UNITED STATES PATENT OFFICE.-
FREDE ICK SEARLE, F WORCESTER, MASSACHUSETTS, ASSIGNOR To LORING COES & COMPANY, INCORPORATED, OF WORCESTER, MAS- SACHU ETTS, A CORPORATION OF MASSACHUSETTS.
CONSTRUCTION OF WRENCH-HANDLES.
SPECIFICATION forming part of Letters Patent No. 6 dated December 1901- I Application filed October 28, 1901. Serial No. 80,173. No model.)
State of Massachusetts, have invented anewand useful Improvementin the Construction of Wrench-Handles, of which the following, together with the accompanying drawings, is a specification snfficiently full, clear, and exact to enable persons skilled in the art to which; this invention appertains to make and use the same. p Y
My present invention relates to an im proved structure of the wrench-handle and manner of its combination with the wrench-bar shank, the objects being to provide an efficient, light, and durable all metal handle for screwwrenches, more especially for wrenches of large size, which handle will have a firm and strong connection with the wrench-bar and will withstand rough usage and usage in water or in wet situations without detriment, also to afford a construction and combination that will admit of the wrenches being manufactured with practical economy. For the attainment of these objects my invention conslsts in the wrench-handle mechanism constructed as hereinafter explained, and illustrated in the accompanying drawings, in which- Figure 1 represents a Side view of a wrench embodying my improvement, a portion of the handle being shown as broken away to reveal the internal structure. Figs. 2 and 3 represent longitudinal sections of the handle at lines V V and T T, respectively, on Fig. 4:.
Fig. 4 is a top end viewof the handle. Figs. 5 and 6 represent transverse sections of the handle-piece at lines W W and X X, respectively; and Fig. 7 represents a transverse section of the handle, bar-shank, and keypin at the position of line Y Y.
Referring to the drawings, the part marked A represents the wrench-bar, carrying the.
fixed jaw A and having the partially-rounded neck, with handle-positioning shoulders at d, and the laterally-reduced bar-shank A having the flattened broad sides 3, the slightlyrounded front and rear edges e e, and terminating at its end with a flattened tang or rivetable end 5.
B indicates the movable jaw, slidingon the bar A in well-known manner, and O the jawadjusting screw, having the thumb-rosette O for operating the said jaw in usual manner.
D indicates the handle, which according to the hand to conveniently grasp, its internal form corresponding in general to the external form, but provided with bearing-surfaces and other internal features, as hereinafter explained'. At its upper end the handle is formed as a collar portion D, squared off at the end 6 and having the projection 7, that serves as a step bearing or support for the end of the rosette-screw O. The collar portion has an interior opening, with bearingsurfaces 8, of the proper shape to closely fit the neck of the bar-shank when the end 6 is against the shoulders (1. At its lower end D the handle is provided with a longitudinal dovetailed Opening 9 for receiving the tang 5 of the bar-shank.
The shell 4 is provided internally at front and rear with integral inwardly-projecting longitudinal ribs 12, the inner edge faces 6 and e of which are disposed in continuation of the neck-opening'surfaces S, aifording an approximately parallel width of space between the ribs for' the reception and support "of the bar-shank, said ribs being approximately the same thickness as the bar-shank. Formed integral upon the shell 4, at positions intermediate to its bearing ends, Iprovide opposite inwardly-projecting brace lugs or fins 13 and key-supporting bosses 15, which reach inward from the shell sufficiently far to impinge or seat at their inner ends against the fiat sides 3 of the bar-shank A The bracelugs 13 are preferably made as longitudinally oblong thin projections having narrow bear ing-surfaces at their ends, and the ribs 12, brace-lugs 13, and bosses 15 are formed within the handle-casting with such projection that their faces can be dressed ofi by means of a suitable broaching-tool forced into the handle through the neck-opening, thereby forming accurate bearing-surfaces on said lugs, ribs, and bosses for receiving and fitting against the wrench-bar shank and giving a firm and rigid support of the handle thereon.
\Vhen the parts of the wrench are assembled, the collar end of the handle is forced solidly against the positioning-shoulders d and closely embraces the neck of the bar, while the tang 5 or small end of the shank is firmly upset and riveted into the dovetailed opening 9 in the lower end of the handle, thus forming water-tight joints at both ends of the handle and.closing the interior hollow from external influence. A pin or key]? is driven laterally through the handle and bar-shank, passing through an opening 16 within the bosses 15, and riveted at its ends flush with the exterior surface of the handle, thereby clamping the opposite bosses and brace-lugs l3 solidly against the flat sides of the barshank. The edges of the inwardly-projecting ribs 12 take firm bearing against the edges 6 e of the bar-shank A when the latter is inserted or driven into the handle, While the brace-lugs 13 and bosses 15 take firm bearing upon the sides of the bar-shank and prevent liability of the shell 4 being indented or crushed in laterally, even when made comparatively thin. The upsetting of the tang 5 into the dovetailed opening 9 rigidly secures the parts together.
Since metal handles of different construction have heretofore been employed in wrenches, it will be understood that I do not herein broadly claim a metal handle for wrenches irrespective of the construction thereof; but my invention has reference to the specific construction and combination of the character defined.
What I claim as of my invention, and desire to secure by Letters Patent, is
1. A handle for wrenches, comprising a hollow handle-form or metal shell having openings adapted to fit upon the wrench-bar shank, said shell provided with inwardly-projecting integral longitudinal ribs, the inner faces of which are adapted for support against the edges of the wrench-bar shank, substantially as set forth.
2. The within-described wrench-handle, consisting of a hollow metal shell of complete handle form, provided at one end with the screw-step projection and neck-fitting opening, and at its other end with a tang-receiving opening, said shell provided internally with longitudinal inwardly-projecting barsupporting ribs, at front and rear, and having upon its interior sides integral, inwardly-projecting brace-lugs, and key-supporting bosses, substantially as and forthe purposes set forth.
3. The combination, with the wrench-bar having the handle-positioning shoulders, reduced neck,and laterally-flattened bar-shank; of an all-metal handle-piece consisting of a hollow shell externally of the handle shape, one end thereof fitting the neck of the barshank against said shoulders, and the other end fitting the tang end of the bar-shank, said handle-shell being internally provided with integral inwardly-projecting ribs that seat against the edges of the bar-shank, the inwardly-projecting fins or brace-lugs that impinge laterally against the fiat sides of said bar shank, the opposite key supporting bosses, and a key-pin passing through said bosses and bar-shank, substantially as set forth.
Witness my hand this 26th day of October, 1901.
FREDERICK SEARLE.
