Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
176 words
A method of removing a staple from an object comprising the steps of: providing a device for removing said staple that includes a first member and a second member that is movably secured to said first member, pivot means connecting said first and second members, a first clamping element projecting generally outwardly from said first member, and second clamping element projecting generally outwardly from said second member for cooperation with said first clamping element for engaging said staple between said first and second clamping elements, said first member and said second member each having teeth means adjacent a first end of the longitudinal axis of said staple remover for the initial removal of said staple, positioning a portion of said staple intermediate said first and second projecting outwardly clamping elements, relatively moving said first clamping element toward said second clamping element to engage said staple between said first and second clamping elements, and moving said staple remover away from said object in which said staple is inserted to effect removal of said staple from said object.
Claim 2
Independent Claim
176 words
A method of removing a staple from an object comprising the steps of: providing a device for removing said staple that includes a first member and a second member that is movably secured to said first member, pivot means connecting said first and second members, a first clamping element projecting generally outwardly from said first member, and second clamping element projecting generally outwardly from said second member for cooperation with said first clamping element for engaging said staple between said first and second clamping elements, said first member and said second member each having teeth means adjacent a first end of the longitudinal axis of said staple remover for the initial removal of said staple, positioning a portion of said staple intermediate said first and second projecting outwardly clamping elements, relatively moving said first clamping element toward said second clamping element to engage said staple between said first and second clamping elements, and moving said staple remover away from said object in which said staple is inserted to effect removal of said staple from said object.
Claim 3
Dependent Claim
99 words
The method of claim 1 including positioning said teeth means between the crossbar of said staple and said object in which said staple is inserted, moving said teeth means on said first member toward said second member and said teeth means on said second member toward said first member, whereby said staple will be at least partially removed from the object by camming, and moving said teeth means on said first member away from said second member and said teeth means on said second member away from said first member, whereby said staple will disengage from said staple remover.
Claim 4
Dependent Claim
17 words
The method of claim 2 including pivotally moving said first clamping element toward said second clamping element.
Claim 5
Dependent Claim
20 words

Claim 6
Dependent Claim
19 words
The method of claim 4 including biasing said first clamping element from said second clamping element with spring means.
Claim 7
Dependent Claim
21 words
The method of claim 4 including biasing said first clamping element from said second clamping element with a resilient compressible material.
Claim 8
Dependent Claim
26 words
The method of claim 4 including projecting generally transversely said first clamping element from said first member and said second clamping element from said second member.
Claim 9
Dependent Claim
26 words
The method of claim 4 including projecting generally transversely said first and second clamping elements from a position intermediate said first end and said pivot means.
Claim 10
