ATTACHING HANDLEs To CUTLEHY;

Speccation of Letters Patent No. 26,478, dated December 20, 1859A f A i `To all whom it may concern."

y Be it known that I, MATTHEW CHAPMAN, of Greenfield, in the county of Franklin and State of Massachusetts, have invented a new and Improved Mode of Attaching Handles to Cutlery and to Implements or Tools of Various Kinds; and I do hereby declare that the following is a full, clear, and exact description of the same, reference be ing had to the annexed drawings, making a part of this specification, in which- Figure l, is a back viewof a table knife having its handle attached to it according to my invention, the handle being partly bisected. Fig. 2, is a detached side view of the tang of the blade and its nut.` Fig. 3, is a detached edge view of ditto.

Similar letters of reference indicate con responding parts in the several figures.

The object of this invention is to `oloviate the use of cement in securing handles to cutlery and various tools, and to obtain a firm and durable connection of the two parts by a very simple and economical means. f

In the annexed drawings A, represents the blade of a table knife. B, is its tang. The tang is of the usual length, or taper or conical form and has a screw thread a, formed on its lower end. This screw thread is flattened or filed off at two opposite points so as to form plane surfaces b, one of which is shown clearly in Fig. 3.

C, represents a `small metal cylinder which is iitted transversely in the handleD, and passes entirely through it. This cylinder has a hole made through it transversely, said hole having an internal Screw thread to t the screw thread a, of the tang. The cylinder C, is adjusted in the handle D, with its hole in a vertical position so as to receive the lower part of the `tang B, which is fitted in the handle D, as usual a proper hole being made longitudinally in the handle for its reception. The blade A, and tang B, are turned and the tan is conse uently drawn within the handle and the bolster c, of the blade is firmly pressed or drawn on the end ofthe handle by the screw a, of the tang and the cylinder C, lwhichis` in fact a nut. `Whenthetang B,is snugly fitted in the handle D, the ends `ofthe cyl?" :.z

hole made to bear against the flat `orplane@` sides of the screw a, thereby eifectuallyl pre-f venting the turning 1oit the tangwithinyit.` y By this arrangement the handle firmly and permanently secured to :the tang, the g cylinder or nut @,of course prevents the direct withdrawalof; the tang` from the handle, while the close adjustment `of the i cylinder to the plane "surfaces `3),",eiectually prevents the turnimgof` thetang'jandhthe consequent liability of its `becoming loose. l

I am aware that tangs havebeen secured in handles by rivets,but` they can not bei firmly secured in that way `without the aid 1 of cement, it being impossible to prevent l f a play and rattle by the rivet alonerf` The" cement as is `wellknownis soonsoftened by washing the cutleryfin hot water and` oozes` 1I; 3 out between the bolster and handle leaving the tang in a loose State. Bymy invention $1". the cutlery may bewashed in hot water t0 "75` least liable to `be injured in any way," and 1i i the connection between the handle and the n will last as long as the `implement facilitate cleansing `without `being in; the

tane itseIf.

Having thus described my invention what I Claim 1S 116W and desire to secure by Let` ters Patent, is,-` i v Securing handlesfto cutlery, and other tools or implements, by having a screwf i, thread a, formed on the tangs B, and` provided with plane longitudinal surfaces "b, in connection with the cylinder or` nut C,l litted in the handle andhamineredor com-` pressed to tit the `screw a, and; its plane sur-1.:` faces b, substantially as and` for` the pur-` pose set forth. y
