Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
149 words
A tool for installing and removing an elongated wedge between flanges of a die-cutting mat to thereby enable urging said flanges tightly against associated holding surfaces provided on an associated rotary anvil supporting said mat, said tool comprising an elongated main structural body, a bearing surface on said body, a pin supported by said body and extending outwardly of said bearing surface, said pin being adapted to be received within a longitudinal opening in said wedge, and handle means fixed to said body and extending transverse thereto enabling easy grasping of said tool and the application of forces by said bearing surface substantially parallel to said pin and the application of forces by said pin transverse thereto to enable said installing and removing, said handle means comprising a first handle fixed to one end of said body and a second handle fixed to the opposite end of said body.
Claim 2
Dependent Claim
149 words
A tool for installing and removing an elongated wedge between flanges of a die-cutting mat to thereby enable urging said flanges tightly against associated holding surfaces provided on an associated rotary anvil supporting said mat, said tool comprising an elongated main structural body, a bearing surface on said body, a pin supported by said body and extending outwardly of said bearing surface, said pin being adapted to be received within a longitudinal opening in said wedge, and handle means fixed to said body and extending transverse thereto enabling easy grasping of said tool and the application of forces by said bearing surface substantially parallel to said pin and the application of forces by said pin transverse thereto to enable said installing and removing, said handle means comprising a first handle fixed to one end of said body and a second handle fixed to the opposite end of said body.
Claim 3
Dependent Claim
33 words
A tool as set forth in claim 1 in which said body has oppositely arranged end surfaces, one of which defines said bearing surface, said pin extending perpendicularly outwardly from said bearing surface.
Claim 4
Dependent Claim
27 words
A tool as set forth in claim 2 in which said pin is made as an integral part of said main body as a single piece construction.
Claim 5
Dependent Claim
22 words
A tool as set forth in claim 2 in which said pin is a separate member which is fixed to said body.
Claim 6
Dependent Claim
59 words
A tool as set forth in claim 2 in which said first handle comprises a substantially U-shaped member having a bight fixed transversely of said body closely adjacent said bearing surface and having a pair of arms extending outwardly from opposite ends of said bight with a grasping member being fixed adjacent the terminal outer ends of said arms.
Claim 7
Dependent Claim
43 words
A tool as set forth in claim 5 in which said second handle comprises a rod-like handle extending substantially perpendicular to said main body and approximately parallel to the outwardly extending arms of said first handle and having a reduced diameter central portion.
Claim 8
Dependent Claim
37 words
A tool as set forth in claim 5 in which said second handle comprises a rod-like handle having a bifurcate lowEr end portion defined by a pair of parallel arms arranged on opposite sides of said body.
Claim 9
Dependent Claim
27 words
A tool as set forth in claim 1 in which said body is made of metal and has a roughly rectangular cross-sectional configuration at any position therealong.
Claim 10
Dependent Claim
44 words
A tool as set forth in claim 1 said body has an angled configuration, the top portion of one of said handles being positioned in a different plane than the top portion of the other of said handles during normal useage of said tool.
