US Patent: 1,276,596 http://www.datamp.org/patents/displayPatent.php?id=37132&pn=1,276,596 Work Gripping Tool Patentee: William O. Vivarttas - Weehawken NJ Granted:1918-08-20
Manufactured by Efficiency Device Corp. - New York NY

The main feature of the patent is the coil spring which tends to close the loop or hook jaw against the gripping surface on the handle. It is described as being suitable for a lathe-dog or pipe wrench. Both the pipe wrench and lathe dog are shown in 1919 - 1920 EFFICIENCY DEVICE CORP. ads and hardware trade journal notices. Efficiency Device Corp's STIX-ON WRENCH made of stamped parts has a spring-tensioned hook jaw and this patent date. Vivarttas' Sept. 18, 1923 patent (no. 1,468,529) adds refinements to the wrench application of the concept, and more closely matches the STIX-ON WRENCH.

US Patent: 1,299,764 http://www.datamp.org/patents/displayPatent.php?id=58353&pn=1,299,764 Wrench Patentee: Daniel J. Normoyle - Philadelphia PA Granted:1919-04-08
Manufactured by Alert Tool Company - Philadelphia PA
Assigned to Alert Tool Company - Philadelphia PA

Tap wrench with ratchet action and provision for having the handle "centered" or extending entirely to one side. An internal spring normally keeps the handle body engaged with the splined shaft holding the chuck; compressing the spring disengages the handle and allows it to be re-positioned. Unscrewing the top "button" allows the shaft to be completely withdrawn from the handle body, and then the rod handle can be set so either the center or end hole is used when the parts are reassembled. It was featured on the front cover of July 3, 1913 AMERICAN MACHINIST. An early version of the ALERT RATCHET TAP WRENCH was advertised in 1911.
