Abstract
Abstract Skin Fold Caliper having first and second relatively rigid arms which have one end of each of the first and second members connected to permit pivotal movement of the first and second arms with respect to each other so that the other ends of the first and second arms can be moved between open and closed positions. A gauge is carried by the first and second arms for giving an indication of the spacing between the other ends of the first and second arms. A spring-like member formed integral with one of the arms is utilized for applying a predetermined clamping pressure between the first and second arms to move the other ends of the first and second arms toward the closed position.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
160 words
In a skin fold caliper: first and second relatively rigid arms, means connecting one end of each of the first and second arms with respect to each other so that the other ends of said first and second arms can be moved between open and closed positions, cooperative gauge means carried by said first and second arms for giving an indication of the spacing between the other ends of said first and second arms, means carried by said first and second arms, a spring-like member associated with said last named means, said spring-like member having one end secured to one of said arms and having the other end free, a cooperative gauge means carried by said spring-like member and said one arm, registration arrows carried by said spring-like member and said one arm, and the arrow carried by said spring-like member is carried by a flag and said one arm is provided with a slot adapted to receive said flag.
Claim 2
Dependent Claim
160 words
In a skin fold caliper: first and second relatively rigid arms, means connecting one end of each of the first and second arms with respect to each other so that the other ends of said first and second arms can be moved between open and closed positions, cooperative gauge means carried by said first and second arms for giving an indication of the spacing between the other ends of said first and second arms, means carried by said first and second arms, a spring-like member associated with said last named means, said spring-like member having one end secured to one of said arms and having the other end free, a cooperative gauge means carried by said spring-like member and said one arm, registration arrows carried by said spring-like member and said one arm, and the arrow carried by said spring-like member is carried by a flag and said one arm is provided with a slot adapted to receive said flag.
Claim 3
Dependent Claim
51 words
The caliper of claim 1 wherein said means carried by said first and second arms is formed integral with one of said arms for applying a predetermined clamping force between the other ends of said arms to move the other ends of said first and second arms towards the closed position.
Claim 4
Dependent Claim
54 words
The caliper of claim 1 wherein said spring-like member is positioned so that it can be engaged by one finger of a hand while another finger of the same hand can be utilized to engage the other arm to apply the predetermined clamping force between the other ends of said first and second arms.
Claim 5
Dependent Claim
42 words
The caliper as in claim 1 wherein said cooperative gauge means carried by said spring-like member and said one arm comprises means for determining when said predetermined clamping force is being applied between said other ends of said first and second arms.
Claim 6
Dependent Claim
28 words
A caliper as in claim 1 together with means carried by the first and second arms for yieldably urging said first and second arms towards said open position.
Claim 7
Dependent Claim
26 words
A caliper as in claim 1 together with stop means carried by said one arm for preventing deflection of said spring-like member beyond a predetermined amount.
Claim 8
Dependent Claim
87 words
A caliper as in claim 1 wherein said cooperative gauge means carried by said first and second arms for indicating the spacing between the other ends of said first and second arms includes an arcuate member carried by one of said arms, the other of said arms having a slot formed therein and adapted to receive the arcuate gauge member and means carried by the other of said arms and said arcuate gauge member for limiting movement of said other arm with respect to said gauge member.
Claim 9
Dependent Claim
30 words
A caliper as in claim 7 wherein said gauge member is provided with a recess extending longitudinally thereof and a pointer carried by said other arm extending into said recess.
