Manufactured by Bonney Vise & Tool Works, Inc. - Philadelphia PA
Assigned to J. Edward Durham - Philadelphia PA

A spring in the adjusting mechanism keeps the adjusting screw tight to the adjusted member, so that motion of the screw positively changes the position of the adjusted portion. The drawing shows the concept as applied to a vise and adjustable end wrench. The patent appears on an adjustable end wrench, marked "BONNEY // ALLENTOWN".

Manufactured by Practical Tools Co. - New York NY

The patent presents two alternate head structures; one where the overall angle of the head is adjustable in relation to the handle, and the other with the head fixed to the handle. Both structures have a fixed jaw with one sloping & toothed face for use as a pipe wrench and a flat face at right angle to the movable jaw for nut wrench purposes. Both structures have a movable jaw which can be set to bear either against flat nut wrench face or sloping pipe wrench face. Only the "fixed head" variant shown in figs. 1 & 2 was produced. Carll wrenches are found with a variety of markings suggesting a succession of production companies. Initially produced in 6" and 10" sizes. A 1920 write-up for the wrench gives Practical Tools Co. as the manufacturer with M. W. Robinson Co. as sales agent -- both firms having the same address - 296 Broadway, New York City. That write-up notes the maximum "safe" jaw openings for 6", 8" and 10" wrenches. A similar reversible jaw appears in the January 19, 1897 Canfield patent (no. 575,592).
