Description: |
| Abstract from ESPACENET: "The movable jaw D carries a worm E, which may be put in or out of gear with the teeth F on the stem B. When the parts are out of gear, the jaw D may be slid rapidly along the stem, and when the parts are in gear a fine adjustment may be given to the jaw D by turning the worm E. The worm turns on a spindle G, which is eccentrically pivoted and carries projections J which serve as stops and as means for turning the spindle."
The specifications note this invention comes from George Belle Jones of Chicago, Illinois.
Ron Geesin's THE ADJUSTABLE SPANNER shows this design produced by Swinden as the Instantaneous Grip Spanner.
