Fig. 7 is a view similar to Fig. 5 showing the parts in the positions which they occupy While the train or group of cars is on a curve.

Fig. 8 is afragmentary, vertical sectional elevation of the i'ront end of the driving unit of the train.

The conveying system includes a group of vcars or train which is rmovable from aplace where the material is received to a relatively stationary train dump machine A, to which the train or groupoi oars discharges the material, and which in vturn discharges the material into the desired location. The tra-incr group lo'cars vmay consist 'of a plurality of iiat, hopper bottom cars B, and a motor car C, which lis also adapted to carry a certain amount of material. A number of these trains may be employed, and the trains may operate on a tracll: D, which may be provided with a number et sidings D. E represents diagramniatically a steam shovel 'or `other dcvice for loading the material on the cars. 'It will be understood that if the system is used .for laying railroad road beds or the like, the track D maybe extended as the road bed is laid, so that the dump car or machine A may be advanced from time to time as the road bed is completed, and the additional track is laid thereon.

rlhe cars B ot' the train may be of any suitable center dump construction, those shown having an elongated body l() provided. at intervals with hoppers il, the bottoms ot which may be opened or closed by any suitable mechanism, not shown. Underneath the bottoms oi the hoppers 1l is arranged an endless traveling conveyor or belt F, which extends through the iull length oi the train, that shown passing at the rear end oi the train over a pulley or guide roller or rollers l2, and the conveyor or belt is provided at the front end ot the motor car C with an inclined portion 18, and at the front end of this inclined portion, the belt runs over a roller, drum, or other guide and driving device 14s 1When the apparatus is in use, the hopper bottoms are preferably opened, one or more at a time, so that the material is gradually discharged on the conveyor belt F, preferably in a manner suoli as to load the co-nveyor or belt up to the limit of its capacity, and the belt is driven by means of the motor contained in the motor car C. Another conveyor or belt G is arranged on the dump machine or car A and extends over a pulley or guide device 15 at the rear end of this car and inclines upwardly from this guide device to a guide device 16 at the other end of this belt. Beneath the raised end 16 of the belt G is another conveyor or belt H, the ends of which pass over rollers or guide devices 17 and 18. The belt H is adapted to be moved to different angular positions iii a substantially horizontal plane with reference to the track, so that the material may be dumped at the front end of the conveyor or belt H, either to the middle or to either side of the road bed. Means for accomplishing this result will be hereinafter explained.

It will be obvious that by providing a continuous belt extending through the length of a train or group of cars, that the belt may be more easily driven from a single source of power, and also that the material will be delivered with less loss or spill at the front end of the train. rlhe upper or load carrying run of the conveyor or belt is preferably supported at intervals by means of rollers or guide devices 19, and the lower run may, if desired, be also supported by similar rollers 19a. i

In order to enable the belt to operat satisfactorily at all times, whether the train is standing on a straight stretch of track or a curve, and also to avoid damage to the. belt while the train is passing around curves, such as necessitated by the sidings D', the following means for supporting the belt between adjacent ends of cars of a train may be employed, see particularly Figs. 5 to 7 The belt F is supported adjacent to each end of each car of a train by means of a series of rollers 2O mounted on a suitable frame or supporting bar 21, which is preferably curved so as to conform with the trough shape of the belt, and which is provided with any suitable bearings, not shown) on which the rollers 2() are journalled. 22 represent guide rollers arranged at opposite sides of the belt and journalled on brackets 23 secured on the ends of the frame members 21. The frame members 21 are mounted to rock from side to side, and for this purpose the frame members, in the construction shown, are provided at their middle portions with a bearing member 2a journalled on a subtantially horizontal and longitudinally extending pivot 25, so that the bearing members may swing laterally about the pivot 25, the pivot being supported by means of a pedestal 26 mounted on any suitablepart o-f a car, for example, on the end sill 27. Other means for pivoting the frame member 21 may be employed, if desired.

rlhe lower run of the belt F is guided downwardly at the ends of each car, so as to pass below the car coupler, and bears upwardly against rollers 30, each of which is journalled in the frame member 31, arranged adjacent to the end of a car. The frame member 31 is also arranged to tilt or swing laterally, and for this purpose in the construction shown, the frame member 31 is pivoted to swing about the axis of a pin 33. The lower frame member 31 also has guide rollers 35 at opposite ends thereof which are adapted to engage with the sides of the lower run of the belt F to hold the same in correct relation to the rollers 30.

