SPECIFICATION forming part of Letters Patent No. 773,505, dated October 25, 1904. Application filed June 1, 1903. Serial No. 159,567. (No model.)

1"!) all whom, it may concern.-

Be it known that we, LOUIS A. KnnNn'and Mo'r'r R. PHARIS, citizens of the United States, residing at lVaterman, in the county of Dekalb and State of Illinois, have invented certain new and useful Improvements in Manure- Spreaders, of which the following is a specification.

This invention refers to manure-Spreaders, and relates to various improvements in the general construction of such Spreaders.

One of the objects of the invention is the production of a manure-spreader the operative parts and mechanisms of which are at all times within the control of the operator from a position upon the drivers seat.

A further object of the invention consists in the provision of means for balancing or equalizing the strain of the drive-gearing for the spreader-cylinder.

A. further object of the invention is the provision of means for automatically stopping the apron-feed when the apron reaches the limit of its rearward travel.

A further object is the provision of means for simultaneously starting or stopping the rotation of the cylinder and the rearward travel of the apron at any time in the operation of the machine.

A further object is the provision of means for altering the rate of travel of said apron.

The invention further relates to a means for returning the apron to its normal position after the spreading operation is completed.

In the accompanying drawings, Figure 1 is a side elevation of a manure-spreader ern bodying the features of our invention, the traction-wheel on the nearside being removed. Fig. 2 is a top plan view of said spreader. Fig. 3 is a longitudinal vertical central section through the spreader, taken on dotted line 3 3 of Fig. 2. Fig. 4 is a perspective view showing the mechanism for operating the apron-traveling means and the spreader-cylinder-rotating means. Fig. 5 is aview, partly in section, of a portion of the apron-traveling mechanism. Fig. 6 is a detail transverse section through the spreader on dotted line 6 6 of Fig. 2. Fig. 7 is a detail perspective view showing the operating mechanism for the clutch that drives the spreader-cylinder. Fig. 8 is a transverse sectional view through said cylinder on dotted line 8 8 of Fig. 3 looking in the direction of the arrow. Fig. 9 is a detail view showing in front elevation the operating-lever for stopping and starting. the machine, also the means for locking said lever in an operative position. Fig. 10 is a horizontal section on dotted line 1O 10 of Fig. 9, showing said locking means. Fig. 11 is a side elevation of the driving means for the apron, together with the means for changing the speed of said apron.

In the embodiment of this invention a vehicle in the form of a wagon is built, the bottom of the Wagon-box being made up of an apron mounted upon a series of rollers at each side of said box and along the middle line thereof and being thus adapted to be moved longitudinally of the wagon-box. The rear end of the wagon-box is occupied by a spreadercylinder rotatably mounted in suitable bearings. The rear wheels of the wagon are traction-wheels and have a pawl-andratchet connection with their supporting-shaft. This supporting-shaft for the traction-wheels is I geared to rotate said spreader-cylinder, a

clutch being provided for connecting said cylinder with and disconnecting it from said driving means. Said shaft has a gear connection with the aprontraveling mechanism, means being provided for disconnecting said apron from its traveling mechanism and for changing the speed of travel of the apron. Between said traction-wheels the shaft carries a bevel-gear, which by suitable connections is adapted to restore the apron to its normal position in the Wagon-box, which restoring mecl anism is adapted to be actuated by said apron when it reaches its rearmost position.

In the drawings. 1 refers to the wagonbody, having the side sills 2 and the center two-part bolster 3, which sills and bolster are each provided with a series of rollers 4 for supporting the edges and middle of the apron to be next described.

The bottom of the wagon-body is in the form of an apron 5, made up of a plurality of transverse cleats 6, flexibly secured together side by side in any suitable manner and mounted upon an endless chain 7, extending through l the longitudinal center of said apron. At its l forward end the apron 5 has an upright end i board 8. To move the endless chain 7, and thus to travel the apron, said chain is supported upon sprocket-wheels 9 and 10, fixed upon shaft- s 11 and 12, rotatably supported in suitable bearings at the forward end and rear end, respectively, of the wagon-body. intermediate its ends the lower portion of the endless chain 7 and the apron 5 when in its rearward position are supported upon an idlershaft 13, carrying the pulley 14.

