Claim 12
Dependent Claim
19 words
The apparatus of claim 7 including said first and second clamping elements having cooperating surfaces that are substantially planar.
Claim 13
Dependent Claim
30 words
The apparatus of claim 11 including the planes of said first and second clamping elements being generally parallel when a staple is engaged between said first and second clamping elements.
Claim 14
Independent Claim
209 words
A device for removing a staple from an object comprising: a first member, a second member which is movably secured to said first member, pivot means connecting said first member and said second member, said first member having attached a first clamping element, said second member having a second clamping element for cooperation with said first clamping element in engaging a staple, said first member and said second member each having teeth means adjacent a first end of the longitudinal axis of said staple remover for initiating removal of said staple from the object, said first clamping element projecting from said first member and said second clamping element projecting from said second member, said first and second clamping elements projecting from a second end of the longitudinal axis of said staple remover, and said second clamping element having a generally angled section and a generally planar section and being attached to said second member, whereby positioning a portion of a staple intermediate said first and second clamping elements, relatively rotating said first and second clamping elements toward each other to engage said staple between said first and second clamping elements, and moving said staple removing device away from said object will effect removal of said staple from said object.
Claim 15
Independent Claim
209 words
A device for removing a staple from an object comprising: a first member, a second member which is movably secured to said first member, pivot means connecting said first member and said second member, said first member having attached a first clamping element, said second member having a second clamping element for cooperation with said first clamping element in engaging a staple, said first member and said second member each having teeth means adjacent a first end of the longitudinal axis of said staple remover for initiating removal of said staple from the object, said first clamping element projecting from said first member and said second clamping element projecting from said second member, said first and second clamping elements projecting from a second end of the longitudinal axis of said staple remover, and said second clamping element having a generally angled section and a generally planar section and being attached to said second member, whereby positioning a portion of a staple intermediate said first and second clamping elements, relatively rotating said first and second clamping elements toward each other to engage said staple between said first and second clamping elements, and moving said staple removing device away from said object will effect removal of said staple from said object.
Claim 16
Dependent Claim
