bodies or has associated therewith screening means, for separating the dirt, leaves or other refuse from Vthe beets propel' as delivered .to the railroad beet car, the refuse being collected in a tare receptacle or chuteV lfor redeliveryj to thesame aforesaid wagon for reweighing to determine the tare to be deducted, from the initiallyy weighed '-load, and hence the actual weight of the beets to be accounted for. f j

rVariousl types of beet Vdump apparatus have beenfemployedy to accomplish the foregoing general aims, and I am aware of the y' factthat some of such structures'embody a main inclined endless conveyer discharging to an auxiliary endless screening conveyor, ,adapted to be conjointly disposedat substantially `rightangles to; the railroad trackage, whileV others embody a main inclined conveyor discharging into aV rotary cylindrical screen, adapted to be conjointly disposed substantiallyV parallel of the railroad trackage, the screen deli-veringthe vrefuse to a tare receptacle underneath the same', and the y apparatus providing for means `to discharge the beets fromthe outer end of said screen laterally t` c wardsy said trackage. v f

In these-forms of apparatus, however, al-

though in one sensev they` may be termed ,a

i parallel type of station, they are not of vthe Y same parallel system of layout as will hereinafter be disclosed; As a matter of fact they so obstruct the space adjoining the railroad trackage as to make itV impracticable to maintain a substantially straight team driveway approximately'parallel to the rail-V road track between the receiving beet hopper and the tare receptacle, which arrangement broadly and specifically, according to my improvements, not only provides for substantial economy,from several aspects, but is also eminently desirable for teaming or trucking purposes,` The beethopper of such formerapparatus is located on the offside of the linclined conveyer, lthe, conveying furthermore these hoppers are disposed asa bodily whole substantially abovethe ground level, which necessitates the construction of .means proper kbeing disposed between s the hopper and the railroad trackage,A and 60 a team' driveway, embodying an elevated platform having reverselyl disposed ramps,k as well as a hoisting .framework for, dumpwhich not only-adds, greatly to installation costs but alsofremains in the nature yofi a. f v

permanent structure, whereas the remaining apparatus. is now generally constructed 'as portable units,v so4 that .if that `particular dump station is to'be abandoned forV an- Y other.' location, or is to lremainlidle. for any other reasons, it becomesnecessary to separately build up `anotherhopper, elevated wagon driveway and hoisting framework, at f .each location where the portable units ofthe apparatus areto be used'.

One of the primary objects of'mylimproveniente, therefore, has been to i devise lsucha parallel layout type of beet dump station that theteam driveway on theregular railroad :right-of-way will noty be impaired v or obstructedby the installation of the station, and will serve also asgthe station drive,-

.way between the inclinedconveyer and the railroad track,for alongithe lnearside ofthe main conveyer and the, receiving beet hopper, `relatively tothe. railroad 'trackage, it I beingppartieularly noted that said hopper extends in longitudinalline with;` a11d has itsdischarge outlet disposed in the plane, of s said' main conveyer, andwhich driveway will V.preferably lie in a` level andfapproxi- `mately straight V:path from the said hopper ytofthe tare receptacle. i

f VFurther primary objects ofthe invention reside in the improved structural features of the'apparatus itself and the novelcombina-- tion and' arrangement of the elements thereof,including the novel form and disposition of the beet hopper withV an initialy feeder conveyer associated therewith, vfor delivering the beets withga moreregulable and freely l l,

discharging feed from the hopper to the inclined endless conveyer; they structural form of the gallows hoisting framework,

associated'withsaid hopper for dumping the l heavily loaded field-wagons, which framefwork is of portable character or which may be readily knocked down for portability;

yand also including the novel arrangement of cross-conveyer units associated in combination with the discharge end of said main inclined conveyer.

