l'o all. whom it 11m/y concern: l

Be it known that I, HENRY S. CAuPBELL,I a citizen of the United States, residing at Newark Valley, in the county of Tioga and State of New York, have invented certain new and useful Improvements in Fertilizer-Distributers, of which the following is a specification.

My present inventionrelates to fertilizer or manure distributers of the class in which the wagon-body is provided with a movable slatted bottom or carrier on which the manure is supported and by which it is carried slowly. to a rotary beater, which stirs, loosens, and delivers it to theland or to conveyers which deposit Vit on the land. 1n such machines as heretofore constructed the movement of 'the slatted conveyer y has been y automatically stopped when the load was delivered and the carrier has been returned by mechanism op-n erated by hand or by the wagon itself as it is moved forward, suitable devices being thrown into operation by the driver to cause the reverse movementof the carrier.

One object of lmyinvention is to do automatically what has heretofore been done by.

hand-viz., to cause the carrier to automatically return as soon as the load has been deliv'- ered, while the wagon is still moving forward, without any aid or attention from the driver, who can thus give his entire attentionto the team.l

My invention, furthermore, comprehends mechanism whereby the driver can by merely" shifting a lever start the beater, carrier, vand couveyer. after which he need give no further attention; to the distribution of the manure, such mechanism-being so constructed that after the load is deposited the carrier will automatically stop, automatically reverse its movement and return, and then automatically stop at the end ofthe return movement.

i The beater is of an improved construction, and it operatesin connection with endless conv veyers, on which the manure is deposited by the beater andwhichfeed it positively toward one side of the wagon'or simultaneously to op-l posite sides thereof. l

I have also provided@ shield of improved construction, which is interposed between the 4vbeater and the load of manure while the wagon .all its parts in proper position. -a leftjhand side elevation of the machine 'with L .s being loaded or driven to the field and which prevents the beater from being clogged. This shield is automatically raised when the distribution 0f the load commences, but is not fully raised until the/beater has attained considerable speed. The shield is pressed normally forward by springs which yield whenany obstruction to the free operation of the mechanism occurs and allows the shield to swing backward to relieve the strain. The arrangement is such that the shield may be lowered while the beater is revolving.

The wagon-body possesses novel features of,4

construction, as does also the running-gear. The drivers seat is so made that it may be swung forward out of the way while the wagon is being loaded, and the rear or driving wheels are so constructed that they are prevented from slipping either forward or sidewise.

Another important feature of my invention .is improved mechanism for changing the rate' PATENT OFFICE.

of feed of the manure lwithout stoppingthev l' beater. of manure delivered by the wagon tothe acre may be varied to a greater extent than with other machines of the classvheretofor'e used? By these improvements the amount f Other novel features of the invention will be -hereinafter more particularly referred'to. Yyhile the machine is especially intended to distribute manure, it may also be usedto distribute fertilizers of other kinds. 1n the fol"- lowing specification' the machine will be de-A scribed mainly as adapted for operating upon manure. s f

The distributingmachine shown in the drawings is in the former' a four-Wheel wagon that may be easily moved to and from the lield Where the manure or fertilizer is to be distributed. two side sills AUX', preferably made of channel-iron, which are connected by cross beams or sills B B2 B3 Bf B5, which are preferably of wood. Midway between the side sills the cross-sills are connected by short pieces oi2 wood C, the ends of which are tenoned into the cross-sills B', 6to., as indicated in dotted lines at in Fig. 1 and Fig. i8. The-se pieces C, Sac., are arranged a short distance apart, as illustratedin Fig. l, and they support between them,antifriction-rollers U2, over which the carriermoves. Truss-rods l, which extend under the nieces C and alongside of the sills B', cc., connect the side sills A A and are adjustably secured thereto, as indicated at a in Fig. 21. In order to iirmly connect the cross-sills to the side sills and to tighten this connection should it become loose, l em-' ploy wedge-shaped blocks E, preferably of metal and of the ltindshown in 2i and 22. These are grocved on their under sides at u and are slotted at c'. lfhey rest on top oi' the sills B', ac., and extend under the-top flanges of the side sills. lhey may be driven home with a hammer and will ser-ve to malte the structure very rigid. rihe top rails l?, which may be of wood, rest on uprights F, which in turn rest on the side sills A.' A. Rods F2, each of which is headed at its upper endif and is provided with a nutf at its 'lower end, extend through the lrails i?, side sills A- Af, Wedges E, and cross-sills B', &c.,

