Abstract:     A triple lap siding product is machined from a strip of wide lap hardboard siding to give the appearance of three narrow laps of natural wood siding or actual drop siding cut from 3/4'' lumber. The configuration for simulating narrow lap siding is machined with beveled profiles having opposed first and second surfaces. Each strip of siding includes a plurality of inclined cuts and vertical cuts subdividing the single strip into three lap portions. The configuration for simulating actual drop siding includes a plurality of arcuate cuts and vertical cuts that subdivide each strip of siding into three lap portions. For both types of siding, the leading edge of one strip is adapted to cooperate with the trailing edge of another strip to form a continuous lap siding installation on the building or the like.

First Claim:

What is claimed is:     1. A triple lap hardboard siding formed from a single, elongated strip of hardboard material of a thickness of approximately 7/16 of an inch and a width of approximately 12 inches, said siding having front and back opposed surfaces, a leading edge and a trailing edge, respectively disposed at opposite ends of the width of the strip, said siding including a first flat surface extending parallel to the back surface from the trailing edge of the siding and terminating at a point intermediate the width of the strip; a first arcuate cut portion extending from the terminating point of said first flat portion and penetrating the strip to a point intermediate the thickness thereof; a first vertical cut portion extending perpendicular to said back surface from the terminating point of said first arcuate cut and terminating at the front surface of the strip to form a first vertical wall member; a second flat portion extending parallel to the back surface from said first vertical wall member and terminating at a point intermediate the width of the strip, the width of said second flat portion being substantially equal to that of said first flat portion; a second arcuate cut portion extending from the terminating point of said second flat portion and penetrating the strip to a point intermediate the thickness thereof; a second vertical cut portion extending perpendicular to said back surface from the termination of said second arcuate cut and terminating at the front surface of the strip to form a second vertical portion; a third flat portion extending parallel to said back surface from said second vertical wall member and terminating at a point intermediate the width of the strip, said third flat portion having substantially the same width as said second and first flat portions; a third arcuate cut extending from the termination of said third flat portion and penetrating the strip to a point intermediate the thickness thereof; a flat cut portion extending from the termination of said third arcuate cut to the leading edge of said strip, said flat cut portion being parallel to said back surface and being of a length of at least 3/4 inch; said first, second and third arcuate cuts each having a radius of approximately 2" to 23/8", such that the third arcuate cut fairs into the flat cut portion, said first, second and third arcuate cuts each penetrating said strip at approximately the same thickness level; said back surface of the strip including a substantially rectangular cut portion at the trailing edge of the strip, the thickness of said rectangular cut portion being substantially the same as the thickness of the strip between said back surface and said flat cut portion at the leading edge thereof, and with the width of said rectangular cut portion being substantially the same as the width of said flat cut portion which extends from the termination of said third arcuate cut to the leading edge of said strip, such that the leading edge of one strip of hardboard siding cooperates with the trailing edge of another strip of hardboard siding to form a continuous siding installation.
