Abstract
Abstract A conduit-cutting tool generally comprising pliers having a pair of opposed jaws with slots therein adapted to receive a hacksaw blade therethrough, said jaws being adapted to hold a conduit in position to be cut when said hacksaw blade is reciprocated through said slots; and a brace bar coupled to one jaw of said pliers and adapted to be hooked around a stud or rafter in opposition to the opposite one of said jaws, whereby the pliers may be braced in such a manner that the jaws will be forced together and held steady, while the saw blade is reciprocated through said slots to accurately cut off a conduit between said jaws.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
162 words
In a conduit-cutting tool, the combination of: a pair of manually operable pliers having a pair of respective opposed jaws adapted to engage and clamp oppositely against conduit; said jaws having aligned saw blade-guiding slots therein; said slots extending in a direction and disposition diametrically to overlap the diametrical extremities of a conduit when clamped between said jaws; a pair of handles pivoted together and supporting said pair of jaws so as to pivotally actuate said jaws toward and away from each other, said handles disposed to be manually squeezed together by one hand of a human operator, while the other hand of said operator may reciprocate a saw blade through said slots to cut off said conduit held between said jaws; and a brace bar secured to one of said jaws and including means at its outer end for temporarily securing said tool to a stationary structure for bracing said pliers when said saw blade is used to cut said conduit.
Claim 2
Dependent Claim
162 words
In a conduit-cutting tool, the combination of: a pair of manually operable pliers having a pair of respective opposed jaws adapted to engage and clamp oppositely against conduit; said jaws having aligned saw blade-guiding slots therein; said slots extending in a direction and disposition diametrically to overlap the diametrical extremities of a conduit when clamped between said jaws; a pair of handles pivoted together and supporting said pair of jaws so as to pivotally actuate said jaws toward and away from each other, said handles disposed to be manually squeezed together by one hand of a human operator, while the other hand of said operator may reciprocate a saw blade through said slots to cut off said conduit held between said jaws; and a brace bar secured to one of said jaws and including means at its outer end for temporarily securing said tool to a stationary structure for bracing said pliers when said saw blade is used to cut said conduit.
Claim 3
Dependent Claim
40 words
The invention, as defined in claim 1, wherein: said brace bar is generally hook-shaped and adapted to hook around one side of a building stud or rafter, while said pliers are engaged with an opposite of said stud or rafter.
Claim 4
Dependent Claim
25 words
The invention, as defined in claim 1, wherein: said jaws are generally L-shaped in cross section, and thereby adapted to engage conduit of varying diameters.
Claim 5
Dependent Claim

The invention, as defined in claim 2, wherein: said jaws are generally L-shaped in cross section, and thereby adapted to engage conduit of varying diameters.
Claim 6
Dependent Claim
18 words
The invention, as defined in claim 1, wherein: said slots extend through said jaws and into said handles.
Claim 7
Dependent Claim
58 words
The invention, as defined in claim 5, wherein: said brace bar is generally hook-shaped and adapted to hook around one side of a building stud or rafter, while said pliers are engaged with an opposite side of said stud or rafter; said jaws being generally L-shaped in cross section, and thereby adapted to engage conduit of varying diameters.
Claim 8
Dependent Claim
27 words
The invention, as defined in claim 2, wherein: one jaw of said pliers is adapted to oppose said brace bar in engagement with said stud or rafter.
Claim 9
Dependent Claim
35 words
The inventIon, as defined in claim 7, wherein: the other of said jaws carries said brace bar, such that force on said brace bar engaging a stud or rafter tends to force said jaws together.
