*igure 8 is a sectional view showing the lei is a fragmental vertical section of the conveyor mechanism and attendant oneend 2 of thevframe 1. v The bracket 3 has bearings 4. The bearings 4 are secured at 5, as shown in Figure 1,to a hopper 6. The" 'hopper 6 is secured atv 7 (Figure 1) to the inner end of the bracket 3. The hopperv 6 has an' inclined bottom 8 (Figure 3) which slopes toward an opening 9 in the rear Wall of the hopper 6, the opening 9 being ycontrolled by a vertically slidable gate 10 on the rear wall of the hopper.

A bearing 11 (Figure 1) is mounted on one end of the4 hopper 6. A transverse shaft 12 is journaled in the bearings 11 and 4. An upwardly extended and rearwardly inclined casing 14 isinounted to swing on the shaft/12. The .casing14 h as adepending discharge spout 15. The lower end-of the casing 14 is open, asv shown at 16 in Figure 9,- opposite to the opening 9 in the rear wall -of the hopper 6. There are "adjustable bearings .18 at the upper end ofthe casing 14. A shaft 17 is mounted Vin` the bearings 18. There are pulleys 19 Ion the shafts 17 Vand 12. VA conveyor 2O is engaged with the pulleys 19 and operates in the casing 14, as shown in Figure 9L The shaft 12 is united operatively by a belt and pulley connection 21, or in any other suitwith Ya transverse Vdrive shaft 22, which isjournaled for rotation in the frame Y 1. The drive shaft 22 carries grooved wheels 23 located within the frame 1. There is a l friction disc 24on the shaft 22, outwardly of the Vframe 1 (Figure 1).

A lever 25 is fulcruined at 26 on the hopper g 6 or elsewhere. A ldepending angle bracket 27 (Figures 7 and 8) Vis pivoted at 28 to the lever 25. The braclret 27 saddles the shaft 22 and is'adapted to engage a bearing 29 on the shaft 22. The bearing 29 can slide lengthwise of the shaft`22, and' the'shaft 22Ycan rotate in the bearing 29.4 l f l The lnumeral 30 (Figure 6) Ymarks a shaft extended longitudinally of the frame 1, with a slight inward inclination. The rear end of the shaft 30 (Figure 6) is looselyl held at `ties 47 shown in Figureil. ofthe tracks 4,@v (Figure 3) `iiexible element 54 3l for rotation in the shiftable bearing 29. There is a friction wheel 32 on the shaft 30, adjacent to the bearing 29. The friction wheel 32 may be brought into engagement with the friction disc 24 on the shaft 22.

By means of a universal joint 33, the forward end of the shaft 30 is connected to a shaft 34 journaled in bearings 35 on the frame l. The shaft 34 has a worm 36 (Figure l). The worm 36 meshes with a worm wheel 37 (Figure 4) on a transverse shaft 38 mounted to rotate in the frame l.

There are drums 39 on the endsof the;

shaft 38. Flexible elements 40 are secured to the drums 39 and are wound thereabout.

The flexible elements Y40- extend ifiwardlyl (Figure 2) around idlers 4l j ournaled on the lower ends of posts 42. The posts 42 are held by a supplemental frame 43 (Figure en the forward end of the main frame 1L Froin tlie idlers 4l, the lexible elements 4() extend up; wardly around pulleys v44 journaled on the posts 42 near to the upper ends of the posts. From the pulleys 44,a the flexible elements 40 are extendeddownwardly.

. kThe lower @nds of the flexible elements 40, are united to a on the forward ends ofl trouglrshapedtracks 46 (Figure 5). The

tracks 46 are united by The rear ends are mounted t0 swing on a support or rod 48/ which extends across the frame l. The tracks 46, therefore, are mounted for vertical swinging Inovement on the frame l.

Near to the inner end of the tracks 46 is located a shafti49 which is journaled in the framel'.- Theshaft49 carries grooved wheels',

50. Figure l shows that the wheels 5Qand23 are aligned to form a seat in which the rear wheels of 'a truck fulc'rumed at 5 3 on ed to cooperate with the brake disc 5l. 'A is connected to the upper end of the brake lever 52. The flexible elef ment 54 is extended forwardly, and is rove through a hole 55 in one-of the posts '42.

