This invention relates to dumpwagons, the broad object of said invention beingto provide a wagon of the class described, which is capable of various operations in order to expedite and facilitate the discharge ofthe load therefrom in a manner most convenient to the. operator as well as minimizing trafficobstruction,

One object is to provide a dump wagon. having a bottom discharge and capable .of, being automatically emptied or unloaded, partially or wholly from either side of thewagon body.

Another object in View, is to-provi'de' for emptying the load partially or Wholly fromthe bottom.

Another object in View, is-to provide forxdirecting the discharging load toward either side, bottom, front and rear or practicallyinalmost any. direction downwardly or inclined from the bottom discharge opening of the load body.

Another object in view, is to provide means for the carriage of. separate. units or different materials and permitting separate ,or combined discharge of said load units.

Another object in view, is. to provide-means for leveling, stabilizingv ordistributing the load body contents after part of, the load has been discharged and the remainder is carried to a different destination. w o

Another object in view, is to provide means, for the sectional removal or assembly of the load body division boards as may, be required.

With the above andother objectsin view, the invention consists substantially inthe combination, construction, location and, relative arrangement of parts, all as will appear more fully hereinafter, as shown in the accompanying drawings-and as finally pointed out in the appended claims.

In the accompanying drawings: v

Figure 1 is a side elevational view of a dump wagon constructed in accordanceswith and embodying the principles of the present invention; Figure 2 is a plan view of the dumpwagon embodying the present invention, the fore and aft standardsv being shown in horizontal sec.-

tion; 4 I

Figure 3 is a side elevational view of the displaceable, longitudinal, center or division board and gate operating means; r

Figure 4 is a top cross-sectional viewof-the central, grooved or channeled binding; post for engaging the central ,endsof' the-four division wall sections; and .1. r I Figurefiis a topplan viewrof the dumpfb ody, division walls and. division wallgate operating means.... 7. Referringlnowrmore particularly to the draw ings ,it.wil'l be observed that the wagon body orreceptacle tor the. load as shown:is of invertedsfiusto-pyramidal;shape. While this is the preferable shape, it will be understood that the invention. or inventions. to be described more. fully hereinafter are equally applicable tobo'di'es or load receptacles ofi different shapes than that shown in the drawings, thexprincipal characteristic of the": body with.which this invention: isconcernedbeing that the side walls thereof. converge downwardly toward an .opening in. the bottom ofthe body. In the drawings the load. receiving body is-designated generally by thereferencentuneral. 10, the centrally disa posed. bottom opening .or outlet having suitably secured 'toythe perimetral edge thereof a frame member. provided with;v intersecting division strips H. and. I2 whereby to provide aplurality of substantially equal-sized openings .13, each of which constitutes anYindividual discharge outlet. It will be apparentnthat by the provisionof. the four discharge outlets, the material .contained in the body imay be discharged throughany one. or more of the said discharge outlets. i V 7 As: is described in my copending application above identified, each of the discharge outlets 13 thus provided in. the bottom of the body is adapted to be opened and closed by a horizontally arrangedrslidable closure member, these 'closure'members beingal-l movable in directions extending longitudinally of the. main body I. The arrangement of these closure members and the means for efiecting'their operation will not be described herein. Should a more detailed description thereof be desired, reference is made therefor to my copending application Serial No.

tangular formation, thus permitting not only a vertical movement of the discharge chute 20.

therewithin but also a circular movement thereof when the body H1 is in lowered position, the

openings I1 in the side walls of the vehicle frame being of suflicient lengthand depth as to permit the free movement therethrough of the outer end of the discharge chute.

Suitably secured to the upper end of the circular body of the discharge chute isan annular'rack bar orworm gear:2| which is adapted for meshing engagement with and actuation by aworm 22 fixedto a transverse shaft 23 the opposite ends of which are journalled,ias at 240., (see Figure 2) toathefoundation board or platform' [4. This shaft 23 is arranged to be driven, through a. system of meshed bevel gears, by a vertically extending, rotatable shaft 24; This shaft 24 is suitablyencased within a supporting tube or casing .25 which isv securely held inrposition at its upper end by'a bracket 25 (see Figure 2)..cmount'ed upon the side of the main body l0. r

Secured to the lower end of the'shaft 24 is an operating handle (not shown herein) for effecting the desiredarotation of the revoluble discharge chute 20, from the ground regardless of the vertically adjusted positionof the main body, the arrangement being such that regardless whether the said body is. raised or lowered, the transverse shaft is constantly in operative association with" the vertical operating shaft 24. Preferably, the lower end of the rotatable shaft 24 is journalled. within a bracket (not shown herein) mounted upon the side edge of the vehicle frame I6.

