LORING GOES, OF WORCESTER, MASSACHUSETTS.

WRENCH.

SPECIFICATION forming part of Letters Patent No. 229,673, dated il'uly 6, 1880.

Application filed May 17, 1880.

To all whom it 'may concern Be it known that l, LORING GOES, of Worcester, in the county of Worcester and State of Massachusetts, have invented certain new and useful Improvements in Wrenches; and I declare the following to be a description of my said invention sufficiently full, clear, and exact to enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification, and in which- Figure 1 represents a front view oi' a screwwrench constructed in accordance with my invention. Fig. 2 represents a side view ofthe same, one side of the handle being removed to show the internal construction. Fig. 3 is a perspective view oi' the bar, shank, and key. Fig. 4 is a transverse section at line rw w. Fig. 5 is a transverse section at line was. Fig. Gis a transverse section at line y y, and Fig. 7 is a section of the handle-frame only at line no an. Fig.8 is a section of the handle-frame only at the line z z.

This invention relates to that class of wrenches known as the Goes screw-wrench 5 and it consists in certain improvements in the construction of the handle and bar-shank and the method of combining and attaching said parts together, as hereinafter explained.

In the drawings, A denotes the wrench-bar,

n provided with a head, B, and supporting the sliding jaw C, operated by the rosette-screw D, in ordinary well-known manner, and therefore requiring no further description herein.

The shank of the bar ismade, as shown in Fig. 3, with a reduced portion A', about onethird (more or less) of the thickness of the iull bar, flat upon the sides, and having its edges a, which are longitudinally parallel, or nearly so, milled off on the are of a circle, or of cy- -lindrical form, the milled portion being also extended onto the thick part of the bar, as at c, for a short distance, forming shoulders d d at the front and rear sides, against which the end of the handle abuts. A central longitudiy nal slot or opening, f, is formed through the shank, as shown.

The handle is made with a metal central frame, E, to which are fitted wood side plates, F, the parts being constructed and arranged (No model.)

as follows: The upper and lower ends of the metal frame E are made the full size or thickness required for the handle, while the intermediate portion is made thinner, and of about the same thickness as the reduced part of the bar-shank, the central portion being open to receive said bar-shank and to lighten the weight oi' metal. The upper end of the frame E is made square to t against the shoulders d d ot' the bar A, and has the usual projection Gr to support the end of the rosette-screw D.

Cross plates or bars H are rigidly fixed upon the frame E, preferably cast integral therewith, and joining its two sides, e e, in the manner shown, and the said sides c c are formed concave on their inner faces to iit closely to the rounded edges of the bar-shank A th roughout the length ot' the latter. These inner edges 'are iinished by driving a breaching-tool in at the upper end and down to the enlargement at the center of the handle-frame. They are thus made to tit accurately and iirmly to the i milled edges a on the bar-shank A".

A Wedge pin or key, I, is driven through the opening fot' the bar-shank at the back of the cross-pieces H, which key I draws the shoulders d iirmly against the end ofthe handle and locksthe parts securely in place, so that the bar Aand handle-frameE are as firm and. rigid in their connection as it' solid or made in a single piece.

The key-seat i 011 the cross-bars H is milled out after the top end ot' the handle-frame is squared oft", so that the distance will be uniform on all handles, and the end seats, m,- for the wood side plates, F, may be dressed out with a circular milling-tool, so that all will be alike. The wood side pieces, F, which may be turned in pairs on a pattern-lathe and then separated, are fitted to the sides of the metal frame E, and are retained in position by the screws or rivets K, extending through from side to side, as shown, one passing through the opening f of the bar and the other through a hole in the cross-brace of the frame, as illustrated. The exterior ofthe handle is finished smooth and of an oval form at its ends, so as to project but little on the sides at its junction with the bar A, the central portion being nearly round.

The key I may be made with rounded or IOO square bearing-sides, as preferred, and could be arranged through instead of at the back of the cross-pieces H, if desired.

By constructing' and arranging the parts in the mannershown and described, a very stron g, serviceable, and desirable wrench is produced,

which can be manufactured with facility andl at a moderate cost.

What I claim as of my invention, and desire to secure by Letters Patent, is

l. The handle-frame E, provided with crosspieces H and chise-litting concaved sides e c, in combination with the bar A, having' thereduced shank A', with rounded edges a a, shoulders b, and opening f, and the locking-key I, arranged as set forth.

2. The combination, with the bar A, of the within-described handle, composed of the me tallicceutral frame, E, having close-fitted sides e o, with cross-bars H, secured to the bar-shank by the locking-key 1, 'and the wood side plates, F, fitted to said frame for inclosing said key, and secured by the circular end seats, m, and screws K, as shown and described.

Witness my hand this 13th day D. 1880.
