GEORGE W. HUGHEY, OF SPRINGFIELD, MISSOURI.

WRENCH.

Application filed November 30, 1915.

Z '0 all whom it may concern:

Be it known that I, GEORGE IV. HUGHEY, a citizen of the United States, residing at Springfield, in the county of Greene and State of Missouri, have invented new and useful Improvements in lVrenches, of which the following is a specification.

This invention relates to wrenches, and one of the objects thereof is to provide a simple, cheap and eflicient device capable of rapid and reliable adjustment.

Another object of the invention is to construct a wrench with a rigid jaw having a longitudinally slotted shank, to arrange a slidable jaw upon the shank, and to pro vide the slidable jaw with a pivoted hinged locking part which may be swung to frictionally engage with the inner edges of the bifurcated portion of the wrench and to positively lock the jaw upon the shank.

With the above and other objects in view, the improvement resides in the construction, combination and arrangement of parts set forth in the following specification and falling Within the scope of the appended claims.

In the drawings: Figure 1 is a view in side elevation of a wrench constructed in accordance with the present invention, Fig. 2 is a central longitudinal sectional view through the same, Fig. 3 is a transverse section through the sliding jaw, Fig. 4.- is a similar section taken through the shank and through the locking block of the sliding jaw, Fig. 5 is a perspective view of the sliding jaw, Fig. 6 is a similar view of the looking block.

The wrench, in the form shown in Figs. 1 to 6, has its shank 1 provided with a laterally extending head 2 forming the same with jaws disposed one to each of the opposite sides of the shank, and one of the said jaws preferably has its working face toothed, as indicated by the numeral 3.

The shank 1 is slotted longitudinally, providing the same with a pair of spaced bars 4P4, and the inner edges of these bars are provided with teeth 5.

The numeral 6 designates a handle which is removably secured to the reduced end of the shank, and the removal of this handle permits of the arrangement 4 on the said shank of a slidable jaw 7. The slidable member 7 comprises a head member having spaced slots or passages 8-8 through which bars 4- 1 of the shank 1 pass, and the said member is provided at the opposite sides of Specification of Letters Patent.

Serial No. 64,322.

the mentioned jaws with heads which are adapted to co-act with the jaws provided by the head 2. One of these jaws has transs 'erse teeth 9 which are adapted to co-act with the toothed jaw 3 of the head 2.

The end of the member 7 opposite that provided with the jaws is centrally formed with a lug 10 which is adapted to be received between spaced ears 11-11 provided upon a locking block 12.

The numeral 18 designates a pintle which passes through the cars 11 and the lug 10 whereby the block 12 is hingedly secured to the sliding member 7. The block 12 has its sides provided with teeth 14- which are adapted to engage with the teeth 5 of the arms 4 of the shank 1, when the block is swung between the said arms. In this connection it should be stated that the teeth of the bars as Well as the teeth of the block are arranged at a curve, so that the said block may be swung to either side of the shank 1 when the member 7 is to be slid upon the said shank. Also preferably the space between the teeth, at the outer sides or faces of the memberselis slightly widened to permit of the ready engagement of the {)eeth of the block between the teeth of the ars.

In order to retain the block between the bars 4 to hold the sliding jaw 7 in an adjusted position, I provide a catch member including a central portion or stem 15 which passes transversely through an opening in the block and which has its ends provided with spring arms 1616 which are of a width sufficient to be brought over the side or faces of either of the bars 4-. The arms 16 are constructed preferably of spring material and the ends of both are preferably flared outwardly and one of said ends is provided with a handle 17 whereby the catch may be readily actuated.

Having thus described the invention, what I claim is:

1. A wrench h. ving a rigid jaw provided the same with spaced bars, the inner edges of which are toothed and the distance between the teeth is greater at the ends of the teeth than at the central portions of the teeth, a sliding jaw carried by the wrench, a pivoted block on the aw, said block having its edges toothed to engage with the teeth of the bars, a latch for the block comprising a member passing transversely through an opening in the block and having its ends provided with spring arms of a length to engage with the shank at the opposite sides of its slots and one of said spring arms being provided with a handle.

3. A wrench having a rigid jaw provided with a longitudinally slotted shank, the inner edges of which are provided with rounded teeth and the distance between the teeth is greater at the ends thereof than at the central portion, a sliding jaw carried by the shank, a pivoted block for the jaw, said block having its ends formed with teeth to engage with the teeth of the slotted shank and a latch member upon the block operable from either side thereof to lock the block upon the shank.

In testimony whereof I affix my signature in presence of two witnesses.

GEORGE \V. HUGHEY. \Vitnesses Cmnnxcn E. HUGi-IEY, XENIPHON HAWKINS.
