Abstract
Abstract An electrical circuit component lead cutter including a slotted track for receiving the downwardly extending component wire leads and conveying them into operative engagement with a shearing mechanism which trims the leads to a selected length. The track is inclined at an angle relative to the horizontal so that the components are gravity fed along the track and between a pair of shearing edges which require no precise registration to effect their trimming function.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
178 words
An electrical component lead cutting apparatus, comprising: a chassis; a pair of elongated rails supported by said chassis and disposed in side-by-side spaced relationship to provide a lead receiving slot therebetween, said rails forming a track for transporting the bodies oF electrical components having leads to be trimmed, the leads projecting through said slot as said component moves along said track; shearing means supported by said chassis and disposed beneath said rails for shearing said leads as said components move along said track, said shearing means including a motor, means forming a fixed shearing edge, and means driven by said motor forming a moving shearing edge which cooperates with said fixed shearing edge to sever the component leads as the components move along said track, said motor including an eccentric drive means which is operative to cause said moving shearing edge to move in oscillatory fashion relative to said fixed shearing edge; and adjustment means for enabling the spacing between said track and said shearing means to be varied so that the lead cut length can be selected.
Claim 2
Dependent Claim
178 words
An electrical component lead cutting apparatus, comprising: a chassis; a pair of elongated rails supported by said chassis and disposed in side-by-side spaced relationship to provide a lead receiving slot therebetween, said rails forming a track for transporting the bodies oF electrical components having leads to be trimmed, the leads projecting through said slot as said component moves along said track; shearing means supported by said chassis and disposed beneath said rails for shearing said leads as said components move along said track, said shearing means including a motor, means forming a fixed shearing edge, and means driven by said motor forming a moving shearing edge which cooperates with said fixed shearing edge to sever the component leads as the components move along said track, said motor including an eccentric drive means which is operative to cause said moving shearing edge to move in oscillatory fashion relative to said fixed shearing edge; and adjustment means for enabling the spacing between said track and said shearing means to be varied so that the lead cut length can be selected.
Claim 3
Dependent Claim
40 words
An electrical component lead cutting apparatus as recited in claim 1 wherein one end of said track is disposed higher than the other end thereof so that the components are caused by their own weight to move along said track.
Claim 4
Dependent Claim
36 words
An electrical component lead cutting apparatus as recited in claim 1 wherein said track includes a third rail disposed in side-by-side spaced relationship with one of said pair of rails to form another lead receiving slot.
Claim 5
Dependent Claim
50 words
An electrical component lead cutting apparatus as recited in claim 3 wherein said shearing means includes a motor, means forming a pair of fixed shearing edges, and means forming a pair of moving shearing edges which cooperate with said fixed shearing edges to sever component leads extending through said slots.
Claim 6
Dependent Claim
35 words
An electrical component lead cutting apparatus as recited in claim 4 wherein said motor includes an eccentric drive means for driving said moving shearing edges in an oscillatory fashion relative to said fixed shearing edges.
Claim 7
Dependent Claim
44 words
An electrical component lead cutting apparatus as recited in claim 1 and further including an elongated guide member disposed above said track and operative to engage said component bodies to restrain them from moving vertically with respect to said track as they move therealong.
Claim 8
Dependent Claim
61 words
An electrical component lead cutting apparatus as recited in claim 1 wherein said adjustment means includes bracket means affixed to said chassis, said bracket means having parallel slots provided therein which are angularly disposed relative to said track, and means affixed to said rails and extending through said slots whereby all selected positions of said track lie parallel to each other.
Claim 9
Dependent Claim
49 words
An electrical component lead cutting apparatus as recited in claim 1 which further includes a first receptacle disposed proximate the component loading end of said track for receiving lead scraps and a second receptacle disposed proximate the component discharge end of said track for receiving the lead trimmed components.
