SPECIFICATION `forming part of vLettersl/Patent No. 780,743, dated January 24, 1905. Application filed October 13, 1904:.r Serial No. 228,271.

vTo @ZZ whom it may con/cern.' Y

Be it known that I, SAMUEL J. GLOKEY, a citi- Zen of the United States of America, residing at Washington, in the county of I/Vashington and State of Pennsylvania, have invented certain new and useful Improvements in Wrenches, of which the following is a specication, reference being had therein to the accompanying drawings.

This invention has relation to certain new and useful improvementsv in wrenches, and more particularly vto that type commonly known as a monkey-wrench.

This invention has for its object the provision of a novel form of wrench which may be readily used as a pipe-wrench, and. I have provided novel means whereby said wrench may be quickly changed to a pipe-wrench, also means whereby the sliding jaw of said wrench may be quickly adjusted to any desired position and then more finely adjusted to place the sliding jaw in a more firm engagement with an object.

Briefly described, my improved wrench comprises a shank having a handle secured upon its onev end and a detachable jaw upon its other end. Upon this shank is slidingly mounted an adjustable jaw having a pivoted handle which is adapted to engage with a toothed bar adj'ustably mounted'within the shank of the wrench.

The above construction will be hereinafter more Jfully described, and specifically pointed out in the claims.

In describingV the invention in detail reference is had to the accompanying drawings, forming a part of this application, and wherein like numerals of reference indicate. like parts throughout the several views, in which-n Figure 1 is a side elevation of my improved wrench. Fig. 2 is a vertical sectional view of the same. Fig. 3 is an edge view of the wrench., the jaws thereof being shown in vertical section. Fig. 4 is aperspective view of a handle carried by the adjustable jaw. Fig. 5 is an underneath perspective view of a modified form of adjustable jaw detached from the shank and from the handle. Fig. 6 is an underneath perspective view of a modified form of stationary jaw detached from the shank.

To put my invention into practice, I em-V ploy a-shank 1,'having a tapering screwthreaded end 2, upon which the handle 3 is secured bya nut 4C. The upper end of the shankis 'providedwith an aperture 5, and upon this endis secured by a pin 6 a jaw 7, which upon its under face is providedwith a recess 8, with which communicate apertures 9 9, whereby the pin 6 may be placed in said 'apertures and the aperture 5 to secure the jaw upon the upper end of the shank. The shank upon its one edge is cut away, as indicated at 10, and the upper'edge of the cutaway portion isprovided with a recess, 11 and the rear wall of the cut-away portion near the lower end is provided with a recess 12. In said` cut-away portion is mounted a toothed bar 14, which is held in said recess by a pin 15, which protrudes into the recess 11, and by a screw 16, which is mounted in the cut-away portion between the lower end of the toothed bar and the base of said cut-away portion. The screw 16 is provided with a knurled nut 17, which is fixed on the screw andv which is adapted to lie within the recess 12 of said cutaway portion. The shank is further out away, as indicated at 18, and secured upon said c utaway portion by screws 19 is a retaining guide-plate 20, `said plate extending upwardly a suicient distance to bear against the toothed bar 14 and retainthe same in the cut-away portion of the shank.

Upon the shank 1 is mounted a sliding' jaw 21, which upon its under face is provided with a depending lug 22, and to this lug is pivotally connected by a pin 23 the handle 24. The said handle near its pivoted end and upon its inner face is provided With a tooth 25. This tooth is normally adaptedto engage two of' the teeth of the toothed bar 14, and in order that said tooth 25 may be held in engagement with. the toothed bar I have provided the slot 26 in the handle 8, whereby the handle 24 may be drawn into engagement with the handle 3 and retained therein by the hand of the person manipulating the wrench.

- surfaces.

In Figs. 5 and 6 of the drawings I have illustrated detachable jaws which are similar in all respects to the jaws 7 and 21, with the exception that said jaws are provided with the serrated concave surfaces 27 and Q8, and these jaws are employed when the wrench is to be used as a pipe-wrench or for grippingcurved By removing the jaw 7 and then removing the jaw 2l from the shank of the wrench these auxiliary jaws may be placed upon the shank to provide a pipe-wrench. By the construction of the adjustable jaw it will be seen that the same may be quickly adjusted upon the shank and held in engagement with any desired object. Should the teeth of the bar 14 not be suiiicient to permit of a perfect engagement of the adjustable jaw with the object, the knurled nut 17 is rotated to 'raise said toothed bar and the adjustable jaw into further engagement with said object.

From the foregoing' description it will be observed that I have constructed my improved wrench upon as simple lines as possible and that the wrench may be quickly adjusted to grip a desired object, and while I have herein shown the preferred form of constructing the wrench it is obvious that various changes may be made in the details of construction without departing from the general spirit of my invention.

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

l. A wrench comprising a'recessed shank, a jaw rigidly attached to said shank, a slotted handle attached to the shank, a toothed bar mounted in the recess oi lthe shank, an adjusting-screw mounted in the recess in the shank below said toothed bar, a slidable jaw mounted on the shank, a lever pivotally attached to said slidable jaw, the said lever being provided with a tooth adapted to engage the said teeth of the said toothed bar and the said lever seating in the slot in the handle.

Q. A wrench comprising a shank, a removable jaw fixed on one end of the shank, a handle secured upon the other end or' the shank, a movable jaw mounted on the shank, a toothed bar arranged in a recess in the shank, a screw arranged in a recess in the shank below said toothed bar, a guide plate attached to the shank and extending in front of said screw and over a portion of the toothed bar, and a lever pivotally attached to the sliding jaw and having a tooth engaging said toothed bar.
