Abstract
Abstract A curling iron has a barrel and a hair-clamping arm pivotally mounted thereon for movement between an elevated position in which it projects angularly and forwardly relative to the barrel and a lowered hair-clamping position in which it is disposed alongside the barrel. A sleeve extends around the barrel and can be rotated and/or moved axially to cause movement of the hair-clamping arm into its elevated position against the action of a spring biassing that arm into its lowered position.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
115 words
A curling iron having a generally cylindrical barrel, an electrical heating element within said barrel, and an electrical supply cord therefor, and wherein the improvement comprises: a hair-clamping arm pivotally mounted on said barrel for movement between an elevated position in which it projects angularly and forwardly relative to said barrel and a lowered position in which it is disposed alongside said barrel in close proximity thereto; a spring means acting on said hair-clamping arm and urging that arm into said lowered position thereof; and a manually operable arm-lifting sleeve extending around said barrel and movable relative thereto to move said hair-clamping arm toward said elevated position thereof against the action of said spring means.
Claim 2
Dependent Claim
115 words
A curling iron having a generally cylindrical barrel, an electrical heating element within said barrel, and an electrical supply cord therefor, and wherein the improvement comprises: a hair-clamping arm pivotally mounted on said barrel for movement between an elevated position in which it projects angularly and forwardly relative to said barrel and a lowered position in which it is disposed alongside said barrel in close proximity thereto; a spring means acting on said hair-clamping arm and urging that arm into said lowered position thereof; and a manually operable arm-lifting sleeve extending around said barrel and movable relative thereto to move said hair-clamping arm toward said elevated position thereof against the action of said spring means.
Claim 3
Dependent Claim
18 words
A curling iron as claimed in claim 1 and in which said arm-lifting sleeve completely encircles said barrel.
Claim 4
Dependent Claim
40 words
A curling iron as claimed in claim 2 and in which said arm-lifting sleeve is adapted to move said hair-clamping arm toward said elevated position thereof on axial movement of said sleeve relative to said barrel in one axial direction.
Claim 5
Dependent Claim
37 words
A curling iron as claimed in claim 3 and in which said arm-lifting sleeve is adapted to move said hair-clamping arm toward said elevated position thereof on rearward axial movement of said sleeve relative to said barrel.
Claim 6
Dependent Claim
34 words
A curling iron as claimed in claim 2 and in which said arm-lifting sleeve is adapted to move said hair-clamping arm toward said elevated position thereof on rotation of said sleeve about said barrel.
Claim 7
Dependent Claim
41 words
A curling iron as claimed in claim 5 and in which said arm-lifting sleeve is adapted also to move said hair-clamping arm toward said elevated position thereof on axial movement of said sleeve relative to said barrel in one axial direction.
Claim 8
Dependent Claim
37 words
A curling iron as claimed in claim 6 and in which said arm-lifting sleeve is adapted to move said hair-clamping arm toward said elevated position thereof on rearward axial movement of said sleeve relative to said barrel.
Claim 9
Dependent Claim
77 words
A curling iron as claimed in claim 7 and which comprises an axially movable linkage within said curling iron axially movable therewithin to engage said hair-clamping arm and to move said arm toward said elevated position thereof on forward axial movement of said linkage, said linkage and said arm-lifting sleeve being provided with cooperating cam surfaces whereby said linkage is moved axially forwardly during both rotation and forward axial movement of said sleeve relative to said barrel.
