Harry Scheffer Prussia, Germany, patented quick adjust wrench. Patent 741,841, patented October 20, 1903. Manufactured by Remsheid Haddenbach Germany. Mine is 10 inches long, they can be found in different sizes but I'm not sure how many different sizes were offered.

Simple design, interesting. The harder you "wrench" the tighter it grips. Have you tried it ?
