Abstract
A new PIPE BEVELER for ATTACHING TO A ROTARY SAW FOR PRODUCING THIRTY DEGREE BEVELS ON PIPES. The inventive device includes a coupling plate adapted for coupling with respect to a rotary saw. A receiving collar having a generally frustoconical configuration is integral with the coupling plate. An abrasive material is disposed around an internal periphery of the receiving collar for grinding pipes into a bevel of thirty degrees.
Claims11
A pipe beveler for attaching to a rotary saw for producing thirty degree bevels on an outside edge of a pipe comprising, in combination:
- a coupling plate adapted for coupling with respect to a rotary saw, the coupling plate having a generally circular configuration with planar inner and outer surfaces, the coupling plate having a mounting aperture directed therethrough, the mounting aperture dimensioned for receiving an arbor of the rotary saw, the mounting aperture including a coupling washer disposed therein, the coupling plate having a peripheral flange extending outwardly therefrom;
- a receiving collar having a generally frustoconical configuration, the receiving collar having a smaller open inner end and a larger open outer end, the smaller open inner end being integral with the peripheral flange of the coupling plate, the receiving collar angling outwardly thirty degrees from the smaller open inner end to the larger open outer end, the receiving collar having a width greater than twice a width of the peripheral flange, the larger open outer end having a diameter about twice as great as a diameter of the smaller open inner end, the receiving collar having an abutting flange disposed around an interior surface thereof positioned outwardly of the smaller open inner end;
- and
- an abrasive material disposed around an internal periphery of the receiving collar, the abrasive material disposed on the inner surface of the receiving collar disposed between the larger open outer end and the abutting flange.

A pipe beveler comprising:
- a coupling plate adapted for coupling with respect to a rotary saw;
- a receiving collar having a generally frustoconical configuration being integral with the coupling plate;
- the receiving collar having a smaller open inner end and a larger open outer end, the smaller open inner end being positioned towards the coupling plate:
- an abrasive material disposed around an internal periphery of the receiving collar;
- the receiving collar having an abutting flange disposed around an interior surface thereof positioned towards the smaller open inner end and being for abutting a pipe being beveled for holding the pipe at a constant angle with respect to the receiving collar;
- an outer edge of the abutting flange tapering together away from a point of contact with the interior surface of the receiving collar;
- and
- the abrasive material being disposed on the inner surface of the receiving collar abutting the outer edge of the abutting flange and extending towards the larger open outer end, the tapered outer end of the abutting flange being angled such that it helps prevent sliding of the abrasive material towards the smaller open end of the receiving collar.
