Manufactured by Imperial Mfg. Co. - Jersey City NJ

Combination quick and screw adjust wrench with a slide-on auxiliary pipe jaw. A stiff spring on the back side of the movable jaw allows the jaw to be shifted sufficiently to slide freely, and keeps the adjusting screw engaged with teeth cut in the face of the main shank. Production information for a bicycle wrench version taken from an Aug. 3, 1893 IRON AGE announcement. That announcement does not show the pipe jaw attachment. Ken Cope's "American Wrench Makers 1830-1930" notes Imperial Mfg. Co.'s production of larger sizes that included the supplemental pipe jaw. The markings on the 12-inch wrenches in the 3rd image are: (top) Imperial MFG. Jersey City, N. J. // Hitt’s Patent May, 19, 1891 Drop Forged Steel (bottom) "Cobin, Hitt M’F’G’ Co. Jersey City N. J. // Pat. May 19, 1891"

"Tweak" on the Stillson type pipe wrench includes the location and shape of the springs between the handle and frame for the adjusting nut. The pivot point between the handle and frame is a pair of lugs on the handle, and corresponding grooves in the frame so that the parts can be assembled without the use of a rivet or pivot pin.
