MANURE-SPREADER.

SPECIFICATION forming part of Letters Patent No. 584,877, dated June 22, 1897.

Application filed March 6, 1897. Serial No. 626,289. (No model.)

To all whom it may conoerw Be it known that I, JOSEPH S. KEMP, a citizen of the United States, residing at Syracuse, in the county of Onondaga, in the State of New York, have invented a new and useful Improvementin h/Ianure-Spreaders,of which the following is a specification.

This invention relates to that class of manure-Spreaders which embody a box mounted on a wheeled frame and having a movable bottom upon which the manure is slowly carried rearwardly to a toothed beater, which removes the manure from the rear end of the body or pile and throws it rearwardly from the machine.

The invention has the object to improve the construction of such manure-spreaders in various respects.

In the accompanying drawings, consisting of four sheets, Figure l is a longitudinal sectional elevation of a manure-spreader containing my improvements. Fig. 2 is a rear View of the chain-guard and its supporting parts. Fig. 3 is a top plan view of the machine. Fig. 4 is a vertical cross-section in line 4 4, Fig. 1, looking forwardly. Fig. 5 is a vertical cross-section in line 5 5, Fig. 1, looking forwardly. Fig. 6 is a fragmentary side elevation of one of the beater-spiders and part of the beater. Fig. 7 is a cross-section in line 7 7, Fig. 6. Fig. 8 is a detached perspective view of one of the beaterlinks. Fig. 9 is a detached perspective view of the adjustingscrew of one of the upperbeater-boxes and its locking-arm. Fig. 10 is a detached perspective view of one of the links of the central bottom chain. Fig. 11 is an elevation of the righthand side of the rear portion of the machine,

showing the mechanism whereby the beater is driven from the rear axle. Fig. 12 is a horizontal section, on an enlarged scale, of the gears and clutch mechanism whereby the heater is driven from therear axle. Fig. 13 isa horizontal section of one of the hearings in which the lower beater-shaft is journaled. Fig. 14: is a horizontal section of one of the bearings of the upper beater-shaft. Fig. 15 is an elevation of the left-hand side of the rear portion of the machine, showing the mechanism whereby the movable bottom is driven from the rear axle. Fig. 1G is a detached sectional side elevation of the same mechanism on an enlarged scale. Fig. 17 is a cross-section in line 17 17, Fig. 16. Fig. 18 is a detached perspective view of the frame or housing in which the rear bearing of the worm-shaft is arranged. Fig. 19 is a fragmentary vertical section of the sprocketwheel which drives the beater, the section being taken in the plane of the wheel in line 19 19, Fig. 20. Fig. 20 is a vertical section of the same wheel and connecting parts in line 20 20, Fig. 19.

Like letters of reference refer to like parts in the several figures.

The bottom frame of the wagon-bodyis pro vided with two side sills A, connected at their front ends by a bolster or cross-piece A and near their rear ends bya cross-piece A A represents two central sills which are secured to these cross-pieces and arranged side by side at a short distance apart. These central sills project forwardly beyond the bolster A and carry at their front ends a foot-board a.

B represents the bent front axle, B the front wheels, and B the fifth-Wheel connecting the front axle with the front portion of the frame. The upper part of the fifth-wheel is secured to the underside of two longitudinal timbers b, which are arranged underneath the front portions of the central sills and connected to the under sides of the latter behind the bolster A and to the under side of the bolster and of a cross-piece 1), arranged in front of T the bolster.

0 represents the side-boards of the wagonbox, which are secured to the side sills, and O represents the movable bottom, composed of transverse slats c of usual form and provided with the usual follower c. The bottom slats are connected at the sides by the usual side links c and at the middle by a cen tral chain D. The front and rear ends of the central chain D are connected by alight chain D, forming an endless chain therewith. The chain I) runs around a sprocket-wheel d, arranged in front of the bolsterA, as usual, the upper part of the chain passing over the bolster and the lower part beneath the bolster.

E represents a movable guard-arm which is arranged underneath the lower front portion of the chain D to protect the latter against interference with the front wheels when the front axle is turned so as to bring one of the front wheels underneath the wagon-body. The guard-arm is arranged with its front portion between the longitudinal timbersb of the frame and hung with its front end to a transverse bolt 6, secured in said timbers, and is loosely supported near the rear ends of said timbers upon a transverse stop or bolt 6, as shown in Figs. 1 and 2. The rear portion of the guard-arm projects rearwardly beyond the timbers b underneath the chain and far enough to prevent the frontwheels from coming in contact with the chain. hen a front wheel is turned under the body, as indicated by the dotted lines in Fig. 1, it lifts the guardarm and the latter lifts the chain, and the guard-arm prevents contact of the wheel and chain. When the front axle is turned so as to swing the front wheel away from the guardarm, the latter drops until it again rests upon the supporting stop or bolt 6.

