US3986533A — Mechanism for clinching leads inwardly or outward…

Claim 1

Independent Claim 131 words

Mechanism for cutting and clinching component leads projecting from a wiring board or the like comprising a support having a guideway parallel to the board, at least one pair of cut-clinch assemblies slidable in the guideway, each of said assemblies comprising an anvil including a stationary shear bar for receiving the projecting leads and a relatively movable shear cooperative with the shear bar, and power means including a member for restraining the assemblies against relative movement in the guideway and operable to cause the shears to trim the leads and then clinch the shorn leads inwardly, said member being shiftable to an alternate operating position whereby said assemblies are yieldingly separable laterally in the guideway to enable the shear bars to clinch the leads outwardly following their trimming by said shears.

Claim 2

Dependent Claim 131 words

Mechanism for cutting and clinching component leads projecting from a wiring board or the like comprising a support having a guideway parallel to the board, at least one pair of cut-clinch assemblies slidable in the guideway, each of said assemblies comprising an anvil including a stationary shear bar for receiving the projecting leads and a relatively movable shear cooperative with the shear bar, and power means including a member for restraining the assemblies against relative movement in the guideway and operable to cause the shears to trim the leads and then clinch the shorn leads inwardly, said member being shiftable to an alternate operating position whereby said assemblies are yieldingly separable laterally in the guideway to enable the shear bars to clinch the leads outwardly following their trimming by said shears.

Claim 3

Dependent Claim 13 words

Mechanism as in claim 1 wherein said shiftable member is a latch pin.

Claim 4

Dependent Claim 80 words

Mechanism as in claim 2 wherein the power means comprises a fluid pressure operated piston rod and linkage actuatable by the rod for operating the shears, said latch pin being insertable in said support to cause the shears to trim the leads and then clinch them inwardly, and the latch pin being alternatively connectable to the rod to cause other linkage to force the shear bars apart when the leads have been shorn whereby the shorn leads are clinched outwardly.

Claim 5

Dependent Claim 92 words

Mechanism for cutting and clinching component leads projecting from a wiring board comprising a support, at least one pair of cut-clinch assemblies mounted on the support for relative lateral movement together and apart, each of said assemblies including a pair of cooperative shears either one of which shears is operable as a clinching means when the leads have been shorn thereby, and power means operable in optional modes for causing one of the shears to clinch the shorn leads outwardly and the other of the shears to clinch the shorn leads inwardly.

Claim 6

Dependent Claim 92 words

Mechanism for cutting and clinching component leads projecting from a wiring board comprising a support, at least one pair of cut-clinch assemblies mounted on the support for relative lateral movement together and apart, each of said assemblies including a pair of cooperative shears either one of which shears is operable as a clinching means when the leads have been shorn thereby, and power means operable in optional modes for causing one of the shears to clinch the shorn leads outwardly and the other of the shears to clinch the shorn leads inwardly.

Claim 7

Dependent Claim 120 words

Cutting and clinching mechanism operable on spaced, projecting leads of a component comprising a pair of laterally opposed cut-clinch assemblies, each of the assemblies comprising a laterally movable support, lead trimming and clinching means operable in an inclined guideway of the support, linkage connected to each of the lead trimming and clinching means for simultaneously causing the leads to be cut before they are clinched, power means for actuating the linkage, optional means for releasably latching the cut-clinch assemblies against lateral movement when the power means effects lead clinching in one lateral direction, and other mechanism operable by the power means when said optional means has released said assemblies from latched relation to effect lead clinching in another lateral direction.

Claim 8

Dependent Claim 120 words

Cutting and clinching mechanism operable on spaced, projecting leads of a component comprising a pair of laterally opposed cut-clinch assemblies, each of the assemblies comprising a laterally movable support, lead trimming and clinching means operable in an inclined guideway of the support, linkage connected to each of the lead trimming and clinching means for simultaneously causing the leads to be cut before they are clinched, power means for actuating the linkage, optional means for releasably latching the cut-clinch assemblies against lateral movement when the power means effects lead clinching in one lateral direction, and other mechanism operable by the power means when said optional means has released said assemblies from latched relation to effect lead clinching in another lateral direction.

Claim 9

Independent Claim 123 words

A device for cutting and clinching the projecting ends of component leads comprising a pair of right-triangular supports having their vertical sides adjacent and laterally movable apart, a fixed shear bar and relatively slidable shear mounted on the inclined sides, respectively, of the supports, fluid pressure operating means including a piston rod operatively connected to said slidable shears to effect trimming of the leads and inward clinching thereof when said vertical sides are proximate, means yieldingly restraining said supports against relative lateral separation, and mechanism optionally connectable to the piston rod for forcing the shear bars laterally apart against the influence of said restraining means whereby the leads, when shorn by the slidable shears, are clinched outwardly by lateral separation of, said bars.

Claim 10

Independent Claim 123 words

A device for cutting and clinching the projecting ends of component leads comprising a pair of right-triangular supports having their vertical sides adjacent and laterally movable apart, a fixed shear bar and relatively slidable shear mounted on the inclined sides, respectively, of the supports, fluid pressure operating means including a piston rod operatively connected to said slidable shears to effect trimming of the leads and inward clinching thereof when said vertical sides are proximate, means yieldingly restraining said supports against relative lateral separation, and mechanism optionally connectable to the piston rod for forcing the shear bars laterally apart against the influence of said restraining means whereby the leads, when shorn by the slidable shears, are clinched outwardly by lateral separation of, said bars.

Claim 11

Dependent Claim 36 words

A device as in claim 6 wherein said mechanism includes a pair of toggle links corresponding ends of which are connected to the supports and opposite ends of the links are operatively connected to the rod.
