1 Claim.

This invention relates to a grain loading device designed for elevating and transporting grain from a stock pile to a truck, or from a truck into a railway car, and for all-other uses where movement or elevation of bulk grain or similar granular or comminutedmaterial is desired.

The principal object of the invention is to provide a grain loader of this type which will be conveniently portable; which can be attached to a truck or towing vehicle so as to trail therebehind; which can be quickly and easily detached from a tow vehicle and elevated'to any desired incline; and which will operate efficiently from a self-contained power unit.

Other objects and advantages reside in the detail construction of the invention, which is designed for simplicity, economy, and efficiency. These will become more apparent from the following description.

In the following detailed description of the invention, reference is had to the accompanying drawing which forms a part hereof. Like numerals refer to like parts in all views of the drawing and throughout the description.

In the drawing:

Fig. 1 is a perspective view of the improved grain loader in the traveling or towing position;

Fig. 2 is an enlarged, detail section, taken on the line 2-2, Fig. 1;

Fig. 3 is a similar detail section, taken on the line 3-3, Fig. 6;

Fig. 4 is a fragmentary detail view of an upper,

back-supporting band used on the improved loading device;

Fig. 5 is a perspective view of the improved grain loader in the operating position;

Fig. 6 is an enlarged cross-section through the loader, taken on the line 6-6, Fig. 1;

Fig. '7 is a fragmentary, detail view of an engine mounting employed on the loader; and

Figs. 8 and 9 are cross-sections, taken on the lines 88 and 9-9, Fig. 7.

A portion of an automotive truck or other vehicle is indicated at II]. The improved grain loader employs an elongated conveyor tube I I through which a hollow conveyor shaft I2 extends. A screw conveyor I3 of the flat, continuous helix type extends throughout the length of the shaft I2. The shaft I2 and the conveyor I3 extend beyond one extremity of the tube II so as to be rotatably supported in a ball bearing carried in a bearing plate I4 carried by arms I5 extending from the end of the tube II. The latter extremity of the tube forms the intake for the conveyor.

v The discharge consists of a' discharge opening I6 formed in the cylindrical wall of the tube II adjacent its other extremity. At the latter extremity of the tube the shaft I2 is supported in a concentric ball bearing in a bearing plate H. The shaft extends beyond the bearing plate I! to carry a V-belt driven pulley I8.

The power to rotate the shaft I2 issupplied from a small, internal combustion engine I9. The engine I9 is mounted on a platform 20. The platform is hinged upon two hinge hooks 2I which engage receiving openings in a clamping band 22 which is clamped about thetube II by means of a suitable clamp bolt 23. The platform may be supported at any desired angle by means of an adjustable brace 24 carried from a second clamping band 25 which is also clamped about the tube I I by means of a suitable clamping bolt 26. The brace 24 contains a series of holes 21 through which a supporting pin 28 may be passed to support the platform at any height. The power is transmitted from the engine I9 through an endless belt 29. The belt 29 extends from a drive pulley 30 around a pair of idler guide pulleys 3|, thence around the driven pulley I8. The idler pulleys are journalled on the extremities of a bent shaft 51 welded to an arm 58 bolted to the bearing plate IT.

The tube II is supported on wheels 32. The wheels are carried on stub axles 33 projecting from opposite extremities of an axle bar 34. An A-frame is built upon the axle bar 34 and comprises two side members 35 extending from opposite extremities of the axle bar 34 upwardly to a hinged mounting on a hinge bolt 36. The bolt 36 is carried in bolt ears 3! projecting from a third tube clamp 38 which is fixedly clamped about the tube I I between the engine I9 and the intake extremity of the tube I I.

A hinge ear 39 arises from each extremity of the axle bar 34. A brace leg 40 is hingedly secured to each of the ears 39 by means of suitable bolts 4|. The brace legs 4|] approach each other at their free extremities and are held in spaced relation by means of a cross bar 42. An axle bolt 43 extends between the extremities of the legs 40 and carries a tubular roller 44 provided with terminal flanges 45. This roller rides along a pair of parallel track members 46 which extend between supporting clamp bands 41 secured to the tube II.

A flexible cable 48 extends from the cross bar 42 to a winch 49 which can be rotated from a hand crank 59. The crank 59 may be locked against rotation by means of a ratchet latch 5I.

The intake extremity of the tube l I is provided with a pair of tongues 52 by means of which it may be attached to a draw bar 53 on the towing truck 10. When being transported, the roller 44 is allowed to move toward the discharge extremity of the tube so that the wheels 32 will approach the tube ll. At the extremity of. its travel the roller enters into vhooked holding members 54 which prevent the tube from bouncing upwardly while traveling. The tonguemembers are then.

attached to the draw bar 53 and the entire device is towed behind the truck I!) in a substantially level position.

When desired for elevatinggrain, it is detached from the truck I0 and the intake extremity is.

dropped into the pile of grain. The discharge extremity is elevated to the desired height bywithout departing from the spirit of the invention.

Having thus described the invention, what is claimed and desired secured by Letters Patent is:

Means for portably supporting a conveyor tube at an adjustable angle, comprising: an axle member; wheels supporting the extremities of said axle member; a side frame member mounted on each extremity of said axlemember and being inclined toward each other to a-common apex;

a hinge bolt extending through said apex transversally of said tube; a first tube clamp surrounding said tube and hingedly mounting said hinge bolt; a hinge ear arising from each extremity of said axle member; a brace leg hingedly secured to each hinge ear, said brace legs approaching each. other aththeirnfree extremities; a. cross bar maintainingssaidilatter'. extremities'in spaced relation; a shaft extending between said latter extremities below said tube; a tubular roller rotatably mounted on said shaft; terminal "fianges on the extremities of said roller; a pair of parallel roller tracks extending along said tube in contact. with. said roller between said terminal flanges; a .tube clamp at each extremity of said tracks holding the latter to said tube; a cable reel mounted on said side frame members; and

a cable-extending from said reel to said cross bar for drawing said brace legs toward said side frame members for elevatingsaid tube.
