Claim 1
Independent Claim
267 words
A leveling attachment for power tools having a body and a material cutting tool projecting from the body comprising a unitary member of relatively rigid material having an inverted V-shaped portion with two downwardly and outwardly extending legs having inclined surfaces on the underside thereof and a bifurcated support extending upwardly from said V-shaped portion, said support having a pair of spaced parallel legs aligned with the legs of said V-shaped portion and aligned openings extending through said legs, a bolt extending through said openings and having a cooperating nut, a flexible strap having perforated end portions with one end portion engaging one end of said bolt and lying against the outer surface of one of said legs of said bifurcated support and the adjoining leg of said V-shaped portion and the other end engaging the other end of said bolt and lying against the outer surface of the other of said legs of said bifurcated support and the adjoining leg of said V-shaped portion, means on said strap for adjusting the length thereof, said strap being adapted to encircle the body of said power tool with said inclined surfaces engaging said body and said adjusting means functioning to secure said strap and said unitary member to said body, and adjustable leveling means including a support extending therefrom, said support having an opening therein and positioned between the legs of said bifurcated support and in engagement with said bolt whereby said level is angularly movable relative to said power tool to facilitate positioning of the material cutting tool at desired angles relative to said material being cut.
