Abstract
Abstract Apparatus for cutting flexible tubing such as hose by means of a hand tool having a rotary cutting wheel. The apparatus includes a slide plate and structure for guiding the hand tool, herein more specifically a circular saw, in a preselected path with the cutting wheel passing through the apex of an arcuately retained hose portion. The apparatus includes improved adjustable structure for holding different size hoses in the arcuate configuration for suitable cutting by the wheel.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
147 words
Apparatus for cutting flexible tubing by means of a hand tool having a rotary cutting wheel, comprising: a slide plate having a horizontal slide surface and a slot opening therethrough; means on said plate for guiding the hand tool separably horizontally along said slide surface with the cutting wheel projecting through said slot into a cutting space adjacent the opposite surface of said plate; and holding means, said holding means connected to said slide plate for holding flexible tubing in a vertical arcuate configuration with the apex of the arcuate configuration uppermost and adjacent said slot in said cutting space to be cut by the horizontal translation of said hand tool cutting wheel therethrough substantially horizontally transaxially of the tubing, said hose being backed-up by said holding means and positively retaining the hose against horizontal displacement in the direction of the translation movement of the saw therethrough.
Claim 2
Dependent Claim
147 words
Apparatus for cutting flexible tubing by means of a hand tool having a rotary cutting wheel, comprising: a slide plate having a horizontal slide surface and a slot opening therethrough; means on said plate for guiding the hand tool separably horizontally along said slide surface with the cutting wheel projecting through said slot into a cutting space adjacent the opposite surface of said plate; and holding means, said holding means connected to said slide plate for holding flexible tubing in a vertical arcuate configuration with the apex of the arcuate configuration uppermost and adjacent said slot in said cutting space to be cut by the horizontal translation of said hand tool cutting wheel therethrough substantially horizontally transaxially of the tubing, said hose being backed-up by said holding means and positively retaining the hose against horizontal displacement in the direction of the translation movement of the saw therethrough.
Claim 3
Dependent Claim
33 words
The apparatus for cutting flexible tubing of claim 1 wherein said guiding means comprises means adjustably mounted on said plate to accommodate any one of a plurality of hand tools having different configurations.
Claim 4
Dependent Claim
31 words
The apparatus for cutting flexible tubing of claim 1 wherein said means for holding the flexible tubing comprises adjustable means for accommodating any one of a plurality of different size tubing.
Claim 5
Dependent Claim
32 words
The apparatus for cutting flexible tubing of claim 1 further including means for limiting the movement of the hand tool in a direction longitudinally of said slot rearwardly from said cutting space.
Claim 6
Dependent Claim
32 words
The apparatus for cutting flexible tubing of claim 1 wherein said slide plate comprises a pair of portions spaced apart to define said slot therebetween and means fixedly connecting said plate portions.
Claim 7
Dependent Claim
52 words
The apparatus for cutting flexible tubing of claim 1 wherein said slide plate comprises a pair of portions spaced apart to define said slot therebetween, said means for holding the flexible tubing including a support fixedly connected to each of said plate portions retaining said plate portions in the spaced apart arrangement.
Claim 8
Dependent Claim
36 words
The apparatus for cutting flexible tubing of claim 1 further including a guard plate fixedly connected to each of said plate portions at a rearward portion thereof retaining said plate portions in the spaced apart arrangement.
Claim 9
Dependent Claim
105 words
The apparatus for cutting flexible tubing of claim 1 wherein said slide plate comprises a pair of portions spaced apart to define said slot therebetween, said means for holding the flexible tubing including a support fixedly connected to each of said plate portions, and further including means for limiting the movement of the hand tool in one direction longitudinally of said slot forwardly of said cutting space, said limiting means defining a stop member fixedly connected to each of said plate portions, said support and stop members being spaced apart longitudinally of said slot and cooperatively retaining said plate portions in the spaced apart arrangement.
Claim 10
Dependent Claim
55 words
The apparatus for cutting flexible tubing of claim 1 wherein said means for holding the flexible tubing includes a support, means on the support for supporting the apex of the tubing arcuate configuration, and means adjustable solely parallel to the slide surface for engaging the tubing to deflect the tubing about said apex supporting means.
Claim 11
Dependent Claim
49 words
The apparatus for cutting flexible tubing of claim 9 wherein said last named adjustable means comprises a plurality of holes spaced apart perpendicular to said slide surface at opposite sides of said cutting space and pin means selectively received in selected ones of said holes for engaging said tubing.
Claim 12
Dependent Claim
67 words
The apparatus for cutting flexible tubing of claim 1 wherein said means for holding flexible tubing in an arcuate configuration comprises a support, means on the support for supporting the apex of the tubing arcuate configuration and means adjustable substantially along a straight line for deflecting the tubing about the apex supporting means, and means movably supporting a cutting means for movement transaxially through said tubing apex.
Claim 13
Dependent Claim
42 words
The apparatus for cutting flexible tubing of claim 11 wherein said means for deflecting the tubing comprises a plurality of holes spaced apart by said straight line and pin means selectively received in selected ones of said holes for engaging said tubing.
Claim 14
Dependent Claim
45 words
The apparatus for cutting flexible tubing of claim 11 wherein said means for supporting the apex of the arcuate configuration comprises a pair of elements separately fixed to said support to define a space therebetween for receiving the cutting wheel during a tubing cutting operation.
