ABSTRACT:
A carpet cutter for concurrently cutting a pair of overlapping carpet portions lying on a floor, comprising a body, flat longitudinally extending base plate extending downward from the body and adapted to be drawn across the floor, and a handle extending upwardly from the plate for drawing the plate across the floor. Upper, lower and intermediate, elongated guides are spaced vertically below the handle and above the undersurface of the base plate forming a pair of vertically spaced, one-above-the-other, parallel, upper and lower, horizontally extending, longitudinal slots between the guides. A pair of overlapping carpet portions are respectively positioned in the slots. The carpet portions have a sliding engagement with the guides for maintaining alignment of the overlapped carpet portions suitable for making simultaneous, parallel, one-above-the-other, abutting cuts with the same stroke to concurrently sever the carpet backings of the overlapping carpet portions, so that the severed edges can be joined to provide an invisible seam. A blade attached to the body of the cutter in a configuration adjacent the guides has its cutting edge intersecting with each horizontally extending, longitudinal slot for severing the carpet backings, as the base plate is drawn across the floor. A pair of oppositely diverging blades (FIG. 1) can be included for either right hand or left hand usage, and the tool can be powered with a driven circular cutting blade (FIGS. 5-7).
