Stan Schulz Bullard Wrench history snippets -- (FLICKR)

Description: |
The BULLARD wrench was invented by a Los Angeles physician; one mention in a local professional journal noted he was also a "poet and inventor." This patent was a modification of earlier designs ( 729,728 and 733,138 ) which are not known to have been produced.
The gripping action is an approximation of the way a thumb and fingers grasp objects -- this is reflected in some ads published by the 2nd manufacturer. The design is reflected in wrenches of obscure (including German) origin, bearing names like "Plattina," "EDISON," etc. |
