Abstract
A tool for breaking and removing the outer end of a snap tie, which has an area of weakness and a button outer end, includes a tubular barrel containing a first jaw and a lever extending into the barrel having a second jaw in opposition to the first jaw. The lever is pivotally connected to the barrel for rotating the second jaw toward the first jaw so that the button can be clamped and the snap tie twisted to break the tie bar at the area of weakness.
Claims3
A tool for engaging and removing the outer end of a snap tie comprising:
- a tubular barrel having first and second open ends for receiving the outer end of a snap tie;
- a first jaw removably mounted in said barrel and extending longitudinally along one side of the interior of the barrel from the first open end to the second open end;
- a notch in one end of the barrel;
- an elongated lever pivotally connected proximate one of its ends to the exterior of the barrel for rotation around an axis parallel to the longitudinal axis of the barrel, said one end of the lever extending through the notch in said one end of the barrel and being rotatable in the notch;
- a second jaw removably mounted on said one end of the lever in the barrel opposing said first jaw and extending longitudinally in the barrel from said first open end to the second open end, whereby, when either end of the barrel is placed over the outer end of the snap tie, the lever can be rotated between an open position and a clamping position around one end of the snap tie, and further rotated in the same direction to cause the snap tie to break at a zone of weakness therein.
