.To all whom it may concern.-

Be it known that l, STEPHEN H. GARST, a citizen of the United States, residing at Greenville, in the county ofDarke and State of Ohio, have invented a new and useful Improvement in Mannre-Distributers, ofwhieh the following is a specification.

My invention relates to an improvement in 1nanure'distributers5 and it consists in the peculiar construction and combination ofdevices, that will be more fully set forth hereinafter, and particularly pointed out in the claims.

In the drawings, Figure 1 is aside elevation of a manuredistributor embodying my im provements. Fig. 2 is a similar View of the opposite side of the same. Fig. 3 is a top plan View. Fig. at is a vertical longitudinal seetional view taken on the line at w of Fig. 3. Fig. 5 is a vertical transverse section on line Figs. 6, 7, S, 9, and are detail views. Fig. it is a detail view of the drum and the ropes for working the flexible platform;

A representsthc running-gear of a wagon, and B the front and rear bolsters, upon which are supported a pair of longitudinal beams, O, which have their front ends connected by a cross-bar, D. i

F represents the side boards, which are secured on the upper edges of the beams O, and have their front ends connected together bya From the side beams, C, de pend four standards or hangers, H, at the rear portion of the body, formed by the beams and boards above the side, and the lower ends of the said standards or hangers are secured to longitudinal parallel bars I.

K represents a pair of cross bars, which connect the under sides of the bars I, and on the said cross-bars are seen red longitudinal parallel bars or slats L,which are triangular in crosssection, as shown in Fig. 5. One of the bearing-wheels on the rear axle is provided with a sprocket-wheel, M,- which is rigidly secured thereto and rotates therewith.

On the inner side of the side beams, O, are a series of anti-friction rollers, N, which are journaled on spindles extending from the side beams to bars 0, which are arranged at a suitable distance from the inner side of the said side beams.

19 representsa drum, which is journaled between the rear ends of the beams O, and is provided with disks or rollers R, which bear against the inner rear sides of the beams C.

At the front end of the frame orbodyis a pulley, S.

T represents a flexible platform, which coinprises a series of transverse boards, U, arranged side by side and hinged together, as shown. This platform is supported upon the rollers N, and normallyserves to form the bottom of the wagonbody. I

V represents a rope, which passes'over the pulley S, and has one end connected to the front end of the flexible platform and the other end connected to the rear end of the said flexible platform.

\V represents a transverse vertical board, which is secured to the front end of the platform '1. To the inner side of this board is socured the upper edge of a rearwardextending concave shield, X, which shield is preferably made of sheet metal.

Y representsapulley, which isjournaled in a bracket, Z, that projects rearward from th front bar, D.

A represents a rope, which has one end secured to the roller 1? and coiled thereon, and from thence the said rope passes forward around the pulley Y and then backward, and has its opposite end attached to the front board of the platform.

B represents a rope, which has its frontend attached to the front end of the plat-form, and its rear end connected to and coiled upon the roller P in the direction opposite the coils of the rope A. t

From the upper sides of the beams (J, at the rear en dsthereof, project standards O,in which isjournaled a transverseshaft, D. To that por tion of the said shaft which is between the standards is secured a cylinder, E, which is provided with longitudinal parallel slats F, from which project radial teeth G. The said cylinder is rigid with the shaft D, and is thereby adapted to rot-ate therewith. One end of the shaft 13 extends through and projects beyond one side of the frame or body, and is provided with alongitudinal groove or feather, as shown. H represents a sprocket-wheel, which is loosely mounted on the projecting end of the shaft D.

1 represents a smaller sprocket-wheel, which L represents a sliding clutch, which is feathered on the outer side of the shaft D, is adapted to engage the sleeve K, and thereby lock the sprocket-wheels H and I to the shaft, and on the outer end of the said clutch is formed an annular peripheral groove, M.

N represents the bracket arm, which is bolted to and projects from one side of the bed or body, and is arranged behind the projecting end of the shaft D. To this bracket-arm is fulcrumed a lever, O, which has one end extended forward to form a yoke-arm, P, that engages the groove of the sliding clutch, and the opposite end of the said lever is bent at right angles to form an arm, R.

S represents a hand-lever, which is fulcrumed to the bed or body near the front end thereof, and the said lever is connected to the arm R by means of a rod, T.

