This" improved *loaderI is. employed for removing 1 grain f orv Vother ,"freellowing"v material 'from a pile and'-transporting 'same' to a grain elevator .or :.othervdestination and includes a bin or. receptacle I carried by the chassis of a truck 2 whichmay be of any size found suitable and will be equipped with the usual engine and control mechanism.

The bin or receptacle projects rearwardly from the truck and its bottom isformed with a plurality of openings l through which grain passes when flowing from the bin. Guides 4 are carried by the bottom of the bin for directing material vthrough the outlet openings and, in order to close thev outlets, there has been provided a. closure plate or strip 5 which is mounted for longitudinal sliding adjustment under the bottom and jformed with openings 6 for registering with the outlets when the closure is in open position. By

grasping the depending hand hold I at the rear2 end of the closure, it may be easily shifted to open or closed position.

'The mechanism for delivering material to the `bin includes conveyors 8 and 9 and a trough or blade I0, the conveyors B extending rearwardly from the conveyor 8 at an upward incline at opposlte sides of the machine and the conveyor 9 vbeing disposed in front of and-over the trough I0 so Vthat when the blade or forward portion of the trough is thrust into a pile oi material, the conveyor 9 may shift the material longitudinally of the trough and deliver same to the lower rvi'ront ends of the conveyors l. The blade or trough I0 is formed of strong sheet metal and has an upwardly extending apron Ilia at its rear which bears against vertical posts II 'of frames I2 disposed at opposite sides of the truck or carriage 2 and having horizontal bars extending rearwardly from upper ends of the posts II and secured to upstanding posts I3 at forward corners of the truck chassis 2. Braces Il extend rearwardly from opposite ends of the trough I0 and its apron and are secured to a cross bar I5 pivoted at its ends to rods I6. These rods are slidably received in bars 4I'I which are pivoted at their rear ends to barsor beams I8 carried by hangers I9 under the chassis of the truck. It will thus be seen thatthe trough I0 may be shifted vertically to adjusted positions. I

Thelconveyors 8 have troughs provided wit side bars I9 and bottoms 20 which are formed of sheet metal and, for a portion of its length, each trough is provided with a hood 2| extending to the top o1 the trough and extended downwardly to form a spout 2|' through which the grain or'other material is discharged into the bin I. Uprights or posts 22 support the rear ends of the troughs and carry bearings 23 through which a shaft 24 is rotatably mounted. This Shaft Carries sprocket Wheels 25 about which are trained the endless sprocket chains 28 of the conveyors. The chains 28 extend longitudinally of the troughs and, at their lower ends, are trained about sprocket wheels 21 carried by a shaft 28 which extends longitudinally of the trough I8 and constitutes a shaft for the conveyor 8. The conveyor 8 consists of a plurality of screw conveyors 28 and 88 which are carried by the shaft 28, and attention is called to the fact that the screws 28 are disposed between the conveyors 8 whereas the screws 88 are disposed outwardly of the conveyors 8. The helical bladesA of the screws are pitched in oppositeA directions, as shown in Fig. 3, so that the two screws 28 feed grain toward the two conveyors 8 and the screws 38 feed grain inwardly of the trough I8 toward the conveyors 8 with which they cooperate. The shaft 28 is rotatably mounted in bearings 8| at the front ends of bars 82 which extend longitudinally in the troughs of the conveyors 8 and at their rear ends are pivotally mounted by shafts 88 carried by bearings 84 mounted on the side bars I8 of the conveyor troughs. The shafts 88 also carry rollers 88 for separating upper and lower flights of the sprocket chains 28 and guiding movement thereof during operation of the conveyors. Cross bars 88 hold the bars 82 spaced from each other transversely of the conveyor troughs 28. Blades 81 are Vcarried'by the sprocket chains 28 and when the conveyors 8 are in motion, these blades serve to move grain upwardly along the bottoms of the troughs 28 to the spouts 2|.

In order to operate the conveyors 8, there has been provided a power unit 88 which is mounted on the truck transversely thereof and is provided with a pulley 88 and having a gear shift controlled by the usual lever 48. so that the speed at which the pulley rotates may be regulated. A shaft 4| is rotatably mounted through bearings 42 carried by posts or uprights 48 and this shaft carries a pulley 44 in order that rotary motion may be transmitted to shaft 4| by a belt or belts 48 trained about the pulleys 88 and 44. A sprocket wheel 48 is also carried by the countershaft 42 and about the sprocket wheel is trained a chain 41 which extends upwardly and is trained about a sprocket wheel 48 carried by the shaft 23. Since the pulley 4| is of appreciably greater diameter than the pulley 88, a speed reduction will be accomplished and the propellers 8 and 8 will be operated ata desired speed, the conveyors 8 being driven from the shaft 24 and the conveyor 8 by the chains 28 and sprockets 21. y

During use of the loader, it is desired to vertically adjust the scoop or trough I8 so that it may enter a pile of grain at the floor level or at any other desired level. Itis also at times necessary to raise the scoop in order to compensate for sliding of the grain. To do this, there has been provided a lever 48 which extends longitudinally of the truck and projects from the front end thereof midway its width. This lever is pivotally mounted between arms 88 projecting forwardly from a cylinder 8| mounted on a bracket 82, and, at its inner rear end, the lever is formed with a depending arm 88 formed with a slot 84 in its lower portion to receive a pin 88 carried by a clevis 56 at the front end of a piston rod 51. The piston rod projects forwardly out of the cylinder 5| and, at its rear end, is fixed to a piston 58 which is shiftable longitudinally in the cylinder by water, oil, or other fluid medium which enters and leaves the cylinder through pipes 88 and 88. The pipe 88 communicates with the upper end of a reservoir 8| and pipe 88 communicates with a rotary pump 82, a pipe 88 be ing provided for connecting the pump with the lower end of the reservoir. The pump is driven from the shaft 4| by a belt 84 trained about a pulley 88 carried by the shaft, and a pulley 88 carried by the shaft .of the pump. By adJusting the valve or valves of thepump, the direction in which it operates may be controlled and the liquid delivered to the cylinder in such manner that the piston will be shifted either forwardly or rearwardly in the cylinder. When the piston is moved in the cylinder the lever 48 will be tilted about the'pin 88 and scoop I8 will be "shifted vertically through the medium of a bar 81 pivoted at its upper end to the front end of the lever and having its lower end xed to .the scoop midway the ends thereof. Since the ttached, the cables extending ldownwardly and having their lower ends connected .to lugs or brackets 1| carried by inner ones of theA arms or bars 82. When the shaft 18 is turnedthe cables will be' shifted longitudinallyy 4and the shaft 28 and screws carried thereby raised or lowered to dispose the screws in proper relation to the scoop. A shaft 12 which extends longitudinally of the loader and has a wheel 18 at its rear end, is rotatably mounted through a bearing bracket 14 and has its front endrotatably received in a gear housing 18 which is also mounted about the shaft 88 and encloses a worm and worm gear so that when the shaft 12 is rotated, rotary motion will be imparted to the shaft 88 and the quadrants 88 swung vertically to raise or lower the bars 82 and shaft 28. It will thus be seen that the screws 28 and 88 may be vertically adjusted and disposed in such relation to the scoop that grain will be moved along the scoop during operation of the conveyor 8 and onto lower ends of the conveyors 8. .The conveyor 8 will, therefore, operate very efficiently to remove grain from a pile and deposit it upon conveyors 8 which carry it upwardly and deliver it to the bin l. l Having thus described the invention, what is claimed is: l