In practical operation, the tracks 46` are swung downwardly on their pivotal meunting 48 from the the forward ends of the tracks rest on the ground.y A loaded truck is run upalongv the tracks 46, the power-driven truck coming to a seat between the groeved wheels 50 and 23. lV hen the engine on the truck is put into operation, to turn the wheels of the truck, the wheels 23 will rotate the shaft 22.` The lever 25 is swung inwardly, the bracket 27 sliding to the rightin Figure 7 and carrying the bearing 29 to the right in Figure 7, the friction wheel 32 of the shaft 30 being brought into Contact with the friction disc 24 on the shaft 22. The shaft 22 is connecting rod 45 mounted (not Shown) 'are adapted to be received.V There is a brake disc 5,1 onV the shaft 49. A brake lever 52 (Figure 2)l isl the frame l and is adaptposition ofv Figure 2, until Y wheels of the.

being rotated, it will be recalled, by the truck wheels, and rotation will be imparted to the shaft 30 by the friction disc 24 and the friction wheel 32. The universal joint 33 transmits rotation to the shaft 34, and the shaft 38 is rotated through the instrumentality of the worm wheel 37 and the worm 36. Vhen the shaft 39 is rotated, the flexible elements 40 are wound upon the drums 39 and the forward ends of the tracks are raised, the tracks swinging upwardly on their pivotal mounting 48. In this way, the tracks can be elevated so that the load'willslide out of the truck into the hopper 6, the material following the inclined bottom 8 of the hopper 6 aridpassingm'tlirough the/opening 9, into the fieldof operation of the conveyor 20.

' vThe operator reverses the driving gears in the truck, reverserotation is imparted to the wheels"23 'aid' to" the shaft 22, and the truck is lowered. By means of the tiexible element 54, ,the brake lever 52 can be applied to the brake dise wheels 5,(1 against rotation. Itis desirable. or necessary to hold the wheels 5 0 against rotation, so that the truck wheels,V can climbover the wheels 5,0, and onto the tracks 46.

From the shaft 22, rotation is imparted to the shaft l2' by the belt drive 2l or itsl equiva lent. The shaft l2 operates the conveyor 20 and the material is` carried upwardly and discharged through the spout l5.` The con,- veyOr casing 14 may be swung to various ane gles Q n the shaftk 12, as required, andmay be held by any suitable means, forming no part of thisnvention, in the position to which it hasbeen adjusted.

Having thus describedv the invention, what isclaimedisgz-r In a device of the class described, a substantially horizontal frame, posts at one end of the frame, upper and lower pulleys jour naled on theposts, a vehicle track mounted at its inner end en .the frame for vertical swinging movement, a first shaft journaled on the frame and located intermediate the ends of the track, iexible elements disposed at the sides of the track, being wound about the ends of the firstA shaft, extended along the sides ,ofthe frame, upwardly about the lower pulleys and downwardly about the upper pulleys, the flexible elements being secured to the outer end of the track, a second shaft and a third shaft journaled vone infront of the other on the frame and in front of the first shaft, wheels for engagement with the Wheels of avehicle and mounted on Jthe second and third shafts at the inner? end of the track, load-elevating mechanism operatively connected with the third shaft, a brake under the control of an operator and engaging the second shaft,a friction wheel on the third shaft,'a laterally flexible shaft, afriction wheel on the laterally flexible shaft, means for supporting the latthe flexible velements erally flexible shaft at one end for rotation on the frame, a Worm and pinion drive connecting the laterally flexible shaft with the first shaft, means for supporting the laterally flexible shaft for rotation and for lateral movement on the third shaft, and means Jfor moving the laterally flexible shaft laterally, at the will of an operator, to bring the J`riction Wheel of Said shaft into and out of engagement with the friction Wheel on the third shaft.

In testimony that I claim the foregoing as my own, I have hereto affixed my signature.
