RUSSELL R. GOES, 0F WORCESTER, MASSACHUSETTS, ASSIGNOB OF'ONE-HALF TO GOES WRENCH COMPANY, OF WORCESTER, MASSACHUSETTS, A CORPORATION OF MASSA- OI-IUSETTS.

WRENCH-HANDLE.

Specification of Letters Patent.

Patented Nov. 2, 1920.

To all whom it may concern Be it known that I, RUssnLL R. Cons, a citizen of the United States, residing at Worcester, in the county of Worcester and State of Massachusetts, have invented certain new and useful Improvements in lVrench-Handles, of which the following is a specification.

My present invention relates to a novel construction in metal handles for screwwrenches, as more particularly hereinafter set forth; one object being to provide a wrench of the character described, with an all-metal handle of economic construction provided with a plurality of scallops or finger-receiving corrugations along its edge, which smoothly merge withthe non-corrugated side surfaces of the handle, the several parts being constructed and combined substantially as hereinafter more fully explained,

it. further object is to provide a wrenchhandle comprising handle frame having its longitudinal edge-embracing members integrally connected by a plurality of outstanding transversely arched braces or crosstie members at the opposite sides of the shanku'eceiving space; said frame provided with protuberances and depressions along its edge, in coinciding relation to said braces; and an exterior grip surface or shell consisting of comparatively thin wroughtmeta] tubing of uniform gage, mounted upon said frame and permanently compressed thereon, forming a plurality of prominences and intervening depressions along the edge of the handle.

These objects I attain by a wrench-handle construction. substantially as explained in the following detailed description, and illustrated in the accompanying drawings, wherein Figure 1 represents "a side view of a screw-wrench embodying my invention. Fig. 2 is a longitudinal section of the handle as assembled upon the wrench-bar shank. Fig. 3 is a side View of my improved wrenchhandle frame separate from other parts. Fig. 4 represents a cross-section of tubing such as employed for forming the exterior grip surface of the handle, Fig. 5 is a transverse section at line X X on Fig. 1.

Fig. 6 is a transverse section at line Y Y. Fig. '7 is a bottom end View of the handle, and Fig. 8 is a sectional view showing a modification in the'arrangement of the tip.

In the drawing, Fig. 1, the numeral 1 indicates the bar of the wrench and 2 the wrench-bar shank; which bar and shank are formed substantially as heretofore employed; the shank having flat sides and parallel longitudinal edges transversely rounded.

F indicates the cast-metal handle frame, which in accordance with my present invention is preferably made in the peculiar skeletonized form illustrated, and comprises the neck-supporting ferrule 3, with the usual bearing-step 4c for the jaw-adjusting screw S; front and rear longitudinal shankembracing edge-members 5, and tip-end disk (5, integrally united with the ferrule 3 by said members 5, the inner faces of which [it against the edges of the bar-shank 2 and have firm support thereon, while the ferrule embraces the neck of the bar and fits firmly up against the shoulder 11, as heretofore employed. An opening is formed in the end-disk 6 forthe reception of the reduced end 8 of the shank.

Upon the outer edge of the handle-frame, below the ferrule or screw-bearing step, I provide, along the shanlcembracing member 5, a plurality of protuberances 9 and depressions or concavities l0 the latter presenting, longitudinally, inwardly curved surfaces between the having, laterally, a convex or rounded form. The two longitudinal members 5 are integrally united at intervals across each side of the shank-receiving space by narrow transverse braces or laterally outstanding cross-ties 12 severally disposed in substantially coincident alinement with the protuberances 9 and having open intervening spaces 13 between the several. cross-ties, as best shown in'Fig. 3. The inner surfaces of the cross-ties seat flatly against the sides of the wrench-bar-shank 2, and their outer edges are rounded or arched to correspond with the cross-section shape of the handle.

The central cross-tie is preferably reinforced, as at 14, and provided witha recess protuberances and 7 15 to accommodate the key or pin 16 that is inserted through the shank for securing the handle frame thereon.

The periphery of the end-disk 6 isbest rounded or beveled off at its outer angle, with or without a slight shoulder, as 7.

The grip-face or exterior member 20 of the handle is made of a single straight section of comparatively thin wrought-metal drawn or welded tubing of uniform thickness, preferably of No. 12 gage, more or less, which may be cut to the required length; said tubing being of a caliber that will conveniently fit over the exterior contour of the handle-frame and be supported by the peripheral surfaces of the cross-ties 12, and disk 6, and the end of the ferrule 3, which latter is best reduced, as at 18, to

accommodate the thickness of the tube 7 metal.

The handle-frame F, which may be of cast metal, is formed with protuberances 9 and depressions 10* along edge, and with the transverse cross-ties 12 coinciding in their relation with the protuberances; the intervening spaces 13 relatively coinciding with the depressions 10"; the lower end 18 of the ferrule, the end-disk 6 and exterior contour of the cross-ties being of approximately similar diameter and rotundity. The interior of this handle-frame is formed or broached out to a size of opening that will closely fit upon the shank 2. After placing the sliding jaw J uponthe bar, said handleframe is assembled upon the wrench-bar shank, against the shoulder 11 and the keypin 16 driven tightly into place, said keypin being a well known form of fastener. The reduced end of the shank is also riveted at the outside of the end-disk, as at 8.

The exterior grip-face member or wroughtmetal tubing 20, of the character specified, cut to proper length, is arranged upon the exterior of the handle-frame, the upper end of said tube abutting against the ferrule, or

fitting a shoulder formed thereon, as at 18.

Said tube extends straight across the depressions 10*, but rests upon the protuberances 9 and the outer edges of the cross-ties or braces 12.

This exterior grip-face shellor tubular member 20 is compressed firmly and rigidly upon the exterior of the supporting members of the handle-frame, and portions of the tube between the protuberances 9 are sunken into the depressions 10*, thereby affording a plurality of permanent transversely disposed finger-receiving corrugations 10 and ridges 9 along the front edge of the handle, below the projecting screw-bearing step; said corrugations laterally diminishing and smoothly merging with the plain non-corrugated surface of the grip at the respective sides of the handle, as best shown in Figs. and 5. Also, the lower end of the tubular member is curled inward, as at 26, and crimped firmly against the rounded or beveled periphery of the integrally attached end-disk 6, meeting the shoulder 7, (see Figs. :2 and 7) thereby making a neat end form which can be readily finished or polished as desired. My above described invention produces a very convenient, efficient and desirable wrench construction which can be manufactured with practical facility and economy.

In some instances it may be desired to have a tip-end member separate from the handle-frame; therefore in Fig. 8 I have indicated a form of construction that may be employed therefor in that instance. The handle-frame and tubular grip with corrugated front edge is practically the same as above described, but a separate tip-piece 23 is employed and the end of the tube 20 abuts against the rim of said tip-piece, instead of being crimped in at the extremity of the disk.

1 claim as my invention and desire to secure by Letters Patent 1. A wrench handle including a skeletonized handle-frame comprising longitudinal bar-fitting edge members united by shankembracing collars at the end, and a plurality of transversely disposed outstanding cross-tie members, with intervening spaces between them; in combination with a thinmetal exterior grip-face-shell internally supported rigidly upon said outstanding members, and having portions of the shell permanently depressed or sunk into the intervening spaces upon said handle-frame, substantlally as set forth.
