Abstract
Abstract A plotting system (10) including a plotting device (40) for plotting on paper (52) is provided. The plotting system (10) includes a work surface (28). A supply source (50) of paper (52) to be plotted is disposed adjacent the work surface (28). A take-up roll (56) is disposed adjacent the work surface (28) opposite the supply source (50). A supply source (64) of carbon paper (66) is disposed adjacent to the work surface (28). A take-up roll (72) is disposed adjacent the work surface (28) opposite the supply source (64). Structure (60) is interconnected to the first take-up roll (56) for periodically advancing the paper (52) across the work surface (28) from the supply source (50) to the take-up roll (56). Structure is interconnected to the second take-up roll (72) for continuously advancing the carbon paper (66) across the work surface (28) from the supply source ( 64) to the second take-up roll (72) while the plotting device (40) plots on the paper (52).

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
137 words
A plotting system including a plotting device for plotting on paper comprising: a work surface having opposed ends and sides; a supply source of paper to be plotted disposed adjacent said work surface; first take-up means disposed adjacent said work surface opposite said supply source of paper; a supply source of carbon paper disposed adjacent said work surface; second take-up means disposed adjacent said work surface opposite said supply source of carbon paper; means interconnected to said first take-up means for periodically advancing the paper across said work surface from said supply source of paper to said first take-up means; and means interconnected to said second take-up means for continuously advancing the carbon paper across said work surface from said carbon paper supply source to said second take-up means while the plotting device plots on the paper.
Claim 2
Dependent Claim
137 words
A plotting system including a plotting device for plotting on paper comprising: a work surface having opposed ends and sides; a supply source of paper to be plotted disposed adjacent said work surface; first take-up means disposed adjacent said work surface opposite said supply source of paper; a supply source of carbon paper disposed adjacent said work surface; second take-up means disposed adjacent said work surface opposite said supply source of carbon paper; means interconnected to said first take-up means for periodically advancing the paper across said work surface from said supply source of paper to said first take-up means; and means interconnected to said second take-up means for continuously advancing the carbon paper across said work surface from said carbon paper supply source to said second take-up means while the plotting device plots on the paper.
Claim 3
Dependent Claim
45 words
The plotting system of claim 1 wherein said supply source of paper and said first take-up means are disposed adjacent said work surface opposed sides and said supply source of carbon paper and said second take-up means are disposed adjacent said work surface opposed ends.
Claim 4
Dependent Claim
125 words
A plotting system having a plotting device in which a continuous web of paper to be plotted is spread on a supporting surface of a table, wherein the paper traverses the table from a supply location to a take-up location and wherein a continuous web of carbon paper is spread on the supporting surface of the table, wherein the carbon paper traverses the table from a supply location to a take-up location, comprising: first means for periodically advancing the paper across the surface of the table from the supply location to the take-up location; and second means for continuously advancing the carbon paper across the surface of the table from the supply location to the take-up location while the plotting device plots on the paper.
Claim 5
Dependent Claim
125 words
A plotting system having a plotting device in which a continuous web of paper to be plotted is spread on a supporting surface of a table, wherein the paper traverses the table from a supply location to a take-up location and wherein a continuous web of carbon paper is spread on the supporting surface of the table, wherein the carbon paper traverses the table from a supply location to a take-up location, comprising: first means for periodically advancing the paper across the surface of the table from the supply location to the take-up location; and second means for continuously advancing the carbon paper across the surface of the table from the supply location to the take-up location while the plotting device plots on the paper.
Claim 6
Dependent Claim
46 words
The plotting system of claim 3 wherein: said first means advances the paper across the surface of the table in a first direction and said second means advances the carbon paper across the surface of the table in a second direction perpendicular to said first direction.
Claim 7
Independent Claim
109 words
A system for plotting information on paper supported on a work surface and including a plotting device movable over the work surface and wherein carbon paper is utilized for generating a hectographic stencil comprising: means for periodically advancing the paper across the work surface; and means for continuously advancing the carbon paper across the work surface as the plotting device moves over the work surface to thereby plot the information on the paper and generate the hectographic stencil, such that forces generated between the paper and the carbon paper as the paper is plotted are minimized to enable the plotted paper to be periodically advanced across the work surface.
Claim 8
Independent Claim
109 words
A system for plotting information on paper supported on a work surface and including a plotting device movable over the work surface and wherein carbon paper is utilized for generating a hectographic stencil comprising: means for periodically advancing the paper across the work surface; and means for continuously advancing the carbon paper across the work surface as the plotting device moves over the work surface to thereby plot the information on the paper and generate the hectographic stencil, such that forces generated between the paper and the carbon paper as the paper is plotted are minimized to enable the plotted paper to be periodically advanced across the work surface.
Claim 9
Dependent Claim
89 words
A plotting system for plotting a hectographic stencil on paper supported on a work surface and including a plotting device movable over the work surface wherein hectographic carbon paper is disposed between the paper and the work surface comprising: means for periodically advancing the paper across the work surface; and means for continuously advancing the hectographic carbon paper across the work surface as the plotting device moves over the work surface to thereby minimize forces generated between the hectographic carbon paper and the paper as the paper is plotted.
Claim 10
Dependent Claim
89 words
A plotting system for plotting a hectographic stencil on paper supported on a work surface and including a plotting device movable over the work surface wherein hectographic carbon paper is disposed between the paper and the work surface comprising: means for periodically advancing the paper across the work surface; and means for continuously advancing the hectographic carbon paper across the work surface as the plotting device moves over the work surface to thereby minimize forces generated between the hectographic carbon paper and the paper as the paper is plotted.
Claim 11
Independent Claim
38 words