U represents a bracket, which projects from one side of the bed or body, at a slight distance in advance of the projecting end of the shaft D, and to the said bracket is loosely journaled a small idle sprocket-wheel or pulley, V, which is arranged out of line with the sprocketwheels H and I. l t

W represents. an endless sprocket-chain, which is crossed, passes around a sprocketwheel, M, over the sprocket-pulley V, and

over one ofthe wheels H or 1, according to the speed at which it is desired to rotate the cylinder when the machine advances. If the sprocket-chain passes over the wheel H, the,

cylinder will rotate slowly; but if it engages the wheel I the cylinder will be rotated at a higher rate of speed, as will be very readily understood.

By means of the lever S, the lever 0, connected thereto, and the sliding clutch L, the sprocket-wheels H and I may be rigidly locked to the shaft D, when it is desired to rotate the cylinder when the machine is in motion; or the clutch may be moved out of engagement with the sleeve K, so as to permitthe sprocketwheels to turn idly on the shaft D, and thereby cause the cylinder to remain at rest, when the machineis-in motion and not in operation.

One of the spindles of the drum P projects beyond the bed or body on the side opposite theprojecting end of the shaft D. On the said projecting spindle of the drum P'is rigidly secured a pairof wheels, X, which are of the same size, and are arranged at a slight distance apart. Each of the said wheels is provided with two series of peripheral ratchetteeth, Y and Z, which extend in opposite directions.

A represents a pair of levers, which are pivoted to the projecting spindles of the drum and bear against the outer side of the wheel X. To each of the said levers is-pivoted a detent or pawl, B having 'a pair of oppositely-extending arms, one of which is adapted to engage the ratchets Y, and the other is adapted to engage the ratchets Z. The said dogs or detents are also provided with rearward-extending tappet-arms O".

D represents a pair of springs, one of which is secured to each lever A". The said springs curve rearward and downward from the said levers and have their lower ends curved to form offsets FF. The said offsets are either adapted to bearnpon the upper side of the rearwardextendin g engaging arms of the dogs or detents, to keep the same in engagement wit-h the ratchet-teeth Y of j the wheels X, as shown in Fig. 2, or, when the dogs or detents are turned so that their front arms are caused to engage the teeth Z, the said springs, by bearingagainst the rear end of the rear detent-arms, maintain the said detent in this position, as shown in Fig. 8. y

F represents a crank which is on one end of the shaft D above the wheels X.

G" represents a lever, which is provided in its upper end with a longitudinal slot, H, the said slot being beveled on opposite sides. (See Fig. 10.)

L represents a rack-bar, which is arranged on the outer side of the lever G". The lower portion of the said rack-bar is secured in a guiding-clamp, N bolted to the said lever, and to the upper end ofthe rack-bar is pivoted a pitman, M by means of -a bolt, K which extends through slide-blocks 1", fitted in the beveled slots of lever G. This enables therack-bar to be vertically adjusted on lever G". The rear end of the said pitman' is pivoted to the wrist-pin of the crank F.

0 represents a spur-pinion, which isjournaled to a bracket, P, that projects from the beam 0 in advance of the lever G". This spurpinion meshes with the teeth of the rack-bar said rods are pivoted to the upper ends of the levers A S represents a spur-sector, which is pivoted to the beam 0 in advance of the pinion O", and engages the same. ner of this sector projects an arm, T.

U represents a rock-shaft, which extends across the front end of the bed or body, and isjournaled in the side boards thereof. One end of the said rock-shaft is provided with a crank-arm, V that is connected to the upper end of the sector-lever T? by a rod, W. To the opposite end of the said rock-shaft is secured a hand-lever, X which is on the same side of the bed or body with the lever S, and is provided with a spring-actuated detent, .Y",

adapted to engage the teeth of a segment- From the upper corand alsoprovide a securing" or pivotal point for the rack-bar L and the pitman M. The lever G is fulcrumed upon a journal which extends outward from the beam G. Thelever or link G does not move up or down, but has only an oscillating motion. The longitudinal motiongiven t the lever G is derived from the pitman M. It will be understood that both the pitman M and the rack-bar L are pivoted to the blocks 1", so that as the rack-bar L is raised up or down by the pinion O the blocks 1 are raised or lowered, and as the pitman M isjournaled to the blocks I said pitman follows the movement of said blocks. Raising the block and pitman gives the lever G a shorter oscillating movement, while lower ing the pitman and blocks gives the lever G a longer movement. This short and long movement of the lever Gr causes the pawls or detents to engage a less or greater number of ratchetteeth in the wheels X.

A represents a bell-crank lever, which is fulcrumed to one side of the main frame in rear of the wheel X. At the front end of the forward-extending arm of this lever is a crosshead, B, which is arranged under the rear end of the tappet-arm C (3 represents a lever, which is l'ulcrumed to one of the side boards of the bed or body near the upper edge thereof, and has its upper end bent inward at right angles to form a horizontal arm. Its lower end is connected to the vertical arm of the bell'cra-nk lever byarod,E

F represents a coiled extensible spring, which bears againstthe rear side of the upper portion of thelever 0 From the upper side of the front board, \V, on the flexible platform, at one end thereof, projects a horizontal rod, its front end bent upward to form a verti cal rod, G the upper end of which is bent outward nearly at right angles.