The frames 21 and 31 are preferably connected so that they may be caused toswing simultaneously and for this purpose in the construction shown, the frames are connected at one side by means of a link 37, the lower end of which is pivoted at 38 on the lower frame 81, and the upper end of which is pivoted at 39 on the upper frame member 21. As a result of this connection between the two frame members, both frame members will be caused to swing siinultaneously about their pivots 25 and 33.

lf the material on the train or group of cars is being discharged while the train is standing on a curve, it is desirable that the edge of the belt at the outside of the curve should be at a greater elevation than the edge thereof at the inside of the curve, so Aas to best counteract the inertia! of the material, which might cause the material to be thrown off the belt toward the outside of the curve. Also when the train is rounding a curve, there is a tendency to stretch the edge of the belt at the outside of the curve, and to compress or buckle the other edge, and this tendency is also overcome by raising the outer edge and lowering the inner edge of the belt, and means are, therefore, provided for automatically changing the positions of those portions of the belt which extend between adjacent cars. In the construction sliown for this purpose a pair of cables 4,0 and 11 is provided for each frame member 21, the lower ends of these cables being secured to the frame members 21 adj acent to the opposite ends thereof. These cables extend upwardly from their connectien with the frame member 21, and pass over pulleys or guides 412, which are suitably secured to the frame or body of the c'ai on which the frame member 21 is mounted. rFliese cables, after passing over the pulleys 42, extend aci-ess a space between adja- CII cent cars and are secured at their other ends to the body of the next car. A similar pair of cables is provided for the frame member 2l olz the next car and pass over similar pulleys secured to the next Car, and the cables then entend across the space between adjacent cars, and are secured at their| other ends to the lirst mentioned car. In the particular construction shown, each ot the pulleys is arranged on a suitable bracket lll, and these brackets are provided with means 'for Ylastening the upper ends of the cables 4l() and al thereto.

It will be obvious that as two adjacent ears pass around a curve, the ends of the cars will be nearer to each other at the inside et the curve, and farther apart at the outside ot the curve. Consequently, as the portions oi the ends ot the cars which are `at the outside oit the curve move farther apart, the two pulleys l2 on that side of the car will move farther apart with the result ihat a larger portion of the cables at that side oit the car will be yrequired to extend across the space between pulleys and consequently parts of the vertical portions of the cables will pass over the pulleys l2 and thus raise the portions of the frame members 2l at the outside ot the curve. The corresponding moving together of' the portions of' the ends of the cars adjacent to the inside of the curve will cause the pulleys 42 on that side ot the car to move toward each other with the result that parts oit the horizontal portions of the cables pass over the pulleys and add to the vertical portions ot the cables, thus permitting the portions of the frame member 2l at the outside of the curve to lower. The parts will, therefore, assume the position shown in Fig. 7, in which the outside'oin the curve is supposed to be at the rient hand side et the ligure. Consequently,

the conveyor or belt is banked so that inlrtia or centrifugal V'loi-ce will not tend to throw any ot the material trom the belt.

Furthermore, when a train equipped with mechanism oli this kind is passing around a curve, the swinging of the frame members 2l and Bl, as indicated, will greatly Vfacilitate the passing` oi the belt around the curve, and will prevent the stretching of the edge of the belt adjacent to the outside orp the curve, since by the swinging ot' the belt supj'iorting iframe members 2l and 3l, the outer edge ot the belt is moved near to the center ot Yhe cars, and the belt is caused to assume the position which it would naturally assuine it bent into the corresponding curve. lhe tilting of the belt supporting frame members 2l and 3l is in proportion tothe radius ot the curve, since in the ease of sharper curves, or curves ot smaller radii, adjacent cars swing to a greater extent with reterence to each other, so that greater portions of the cables pass over the pulleys and increase the movement of the belt-supporting traine members. rlhe arrangement described also has the advantage ot making it possible to keep the car couplers t7 in their usual locations, since the two runs of the belt-pass above and below the couplers. lin conveyor' systems ot this kind as hereto- :tore inade, the couplers had to be positioned on. the bodjT portions ot the cars, in which positions the strength of the connectionv ot the couplers with the cars was inuc'h less than in the positions shown in the drawings.

The motor or driving car C may be equipped with a motor or power plant ofi' any usual er suitable type, that shown being in the torni ol an internal combustion engine 50, l*1 ig. 8, ot any suitable or desired construction, and having a suitable clutch mechanism, not shown, which is adapted to conn ct either a shaft 5l or a shaft 52 with the engine. rl ie shaft 5l is connected by means of beveled gears 53 and 5 with drive shafts extending lengthwise oit the car-C at each side thereof, and terminating in suitable worin or gear connections with the driving wheels and 57 of tne ear, see Figs. and 8, only one ot the drive shafts 55 being shown in the drawings. Slip joints 5S and universal joints 58 ot' any suitable construction are employed in the driving connection between the shalt 55 and the driving wheels 56 and 57.

When the shaft 52 is connected with the engine or motor 50, the power oiI the engine may be employed for operating the conveyor belt F. .ln the particular construction shown for this purpose, the shalt 52 is connected by a pair et universal joints 59 and 60 and an intermediate shaft to a short shalt 6l having bevel gear arranged thereon, and adapted to mesh with another bevel gear formed on the liront pnlley or roller let, so that by driving the pnlley or guide device 14C, the belt ll is driven throughout the length of the train. Any other driving connections between the motor and the belt and driving wheels et' the car C may be used, it desired.

