`IMIIPRQ'VIElID HORSE HAY-FORK.

The Schedule referred toin theseLetters Patent and making 'Dart of the4 same.

1o`all whom t may concer-a5 I l Be it known that LJ. M. MCDONALD, of McGoys- .ville,.i n the county of Juniata, and State of Pennsyl` vania, have invented a vnew and' useful Improvement m Horse'Hay-Forks; and that thev following is a sufone skilled in 'the artto which -my invention appertnins to carry itl into eiect, reference being hadto the fication. l

My vimproved forklis pf that'class in which the means for engagement-with the loadA consists of a plnrality.. of straightwperpendicular prongs, having points adaptedto readily enter the hay, and tov be turned up, when introduced 'to the. desired extent, to

leased.`

My invention consists inI an improved construction and arrangement of the prongs, and ina n-ovel com- In the drawings-f Figure 1 represents a perspective view of my im-v proved fork in the pbsition in which it is forced intov lFigure 2 is a sectional elevation of the same in the position in .which it is locked to retain a load.

' Similar letters of reference, indicate like parts in the two iigures.

A A represent a'pair 'ofheads of suitable form and material (preferablysimilar in both respects) to support the desired number and nature of prongs. vB B B B' B B represent stems, depending from the heads A. and A', respectively, the latter passing through the head A preferably inside ofthe others.

O O0 represent points, which are substantially of the form represented, being constructed-with inclined cutting-edges, c, on the inner sides,andvattached to vthestems B. Bby'hinge joints ot' suitableform to adapt them to beheld in the two positions shown.

The points G and stems B B c'onstitutethe prongs of the fork, which are preferably threein number-,as shown, being arranged relatively toeach other, as represented, ,with the cutting-edges c of" the points pressed between them in the act of entering the fork,

held, the flatoutward-projecting supports provided by the points constructed of Ithe, form shown, and thus resented in fig. 2, serving further to secure this; saide arrangement serving further to center the fork, and retain it in an' upright position while it is being entered. l A

D represents a standard, projecting centrally from the head A, for the attachmeutof the hoisting-rope,

the head A being provided with l a suitable orifice for its reception, and sliding looselyon it to permit or .impart the movements of the points.

. E represents a case, formed'on or attached to the head A' in a radial position, and4 adapted for thereception of a spring latch, by which to lock the points through their connections in ltheir two positions.

-F represents .the latch, which may be of any snit- H, a, lever, suitably applied to withdraw it from said socketsd d. I

I represents a projection, provided on the head A', for the attachment'of the lever H.

K represents a projection, provided on the lever ll,

to form a stop to limit .its movement.

L represents the hoisting-rope; M, the trip-cord; and

Z on., rings (for which any equivalent provision may be substituted) applied to the standard D and lever H for their attachment.

vThe precise form' and proportionsof the severa-L parts will vary according to the material of which they are composed, the taste of the manufacturer, 85e. I preferably construct the head A with the stand, ard D, and the head A with its latch -ease E and projection I, of cast-iron, the pointsC of steel, the Stems B B', lever H, bolt or latch F, vthe rings l m, and the pntles ofthe several hinge-joints, of wrought iron or steel, and the spring G of steel wire.

`The operationof the fork is as follows: 'lhe parts 'being in the position represented in iig. 1, with the latch F4 in the socket d, the prongs BB' (J B B C are simultaneously forced into the hay by.. pressing on the head A, the edges c of the points cutting a passage for them. On their insertion to a properv depth, the latch F is retracted by means of the lever H,'a'nd.the head A is forced down, actuating through its stemsB the points, and forcing them into the position represented in iig. '2, when the latch F is vforced bythe vspring G into the Vsocket el' ofthe stand-.

- veyed to the desired location, when the trip-cord Mis drawn on and .through the'leverjH, thel latch F retracted, thus discounectin g the head A from the standard D, allowing the load, by its weight on the points C, to return vthem tothe position represented in iig. 2, and slip cti'.

The fork mayhnve any preferred number of prongs more than two.

The combination of devices forY supporting and op momo spring catch F d', all constructed and adapted to op- ?rae substantially as and for the purposes herein set ort i.

lo the above specification of my improvement in horse hay-forks 1 have signed my hand this 22d day of J une, 1869.
