Pipe facing and deburring power head

Claim 2

Apparatus for facing the end of a pipe, comprising: a casing having an opening therein; a rotor received within said casing and having parts thereof in communication with the casing operation, said rotor including means for interconnection with a source of rotative power; hollow sleeve means for receiving the pipe therein, said sleeve means being dimensioned for fitting receipt within the casing opening a limited extend; cutting tool means carried by said rotor on the parts communicating with the casing opening for engaging the end portions of said pipe and finishing the same on rotation of the rotor; said cutting tool means being affixed to an end of shank means received within an opening in said rotor and slidable in a direction toward and away from the pipe end being finished; threaded means interconnecting the shank means and the rotor within said rotor opening for moving said shank means within the rotor opening; a ratchet wheel affixed to said threaded means; a pawl carried by said rotor and arranged to operatively engage said ratchet wheel; and cam means carried by said casing selectively positionable to engage the pawl once each revolution of the rotor for actuating said ratchet means and incrementally advancing said cutting tool means toward the pipe end being finished.

Claim 3

Apparatus for facing the end of a pipe, comprising: a casing having an opening therein; a rotor received within said casing and having parts thereof extending into the casing opening, said rotor including means for interconnection with a source of rotative power; hollow sleeve means for receiving the pipe therein, said sleeve means received within the casing opening a limited extent; cutting tool means mounted on said rotor parts extending into the casing opening for engaging the end portions of said pipe and finishing the same on rotation of the rotor, said cutting tool means being affixed to an end of shank means received within an opening in said rotor and movable in a direction toward and away from the pipe end being finished; rotatable means interconnecting the shank means and the rotor which on rotation moves said shank means and cutting tool means relative to the pipe end; a ratchet wheel affixed to said rotatable means; a pawl carried by said rotor and arranged to operatively engage said ratchet wheel; and cam means carried by said casing selectively positionable to engage the pawl on revolution of the rotor for actuating said ratchet means and advancing said cutting tool means toward the pipe end being finished a predetermined amount each rotor revolution.

Claim 4

Apparatus for facing the end of a pipe, comprising: a casing having an opening therein; a rotor received within said casing and having parts thereof extending into the casing opening, said rotor including means for interconnection with a source of rotative power; hollow sleeve means for receiving the pipe therein, said sleeve means received within the casing opening a limited extent; cutting tool means mounted on said rotor parts extending into the casing opening for engaging the end portions of said pipe and finishing the same on rotation of the rotor, said cutting tool means being affixed to an end of shank means received within an opening in said rotor and movable in a direction toward and away from the pipe end being finished; rotatable means interconnecting the shank means and the rotor which on rotation moves said shank means and cutting tool means relative to the pipe end; a ratchet wheel affixed to said rotatable means; a pawl carried by said rotor and arranged to operatively engage said ratchet wheel; and cam means carried by said casing selectively positionable to engage the pawl on revolution of the rotor for actuating said ratchet means and advancing said cutting tool means toward the pipe end being finished a predetermined amount each rotor revolution.

Claim 5

Apparatus as in claim 1, in which said cam means is selectively adjustable to a position of disengagement with said pawl, and spring means are provided urging said cam means to the disengagement position.

Claim 6

Apparatus as in claim 1, in which said threaded means includes means accessible from outside the rotor for rotating said threaded means.

Claim 7

Apparatus for facing the end of plastic pipe, comprising: casing means adapted to be hand-held having a first cylindrical bore and a second cylindrical bore coaxial with said first bore and of lesser diameter than said first bore; rotor means fittingly received within the casing first bore and having drive shaft means extending through the second bore and outwardly of the casing means for connection to a source of rotative power; hollow cylindrical sleeve means having a continuous bore, a portion of which has a first diameter fittingly receiving the pipe therein and a further portion of a larger diameter, said sleeve means being received into the casing first bore with the rotor means extending into said sleeve means larger diameter bore a predetermined distance; selectively adjustable means carried by said sleeve means for securing the pipe within said sleeve means; facing tool means carried by said rotor engaging the end portions of said pipe on rotation of said rotor for finishing said pipe end portions; means carried by said facing tool means for adjustably moving said facing tool means along said sleeve means; and cam means carried by said casing means selectively positionable to actuate said moving means on each rotation of said rotor means to move said facing tool means a predetermined amount along said sleeve means.

Claim 8

Apparatus for facing the end of plastic pipe, comprising: casing means adapted to be hand-held having a first cylindrical bore and a second cylindrical bore coaxial with said first bore and of lesser diameter than said first bore; rotor means fittingly received within the casing first bore and having drive shaft means extending through the second bore and outwardly of the casing means for connection to a source of rotative power; hollow cylindrical sleeve means having a continuous bore, a portion of which has a first diameter fittingly receiving the pipe therein and a further portion of a larger diameter, said sleeve means being received into the casing first bore with the rotor means extending into said sleeve means larger diameter bore a predetermined distance; selectively adjustable means carried by said sleeve means for securing the pipe within said sleeve means; facing tool means carried by said rotor engaging the end portions of said pipe on rotation of said rotor for finishing said pipe end portions; means carried by said facing tool means for adjustably moving said facing tool means along said sleeve means; and cam means carried by said casing means selectively positionable to actuate said moving means on each rotation of said rotor means to move said facing tool means a predetermined amount along said sleeve means.