A rotatable spreader-cylinder 15, having radially-projeeting teeth 16, is fixed upon a shaft 17, rotatably mounted in suitable bearings at the rear end of the wagon-body 1. The shaft 17 carries a sprocket-wheel 18 for receiving the endless chain 19, by means of which the cylinder is rotate l. Power for traveling the apron and rotating said cylinder 15 is taken from the two rear wheels 20 and 21 of the wagon, which wheels are loosely mounted upon a rotative shaft 22, each wheel being connected to said shaft by means of a pawl and ratchet, (not shown,) whereby forward movement of the vehicle is transmitted through the wheels to rotate said shaft, while backward movement of the vehicle causes the pawls in the hubs of said wheels to click over their ratchets. At each side of the wagonbody a spur-gear 23 and 24s is fixed to the shaft 22, and intermediate said wheels a bevel-pinion 25 is rigidly mounted upon said shaft.

To travel the apron backward during the spreading operation, the following-describe l mechanism is provided: A bearing-bracket 26, rigidly secured to the wagon-body by means of the cars 26, is provided upon one side with a stub-shaft 26", projecting outwardly from the wagon-body,and upon its opposite side with an eye or loop 26, adapted to receive and support a shaft-bearing to be hereinafter mentioned. Upon the stub-shaft 2b is rotatably mounted a spur-gear 27, meshing with the similar gear 24. The inner face of said. smir-gear 27 is provided with several rings of teeth 28 of differing diameters, the teeth of which rings are adapted to mesh with a pinion 29, slidably mounted upon the squared portion of a shaft 30 and having an upwardlyextending arm 31, by means of which said pinion is moved longitudinally of its shaft. The shaft 30 is rotatably mounted in two bearingbraekets 32 and 33, the former bracket being in sleeve form surrounding the stud 26" and having a bearing-socket 3 L for the forward end of said shaft 30. The sleeve portion of said bracket 32 is provided on its upper side with two cars 35, fori'ning between them the transverse groove 35, adapted to receive an oscillatory cam-wing 36, fixed with relation to an operating-arm 37. The opposite end of the shaft 30 carries a worm 38, fixed to said shaft,

and the bearing for this end of the shaft is vertically movable within a bracket 33, se-

cured to the side of the wagon-box, to withdraw said worm from engagement with the teeth of its worm-wheel, to be hereinafter described. The vertical movement of said hearing 33 is accomplished by means of an oscillatory sector 39, having an eccentric cam-slot 4L0, within which cam-slot a finger 4:1, fixed with relation to said bearing, extends. Gonnecting-r0ds 42, 43, and 44 extend from the arm 31 for the pinion 29, the operating-arm 37 for the wing-cam 36,and the oscillatory sector39 to the forward part of the wagon-body, where the connecting- rods 12 and 43 are pivotally connected to the shifting- levers 45 and 46, respectively, and the connecting-rod 4a to a crank-arm to be hereinafter described.

The apron-supperting shaft 12 at the rear end of the wagon-body carries a worm'wheel 4L7, fixed to said shaft, which worm-wheel is adapted to be engaged by the worm 38.

Rotative movement is imparted from the spur gear-wheel 23 to the spreader-cylinder 15 by a mechanism to be next described. A shaft i8 is mounted underneath the wagonbody forward of the drive-shaft 22 in rollerbearings 49, the roller-bearing 49 for one end of said shaft lying within the loop 26 of the bearing-bracket 26. The loop 26" has an internal diameter slightly greater than the outer diameter of the sleeve of the rollerbearing 19, thus permitting a slight universal movement of said roller-bearing within the loop 26. This method of supporting the bearing 49 permits it to adjust itself to any irregularities of motion of the shaft @8 due to bends in said shaft, twisting of the wagonbox, or from other causes. The shaft 4E8 carries a sprocket-wheel 50, fixed to said shaft, said. sprocket-wheel and the sprocket-wheel 16 on the spreader-cylinder shaft 15 being connected by means of the endless chain belt 19. A spurpinion 51 is loosely mounted upon the outer end of the shaft 48 adjacent to said sprocket-wheel 50, the adjacent faces of the hubs of said sprocket-wheel and said pinion being provided with engaging clutchteeth. It will be noted that the drive-shaft is located intermediate the spreader-cylinder and the shaft 18 and that the driving force exerted by the gear-wheel 23 and the resistance placed in operation upon the sprocketchain are opposed to each other, thereby relieving the bearings of the shaft 48 of the injurious pressure resulting when the sprocketshaft is intermediate the drive-shaft and the beater-cylinder. By means of this arrangement of the d riving-gear a much lighter draft of the vehicle is secured and a freedom from breakage of the bearingboxes and other parts of the mechanism obtained. The outer portion of the hub of the pinion 51 is provided with a groove 52 to receive the end of a shifting-lever 53, pivotally mounted in a bracket 5& upon the side of the wagon-body,