f represents rollers which are arranged between the central sills at suitable intervals and upon which the central chain D of the movable bottom runs. These rollers are preferably mounted loosely on cross-pinsf, which are secured in strips f fastened to the inner sides of the central sills, as shown in Fig. 4. The links of the central chain D are shown in Fig. 10 and are flat plate-links g, provided with longitudinal side flanges g. The latter depend or project downwardly on both sides of each rollerfin passing over the same, as shown in Fig. at, whereby the central chain D and the floor-slats secured thereto are centered in the body or box of the machine and prevented from running toward one side and rubbing or binding against the side.

f represents the usual rollers, which'are attached to the inner sides of the side sills and whereby the sides of the movable bottom are supported.

G represents the rear wheels, which are connected with the rear axle in any wellknown manner so as to rotate the axle.

G represents the gear-wheel which is secured to the rear axle on the inner side of the right-hand wheel, and G the pinion which is driven by the wheel G, as shown in Figs. 3, 11, and 12.

II represents the large sprocket-wheel, which is driven by the pinion G and which drives a smaller sprocket-wheel II on the lower beatenshaft h by a chain h. The large sprocket-wheel II turns loosely upon a horizontal arbor or stud 7L2, which is secured to a bearing-frame 71/3. The latter is secured to the under side of the right-hand side sill. The hub of the sprocket-wheel II is constructed with an outwardly-projecti11g cylindrical extension or sleeve 7r and is held on the stud by a guard-plate 71", secured to the end of the stud. The gear-pinion G turns upon this extension or sleeve 7L4 and is provided at its in ner side with a clutch-face h, which takes into a clutch-face 71 on the hub of the sprocket-wheel. The outer end of the pinion is constructed with an annular groove 7L8, in which the shifting lever 11 engages. The latter may be of any suitable construction and arrangement. is pivoted in front of the rear axle to a bracket 11 and operated from a front cross-shaft 11 by a rod H connected at its rear end with a slotted segment 11 at the front end of the shifting lever. In shifting the pinion for engaging its clutch-face with or disengaging it from that of the sprocketavheel the pinion moves on the sleeve and not on the stud, and when the pinion has been connected by the clutch-faces with the sprocket-wheel the latter turns by its sleeve on the stud, while the pinion has no movement on the sleeve, whereby the friction and resistance of the parts are greatly reduced.

The hub of the sprocket-wheel II is provided with an oil-cup 71., which opens by a duct into the cavity of the hub, and the stud 712 is provided 011 its upper side with a longitudinal oil-groove h This groove receives the oil at its rear end from the oil-cup and distributes the oil along the stud. The front end of this groove is open, so that a wire can be inserted into the groove through an opening it in the guard-plate 7r for cleaning the groove. The bottom of the groove is slightly raised at the front end to form a dam, which retains the oil in the groove.

The beater shown in the drawings is an endless belt or apron beater composed of upright endless chains I and transverse toothed slats I, secured thereto. The lower beatershaft 71 is provided with two spiders J and the upper beater-shaft with two similar spiders J around which the endless chains run.

The lower beater-shaft 7b is journaled in two bearings i, which are each supported by trunnions t" in two upright bars 1 Figs. 5, 13, and 15. The two uprights t on the same side of the machine are secured with their lower ends to the side sill by a cast foot The bearings of the lower beater-shaft can swivel transversely of the machine on their trunnions in accommodating themselves to the beater-shaft; but the latter is not vertically adjustable. This permits the beater to be so arranged as to run closely to the bottom and prevents the location of the lower portion of the beater with reference to the movable bottom from being disturbed.

The upper beater-shaft j is vertically adjustable for the purpose of taking up slack in the beater-chains. This upper shaft does not rotate, but is rigidly secured in bearings j, which are connected by trunnions 7 to boxes 3' arranged loosely between the upper portions of the uprights i Figs. 5, 13, and 15.

Each box 9' is guided on the uprights by side As shown in the drawings, it

flanges and is adjusted up and down by a screwjt The latter is provided at its lower end with a head 3' and works in a crOsspiecej which is secured between each pair of up rights below the box K represents a locking-arm, Figs. 9 and 11, which is applied to the head 7' of the adjusting-screw for preventing the latter from turning out of its adjusted position by the jarring of the machine. This locking-arm has two prongs 7a, which straddle one of the uprights t and an opening 7.9, through which the screw passes, and on opposite sides of said opening downwardly-projecting claws which are adapted to grasp the head of the adjustingscrew. When the locking-arm is raised above the head of the screw, as shown in 9, the screw can be turned in either direction. \Vhen the screw has been adjusted, the locking-arm is allowed to drop and then rests on the head of the screw, as shown in Fig. 11, in which position it prevents the screw from turning.