Mounted upon the upper framemember I6 of the vehicle truckat the fore. and aft/ends thereof are a pair of uprights or standards 21 and 28.' Inasmuch as these standards and their associatedparts are described in detail in my copending application aforesaid and in view also of the fact that these standards are not vitally essential to the operation of the invention with which this application is concerned, their construction will not be described herein,xit.being sufiicient for the present. purposes merely to point out that these standards 21 and 28 embody elevating means for raising andlowering the main body ID as may be desired.

Preferably, the upper ends of the fore and aft standards 21 and 28 are preferably respectively covered by the caps 29 retained in position by means of the screw bolts 30. These standards 21 and 28'are respectively slotted, as at 3!, in the faces thereof which present toward each other in order' to permit the free vertical movement of the substantially T-shaped extensions 32 provided at either end of the foundation-board or; platform l4, these extensions being retained within the standards 21 and 28 and guided during the vertical movement ofthe platform by" the vertically extending ribs 33 which define the vertically extending'slots' 3| there may be provided thepull cords, 39, 40, 4|

and 42; or the hand-operated levers 43, 44, 45 and 46.

a .As appears most clearly in Figure 1, the main body 10 is provided with a plurality of side loading doors 41, these doors being respectively adapted for movement in vertical planes, the doors being closed when they are moved into their uppermost position as shown in Figure 1. Preferably, a pair of such doors are arranged to either side of the main body in longitudinally spaced relation.

The mechanism for operating these side load- I ing doors 41 will be but briefly referred to herein, it being deemed sufficient for the purpose of this divisional application to point out that the side loading doors are arranged for simultaneous operation by means of vertically arranged elevating screws 48, all of the latter being commonly' actuated bya shaft 49 to which desired rotation is imparted by a forwardly located hand operated wheel 50.

It is preferable to provide some means for.

subdividing the main body l0 into a plurality of individual compartments and to this end there is provided a pair of vertical sections 5| and 52 and a second pair of vertical sections 53 and 54, these vertical sections being so formed along their inner vertical edges as to permit their slidable retention within suitably formed vertically extending slots, grooves or channels 55 provided in a central vertical post 56 (see more particularly Figure 4), this central vertical post 56 serving to detachably secure the division wall sections 5| to 54 together. Suitable bifurcated lugs 51 orthe like are secured to the inner faces of the side walls of the main body I!) for respectively receiving the outer edges of the division wall sections 5| to 54, these lugs 51 being preferably provided with set screws 58 or the like for rigidly securing and retaining the division wall sections in position. As appears quite clearly in Figure 2, the division wall sections when properly'positioned within the main body In constitute irf effect a longitudinally extending partition which is intersected substantially at right angles by a transversely extendingpartition, the longitudinally extending partition being disposed substantially in the plane of the division strip l2 of the bottom frame and the transversely extending partition" being disposed substantially in the plane of the transversely extending division strip ll of the bottom frame. There is thus provided four compartments which are respectively provided with the discharge openings l3 (see Figure 2), each of which openings is provided with its own individually oper ated trap door, as already described. The four compartments so provided are thus adapted to be filled with different materials for individual or selective discharge through their respective discharge openings or the four compartments maybe filled with material adapted to be .discharged in one operation by simultaneously open-ing all of the trapdoors. upper edges of the division strips H and l'iv of the-frame surrounding the bottom openingin the main body H) are grooved-or slotted longitudinally thereof to snugly accommodate the bottom edges of the division wall sections 5| to '54.

