Abstract
Abstract A handtool for facing off and deburring the rough cut ends of plastic pipe, the cutting tool bit structure being mounted parallel to the work-receiving bore and being adjustable by projecting knobs which are also handles to aid the user in rotating the handtool while pressing the same onto the pipe, the casing of the handtool having a work-receiving bore and a thick block-like portion closing one end of the bore and providing support for the cutting tool bits in the form of small bores extending parallel to the axis of the pipe rather than in the usual transverse or radial disposition.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
175 words
A facing and deburring handtool for use particularly with plastic pipe, comprising: a one-piece casing, slightly elongated and dimensioned to be handheld; said casing having a work-receiving bore in one end of the casing to receive a rough cut end of a pipe; said casing having a block-like portion at the other end of the casing and closing the inner end of said bore; a smaller bore in said block-like portion communicating with said work-receiving bore at the periphery thereof and extending parallel thereto; a cutting tool bit having a cutting edge at the junction of said bores, facing toward the work-receiving bore, and a tool bit shank portion in said smaller bore; said block-like portion having a thickness dimension greater than the length of said cutting tool; and means for securing said tool bit shank portion in said smaller bore for longitudinal adjustment therein, toward and away from said work-receiving bore and longitudinally thereof, for chamfering action on said rough cut end of a pipe when thE handtool is pressed thereon and simultaneously rotated.
Claim 2
Dependent Claim
175 words
A facing and deburring handtool for use particularly with plastic pipe, comprising: a one-piece casing, slightly elongated and dimensioned to be handheld; said casing having a work-receiving bore in one end of the casing to receive a rough cut end of a pipe; said casing having a block-like portion at the other end of the casing and closing the inner end of said bore; a smaller bore in said block-like portion communicating with said work-receiving bore at the periphery thereof and extending parallel thereto; a cutting tool bit having a cutting edge at the junction of said bores, facing toward the work-receiving bore, and a tool bit shank portion in said smaller bore; said block-like portion having a thickness dimension greater than the length of said cutting tool; and means for securing said tool bit shank portion in said smaller bore for longitudinal adjustment therein, toward and away from said work-receiving bore and longitudinally thereof, for chamfering action on said rough cut end of a pipe when thE handtool is pressed thereon and simultaneously rotated.
Claim 3
Dependent Claim
59 words
A facing and deburring handtool according to claim 1 wherein said block-like portion has a slot adjacent to and elongated in the direction of said smaller bore, and said means is a spindle threaded into said tool shank portion and slidable along said slot, with a tightening knob on the spindle to fix the cutting tool in adjusted position.
Claim 4
Dependent Claim
61 words
A facing and deburring handtool according to claim 2 and including a second smaller bore with a second cutting tool operatively mounted therein, said cutting tools between them having cutting edges to face off said rough cut end of a pipe and to bevel both the outer and inner edges, said casing having chip-escaping openings adjacent each of said cutting tools.
Claim 5
Dependent Claim
56 words
A facing and deburring handtool according to claim 3 and wherein said second cutting tool also is also adjustable with a tightening knob, and said tightening knobs are on opposite sides of said casing and project sufficiently from and on opposite sides of said casing as handles to facilitate manual rotation of the casing in use.