The, foregoing and other features, objectsand advantages of thegimprovements, however, will be so clearly apparent it is believed, as incidental to the followingdis-` closure, kthat no useful purpose would be servedY by further enlarging upon the same initially, and with thesegeneral `outlining remarks', therefore, reference will now be immediatelyV hadto the accompanying drawof Figures V1 and'2; Figure 2 isa plan view iso of the apparatusas associated with the rail'- road trackage, and showing f the clearance space for the team driveway from the receiving hopper to the refuse or ytare receptacle;-

Figure 8 is lan end elevational view of the 'discharge end of the apparatus, p and also showing in dotted lines a 'railroad transportation beet car, positioned for the reception ofthescreened beets, as well as one ofthe A field wagons or trucks in position', under the tare receptacle, for receivingv the, refuse material from itspreviously dumped load of beets; Figure 4 is an enlargedfragmentary view, analogous to Figure "3, partlyyin elevation and partly in longitudinal yvertical i section through thev screening cross-conveyer and-thetare receptacle; and Figure 5 is an end elevational view at the receiving hopper end of the apparatus, being'a vertical transverse'seetion `along the line 6,-?) of Figure 2,

A and also showing in4 dottedoutline one ofthe fl 5o field wagons or trucks as located at its dumping position. i l Y It mayfbewell to initially state, for a 4clearer conceptionof the generallayout of the' apparatus, that in 'carrying out my invention I preferably provide al main inclined `conveyer structure 6,adapted to be disposed infa plane substantially parallel to the rail- Y road trackagel, Lwhich main Vconveyer at its upper end is associated witha laterally disposed or cross-conveyer that is in turn associated with a terminal cross-conveyer 8, in the form of a screening unit, adapted to discharge at'substantia'lly right angles over a transportation car'14 on the railroadV track,

i a substantiallyelevated" tare receptacle 9 being located directly underneath the inner end of said screening conveyer; while at the -nearside of the apparatus relatively to the railroad trackage, and it being particularly noted that the said main-inclined conveyer, the said beet load receiving hopper with its discharge outlet, and the interposed said initial feeder conveyer are :all disposed in endwse alignment wtheach other, or extend `in the same longitudinal plane which in the,

layout as illustrated, and preferred, is a verticalplane parallel to the railroads-trackage. Accordingly, the whole arrangement provides for a wholly unobstructed clearaiicej space 15, along the railroad right of way between the trackage and the apparatus, whereby the field wagons `or trucks 12 are hauled over a substantially straight driveway 16, as indicated bythe llong arrow ofY Figure 2, from the beet hopper 11 to a position under the tare receptacle 9.

All of the conveyersare of type and, in so far as my present yimprovements areconcerned, may be of any suitable form in detail, but I prefer that the conveyers 6, 7 and 10 be of roller supported endless belt structure, as distinguished from an endless seiies of pan, bucket or Alike conveyors im? which tend to Ybruisethe beets. Also, as a matter of preferred structure and in order to avoid a moie prolix description, although it may be necessary in some instances later on to go more into detail, I have illustrated the ma main Vconveyer 6 and the terminal screening conveyer 8 `substantially of the same forms,

Y although disposed differently in assembly, as shown in UnitedStates Patent No. 1,432,195 grant-ed October 17, 1922 to James A. Lynch, i if* and the intermediate cross-conveyer may be of substantially the same structure asY the main conveyer, while the feeder conveyer 1'() the yendless i i is illustrated as being substantially the same as that disclosed in my prior application, for N5 endless belt'conveyers, filed October 6, 1925 underl Serial No. 60,828. *Y

fr suitable equipped"upstanding framework or tower 17, preferably builtof structural steel, supports the beltcrossconveyer l2@ 7 which may be conveniently termed an auxiliary or interposed .cross-conveyer, the terminal. screening cross-conveyer 8, the tare receptacle 9 `which has an open bottom closed by a counterbalancingly weighted or self- 125 closing and latcliing door 19, and the upper Yend of the main' inclincdconif'eyer 6; but

the lower end of the main conveyer 6 preferably extends iny proximity to the ground level, and may be ,projected into a concrete 13 1', ser, rar

As the samey 1s so lgearing connections are only showninore or lesseoxrventiona-ll lise, as `in the Lynch patent aforesaid, it will be noted that an apron' or bottom wall 3S)l extends, underneath the lower por! Vtionj of theendless series of 'slats 40, from thej forwardV end' of the screening' conveyer 8 towardsthe rea-r thereof, for deli-vering the screened outl refuse from the beets to thev tare receptacle 9: Likewise, it will beV further noted that vthe screening conveyer` framev is liing'edly mounted, withilts' tail end over l y 'and described generally. for'the sake of: brevity.

