Application filed January 9, 1907. Serial No. 351,4;13..

To all whom it may concern:

Be it known that I, JOHN L. BARKER, of Racine, Wisconsin, have invented a Manure- Spreader, of which the following is a specification.

My invention relates to Vimprovements 1n that type oi' manure-spreaders, comprising a wagon-box for holding the manure to be dis-4 tributed, which is provided with an endless carrier traversing its entire length, means for propelling said carrier in such a manner as to convey the manure slowly toward the rear end of the beater, and a distributing mechanism at the-rear end which raises the manure from the carrier, and scatters it upon .the ground;

The principal objects of my invention are: first, to provide a movable wagon-box which can be readily lifted oil` the running-gear, in order that the latter may be used for other purposes when not in use as a manurespreader second, to provide one or more endless carriers for delivering the manure to the beater, lwith means for driving them continuously in one direction, and thereby avoid the vnecessity ol' reversing the direction of travel of the carriers, in order to return them to their original position for loading after the load has been removed; third, to construct and operate the aforesaid carriers, so that they wi l pass over both the front and rear bolsters of the running-gear, whereby theydo not interfere with the reach and the latter may be retained in the running-gear, which is impossible Where the carrier or its equivalent passes below the .rear -.bolster; fourth, to so construct and operate the cari riers that they will operate freely at all times in their passage over the bolster without beingobstructe box when heavily loaded or by the warping, twisting, or Winding of the slats ofthe carrier; fifth, to providea shield in connection with the beater or distributor at the rear of the Wagon-box, and so construct said shield `that it will prevent the manure from coming into direct contactwith the beater, so lon as the carriers are stationary, but which wi bevraised automatically from its p osition in front of the beater when the carriers are started, thereby permitting the materialto be brought into contact `with the beater, and 'which Will also fall automatically as the last pf the load approaches the beater,so as to by the sagging of the Wagon- I hold the very last of the load, thereagainst, and cause it to be carried out of the box, thereby avoiding the necessity of a traveling end-gate, which has heretofore been used to accomplish this result sixth, to provide a spring-comb or rake, operatingin'conjunction with the beater, and constructed to open and permit obstructionssuch as sticks or stones to pass through, without at'the saine time opening across the entire beater and thereby momentarily ceasing Ato operate at points where there is -no obstruction; seventh, to construct alateral distributing device, which will sc tter the material in a lateral `direction beyond the sides of the wagon-box, and thus allow-a wagon-box of ordinary Width set in an ordinary running-gear to serve the saine purpose as the eXtra-Wide box and consequent special running gear which have heretofore been in use,`this having the further advantage of reducing the number of wheel tracks in covering the round, which is an essential object in so t ground, such as meadow-land; eighth, to construct a driving mechanism having a variable speed-con nection, operated by the driver of the spreader, whereby the speedof the carrier or carriers Ais varied, so as to vary the rate at which the manure is distributed, and further, means for starting and stopping the beater independently of the carrier.

For the better understanding of my invention, I have illustrated my spreader in the accompanying drawings, wherein `Figure 1 is a side elevation of the spreader from the vleft side, the front wheels and running-gear being omitted for clearness sake;-

Fig. 2 is a plan view of the same, parts being broken away; Fig. 3 is a side elevation of the same from the rlght side; Fig. l is a longitudinal section through the s reader, slightly on one side of the' center ine; Fig. 5 is a transverse section looking toward the rear; Fi s. 6, 7 and 8 are respectively a front View, sioeelevation and plan view 0f the beater driving-gearing and clutch; Figs. 9 and 10 are respectively a fronteleyation and aplan,

partly 1n llon itudinal section, of the drivinggearlng for t e pushing-devices; Fig. 11 is a.

perspective view of the hub-portions of .the 4 same; Fig. 12 isa view from the rear of the opening-rake one end of t' e same on an enlarged scale;

Fig. 13 is a similar view' of Fig. 14 isa plan of the stepped bar for the 30 mounted a transverse shaft 33, which carries blocks 22, at the front end, at the rear end. Eachof these sill-blocks is 'enable this to take place,

lateraldistributincf mechanism; Fie. 15 is a perspective view of the rear central sill-block, showing the guides for tne carriers.

