Abstract
Abstract A device for separating a sheet of computer or printout paper from other such papers and carbon papers in a sheet of multiple levels as are commonly employed in computer printouts is designed for table top use with only a short "fall" of discharged paper sheets and a particularly designed folder for insuring proper folding of discharged sheets to thus provide a tabletop separator.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
201 words
A separator for removing the top layer of printout paper from a plurality of layers thereof comprising: a first rotatable drive roller having pressure wheels resiliently urged against said roller and a rotatably mounted breaker roller disposed adjacent thereto, a second rotatable drive roller spaced from said first roller for defining a first folding station therebetween and having pressure wheels resiliently urged against said second roller, a rotatably driven fork structure including at least two adjacent parallel tines disposed intermediate and parallel to said first and second rollers above said first folding station, and at least one folding wedge disposed at a second folding station adjacent and below said second roller on the opposite side thereof from said first roller, said wedge being in the form of a tetrahedron wherein one of the triangular faces of the tetrahedron forms an inclined upper surface for supporting the successive sheets as they are refolded in a stack, said upper surface having a common edge with the base of the tetrahedron substantially parallel to said second drive roller, whereby successive sheets of a separated layer of printout paper are refolded and deposited on said triangular upper surface with fold lines adjacent said common edge.

A separator for removing the top layer of printout paper from a plurality of layers thereof comprising: a first rotatable drive roller having pressure wheels resiliently urged against said roller and a rotatably mounted breaker roller disposed adjacent thereto, a second rotatable drive roller spaced from said first roller for defining a first folding station therebetween and having pressure wheels resiliently urged against said second roller, a rotatably driven fork structure including at least two adjacent parallel tines disposed intermediate and parallel to said first and second rollers above said first folding station, and at least one folding wedge disposed at a second folding station adjacent and below said second roller on the opposite side thereof from said first roller, said wedge being in the form of a tetrahedron wherein one of the triangular faces of the tetrahedron forms an inclined upper surface for supporting the successive sheets as they are refolded in a stack, said upper surface having a common edge with the base of the tetrahedron substantially parallel to said second drive roller, whereby successive sheets of a separated layer of printout paper are refolded and deposited on said triangular upper surface with fold lines adjacent said common edge.
Claim 3
Dependent Claim
51 words
The separator of claim 1 further defined by a variable speed electric motor coupled to said first and second drive roller and to said fork structure for rotating these elements and adjustable speed control means connected to said motor for setting the rate of rotation of said rollers and fork structure.
Claim 4
Dependent Claim
34 words
The separator of claim 2 further defined by a hand wheel connected to a shaft of one of said drive rollers for hand rotation of both of said drive rollers and said fork structure.
Claim 5
Dependent Claim
43 words
The separator of claim 2 further defined by means coupling said variable speed motor to said rollers and fork structure for rotating said second drive roller slightly faster than said first drive roller and said fork structure at an intermediate rate of rotation.
Claim 6
Dependent Claim
32 words
The separator of claim 1 further defined by said folding wedge having a length across the base of said inclined triangular upper surface substantially equal to the length of said drive rollers.
Claim 7
Dependent Claim
19 words
The separator of claim 1 further defined by the upper surface of said wedge having an isosceles triangular configuration.
Claim 8
Dependent Claim
40 words
The separator of claim 1 further defined by a second folding wedge like said first folding wedge disposed at said first folding station with the base of a triangular upper surface thereof adjacent and aligned with said first drive roller.
Claim 9
Dependent Claim
94 words
The separator of claim 1 further defined by said fork structure including a rotatably driven disc having apertures therein, said tines being connected together at a first end thereof with a notched shaft extending axially of the tines at said first end and removably fitting into a depression in a support bracket with a second free end of said tines removably engaging the apertures in said disc whereby said fork structure is adapted to wind carbon paper thereabout and to be removed from the reaminder of the separator for disposal of such carbon paper.
