Abstract
Abstract Appaatus for cutting and forming leads of electrical components utilizes a movable block reciprocally driven relative to a fixed block having a pair of spaced shearing surfaces that cooperate with a pair of cutters carried by the movable block to cut the ends of an electrical component supported crosswise to the cutters on a component carrying section of the movable block. The component carrying section has a stop to catch the inner ends of the component after the cutting operation and to hold the component as the component carrying section moves between a pair of opposing lead forming surfaces on the fixed block.

Total Claims: 16
Claim 1
Independent Claim
222 words
An apparatus for cutting and forming the axial leads of electrical components comprising a base member, a slide housing supported on said base, a movable block slidably supported in a passageway formed in said housing, drive means for reciprocally moving said movable block in a straight line path, said movable block including a component carrying section extending forwardly of said passageway disposed between a pair of parallel cutters, said component carrying section having a pair of skid surfaces for supporting the leads of the component and stop means located behind the plane of the cutting edges for said cutters for engaging the inner ends of the components, a fixed block mounted on said base member, said fixed block having a pair of spaced shearing surfaces disposed in the path of said cutters and spaced apart a distance slightly less than said cutters and having a pair of opposing forming surfaces disposed in the path of said component carrying section and spaced apart a distance slightly greater than said pair of skid surfaces for bending the leads as said section passes therebetween on its forward stroke, and eject means for engaging and holding the electrical component against movement during the return stroke of said movable block to permit said component to drop as the forward edge of said component carrying section passes thereby.
Claim 2
Independent Claim
222 words
An apparatus for cutting and forming the axial leads of electrical components comprising a base member, a slide housing supported on said base, a movable block slidably supported in a passageway formed in said housing, drive means for reciprocally moving said movable block in a straight line path, said movable block including a component carrying section extending forwardly of said passageway disposed between a pair of parallel cutters, said component carrying section having a pair of skid surfaces for supporting the leads of the component and stop means located behind the plane of the cutting edges for said cutters for engaging the inner ends of the components, a fixed block mounted on said base member, said fixed block having a pair of spaced shearing surfaces disposed in the path of said cutters and spaced apart a distance slightly less than said cutters and having a pair of opposing forming surfaces disposed in the path of said component carrying section and spaced apart a distance slightly greater than said pair of skid surfaces for bending the leads as said section passes therebetween on its forward stroke, and eject means for engaging and holding the electrical component against movement during the return stroke of said movable block to permit said component to drop as the forward edge of said component carrying section passes thereby.
Claim 3
Dependent Claim
78 words
An apparatus as defined in claim 1, wherein said fixed block comprises a pair of inner and outer upstanding legs disposed crosswise to the linear movement of said movable block such that said cutters move between adjacent inner and outer legs and said component carrying section moves between said inner pair of legs, whereby said outer corners of said inner legs define said shearing surfaces and said inner corners and opposing lateral surfaces define said lead forming surfaces.
Claim 4
Dependent Claim
33 words
An apparatus as defined in claim 2, wherein said inner pair of legs include wedge-shaped notches formed in said inner corners in the path of component''s leads to assist in bending the leads.
