Reterring nowy more partie-ularly to Fig; l,y there i's illustrated at numeral' l the bed of a Wagon or truck,T to the overll:ingingrearend of which is aliXed, by means of'al suitable angle iron 3 (or otherwise), ay verticali support 2; The supportisin the form ot' a board and extends over substantially theentire Width ot the bedl'and'hasmountedltheref on by means of suitable brackets 40' a substantially cylindrical' hopper 4.V The bracket-s4'O are cut and bent from the hopper 4, forming an integral part thereof;i u

Thehopper 4 includes al bottom orbearresponding.y "parts throughout the several V'port materiali as does a suplporting disc 14 (tovbe described). The false ottom 6 issolid, v except for two opposite peripheral openings 7 'which are positioned' at ninety degrees with respect to two oppostely located: chutes 8on and communieatingv with the hopper; 4 (see Figs. 4, 5 and It `Willbe noted that this false bottom 6, is solid', except' :tor the openings 7 "located in a pivedetermined relation with respect'to certain regulators and diverters (4to be more particularly described); but the primary feature is a cover over the regulators and diverters to confine the materiall Withinv a tunnel While bei'ngmeasured' and diverted tothe Chutes.

A vertical mainshaft 9 passes through the bottomsr 5 and 6; by Way of suitable bearings 41, and' 42 respeGt-,Vely,said shaft 9 beingl rotatable in said bearings. Mounted on this shaft 9 andy rotatable.therewith are several elements, comprising lirst, anV agitator l0 (sho-Wn in plan in Fig.' 7'), said agitator 10 comprising an outer ring 111 supported' by paddle shaped! radial ribs l2 for agitation and scrapingpurposesand a screen 13 mount#- edi on the ribs or spider 12l for moyement therewith and for the purpose ofl sifting ing support 5, abovewhich is mounted ay u i fertilizer or the like which is positioned in the hopper 4.

Second, there is mounted on said shaft 9 and between the bottoms 5 and 6, a rotatable material supporting disc or memrsl ber 14 having an y upwardly projecting with respect to the member 14. For instance,

it may be located in the alternate position indicated by dotted lines A in Fig. 4. Inl any instance, it isipreferable that lthe rib be sufficiently deep that the distance between the rotatable support, and the false bottom,

be equal toor greater than the radial width of said opening 7, f .Y v

Third, Ybelow the bottom 5 there is provided on the shaft 9 anintegrally rotatable nest ofgears 43 and 44 which are adapted to be shifted vlengthwise of thevshaft 9 'sorthat the gear 44 of the nest may be made to mesh with a gear 45 of another'integrally rotatable nest of gears,'or the ygear 43 may meshwith gear v46 of said last-named nest. By Vthis means the gear or velocity ratio between the shaftv 9 and its driving shaft 4 7, `and thus its ratio to ground 'travel correspondingly, may be changed at any time conditions may require.

The nest of gears 45, 46 are mounted on the counter shaft 47 which is geared to a jack shaft 48 by way of a set of bevel gears 49. It

will be seen from Fig. 1 that the jack shaft is supported from the rear end of the bed 1 and is driven by way of a sprocket 52 and chain 49 from a sprocket 50 mounted so as to be movable with one of the rear wheels 51 of the truck or wagon and the ratio of revolutions of the shaft 9 to the ground travel may be further changed by -a change in the ratio of sprockets 50 Aand 52. The chain drive comprises a mechanical connection between the wheel 51 and the main shaft 9. Hence it will be seen that the rate of rotation of the jack shaft 48 is proportional tothe angular movement of wheelV 51 which in turn is proportional to the movement of the vehicle.

As indicated in Fig. 4, the jack shaft 48 is geared with two vertical shafts 53 and 54 by way of bevel gearsets 55 and 56 respectively. Itis to be understood that the various shafts herein described are suitably mounted in bearings associated either with the stationary hopper 4 and or the support 2. Y f Y At the lower ends of the shafts 53 and 54 are fastened rotatable broadcasting discs 1? on the upper surfaces of which are aiiixed dial fins 57 (see Figs. 3 and 4). From 4 it'will be seen that the said chutes 8 extend 'positioned'sidewardly on the hopper 4 and ses Y communicate therewith by means of ports 58 illustrated in Fig. 4. From the above it will be seen that any fertilizer or the like which descends withinV the chutes 8 falls upon the rotating broadcasting discs and is thrown off through theports and into .the chutes. ThisY is because the diverters Icompletely close the spaceor tunnel between the" false bottom', the horizontal face of the material carrying'disc and the' internal rib 15. 'It will be seen howl ever that the diverters willonlybe op'en upon counter-clockwiserotation ofthe disc 14 and that if saidldisc 14 isrotatedin the reverse 'direction that thematerial on the edge thereof will automatically close the diverters so thatno material is allowedjtopa'ss through Y the ports butv is allowedfto pass uninterruptedly in reverse direction through theV tunnel. It will be note'dthat the diverters are on the receding sides ofthe chutes 8.l

