'T0` all whom it4 may concern: Be it knowny that I, JOH lilVHi'rE, citizen of the United States, residing at Bloomington, in the countycf McLean end 'State of Illinois, havelin rented certain new anduseful Improvements in Wa on-Dumps,' of which the following isa speci cation, reference being had therein to the accompanying drawing'.`

lo This invention relates to an improvement in unloading apparatus, more 'particularly to that class or type of apparatus Awhich is designed for'use in connection with a wagon or other vehicle in which material'is to be i5 transported, and whichwagon or vehicle is'y y required to be dumped for unloading purposes. vAt the present time many'so' 'called wagon dumps-have been suggested and associated with such 'dumps usually endless 20.carricrs or elevators have been "employed onto whichV thematerial is dumped and by which the material is transported to the bin, granary, or other depository.l

In the prior art it has'been usual .to'provide a so called wagon dump with means for raising the forward part ofthe wagon so as to dischargetlie loadxtherein from the tail end of the wagonland ,suitable drags, so. called,

. have beenem-ployed for receiving' the ma- Soterial trom the wagon. These drags have .been provided with endless conveyers andV the material has been conveyed thereby into an elevating carrier. These elevating carriers have in some instances been arranged 35 parallel with the dump and in some instances have been arranged at right angles to the dump according to the positionof thecrib or granary. -Ithas been usual to raise and lower the elevators so as tol accommodate l40 them to granariesV and bins of` different heights. The driving power for lthe elevator, drag, andthe dumping device has usually :been in .the form of horse -power so coupled with the various members that they are all driven or actuated by a single horse power vor motor. f

M invention relates to improvements in -this latter class of machines and the objects of the invention may be stated brieiiy as follows: first, to so cor-.struct an unloading device that the elevator or conveyor may bev `adjusted to extend in direction either transvers'e'for parallel with the platform of the niamchine; second, to provide suitable .means tir-wliereby the transfer drag can be operated Specification of Letters Patent.

with equal ,eiiiciency irrespective of the adjustment or-position yof the elevator proper; third, to provide suitable mechanismv for vactuating .the dump with automatic actuating means for governing the movement of said mechanism; fourth, to provide a .dump with means for raising and lowering the saine, and means for` automatically governing the raising and lowering ofthe dump whichautomatic'nieansare actuated independent lof the l65a dump; iii th, to rovide improved mechanism for governing t e upward movement of the dump, releasing the same, andpermitting its adjustinent for lowering movement; sixth, a dumping device with means for automatically governing the 'same and associated with said automatic means, suitable mechanism for variably actuating the dump in its .up and 'down movement respectively;. and iinally to provide an unloading device which will possess the necessary characteristics rendering the same largely automatic disrhn'sing with manual labor and the requireni ntof specific attentionfor regulation and movement of the various parts.l v

the drawings accompanying these specicat ns I have shown an embodiment of the appar tus containing theinvention presently to be described', but it is to be'undjerstood that the illustrated machine is susce tible of wide changes and modifications, an in fact the parts maybe entirely changed, some vmodiied,and some omitted, without depart-v ing from the principle of the invention, the illustrated structure being employed in this speciiication more for the purpose of illustrating the principle of the invention lthan the exact details, and therefore I do not wish to be limited in my protection to the speciiicV construction shown. 95

-Figure 1 is a sideelevation of 'a machine embodying the invention;'Fig. -2'is a plan view partly in section; Fig. 3 is aperspective view. of a portionof the machine; Fig. 4 is a detail'view of thelower porti'on'o the elevator; Fig. 5 isa sectional view of the gearing for the dump showing parts in elevation. Fig. 6 is a section through the standards; Fig. l7 is a detail view of a porti-on of theelevator and drag; Fig. S is a planl view of thef trarne.

In the drawings the platform A is supported on suitable frame work, 'and' has at its opposite ends drive-ways. At one side of theA platform, at the rear, is a supporting frameshaft A Work B carrying thereon a removable boxing B into which the lower end of the elevator or conveyer C extends, the same being conveniently mounted on its flight driving shaft one side of the boxing being cut away for that purpose. At right angles to the elevator is the drag D of any improved type having an endless conveyer therein. The end of this drag is let into the side of the boxing B and is held directly above the lower boot or end of the elevator, the drag standing at right angles to` the elevator. Suitable gearing, as for instancea sprocket chain b extends from the driving shaft A over suitable sprockets, one being on the shaft and the other being on the driving shaft of the drag. To actuate the endless flight of the elevator, conveniently I extend a transverse shaft A2 below the platform, mount the saine in suitable bearings, and couple the same with the shaft A by suitable bevel gears a, azfand on the shaft A2 is mounted a sprocket wheel a over which a chain passes over the sprocket wheel a4 on the driving shaft of the elevator.