Outside of the noyellbroad arra'ngement'vof the cress-conveyers relatively to .the mai-n conveyor (l, Vl-iowever, noaparticularelaim is made te` thel specific Vconstructions thereof, sevtliat further detail'ed'description of-tle same is not' believed t'o'- beL necessary' nor desirable. Y i

In vnow describing features,- p'erliafps, of my improvements in the more' importantk combined arraiagement;` with the lower end of the vmain conveyefr 6, as has before .been stated? the feeder I* con-Voyer r 10 is preferably mounted on` the bottomofapit 20, sunk below the driveway 116', with the inclined lieadhsecti'onf 22 ofsa-id feeder conveyer dis# `charging longitudinally over auchuponftlie lower end of the-main` inclined7 conveyerj 6?, whi'cli latter in turn is adapted tobedis'- poscdf in 'av vert-ical plane paralleltothe railroad trackafge. I f Y, I Y l .immediately above thehorizontalE tail section=--2l"ofltlie feederconveyor lfO, and( with its lower portion disposedv within sai-d pit,

is mounted the beet load receivinghop'p'er 11,

built up of steel ben-ts preferably andwall boards, which hopper is of anovel'fconstru'ctiom'peculiarly adapted? for the beet dump s tion, and extends Vfis-beforev statedff-in-` longitl linal line with both said feeder and mai-n conveyers.

nearside wallj 4:2 ofth-is hopper, relatively lt is teil3@ particularly noted that the los lll)

tothedriyeway 916, is ofgsubstantially less,y

heightlr than the rfarsidel wall el?) thereof, thel two downwardly convergent said side lwalls so-'terminating at theirflower edge portions as to provide. for a. longitudinally extending 'slot or bottom discharge opening, which preferably diverges forwardly, as indicated by therearwardly tapering lower'end portionsA lle. The rear of said hopper may be closed by a Aboarded wallet), andi the forward end` parti-ally closed by the boarded wall 46, excepting at theI cent-ral Zone-thereof rae wherel it is left unobstructedfas at 47, to provide a forward discharge opening for the hopper, in line with the bottom opening thereof, which forward opening is in open Y unobstructed communication with a forward discharge throat that simply Ycomprises a pair of upstanding sideV or flanking walls w48," preferably convergent slightly both downwardly and forwardlypas seen more clearlyfromFigures 1 and2. Y

. It being understood that the bottom opening 44 of the hopper andthe bottom opening between theA side walls 48, ofthe forward discharge Vguiding throat therefor, are disposed immediately overthe horizontal and )inclined .poi-tions, respectively,of the conveyer belt of the feeder 10, .will be apparent that the side wallsof the feederconveyer may bemade quite shallow, and at with this particularI type yand disposition of Y fof the iieldwagons into the hopper, becausel the, beetV load receiving hopper, it isA not necessary to build up an elevated platform oirwagoii-way at. the station to-provide for Vthe dumping ofthe heavily loaded contents thelower or nearside wall 42 of the hopper --is :disposed adjacently of and projects only a short Vdistance above the team driveway level 16, as seen most clearly from Figures 2f and 5, which arrangement provides for asubstantially level and ystraight driveway ffor the teams, along the actual railroad right-of-way betweenV tlietrackage and the apparatus,V as thus located, from the beet hopper tothe tare receptacle, whereby there is afforded suoli a clearance space or driveway that is wholly unobstructed by the apparatus `asj a whole, or any part thereof, either with referenceto beet hauling field wagons orany other type of ,veliiclesordi- Vnarily, using the roadway,`a`nd without the necessity of having to haul theheavilyloadedA field` wagons initially up an incline" or i ramp, `for dumpingftheir load of beets into the hopper as is now customarily done, which rfeature of itself is very important from a 1 trucking viewpoint.

lill

i A' wagon tilting gallows or y hoisting framework surmounts the pit 20, in straddling or encompassing relation with therbeet hopper, and may embody thev open base frame structure 49 having an upstanding postbeam 5.0 from which is'proJected the hoisting kbeam 51, Vextending laterally, over,V

the driveway 16 in the Zone of the; hopper, this upper structure kbeing suitablyk braced and trussed by the angularly disposed strut bars 52 and53. The outer end of the hoisting beam 51 suspends a tackle block arrange-, ment 54, associated with the aforementioned hoisting cable 28 that reevesrespectively over and under theV upper and lower guiding pulley Vwheels 55 and carried by the base frame structure.

