` Aindicasae axle; i

B, the wheels; 'and O, the thills, arranged in the peculiar and relative positions shown."v Y

Above the axle A; and supported thereon by the standards D D', are two shafts, E, on which are, ar-

`rang several cranks, a, which operate the spreadinglever The outer lends of theshafts E .are provided with small gears, b, which mesh into large gears, Gr, fastcned to the inner, sides' of the wheels B, from which 'the shatts E and spreading-levers F derive their mo- The lower end ofthe hand-lever H is bent, to form a bell-crank, H', and pivoted to one ofthe standards D.

`'lhe `end of the bell-crank H is connected, by the rod d, to the inner ends of two'levers, c, that extend'` along the front' side of the axle Ayto/which they. are

Figure 5 represents a side view of one of' the spread-` pivoted',Y near their centers, 4 by screws'or boltsf, andI theirouterends arfe fastened tothe upright slides, g,

at the front 'side of the standards Di.,v l.

',.lheslides g are furnished with, forks, 1, aboveand below thebearingsc, which are moved up. and down.

yby thelevers e, slots being formed inthe top. ofA the standards D, win which the bearings c are held.

` rEhe spreading-levers F are made, in,` this instance, in curved form, as shown in thedra-wing, their upper ends being attachedtofthe cranks a, while their centers are pivoted or hinged to the endsof swingingf' arms, I, and their `lower ends'l furnished with spring forks, k,

. The forward endssof the swinging-ai'rns are held between eye-pieces, J, fastened to the bottom of the axle A. said arms I being secured by a single rod, 2,

that passes through the ends of all the arms I and eyepieces J, as fully indicated in the drawing.

. Instead of a single ro'dfor fastening all the arms I, they may be fastened separately or in sections of two yor more, as desired.

tlhe forks, K are constructed vand fastened to the l spreading-levers F inthe manner shown in figs. 5 and 6.

`lllletallieplates, tare secured to each side ot' the lever F by a bolt h, and passing vthrough their lower.

ends, as well as t rough the end ofthe lever, is a pin, m, the ends of which project a'sliort distance at each side'. Y

The wires, lw, that form the tinesof tl1eforks.K are coiledto fit around the projecting ends of the pin m, thereby forming a spring to v give the required amount of elasticity `to the fork. y 7

One end of the wire is bent to form a hook, which is inserted ina hole through the lower end ot' the plate '13,- the other projects downward, andis curved, to 4form thetne of the fork, all of whiehis fully ndicated in the drawing. y

The thills, O, have fastened to their rear ends metallic arches, L, tha-t pass over the top of the axle A, and are secured at -the back thereof in eye-pieces, 3,]

said eye-pieces 3.being bolted'fto the under side of the axle and projecting to the rear.

By this method of attaching the thills C to' the axle' A, -th'e `latter canbe readily turned to adjust the height of the forks K from the ground, a hand-lever, M,be ing vprovided for the purpose.

The axle A., and parts attached thereto, are rei tained at theproper degree of elevation hyl meansot a curved bar of metal, N, fastened to the cross-bars,A

A spring, p, is attached to the lever M to press it firmly into the notch fn, and prevent it from working ont of place when the machine is in motion.

A seat, P, is arranged for theoperator upon a-spring support, S, which is fastened to the cross-bars 0 of the thills O.

By having the plates i recessed or grooved out on I their inner sides, the hooked end of the fork is re tained in position, while, at the same time, it facilitates vthe insertionand removal of the hook of the fork.

In` lieu of attaching the arm N to the cross-pieces of `the shafts, I contemplate attaching the arm to the axle A, and have a catch-piece arranged upon, the cross-piece.

` By arranging the forks and their operating mechan ism in the manner shown, a very compact vmachine is produced, while the draft is much less than the Bnllard machine,'upon which mine is van improvement. Then, again, by the combination of the'thills with the axle, asshown, the operation of raising and lowering the forks is rendered quite easy and convenient.

It will be noticed that the weight of the rear ends of the shafts, as well as the weight of the`driver,

tends to bring the forks down toward the' ground,`y

while the action of the forks tends to roll the axle for? ward; the two forces thus, -in a great measure, coun tei-balance each other.

Having described my improvedhay-todder,

What I claim therein asl new and of my invention, and desire to secure by Letters Patent, is- 1. The 'combination and arrangement, with the the manner shown and described.

main axle and crank-shafts placed vertically, or nearly' so, above said axle, of the spreading-fork levers, connected, at their upper ends, with the crank-shafts, and hinged, at a point intermediate between their two ends, to supporting arms, which, in turn, are hinged to the main axle, substantially as shown and described.

2. In combination with the main axlecrankshafts, spreading-fork levers, and their hinged supporting arms, arranged as hereinbefore specified, the ythills or shafts, when arranged so that their rear ends, or brackets,`cr straps, for supporting the same, shall be as shown and described.

2 5. In a machine for spreading hay, the arrangement of the spreading-forks and mechanism for adjusting, operating, and supporting the same upon the main axle, whichcarries the driving-wheels, substantially in 4. The combination, with the crankshafts, l and their supporting standards,

ofthe adjustable bearings c, and system ,of levers for operating the same, constructcd and arrangedupon the main axle, as herein shown and described.

5. The combination, with the fork-levers F, of the plates c', the pin m, passing through the lower end of said lever and plates, andl the forks w, coiled around the projectingend of the pin, and having their hook ends held between the said lever and plates,in'the manner shown and described.