and firmly bind these parts together. The

sides oi' the vwagon are lined at G with sheet metal. v

The drivers seat H is secured to a curved spring z.,"\vhich is attached to a plate /',l'iinged at lf to a top cross-beam H` in such manner that the seat may be turned over forward ont of the Way While the Wagon is being loaded. The 'front axle I carries one membent, oi' a fifth-wheel. to which the tongue Iis attached, and rods l2 connect the tongue with the axle near the front wheels, as indicated in Fig. 1. Theother member, I3, of the fifth-wheel is formed Withian upwardly-extending hollow boss i', into which a king-bolt l* extends from the lower member the little-wheel. The tii'th- Wheel member i3 is connected to the wagon-body by braces or brackets Y and iw, and it is formed with rearwardly and upwardly extending braces or brackets l, which are secured to the body of the wagon and to which are also attached draft-rods Il, having adjusting-nuts if, that extend diagonally rearward and connect with bearing-brackets J, attached' to the wagon-body and through which extends the rear axle K. By this arrange- The body oi' the Wagon. comprises IOC ros

f rear ends of the wagon.

assess f rigid construction of the wagon is preserved,

and therefore there is no danger of any of the gearlng or operative connections becoming displaced.

The movable-bottom or manure-carrier L is f the same general construction as that heretofore used and is provided-with the usual follower L'. As shown, it consists of a series of parallel slats Z, attached at their opposite ends to links Z', which are hinged together at Z2,

Fig. 23,and are supported at *theirv ends on theinwardly-projecting npperanges of the side sills'' A. Midwayhetween their-ends the slats are connected to an endless chain M,

consisting of. links m, hinged together at m' 'and having' grooved Aouter siy es that fit .the rollers C2, mounted between t e longitudinal pieces C, that connect the cross-sills B' B2, 8vo.'

The slats/only cover 4about one-half ofthe chain, `which latter passes around spocket" wheels M2 M3, arranged near the front and The front sprocketwheel M2 is secured to a shaft N, which extends fro'm appoint just belowthe drivers seat to the left-hand side of the wagon, and the rear sprocket-wheel M3 is secured to a shait N', mounted in bearings in a bracket ai, secured. to the rear cross-sill B5, and another The car- The beater O consists of two end and one center disk o 0 02, connected by bars O', that the 'center disk, the inner ends ot' the bars on one side of the center disk being connected to the center disk between the ends of the bars on the opposite side.- The teeth 03 on the bars are so arranged that as the beater revolves the entire surface of manure between the inner disks is engaged by the teeth, while the teeth are separated in such manner as to prevent clogging and give perfect freedom ot' movement to the beater. In Fig. 15 i have shown a development oi' the beater, and it will be seen that the teeth o3 on succeeding bars on one side are arranged at dierent'distances from the center disk and that the teeth on the other side, while also arranged in sncceeding bars at different distances from ne center disk, are all arranged at a diierent distance from the center disk from correspond- I ing bars on the opposite side ot the disk.

The arrangement is such that the tooth of one bar acts onthe manure beside the tooth that immediately precedes it. The beater revolves in the direction indicated by the arrows in Figs. 13, 14, and 15, and it will be seen that In this 03, (see Fig. 1%) each ot which is provided with rollers om and laterally-projecting arms or lugs oi, thatext'end into sockets in the brackets P. Each ot" these brackets is firmly secured at'its lower end to one oi the side sills and extends V.up to the top oi' the wagon. Each bracket has a hinged portion p, jointedl to the body of the bracket at p' and secured in piace when closed by a screw p2. Ey the construction shown the beater-shaft may be withdrawn from its bearings by swinging outwardly and upwardly the hinged section p; The sleeves 03 are swiveled in the brackets P, giving slight freedom of movement, which willprevent undue binding or strain on thel mechanism.