H represents a spring-detent, which projects from one of the side boards of the bed or body, normally engages the upper end of the lever O to retain the said lever in a vertical position, and is provided at its frontend with aforward-extendingupwardly-inclined arm,I.

The operation of my invention is as follows: The platform is normally in the position indicated in Fig. 3, when stretched longitudinally over the rollers N and forming the bottom of the bed or body, the front end of the said plat-form being in contactwith the front end of the bed or body. The latter is then filled with manure. WVhen the machine isstarted and itis desired to spread the manure'on theground, the driver moves the lever S to cause the clutch L to engage the sleeve K, and thereby lock the sprocket-wheels H and l to the cylindershaft D, as before described, and the rotation of the sprocket-wheel'M, attached to one of the supporting-wheels of the machine, is imparted to the cylinder by the cross-chain W, thus causing the cylinder to rotate in the direction indicated by the arrow in Fig. 4. AS the said cylinder turns, its teeth engage the manure in contact with the cylinder and cause the same to be evenly distributed from the rear end of the bed or body onto the ground. As the cylinder rotates, its crank F imparts oscillating motion to the lever G by reason of the pitman M. The oscillating motion of the lever G is commu nicated to the levers A by the rods R The lever 0 being normally engaged by the sp1'ing-detentH ,tl1e bell-crank lever A is maintained in the position indicated in solid lines in Fig. 2, with its cross-head l3 lowered and out of contact with the tappet-arms C of the pawls or detents, and the springs .D keep the rear ends of the said dogs or detents in engagement with the teeth Y of the wheels X. Inasmuch as the rods B have their front ends pivoted to the lever G on opposite sides of the fulcrum of the same, the levers A are caused to oscillate simultaneously in opposite directions, as will be readily understood, thereby causing one of the dogs or detents B to slip' idly forward on the teeth Y of one of the Wheels X, and causing the other dog or detent to move rearward in engagement with one of the teeth Y of the other wheels, X, and thereby the drum P is kept in constant rotation in the direction indicated by the arrow in Fig. 1. This rotation of the said drum causes the rope B to be wound thereupon and to draw rearwardly on the front end ofthe flexible platform, and the lower side of the rope A uncoils from the drum, thus slacking the upper portion of the said rope, and thereby permittingthe frontend of the platform to be drawn rearwardly by the rope B. The rear end of the said platform thereupon moves downward over the rollers R and hears upon the bars L. The ropeV has its upper side tightened as the front end of the platform moves rearward, and thereby causes the lower side of the ropeVto draw the lower end of the platform on the bars L. It will be readily understood from the foregoing that as the platform ni'ioves rear ward it presents the manure to the cylinder, and thereby keeps the latter constantly at work in distributing the same.. By the time that the board W reaches the cylinder the manure has been entirely discharged from the platform. The function of the shield X, which is adapted to the contour of the cylinder, is to prevent any of the manure from remaining lodged in the lower front corner of the plat form.

The speed at which the cylinder rotates may be regulated by applying the sprocket-chain \V to either of the wheels H or I, and the speed of the sliding platform may be regulated and caused to coincide with the rate of rotation of the cylinder by moving the lever X so as to actuate the sector S and cause the pinion O to either raise or lower the rack-bar'L and thereby regulate the stroke of the levers A By this means any desired quantity of manure may be distributed to a given area of land, even while the machine is in motion.

When the front end of the sliding platform reaches the rearward limit of its movement, the tappet-rod G strikes against thelower side of the arm I at the spring-detent H thereby raising the said arm and causing the detent to release the lever 0. As soon as the detent slips from the lever, the spring F forces the lever 0 forward, thereby causing the rod E to move rearward and partly turn the bellcrank lever A and causes the cross-bar B to turn the dogs or pawls B to the position indicated in Fig. 8, with their frontends engaging the teeth Zof the wheels X, which causes the rotation of the said wheels to be reversed, as will be readily understood. This reverse rotation of the wheels'X causes the drum P to rotate in the contrary direction from that indicated by the arrow in Fig. 4, which causes the platform to be returned to its initial position in its front end bearing against the front end of the bed or body.

A machine thus constructed is adapted to spread manure in any desired quantity upon a field, is automatic in its operation, and will be found of great utility to farmers.
