Description: |
| A spring tensioned sliding face piece within the adjustable movable jaw structure allows for "ratchet" action on hex and square nuts.
The patent discusses alternate structures to accomplish this objective, including option to "lock out" the ratchet feature.
The patent appears to correspond to the PALM WRENCH advertised and produced by DeLisser Mfg. & Export Corp. ca. 1920. The company listed three sizes: 7, 9 and 11 inch with the 11 inch having a 7/8 inch capacity. A known example is marked, "PALM WRENCH / PAT APPLD FOR // DELISSER MFG. & EXPORT CORP. / NEW YORK " |