The dump machine A is preferably' also mounted on wheels to inove along the track l), and is provided with an engine or motor,

, (not shown) olf any suitable kind contained within a cab or heuse G5, Fig. o. mounted on the l fame (36 of the car or machine il, and the engine or motor may be connected by ineansot any suitable mechanism, (also not shown) with the pulley or guide d .vice ltl ol the conveyor or belt 'G- 'lior driving the same, and also with the. pulley or guide device 17 oi the conveyor or belt ll for driving this dump belt.

The discharge belt H is mounted on a beam or frame member 89, which may be arranged in different angular positions, and

lor this purpose-the dump machine A is provided with a mast which is braced'by a suitable :trame work 7l, and the changing of the vertical angle ot' the dump conveyor or belt H is eltected by means of a hoisting tackle 72 connecting the mast 70 with the end o't the beam or arm G9, the tackle being preferably operated from the engine by means ot a windlass 73.

'In order to enable the arm 69 and the dump belt or conveyor H connected therewith to be moved to different horizontal positions, the inner end ot the beam 69 and the pulley or guide roller 17 are mounted upon a turn table 75, which is rotatable about a vertical pivot and which is mounted near the outer end of the platform 66 ot the dump machine A. The turning of the turn table 7 3 may be etlected in any suitable or well known manner, either by means ot hand power, or by means of power derived from the engine or motor, the driving mechanism thcretor not being shown.

ln order to level otl3 the material which has been dumped by the belt or conveyor ll, a leveling device 76 .is preferably provided, which is mounted to move lengthwise on the lower portion o't the beam 69, and which may be ot any suitable construction, tor example, in the form of a V-shaped plow which may move any material extending above a desired height laterally in opposite directions. The leveling device is adapted to be moved in either direction lengthwise ot' the beam by means o'l' one or more cables 77, the ends ot which are secured to the leveling` device 7 (3, and which pass over rollers or pulleys 78 and 79 journalled on the beam or arm G9. The cable 77 is also preferably driven by means of power derived from the engine or motor, the engine or motor beingconnected to the cable or chain 77 by any suitable mechanism, clutch or gearing, not shown, which is adapted to rotate the roller or pulley 78 in either direction. By means of the leveling device 7G, the road laid by the apparatus may be leveled ofi` without the use of hand labor.

ln the operation of the device, the material is placed on the hopper cars C and B by means ot the steam shovel E or by any other suitable means, and when a car or group ot cars is lilled, it is moved by its own power into substantially horizontal alinement with the end olf the dumping machine A. It two or more trains of cars are used ttor carrying the material to the dumping machine A, an empty train may be side tracked ou the switch D to permit the t'ull train to pass into operative relation to the dumping machine A.. After a train has been properly located with reference to the dumping machine, the power oit the engine 50 in the car C is applied to the operation of the conveyor or belt F extending lengthwise of the entire train, and the bottoms ot the various hoppers 11 may then be opened gradually, or a few at a time, so that a substantially uniform stream of material is fed by the belt F to the dumping apparatus. From this belt the material is deposited upon the belt G, which carries the material to the discharge or dumping belt H, and the material is linally discharged or dumped from the front end oit the belt. This last belt may be arranged at lany desired angle with reterence to the vertical or horizontal, so that the material may be dumped whatever it is deemed advisable. When the apparatus is used, for example, for the building of an embankment or dam, the leveling device 76 is use-d to form a level surface on the top ot' the embankment and additional track may then be laid on the newly formed portion ot the embankment so that the discharge or dumping machine A may be advanced.

lt will be understood, however, that the machine need not necessarily be used tor building` embankments or road beds, but can be used .for various other purposes, such, for example, as storing coal or ore, for loading grain, coal, ore and other commodities into vessels or elevators, and the discharge conveyor or belt H may be arranged to 'feed material into elevators, silos or other con tainers.

Among the advantages of my improved .apparatus are the tact that the supply train or cars C and D are not run up an incline over the dumping machine, which has the great advantage of conserving the amount of power required to operate the apparatus, and also very much simplifying the construction ot the discharge or dumping machine so that a high, long, and strong structure sullicient to support a train of cars is not necessary. By arranging the belt F throughout the length o'l the entire train or group ot cars, and in position to receive material from the hoppers ot the cars, 'the discharge of the material from the train is greatly facilitated and eliminates the need for a structure over the discharge machine which must carry the weight of the entire train. The means for supporting the belt between adjacent cars make it possible to operate the conveyor belt when the train is on a curve and prevent injury to the belt when the train rounds a curve. By means of the construction shown, a uniform supply ot' material maybe fed by the belt F by controlling the hopper bottoms, and by the use olf a plurality o'l hoppers, the belt is loaded only with the material actually carried thereby, since the material in the hoppers themselves is n-ot supported by the conveyor, but by the hopper bottoms themselves. By .arranging the belt F above and below the car couplers, these couplers can be arrange-d at uniform or standard elevation in which the cars may be coupled to any train or locomotiveo and standard car construction may consequently be employed.V The apparatus is less expensive to produce than others that have heretofore been devised, and .also operates more etiiciently.
