Assigned to Victor Manufacturing Co. - Dayton OH

The geometry of the swinging loop ends and the lobes on the handle extending into those loops are such that the wrench will bear on the sides of hexagon nuts and bolt heads. The design is intended to provide a type of ratchet action, and to lessen the chance of damaging the corners of hexagon nuts and bolts. Produced as the VIMCO wrench, with initial sales and promotion from an Omaha, NE address. Compare this to J.E. Meredith's 1898 patent (no. 651,574 is the U.S. version).

The gripping sections are riveted to the handles; a spring tends to open the grip. The specifications note application on Mason jars; the illustration shows a "zinc" lid with glass inner lid and rubber seal ring between the lid and jar shoulder. A known example does not show evidence of ever having any permanent markings. Dudek's CAP WRENCH and JAR CLAMP (pat. no. 1,410,390) appear in a June 1922 NEBRASKA IRONMONGER ad, with address given as 2222 Y Street, Lincoln, NE.

Manufactured by Lawson Mfg. Co. - Cleveland OH

The adjustable jaw passes through a slot in the shank, with the adjusting knurl in a second slot at right angles. The patent describes "C" springs inside the adjusting knurl which act to hold the adjustment, but these springs aren't found in known examples. Improved by Lawson's Nov. 5, 1929 patent (no. 1,734,734). The form is very similar to the FRANKLIN pipe wrench as produced by Eaton, Cole and Burnham (patent no. 345,777).