This hoisting framework and also the tower framework 17 are'preferably formed of structural steel which may be facilely assembled and also readily knocked down` for removal and reinstallation purposes, and as the hopper, the feeder conveyerthe main conveyer, the auxiliary conveyer, andj the screening conveyer, together with thelatters tare receptacle, arebuiltup as independent portablerunits, it yis obvious that the. whole station may readilyv bedisassembled and transported units, for reinstal-V lation at'another place or for storage during" closedseasons, in avoidance. of `deterioration. Or as a matter ofvfact, which will also be obvious, the apparatus as a whole,'or as attachable and detachable units, might readily beY supported Vupon a wheeledfbase structure or separate structures, forV selfportability as it were.

asV

Although not actually shown in tliedrawings, it is to be understood that the belts of the main conveyer 6 and of'the feeder conveyer 10 are provided on their outer or conveying faces with laterally disposed cleat-like spaced abutinents, preferably spring steel bars or slats mounted asdisclose-d in my aforesaid applicatiom'to'properly convey the beets'and refuse up the -inclin-es, as well as to support the belts yagainst undue sagging.

Finally it may be emphasized again that, y

with thepreferred arrangement which in its broader sense also involves a vnovel method vof handling the beets at a beet dumping station, the heavily loadediield lwagonsiare tilted, bythe hoisting vblock and tackle means 54, to dump their loads into the receiving vhopper from the ground level andiover the shorter nearsideof the hopper, relativelyto thevrailroadtraclage, without the necessity leo of being hauled up an inclined platform structure, the building of which latter would also involve considerable expense, andfrom that dumping position ther emptied wagons are then hauled over a substantially level'rand lstraight driveway, along the railroadrightof-'way between the trackage andthe apparatus, to a position underneath the "tare receptacle 9, for receiving the screened out dirt from the initially weighed load. ln the meantime, the beets and refuse ofv any lparticular load are gradually fed. torand along the feederconveyer 10, as .hereinbefore deizo igeearsi scribed, discharging to v"the lower end of the maininc'line'd conveyer-6, disposed in a verandfrom thisfauiriliary cross-conveyer 7 theV tical plane parallel to the trackage, 'from the upper-end of which .main conveyer lthey vare again 'discharged tolthe inneriendv of vthe cross-conveyer 7 which 'is disposed vsubstantially at right angles to the main conveyer,

' ceptacle 9.

During this travel of the beets, along the several endless conveyer units, they have three distinct but slight tumbling over or cascading motions, once on discharging from j the feeder to the main conveyer, again on discharging from the main to the auxiliary cross-conveyer, and nally upon discharging from the auxiliary tothe screening conveyer.-

Each of these short falls imparts shocks tending to substantially dislodge the clinging dirt from vthe beets, without bruising the latter, so that in passing over the terminal screening conveyer the refuse is more completely sifted between the endless spaced series of bars thereof, being further aided by the wave-like agitation thereof caused by the intermittently 'impacting arms 35 of the rotating spider.

From all of the foregoing, it is believed that the full objects and advantages of the invention will be clearly apparent, but although I have thus set .forth the invention in detail, in accordance with my present preferences, it will neverthelessbe understood that I do not wish to unnecessarily confine myself to all of the details exactlyas disf closed, excepting as they may come within the terms or'l tenor of the claims, or equivalent steps, elements, combinations and arrangement thereof, or as fairly interpreted in the light of the specification if necessary. f

in a vertical plane substantially parallel lVhat l do claim, as new and patentable, is