In these drawings, every reference .character refers always to the same part.

The drawings, Figs. l, 2, 3, and 4, show a box wagon-body 21, which is of lthe same width as an ordinary farm wagon-box, and is designed to lit onto an ordinary farmwagon running-gear,I said wagon-body comprismg a bottom 30, side-pieces 31, and a front or dash-board 32a. ,The real'end is left open, and has the beater and distributing meehanism'located therein, as will be hereinafter described. The body 21 is supported'and braced by the usual girth -strips 29, and bracing arrangements 32; but the girthstrips 29 at the ends of the body, instead of being close to the bottom thereof, are spaced apart therefron by the interposition of silland 23 and 23a notched asshown at 24 on its under side to receive the bolster of the running-gear. There are three blocks 2,2, one central and one Vat each side, and two side blocks 23, while the central rear block, being somewhat differently formed from the side blocks, is

- designated 23a.

At the rear end of the wagon-body 21 is four sprocket-wheels 34 keyed thereto along its length, and a worm-wheel'35 at the righthand end thereof; and at the front end is similarly mounted a transverse shaft 36 which carries four `flanged idle-pulleys o1'A rolls 37, these pulleys lymg in line with the several sprocket-wheels 34. lhese pulleys and wheels form mountings for the carriers, which are herein two in number, each consisting of a pair of sprocket-chains 38, crossconnected by floats or wooden bars 39, the latter being arranged to slide along the bot-- tom 3() of the wagon-body when in operation, and in so doing to push the manure toward the rear. The shaft 33 acts as the drivingshaft, the sprocket-wheels 34 engaging with the links of the carrier-chains; and to maintain the proper tension, the shaft 36 is journaled in blocks 136 sliding in franies 137 on the side-pieces 31, and provided with screws 1 33 whereby the blocks 136 are drawn forward to tighten the chains 38. lReturning, the carriers pass over the running gear an( close to the bottom 3() of the wagon-body, and to the end glrths 29 are set apart at a distance below the bottom board, as aforesaid. The general arran ement of the carriers is clearly seen from Fig. 4. 'lo lift the carriers clear over the holsters 'and girths 29, l provide the rear sill-blocks rounded at its ends, and the center sill-block 23a has two such beads 40, one' on each side,

, su'ch l the hind-wheels 25 of the wagon.

for the central chains of the carriers, while the carriers are supported between the endgirths 29 by two pairs of metal straps 41, which form slide-ways for the floats 3.9, and their arrangement in transverse section is 'clearly shown by Fig. 5. It has been found unnecessary to provide any beads 40 on the front sill-blocks 22, and therefore such are not shown. The drive-shaft 33 is also supported in the center against the bending momentbrought thereon by a journal-block 42. Along the center of the wagon and at each side'are'mounted shield- plates 43 and 44, which'eover the chains and reventthem from becoming clogged vwith ertilizer, and these plates are pitched obliquely, as shown in Fig. 5, `whereby the material is caused to slide down on to the bottom of the wagon where it will be reached by the bars 39'.`

Althoughmy invention is not necessarilyl confined to the use of'double carriers, I deem construction an important feature thereofA The advanta es gained thereby are principally as follows: lVhen only two chains are used, the floats are so long that they are liable to warp, twist, or bend to such a degree that they will not easily pass around the ends of the wagon-box, and more particularly,

they will not pass between the wagon-bolster and the body, unless the latter is raised very much higher than would be desirable, since this would involve increased labor in loading. The ,liability of a single carrier to -be obstructed in its passage over the bolster, would also be augmented by the tendency of the bottom of the wagon-body to sag in the middle when loaded, as the support of the girth 29 is removed therefrom; but the arrangement of the two carriers not only overcomes these diflieulties, but enables the bottom 3() to be supported at the center by means of the block 23, and moreover the slats being I less than one-half as long, may now be very much lighter to provide the same strength, each slat having to do only half the work that a single long slat would. do. Moreover, the load of the wagon is more evenly divided between the two sides by-mcans of the central double-pitched shield-plate 43.

