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.
