IMPBOVBIENT IN AGBIULTUBAL PURKS.

TO ALL WHOM IT MAY QONCERL.

Bc it known Lhat'AnaAn CLow, Guiness Chow, and lCnnnmse CLow, of Port Byron, in tlioecnnty nF Cayuga, and State of New York, invented a new and useful Improvement` in Grain-Fork and we ilo'lmrnby declare that the following is n. full, clear, and exact description thereof, which will enable those skilled in the i ar't to make and use the same, reference being had to the ccompanying drawings, forming part of this specifi kation', in which- Figare 1 is a view or our invention. lfigare 2is a front view of the metallic hca'd; and v I, y

Figure yBiss. vertical longitudinal section of the head, taken through its ecrit-rc. Similar letters of reference indicato like parte in all vthe ligarcs. l Heretofcre in thc construction ofgrain-forks wooden heads have been used, the tlnel of sach n. fork being secured in the hcadby forming n tenen on the -bsse of each tine, andl driving it intojs. suitable moi-tice in the wooden hond, tho tines beingjdriven in from the-front eide-ot the' heid. These vt'orlrs have this objection: the head is liable; to bc split by tho leverage of the tincs when in use, unless the head Ais made so heavy as tobc cumbersome and clumsy; and the tinos project from the headsquarely to the front, or hareno lateral/spread st the pointot the fork, and thus reqaire arlongand heu; hesdinordert'o getasnieientwidthof fork in f. this class of fork tincs of thirty inches in length are used; and, however well inade, it is a diicult matter, Aif

not an impossibility, to combine in such construction strength and 'durability with useful proportions and neatness. The tines are also apt to werk loose with use, and by the swelling and shrinking of the parte. To

l obviste these objections we use a mallcoblc,lcssbiren, or metallic head, which 4gives the desired durability and i. t' strength lwith light and symmetrical proportions, and greatly enhances the practicalvalae of this implement.

' Thisinventionconsista in the employment of a metallic head in connection with the long wooden ytines of -I this class ol' fork 3 dalso, in an improved arrangement of cest metallic ribs er braces between the sockets of the head, for obteiningtho greatest strength with 'lightness of heed; also, in the use of conical sockets, tapering from the rear to'the front'sde of the head, so that'thetnpering tines may be driven in from the rear side of the heed, and wedged or, eea ted`so .iirmly in their sockets thatthey remain permanently liked and rigid in their positions; also, in'formingthe tine-sockets in the head at s. diverging angle with relation te each other, so that the beldmay he contillctcd in length, for diminishing its weight, and the forli retain its spread of tines at its point lesubei'ore'; also, in attaching the braceand bow of the fork to anch other insach manner as to fold together,

fer-packing, without boingv detached from each other ,11nd, further, our invention consists'in hinging or jeinting the bow ca the hoed in such a manner as to be capable of being foldeddown upon the -tincs of thc fork when released by the brace, es hereinafter more fully explained. Y

-In thefscoompanyng drawings, A is n. metallic bend;` B B nrc the wooden tincs; 0 is the handle; D the v bow, endE the brace. The head A has conical sockets'a a, (iig. 8,) tapering'from the Aroar of the head towards itsfrnt." The tines B are, turned in a tapering forni, from point to base, and are then steamed, bont to the proper curve, and thoroughly dried 'or seasoned, when they are ready for driving. They are driven in from the rear side of thc head, and begin to fill up and jam in their sockets at a point seine inches from their base; but, being forced forward, they are'vcry firmly and sccrcly fixed in p'osition by the time they nrc fully sented, and

. without liability of rupturipg the head.

For diminishing the weight of the'hc'a'd, und for making n saving of material, we contract the head in length;

and sro ennblcd to de this and maintain n proper width of fork by arranging the sockets a a so that from the rear to the front'of the head they diverge laterally with relation'to cach other, as shown in iig. S.`

In the construction of wooden forks it is difficult to got exactly the proper curve in all the teeth, owing to difference of libro in the wood; und, when vthe l'ork is made, the tincs are driven, and their points then brought into line with eachother bytwisting the metallicV head between thc sockets; also, after the fork has gono'into use, some of the tincs straighten ont more or lese by dampncss, and then the samet method is resorted to for 'bringing the points of the fines .in line again. This issn important advantage that a metallic head has over awooden one, as for 'this reason crooked or bent tines canbc used only. inla'meltallic head.

The head A is eastv withsthin'web betweenthe sockets .and on this webwe-cast `oblique brscesor ribs j. These ribs are placed crossing, with relation to each other, Vuponopposite sides of the head, as shown in iig. 2, in which theribs j' of one side of the heed nrc shown, while the disposition of the ribs on the other side of thc hend'iis indicated by dotteillines. By this means we obtain the best disposition of the metal for resisting the twisting vstr-ain to which the head is subjected by use. The brace E is ut'twched to the bow Dby n. hinge-joint', e, so that tho brace and bow may hev folded together for packing withoutdctnching them from each other. The how D is also hinged or pivoted toenchl end of the head by joints l i, iig. 1, "so that, when 'the brace E is.

detached from the handle C, the bow may be laid down on the 'tines of the fork, and, the brace being folded inv with it, they are mode to pack close for transportation. Bythese means the forkjsmed durable, light, and strong, and not subject togct out of order, rand the packing `of forlis for shipment isfncilitnted.

Hoving thus described our invention, what we claim'ns new, and desire to secure by Letters Patent, is- 1. We claim, in combination, the metllio head A and wooden tnes B, substantially as und vfor the purpose herein specified. V Y

2. The arrangement oi the ribs or braces f, running obliquely front socket to socket, and crossing, with relation to each other, upon opposite sides of the head, as and for the purpose setforth.

3. The arrangement of=the sockets a a, 'divergng laterally from the rem'to 'the front of the heed, in the manner shown and for the purpose set forth.`

4. The conical sockets a, when made tapering from the reni' of the heed towards its front, in connection f with the wooden tines B and metallic head A, substantially in the manner Mldfor the purpose set forth.

5. The brace E :ind bow D, when attached to each other with n. hinge-joint, so as to fold together without being detached from each other, substantially in the manner und for the purpose described.

6. Thejointing of the bow D on to the hend,-for the purposcnnd in the ymanner substantially ns described.`
