TO ALL WI-IOM II MAY CONCERJ:

` i Be it known that I, HORACE BAKER, of Cortland, in thc county of Cortland, and State of New York, have invented a new van'd useful Machine for Loading Hay; and'I do hereby declare that the following is a full, clear, and exact description of the saine, reference being .had to the .drawings already on iilein the Patent Office, and made a p artof this specification, in which- Figure 1 is a. perspective view.

Figure 2 is a side elevation, showing the h'ox and gearing.

Figure 3 is a detached view of front rollers. r t,

Fguse: is a section showing the relative position of the horizontal rollers, pulley, and apron.

My invention relates to machineslfor gathering the cnt grzs's rad raising it from the ground and loading it upon a wagon. The machine is hitched to the hind end of the wagon, and follows close to the end of the hayrake, upon which the hay falls as it is raised by the machine.

The construction of thcapparatus will appear from Vthe following description:

A A are the sides of the main frame, towhieh the machinery is attached. B, the .driving-wheels, are attached to fired axles, projecting from and secured tothe sides A. On the inner 4face of thehub ofthe wheels isa ange, represented as in section, in tig. 2, and marked B2. The rest of the Wheel is not shown in this figure, with the exception of the pawl B, which is pivoted to the huh of the wheel, and pressed outward by the coiled spring B3, attached to the flange B2. On the axle I) also revolves the cup-formed wheel C, which has an internal ratchet cut on the inner face of its externallyprojecting flange, in such manner that the pawl shall press against and carry this wheel with it when the driving-wheel B is turning forward, but'when the drivingwheel is turning backward, the pawl slipping over the inclined faces of the ratchet, the .vheel C will not move.

-The flange c is finished on the exterior face nearest the rim, as a pulley, to receive the belt O, and on the opposite side, on theportiou forming the end or solid part of the wheel, is placed the spur-gearing e2.

Between the wheel C and side A, there are also attached to the boxes D straps E, which turh on theaile freely, and have a wrist-pin, E', projecting from the other`end, parallel with the main axle, and sustaining the spurwheel.F,'meshing into'the spur-wheel C2 on one side, and on theotherinto the twin spur-wheel H, which, revolves-upon thc projecting end of the shaft I. This shaft is attached to the wrist Ehy straps G on ea'ch side ofthe twinspur-wheels. 'lhese straps fit/loosely upon -their respectivehearings. The shaft I passes through ILjn the side A, and the straps Gand/ allow a free play to the shaft I, forward and back, without deranging the gearing, for purposes whiely'will heV hereafter explained. i

Opposite the spurwl1eels-F G, the spur-,wheel K is also geared into the spur-wheel G2, communicating motion to the shaft L. The spur-wheels F, H, and K, are all of the same size.

The two sides of the machine are nishcd in the same manner. i

The shafts I and L pass through the sides A, and across the machine, the shaft I having a play backward and forward in the slot, as described. i

0n each ofthe shafts Land L are pulleys, R 1i', having pyramidal projections Afrom their rims, working into the open links ofthe four endless chains S S. Intermediate wheels, Rg, of the same size as the pulley-wheels,

- are placed upon the shafts I andfL, between the pulleys, and haring projections or teeth upon their outerrims.

T '1" are four wooden standardsfmade as small as consistent with the requiredvstrcngth, so as to afford in them the necessary elasticity required for keeping the aprons face to face, and at the same time to increase or decrease the space between the aprons, as larger er smaller quantitiesoi-` grass pass through. They areattached' to the sides A, and stayed by lugs, cast on the sides, as represented.v '.lhey are bent at their upper ends, and receive the two cross-guide boards, t t,'for directing the hay on to the wagon. Across the standards, immediately below the curves Vin them, are attached the countcrshafts u n', journalledupon the front and rear standards respectively. On these shafts are pulleys', 't' v', corresponding to thc pulleys R R2. The endless chains,

--S S', pass over these pulleys also, the open links meshing upon projections thereon. Bars -W W are attached to thge endless chains respectively, forming two elastic endless aprons.

The raking-apparatus shown in fig. 3 is foundunnecessary in practice, and I therefore donot describe thel same, or make any claim thereon.

In operating this machine, it is attached to the hindved of the wagon. -The endless a'prons work neanto the ground, the rear one much the closer to the ground, the forward one high enough to pass over the hay. The projections or teeth upon the wheels R on the shafts I and L, between the wheels R R,piek up the hay and direct it between thefaprons, and as they revolve in' opposite directions and close together, the hay is carried upwerdsbetween them until it strikes the guide-boards, and is by them directed forward on to the wagon. The shaft which carries the forward apron playing in the slot I', is pressed forward when a, larger quantity of hay passes in, but as such quantity decreases, the shaft I is pressed backward bythe bow-spring'lz. The elasticity of the standards T Tacts correspondingly upon the upper portions of the `aprons, the'space between the aprons being 'thus governed by thequantity of hay passing between them; and also such space may be expanded or contracted at eitherend independently of the other, so that a large quantity of hay may be being carried at one point, and a small quantity at another. Y

What I claim, and desire to secure by Letters Patent, 4is l. The .two positively-actuated endless aprons, revolving in opposite directions, incombination with the toothed wheels Rz, or their equivalents, upon -the shafts I' and L, and so placed relatively that the hay may be picked by` such-toothed wheels, and directed between the aprons, andby them elcvatedfsubstantially as and for the purpose set forth. l f i 2. I claiui the standards T T, when so constructed that by their elasticity they shall maintain the upper portions of said aprons fece to face, and permit variations in the quantity ofhny carriedbetween `them, as

set for-th.

3. In combination with said endless aprons, I claim the guide-boards, so constructed as to pass `the hay over'the forward apron and'on to the wagon. l

4. In combinationpwith seid` endless aprons, I claim the spur-wheels F and H, and the shaft I operating in the slot I1, and so constructed as to allow 4of a forward and backward movement of such shaft and forward apron, substantially as and for the pnrpose set forth.f i Y HORACE BAKER.
