HOLLOW-HANDLE ARTICLE.

,epplication filed February 4:, 1924. Serial No. 690,353.

To all it may concern:

Be it lmolwn that L'Bnnrn J. MARSH, a citizen of the United States. residing at Wallingford, in the county of New Haven and State of Connecticut, have invented a new and useful Improvement in Hollow- Handle Articles; and I do hereby declare the following, when taken in connection with the a certainin raw a d e characters er reference marked thereon, .to be a full, clear, and exact description of the same, and which "said drawin'gsconstitute part of this application, and represent in Fig. 1 a view in cleya tiqn of a tableknife embodying my inyention.

Fig. 2- a similar view with the hollow handle in fiatwise section.

Fig. 3 an edge view with the handle in edgewise section.

Fig. 4 a view of the blade and bolster in position for the tang of the former to be inserted into the handle, which isshown partly in elevation and partly in edgewise section.

Fig. 5 a view in transverse section of the handle on the line 5-5 of Fig. 1.

Fig. 6 a detached plan view of the independent bolster.

My invention relates to an improvement in hollow-handle articles, particularly table knives and forks, but capable of use in the manufacture of a variety of kindred articles in which an implement is mounted in a hollow handle, the object being to greatly re duce the cost of labor and material entering into such articles without any impairment in the appearance thereof.

With these ends in view, my invention cOI1- sists in hollow handle articles characterized by a one-piece, struck-up. sheet-metal bolster having its edge shaped to be interlocked with the corresponding edge of the mouth of a hollow handle.

My invention further consists in a hollowhandle article having certain details of con struction as will be hereinafter described and particularly pointed out in the claim. For the illustration of my invention, I have shown it as applied to tabl knives for which it was primarily designed and for which it is peculiarly adapted, though I do not limit myself to such use of it, as already stated.

As herein shown, the blade 10 and tang 11 of the knife are cutout from a single piece of wrought sheet-metal of suitable gauge, instead of being forged from a rod, which is th customary practice inthe manufacture of hollow-handle table knives. Upon the said bladel mount a one-piece struck-up, sheetmetal bolster 12, the apex of which is formed with a longitudinal slot 1-3 adapted in length and width to receive the inner end or butt 14 of the tang 11, at the point where the same merges the blade 10 proper. The open end of the said bolster formed with a con tinuous flange 15, the edge of which is sleeved over and turned into a circumferential locking-groove l6 encircling the mouth of hehcll w han l 11 whiell may as any approved construction and design, the said groove 16 being flanked its inner side by a bead or fillet 18. The locking-fiange 15 may be turned into the said groove in any convenient manner, such as peening, rolling or by dies.

After the tang 11 of the blade 10 has been passed through the assembling-slot 13 of the bolster 12, the bolster is preferably secured to the tang, and hence to the blade, by a small mass of solder 19, located within it, as shown in Fig. 4, whereby the bolster is secured to the blade and whereby the bolster-opening 13 is closed so as to prevent the access of any moisture into the handle.

Preferably, though this is not necessary, the handle is filled with some suitable composition, such as 20, surrounding the tang 11 and filling the handle and, as shown, the bolster, whereby the tang is imbedded in the composition and prevented from flatwise deflection within the handle, in case of flatwise pressure upon either face of the blade. To further anchor the tang and hence the blade in place, the tang, as shown, and preferably is formed with anchoring-notches 21 receiving portions of the composition, whereby the tang and hence the blade are more firmly held against longitudinal displacement.

Instead of filling the handle with composition 20, as shown, I may adopt the common and well-known practice of inserting a cartridge, so to speak, of fusible metal into the handle prior to the application thereto of the blade and bolster; then, after the same have been assembled, the knife is reversed in position and thehandle heated, causing the fusible metal to fuse and re-form itself around the tang, so as to form a solid anchoring mass therefor. This expedient is too well known in the art to call for illustration.

Heretofore, hollow-handle table-ware has generally been produced by forging the imn. plement-memben such as a knife-blade,

1 terial, by making the same of heavy sheetmetal stock, being enabled to do this by the employment of an independently-forn1ed struck-up one-piece bolster which presents not only an elegant appearance but constitutes an efiective joint between the implement-member and the handle of the article, the adjacent edges of the said bolster and handle being shaped to be interlocked.

I claim:

The combination with a hollow, sheetmetal handle of unbroken external contour between its ends and of the full length of such handles, and having a locking-groove formed close to its open inner end, of a short, struck-up, one-piece, sheet-metal bolster having its apex slotted and having its flange adapted to fit over the edge of the open end of the handle, and to be turned into the said locking-groove adjacent thereto,

whereby the bolster and. handle are interlocked at the inner end oil? the latter, an implement having a tang passing through the slot in the apex of the bolster and into the handle, and a body of filling material located within the handle and embedding the said tang for giving stability to the implement.

In testimony whereof, I have signed this specification in the presence of two subscrih 111g witnesses.
