Abstract
Abstract A powered means for simultaneously cutting two seal portions of conventional windshield tracks. An L-shaped blade having both legs with sharpened edges is attached to an elongated frame member having a grasping portion thereof. A force transferring means is adapted to be operatively connected to the elongated frame member and to a powered force supplying means, such as an air hammer or the like. A collar on the frame member prevents movement of the force transferring means towards the blade during operation.

Total Claims: 9
Claim 1
Independent Claim
193 words
An assembly for cutting windshield tracks and the like comprising a. cutting means for simultaneously cutting two portions of a windshield track or the like, said cutting means comprising a generally L-shaped cutting blade having first and second legs of said L sharpened, said legs for cutting different portions of a windshield track simultaneously, b. means for mounting said cutting means and for providing positive direction therefor, said means including an elongated frame member having a portion thereof for grasping by an operator and an end portion for mounting the first of the legs of said L-shaped blade, c. power means for supplying a mechanical force to said frame member in a direction substantially perpendicular to the direction of elongation thereof, and d. means for transferring a mechanical force from said power means to said cutting means through said frame member, said transferring means comprising (i) means for abutting said elongated frame member at a point thereof between the portion thereof for grasping by an operator and the general area of mounting of said cutting means to said frame member, and (ii) means for operatively connecting said force transferring to said power means.
Claim 2
Dependent Claim
193 words
An assembly for cutting windshield tracks and the like comprising a. cutting means for simultaneously cutting two portions of a windshield track or the like, said cutting means comprising a generally L-shaped cutting blade having first and second legs of said L sharpened, said legs for cutting different portions of a windshield track simultaneously, b. means for mounting said cutting means and for providing positive direction therefor, said means including an elongated frame member having a portion thereof for grasping by an operator and an end portion for mounting the first of the legs of said L-shaped blade, c. power means for supplying a mechanical force to said frame member in a direction substantially perpendicular to the direction of elongation thereof, and d. means for transferring a mechanical force from said power means to said cutting means through said frame member, said transferring means comprising (i) means for abutting said elongated frame member at a point thereof between the portion thereof for grasping by an operator and the general area of mounting of said cutting means to said frame member, and (ii) means for operatively connecting said force transferring to said power means.
Claim 3
Dependent Claim
44 words
