Abstract
Abstract Apparatus for internally peeling metal tubes includes a peeling head rotatable about a longitudinal axis. An elongated cutter holder having opposite end portions is mounted on the head and extends generally parallel to the longitudinal axis of the head. One end portion of the cutter holder is mounted to the head by a pivot connection for providing swinging movement of the holder toward and away from the longitudinal axis of the head. Both of the end portions of the cutter holder are also adjustable outwardly and inwardly relative to the longitudinal axis of the head.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
88 words
Apparatus for internally peeling tubes comprising: a peeling head having a longitudinal axis about which said head is rotatable, an elongated cutter holder extending generally parallel to said axis and having opposite end portions, a cutter mounted on said holder, one of said end portions being pivotally connected to said head at a pivot connection for swinging motion of said holder to move said cutter toward or away from said axis, and adjustment means for adjusting both of said end portions inwardly and outwardly relative to said axis.
Claim 2
Dependent Claim
88 words
Apparatus for internally peeling tubes comprising: a peeling head having a longitudinal axis about which said head is rotatable, an elongated cutter holder extending generally parallel to said axis and having opposite end portions, a cutter mounted on said holder, one of said end portions being pivotally connected to said head at a pivot connection for swinging motion of said holder to move said cutter toward or away from said axis, and adjustment means for adjusting both of said end portions inwardly and outwardly relative to said axis.
Claim 3
Dependent Claim
41 words
The apparatus of claim 1 wherein said pivot connection includes a pin extending outwardly of said axis and being attached to said head for swinging movement thereof toward and away from said axis, and said holder being attached to said pin.
Claim 4
Dependent Claim
25 words
The apparatus of claim 2 wherein said holder is adjustably attached to said pin for adjustable movement therealong to define part of said adjustment means.
Claim 5
Dependent Claim
70 words
The apparatus of claim 2 wherein said pin is outwardly curved at one pin end and said head has a socket receiving said one pin end for swinging movement of said pin in said socket, said pin having an opposite pin end which is outwardly curved at a greater radius of curvature than said one pin end, and said head having a curved guide surface adjacent said opposite pin end.
Claim 6
Dependent Claim
44 words
The apparatus of claim 4 wherein said pin has an intermediate pin portion between said ends of non-circular cross-sectional shape, said holder having a guideway receiving said intermediate pin portion, and releasable clamping means for releasably clamping said holder to said intermediate pin portion.
Claim 7
Dependent Claim
16 words

Claim 8
Dependent Claim
64 words
Apparatus for internally peeling tubes comprising: a cutter head having a longitudinal axis, a cutter holder having opposite end portions, and mounting means for mounting said holder to said head for swinging movement of said holder outwardly and inwardly relative to said axis about one of said end portions and for adjusting movement of both said end portions toward and away from said axis.
Claim 9
Dependent Claim
64 words
Apparatus for internally peeling tubes comprising: a cutter head having a longitudinal axis, a cutter holder having opposite end portions, and mounting means for mounting said holder to said head for swinging movement of said holder outwardly and inwardly relative to said axis about one of said end portions and for adjusting movement of both said end portions toward and away from said axis.
Claim 10
Dependent Claim
25 words
