Abstract
Abstract An apparatus for punching or shearing work members by tool elements which are supported in a holder, with one of the tool elements movable toward and away from the other. The holder is supported in a frame in which a work member is guided between the tool elements. The holder is resiliently supported in the frame so that during a work operation the actuated tool element will first engage the work member and then the holder will move to bring the other tool element into engagement with the work member and the work operation is then completed by continuing the actuation of the actuated tool element.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
175 words
In an apparatus for operating on a work member by first and second tool element means disposed on opposite sides of the work member; holder means supporting said tool element means in opposed spaced relation, drive means in said holder means operable for moving said first tool element means toward said second tool element means for a work operation and then away from said second tool element means after a work operation, a punching frame, integrally only C-formed work member guide means in the frame for supporting a work member to be operated between said tool element means, and support means supporting said holder means in said frame for movement of the holder means in the frame in a direction parallel to the direction of movement of said first tool element means, said support means permitting movement of said holder means in the frame when said first tool element means engages said work member during a work operation thereby to cause said second tool element means also to move into engagement with said work member.
Claim 2
Dependent Claim
175 words
In an apparatus for operating on a work member by first and second tool element means disposed on opposite sides of the work member; holder means supporting said tool element means in opposed spaced relation, drive means in said holder means operable for moving said first tool element means toward said second tool element means for a work operation and then away from said second tool element means after a work operation, a punching frame, integrally only C-formed work member guide means in the frame for supporting a work member to be operated between said tool element means, and support means supporting said holder means in said frame for movement of the holder means in the frame in a direction parallel to the direction of movement of said first tool element means, said support means permitting movement of said holder means in the frame when said first tool element means engages said work member during a work operation thereby to cause said second tool element means also to move into engagement with said work member.
Claim 3
Dependent Claim
28 words
An apparatus according to claim 1 in which said support means comprises centering spring means and said work member is disposed about midway between said tool element means.
Claim 4
Dependent Claim
33 words

Claim 5
Dependent Claim
53 words
An apparatus according to claim 1 in which said holder means comprises lateral extension means thereon, box means into which said extension means extends, said support means including centering springs disposed in said box means on opposite sides of said extension means, and connecting means adjustably connecting said box means to said frame.
Claim 6
Dependent Claim
50 words
An apparatus according to claim 1 in which said tool element means are spaced in the vertical direction and said first tool element means and said holder means are moveable in the vertical direction, and counterweight means in said frame connected to said holder means and counterbalancing the weight thereof.
Claim 7
Dependent Claim
35 words
An apparatus according to claim 1 which includes feeler means in said frame engageable with said work member and acting in a direction perpendicular to the direction of movement of said first tool element means.
Claim 8
Dependent Claim
214 words
In an apparatus for operating on a work member by first and second tool element means disposed on opposite sides of the work member; holder means supporting said tool element means in opposed spaced relation, drive means in said holder means operable for moving said first tool element means toward said second tool element means for a work operation and then away from said second tool element means after a work operation, a frame, work member guide means in the frame for supporting a work member to be operated between said tool element means, and support means supporting said holder means in said frame for movement of the holder meanS in the frame in a direction parallel to the direction of movement of said first tool element means, said support means permitting movement of said holder means in the frame when said first tool element means engages said work member during a work operation thereby to cause said second tool element means also to move into engagement with said work member, said holder means comprising a pair of U-shaped holders each having a first and a second tool element therein, said holders being serially arranged in the direction of movement of the work member in the frame and being reversed relative to one another.
Claim 9
Dependent Claim
214 words
In an apparatus for operating on a work member by first and second tool element means disposed on opposite sides of the work member; holder means supporting said tool element means in opposed spaced relation, drive means in said holder means operable for moving said first tool element means toward said second tool element means for a work operation and then away from said second tool element means after a work operation, a frame, work member guide means in the frame for supporting a work member to be operated between said tool element means, and support means supporting said holder means in said frame for movement of the holder meanS in the frame in a direction parallel to the direction of movement of said first tool element means, said support means permitting movement of said holder means in the frame when said first tool element means engages said work member during a work operation thereby to cause said second tool element means also to move into engagement with said work member, said holder means comprising a pair of U-shaped holders each having a first and a second tool element therein, said holders being serially arranged in the direction of movement of the work member in the frame and being reversed relative to one another.
Claim 10
Dependent Claim
36 words
