Abstract
Abstract A device is provided for clamping the side edges of a receiver to hold it in place while a flexible electrode or a flexible photoconductor is stripped therefrom after charging so that the electrostatic attraction between the member being stripped away and the receiver sheet will not disturb the position of the receiver sheet. The clamps pivot against the receiver tending to stretch it laterally on the platen to hold it tight thereagainst.

Claim 1
Independent Claim
151 words
An apparatus for clamping lateral edges of a length of material, said apparatus comprising: a platen, having side edges, for supporting said length of material fed from a first end of said platen toward a second end thereof; respective clamping means adjacent each side edge of said platen, each clamping means being movable from a first position spaced from said side edges to a second position in engagement with said platen to clamp the lateral edges of said length of material to said platen; actuatable means coupled to each of said clamping means for moving said clamping means from said first position to said second position; and respective guide means along each side edge of said platen for guiding said length of material, each said guide means having means defining at least one opening through which each of said clamping means is movable from said first position to said second position.
Claim 2
Independent Claim
151 words
An apparatus for clamping lateral edges of a length of material, said apparatus comprising: a platen, having side edges, for supporting said length of material fed from a first end of said platen toward a second end thereof; respective clamping means adjacent each side edge of said platen, each clamping means being movable from a first position spaced from said side edges to a second position in engagement with said platen to clamp the lateral edges of said length of material to said platen; actuatable means coupled to each of said clamping means for moving said clamping means from said first position to said second position; and respective guide means along each side edge of said platen for guiding said length of material, each said guide means having means defining at least one opening through which each of said clamping means is movable from said first position to said second position.
Claim 3
Independent Claim
151 words
An apparatus for clamping lateral edges of a cut sheet comprising: a platen, having side edges, for supporting said cut sheet fed from a first end of said platen toward a second end thereof; a guide along each side edge of said platen for guiding said sheet, each guide having means defining a plurality of slots; a plurality of clamping arms mounted adjacent each side edge of said platen for pivotal movement from a first position spaced from said side edges to a second position in engagement with said platen a foot on each of said clamping arms, each movable through one of said slots upon movement of said arms from said first position to said second position to clamp the lateral edges of said sheet against said platen; and actuatable moving mean coupled to said clamping arms for moving said clamping arms from said first position to said second position
Claim 4
Independent Claim
151 words
An apparatus for clamping lateral edges of a cut sheet comprising: a platen, having side edges, for supporting said cut sheet fed from a first end of said platen toward a second end thereof; a guide along each side edge of said platen for guiding said sheet, each guide having means defining a plurality of slots; a plurality of clamping arms mounted adjacent each side edge of said platen for pivotal movement from a first position spaced from said side edges to a second position in engagement with said platen a foot on each of said clamping arms, each movable through one of said slots upon movement of said arms from said first position to said second position to clamp the lateral edges of said sheet against said platen; and actuatable moving mean coupled to said clamping arms for moving said clamping arms from said first position to said second position
Claim 5
Dependent Claim
206 words
In an electrophotographic device, a receiver sheet clamping apparatus comprising: a platen, having side edges, for supporting a receiver sheet having lateral edges, fed from a first end of said platen toward a second end thereof; a guide along each side edge of said platen for guiding said receiver sheet, each guide having means defining a plurality of slots; a support means along each side edge of said platen; a plurality of clamping arms having feet thereon, said clamping arms being pivotally mounted on each of said support means for movement from a first position wherein said feet are spaced from said platen to a second position wherein said feet move through said slots into engagement with said platen to grip said lateral edges of said receiver sheet therebetween; a pressure link extending along each of said support means engageable with said arms; a pair of spaced pivot arms respectively pivotally interconnecting each of said pressure links with said respective support means; linkage means connected to at least one of said pivot arms; and actuatable moving means connected to said linkage means for moving said pressure links into engagement with said clamping arms to moved said clamping arms from said first position to said second position.
Claim 6
Dependent Claim
206 words
In an electrophotographic device, a receiver sheet clamping apparatus comprising: a platen, having side edges, for supporting a receiver sheet having lateral edges, fed from a first end of said platen toward a second end thereof; a guide along each side edge of said platen for guiding said receiver sheet, each guide having means defining a plurality of slots; a support means along each side edge of said platen; a plurality of clamping arms having feet thereon, said clamping arms being pivotally mounted on each of said support means for movement from a first position wherein said feet are spaced from said platen to a second position wherein said feet move through said slots into engagement with said platen to grip said lateral edges of said receiver sheet therebetween; a pressure link extending along each of said support means engageable with said arms; a pair of spaced pivot arms respectively pivotally interconnecting each of said pressure links with said respective support means; linkage means connected to at least one of said pivot arms; and actuatable moving means connected to said linkage means for moving said pressure links into engagement with said clamping arms to moved said clamping arms from said first position to said second position.
Claim 7
Dependent Claim
100 words
In an electrophotographic device, as claimed in claim 3, said support means comprising: generally U-shaped members having a long leg and a short leg interconnected by a base, said base being attached to said platen with said short leg closest to said side edges of said platen; means defining opposed slots in said long and short legs through which said arms extend, said slots in said short legs serving as pivots for said arms and said Slots in said long legs being of sufficient size to facilitate pivotal movement of said arms from said first position to said second position.
Claim 8
Dependent Claim
26 words
In an electrophotographic device, as claimed in claim 4, further comprising: spring means connected to each of said arms urging said arms toward said first position.
Claim 9
Dependent Claim
109 words
In an electrophotographic device, as claimed in claim 3, wherein said linkage means includes: a rotatable rod extending transversely of said platen; a pair of spaced yokes each having a first end fixedly connected to said rod and each having a second end pivotally connected to one of each of said pair of pivot arms; and a lever having a first and second end, said first end being fixedly connected to said rod; and wherein said moving means includes: a solenoid connected to said second end of said lever for rotating said rod upon actuation of said solenoid to move said pressure links into engagement with said clamping arms.
