HARRY JEFFREY, OF LOUISVILLE, KENTUCKY, liSS IGNOR TO THE OHIO lvfALLElfB'LE IRON COMPANY, OF COLUMBUS, OHlO, A CORPORATION OF OHIO WRENCH;

T 0 all whom it may concern: 7

Be it known that I, HARRY- JEFFREY, a cltlzen'of the-Un1ted States, residing Louisville, in the county of Jefferson and,

pernahery of the head. By forming a groove 5 State of Kentucky, have invented certain new and useful Improvements in Wrenches, of which the following is a specifl .'ation, reference being had therein to the accompany ing drawing.

This invention relates toa combined spanner and socket wrench having all parts formed in a single piece of metal; and has for its object to provide a wrench, that can be easily and quickly placed upon any one of heads and can'be engaged with one of such difiering nuts either by moving the wrench head axially of the nut, while in position of engagement, or by movingit transversely of theaxis of the nut; and the wrench itself in all cases having a continuity of metal extending around the nut or bolt-head so that all of the parts subjected to strain shall be integral, and immovably tied together permanently, whereby great strength and d u rability are secured without increasing the thickness of-the metal over that used in making the ordinary, open-j aw solid wrenches.

Figure 1 is a face view of a wrench constructed with'my improvements. Fig. 2 is a face view taken from the opposite side. Fig, 3 is across section on the line X X of Fig. 1. Fig. 4 is a cross section on the line Y Y of Fig. 1.. Fig. 5 is an end view.

The wrench shown in the drawings is constructed with a shaft or handle 1, having an extension or head 2 at the end. This head is integral with the handle, and is so shaped as to have four jaw-like parts, 4, 5, 4 5

which are integral with the head and. handle, and are of substantially the same thickness asthe head.

Upon the face of the wrench shown in Fig. 1 there is formed in the head 2 a cavity indicated by 3, having walls 13, this being at the inner end and communicating with a groove 6 which extends outward from the Walls 13, 13, to the periphery of the head. This groove is of such nature that the wrench can be appliedto a nut having parallel sides of the width of the groove. If it be a hero agon nut of the right'size, the wrench can be engaged therewith at the walls 8, 8,13, 13.

Such engagement can be effected either by '55 bringing the Wrench to the nut on lines Specification of Letters Patent.

Serial No. 433,341.

parallel to the axis of the nut, or, in places where this can not be done, engagement can be attained by sliding the wrench along the nut, the latter entering the groove at the face shown in Fig. 2 of the wrench there 1 n r 1s formed a groove 1 having side walls 15, which extend into inclined walls 14. The metal at 4*, 5 on the sides of this groove 12, provides two i aw-like parts, connected at the bottom. of the groove by a tie-web or plate 18, which is integral with the jaws. This groove is narrower than that at 6 on the opposite f cc of the tool and is adapted to engage with and rotate nuts or bolts of smaller cross dimension. The groove 12 extends from the periphery inward to points beyond the inner end of the groove 6, and they are of such depth that there is at their inner ends a through aperture 7. It will be 4, 5, or those at 4"-, 5 are in use, they will be strengthened by the metal of the head and handle. At the o posite end the wrench is shown as provider with a smaller head, 16, which, vupon. one face is formed with a groove 17, and upon the other face with a groove 19, similar except in their dimen sions, to those at 6 and 12. This shows how a single piece of metal can be formed, in accordance with my invention, so that it can be utilized to engage with and rotate (either as a spanner wrench or as a socket wrench), nuts or bolt-heads of any of four sets.

I have not herein claimed this wrench broadly, such claims having been presented in my application Ser. No. 438,439, for the reissue of Patent No. 873,437.

Vt hat I claim is:

1. A wrench for enga ing nuts and boltheads comprising a ban le having integral therewith a head, having a central nut-receiving aperture extending through-the head and formed with a recess or groove in one of its faces, extending from the periphery of the head inward to the nut-receiving aperture and with a groove upon the opposite face eX- l riphery inward on the same: center line with tending from the periphery the head inward to the nut receiving aperture and alining with opposite faces thereof and narrower than the first aforesaid groove, said grooves providing two pairs of j aw-like parts 1n the head, each pair having integral with said jaw-like parts and with the handle a tie- Web or plate, substantially as set forth.

2. A wrench for nuts and bolt-heads comprising a handle having integral therewith a ead having a nut-receiving opening extending therethrough and formed with two pairs of jaw-like nut engaging parts, each jaw extending from the periphery of the headinward to the opening and, each pair of jaws being connected by an integral web, or tieplate, the jaws of one pair being closer together than the jaws of the other pair and the pairs of jaws being arranged on opposite side faces of the head, substantially as set forth. I

3. A wrench for nuts and boltheadscomprising a handle, having integral therewith a ead having a nut-receiving opening and formed with two pairs of j aw-like arts integral with the hea and handle an each pair of said parts having a relatively thin tic-web like parts of one pair extending from the pethe jaw-like parts of the other pair, the openings .of the jaw-like parts being directed oppositely from each other and the pairs of jaws being arranged on opposite side faces of the head, substantially as set forth.

5. A wrench for nuts and bolt-heads, oomprisin a handle having integral therewith a head orn'ied with two pairs of jaw-like parts integral with the head and handle, one pair on each side of the head and each pair having a relatively thin tie web or plate integral therewith, theinner face of one tie web lying in the same plane with the inner face of the other tie web and the pairs of jaws being arranged on oppositeside faces of the head.

6. A wrench for nuts or bolt-heads comprising a handle, having integral therewith a head formed with two pairs of jaw-like parts integral with the head and handle, each pair of said parts having a relatively thin tie web or plate integral therewith, one pair of jawlike parts being disposed on each side of the head, the two pairs extending toward the periphery in diametrically opposite directions, the sum of the thickness ofthe two pairs of j an -like parts being as great as the thickness of the head, the metal of the head being shaped to provide nut-receiving faces between the inner ends of the two jaw-like parts of each pair, the said nut-receiving faces of one pair being so related to the nutreceiving faces of the other pair as to be adapted to receive a nut or bolt-head be tween them.

In testimony whereof I afli'x my signature,