In front of the beater is arranged a shield, which when the wagon is being loaded is lowered or arranged within the wagon, as indicated in Fig. 13. it prevents the manure from vlzv'eing banked up against the heater, so that when starting to distribute the manure the beater can get up a high rate of speed before it commences to act upon the manure. Thisl shield extends from one side oi the wagon to the other and is of sufficient depth to extend from the movable bottom to the top of the wagon. It is pivotally connected at its upper end by means of rods g, Fig. 17, to two vertical bars Q', `which extend through upper and lower .guides g g2, attached to the sides of the wagon. Springs Q2, attached to the rear sides oi the shield, Figs. 13 and i?, bear against the rear edges oi the upper endsv of the bars QC.' i' Normally lthe springs are relaXed, and the shield occupies the position shown inFig. 13 when it is lowered. lf,-however, when the'shield is lowered., as shown in Fig. 13, there is any pressure exerted on it, it is free to swing on its pivots q forward. When this pressure is removed, the shield swings back to the position shown by dotted lines in Figfl, but is prevented from moving farther backward by ,the springs Q2. YWhen the shield is elevated and the wagon is distributing the manure, the parts will appear as shown in Fig. 6. lf at this time any undue pressure is exerted on the shield, it is free to move about its pivots rearwardly against the pressure of the springs Q2. obstruction has passed the springs return the shield toits normal position. Aftera load has been distributed and the shield is lowered the beater is permitted to revolve by its own momentum for a time, so that while the shield is being iowered the'beater is still rotating and turning up and conveying-the manure. if this tends to impede the lowering ot the shield, the latter will swing on its pivots gin the manner before described to relieve'th` pressure. rEhe upper bearings g carry sheaves loo As soon as the Q3, over which extend wire ropes rf, that also extend through openings in the lower guides q and are attached to the bars Q at their lower ends. These ropes are connected to levers Q3" on opposite sides of the wagon, which levers are securely fastened at their lower ends to a horizontal rod R, that extends from one side ofthe wagon to the other below the uppery lap of the movable bottom or carrier L. By these devices the shield may be lowered while the beater is in motion.

@ne of the levers Q2 is connected, by means .of a rod Qt, with an arm or lever Q5, attached to a horizontal shaft S just below the drivers seat, and to which is secured aleverQ,G within convenient reach of the driver. By moving this lever forward' the levers Q3 are moved forwardly at their upper ends and cause the shield to be raised. Vvlhen the lever QG is moved rearwardly, the shield drops of its own weight. As before stated, the shield is hinged and is held by springs normally in the position shown in Fig. 6; but in the operation of the machine should the manureclog in front of the shield the latter will yield sufli- 'ciently to allow it to passand will then resume its normal position. The lower end of the shield when elevated is below the raised sidesof the wagon, (indicated at P2.) These sides are for the purpose of preventing the manure from-.falling over sidewise, while the shield prevents it from passing over the top of the removable hood T, which is applied to the rear end ol the wagon over the beater. This hood may be made in any suitable way, and it is provided with pivoted hooks t, that engage pins t' at the upper rear corners of the sides ot' ythe wagon. The lower portion lof the hood rests on a cross-piece T. By this means the beater is inclosed, and the undue scattering o" the manure is prevented. The hood is prolonged downwardly at T where it is formed into a casing for two endless conveyers T T4., which convey the manure to opposite sides of the wagon in rear thereof. The conveyers may be made of slatted aprons, as indicated., which traverse rollers mounted in frames TT. These frames are supported at ltheir inner ends on the shafts t5, which carry the sprocket-wheels TWIST. The lower rollers Ts TJ are also supported on the frames TF', and these frames carry screw-rods t, provided with nuts t7. The. rods t6 extend through curved slots s in the bach of the'hood and support the lower portions of the frames T5. By this means the conveyers may be adjusted to any desired extent. They may be arranged at an angle tocach other, so as to distribute manure in opposite directions to opposite sides of the wagon, or one of the conveyers may have its outer end elevated in such manner as to deliver onto the other conveyer, and

thus feed the manure in one direction only.

