TABLE CUTLEBY.

Application Med July 3,

This invention relates to table cutlery and particular-l to blades having non-metallic handles. lii this kind of cutlery, especially where the handle is of hard rubber, the hana dle will expand and soften in hot water and loosen the blade and cause it to drop from the handle. The object of the present invention is to provide suitable anchorage for the blade that will maintain its contact with l the handle under all conditions.

Referring to the accompanying drawings wherein the same reference characters indicate like parts throughout the several views:-

Figure l represents a blade having a bolster with an integral tail-piece of fusible material mounted on the tang of the blade showing the means of anchoring the tailpiece, also broken sectional view of the handle;

Figure 2 is a detail view of the handle;

Figure 3, is a broken detail view of the blade;

Fi re 4 is a detail broken sectional view of the handle showing the bore for the tang of the blade having anchorage grooves formed about the bore;

Figure 5 is a broken view of the back of the blade with the bolster, tail-piece and anchor ribs mounted on the tang of the blade;

Figure 6 is a broken view of a two part` mold, and broken view of the blade and handle mounted therein;

Figure 7 is a broken plan view of the closed mold;

Figure 8 is a broken view of the back of the blade showing a modification of the anchorage, and

Figure 9 is a broken view partly 1n section of the handle and broken view of the blade with its tang inserted in the bore of the handle.

The usual construction of this type of cutlery, so far as known, consists of the blade l having the tang 2 about which is molded the bolster 3 having the tail piece 4, of fusible material. The bore 5, Figure 4, is formed in the handle 6 of the proposed size for the tail piece. Theindentation 7 is for the reception of the end of the blade tang projecting beyond the fusible metal construction. It will readily be seen that when the rubber handle is brought in contact with hot water, it will both soften and 1926. Seal No. 190,858.

expand and lose its holding grip on the tail piece of the bolster.

To overcome this trouble, a properly shaped tool, not shown, is inserted in the bore 5, Figure 4, to form the circumferential grooves 8, see also Figure 2, larger than the bore 5. The tang 2 of the blade is then inserted in the bore of the handle 6, and said handle enclosed in the conventional twopart mold 9, Figure 6. This mold has the opening A10 through which fusible metal is admitted to form the bolster 3, its tail piece 4 and the ribs 11, which ribs, filling the lateral branches or grooves 8, will, when the metal hasl cooled, form a perfect anchorage to prevent accidental withdrawal of said tail piece 4 from the handle, while the projections 12 of the tang, embedded as tney are in the bolster, will prevent withdrawal of the tang 2 from the fusible metal plug, com rising the bolster 3 and the tail piece 4. he recess 13, Figure 7, in the mold is for the reception of the inner end of the blade.

The gist of the invention consists in providing means whereby the conventional plug of fusible metal having a bolster and tail piece, is anchored in the handle. As before mentioned, this consists in providing one or more indentations or recesses extending laterally from the bore in the handle to be filled with the same fusible metal comrising the bolster and its tail piece and to orm an integral part of the latter.

It is readily conceivable that various shapes of these lateral branches leading from the bore of the handle to form suiiicient anchorage could be adopted, but one or more openings must be employed to accomplish the purpose required.

In Figure 8 is seen a modification of this anchorage feature, comprising the V-shaped enlargement 14 forming an integral part of the tail piece 4, which enlargement was produced by a similar shaped lateral branch of 100 the bore of the handle, not shown.

Having thus described my invention what I claim is 1. The hereindescribed method of attaching cutlery blades having tangs to handles, 106 which resides in forming a, bore of relatively short length having closed sides and a bottom in the end of the handle to receive the tang, said bore having a portion of greater diameter than the tang and having lateral 110 recesses opening thereinto, then in inserting the tang in the bore and enclosing the adjacent parts of the blade and handle in a mold, whichl latter has bolster molding faces, and finally in introducing fusible metal in the mold to lill the spaces between the bore and tang and the recesses, and to simultaneously fill said bolster molding faces, thereby to connect the tang to the handle and to form said bolster without eX- posure of the part of the filler Within the handle.

2. In combination with a cutlery blade having a tang. a handle having a tang-receiving bore formed in one end thereof, said bore being of relatively short length and having closed sides and a bottom, the lower part of the bore being of a size to frictionally engage and center the tang in the bore and the upper part of the bore being of greater diameter than the Width of the tang and having lateral recesses opening thereinto, and a metal filler in the bore completely) filling the recesses and spaces unoccupied y the tang and extending above the said end of the handle and enclosing the adjacent part of the tang so as to form a bolster and to simultaneously anchor the blade to the handle without exposure of the part of the filler Within the handle.

3. In combination with a cutlery blade having a tang, a handle'having a tang-receiving bore formed in one end thereof, said bore being of relatively short length and having closed sides and a bottom, and hav. ing lateral recesses opening thereinto, and a metal filler in the bore completel filling the recesses and spaces unoccupied y the tang and extending above the said end of the handle and enclosing the adjacent part of the tang so as to form a bolster and to simultaneously anchor the bladeto the handle Without exposure of the part of the filler within the handle.

In testimony whereof I affix my signature.
