KNIFE-BOLSTER.

TPECIFECATON forming part of Letters Patent No. 336,107, dated February 16, 1886.

Application tiled October 9. 1885.

To @ZZ whom, t may concern.-

Be it known that I, GEORGE HAvnLL, a citizen of the United States, residing in Newark, Essex county, New Jersey, have invented certain new and useful Improvements' in Knife-Bolsters,fully described and represented in the following specification and the acco1npanying drawings, forming a part ofthe saine.

The object of this invention is to combine a sheet-metal blade and tang with a solid knifehandle; and i-n order to properly bolster the blade at the point where the neck of the tang projects from the handle I have devised a sheet-metal bolster of peculiar construction, and ani thereby enabled to form the entire metal-work of the knife of sheet metal, so that it may be produced with the ordinary stamping`-tools employed in making sheet metal.

The nature of my improvements will be understood by reference to the annexed drawplete knife constructed with my combined bolster and ferrule. Fig. 2 is a side View of a knife provided with the bolster only, the handle and bolster being shown in section to exhibit the fitting of the bolster to the neck ofthe blade. Fig. 3 is a plan of the bolster; Fig. 4, a side View of the same. Fig. 5 is a Vertical section of the bolster shown in Fig. 4, as on line z z in said ligure; Fig. 6, a vertical section of a combined bolster and ferrule, taken longitudinally, as on line rv x in Fig. 3, a slotted collar being secured wit-hin the ferrule to brace the tang of the knife, which is indicated by dotted lines therein; and Fig. 7 is a plan of such collar before its insertion in the ferrule.

Fig. l shows the application ofthe conibined bolster and ferrule to a knife with a solid handle.

a is the knife-blade; b, a narrow tang adapted for insertion within the handle d, and c is the neck of the knife, formed wider than the tang, and provided with shoulders to rest upon the ends of the bolster.

e is a flange formed within the bolster to bear upon the end of the handle.

f is the ferrule, and g is the guide, formed apart from the ferrule, and secured within the 'metal as thev other parts.

eombined with the sive) may be used apart frointhc ferrule, and

is constructed by forming the opposite halves `(as upon each side of the line .fr x in Figf) from a sheet metal blank of suitable shape stamped to the required form by means of a punch and die, (as is common in sheet-metal manufacture,) and finally united together at their joint by soft or hard solder. The outer end of the bolster is slotted to receive the neck c, as shown in Fig. 2, and fitted to the shoulder c upon the neck of the blade, so as to brace the blade edgewisc, and the throat of l the bolster is fitted, as at c" in Figs. 3 and ings, in which Figure lis aside view of a comto fit closely upon the Hat sides of the blade and brace it laterally. The handle being properly secured to the tang, with its open end in contact with the flange e, the bolster is perfectly stayed upon the blade, and imparts to its neck nearly the same stiffness as if it were integral therewith.

To ornament the knife, and to impart additional stiffness to the bolster, I sometimes construct it with an attached ferrule, as shown in Figs. l and 6, the opposite longitudinal halves (as at either side of the line :v :c in Fig. 3) being formed in a single piece, and when the two are united by solder upon their vertical joint they form a combined bolster and ferrule, as shown in Figs. l and 7.

The slot c2 is formed in the outer end ofthe bolster to iit the neck of the blade; but the guide g for'thetang must be situated within the body of the ferrule, (to permit the insertion of the handle in the latten) and cannot therefore be stamped from the same piece of Such guide is therefore formed by stamping it from sheet metal separately with its exterior h't-ted to theinside of the ferrule, and its center formed with a slot, g', to fit the tang b, as shown in Fig. 7. The bolster and ferrule being preferably united by a contracted neck, as atl in Fig. l, the

IDO

guide may be placed within the ferrule in contact with such neck, and Without fastening therein would serve to guide and steady the tang effectually when the ferrule is secured upon the handle and the tang cenientedin the blade.

I am aware that it is not entirely new to stamp a knife bolster from sheet metal, as such a construction is shown in German Patent No. 18,528, of 1881; and I ain also aware that cast-metal bolsters of form analogous to mine have already been used, as in United States Patent No. 277,932, of 1883. I therefore disclaim the said patents and any con` struction different from that specifically claimed herein.

The method of manufacturewnaniely, the use of sheet metal for both the bolster and the blade-enables me to dispense with the labor of forging or casting any of the parts, and to secure an article practically equal in strength and beauty to those produced by a more expensive and tedious process.

Having thus described the nature and objects of my invention, what I claim is* The combined knife bolster and ferrule formed of sheet metal, in two parts, solderedl GEORGE HAVELL.