Furthermore, both of the convevers may be 'massa adjusted toany desired angle to positively feed the manure in rows any desired distance apart. `When the conveyers are adjusted to feed the fertilizer in one direction only, the chain Tl2 must oi course be made to engage the proper sides of the pinions, or the chain .must be crossed. In the drawings the parts are so adjusted that the machine -feeds to both sides of the wagon. If it is desired to have the fertilizer feed to one side only-'say the left-hand side --the apron on the 'right-,hand side should be elevated at its outer endy and the parts made'fast by the screw t7. Then the chain should be taken from the top of the right-hand center pinion T6 and made to engage the underside of this pinion. Then the aprons will both move on their upper sides in the same direction and feed lall the fertilizer to the left. 1f it is desired to feed all the Afertilizer to the right, the apron T'L should have its outer pr left-hand end elevated and made fast by the nut t7. Then the chain T12 should be made to engage the under side of the pinion T7, while the chain is also made to engage the upper part of the pinion TG. It

necessary, the links may be taken from or added to the chain, this being a common expedient.

The sprocket-wheels Ts T7 are driven by an endless chain T12, which passes around the sprocket-wheel T and over or in contact with the sprocket-wheel T7. This chain also extends around a sprocket-wheel T1 on a shaft T, mounted in suitable bearings on the righthand side of the machine and carrying a bevelpinion T2", engaging a bevel-gear T13 on a sprocket-wheel T, mounted to revolve on a stud-shaft T15, supported by a bracket T1, attached to the hood T. The sprocket-wheel T engages a sprocket-chain U, which .passes around a sprocket-wheel U' on a shaft il., to

which is'also attached a spur-wheel U2,`that meshes with a spur-wheel U;S on the beatershaft O2. The sprocket-chain U passes around a large. sprocket-wheel Us, that encircles 'a sleeveU4 on the rear axle or mainl drivingshaft K. This sprocket-wheel, as shown in Fig. 18, has a clutch member wfg, that engages a similar clutch mem-ber u1 on the sleeve U".

When the clutch members are engaged in the manner shown in Fig. 18 and the wagon is moving forward, motiop is communicated by means of the gearing described to the beater and also to the .conveyers The sprocketwheel is adapted to slide to a limited extent on the sleeve U* and it is shifted by means of a lever U5, Fig. 3, which is pivoted at if to I OO IIO

vthe side of the wagon and is provided at its frontend with a bracket a, having an elongated slot al, through which extends acranlrrod U, that is pivotally mounted in lugs u, projecting from a bracket it, attached to the side of the wagon. The upper end of the crank-rod is pivotally connected with a rod U', that is jointed at uw with the lever Q2 on the righirhend side or the machine and a short distance above the-rod The lever connected vwith the handlever Q5 iii the manner before described. lifhen the hand-lever is moved torward, the U" is operated in such manner as to cause the elntch members .ed u* to engage, and when this 'isdone the beate-r end conveyor lwill he set in motion. When the hand-lever Q5v is moved rearward, the clutch' is uncoupled from the motive 'power and' the shield is lowered; ont the beater end conveyers may convtinue to run` until their momentum is overf,

come. The sleeve Ua is connected with the driving-wheel on the right-hand side of the machine by Ineens of pavvl-and-ratchet mechf enism, such' as illustrated in Figs. 18 and 20,. lThe pewls V are carried in the enlarged outer end of the sleeve U4, and. they are adapted to engage ratchet-teeth c in the hubV' of the driving-wheel. The 'details of construction of this ratchet mechanism are 'clearly shown on the drawings. The object is to vcause the shaft K to revolve when the wagon is mov ing forward., but to prevent the shaft from revolving when the Wagon is backed.v Both. oi the driving-Whees are provided with longitudinal and transverse ribs c" e2 to give them sui'iicient-traction to prevent them from slip ping sidevvise or circnmterentially. The

l spokes 'v2 are connected' with the hub in the manner clearlv indicatedA in Figs,18 and 19.

