IMPROVEMENT IN GUTLERY.

@Le Srlgnm'lc netta; tu 'iu tlgcse Etnias ttent mit mating putt tf tige samt TO ALL WIIOM IT MAY CONCERN:

Be it known that I, JONATHAN BALDWIN, of Northampton, Hampshire county, Commonwealth ot' Massachusetts, have invented a new and useful Improved Method of Attaching Knit`e-IIandles to the Blade without the use of Rivets; and I do hereby declare that the/following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

My improved method of fastening consists in attaching the two scales en each side of the tang of an ordinary house-knife by means oi' metal poured in through a slot or slots in the tang or scales themselves, which shall run through the tang at certain openings and iill into dove-tailed slots in the scales, and on hardening shall bind the whole together firmly. The shoulders at the junction o'l the blade and haft can also be attached in a like manner. In the drawingv Figure 1 represents side view of the tang of the knife, one scale having been taken o" and the metal fastening cut ott` where the junction was made between the deve-tails on either side, and shown in the figure by the section lines. In this A A is the groove or slot cut lengthways through the tang B and filled with the east metal. At C C are the connecting points where the metal runs either side into the dovetailed slots eut into the scales. At these points the groove in the tang is merelyenlarged so as to allow ,the metal to till the dove-tails more readily. D and D are small connections between the dove-tails 'at C', which serve to bind this point more strongly. AtE is a square slot through the tang, and forming the end of the slot A. This serves to make a connection between the shoulders F F, the shape of which is shown in Figure 3, where is shown the east metal filling the dove-tailed chambers a a, and attaching them together against the sides of the tang.

Figure 2 shows a plan View of the handle of my knife, in which is seen the manner in which the poured metal binds the scales X and Y to the tang. In iig. 1 it is seen thatV the slot A in the tang does not extend entirely to the end, but leaves asmall connection between the upper and lower portions, in order that the metal can be poured into this slot. At this end a small groove, o, in each scale through which the metal runs in the slot A, is eut. This also forms a shoulder to prevent the scales from slipping back. The position of these grooves is shown by dotted lines in either figure. rEhe metal used for filling may be a'eomposition of white metal and of' any suitable hardness. i

By this means I accomplish the fastening of the scales and shoulders upon 4the tang without the use of rivets, makinga very neat handle and avery strong one, for the metal in cooling, after it has filled up the dove-tailed grooves, shrinks and binds the whole together much more iirmly than could possibly be done with rivets or bands.

In my handle the shoulders can be fastened by rivets or any ordinary way, while the sea-lcs can be fastened on in the manner already described.-

New, having described my invention, what I claim as new, and desire to secure by Letters Iatent, is-

l. The method of attaching the sea-les of a knife-handle to the tang, by means of dove-tailedv grooves eut. into the former into which metal is run through the tang, substantially as herein described.

Q. ,lhe method herein described of attaching the'shoulders F F to the tang, by means of the dove-tailed grooves (l t and metal enst in, substantially :is shown.