All 4the mechanism connected with my manure-spreader, is operated and set in motion by means of a shaft 28 mounted transverselybelow the waren-body and at the' center thereof, and said:q shaft itself driven by means of gearing connecting it with each of The hindwheels are provided with sprocket-wheels 26 secured to their hubs, while the shaft 28 has on each end a sprocket-wheel 45, which is connected to its respective wheel 26 by a vchain 27. The sprocket-wheels 45 are not keyed to the shaft 28, but are operatively 'connected therewith through a pair of ratchetwheels 46, which, are keyed to said shalt, and each wheel 45 has on its face a pau'l 47 which is pressed into engagement with the teeth of one of the wheels 46 by'means of wheels independent of each other in cases where one turns'faster than the other, as in `turning a corner. 'Each'sprocket-wheel 45 is preferably provided with a cylindrical guard-flange 49, within which the ratchetwheel 461ies, and which acts tofprevent manure from falling thereon and clogging its action'.

At the open rear-end of the wagon-body 21 is mounted a beater-drum 50, -said drum consisting of a pairv of end-plates connected by bars 51, in which are set beater-teethl 52,

which in the revolution of said beater engage the manure and carry it upward over the top thereof, as seen in Fig. 1. This `beater is journaled on atpair of rearwardly projecting arms 58, which are secured to the sides 31 of the wagon-body, and connected together at their free ends by 'a beam 53a. The beater is driven from the shaft 28 through gearing, which will be presently described.

The driving-gearing for `the carriers and that for the beater-drum 50 are independent of each other, the former being on the righthand and the latter Aon the left-hand end lof the shaft. -The.driving-gearing for the chains comprises a bevel-gear-plate 54, carrying three-rows of teeth 55, 56 andl 57 one within the other, and each of which is adapted tomesh with the teeth of a bevel-pinion 58, which is keyed in a slidable manner by a spline 59 to a longitudinal shaft 60, which turns in a bearing-block 61 and projects into a bearing-lug 62 formed on a yoke-piece, which also carries ahub 6.4 to receive the hollow journal 66 of the gear-plate 54 which Y slides on the shaft 28. The bevel-pinion 58 may slide forward 4or backward to engage i so ' set ofte'eth on the plate 54 to another, the

moving it endwiseI rin-the shaft 28 vthe pinion. The plate 54-is lkeyed nonrota- Y spline 67, and in-order to provide wise movement any one of the three series of gear-teeth on the plate 54, and it will be of course underf stoodthat these teeth cannot be cut With -mathematical exactness so that each set-will` fit the bevel-pinion, but the action will besufliciently precise for the purposev at hand.-

In order tov disconnect the gearing of the driving-shaft 33, and also to change from one plate 54 is separated from the pinion 58 by away from tably on the shaft 28 by means of a key or foi-the endof the plate 54 uponthe shaft 28, there is provided a -yoke 68, whose ends vare on `oppositejsides ofthe plate and are provided with Vobliquecani- lugs 69 and 70, the formeron the outside and the latter on the inside of the gear-plate. The camlugs 69 are two in number, and coperate with similarly shaped oblique surfacesjl on the hub 64.; while the oblique-edged lugs'70 short shaft 88, one end of which pinion 58 and no longer to mesh therewith,

and when in this position the pinion 58 can be shifted so as to mesh with any of the three sets of gear- teeth 55, 56, or 57 when the plate 54 is moved forward again.