In this connection l have also found it advantageous to providethe ends of the shafts A and A2 with squared ends with which the power driven shaft from a suitable horse power or motor can be coupled. ,As shown in thev drawings it'will be seen that the shaft i lextends the 'length of the machine and that both ends are provided with squared extensions so that I am enabled to couple the horsepower up with the machine at three different points, namely, to either end of the or to the end of the shaft A2. This is convenient as it permits the use of a machine in places where it would be inconvenient to utili-Ze the horse power were it permitted application to one point only,

ln constructing the parts of thc elevator and drag as above described, .l have found it. necessary to cut out a triangular section b from the side of the elevator boot or base so that the end of the drag will project su'llicientlv over the edge of the base of the elcvator. rThis small lcut out section fr* is adapted to be replaced and held in place by suitable straps such as fl, for purposes presently to bc stated. It will also be noticed by the above construction that the velevator stands parallel with the machine or platform while the drag stands at right. angles thereto, the power driven shaft being arranged to ac-` tua'ie th'e lliglits of both the elevator and drag. Should, however, the conditions demand that the elevator' be adjusted to n. point at, right angles to the platform, thi` construction which-l have above described will permit of such readjustment, with this varia- I;

tion; 'l`he boxing l may be conveniently re moved and a V-shaped portion fr* replaced to complete the continuity of thi` sides of the elevator, the elevator is then turned at right angles and bolted or secured by other suitable means in place to the frame B suitable sad-- dles B2 conveniently being employed. The driving shaft carrying the sprocket wheel for driving the flights of the elevator will stand parallel with theplatforinwhile the driving shaft of the drag is in the-position it formerly occupied. To transmit the p'ower of the shaft A to thc'driving shaft of the elevator I place on the former a supplemental sprocketl Wheel a5 over which the driving chain passes, after passing over the sprocket on the elevator, as shown in Fig. 7. The elevator is then supported in the usual way by aderi'ick or other means, and the parts are operated through the driving shaft. I

At the front ends of thev machine, site sides are the standards E, F, being somewhat larger in proportion than the latter and between these standards is the elevating frame G conveniently composed of parallel side bars and connecting end bars in a well known manner. To elevate and lower the elevating frame suitable cables c, j, are attached to bails connected with the ends of at oppothe frame, and pass up over suitable pulleysez, e3 mounted on the top cross-bars of the uprights. These chains are carried down between the vertical bars of the uprightsor standards and have their lower ends connected with suitable drums l, F mounted on the cross-shaft F2. By turningthe drums the chains are wound thereon and the elevating frame is moved up and down as the case maybe. To guide the elevating frame in its movement suitable rolls or wheels q are employed working against the outer faces of the side posts of the standards, as shown, which are carried by the elevating frame. 'lo actuatet-he drinn slnift l`"'. at one end it is equipped with a suitable worin wheel F which meshes with a worm li, the parts being mounted in suitable bearings in the casting ll, suitably bolted to the frame work and standards. 'llie castingy ll formed of three or more branches. the upper ends of each constituting bearings for a parallel loose shaft J, the extreme rear end of which is mounted iii a fixed bearing i on the platform. 'lhe shaft l has lixedlv secured thereto a clutch collar lf which .in turn loosely engaged by a forked lever li pivoied at K2 on the cross-bar i' on thi` standard l.

yThe rocking of this lever li moves the shaft J longitudinally and brings the clutching ends of the collar li into clutching engage ment with complementarv fares of the bevel pinioiis li, li which are loosely mounted on the shaft d. 'lhese pinions l,. li are in un-` i with a bevel pinion lf mounted on the ouii-r end of the worm gear l", so that as the pinioiis l. oi li are i'olipled lo the shaft -l bi.'

f the clutching faces thereof and the clutchingf collar on the shaft, the movement of the shaft J will be transmitted to 'the wheels driving the worm gear in the direction ol' the wheel the former lllj which is being actuated. To drive the shaft J, I have provided suitable sprocket wheels:

J3, J4 the former being of greater diameter than the latter. These wheels are loosely mounted on 'theshaft J and are held in their keyed to the shaft, is movable with the shaft Vthe shaft J.

longitudinally so that as the shaft is moved it will bring'the clutch member'Klas'well vas the clutch'member J into engagemen'trwith on'eof tlie s'jprocketv wheels J, J", and one of the bevel gears L, L.' Thesprocket wheels are each provided with"clutching faces-to correspond with the clutching member J'f Onthe shaftl A"are placed sprocket wheels M and N the former being relatively smaller than the` latter and being in-'li'ne with the sprocket vwheel Ji* on vthe shaft J lwhile the i sprocket wheel'N being the larger of the two on the -sha'ft A is associated'with or inline with-that of th'elsmaller sprocket wheel J4 on Suitable drive chains pass over the-various sprocket wheels asshown.' y

