What I claim is—

1. The combination in a wrench of the body portion having a stationary jaw and an integral extension, said extension having holes F and T, the movable jaw having the extended too threaded portion fitted into said hole D, the nut S fitted into said hole P and engaging the threaded portion of the movable jaw, the extension being cut away on one side, and a spring K, arranged below the nut in the cut away portion of the extension, and bearing against the threaded portion of the movable jaw, and tending normally to force the jaws together, the screw-threaded portion of the movable jaw being loosely mounted in the hole D to permit of this movement, substantially as described.

2. The combination in a wrench of the body portion having the fixed jaw and the integral extension, the movable jaw having an extended threaded shank fitted loosely in said extension, a slot or aperture in said extension, a nut fitted into said slot, and threaded on to the extended shank of the movable jaw, the pins P and Q mounted in said extension below the nut, and the spring R, said spring being bent around the pin P, and bearing against the body portion of the wrench, and haying a loop r fitted around the pin Q where by the tendency of the spring is to bear on the extended threaded shank of the movable jaw so as to normally force the jaws together, substantially as described.

3. The combination in a wrench of the body portion A having the extension C, the holes D and F cut in said extension C, and the recesses E and I also cut into said extension C, whereby there are left united bridge pieces H and H', and G and G', the pin P inserted in the bridge G, and the pin Q inserted in the bridge G', the spring R mounted on said pins, the movable jaw K having the extended threaded shank J fitted in said hole D, and the nut S fitted in said hole F, and engaging the threaded shank J, said shank J being loosely mounted in the hole D, said spring R bearing on said shank, so as to normally force the jaws of the wrench together, substantially as described.

Ken Cope's "American Wrench Makers 1830-1930" asserts Spiers produced this wrench, based on the assignment.
