Abstract An apparatus is provided for use in optimally arranging covering units, such as tiles or the like, or for enabling the precutting of such covering units before such units are applied to the floor or wall or ceiling to be covered. A first prescaled grid is provided on a substantially opaque sheet of paper on which the dimensions of the surface to be covered may be laid out. The exact dimensions of the floor, wall or ceiling to be covered may be laid out to scale on the first substantially opaque sheet. A second grid or line arrangement corresponding to the dimensions of the covering unit is provided on a substantially transparent sheet. This second grid is scaled to correspond to the scaling of the first grid on the substantially opaque sheet. By laying the second grid on the transparent sheet over the first grid, and varying its position, the optimal arrangement of the covering unit may be selected to provide the optimal arrangement of the covering units both for aesthetic purposes and to enable minimum cutting of the covering units. Further, the exact dimensions of each covering unit to be cut may be determined and the covering units may be precut accordingly. The transparent sheet may be further provided with openings at the intersection of the grid lines to enable the marking of the location of such intersections on the substantially opaque sheet.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
146 words
Apparatus for use in optimally arranging covering units, such as tiles or the like, or for precutting such covering units, comprising: a first grid arranged on a substantially opaque sheet on which the dimensions of a surface to be covered, such as a floor, wall or ceiling, may be scribed or laid out to a predetermined scale; and a second grid or arrangement arranged on a substantially transparent sheet, said second grid being scaled to correspond to the scaling of said first grid and said second grid or arrangement corresponding to the dimensions and selected arrangement of said covering units to be applied to said surface whereby said second grid corresponding to said covering units may be selectably and optimally positioned over said first grid having thereon the layout of the surface to be covered and the necessary cutting of said covering units may be observed.
Claim 2
Dependent Claim

Apparatus for use in optimally arranging covering units, such as tiles or the like, or for precutting such covering units, comprising: a first grid arranged on a substantially opaque sheet on which the dimensions of a surface to be covered, such as a floor, wall or ceiling, may be scribed or laid out to a predetermined scale; and a second grid or arrangement arranged on a substantially transparent sheet, said second grid being scaled to correspond to the scaling of said first grid and said second grid or arrangement corresponding to the dimensions and selected arrangement of said covering units to be applied to said surface whereby said second grid corresponding to said covering units may be selectably and optimally positioned over said first grid having thereon the layout of the surface to be covered and the necessary cutting of said covering units may be observed.
Claim 3
Dependent Claim
41 words
An apparatus in accordance with claim 1 wherein said transparent sheet is provided with openings at the intersection of the lines of said second grid thereon to enable the marking of the location of such intersections on said substantially opaque sheet.
Claim 4
Dependent Claim
32 words
An apparatus in accordance with claim 1 wherein said transparent sheet is provided with markings representing standard United States measure along one edge and markings representing metric measure along an opposite edge.