By the above' arrangement it will be seen that 'when the -dumping'frame is. to be ele' vateditis only necessary-to adjust 'the lever K to'couple 'the larger sprocket' wheel J3 with the shaft J 5 thereby'reducing the movement ofthe shaft J owingito 'theidifferential sizes of-the gearing or sprockets. The worm' gear is thereby slowlynoved which action slowly or gradually winds up the elevating chains/and the dumping'frame'. This slow movement is necessary' and desirable so that' the contents of the'wagon will be discharged-v and simultaneously carried off by the 'drag and the elevator, the discharge from the wagon being'equal to-tliecapac1`ty ofthe elevator, `When-the dumping'irame is-to' be loweredthe shaftJ is shifted in anop osi'te direction and owing to the diiierentiai) of the gearing which are by that movement coupled, .frame is lowered very rapidly' but regularly, thussaving considerable time in replacing the wagonafter the load has been emptied. ,i v

The clutchandadjusting arrangement of the above construction may be advantageously adjusted by hand if found desirable, but I have found it advantageous to acquire such movement through the automatic arf-- tion of the machine, and to this 'end have provided the following mechanism: Mounted on suitable cross-bars in thewupright or standard }},sligl1tly above the end loi the lef ver K is a wheel P, the same being carried by a shaft I mounted irl-bearings iu thecross bars and having its outer end bent down into the form ofi a crank, the outer ond of which engages through an elongated slot p m the4 end of the lever K. The opposite end ofthe shaft P is bent upward an( thence inward to a point directly above the periphery of the sizes I wheel P. Passing over the wheel P is a,A Vsprocket chain or other convenient form of driving belt Q, its lower end passing over a sprocket wheel ZR mountedon the shaft and receiving its movement therefrom; 'The 7 0 chain Q is provided with trip projections or linksvr, extendirur out laterally therefrom l (I. e

.and designed to engage ythe inturned end` p `of the end ofthe shaft P as the Acham 1s moved These'trip projectionsor links are 75 so positioned on the. chamQ that as the Adumping frame is elevated and reaches the linut of its upward movement the projection g will come inlcontact withvthel projecting end p of' the shaft P forcing Iit rearward, rocking A80 thev crankarmon the opposite end of the shaft and thereby rocking the lever K', shifting' the clutching mechanism Yso that by moving the crank by hand a further distancel it will limmediately throw into action the` mechanism for lowering the 'dumping frame. The Jframe will 'thenimmediately descend vwith relatively great rapidity until the projection qcomes in'contact with the end p of the shaft' Pv changing the` position of the crank on the latter and stopping the descent and -setting the machine forjad'justment to Operate in va reverse direction. By this conl struction the machine for elevating the front end of the wagon is made Vautomatic in its lstoliping action independent of the frame,

its travel vvupward beingv limited, andl the move-ment being reversed-through the lever K whileitstravel downward is also limited and reversed by the lever and its clutch. A The lever 'K is' automatically moved initially and the shifting movement is completed by the operator. It will be understood that. while this part of the inventionas shown in the form described, is satisfactory, the same result can 'probably be accomplished by widely'dierent mechanism. It is this independent governing of the dumping fram-o which I belie've to be broadly new in this art.

When' the elevator is in the position shown 110 in F' ig. 1, it is necessary to have 'some provision for raising and lowering the same tov change its angularity. This l havey arf-,omplished by providing the standard E witha guide-ways in which works a verticali)Y reciprocating bar S.- Thisbar S carries on its upper end a shaft s provided with suitable wheels's on which the lower edge of the 1levator C rests. Bymoving the bar S up and down, the elevator trough is also moved up and down, and Ato accomplisli' this movement -I mount in the standard E-a drum 'l` to which jdrunrT is a' crank, and a suitablel ratchet,-

wheel Tv'with'wliich'a pawl'll engages. The bar S 1s guided m its up and down movement by having a suitable track S' resting 130 j against the flanges ofthe idler wheel tilso that as the bar is raised or lowered, owing to beemployed extending to the rear of the mac chine in convenient reach of the operator, and also that a sultable chute such as shown at lV may be' employed at the upper 'end of' the elevator, when desired.

I am aware that dump actuating mechanisms have heretofore been governed in their elevating movement by a trip which is struck by the elevating frame, thereby limiting the u movementof the dump, but as far as I am a vised I am the to actuate a trip, stopping and reversing means by mechanism actuated independently of the elevating frame or dump.'
