y p SEGIFIOATIQN.

TO ALL WHOM IT MAY CONGERN:` i `g Be it known that I, GEORGE PARR, of the city of Buialo, county of Erie, and `State of New York,hav`e invented a new and useful Improvement in the Manufacture of Cutlery; andIdohereby declare ,that fol-- i lowing is a full and exact description thereof, reference being had to the accompanying drawings, niakiiig i a part of this specification, in which- Y l; 1

Figure I is a perspective of a bolster for knives and forks, and other articlesof cutlery, 'and is the subject,-` matter of this invention. 4 t Figure II is a section of each part of `the bolster. y i J Figure III represents the bolster in section as applied to -a knife blade and handle. i

Figure IV is a transverse section of the same. i 1," l i l The nature of this invention` relates to making a bolster for cutlery of castmetal in two parts-the,` one part of which has a tube or socket, and the other part a projecting prong which, ,when the parts `are put toggtheL enters the tube or socket and wedges therein in a manner to hold the twoparts securely and firmly the handle. Letters of like name and kind refer to like parts in each of the gures. i i

A represents that part of the bolster which has a prong, a', and `may be called the malelpartfandB nepite-` sents thatpartv'hich has a tube-or socket, b', and may be called the female part. l `"Ihiesepartsare madefofcast iron and then annealed, or made malleable, or `other suitable cast metal may be used. Aslit is formedin" thel 1 ,i prong a to receive a wedge, c, as shown in Fig. II, `so that when t-hese parts anepnt `together `the wedge will strike on the bottom of the tube and'be'driven into the slit, and expand and wedgethe within the socket, as shown in Figs. III and Or, inlieu oi' the detachable wedge, na"pei-inailent wedge be formed on the bottom of the socket, as shown at d, Fig. II, which will answer af like purpose, althouglrgI use, l f A by preference, the detachable wedge, c. The slit is niade in the prong hysawling` after the,` metallhasbeen i f annealed. The socket B passes through a hole made in the handle, (the handle being lat,) so as `tobrinD s" l top edge flush withthe handle upon the opposite iside, and so that it may be` riveted-to the handle,` and inl that., manner it is itself -securely fastened to the handle. The male or prong part is then drivenin, and wedges n" the socket as before described, and the two parts are thus drawn closely andiheld firmly together uponlth handle-and blade. The socketl or tube forms a central support to the handle, aiidlthe rims or edges `of lthietvvo 1 parts press firmly upon the outer line of the handle and blade, and thereby a. complete andsutlicientstrengthenf` ing of the handle and blade is eected. (lr,` he parts may be so proportioned thatthe socket will stop short of passing through the handle or shank, and allow its top to rest against the shanki'upon thefgsameside, i, the prong passes through ,the shank and wedges in the socket, as shown in Fig. Either plan may be adopted i A smaller hole in the shank may he made to admit the prong than is required to admit the sooket.-

principlel `of l each, as a inode of fastening, is considered to bethe same. Thisconstructionlforms; avery cheap andisiib` i" stanti'al bolster, and is believed to be preferable to any heretofore constructed.` 4,Itis applicable to knives,` and I forks, and all kinds of cutlery. E represents a` knife-blade, and F the shankoghandleo "The, scales, G, are," C made (at .their end next to the bolster) bevelling, in order to lit under a corr/responding outwardibevel of the bolster, and the scales are otherwise riveted to the shank ina common manner. l i l fyi What I claim as my invention,`and desire to secureby Letters Patent, isf 1 3 l l A cast-metal bolster `for cutlery, made in two parts, A and B, and having aprong a', socket 1b", andwedge` c, (or 11,) for the purpose and substantially as herein described. l Y l `errichtensans.`` t