It is understood 'that the counter-clockwise movement for deliveryjis only a matter of design and that by changinof the position of the gears the machine'maybe constructed to revolve in a clockwise direction. Under such conditions the relativepositi'ons of the divertersand regulators will also be reversed. On the approach sides of the chutes 8 are provided pivoted gate valves ,or regulators 2l) which slide into and out of the 'hopper 4 and between the two members 6 and14 at their edges. They be adjusted toincrease or decrease the openings through which the fortilizer mustpassin order to getto the chutes. These regulators 20 which slide into and out of the hopper 4, virtually filling thevertical distance betweenmembers'iand 14, are held in position by cotter pins A61 'l which pass through any one of a number of fopenings formed through an arcuate shaped piece 21 attached to the hopper 4.k It is apparent that by provioing a holding means for therdiverters 19,l that theyalso may be used for regulating the quantity of fertilizerpassing to the chutes, that is; by predeterminately positioning them angularly. Alternate, dotted line positions show `the closed positions of the diverters19 and regulators 2O in Fig.

It is to be understood that the outlines of the diverters and regulators are substantially thatv vof the space ortunnel between the disc 14,' false bottom 6 and rib '15; If the rib is natation' other. than the shapesy describeththen the ends of' the diverters and regulators should con form thereto.

The operation of the! device is ars follows A charge of fertilizer is carried in the hop.-` per 4 which is replenished from time to time from a main supply on the, bed ofthe wagen wzor truck. As the truck nieves forwardly, the lo wheel 51 rotates at a proportionate rate of Aat `disc 1d and the rib 15 speed and rotates the sproc-lret a9. so that the sprocket 52 on the iaek shaft 48 is rotated proportionately by way ofthe chain 49;. This Aresults in proportionaterotation of the yvertilcal feed shaft 9: and the shafts and associated with the. broadcasting. discs 17. 1

The material in the hopper 4r falls through the rotating screen 134 und Spider l2. As it xsifts down on tol vthe false bottom Ei it is "forced by the scrape-rs around into the openings 7, from whence it drops to the rotating disc 1d and into the open tunnel formed by the side of the hopper Li, the` upper face of and is thus positioned peripherally on the rotating disc lei.

Forward movement of the vehicle is adapt-- ed to elfect counter-clockwise rotation of the disc 14 and associated parts, as will be apparent by tracing action of the gear train in the drawings. This counter-clockwise movement causes the material to get in behind the diverters 19 and push them to their full open position so that the material is diverted V,through the openings 58, and into the chutes 8, from whence it descends dow-n on to the broadcasting discs to be projectedcentrifugally to the ground. It is to, be understood that the regulators 20 may be set at any voptimum position for effecting passage of i scribed above.

'any predetermined amount ofmaterial.

The counter-clockwise movement causes the material, through the frictional action of disc 14 and rib l5 to be carried under the solid portion ofthe false bottoni 6 and thus is con- 4fined and is under pressure as it reaches the opening-between regulator 59.l and rib 15. After passing through this pre-regulated opening it` gets behind the diverters as de- `springs may be provided to insure complete contact of diverter with rib l5.

As illustrated in Fig. 4:, the upper ends of the chutes 8 are open so that the amount and grade of material passing downl the same may be examined at alltimes. By this means a close check may be kept upontthe satisfactory operation ofthe machine by the man who fillsv the hopper.

As can be seen from the drawings, the aneogular velocities of the broadcasting discs are considerably higher than the angular velocity of the delivery disc 14 and associated parts (note the relative gear diameters).

When the truclg or` the like is reversed in direction 0f movement, the disc; 14. and: all

It is to be understood thatl other parts reversey in direction; of movement., The` direct consequence is that any material which is then at the periphery of disc 1111:` will close the diverters or defiectors 19. that no spreading action is eiected. 1 It will be seen that under normal conditions of opfA eratiom that is, when the disc 14 is movingY counter-clockwise. (Fig. 5);, that the eifeet of the friction between disc 14 and rib 15, and the material in the tunneiv is to till the tunnel space between the support 14, false bettom 6 and rib 15 so that there is provided effect a substantially constant pressure feed of material into the chutes 8. Ijt is to be understood that the openings are suiiicient- ,ly large, and/or the tunnel size sufficiently.

small, to provide, during counterclockwise rotation of said support, for the iilling. with material from the openings 7, of those porf tions of the tunnel between each opening 'Z and its. respective delivery chute. 8. In other words, the` diver-ters 19 and/or regulators 2Q are eective as throttles and the frictional action'of the disc 14 and rib 15 maintains material piled up against them at all times. Hence ycompensation is provided for yany irregular sifting action through the screenA 13 due to irregulark feeding of the machineby itsoperator. K

lt is to be understood that althoughl have shown a construction wherein twochutes and associated broadcasting discs are. used,- that nevertheless a greater plurality *or` only one set of these may be used. The chute y or chutes may also be placed in a position other than shown. In any event, it is preferable that the opening or openings 7 in the false bottoni be arranged in staggered relationship With respect to the chute or chutes 8 and attendant diverters and regulators. Thempurpose of this is to provide uninterruptedly the improved pressure action. It will not be interfered with by material coming in over said diverters and regulators.

It will be clear that the connections between the main shaft 9 and the members carv ried thereby may be made by set screws, keying, crown coupling, socketing or otherwise.

In view of the above, it will be seen that the several objects of the invention are achieved and other advantageous results at tained.
