"The invention consists in constructing a compass-saw of a blade tapered from the center toward each end, curved transversely with a curve gradually decreasing in size from the center toward each end, and pivoted at its center by a clamping-screw to a handle groove upon its opposite edges, so that larger and smaller curves can be sawed by the same saw, and a curved kerf can be continued in a curve in the opposite direction..."

An example is reported by Lee Richmond of The Best Things, in Herndon, VA. The saw is marked "Pat. Jan. 10, 1882" on both blade and handle. The two blades are for cutting in opposite directions. The handle appears to be apple.