by means of which shifting-lever the pinion 51 is moved into and out of clutch engagement with the sprocket-wheel 50. The forward end of the shifting-lever 53 is provided with two oppositely-extending wedges 55, adapted to lie between the-fingers 56 of a longitudinally-slidable shifting rod 57, the forward end of which is pivotally connected with a crank-arm of the starting and stopping mechanism to be next described. This starting and stopping mechanism comprises a shaft 58, extending transversely of the wagon-body and supported in suitable bearings upon the forward end of said body. Upon its opposite ends are fixed crank-arms 59 and 60, pivotally connected with the connecting-rod 14 and the shifting rod 57, respectively. An operating-lever 61 is fixed upon said shaft 58 and engaged by one end of a spring 62, coiled about said shaft, the other end of said spring bearing against the forward end of the wagonbody or any other fixed member, said spring thus tending to throw said lever forward into a horizontal position. A detent-arm 63 is adapted to engage the operating-lever 61 to hold it in an upright or working position, said detent-arm being held forward to engage said operating-lever by means of a coil-spring 64. The outer end of the detent-arm is pivotally connected, by means of a link 65, with a releasing-lever 66, pivotally mounted at the sideof the wagon-body. The lower end of said releasing-lever extends into the path of the rear end of the apron 5 and is adapted to be engaged by the rear cleat 6 of said apron when the rear end of said apron reaches the forward limit of its movement.

From the foregoing it will be seen that an upward movement of the operating-lever 61 oscillates the shaft 58 and through the connecting-rod t4: connection with the sector 39 throws the worm 38 into engagement with the worm-wheel 47, also moves the shifting rod 57, oscillating the shifting-lever 53 and throwing the pinion 51 into clutch with the sprocket-wheel 50, thus traveling the apron 5 and rotating the spreader-cylinder 15.

The speed of apron travel with relation to the rotative speed of the cylinder may be changed by means of the gear-shifting levers &5 and 9L6, a movement of the latter throwing the pinion 29 out of engagement with one of the gear-rings upon the inner face of the spur-gear 27 and a movement of the lever 45 moving said pinion into coincidence with another one of said circular rows of teeth. The pinion 29' may then be thrown into engagement with said last-mentioned gear-ring by moving the lever 46 in a contrary direction.

To restore the apron to its normal forward position, Fig. 3, we have provided a mechanism to be next described. A two-part shaft 67 is mounted in suitable bearings beneath the body 1, the two parts of said shaft being connected by means of the knuckle 68. Each of the outer ends of the shaft 67 carries a bevel- pinion 69 and 70, the former meshing with the teeth of the bevel-pinion 25, fixed upon the shaft 22, and the latter with the pinion 71, slidabl y mounted upon but rotatably connected with the shaft 11 for supporting the forward end of the apron 5. A lever 72, pivoted to the forward side of the wagonbody, is adapted to move said pinion 71 lengthwise of said shaft by means of the connectingrod 73, and said pinion is held normally out of engagement with the bevel-pinion by means of a coil-spring 7 1, extending between a fixed portion of said wagon-body and the pivoted lever 72. The upper end of the lever 72 lies within a standing loop 72 on the wagon-body, and a stud 7 2", fixed to said wagon-body within said loop, holds the lever 72 against the action of its spring 74 when the pinions 70 and 71 are in mesh. To disconnect the apron from its restoring drive when said apron reaches its normalposition, a pin 75 is fixed to the end board 8 in position to engage the lever 72 when said lever is in its operative position and to push the upper end of said lever outward beyond the end of the stud 72. When this occurs, the spring 7 1 immediately shifts the lever to its inoperative position, separating the pinions 70 and 71.

In order to hold the apron 5 in a forward or normal position when the wagon is being loaded and when the spreader mechanism is not in operation, a ratchet-wheel 76 and pawl 77 are provided, said ratchet-wheel being fixed upon the outer end of the shaft 11. The pawl is pivotally mounted upon the side of the wagon-body and is pivotally connected with the crank-arm 59 by means of a link 78. It will thus be seen that when the shaft 58 is oscillated by an upward movement of the operating-lever 61 the pawl 77 is withdrawn from engagement with the teeth of the ratchet 76; but when said operating-lever is in its forward down position the pawl 77 engages the ratchet 76.

