Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
156 words
A first apparatus for simultaneously cutting and clinching a row of aligned leads of a DIP type electronic component, said leads inserted in and projecting beneath a circuit board, said apparatus including: a housing; a cutter, said cutter mounted for translating on a first surface of said housing, said cutter having an aligned row of spaced slots therethrough, said row of slots being aligned transversely to the direction of said translation, said slots spaced apart to receive therein said projecting component leads; a cover fixedly attached to said housing and adjacent said cutter with sliding contact therebetween, said cover including a first cutting edge adjacent said cutter, said first cutting edge sliding across said row of slots when said cutter is translated; and means to translate said cutter, whereby said component leads projecting beneath said circuit board and received in said slots are cut against said first cutting edge and clinched when said cutter is translated.
Claim 2
Dependent Claim
156 words
A first apparatus for simultaneously cutting and clinching a row of aligned leads of a DIP type electronic component, said leads inserted in and projecting beneath a circuit board, said apparatus including: a housing; a cutter, said cutter mounted for translating on a first surface of said housing, said cutter having an aligned row of spaced slots therethrough, said row of slots being aligned transversely to the direction of said translation, said slots spaced apart to receive therein said projecting component leads; a cover fixedly attached to said housing and adjacent said cutter with sliding contact therebetween, said cover including a first cutting edge adjacent said cutter, said first cutting edge sliding across said row of slots when said cutter is translated; and means to translate said cutter, whereby said component leads projecting beneath said circuit board and received in said slots are cut against said first cutting edge and clinched when said cutter is translated.
Claim 3
Dependent Claim
88 words
The first apparatus of claim 1 further including: a second cutting edge, said second cutting edge located on said cutter; an anvil mounted on said housing, said anvil having a shearing surface spaced apart from said second cutting edge and said cover, said second cutting edge moving across said shearing surface when said cutter translates; whereby said component leads projecting beneath said circuit board and received between said shearing surface and said second cutting edge are cut against said shearing surface and clinched when said cutter is translated.
Claim 4
Dependent Claim
12 words
The first apparatus of claim 2 wherein said shearing surface is hardened.
Claim 5
Dependent Claim
26 words
The first apparatus of claim 2 wherein said means to translate said cutter include a double acting piston connected to said cutter by a pivoting lever.
Claim 6
Dependent Claim
26 words
The first apparatus of claim 2 further including vacuum means proximate said cutting edges, whereby the cut-off stubs of said leads are drawn away after cutting.
Claim 7
Dependent Claim
71 words
The first apparatus of claim 2 further including a second similar apparatus comprising housing, cutter, cover, anvil and translating means, said second apparatus mounted opposedly facing said first apparatus with said cutting edges and row of slots of said first apparatus being parallel to the cutting edges and row of slots of said second apparatus, whereby two parallel rows of aligned leads of said DIP component are simultaneously cut and clinched.
Claim 8
Dependent Claim
23 words
The first apparatus of claim 2 further including means to vertically raise and lower said housing, and means to angularly orient said housing.