The end of the yoke 68 is connected by a bolt 7 4 to a hand-lever 7 5 by an intermediate link 7 6, the hand-lever being mounted on 'a pivot 77 at the front end of the wagon, and having a bolt-rod 78 engaging in a notched quadrant 80"* and operated by a finger-lever 7 9sv The notched quadrant 89Et in which the bolt-rod 78 engages is immediately behind the quadrant 8O for the hand-lever 81, which is mounted on the same pivot and has a boltrod 82 operated by a finger-lever 83 and engaging in the notchesof the said quadrant 80, this latter lever being for the purpose of operating the pinion 58 to shift it longitudinally in order to change the rate of distribution of the fertilizer. The lever 81 has a depending end`81, which is connected by a shiftin -rod 822r with'a collar 84, turning between anges 85 on the periphery of the pinion 58, so thatthe inion may be shifted by the turning of the ever 81 without interfering with its rotation. The worm shaf-t() hason itsrear end a worm 86 turning in a frame 87 and engaging'the teeth of the worm .85, which is also journaled in the frame 87. The beater drum 502rotates in a direction opposite to that of the rear wheels and the s aft 28,v and it is therefore necessary to provide means for reversing its direction. The said means, -as herein shown, comprises a in a bearing plate 88a on the side 31 of the wagon-body, and the other end in a yoke 89 also mounted on the side 31. The shaft 88 carries a loose gear-wheel 90, which meshes with a gear 91jkeyed to the .shaft 28, and rotating therewith. A s rocket-wheel 92 is loosely mounted on sai stub-shaft and is connected by, a driving-chain 93 with a' sprocket-wheel 94 on the shaft of the beater. The sprocket-wheel 92 is arranged to be clutched and driven by the wheel 90, there being interlocking-clutchseth 95 on the hubs of the two wheels, and the wheel has anendwise movement on the shaft toward `and from the wheel .92'to engage' and disengage it therewith. To effect this movement, the hub of the wheel 90 has'on its inner side a pair of anges 9'6, which are engaged is journaled by a fork 97 on the end of a lever 98, which is fulcrumed at 99 to ears 100 on the side of the wagon-body. The said lever 9S is provided at an'interinediate point with an eye 101 through which passes a shifting-rod 102, said shifting-rod having an oblique ol'l'set 103 (Fig. 8) which lies between a pair 'of guidebloeks 104 on opposite sides of said leve-r 101. When the rod 102 is shifted endwise, the ottlA set-103, in passing through the eye 101 ot the shifting-lever 08, moves it in one direction or the other, as indicated by the dotted and lullline position in F ig. 7, so as to move the wheel 90 endwise on its shaft and engage or disengage the sprocket-wheel 92. The endwisc movement of the rod 102 is effected by a lever 105 pivoted on a fulcriun or pin 105il at the front end of the wagon, and with which the end of the rod 102 is connected, and. said lever is preferably provided with the usual locking-bolt 10G, finger-lever 107 and quadrant 10S, whereby iat is held in the position to which it is set. i

",l`he bracket-arms 53, which suppert the beater-drum 50, are prolonged to the rear ol said drum, and connected by a cross-beam 53, and carry the late-ral distributing-device. rl`his devicecomprises a-yoke 100, which may be an angle-iron -bar havin r its ends bent y I* vertically and secured t'o the ends ol the arms 53. Alongthe `center of this yoke. are-attached a plurality ol distributing-bars 110, which are. pivoted .on pivotfbolts 111. A stepped cross-beam'112, thel form ol' which is best shown in Fig. 14, is laid across the whole series ol" bars 110 at the rear thereof, and ,is pivotally secured to each bar by-,means ol a bolt 113, the arrangement being such that the beam 11'2 oscillatcs l'reely with the dis` tributing-bars 110 in a horizontal direction. On thelel't-haml arm 525 is pivoted a belleranklever 114, one arm oll which is connected by a link 1 15 to the center ol' the beam 112 while the other arm has a ball-andsocket joint connection 110 with a pitman 117, whose other end is connected' also by a ball-am1-socket jointwith an eccentric' pin 118 on'the sprmket-wluel 04.

