Abstract:
1. A device for removing shingles and nails from a roof deck having a base and a crest, comprising: saw means for cutting the shingles, the saw means for cutting the shingles situated in a substantially vertical orientation and aligned in a cutting plane; means for operating the saw means for cutting the shingles; a wedge having a plurality of teeth with an outermost tooth on each side defining a width of the wedge between them, the teeth having a top surface, a bottom surface, a leading edge, and a trailing edge, each tooth separated from an adjacent tooth by a channel, the channel defining an opening between the leading edge of adjacent teeth and a closed notch at the trailing edge of adjacent teeth; each channel formed between the adjacent teeth in the wedge extending equi-distant between the adjacent teeth from the opening in the leading edge to the closed notch in the trailing edge, the top surface of the plurality of teeth in the wedge upwardly tapering from the leading edge to the trailing edge; a plate having a front, a back, a top side, a bottom side, a left side and a right side and defining a width between the left side and the right side, the width of the plate being substantially the same as the saw means for cutting the shingles, the plate situated in a substantially vertical orientation with the front and the back of the plate aligned in the cutting plane directly behind the saw means for cutting the shingles, the top side of the plate positioned directly behind the saw means for cutting the shingles, and a completely open space defined adjacent to the saw means for cutting the shingles and to the left side and right side of the plate; a horizontal arm having a proximal end attached to the plate and extending outwardly a length from the plate to a distal end, the horizontal arm substantially rigid along the length between the proximal end and the distal end; means for adjusting the height of the distal end of the horizontal arm in relation to the roof deck to adjust the position of the leading edge of the teeth of the wedge in relation to the roof deck; first mechanical pulling means for pulling the device from the base of the roof deck to the crest of the roof deck; the saw means for cutting the shingles mounted directly above and substantially perpendicular to the wedge, the width of the wedge larger than the saw means for cutting shingles with one or more of the plurality of teeth positioned on either side of the saw means for cutting shingles wherein the plurality of teeth of the wedge lifting the shingles from the roof deck and the combination of the plurality of teeth and the channels removing the nails from the roof deck wherein as the nail enters the channel at the leading edge, a portion of the nail engages the opposed teeth, as the nail slides through the channel toward the trailing edge, the portion of the nail engaging the opposed teeth is gradually lifted upwardly by the upwardly tapering teeth thereby completely removing the nail from the roof deck when the nail reaches the closed notch of the wedge; the saw means for cutting the shingles cutting the shingles into a left section and a right section directly above the wedge as the device is pulled up the roof deck in a strip run, the left section and right section of the shingles passing the saw means for cutting the shingles with the left side of the plate continuously directing the left section of shingles to the left side of the plate and the right side of the plate continuously directing the right section of shingles to the right side of the plate with a portion of the shingles in each of the left section of shingles and the right section of shingles passing over the wedge and through the completely open space and adjacent to the plate during the strip run.