As appears most clearly in Figure 3, each of the division wall sections5| to 54 is provided in the bottom thereof with a vertically movable gate 59. Each of thesegates 59 .has fixed adjacent the upper. edge thereof an interiorly threaded socket 60 or the like through which is vertically projected a vertically extending screw 6|, this screw being suitably journalled in a bearing 62 secured. to the upper portion of the division wall section. Fixed to .the upper end of each screw BI is a pinion or gear wheel 63, the pinions 63 so carriedby the vertical screws of the transverse division. wall sections 52 and 54 respectively engaging suitable Worm gears or the like 64 carried by short shafts 65 and 66.- These shafts 65 and 66-extend in opposite directions from the central axis of the main body l0 and are journalled for rotation in suitable bearings 61 mounted upon the upper edges of the transverse division wall sections 52 and 54. As appears most clearly in Figure 5,. the proximate ends of the shafts 65-66 are respectively provided with pinions or gear wheels 68 and 69.

Extending longitudinally of the main body Ill and lying substantially in the plane of the division wall sections 5| and 53 is a shaft 10, this shaft being provided with a screw or worm gear 1| for meshing engagement with the pinion 63 of the screw 6| carried by the forward division wall section 5|. The forward portion of the longitudinally extending shaft 10 is supported within a split bearing mounted upon the upper edge of the forward division wall 5|, bearing being hinged to the other portion thereof whereby the bearing may be opened to permit the removal of the shaft. The split bearing. is preferably maintained closed by means of a thumb screw 12 or the like. The longitudinally extending shaft 10 is projected through a second tubular shaft the forward end of which is provided with a bevel gear or pinion I3 adapted for meshing engagement with the bevel gear or pinion 69 carried by the short transversely extending shaft 66. This second tubular shaft is in turn projected through a third tubular shaft 14, the forward end of which is also provided with a bevel gear or pinion 15 adapted for meshing engagement with the bevel gear or pinion 68 carried by the other transversely extending shaft 65. The last-mentioned tubular shaft 14 is projected through still another tubular shaft 16, the latter being provided at a somewhat removed distance from its forward end with a worm or other such gear 11 which is adapted for meshing engagement with the bevel gear or pinion 63 fixed to the upper end of that vertically extending screw 6| which is carried by the rearward division wall section 53.

It will thus be observed that the central shaft I0 and the three tubular shafts embracing the same are all coaxially arranged with respect to each other, the outermost shaft being of shortest length and the innermost central shaft being of greatest length. This coaxial shaft assembly is suitably supported or journalled within bearings 18-18 in longitudinally spaced relation upon Preferably, the

one portion of this the upper edge of the rearward division wall section 53. Preferably, the central shaft 10 and the tubular shafts surrounding the same are separated from each other by suitable ball or roller bearings (not shown). 1

Respectively secured to the rear ends of these four coaxially arranged shafts are the hand wheels 19, 80, 8| and 8'2, it being apparent that upon rotation of thehand wheel 19, the gate in the rearward division wall section 53 may be lifted vertically. Similarly, by operating the hand wheel 8| the gate in the division wall section 54 may be vertically raised or lowered, while operation of the hand wheels 80 and 82 respectively effect vertical movement of the gates in the division wall sections 52 and 5|.

Preferably, the division wall sections each are provided with hand holes 83 (see Figure 3) to permit the removal of these sections by means of an overhead crane or tackle. By means of the selectively movable gates 59 in the several division wall sections 5| to 54, the operator of the vehicle may readily stabilize the load contained in the main body l0 after a part of this load has been delivered or he may speed up the discharge of the load, as when only one of the four compartments is filled with a slow-moving material and it is desired to make available all four of the bottom discharge outlets I3, it being obvious in such case that when'all of the gates are raised the discharge of the material from the single-filled compartment will be greatlyaccelerated.

These division wall sections which sub-divide the main body into a plurality of separate and independent compartments allow for'single or multiple delivery at the same time that they provide a very effective means for stabilization of a part load in order to affordsafer transit over rough roads. The vertically movable gates in these division wall sections facilitate not only this stabilization of the load but also may be employed for accelerating the discharge of a slowly moving material.

It will be understood, of course, that the invention is susceptible of various changes and modifications which may be made from time to time without departing from the real spirit or general principles thereof and it is accordingly intended to claim the same broadly, as well as specifically, as indicated in the appended claims.