'lhe arrangement is such that the rotation of the sprocket-,wlleel 04 causes the oscilla- 'tion of the bell-crank lever l 14, and hence oll the distributing-bals 110, which oscillate rapidlyl from side. to side as the manure is thrown over them by the. beater in its revolution, and thus cause it to beseattered laterally over a suitable width ol' ground. lhe stepped arrangement of the distributing-l)ars is such that any manure falling on them is thrown outwardly from the central bar to-` wards the outer bars on both sides,

The spreader, as thus l'ar described, is sul"- licientl)y complete l'or practical use, but in some cases l may also use a lurther device, thefpurpose ol' wlnch is to prevent the Inanure from engaging and resting upon the' beater-drum before the latter has begunto revolve; to prevent said manure from falling out of the rear of the wagon while being brought to the place of distribution; and further to hold the last of the load against the beater. This device comprises a hood 119 (omitted from Figs. 2 and '5) which is in the forinof a cylindrical segment and mounted on radial'arins 120 oscillating about the shaft of the beater. The upperpart of the arm 12() on each side is connected to a post 121 at the side of the wagon by means of a pair of jointed bars 123, 124 conneeted'together by a pin 125. Each bar 1 23 has a laterally projecting pin 126 which isaeted on by a spring 127 to draw it downwardly, this spring being of any preferred foi-1n, and herein shown as a coiled tension' spring having one end fixed to a pin 128 at the side of the wagon. The action of the spring is to draw the jointed rod 123, 124 downwardly, pulling the hoed 1 1-9 forwardly and `downward ly into the position shown in Fig. 4, so that it closes the end 'of the wagon and'cuts oil the manure therein from the beater, when the latter is not in action. W hen the beater and carriers are started up, the hood 119 thrown up into the position shown in Fig. 3, and this is caused t'o take place by means ol a board or plate A140, which is vattached to the arms 123 in the position shown (see Figs. 3 and 4) ex* tendingr across the wagon-body in a position to be pressed upon by the manure as soon as it starts to move rearwardly, and the pressure, ot the manure on it. holds it in the raised position as long as there is any manure in the wagon. .\s the last ol the load passes over the. board |40 thc hood drops and holds the remnant ol' manure up against the beater to enable it to be properlyy distributed by the latter.

ln order to break up the manure, 'l provide on the rea r edge ol the hood a comb or rake, which is divided into two or more sections designated 120. .llach section is' secured to a cross-piece. 130 carried by the arms 120 and is hinged thereto b r a. common spring-hinge 131 having a torsion-spring132onthepintle thereol', the action ol' which is to turn the comb sections into the extruded. position. As the manure is carried over by the heaterteeth. it strikes the comb-teeth andis opened out and separated, and by dividing the comb into several sections l gain the advantage olf haring each portion olf the circnml'erem-o acted on by its own comb, whereby any large. clod would not raise the entire comb and thus allow pieces to get through without being properly opened. While l do not'. con- `Saler this arrangementa necessary element oliemy spreader, 1t 1s an advantageous addition thereto.

To prevent manure from Falling over the sides ofthe wagon-body when carried up by the drum, I provide a pair of extension gu s rds fertilizer-movin H1`33 at the rear end of the sides 31, and other guard-plates or shields 134 are set along the sides to prevent manure from falling upon the gearing. f

Vi hile l have hereinabove described the preferred form of my invention, l Wish it understood that 1 do not limit myself to any one of the particular features thereof, and I fully realize that it is capableof numerous modliications Without departing from the principle thereof, and l consider such modifications and any omissions may be made Without departing from the principle of my invention.
