Abstract
Abstract Metal stock sequentially cut, folded and clinched about a pair of electrical leads in a stapling machine into which the stock is fed. A pair of relatively movable, metal deforming elements are advanced along a track by link connections to a common crank pin rotated by a drive shaft during each cycle to perform the metal deforming operations with sufficient impact.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
122 words
In a work deforming machine through which stock is adapted to be fed along a work path, a pair of work deforming elements, track means for guiding movement of said elements through predetermined strokes along parallel paths intersecting said work path, a drive member, bearing means rotationally supporting the drive member, drive means drivingly connecting said drive member to one of the work deforming elements for sequentially performing at least two operations during movement toward one end of said strokes, and linkage means connecting the drive means to the other of said work deforming elements for displacement relative to said one of the elements to perform a third operation as said one of the elements approaches said one end of the strokes.
Claim 2
Dependent Claim
122 words
In a work deforming machine through which stock is adapted to be fed along a work path, a pair of work deforming elements, track means for guiding movement of said elements through predetermined strokes along parallel paths intersecting said work path, a drive member, bearing means rotationally supporting the drive member, drive means drivingly connecting said drive member to one of the work deforming elements for sequentially performing at least two operations during movement toward one end of said strokes, and linkage means connecting the drive means to the other of said work deforming elements for displacement relative to said one of the elements to perform a third operation as said one of the elements approaches said one end of the strokes.
Claim 3
Dependent Claim
32 words
The combination of claim 1 wherein said one of the elements slidably mounts the other of the elements and includes means for limiting said relative displacement of said other of the elements.
Claim 4
Dependent Claim
43 words
The combination of claim 1 wherein said drive member comprises a crank disc from which the drive means and the linkage means extend axially, said bearing means directly engaging the crank disc in close adjacency to said paths of the work deforming elements.
Claim 5
Dependent Claim
25 words
The combination of claim 3 wherein said work deforming elements have planar end faces aligned with each other at said one end of the strokes.
Claim 6
Dependent Claim
28 words
The combination of claim 4 including a stationary member positioned in close adjacency to the end faces of the deforming elements at said one end of the strokes.
Claim 7
Dependent Claim
25 words
The combination of claim 1 wherein said work deforming elements have planar end faces aligned with each other at said one end of the strokes.
Claim 8
Dependent Claim
28 words
The combination of claim 6 including a stationary member positioned in close adjacency to the end faces of the deforming elements at said one end of the strokes.