The shaft N', heretofore referred to, .on which is mounted the 'rear sprocltetM, 'cai`- ries on its .enter 'ende bevel-gear n.2, which meshes with 'a-I'bevehpinion n3 on. a shaft n4, carrying-a' conpinion n. The pinion n2, as sho-vm'in'ig. 16nas two concentric series of teeth adapted to mesh with the pinion n3.

l The, pinion n may 'oe adjusted on the shaft n.

Vto gear with either setof teeth.

The reer end of the shaft if is supported in a bracket n, as clearly indicated in Fig. 10, and the pin- .sleeve 722 by pawl-andf-ratchet mechanism 6*,

ien is inclosed for the most part by a shell or housing n', attached to the side of the Wagon. The' cone-gear u" has three series ot' teeth u2 ngmf, all formed on the same hub, which is adapted to slide on the shaft mi. Either one of these series of teeth is adapted to engage with a worm Z1', secured, as shown in Fig. 2,' to a sleeve b2, rigidly attached to the rear axle K. This axle extends through the hub In" of the left-hand driving-Wheel, Which is of the seme construction as that on the opposite side and which is adopted to be connectedwith the similar to that shown in Figs. 18 and 19. The` axle extendsgthrough roller-bearings 7); in a bearing-.sleeve J, extending downwardly from the side sill A'. The inner end of this bearf ing-sleev J is provided with a series of inclined surfaces or teeth with which engage similar teeth b2 on a collar 5, that is free to tu-rn to a limited extent on. the axle K.. To 4 ticularly described. In the normal operation 'of the machine, however.l when the load is being distributed the shaft N' is operated, by means of the worm b' in themannerbefore described, to cause the apron or movable bottom to carry the loadtoward the beater `or distributer. The cone-pinion nrmay be lifted out of engagement with the worm Z1', so as to stop thel feed of the manure toward the distribnt'er whenever desired. For this purpose i employe bell-crank lever D2, pivoted at Z2 to the side of the wagon and having a slot cl3, throiigh which extends a hook di on ran arm d5. attached to the shaft n2. To the bellcrank lever D2 is pivotally connected a rod D,

is adapted to engage the lower'end of alever E', as shovvn'in. Fig. 6. This lever E' is pivotally .connected at e5 with the lever E2, which is pivoted at e to one of the side sills A'. The lever E' may be moved about its pivot Without moving the lever E2, and if the A'lever E' be moved rearwardly at its upper end its lower end will draw on the rod vD3 and move the heli-GraphV lever D2 downward, so as to lift the cone-gear ni out of engagement with the Worm Z2'. When this is done, the rearward movement of the movable bottom or conveyer will be stopped.. The rod D3 carries a collar cl2, between which and the guide-bracket d is interposed a spring ff", which tends to reise the bell-crank lever D2, and thus to hold the shaft nl* in its lowermost position, with the cone --gear n'ini engagement with the worm 7)'. When the lever li' is moved rearward in the manner just described, it engages a dog D5, which is, adapt- .ed to engage a toothed Wheel DG on the shaft N, to which the front sprocket-wheel M2 is attached. .In this way when the cone-gear is disengaged from the worm the further rear- Ward movement ot the movable bottom is prevented. In order to chenge the rate of feed so that any desired quantity per acre may be distributed b v the machine, l have provided devices for shifting the cone-gearn.5 either while the nf'agon is at rest or When it is in motion. For this purpose the levers E E2 are connected at e" with a rod ffl, which extends back to the gear/13 and is ..acnnected therewith in the manner indicated in Fig. 6. After the lever l' has been moved rearward Without moving the lever l'l and the cone which extends horizontallyy forward through a guide-bracket d, and at its front end itl IOO IIO

les ya gear has been litt-ed from engagement with the worm .71 and the dog U .has been made to engage the ratchet D the two levers E' E2 may be moved backward or Jforward to cause either oi' the series of wormeteeth 11g, n, or

