ALINZOR CLARK, OF SOUTHFIELD, NEW YORK.

IMPROVEMENT IN HAY-FORKS.

4 and I do hereby declare that the following is a full,clear, and exact description of theconstruction thereof, reference being had to the accompanying drawings, forming part of this specification, in which- Figure lisa perspective view of a three-tiued fork, part of the handle being cut 0E. Fig. 2 represents the fork entire and the handle in section. Fig. 3 is a view similar to Fig. 2, but having the center tine taken out to form a twotin'ed fork. Fig. 4 represents the form of the ends of the tines which are secured iu the handle. Figisalongitudinal section through the center at right angles to Figs. 2 and 3.

Similar letters of reference indicate corresponding parts in each of the several figures.

The nature of my invention consists in an A improved mode of inserting and securing the tines in thestoek or handle of the fork, by which the same fork can be used as a twotined or a three-tined fork, according to the nature of the Work to be performed, two tines being better suited for some descriptions of work and three tines for others.

To enable others skilled in the art to make and use my invention, I will describe its construction.

A represents the end of the handle of the fork. B is the l'errule which surrounds it.

C C arethe two outer tines ot' thefork, which are formed of one piece of steel or iron, heilt at. the parts a a fitting in the handle to the form shown in Figs. 1, 2, 3, and 4, a suit-able hole being made in the end of the handle A, into which they are tightly fitted, being also notched into the edges ofthe ferrule B.

D is the center tine of the fork, having its shank d of wedge form, fitting tightly between the parts a a of the outer tines, and filling up the space between them in the holein the han,- dle. The parts a a and the shank d are tlattened, so as to lit more securelyin the handle.

Vhen the tines are fitted in the handle and driven tight a hole is drilled or otherwise made through the ferrule B, passing directly through the handle and through the shank d, and a pin, b, is inserted and tightly driven in. Thehole and the pin should be slightly tapered. The shank d, thrilling a wedge, will prevent the' tines C C from being drawn out, being itself secured by the pin b.

Vhen it is required to take out the center tine, D, to make the fork two-tined a wedge, d', is inserted in this place, the said wedge being of precisely similar form with the shank d, and having a hole corresponding with that' through the handle in which the pin b fits. ItJ is secured by the pin in the same manner as d, being slightly tapered, is easily knocked out, but still can be driven in sufficiently tight to make tines perfectly secure in the handle, so

that there will not be the slightest danger of their becoming loose.

What I claim as new in my invention, and desire to secure by Letters Patent, is-

The manner, substantially as herein described, of forming the tines C C and fitting them in the stock or handle, so that they can be secured in'the stock or handle either by the wedge-shank d of the center tire, D,or by a detached wedge, cl',ot' similarform, and the pini), so as to make either a two-tined or a threetined fork.
