Abstract
A shingle cutter that is portable and can be temporarily attached to and used on the roof with the roofing nails used on the job. The power for cutting results from the housing of the cutting wheel being manually drawn back towards the operator. The shingle cutter has a structural base and two vertical end walls that support a rectangular rack, which holds the cutting block. In one version the rack drives a pinion, which in turn drives the cutting wheel. In a second version, the cutting wheel is free to rotate as it is pulled through the shingle. The cutting block is constrained by rollers in contact with the top and bottom of the rectangular guide bar so that the cutting wheel moves to perform a shearing function with an abutting shear ledge mounted on the structural base.
Claims17
A shingle cutter for cutting roof shingles, comprising:
- a) a U-shaped frame having an elongated, planar base having a top surface, an upright forward wall attached to a first end of the base, and an upright rear wall attached to a second end of the base;
- b) a transverse base attached to the base of the U-shaped frame adjacent the forward wall, the transverse base having a top surface coplanar with the top surface of the base of said U-shaped frame;
- c) a flat, planar, rectangular rack extending between the forward wall and the rear wall and having a substantially constant thickness, the rack being disposed in a plane normal to a plane in which the base is disposed, the rack being disposed above the base of said U-shaped frame by a predetermined distance;
- d) a cutting block movably disposed on said planar rack;
- e) a cutting wheel rotatably mounted on said rack, the cutting wheel having a cutting edge extending between said rack and the base of said U-shaped frame in order to cut a shingle placed on the top surface of the base;
- and
- f) an elongated, planar shear ledge mounted on the base of said U-shaped frame, the ledge having an edge abutting a side of said cutting wheel and a plurality of peg holes defined therein for receiving pegs to hold the shingle at a predetermined angle.
A shingle cutter for cutting roof shingles, comprising:
- a) a U-shaped frame having an elongated, planar base having a top surface, an upright forward wall attached to a first end of the base, and an upright rear wall attached to a second end of the base;
- b) a transverse base attached to the base of the U-shaped frame adjacent the forward wall, the transverse base having a top surface coplanar with the top surface of the base of said U-shaped frame;
- c) a flat, planar, rectangular rack extending between the forward wall and the rear wall and having a substantially constant thickness, the rack being disposed in a plane normal to a plane in which the base is disposed, the rack being disposed above the base of said U-shaped frame by a predetermined distance;
- d) a cutting block movably disposed on said planar rack;
- e) a cutting wheel rotatably mounted on said rack, the cutting wheel having a cutting edge extending between said rack and the base of said U-shaped frame in order to cut a shingle placed on the top surface of the base;
- and
- f) a planar roof anchor storable within said planar base of said U-shaped frame and having a through hole communicating with a slot whereby upon deployment of said roof anchor by sliding said anchor from a stored position within said planar base to a deployed position, said through hole may be fitted over a nail disposed in said roof and said anchor may be moved into a secure position by moving said anchor relative to said nail such that the nail becomes lodged within said communicating slot.
