2, seems The bearings 7 receive an upper shaft 10, which extends entirely across the conveyor frame and which receives upper sprocket wheels ll. of a plurality of endless conveyors. The endless coi'iveyers, which may be of any desired number, are located at opposite sides of the top and at the ccntcr ol' the space between the rails. The side conveyers are located above the rails and project beyond the same. In the accompanying drawings three are shown, one being located at the center of the front end of the car, and the other two being arranged at opposite sides of the central conveyor. The conveyers are provided with approximately triangular buckets 12, suitably secured to endless sprocket chains 13, which are arranged in pairs and which extend down wardly'andforwardly llOlll the upper sprocket Wheels ll to lower sprocket wheels 14. Each endless conveyer is provided at its lower end with an independent or separate shaft 15, journaled in adjustable bearings 16 to enable the slack in the chain of any one of the conveyors to be readily taken up. The adjustable bearings 16 are slidable in oblong frames or pedestals 17, which are arranged at an inclination and which extend a sufficient distance below the front of the main or car frame to enable the endless conveyors, when operating on a loose bank of material, to clear a space in advance of the front truck, of sutlicient depth to receive the cross-ties and rails for extending the track in advance of the ma chine.

In practice the track will be laid in four or live foot sections, and there will be sutlicient space between the front wheels and the elevators to permit a section of track to be placed in position for cxtendiin, the track already laid. The central conveyor, which is arranged between the rails, and the side conveyors, which project laterally beyond the rails, are adapted to not only load the material upon the car, but they also clear a.

7 space sufficiently large [or the machine to l'oll up its to engage anyloosc nnncrialm bulk, such as stored coal,

loose earth, or the likc, and the buckets arc adapted to carry the material upwardly to an adjustable spout or chute. The buckets, in traveling over the upper end of the convcycr frame, are invcricd to dischargc their contents into a hopper shapcd uppcr section 20 of the spout or chute.

The hopper shaped upper section 20, which tapers downwardly is set at an inclination and is secured at its upper end 'to the conveyor frame. The upper end of the section 20 is provided with opposite laterally extending attzurhment flanges 2i, which are bolted to the adjacent portions of the conveyor irame. The lower end of the upper section 20 is provided with a depending cylindrical neck 22, which fits in a rotaryelbow 23, having-a vertical upper portion and an inclined lower portion. The upper vertical portion receives the depending neck 22 o)": the hopper shaped section 20, and the neck and elbow re provided with collars 2i and 25, arranged exteriorly oi the said parts and provided with horizontal annular flanges, which in, against each other, whereby the elbow is capable of free rotary movemo nt on the neck.

The elbow is supported by a vertical pivot, which has a round upper end 27 to fit in a depending socket 28 of the elbow. The depending socket 28, which is arranged vertically, as clearly illustrated in Fig. 4 of the drawings, is provided with an inclined attachment plate or portion, which is bolted or otherwise secured to the elbow. The upper end 27 is solid, but the rest of the vertical pivot 26 is preferably tubular, and is provided with a threaded lower end 29; which is screwed into a threaded socket 30 of the car frame.

The threaded socket may be mounted on the car frame in any desired manner, and the vertical pivot is supported at an intermediate point by braces 31 and 32,

tion 36 to the elbow. The lower adjustable sec-- tion 36 oi the spout or chute is arranged at an inclina- "tion and is provided with flared upperend 37 to receive the lower end 01 the elbow, and itis provided at the bottom of the flared portion with a slot to receive the projecting eye 34, and it has eyes 38 at opposite sides of the slot for the reception of the pivot or pintle. The lower inclined section36-oi the spout is adapted to swing upwardly and downwardly, and is adjustahly supported by means oiE brace, composed of upper and lower rods 39 and 4G and a connecting turn buckle 41. The upper rod 39 is provided at its upper end with an eye 42, which is linked into a swiveled eye 43, whereby the brace is adapted to swing freely, when the elbow and the lower section 36 are moved horizontally. The

swivcled eye 43 is provided with a pivot 44, which is lot arranged in perforation or hearing opening of a substantially (I-shaped bracket or member 45. The sub stantiaily (I-shaped bracket or member if: is mounted on the upper hopper shaped section 29 of the spout or chutc, and it has terminal projecting portions secured to thc same. The lowcr end oi the lower rod -10 ispro- 'ided with an eye ib, which is linked into an eye 47' of the bottom section 36 of the spout or chute. The inclined lower sect ion is adapted to swing horizontally to extend it in any direction, and it is also adapted to be readily raised and lowered by means of the adjust ablc brace 41, The lower section 36 maybe made of any desired length, and the conveyor is adapted to deliver the material into a car at the ccntcr or either end thereof, and when lilling a car at the rear end thereof, the track on which the machinc travels may be utilized for ninning the cars to bc tilled to and from the machine.

The machine may be propelled forwardly or back- Wardly and the conveyors operated by any suitable motor, which is designed to be coupled t9 a transverse crank shalt 4S, and the latter carries a sprocket pinion 49, which is connected by a sprocket chain 50 with a large sprocket whehl 51 of a counter-shaft 52. The

gears may be'oi any relative size to securethe desired a spur pinion 53, which meshes with a large spur gear 54 of a main transverseshait 55, from which motion is communicated either to the car or to the endless conveyers.

Mounted on the transverse shaft is a slidable cli'tch section 56, having opposite clutch faces 57 and 58, which are adapted to engage corresponding clutch sections 59 and 60 of the sprocket pinions or gears 61 and 62. The movable clutch section 56 is slidably interlocked with the shaft, and it may be engaged with either of the clutch sections 59 and 60, or may be arranged at an intermediate point. as illustrated in Fig. 3 of the drawings. The clutch sections, as clearly illustrated in Fig.

, 3 of the drawings, are provided with projections and recesses to enable the sections to interlock when engaged with each other, but any other form of clutch may be employed, if desired. The clutch is operated by means of a shifting lever 63. mounted on a longitudinal rock shaft 64, which is provided at its front end with a. pair of upwardly extending arms 65, located at opposite sides of the slidable clutch section, as clearly shown in Fig. 6 of the drawings. The shitting lever (53 carries a spring actuated detent or dog (57. arranged to engage a notched segment (38, and adapted to be operated by a latch lever iii), mounted on the shifting lever adjacent to the upper end thereof. The notched segment '68, which is suitably iixed to the main or car frame. is provided with central and side notches, for holding the slidable clutch section in engagement with either of the other clutch sections, or ior maintaining the slidalile clutch sections out of engagement with both of the other clutch sections, as clearly shown in'l ig. 3 of the drawings, whereby the motor may operate without actuating either the car or the conveyors.

Thennain transverse shaft is connected with the rear axle 70 oi the front truck by means of sprocket gcaring, consisting of sprocket wheels 71 and (52, mounted respectively on the axle 70 and on the main transverse shaft and receiving a sprocket chain 73. The front axle 74 of the rear truck is positively driven by a-SPIOCkQt gearing connecting the front axle of the rear truck to the rear axle of the front truck, and consisting of sprocket wheels 75 and 76. and a sprocket chain 77.

The main transverse shaft is connected with the upper shaft of the series of the endless conveyors by means of sprocket gearing, consisting of an upper sprocket wheel 78, the lower sprocket gear (ii and a sprocket chain 79. This gearing is located atone side of the machine, as clearly illustrated in l ig. 2 of the drawings,
