Abstract

Abstract Set out herein is an improved conduit cutting guide including a longitudinally hinged handle formed in the manner of a trough and lined with segments of rubber or plastic for grasping the surfaces of a spirally wound flexible conduit therein. One end of the handle is attached to a first set of J-shaped end plates, each end plate being respectively fixed to one of the hinged portions of the handle, the first set of end plates extending above the handle trough to form two outwardly and downwardly directed end tabs. A second set of J-shaped end plates is attached to the respective first set, the second end plates being similarly conformed in plan form and include an offset for receiving the hacksaw blade therebetween. Thus, a conduit may be placed into the interior of the hinged handle and may be grasped thereat by the user. A hacksaw is then insertable into the space between the first and second sets of end plates for cutting the conduit.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 134 words
Apparatus for guiding the cutting of flexible conduit by way of a saw comprising: a handle conformed as a hollow semicircular segment having two longitudinally hinged portions aligned to pivot relative each other for defining cavity of varying lateral dimensions therebetween into which said conduit may be placed; flexible lining means adhesively secured on the interior of said cavity to the interior surfaces thereof; a first set of substantially J-shaped end plates respectively secured to one end of said portions in a plane substantially orthogonal to said cavity, said first set of J-shaped end plates being conformed to define an opening therebetween substantially equal to the end of said cavity; and a second set of J-shaped end plates attached in spaced relationship over said first set of end plates to define a gap therebetween.
Claim 2
Dependent Claim 134 words
Apparatus for guiding the cutting of flexible conduit by way of a saw comprising: a handle conformed as a hollow semicircular segment having two longitudinally hinged portions aligned to pivot relative each other for defining cavity of varying lateral dimensions therebetween into which said conduit may be placed; flexible lining means adhesively secured on the interior of said cavity to the interior surfaces thereof; a first set of substantially J-shaped end plates respectively secured to one end of said portions in a plane substantially orthogonal to said cavity, said first set of J-shaped end plates being conformed to define an opening therebetween substantially equal to the end of said cavity; and a second set of J-shaped end plates attached in spaced relationship over said first set of end plates to define a gap therebetween.
Claim 3
Dependent Claim 35 words
Apparatus according to claim 1 wherein said first set of end plates include end tabs bent to extend over said gap; and said second set of end plates includes ends aligned outwardly from said gap.
Claim 4
Dependent Claim 14 words
Apparatus according to claim 2 wherein: said portions comprise surface segments of a tube.
Claim 5
Dependent Claim 22 words
Apparatus according to claim 3 wherein: said second set of end plates are adjustably secured to said first set of end plates.
