plate including a crimping surface on one side thereof and a flattening surface on the opposite side thereof, a heater within at least one of the plates, and tracks and rails on the plates and the clamping halves for securing one of the plates within one of the clamp halves and the other of the plates within the other of the clamp halves. The plates are reversible so that, alternatively, the crimping surfaces or the straightening surfaces face and are proximate to one another.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
139 words
In a hair curling unit, said unit including a handle and pivoted upper and lower clamp halves thereon and electrical connections therein, that improvement including a pair of reversible heatable metal plates, each of said plates having a first surface on one side thereof and a second surface on the other side thereof, said first surfaces being complementary to one another and said second surfaces being complementary to one another, means for reversibly securing one of said plate to one of said clamp halves and the other of said plates to the other of said clamp halves, with either said first surfaces or said second surfaces facing each other, and heating means associated with at least one of said plates, whereby said hair curling unit may be configured for use with either of said first or said second surfaces.
Claim 2
Dependent Claim
139 words
In a hair curling unit, said unit including a handle and pivoted upper and lower clamp halves thereon and electrical connections therein, that improvement including a pair of reversible heatable metal plates, each of said plates having a first surface on one side thereof and a second surface on the other side thereof, said first surfaces being complementary to one another and said second surfaces being complementary to one another, means for reversibly securing one of said plate to one of said clamp halves and the other of said plates to the other of said clamp halves, with either said first surfaces or said second surfaces facing each other, and heating means associated with at least one of said plates, whereby said hair curling unit may be configured for use with either of said first or said second surfaces.
Claim 3
Dependent Claim
28 words
In a hair curling unit as set forth in claim 1 that improvement in which said first surfaces are configured for crimping and said second surfaces are flat.
Claim 4
Dependent Claim
168 words
In a hair curling unit, said unit including a handle and pivoted upper and lower clamp halves thereon and electrical connections therein, that improvement including a pair of heatable metal plates, each of said plates having a first surface on one side thereof and a second surface on the other side thereof, said first surfaces being complementary to one another and said second surfaces being complementary to one another, means for securing one of said plates to one of said clamp halves and the other of said plates to the other of said clamp halves, with either said first surfaces or said second surfaces facing each other, said securing means including complementary longitudinal tracks and rails on the said clamp halves and said plates, and heating means associated with at least one of said plates, whereby said plates may be slidingly inserted into, or removed from, said clamp halves so that said hair curling unit may be configured for use with either said first or said second surfaces.
Claim 5
Dependent Claim
168 words
In a hair curling unit, said unit including a handle and pivoted upper and lower clamp halves thereon and electrical connections therein, that improvement including a pair of heatable metal plates, each of said plates having a first surface on one side thereof and a second surface on the other side thereof, said first surfaces being complementary to one another and said second surfaces being complementary to one another, means for securing one of said plates to one of said clamp halves and the other of said plates to the other of said clamp halves, with either said first surfaces or said second surfaces facing each other, said securing means including complementary longitudinal tracks and rails on the said clamp halves and said plates, and heating means associated with at least one of said plates, whereby said plates may be slidingly inserted into, or removed from, said clamp halves so that said hair curling unit may be configured for use with either said first or said second surfaces.
Claim 6
Dependent Claim
24 words
In a hair curling unit as set forth in claim 3, that improvement including detent means in said rails for engaging with said plates.
Claim 7
Dependent Claim
105 words
A reversible crimper-straightener for hair including a handle, a pair of pivoted clamp halves secured to said handle, a pair of reversible plates, each said plate including a crimping surface on one side thereof and a flattening surface on the opposite side thereof, means for securing one of said plates within one of said clamp halves and the other of said plates within the other of said clamp halves, said securing means being reversible so that, alternatively, said crimping surfaces of said straightening surfaces face and are proximate to one another, whereby said crimper may alternatively be used for either crimping or straightening of hair.
Claim 8
Dependent Claim
105 words
A reversible crimper-straightener for hair including a handle, a pair of pivoted clamp halves secured to said handle, a pair of reversible plates, each said plate including a crimping surface on one side thereof and a flattening surface on the opposite side thereof, means for securing one of said plates within one of said clamp halves and the other of said plates within the other of said clamp halves, said securing means being reversible so that, alternatively, said crimping surfaces of said straightening surfaces face and are proximate to one another, whereby said crimper may alternatively be used for either crimping or straightening of hair.
Claim 9
Dependent Claim
169 words
A reversible crimper-straightener for hair including a handle, a pair of pivoted clamp halves secured to said handle, a pair of reversible plates, each said plate including a crimping surface on one side thereof and a flattening surface on the opposite side thereof, means for securing one of said plates within one of said clamp halves and the other of said plates within the other of said clamp halves, said securing means being reversible so that, alternatively, said crimping surfaces or said straightening surfaces face and are proximate to one another, and said securing means including a longitudinally extending rail on each side of each of said plates and a corresponding receiving track on each side of each of said clamp halves, and locking means for holding said rails within their respective said tracks, whereby said plates may be slidingly removed from their respective said clamp halves, reversed, and reinserted into said clamp halves, so that said crimper may alternatively be used for either crimping or straightening of hair.
Claim 10
Dependent Claim
169 words
A reversible crimper-straightener for hair including a handle, a pair of pivoted clamp halves secured to said handle, a pair of reversible plates, each said plate including a crimping surface on one side thereof and a flattening surface on the opposite side thereof, means for securing one of said plates within one of said clamp halves and the other of said plates within the other of said clamp halves, said securing means being reversible so that, alternatively, said crimping surfaces or said straightening surfaces face and are proximate to one another, and said securing means including a longitudinally extending rail on each side of each of said plates and a corresponding receiving track on each side of each of said clamp halves, and locking means for holding said rails within their respective said tracks, whereby said plates may be slidingly removed from their respective said clamp halves, reversed, and reinserted into said clamp halves, so that said crimper may alternatively be used for either crimping or straightening of hair.
Claim 11
Dependent Claim
16 words
A crimper-straightener as set forth in claim 6 in which said locking means are spring-pressed detents.
Claim 12
Dependent Claim
