Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
184 words
A hand tool for cutting the shielding of a shielded conduit comprising: a first elongated handle member having a hinge end and a free end; a circular saw carried by said first member adjacent its free end in a position such that its cutting plane is parallel to the longitudinal axis of said first member; a second elongated handle member defining a cable-receiving channel, having a hinge end and a free end, hingedly connected to said first member at the hinge ends of said members, and being provided with a longitudinally disposed slot which is adjacent the free end of said second member and lies in the cutting plane of the circular saw; stop and guide means between said first and second members, adapted to control and delimit the relative hinging movement of said members; a third elongated member disposed substantially parallel to the second member and hingedly connected thereto adjacent the free end thereof; cable clamping means carried by said third member and being movable thereby toward and away from cable clamping position; and means for limiting the movement of said third member.
Claim 2
Dependent Claim
184 words
A hand tool for cutting the shielding of a shielded conduit comprising: a first elongated handle member having a hinge end and a free end; a circular saw carried by said first member adjacent its free end in a position such that its cutting plane is parallel to the longitudinal axis of said first member; a second elongated handle member defining a cable-receiving channel, having a hinge end and a free end, hingedly connected to said first member at the hinge ends of said members, and being provided with a longitudinally disposed slot which is adjacent the free end of said second member and lies in the cutting plane of the circular saw; stop and guide means between said first and second members, adapted to control and delimit the relative hinging movement of said members; a third elongated member disposed substantially parallel to the second member and hingedly connected thereto adjacent the free end thereof; cable clamping means carried by said third member and being movable thereby toward and away from cable clamping position; and means for limiting the movement of said third member.
