Abstract
Abstract A hair curling device including a handle providing a source of heated air to a perforate cylindrical fixed jaw attached thereto and having a movable jaw pivotally mounted relative to the fixed jaw, with the pivoting action being effected by a lever which extends generally lengthwise of the handle and which is located on the opposite side of the handle from the movable jaw, a linkage between the lever and the movable jaw extending through a mounting connector which mounts the fixed jaw on the handle and includes a spring for biasing the movable jaw into clamped relationship with the fixed jaw. A hair curling device of the foregoing type in which the jaws, lever, and linkage are mounted on a mounting connector which may be selectively mounted and demounted from a handle.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
150 words
A hair curling device wherein the improvement comprises: a fixed jaw having front and rear ends; a movable jaw having front and rear ends, with its front end free and its rear end pivotally mounted relative to said rear end of said fixed jaw on one side thereof; an elongated lever having front and rear ends and an intermediate portion located adjacent but rearwardly of its front end, with said intermediate portion pivotally mounted relative to said rear end of said fixed jaw on the side thereof opposite said one side; linkage means connecting said front end of said lever with said rear end of said movable jaw to pivot said movable jaw toward and away from said fixed jaw upon actuation of said lever; and resilient means operatively associated with said linkage means for biasing said movable jaw and said front end of said lever toward said fixed jaw.
Claim 2
Dependent Claim
150 words
A hair curling device wherein the improvement comprises: a fixed jaw having front and rear ends; a movable jaw having front and rear ends, with its front end free and its rear end pivotally mounted relative to said rear end of said fixed jaw on one side thereof; an elongated lever having front and rear ends and an intermediate portion located adjacent but rearwardly of its front end, with said intermediate portion pivotally mounted relative to said rear end of said fixed jaw on the side thereof opposite said one side; linkage means connecting said front end of said lever with said rear end of said movable jaw to pivot said movable jaw toward and away from said fixed jaw upon actuation of said lever; and resilient means operatively associated with said linkage means for biasing said movable jaw and said front end of said lever toward said fixed jaw.
Claim 3
Dependent Claim
65 words
The hair curling device of claim 1 wherein said fixed jaw is hollow and perforated, with its rear end open and enlarged to form a hollow mounting connector for selective attachment to a handle, and its front end closed; and said movable jaw is perforated, with its inner surface complementary to and normally biased into mating engagement with the outer surface of said fixed jaw.
Claim 4
Dependent Claim
123 words
The hair curling device of claim 1 wherein said linkage means include a first pivotal connection effectively located between said rear end of said fixed jaw and said rear end of said movable jaw on said one side, a second pivotal connection effectively located between said rear end of said fixed jaw and said intermediate portion of said lever on said opposite side, an elongated link extending transversely of said rear end of said fixed jaw, a third pivotal connection between said rear end of said movable jaw and one end of said link proximate said first pivotal connection, and a fourth pivotal connection between said front end of said lever and the opposite end of said link proximate said second pivotal connection.
Claim 5
Dependent Claim
107 words
The hair curling device of claim 3 wherein said linkage means include an arm having a front end attached to said rear end of said movable jaw, a rear end forming said third pivotal connection with said one end of said link, and an intermediate portion, an outstanding front trunnion attached to said rear end of said fixed jaw on said one side and forming said first pivotal connection with said intermediate portion of said arm, and an outstanding rear trunnion attached to said rear end of said fixed jaw on said opposite side and forming said second pivotal connection with said intermediate portion of said lever.
Claim 6
Dependent Claim
38 words
The hair curling device of claim 1 wherein said resilient means include a helical spring having one end effectively secured to said linkage means and its opposite end effectively bearing against said rear end of said fixed jaw.
Claim 7
Dependent Claim
164 words
The hair curling device of claim 1 wherein said fixed jaw is hollow and perforated, with its rear end open and enlarged to form a hollow mounting connection for selective attachment to a handle, and its front end closed; said movable jaw is perforated, with its inner surface complementary to and normally biased into mating engagement with the outer surface of said fixed jaw; and said linkage means include a first pivotal connection between said mounting connector and said rear end of said movable jaw on said one side, a second pivotal connEction between said mounting connector and said intermediate portion of said lever on said opposite side, an elongated link extending transversely of said mounting connector, a third pivotal connection between said rear end of said movable jaw and one end of said link proximate said first pivotal connection, and a fourth pivotal connection between said front end of said lever and the opposite end of said link proximate said second pivotal connection.
Claim 8
Dependent Claim
91 words
The hair curling device of claim 1 wherein said fixed jaw is hollow and perforated, with its rear end open and enlarged to form a hollow mounting connector for selective attachment to a handle and its front end closed; said movable jaw is perforated, with its inner surface complementary to and normally biased into mating engagement with the outer surface of said fixed jaw; and said resilient means include a helical spring having one end effectively secured to said linkage means and its opposite end effectively biasing against said mounting connector.
Claim 9
Dependent Claim
157 words
The hair curling device of claim 1 wherein said linkage means include a first pivotal connection effectively located between said rear end of said fixed jaw and said rear end of said movable jaw on said one side, a second pivotal connection effectively located between said rear end of said fixed jaw and said intermediate portion of said lever on said opposite side, an elongated link extending transversely of said rear end of said fixed jaw, a third pivotal connection between said rear end of said movable jaw and one end of said link proximate said first pivotal connection, and a fourth pivotal connection between said front end of said lever and the opposite end of said link proximate said second pivotal connection; and said resilient means include a helical spring surrounding said link and having one end effectively secured to said link and its opposite end effectively bearing against said rear end of said fixed jaw.
Claim 10
Dependent Claim
197 words
The hair curling device of claim 1 wherein said fixed jaw is hollow and perforated, with its rear end open and enlarged to form a hollow mounting connector for selective attachment to a handle and its front end closed, said movable jaw is perforated, with its inner surface complementary to and normally biased into mating engagement with the outer surface of said fixed jaw; said linkage means include a first pivotal connection between said mounting connector and said rear end of said movable jaw on said one side, a second pivotal connection between said mounting connector and said intermediate portion of said lever on said opposite side, an elongated link extending transversely through said mounting connector, a third pivotal connection between said rear end of said movable jaw and one end of said link proximate said first pivotal connection, and a fourth pivotal connection between said front end of said lever and the opposite end of said link proximate said second pivotal connection; and said resilient means include a helical spring surrounding said link within said mounting connector and having one end effectively secured to said link and its opposite end effectively bearing against said mounting connector.
