I am aware that prior to my invention it has been proposed to provide a nut-Wrench consisting of a handle portion having longitudinal recesses and a transverse opening and a sliding jaw having members which slide in the longitudinal recesses, one of the members being screw-threaded t0 engage a nut let into the transverse opening of the handle portion, and I therefore do not claim such construction broadly; but

lVhat I do claim as new, and desire to secure by Letters Patent, is-

l. A nut-Wrench comprising a handle portion A constructed to present a rigid jaw A2, looped grasping portion A', transverse opening a2 and longitudinal recesses a and CL having annular bearing-surfaces d3 and d4 therein, and a sliding jaw B having members b and b which slide in the longitudinal recesses ct and a', one of the members being screw-threaded together with a nut C let into the transverse opening d2 to engage the threaded member of the sliding jaw, substantially as shown and for the purpose set forth.

2. In a Wrench, the combination, with the sliding jaw having two members one of Which is threaded,of a handle portionhaving a rigid jaw, a looped grasping portion and longitudinal recesses which receive the members of the sliding jaw; a nut let into the handle portion to engage the threaded member of the sliding jaw, webs a5 extending inwardly from the upper part of the looped grasping portion; and a Wooden block D cut away at its upper end to iit into the loop and engage the webs therein, substantially as shown and for the purpose set forth.
