WIRE CLAMPING TOOL FOR TENSIONING,
TWISTING AND SEVERING
Charles E. Hunziker, 174 Paramus Road, Paramus, NJ.
Filed Aug. 4, 1960, Ser. No. 47,462
5 Claims. (Cl. 140-4235)
My invention relates to tools and more particularly to
a tool operable for stretching and clamping wire or the
like about an object.
One of the objects of my invention is to provide a wire
stretching and clamping tool which is capable of being
slidably mounted a rod 21 having its inner end disposed
out of the bore and formed with a transverse opening 22
in proximity to the hub for receiving therethrough the
other end section 23 of the wire W. The other or outer
end of the rod '21 extends outwardly through the outer
end of the arm 16 and has threaded thereon an adjusting
nut 24 for engaging the outer end of the arm for moving
the rod relative to the arm upon rotation of the nut.
One face of the arm d6 is formed with a slot in which is
received a pin 25 carried by the rod 21 and which pin
serves to engage the ends of the slot for limiting the
movement of the rod within the bore and preclude acci
dental removal of the rod therefrom.
