Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
146 words
Apparatus for supporting glass-plastic assemblies for lamination in an autoclave comprising a rack for supporting a plurality of said assemblies in an upright position, said rack comprising support means extending horizontally for supporting each of said glass-plastic assemblies along a longitudinal side edge, said support means being provided with longitudinally spaced vertically extending bottom edge spacing means separated from one another along said support means by a distance approximating, but slightly more than the thickness of said assemblies to be supported, means for separting adjacent of said assemblies by engaging the upper edge of at least one of each pair of adjacent of said assemblies, flexible interconnecting means for interconnecting said upper edge separating and engaging means to one another, and means adapted to be coupled to said flexible interconnecting means in such a manner to impart rigidity to said flexible interconnecting means when coupled thereto.
Claim 2
Dependent Claim
146 words
Apparatus for supporting glass-plastic assemblies for lamination in an autoclave comprising a rack for supporting a plurality of said assemblies in an upright position, said rack comprising support means extending horizontally for supporting each of said glass-plastic assemblies along a longitudinal side edge, said support means being provided with longitudinally spaced vertically extending bottom edge spacing means separated from one another along said support means by a distance approximating, but slightly more than the thickness of said assemblies to be supported, means for separting adjacent of said assemblies by engaging the upper edge of at least one of each pair of adjacent of said assemblies, flexible interconnecting means for interconnecting said upper edge separating and engaging means to one another, and means adapted to be coupled to said flexible interconnecting means in such a manner to impart rigidity to said flexible interconnecting means when coupled thereto.
Claim 3
Dependent Claim
75 words
Apparatus as in claim 1, wherein said means to impart rigidity comprises tensioning means adapted to be securEd to one end of said flexible interconnecting means whereby said means for engaging the upper edges of said assemblies are supported in spaced relation between the top edges of adjacent of said assemblies within said rack to support said assemblies in upright position with the bottom edges of said assembly resting on said horizontally extending support beams.
Claim 4
Dependent Claim
14 words
Apparatus as in claim 1, wherein said means to impart rigidity comprises locking means.
Claim 5
Dependent Claim
67 words
Apparatus as in claim 1, wherein said horizontally extending support means comprises a pair of parallel beams having their upper surfaces in a common horizontal plane and said bottom edge spacing means comprises a plurality of vertically extending spacing members longitudinally spaced along the length of each of said beams, a spacing member for each beam being aligned with a corresponding spacing member for the other beam.
Claim 6
Dependent Claim
47 words
Apparatus as in claim 4, wherein each spacing member along the length of each of said beams has a different color from that of each spacing member adjacent thereto and the same color as said corresponding spacing member for the other beam of said pair of beams.
Claim 7
Dependent Claim
118 words
Apparatus as in claim 1, wherein said flexible interconnecting means comprises a chain and said upper edge separating and engaging means comprises a base portion attached to alternate links of said chain and a stem member extending from said base portion in a direction away from said chain, each said base portion having a thickness in the direction of the length of said chain sufficient for adjacent base portions to abut when said chain is straight and each said stem member being sufficiently thinner than said base portion in the direction of the length of said chain to provide a space between adjacent stem members sufficient to receive the upper edge portion of one of said assemblies therebetween.
Claim 8
Dependent Claim
36 words
Apparatus as in claim 6, wherein said base portions are apertured in a direction parallel to the length of said chain to provide aligned apertures adapted to receive a locking pin when said chain is straight.
