The blade mounting plate is secured to the front end of the handle and the rod mounting sleeve is secured to the bottom of the two previous components. A blade cover plate secures a razor blade between itself and the blade mounting plate with the bottom edge of the razor blade captured in a groove that extends along the top surface of the carpet lifting rod. The carpet lifting rod is longitudinally adjustable within the rod mounting sleeve. In operation, the pointed front end of the carpet lifting rod is driven along the top surface of the concrete below the bottom surface of the carpet thereby lifting it up to a position where it is cut by the razor blade as the device is continuously pushed along beneath the carpet. ## Claims ### Claim 1 A device for lifting and cutting glued-down carpet comprising: an elongated handle having a predetermined length L1, said handle having a longitudinally extending main body portion having a top end and a bottom end; primary mounting means are secured to said handle adjacent its bottom end for holding a blade and it has a blade mounting plate having a front end, a rear end, a top edge, a bottom edge and a side wall; it also has a blade cover plate and means for detachably securing it to said blade mounting plate with said blade sandwiched therebetween; secondary mounting means are secured to said handle adjacent its bottom end for holding a carpet lifting rod; an elongated carpet lifting rod having a longitudinally extending axis, said carpet lifting rod having a shank portion and pointed front end portion, said carpet lifting rod is secured to said secondary mounting means; and a blade having a front cutting edge, a bottom edge and a rear edge, said blade being secured to said primary mounting means with its cutting edge oriented forwardly. ### Claim 2 (depends on 1) A device for lifting and cutting glued-down carpet as recited in claim 1 wherein L1 is between 4 and 7 feet in length. ### Claim 3 (depends on 1) A device for lifting and cutting glued-down carpet as recited in claim 1 wherein said handle has a bottom leg portion having a longitudinal axis that intersects the longitudinal axis of said main body portion at an obtuse angle A. ### Claim 4 (depends on 1) A device for lifting and cutting glued-down carpet as recited in claim 1 further comprising means for adjusting an angle that the longitudinal axis of the main body portion of said handle makes with said primary mounting means. ### Claim 5 (depends on 1) A device for lifting and cutting glued-down carpet as recited in claim 1 further comprising means for aligning the front cutting edge of said blade. ### Claim 6 A device for lifting and cutting glued-down carpet comprising: an elongated handle having a predetermined length L1, said handle having a longitudinally extending main body portion having a top end and a bottom end; primary mounting means are secured to said handle adjacent its bottom end for holding a blade; secondary mounting means are secured to said handle adjacent its bottom end for holding a carpet lifting rod; an elongated carpet lifting rod having a longitudinally extending axis, said carpet lifting rod having a shank portion and a pointed front end portion, said carpet lifting rod secured to said secondary mounting means; said secondary mounting means having a rod mounting sleeve having a longitudinally extending axis and the shank portion of said rod being longitudinally adjustable in said rod mounting sleeve; and a blade having a front cutting edge, a bottom edge and a rear edge, said blade being secured to said primary mounting means with its cutting edge oriented forwardly. ### Claim 7 (depends on 6) A device for lifting and cutting glued-down carpet as recited in claim 6 wherein the shank portion of said carpet lifting rod has a top surface having a longitudinally extending groove that removably receives the bottom edge of said blade.
