Claims. 1`

This invention relates to conveyors and more particularly to a conveyor by means of which grain, gravel, and other loose running material may be removed from a pile of such material and delivered into a truck or vother vehicle in which it is to be transported from one place to another.

Another object of the invention is to pro-vide a conveyor including a p'ort'alble frame or carriage 'adapted to be hitched back of a vehicle and the vehicle employed as means for backing the conveyor into -a pile of material which will then be gradually removed from the pile and delivered into the vehicle which will be in position to receive the material from a spout at the front end of the conveyor.

Another object of the invention is to provide a `conveyor so mounted upon a portable carriage that it extends forwardly at an upward incline with its front end portion projecting from the carriage in such an elevated position that it will overhang alvehicle and material may :dow from a spout at the front end of the conveyor into the vehicle.

Another object of the invention is to provide a conveyor wherein a motor for driving the endless ca-rrer of the conveyor is mounted upon a carriage over which the conveyor is sup-ported, there being provided wheels for supporting the carriage, and one wheel being a castor having improved actuating means for shifting the rear portion of the carriage vertically, to permit shifting of thecarriage when so desired.

Another object of the invention is to provide a conveyor which is strong, easy to operate, and notrliable to get out of order.

rihe invention is illustrated in the accompanying drawings wherein:

Fig. 1 is a side elevation of the improved conveyor.

Fig. 2 is a top plan view thereof.

Fig. 3 is a sectional view taken along the line '5i-3 of Figure 2.

Fig. 4 is a sectional view taken along the line ei-'d of Figure 1.

Fig. 5 is a sectional view taken along the line '5-'5 of Figure 1.

This improved conveyor or loader has `a carriage i including side bars 2 across the front ends of which there is mounted a cross bar or aide 3 carrying wheels 4. The front end of the carriage also carries a tongue 5 which `projects forwardly therefrom and at its iront end is equipped with a clevis for connecting the tongue with a vehicle to be loaded. It will thus be seen that the carriage may `b'e drawn forwardly back of the vehicle from one place to another and when the loader is to be used it may be backed into a pile of grain or other loose running material, and the vehicle will be in position in front of the loader to receive material removed from the pile.

lA castor I supports. the rear portion of thev carriage and, has its shaft B extending vertically and rotatably mounted through a sleeve or bearing 9 carried by a cross bar Ill. The cross bar extends transversely of the carriage and its ends are slidably received in open inner sides of channel beams Il extending vertically between the side bars 2 of the carriage and side portions of the carriage. Plates I2 and I3 mounted in the beams Il limit vertical movement of the cross bar in the beams. A shaft I4 is rotatably mounted across the carriage in bearings I5 and carries arms I6 which project forwardly from the shaft and pass through slots II formed vertically through the cross bar Il). At one end of the shaft is a lever I8, and when this lever is swung forwardly the carriage will be shifted upwardly to raise the carriage until the cross bar I0 engages the plate I3 instead of the plate I2. The loader may then tbe freely drawn forwardly back of a vehicle or backed to a position in operative relation to a pile of material to be loaded into the vehicle. The tongue may then -be released from the vehicle and a number of vehicles successively moved into position in front of the loader for loading of the vehicles.

Over the carriage is a conveyor frame I9 having upper and lower side bars 2D and 2| held in spaced relation to each other by bars 22. A pan Y 23 is carried by the upper side bars 20 and through this pan extends the upper flights of upper conveyor chains 24 which carry cross blades V25, The lower rear end of the conveyor frame is anchored to the rear end of the carriage by `blocks 26 and Yfrom this end of the frame project `arms 2l with which a shaft 28 is rotatably connected. This shaft carries sprocket wheels 29 about which .the chains 24 are trained and upper vport-ions of the chains are trained about sprocket wheels -30 carried by a shaft 3| which extends transversely through a hood 32 which is slidably engaged with the side bars of the inclined conveyor frame and has its ends rotatably mounted in [bearings 33. The bearings extend longitudinally of the conveyor frame at opposite sides thereof and carry 'threaded rods or bolts 34 which slidably pass through blocks 35 and carry nuts 355 by means of which 'the bearings may .be-shifted longitudinally of the conveyor frame .and the Vchains tightened. The hood is open at its rear end and tapers towards this end and forms a spout through which the grain or other material will be discharged into the vehicle over which the conveyor frame projects. Props 31 are provided to support the conveyor frame in the inclined position and the beams l I aid in supporting the conveyor frame.

In order to drive the conveyor mechanism there has been provided a motor 38 which is mounted upon the carriage adjacent the front end thereof and Carries a pulley 39 about which are trained belts 4D which extend upwardly from the motor and have their upper portions trained about a large pulley 4l carried by a shaft 42 which is rotatably mounted transversely of the conveyor frame and at its other end carried a sprocket wheel 43. A sprocket chain 44 is trained about this sprocket wheel and extends towards the rear end of the conveyor frame from its rear portion trained about a large sprocket wheel 45 carried by shaft 3l. As the shaft 3i turns the chains 24 will be moved longitudinally of the conveyor frame and as the blades 25 move through the shoe 46 projecting forwardly from the `front end of the conveyor frame a portion of the pile of grain into which the shoe is embedded will be taken up by the blades or plates and carried towards the upper front end of the pan 23 from which it is dumped into the hood or spout 32 and then discharged therefrom into a vehicle over which the hood is disposed. The shoe has side extensions forming troughs 4l! in which operates screws 48 which are right and left hand screws and move grain in the pile inwardly towards the shoe so that an ample supply of grain will be provided for engagement by the blades 25. If so desired an attendant may shovel grain from the pile into the troughs l and the shoe and when it is necessary to do so the loader will be thrust rearwardly into the pile of grain. The lever i8 extends upwardly at one side of the conveyor frame and to its upper end is secured a clevis 49 carried by a cable 50 which is wound about a drum 5i secured upon a shaft 52. This shaft extends transversely of the conveyor frame and is rotatably mounted through bearings 53 and adjacent the drum carried a ratchet wheel 54 engaged by a latch 55 so that when the handwheel 55 is turned to rotate the shaft and wind the cable upon the drum the cable will be held wound upon the drum and the lever i8 held in a position to which it has been pulled forwardly and the carriage held in a raised position with the shoe i5 and the troughs 3 01T of the ground. The loader may then be shifted rearwardly into a pile of material or drawn along the ground behind a truck or other vehicle. When the point at `which the loader is to be used is reached the latch 55 will be grasped and drawn upwardly to a position in which the ratchet 54 will be released and the cable may unwind from the drum and allow the carriage to settle to a lowered position.
