Manufactured by THURLEY GRIP-ALL Co. - London GB
Assigned to THURLEY GRIP-ALL Co. - London GB

Improvement to the design in GB-215,553, with the adjustment means being "rack" teeth on the adjustable jaw and attached to the handle. The THURLEY GRIP-ALL (Introduced in 1925 and marked with patent no. GB-215,553) appears to use this adjustment means. A March 1928 item notes the wrench was shown by ALFRED HERBERT, LTD (Coventry) at a trade show.

Assigned to Wald Mfg. Co. - Maysville KY

The tool stretches and inserts a "rubber band" type plug into a puncture hole in pneumatic "tubeless" tires. The design in this patent differs from a known example of the WALD BEATS-ALL Tire Repair Tool. That example matches the design shown in a January 1921 ad, when WALD was located in Sheboygan, WI, and a similar WALD REPAIR TOOL design is shown in 1912 Sears, Roebuck & Co. Catalog No. 124.

APPL'D vise roughly matching this patent was introduced a decade later when DuCharme was in Cleveland.
