Claims Analysis

Total Claims: 19
Claim 1
Independent Claim 121 words
A measuring device comprising: (a) a base for positioning an object to be measured; and (b) a measuring apparatus joined to said base, said measuring apparatus having an arm member divided into a first and second portion by a fulcrum, said first portion having the center of gravity adjacent a first end thereof farthest from the fulcrum, said second portion having weight means provided thereon, said weight applying a weight to the second portion such that said second portion has the center of gravity adjacent a second end thereof farthest from said fulcrum, and said fulcrum thereinbetween said first and second centers of gravity and wherein said first and second centers of gravity and the fulcrum lie in a common line.
Claim 2
Dependent Claim 121 words
A measuring device comprising: (a) a base for positioning an object to be measured; and (b) a measuring apparatus joined to said base, said measuring apparatus having an arm member divided into a first and second portion by a fulcrum, said first portion having the center of gravity adjacent a first end thereof farthest from the fulcrum, said second portion having weight means provided thereon, said weight applying a weight to the second portion such that said second portion has the center of gravity adjacent a second end thereof farthest from said fulcrum, and said fulcrum thereinbetween said first and second centers of gravity and wherein said first and second centers of gravity and the fulcrum lie in a common line.
Claim 3
Dependent Claim 23 words
A measuring device according to claim 1 wherein said measuring apparatus is movable mounted on an upwardly extending member joined to said base.
Claim 4
Dependent Claim 40 words
A measuring device according to claim 1 wherein said arm member includes a stylus coupled thereto adjacent said end of said first portion and a weight support rod coupled to said end said second portion and supporting said weight means.
Claim 5
Dependent Claim 83 words
A measuring device according to claim 1 wherein said arm member comprises a section having a generally L-shaped configuration, a rod-like member having a stylus holding member joined to said section and extending in a first direction, said first center of gravity located between said section and said rod-like member, and a weight support rod joined to said section and extending in a direction opposite to said rod-like member, said second center of gravity located between said section and said weight support rod.
Claim 6
Dependent Claim 22 words
A measuring device according to claim 1 wherein said arm member is joined to a selectively movable member in said measuring apparatus.
Claim 7
Dependent Claim 24 words
A measuring device according to claim 5 wherein said selectively movable member includes means for moving said arm member in a generally horizontal direction.
Claim 8
Dependent Claim 41 words
A measuring device according to claim 5 wherein said movable member comprises a generally cylindrical member coupled to a gear member such that upon activation of said gear member, said movable member moves said arm member in a generally vertical direction.
Claim 9
Dependent Claim 21 words
A measuring device according to claim 1 wherein said apparatus includes means for moving said arm member in a predetermined direction.
Claim 10
Dependent Claim 178 words
A measuring device comprising: (a) a base for positioning an object to be measured; (b) upwardly extending mounting means joined to said base; and (c) a measuring apparatus joined to said mounting means such that said apparatus can be moved relative to said base, said apparatus comprising a main body with a movable member disposed therein configured to be moved from one end of said body to the other, said movable member comprising a cylindrically shaped member circumferentially disposed about a fixed shaft, and an arm member rotatably joined to said movable member forming a fulcrum therewith said arm member comprising a stylus mounted on a rod-like member at one end thereof and a weight support member at the other end thereof, said arm member configured such that a first center of gravity is formed between said fulcrum and said stylus and a second center of gravity is formed adjacent said weight support member whereby said fulcrum is intermediate said first and second centers of gravity and said centers of gravity and fulcrum lie in a common line.
Claim 11
Dependent Claim 178 words
A measuring device comprising: (a) a base for positioning an object to be measured; (b) upwardly extending mounting means joined to said base; and (c) a measuring apparatus joined to said mounting means such that said apparatus can be moved relative to said base, said apparatus comprising a main body with a movable member disposed therein configured to be moved from one end of said body to the other, said movable member comprising a cylindrically shaped member circumferentially disposed about a fixed shaft, and an arm member rotatably joined to said movable member forming a fulcrum therewith said arm member comprising a stylus mounted on a rod-like member at one end thereof and a weight support member at the other end thereof, said arm member configured such that a first center of gravity is formed between said fulcrum and said stylus and a second center of gravity is formed adjacent said weight support member whereby said fulcrum is intermediate said first and second centers of gravity and said centers of gravity and fulcrum lie in a common line.
Claim 12
Dependent Claim 23 words
A measuring device according to claim 9 wherein said movable member is configured to move said arm member in a generally horizontal direction.
Claim 13
Dependent Claim 23 words
A measuring device according to claim 9 wherein said movable member is coupled to a gear member for selectively moving said movable member.
Claim 14
Dependent Claim 17 words
A measuring device according to claim 11 wherein said gear member is driven by a motor means.
Claim 15
Dependent Claim 29 words
A measuring device according to claim 9 wherein said main body includes switch means configured to selectively engage said arm member for regulating the movement of said arm member.
Claim 16
Dependent Claim 49 words
A measuring device according to claim 9 wherein rotatable cam means is disposed on said main body adjacent said weight support member such that upon activation of said cam means, said weight support member is selectively engaged thereby causing said arm member to move in a generally vertical direction.
Claim 17
Dependent Claim 47 words
A measuring device according to claim 9 wherein said arm member is rotatably joined to an arm support member by bearing means, and said arm support member is fixedly joined to said movable member, said fulcrum being formed between said arm member and said arm support member.
Claim 18
Dependent Claim 21 words
A measuring device according to claim 9 including means for limiting the movement of said cylindrical member on said fixed shaft.
Claim 19
Dependent Claim 25 words
A measuring device according to claim 16 wherein said limiting means is activated when said cylindrical member moves a predetermined distance along said fixed shaft.
