Description: |
A strap wrench in which the "anchored" end of the strap slides through a slot in a cross member in the head, and is held in place by the pressure of the strap against the final portion of the strap.
The design appears to correspond to the "WARNOCK SIMPLEX" strap wrench; patent no. 1,023,533 is a further evolution of the design. |
