IMPROVEMENT IN WRENCHES.

Specification forming part of Letters Patent No. i 86,034, dated January 9, 1877; application led November 17, 1876.

To all whom it may concern:

Be it known that I, LORING GOES, ofV the city and county of Worcester, and State of Massachusetts, have invented certain new and useful Improvements in Screw-Wrenches and I declare that the following is 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 forma part of this specification, and in which- Figure 1 represents a side view of a wrench constructed in accordance with my invention. Fig. 2 represents a longitudinal central section of the handle. Fig. 3 represents a transverse section ofthe handle at line fr on Fig. 1, and Fig. 4 shows a modification in the construction.

This invention relates to that class of wrenches known as the Goes 7 screw-Wrench; and consists in certain improvements in the construction and method of attaching the handle to the bar-shank, as hereinafter explained.

In the drawings, A denotes the bar; B, the head jaw; G, the movable jaw; D, the ro sette and screw; and E the handle. The upper portion of the bar A, the jaws B G, and the rosette-screw D may be of ordinary construction, and, therefore, require no particular description.

The handle E I make from metal, cast with the proper external form, cored out at its interior, and open at the sides, as at F, leaving the metal at the parts e ein the form of thin shells or ribs of suitable curvature to be conveniently grasped by the hand.

The parts e e join at the upper and lower ends of the handle, and a transverse bar or perforated plate, El, is cast across between the parts e e, at or near a central position of the handle, and through which the rounded end of the bar-shank extends, while on the upper end of the handle is cast the projection or step E2, in which the end of the rosettescrew D is supported, thus making the entire handle and step in a single piece.

The shank A' of the bar A I make quite short, about one-half the length of the handle, more or less. The shank A' is worked o to form shoulders at a a, which closely tit the opening at the upper end ot' the handle, while the lower end of said shank is tapered to pass through and lit the opening in the plate E'. A nut, H, is screwed onto the end of the shank A', and against the cross-plate El, Which draws the handle firmly against the shoulders a a, and retains the parts securely in position.

The handle E and step E2 being made from metal in a single piece, there is no chance for any looseness, splitting, or wear, as is very liable to occur With the ordinary wooden handles; neither is there any possibility of the handle turning independent of the bar, While all back strain from the jaw G, through the rosette-screw D, is transferred to and borne by the bar A and nut H. The nut H being i11- closed Within the handle E is not liable to become loosened by the rough usage to which the wrench is subjected.

The portion ofthe handle E above the nut seat or plate E', may, if desired, be made solid, as shown in Fig. 4, but I prefer the form shown in Figs. l and 2.

By reducing the length of the bar-shank A', and the number ot' parts in the wrench, I et'- t'ect much saving in the cost ot' production, without detracting from the efficiency or durability of the Wrenches.

What I claim as new, and ot' my invention, and desire to secure by Letters Patent, is-

1. The metal handle E, having the step E2 and nut-seat or cross-plate El, in combination With the bar A A', rosette-screw D, and nut H, substantially as shown and described.

2. In combination with the bar A, having ashort shank, A', and shoulders a a, the metal handle E, made with thin shell or ribs e e, and secured to said bar by a separate nut, H, screwed on the end of said shank A', Within the central part or interior of said handle, substantially as set forth.

LORING GOES.
