3 Claims.

Thi invention relates to an apparatus for building terraces in fields and the like, the invention being mainly used in soil conservation service, the general object of the invention being to make the apparatus in the-form of an attachment for a tractor or truck with means whereby as the vehicle travels along a field a plow will lift dirt from a point at one side of the vehicle and deposit it on a conveyor which will carry the dirt to the opposite side of the vehicle to build the terrace.

Another object of the invention is to make the parts adjustable so that the attachment can be raised into inoperative position so that it can be transported with the vehicle along roads and the like without-injuring the roads.

Another object of the invention is to so form the attachment that no wheels are used which would injure the terrace being built.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claims.

In describing the invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which:

Figure l is a fragmentary top plan view showing the invention on a tractor.

Figure 2 is an elevational view of Figure 1 looking toward the left hand. side thereof.

Figure 3 is a rear view of Figure 1.

Figure 4 is a section on the line 4-4 of Figure 3.

Figure 5 is a view partly in section and partly in elevation of the drive roll for the conveyor belt, the pulley attached to the roll and the supporting shaft for such parts.

Figure 6 is a view of the arm for adjusting the apparatus.

The letter T indicates a tractor though this may be a truck and the letter :1 indicates the take-01f shaft at. the rear of the tractor. In carrying out the invention a conveyor frame F is provided for extending across the rear of the tractor and an arm I is connected to one side of the tractor for pivotal movement as by a bolt 2 and a block 3 is pivoted to the rear end of the arm as shown at 4 so that the block can rock about a laterally extending and horizontal axis. The rear end of the block is forked to receive a lug 5 on the front edge of the frame F at one end thereof and a bolt 6 passes through the prongs and the lug or bracket so that the lug or bracket can move about a vertical pivot.- A large bracket 1 is attached to the opposite side of the tractor from that side to which the bracket or arm I is connected and this bracket 1 is formed with an upstanding part I to which a rearwardly extending horizontal shaft 8 is connected. This shaft passes through a roll 8 having reduced ends IE! which form trunnions which are rotatably arranged in side members of the frame F and a pulley H is connected to theinner trunnion, a belt l2 passing over this pulley and over a small pulley l3 on the take-off shaft a. Thus when the shaft a is in motion the pulley II will be rowhich passes over the roll 9 and over a roll 15 adjacent the other end of the frame F. Small supporting rolls it are carried by the frame and over which portions of the belt pass. A small frame IT is attached to-the left hand end of the conveyor frame and rotatably supports a disk plow I 8 which is so located that as the tractor travels along this plow will make a furrow inthe ground alongside of the tractor and throw the soil upon the conveyor belt so that the soil or dirt is conveyed upwardly and across the rear end of the tractor. This dirt is deposited upon a second conveyor 19, the frame F of which has the arms 20 attached to its side-members adjacent the inner end thereof and these arms pivot on the shaft 8 so that the frame F" can be raised and lowered. The frame F is held in an outwardly and downwardly-sloping position normally by portions of the arms engaging-the stop blocks 2! as shown in Figures 1- and 3. The arms are so shaped that this conveyor frame can beswung upwardly and then inwardly and: downwardly to rest upon the upper portion of the main frame F so that-this conveyor frameF' will be out of the way when not in: use: and. when the tractor is traveling on a roador thelike,

A vertically arranged shaft 23 is. supported for rotary movement in the rear partof the tractor and has a hand wheel 2'4 at its upper end and a Worm 25 is connected to its lower end. An arm 26 has a segmental worm gear 21 on its front end which is pivot-ed to a supporting bracket 28 on the tractor, this gear meshing with the worm 25. The rear end of the arm 26 is connected by a chain 29 with a yoke '30 extending across the frame Fan appreciable distance from the plow carrying end thereof and by turning the shaft 23 in one direction the arm 26 will be caused to raise the left hand end of the frame F, this frame turning on the shaft 8 and the arm I with

itsuniversal joints

4, 3 and 6 moving upwardly so that the left hand end of the frame with the plow can be raised well above the surface of the ground so that these parts will not contact the ground or other surface.

When the device is in lowered position it will be seen that as the tractor travels along the plow l8 will form a furrow at the left hand side of the tractor and the dirt will be thrown upon the conveyor I4 which carries the dirt upwardly and across the rear of the tractor and then the dirt will drop upon the conveyor 19 which slopes downwardly and outwardly so that the weight of the dirt will cause the belt to travel to deposit the dirt at the outer end of the conveyor l9 upon the soil an appreciable distance from the right hand side of the tractor and thus the field will be terraced easily and quickly. In order to tighten the conveyor belt I4 a roll 3| engages the lower reach of the belt, see Figure 4, and the trunnions of thisroll are located in the bearing blocks 32 which are swivelled to the lower ends of the screw shafts 33 passing through nut members 34 supported in the side members 35 of the frame F. Thus by turning these shafts 33 the roller 3| can be lowered or raised'and thus the tension of the belt l4 can be regulated.

It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.

It is to be understood that changes may be made in the construction and in the combination and arrangement of the several parts provided that such changes fall within the scope of the appended claims.

Having described the invention, what is claimed as new is:
