Manufactured by Ridge Tool Co. - Elyria OH

The wrench is identical to the patent drawing. Earliest ads for this style show "PAT. PEND"G" markings and malleable iron handles; example shown in 2nd image is marked "RIDGID PAT 1727623 // RIDGE TOOL CO ELYRIA O U.S.A." Ads from 1937 demonstrate a modified appearance introduced during that year -- additional material added to the fixed jaw resulted in a "chevron," and Dec. 1937 ad includes "alloy handle" in the description. The wrenches with this patent number have many features carried over from Thewes' Sept. 1, 1925 patent (no. 1,552,091).

Manufactured by Helm Tool Co. - Chicago IL

" This invention relates to a universal joint, and more particularly to such joints that can be made in groups having a plurality of units for increasing or varying the angle between the axis of the driving element and the axis of the driven element. The present invention is an improvement over that disclosed in the patent to Helm & Derleg No. 2,760,358, granted August 28, 1956. In the use of mechanic's tools, it often occurs that a considerable angle exists between the axis of the driven element and the available position for the axis of the driving element. By the use of the present invention I have made it possible to transmit such driving force through angles greater and less than three hundred and sixty degrees. " The patent number appearing on a known example marked "THOR" reflects manufacture for distribution by Independent Pneumatic Tool Co. (Aurora, IL). Also distributed by Snap-On. An extensive "GARAGE JOURNAL" discussion about the tool provides context and additional details.
