SPECIFICATION forming part of Letters Iatent No. 543,925, dated August 6, 1895.

Application filed January 9, 1895.. Serial No. 534,334. (No model.)

To all whom it may concern:

Be it known that I, FREDERICK L; Cons, 'a citizen of the United States, residing at Worcester, in the county of Worcester and State of Massachusetts, have invented anew and useful Improvement in Wrenches, of which the following, together with the accompanying drawings, is a specification sufficiently full, clear, and exact to enable per- 1: sons skilled in the art to which this invention'appertains to make and use the same.

This invention relates to the peculiar construction and manner of combining the Wrench-bar and handle by means of trans- 5 versely-disposedinterlocking keys introduced and upset into opposite recesses or grooves formed across the sides of the wrench-bar and within the body of the ferrule, as more fully hereinafter explained, the object of my invention being to afford a simple, inexpensive, and rigidly strong construction in a wrench or tool of the class, as specified.

In the drawings, Figure 1 is a side view of a wrench embodying my invention. is a transverse section at line W W. Fig. 3 is a transverse section at line Y Y. Fig. 4 is a longitudinal section at line X X. Fig. 5 is a side view of the bar-shank, and Fig. 6 shows the form of the interlocking key.

. Referring to parts, A denotes the Wrench- .bar; A, the fixed jaw; B, the movable jaw; C, the rosette screw; D, the ferrule; E, the wood handle, and F the tip or end piece.

According to my present invention the bar- 3 5 shank A is made with that portion whichis within the ferrule formed with fiat parallel sides a and rounded front and rear edges a below the shoulder h. A groove G is cut or formed in the fiat side a of the bar-shank, extending transversely across the same, and prescnting a square shoulder i at-its lowerlimit. The interior opening through the ferrule D is shaped to fit the flat sides and rounded edges of the shank. A transverse groove cl is formed in the inner surface of the ferrule,

tend as rectangular openings through thebody of the ferrule at positions somewhat be- Fig. 2

low the rosette-steps D or as indicated at m.

The grooves in the bar-shank are preferably made somewhat Wider than the grooves in the ferrule, as shown.

When the parts are assembled, a rectangu lar key K, the width of which corresponds with the width of the groove in the ferrule and of a thickness equal to the depth of the grooves in both the ferrule and bar-shank 6e and of sufficient length to reach through the ferrule, is introduced or driven into the opening m and grooves cl and G, which key, seating on the shoulders t', n, and i, interlocks with both the bar-shank'and ferrule and holds the ferrule securely in place upon the bar-shank with its end firmly against the shoulder h. The key. is upsetand wedged firmly within the groove-space and against the shoulders i, t", and it by riveting down its ends m, which ends are subsequently dressed off flush and smooth with the exterior surface of the ferrule, thus producing a solid and finished connection for the parts.

The wood hand piece E, which is best formed in a single piece, has a longitudinal opening 0, oblong in cross-section, extending therethrough for receiving the bar-shank, the respective ends of the hand-piece being reduced and inserted beneath the lips e e formed on the ferrule D and tip F, as shown, and the tip being arranged upon the reduced end a of the shank, which latter is riveted into the opening of the tip atf in well-known manner. 8

I claim and desire to secure by Letters Patent 1. The wrench-bar-shank having the transverse groove formed in the flat side thereof, with a square seating shoulder at the lower limit of said groove; in combination, with the ferrule having an opposite internal transverse groove, of less width, with seating shoulders at its upper and'lower limit, and openings at the ends of such groove through the body of 5 the ferrule, and the angular interlocking-key fitting the width of said ferrule groove, upset within the opposite grooves and against the lower seating shoulders of both the bar-shank and ferrule, for the purpose set forth.

2. The wrench-handle composed of the ferrule, its interior fitting upon the bar-shank,

and having transverse internal grooves and bar-shank, said keys upset within the groove shoulders with openings at the ends of said spaces firmly against the shoulders, their ends grooves through the body of the ferrule, the riveted and dressed off flush with the cxter 5 end-tip attached to the shank end and the rior surface of the ferrule, substantially as 5 hand piece having a transversely oblong openset forth.

inglongitudinally therethrough, and reduced Witness my hand this 3d day of January, ends engaged by the tip of the ferrule; in 1895. combination with the bar-shank having transw 1 versely disposed grooves and shoulders in its BREDERKK GOES [0 sides, opposite those in the ferrule, and the Witnesses:

rectangular keys inserted within said grooves CHAS. H. BURLEIGH,

and interlocking with both the ferrule and ELLA P. BLENUs.