The beater-chains I are composed of platelinks l. (Shown in Fig. 8.) These links re provided with that outer sides or backs, to which the beater-slats I are bolted, and have on their inner sides, near each end, two prongs Z. The two pairs of prongs of two adjacent links engage against the rounded cross-bar Z at the outer end of each arm of the beaterspiders J J, as shown in Fig. 6, and the two prongs at the same end of a link straddle a centering-lug Z on the spider-arm, as shown in Figs. 6 and 7. The outer end of each spider-arm is provided with two of these centering-lugs, one on each side, and the beaterchains are thereby centered on the spiders. The upper spiders J turn on the fixed upper shaft 7' and are also free to move on the shaft lengthwise of the latter, so that the upper spiders can adjust themselves freely to the chains and are held in position simply by the chains.

The links of the beater-chains are made so long that each link receives a beater-slat, as shown in Figs. 1 and 6. This arrangement avoids the loose connecting-links which were heretofore used between those links which carry the slats. When such connecting-links, not provided with beater-slats, are present in the beater-chains, the chains are so flexible that the beater-slats can assume a position at a greater or less angle to the direction in which the chains and beater-teeth m move upwardly along the rear face of the body of manure in the box. The resistance which the beater teeth or pins encounter in moving upwardly along the rear face of the body of manure tends to tilt the teeth and slats downwardly and the teeth assume such downwardly-inclined position when connectinglinks without beater-slats are present in the chains. When thejteeth assume this inclined links carry beater-slats, as shown, the tendency of each slat to tilt downwardly during its upward movement is counteracted by the resistance which the adjoining beater-slats encounter and the slats are thereby prevented from tilting and kept in line with their teeth projecting squarely from the ascending portion of the beater, whereby the action of the heater is greatly improved.

N represents the spider, which is arranged at the rearend of the machine underneath the central chain D of the movable bottom and which engages with the links thereof for propelling the bottom rearwardly. This spider is secured to a transverse shaft n, which carries at the left-hand side of the machine a worm-wheel N, by which the shaft is actuated.

0 represents a gear-pinion secured to the rear axle g on the inner side of the left-hand rear wheel G, Figs. 3, 15, and 16. Ois a gearwheel which meshes with said pinion and turns loosely upon an arbor 0 secured to the frame of the machine in rear of the rear axle.

19 represents a rearwardly-ascending shaft which carries at its front end a pinion P and at its rear end aworm P. The pinion P meshes with one of several concentric gear-rims p, formed on the rear side of the gear-wheel 0, so as to be driven by the latter. One of these gear-rims is indicated by dotted lines in Fig. 15. The front end of the shaft is journaled in a bearing 19 which is hung upon the arbor 0 so that the rearend of the shaft can be lowered and raised for throwing the worm into and out of gear with the worm-wheel. The rear portion of the worm-shaftp is journaled in a bearing g, which is vertically mov-.

able in a frame or housing q, affixed to the side of the machine, Figs. 15, 16, 17, and 18. In this frame is mounted a transverse rockshaft r, which carries an elbow-lever r and an actuating-arm W. The latter is connected to an actuating-rod r leading to the front end of the machine and by which the shaft 1" can be rocked in its bearings, which are formed by recesses r in two of the Walls of the frame q. The movable bearing q is provided with an upwardly and rearwardly extending head r which overhangs the upper arm of the elbow-lever 1', while the lower arm of the lever bears upon the bearing. Upon swinging the actuating-arm r of the rockshaft forwardly the upper arm of the elbowlever raises the head r and the bearing q, connected therewith, and raises the Worm out of engagement, while by swinging the actuating-arm backwardly the lower arm of the elbow-lever depresses the bearing and throws the worm into gear. This mechanism for raising and lowering the worm-shaft is old and well known.

B represents a detent-pawl which is pivoted to the left-hand side of the machine in rear of the worm-shaft. This pawl has a depending stop-arm s, which is adapted to engage with the worm-wheel N and locks the same, and an actuating-arm s, which projects forwardly and engages in a hollow head or collar 8 secured to the rear end of the worm-shaft. Upon raising the worm-shaft the stop-arm s of the pawl is thrown into gear with the worm-wheel, and so locks the latter when the worm is out of gear, while upon lowering the rear end of the worm-shaft and throwing the worm into gear the lock-arm of the detentpawl is thrown out of engagement with the worm-wheel.
