HARRY JEFFREY, OF LOUISVILLE, KENTUCKY, ASSIGNOR TO THE OHIO MALLEABLE IRON COMPANY, OF COLUMBUS, OHIO, A CORPORATION OF OHIO.v

WRENCH.

Specification of Letters Patent.

Patented March 30,1909.

Application filed may 21, 1908. Serial No. &%,186.

To all whom 'izfomy concern:

Be it known that I, HARRY JEFFREY, a

citizen of the United States, residing at Louisville, in the county of Jefferson and State of Kentucky, have invented certain new and useful Improvements in Wrenches,

of which the following is a specification,

while in position of engagement or trans-.

versely of the axis, and which. shall have a continuity of metal 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 durability are secured without increasing the thickness of the metal over that used in making the ordinary open-jaw 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 a cross section on the line XX of Fig. 1; and Fig. at is an end view. 1

The wrench shown in the drawings is constructed with a shaft or handle 1, having an expansion or head Q at the end. This head is integral with the handle and has two jawlike parts 3, 3, which may be regarded as extensions of the head, proper, and are of substantially the same thickness. A cavityv is formed in the head having walls at, at, inclined to each other, and walls 5, 5, substantially parallel. This head has a groove or rabbet in the'metal extending radially outward from the cavity or aperture 8. The side walls 5*, 5 of this groove are extensions continuations of the side walls 5, 5, of the al with the jaws 3, 3, andforming the eottom of the groove. This tie web 6 is, on one side, flush with the face 9 of the head 2.

6 is a: tie web formed in-' plied to a nut or bolt-head in the way a socket is ordinarily applied; that is to say, by moving the head 2 along lines parallel to the axis of the nut or bolt until the walls 4, 4, 5,5, 7, 7, of the cavity or aperture 8 engage with the sides of the nut. Or it can be connected with a nut or bolt in the way in which a spanner wrench is manipulated,

this being done in places Where the nut or bolt-head is in a contracted space with some object near the outer end of the nut or bolt to compel the moving of the wrench into the position of engagement by sliding it on lines transverse to the axis of the nut. In such case the head 2 of the wrench is so will 'be seen that a wrench constructed with the parts above described canbe applaced in relation to the nut or bolt-head that the wrench head can he slipped transversely along thenut until the'lattercomes to the aperture 8 whereupon it can be pushed parallel to the axis to get firm engagement.

I do not herein claim broadly the inven-. tion in wrenches shown and described in this application, such claims having been presented inv my application No. 438,439, for the reissue of Patent No. 873,437.

What I claim is:

1. A wrench for nuts and bolt-heads c0mprising a' handle or shank 1 having a head 2 cast integral with the handle the head having a" nut-receiving aperture extending through the head and formed with. two jawlike parts 3, 3, extending parallel to the longitudinal lines of the handle and having inner faces coincident with opposite faces of the nut-receiving aperture, the said aw-like parts having formed integral therewith a tie-Web or plate 6, having its outer face substant'ially continuous at each end with one of the faces of the head, said jaws being adapted to slide along the sides of a nut or bolt-head,.and the web to slide over the end thereof, substantially as set forth.

2. A wrench for nuts and bolt-heads, comprising a handlezor shank 1, having a head 2 integral-therewith, and said head having a non-circular nut-receiving opening and of theslide faces of'the head, and adfipteki: Witnesses:

two integral jaw-like parts '3 having inner I lezigth than the Width of the said jaw-like faces alihing flush with opposite faces of the parts, substantially as set forth. 10' said aperture: and a- Web or tie-plate Gin- In testimony whereof I afiix my signature, tegraiwith the jaws, the Web being. subin presence of two Witnesses; i v v stantially continuous at each end with one HARRY JEFFREY.

to slide over-the end of a nut, or b01t-head, v FRED H. HEYWDOD, the nut-receiving aperture being of greater F. F. HAEFFLE.