A rake 79 is mounted upon an oscillatory shaft 80, supported in brackets 81 at the rear end of the wagon-body. The shaft is provided with a downwardly-extending arm 82, by means of which the rake is moved toward or from the spreader-cylinder 15. To operate this rake from the forward end of the body 1, a connecting-rod 83 is provided, which rod is pivotally connected at its rear end to said arm 82 and at its forward end to an operating-lever 84, which lever is movable within the limits of a loop 85 and is provided with a fixed pin 86, projecting outwardly from said lever and adapted to enter either one of the openings 87 in said loop to hold the lever at one or the other extremities of its movement. A stop-arm 84, fixed to the lever 8a, lies in the path of the crank-arm 60 when the lever is in its forward or inoperative position and prevents the throwing into A drivers seat 89 is suitably supported above the forward end of the wagon-body 1n such position that the operating-levers are within easy reach of the driver.

In operation manure is loaded into the wagon-Indy, the operating-lever 61 thrown forward into its horizontal position, and the wagon drawn to the place where the manure is to be distributed upon the ground. When this place is reached, the operating-lever 61 is raised, in which position it is retained by the detent-lever 63. The upward movement of the operating-lever throws the worm 38 into engagement with the worm-wheel 47 and the clutch-pinion 51 into engagement with the sprocket-wheel 50, communicating a traveling motion to the apron 5 and a rapid rotatory motion to the distrilmting-cylinder 13. The teeth of said cylinder are normally in engagement with the manure in the wagonbody, and in starting the cylinder :1 great strain is thrown upon its driving-gear. Heretofore much difficulty has arisen in the operation of manure-spreaders owing to the frequent breaking of portions of the drivinggear for the spreadereylinder; but in the machine herein shown and described the driving strain is transmitted easily and without distortion of the parts from the tractionwheels to the spreader-cylinder. The evenness of this transmission is due largely to the fact that the downward and forward pressure of the gear 23 is balanced by the upward and rearward pull of the sprocket 50 upon the chain 19, and as a consequence power is transmitted to the spreadcr-cylinder from the tltICtiOIl\Vl100lS without undue strains upon the mechanism, obviating accidental breakage of the parts due to such strain. As the wagon is drawn forward the manure is thrown rearward by the rotating spreader-cylinder, said manure being torn into fine pieces by the teeth of said cylinder and large pieces being held in the box by means ofthe rake '79. As the portion of the apron within the body 1 travels rearward the rear end of the apron moves forward beneath the body until said rear end has been brought into contact with the releasing-lever 66, which lever when oscillated by said apron moves the detent-arm 63 by means of the link (65) connection between said releasing-lever and sa1d detent-arm and permits the operating-lever 61 to be thrown forward into a horizontal position by the action of its coil spring 62. This forward movement of the operating-lever withdraws the worm 38 from engagement with the worm wheel 47, throws the pawl 77 into engagement with the ratchet-wheel 7 6, and moves the pinion 51 from clutch engagement with the sprocket-wheel 50, stopping the rearward travel of the apron and the rotative movement of the spreadercylinder and locking the apron from further rearward movement. To restore the apron to its normal position, the lever '72 is moved from right to left with reference to the driver-,which movement of said lever places the bevel-gear 71 into mesh with the pinion 7 O,whereby the rotative motion of the two-part shaft 67 is transmitted to the forward apron-supporting shaft 11, rotating said apron-supporting shaft in a direction to restore said apron to its normal position. During this restoring travel the ratchetwheel 76 clicks under the end of the pawl 77.

To change the speed of backward movement of he apron with relation to the rotative speed of the spreader-cylinder, the pinion 29 is first moved out of engagement with the gear-rings 28 upon the side of the spur-gear 27 by throwing the lever 46 forward. A movement of the lever 45 now slides the pinion 29 upon the squared portion of the shaft 30 into coincidence with the desired one of said gear-rings 28. \Vhen the pinion 29 has been shifted into the proper position, the lever 46 is returned to its first position to move said pinion again into engagement with one of the gear-rings.

The apparatus herein shown may be changed in various ways without departing from the spirit and scope of our invention, wherefore we desire to have it understood that we do not limit ourselves to the specilic construction herein shown and described.