lnwto enga-ge the worm lll. Thus three dili'erent changes oi sneed are provided which may be eected at any desired time` and inasmuch as the-pinion n3 is adjustable on the. shaft it* it may be made to engage either set of teeth 'path oie the movable bottom and against which the lower front endet the movable bottom strikesr when it has reached the limit of its movement in feeding the manure to the distributer. Une of the lingers 'w is connected by a rod vv f with a latch W5, which engages a dog' Wr" on the shaft S, to` which the arm Q5 is secured. This shaft S is encircled by a spring a, attached'to the main frame at s' and to the shaft at This spring is under tension when the manure is being` fed backward, so that when the latch iV" is withdrauui the Vshaft 'S turns to a suflicient extent to rock the shaft R through the connections betere described. This shaft l is connected onl the lett-hand side or' the wagon, Fig. 6, with a lever e5, pivoted at .s4 to the wagon and adapted to engage the collar Il on the rod D3. Vli'hen the shaft S is rocked in the manner above described, the lever s is moved forward and causes the cone-gear wfto be disengaged from its driving-worm L. In this way the rearward movement of the movable bottom L is arrested, and it is caused to reverse its movementin the following manner: 0n the shaft N is a linger w', which is connected with a rod l l", that connects with an arm fr', extending' downward from the collar The rod VW extends through an aperture in the linger w and carries on its front end a nut ai', between which and the finger is interposed a spring fr?, affording a yielding connection between the rodand linger. W'hen the shaft W' is turned by the carrier, lthe iinger w' draws on the rod W1" and turns the collar b, thus causing the sprocket C" to engage the clutch member C5, thereby causl ing" the shaft N to be driven from the axle K by means ot' the chain C'. This gives a reverse movement to the shaft br', and the vmovable bottom is caused. to travel in a removement, at which time its upper `front end f engages the lever Wg and causes it to with draw the rod W2 from the linger w', and thus the clutch at C5 will be'uncoupled and the movement of the movable bottom will be an rested. lt will thus be seen that after the machine is once set into operation the load will be delivered automatically, 'and after it is delivered the movable bottom will be automatically returned to its closed position and will then autou'iatically stop without any attention' whatever from the d river. It at any time the driver wishes to arrest the return movement of the carrier, he can do so b v kicking forward the footlever VW. This will release the finger Iw and the clutch at C will un couple, the gearing' for the rearward movement of the carrierbeing` still uncoupled, inasmuch as the dog' l' I would be in the position indicated by dotted lines in Fig. 26, and the shaft S will hold the parts connected therewith in such a position as to uncouple the driving mechanism. The driver can, however, cause the return movement of the carrier to be continued by placing his foot on the rod W7, which is normally held up by a spring in and which is pivotally connected with the latch VV. Such a movement will cause the shaft l to be turned and the finger w to be engaoed bythe' rod 72 inthe manner indicated in Fig. 24, whenthe return movement et' the carrier or movable bottom will be resumed, and it will be automatically stopped by the foot-lever W3 at the proper time in the manner before described. In like manner the rearward or feed movement of the carrier may be arrested at any time by means ot the lever E'. The rearward orl feed movement ot'V the bottom may also be stopped by the rod i' f", as it will be seen that itr the parts are in the position shown by full lines in Fig. 26 the driver may b v depressing the rod N7 disengage the dog W, and the shaft S will be turned by the spring s in such manner as to cause the driving mechanism tobe uncoupled. lt will thus be observed that the movements ot' the machine are under perfect and easy control of the driver. `When arriving` at the field with a load, by shoving; forward the lever Q the driver au tomatieally throws into gear the shielddifting devices, the beater-operating' mechanism, the conveyor-actuating devices, and the mechanism for actuating the movable bottom or carrier. .if desired, the entire load may then be deposited, and as soon as this is donethe feed` -roo IIO

at anytime wishes to discontinue the feed of the manure, he can doso in an obvious way by mea-ns of the lever E or the rod W7. v1n like manner he can, if desired, arrest the return movement of the movable bottom by means of thefoot-.leverVV3 and can then cause the reverse movement to vbe continued by ing the lever E and then operating the lever E2. It will thus be seen that the mechanism willoperate efficiently and automatically to a. 'large'extent,"leaving the driver'y to give his entire attention tothe team. The mechanism whichfl employ for effecting these automatic actions, while apparently somewhat complicated are, in fact, simple in construction and Operation andwork positively and satisfactorily at all times. v l
