In practice when it is desired to adjust the wrench to a nut or pipe the fixed jaw is engaged with the same and the sliding jaw is then moved up until it also engages. The wrench-handle and the detent-handle are now both tightly grasped, which will cause the detent-finger to engage one of the teeth on the sliding jaw, whereby said jaw will be firmly held against the object and cannot slip or work back as long as the handles are held together.

The working faces of both jaws are provided with the usual serrations for gripping the objects with which they are engaged.

From the foregoing description,taken in connection with the accompanying drawings, the construction and operation. of the invention will be readily understood without requiring a more extended explanation.

Various changes in the form, proportion,

and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

In a combined nut and pipe wrench, the combination with a fixed jaw, having two working faces, of a sliding jaw having two corresponding working faces, one of which faces is pivotally connected to said sliding jaw, an adjusting-screw carried by said jaw whereby an independent adjustment may be given said pivoted working face, an inclined toothed surface formed on said sliding jaw, a pivoted detent adapted to engage said inclined toothed surface whereby said sliding jaw may be held in adjusted positions, and a handle fixed to said detent for operating the same, substantially as described.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

- JOSEPH II. FLANIGAN.
