1 Claim. (Cl. 198--233) The present invention rel-ates to new and useful improvements in loading elevators and more particularly to a loading elevator for baled hay and similar bulk materials.

An important object of the present invention is to provide a trailer frame on which the elevator is carried and providing a power plant carried directly by the elevator for operating the same and manually operated means for vertically adjusting the delivery end of the elevator.

A further object is to provide an apparatus of this character of simple and practical construction, which is strong and durable, efiicient and reliable in operation, relatively inexpensive to manufacture and otherwise well adapted for the purposes for which the same is intended.

Other objects and advantages reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming part hereof, wherein like numerals refer to like parts throughout, and in which:

Figure 1 is a top plan view.

Figure 2 is a side elevational view showing the elevator in its lowered position when not in use.

Figure 3 is a similar view showing the elevator in its raised position.

Figure 4 is a vertical transverse sectional view taken substantially on the line 4-4 of Figure 3, and

Figure 5 is an enlarged fragmentary sectional view taken on a line 5-5 of Figure 3.

Referring now to the drawings in detail wherein for the purpose of illustration I have disclosed a preferred embodiment of the invention the numeral 5 designates a trailer frame to one end of which an axle S is secured with the wheels 7 journalled on the ends of the axle. The other end of the frame is provided with a tractor hitch 8 of conventional construction and by means of which the trailer may be detachably connected to a draw-bar 9 of a tractor or other towing vehicle.

The front end of the frame 5, adjacent the hitch 8 is provided at its side edges with upstanding supports til suitably braced as shown at H. The receiving end of a loading elevator frame i2 is pivoted to the upper end of the support it by pins or the like l3 for vertical swinging movement of the delivery end of the elevator.

The elevator i2 extends longitudinally above the frame 5 with its delivery end projecting rear wardly of the wheels l, the elevator being substantially balanced on the wheels.

The elevator frame l2 includes spaced parallel 2 longitudinally extending frame members 14 suitably braced as shown at I5, the side frame members having side rails l6 supported in an elevated position thereon by posts El and braces 13. Po sitioned between the side frame members 14 are substantially flat spaced parallel tracks'lll, the

tracks being suitably secured to the cross bracing IS.

A front transverse shaft 20 is journalled at the front ends of the side frame members l4 and a rear transverse shaft 2| is journalled at the rear end of the side frame members M. A sprocket 22 is carried by the shaft 28 and a sprocket 23 is secured to the shaft 2|, the sprocket having an endless conveyor chain 24 trained thereon. The chain 24 is driven by the sprocket 23 and shaft 2! by means of an electric motor 25 supported on a bracket 2% beneath the rear end of one of the side frame members [4, the motor driving the shaft 2! through a series of belts or chains 2'! and reduction pulleys or sprockets 28.

A plurality of conveying lugs or prongs 29 are suitably secured at longitudinally spaced intervals to the chain 24 whereby bales of hay or other material deposited on the elevator at the receiving end thereof will be conveyed longitudinally of the elevator.

An idler sprocket 35 is suitably supported beneath the elevator !2 over which the lower flight of the chain travels to remove slack therein.

A pair of arms 3! are provided with collars 32 at their front ends for pivotally mounting the arms on the axle ii, the arms being connected to each other for uniform raising and lowering movement by cross members 33; Grooved rollers 34 are journalled at the rear ends of the arms to travel under the lower edges of the frame members l2.

A cable 35 is secured at one end to the rear end of one of the arms 3! and extends forwardly under the elevator for winding and unwinding on a drum 36 secured to a shaft 3'l journalled at the front end of trailer frame 5 and manually operated by a handle 38 and gears 39.

A pair of props 49 rise from the axle 5 having reduced vertical pins El at their upper ends to enter recesses 32 in the underside of frame members l2 to support the elevator in a lowered substantially horizontal position on the trailer when not in use and while being transported from place to place.

In the operation of the device, the rear or delivery end of the elevator is raised or lowered into a desired vertically adjusted position by the drum 3% and cable 35 and bales of hay #33 or other ma- 8 terial received on the lower front end of the elevator is conveyed rearwardly by the motor driven chain 24 and delivered at its upper end for storage or stacking.

In view of the foregoing description taken in conjunction with the accompanying drawings it is believed that a clear understanding of the construction, operation and advantages of the device \Vill be quite apparent to those slcllled in this art. A more detailed description is accordingly deemed unnecessary.

It is to be understood, however, that eventhough there is herein shown. and. described a preferred embodiment of the invention the same is susceptible to certain changes fully comprehended by the spirit of .the invention as; herein.
