T all whom it may concern.'

Be it known that I, `WILLIAM H. HURLEY, citizen of the United States, residing at New Haven, in the county Of'N ew Haven and State of Connecticut, have invented `certain new 'and useful Improvements in Knife Handles; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable Vothers skilled in the art to which it appertainsto make and use the same.

This invention relates to table cutlery,

being to cheapenthe `knife construction by avoiding many of the expensive 'operations incidental to forged knives wherein the blade and handle lare of integral construc-l tion.

The improved construction consists in employing a metal tube to form the handle' and securing the same to the tang of a tem'- pered steel blade. A tube of wood,or other like lion-metallic material smaller in diameter than the interior of the metal tube, isl

inserted therein and said wooden tube and intervening space filled with lead or other like moltenmetal, and shape the metal tube to form the handle, neck, bolster and rim.

Referring to the accompanying drawings,

wherein the same figures and letters `of reference indicate like parts throughout the several views:

Figure 1 represents a broken blade; Figure 2 is a sectional view of the metal tube or shell, broken view of the blade with its tang inserted in the tubular handle, also a view of the wooden tube or core within the metal tube;

Figure 3 is an end view of Figure 2 looking in the direction of arrow ai;

Figure 4 is an end view of the metal tube and sectional view of the blade on line 4 4 of Figure 2;

Figure 5 is a sectional view of the tubular handle, wood core and lead filler, broken edge view of the blade and insertable plugs in the blade end of the tubular handle;

Figure 6 is an enlarged broken edge view of the blade, enlarged broken sectional view of the tubular handleshaped to form the neck, bolster and rim, and sectional view of the wooden tube and filling material;

Figure 7 is an enlarged broken side elevation of the blade, enlarged broken sectional view of the handle and iilling material, and

an enlarged broken view of the wooden tube embracing a part of the tang of the blade;

Figure 11 isa detail view of the wooden i tube or core.

The blade 1` is provided ywith a tang wherein the part V2 is preferably slightly and particularly to knife handles, its Object Vthetube firmly abutting against the shoulders 4; and the ends of the ellipse on a line with the front and rear edges a, b, of the blade. t 1

After the blade is firmly seated inYV the instal tube, the hollow wooden tube 6, Figure 11, is inserted in theopposite end of the metal tube with itskerf 7 embracing, Figure 2, a portion' of the tang of the blade, and it is thus held in a central position with respect to the interior of the metal tube.

The lower end ofthe tube 5 is partially closed as shown in Figure 5, andthe metal plugs Sfare inserted a short distance within the metal tube and are shaped tO fill its elliptical mouth 9, Figure 4, on each side of4 the blade, as shown in Figure 5;

Molten lead 10, or other like molten metal. is then poured into the opposite end of the metal tube, passing through the central hole 1l of the wooden tube, and about said tube, filling the space within the metal tube to the plugs 8, leaving, however, a small vacant space 0 at the opposite end for the purpose to be hereinafter more fully explained. Y

As soon as the molten metal has cooled,

- the plugs 8 are removed and the metal tube in the direction of arrow d to forni the neck Y l5 will forcethe metal filling 10 well .into

the rim 14, and also compress the lips 15vt under which there no filling material,

firmly agaiiistthe lsides of the blade zand so reduced by compression as to give the iinpresion that the blade and neck are inte- ;gm-

yIn forming the bolster 13, sthe side pressure of the die Will force the metallic filling Well into the groove 16 of the tanlQFi'gu-re 7, and thus lock the Ablade firmly tothe handle. Y

Ifthe-inetail tube Was 'entirely .filled withV lead er other like lmolten metal, .it wouldV not ,readily `compress to perniit 4the -zouter nietal shell or tube assuming the proper elliptic,

shape .required for -the .ffinished fhandle, but

would be forced kcut of the open end of the tube and ithus Vinterfere with the closing of said end. To overconie tlris, .the .compressible wooden .tube lis introduced to vconiipensate for the noii-conipressibility off `the met-al filler. In apply-ing the :necessary pressure 'to give the .elliptic shape to ithe handle, the several elements will naturally lassume fthe 'appearance shown in `Figure 10. The -ap- :plied pressure ef thedie will force the metal -iillin-g Within the Wooden `tube `outin quantity sufficient it@ fill the space c, Figure -5,

and 'not interfere with the, closing of that end .ofthe handle. Under this pressure, the :niet-al filler Will also -be forced out ofthe opposite end of this avooden -tube -to .fi-ll any vacant space occurring about `Athe ftang of rthe blade, and also lillthe hole 17 of the `-tavnk and Athus vadd an vadditional docking grip V'for the blade.

A knife, :constructed `-a-s above described, has, .when finished, 4theappearance of being forged. One of the principal features lthat give this .resemblance is, that, .like a forged knife, .the l:edges e, h, of the bladeare on a line with the elliptical ends oif the handle, which is due -to shoulders 4L of the blade, Whose'ldepth is practically equalto the thickness cf the inetail shell, so that, when the knife is finished, the edges of thebladenear the handle are on a line therewith. 1' Thus,

2. A knife vof lthe character described,

:comprising La blade fhaving .a shouldered tang, .a metal tube yWhose Walls equa-l the depth of .said shoulders, vsaidtang forcibly enteredinto Ythernouth of said shell to .give

said mouth an elliptic form with vits ends coinciding Ewith the .edges of the fblade,a noninetallic tubelocated Within the metal tube and of smaller diameter than the interior of 'the yinetal tube, inolten ineta'l injected into lboth tubes, and said tubes subjected to pres- .sure suitable to fornia closed .handle having a neck, rim and bolster. Y

3. AV knife of the character described,

comprising` a shouldered tang, a .metal ,tubc

having an' ellipticalniouth embracing .the .tang Whose ends abut said shoulders and .coincide with the edges of the blade, asinaller :non-metallic tube Within thedne'tal tubeand guided on ithetank, molten kmetal, injected into both tubes, :temporary means Afor closing `the elliptical mouth'of the outer tube, vand said `tubes vsubjected to pressure Asuitable to forma closed handle havinga neck, riinand bolster.

In testimony whereof -I affix inysignature.
