Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
106 words
Apparatus for supporting substrates that carry electrical components, comprising: a base with a generally flat upper surface for supporting the undersides of said substrates, a plurality of fence portions protruding from said upper surface for bearing against sides of said substrates, a plurality of moveable arms for biasing said substrates against said fence portions, said arms including portions exposed to the underside of said base and adapted for engagement with external actuating means positioned below said base, and spring means for biasing said arms, whereby said arms can be retracted by said external means while said upper surface is fully accessible for insertion of said substrates.
Claim 2
Dependent Claim
106 words
Apparatus for supporting substrates that carry electrical components, comprising: a base with a generally flat upper surface for supporting the undersides of said substrates, a plurality of fence portions protruding from said upper surface for bearing against sides of said substrates, a plurality of moveable arms for biasing said substrates against said fence portions, said arms including portions exposed to the underside of said base and adapted for engagement with external actuating means positioned below said base, and spring means for biasing said arms, whereby said arms can be retracted by said external means while said upper surface is fully accessible for insertion of said substrates.
Claim 3
Dependent Claim
33 words
The apparatus of claim 1 wherein said moveable arms have end portions protruding through slots in said base, said end portions being adapted to engage sides of said substrates to provide said biasing.
Claim 4
Dependent Claim
34 words
The apparatus of claim 2 wherein said moveable arms have lower portions extending generally transversely of said slot and beneath said base, said lower portions being adapted for engaging pins on said external means.
Claim 5
Dependent Claim
28 words
The apparatus of claim 3 wherein said base has grooves on the underside of said base for receiving said pins, said grooves extending generally transversely of said arms.
Claim 6
Dependent Claim
48 words
The apparatus of claim 3 wherein said slots are arcuate and said lower portions of said arms are integral extensions of torsion springs, whereby said arms rotate about the axis of a said torsion spring and said end portions move along a generally arcuate path in said slots.
Claim 7
Dependent Claim
99 words
The apparatus of claim 1 or 5 wherein said fence portions are arranged in pairs such that the two fence portions of each pair are at right angles to each other and wherein there are two said arms associated with each said fence pair, said arms providing a net said biasing force generally toward the center of said pair, whereby said apparatus can accomodate rectangular substrates of various sizes by placing each said substrate with two adjacent sides resting against said two fence portions of each said pair and engaging the two remaining sides with said two biasing arms.
Claim 8
Dependent Claim
37 words
The apparatus of claim 2 wherein end portions are hooked and said fence portions have lip portions for providing a lip over said substrates for providing retention of said substrates on said flat surface of said base.
Claim 9
Dependent Claim
34 words
The apparatus of claim 7 wherein said lip portions are tacks fastened to the top surfaces of said fence portions, said tacks having heads extending outward from said fence portions to provide said lip.
Claim 10
Dependent Claim
23 words
The apparatus of claim 1 or 7 further comprising grooves adjacent to said fences on the side on which said substrates are retained.
Claim 11
Dependent Claim
72 words
An adaptor for mounting the apparatus of claim 1 on a moving table, comprising: a wedge portion including a frusto-conical surface for mating with a frusto-conical surface on a first attachment pin extending downwardly from the underside of the base of said apparatus and locking means spaced from said wedge portion for cooperating with a second pin extending downwardly from the underside of said base to press together both said frusto-conical surfaces.
Claim 12
Dependent Claim
65 words
The adaptor of claim 10 wherein said wedge portion is V-shaped in a cross section taken along a plane perpendicular to the axis of said frusto-conical portion. and said frusto-conical portion is positioned at the center of said V-shape, whereby during mounting of said apparatus to said adaptor said first insertion pin is directed toward said frusto-conical surface of said wedge portion by said V-shape.
Claim 13
Dependent Claim
81 words
The adaptor of claim 11 wherein said locking means includes a groove extending transversely of the line connecting the centers of said locking means and said wedge portion, said groove being adapted to receive said second attachment pin, and wherein said groove includes a protuberance extending radially-inward from the wall of said groove furthest from said wedge portion, said protuberance being adapted to force said second attachment pin inward and through it force said first pin tightly against said wedge portion.
Claim 14
Dependent Claim
88 words
Apparatus for actuating the substrate retaining arms of the support apparatus of claim 1, comprising: a flat panel for supporting the underside of the base of said support apparatus, a plurality of pins extending upward from said panel for engaging exposed portions of said retaining arms, means for retaining said support apparatus on said panel, and means for sliding said support apparatus relative to said panel to cause said pins to move said arms, whereby said arms can be retracted to allow insertion or removal of said substrates.
Claim 15
Dependent Claim
26 words
The apparatus of claim 13 wherein said means for sliding includes a first member with a V-shaped surface for engaging one corner of said support apparatus.
Claim 16
Dependent Claim
17 words
The apparatus of claim 14 wherein said first member includes a lip for retaining said support apparatus.
Claim 17
Dependent Claim
61 words
The apparatus of claim 14 wherein said means for sliding further includes an over-center mechanism and an operating handle, said mechanism being connected to said first member to slide it across said plate, a second member spaced from said first member for retaining another side of said support apparatus, and spring means for biasing said second member toward said first member.
