PLOW.

'Application llled November 4, 1922. Serial No. 599,108.

To all 'whom it may concern: Be it known that I, LEE P. BIGGEns, a citizen of the United States, residing at Palmersville, in the county of Weakley and State of Tennessee, have invented a new and useful Im rovement in Plows, of which the following 1s a specification.

My invention relates to a plow of the rotary type which may also be used as a pulverizer by an interchange of the earthworking elements or tools, or by employing elements or tools of both types, may be used both to plow and harrow simultaneously.

One of the important features of the 1nvention relates to the manner in which the earth-working elements are disposed, whereby the rotation of the same, in add'- tion to working the earth, furnishes either a part or all of the force by which the implement may be propelled over the surface of the ground.

A further object of the invention is .torso Figs. 7 and 8 are detail views of different types of earth-working elements.

eferring now to the details of construction. The invention comprises a rectangular frame having front and rear members l and 2, respectively, connected by side members 3 and 4, each of which is provided with a flange 5 at each end secured to the members l andg by bolts 6 or the like. The frame members 1 and 2 are each made hollow and provided along the inner edge with slots 7 and 8, respectively, through which the shafts that carry the earth-working elements exas journal bearings for the shafts 11. Bc-I constructv the implement that the vaious,j;/t\veen these blocks 10 are arranged alterparts thereof may be easily assembled orI disassembled for the purpose of replacing worn or broken parts, or for sharpening the earth-working elements. l

The invention consists further in the ar- 36 rangement of the shafts on which vthe earthworring elements are mounted so that they extend in the direction of the line of draft, and also in the arrangementof thc earthworking elements on the shaft, so that part of them are engaged with the ground while others are in the air, and the elements on either side of the machine are so balanced that there will be little tendency to move sidewise.

The'invention will be better 4understood by the following description, taken in connection with the accompanying drawings, which illustrate one structure by means of which the invention may be carried out.

In the drawings v Fig. lis a plan view of the invention.

Fig. 2 is a horizontal sectional view.

Fig. 3 is a rear elevation.

Fig. 4 is a side elevation.

Fig. 5 is a plan view of a ortion of the invention showing a modifie construction.

Fig. 6 is a detail sectional view showing the means for mounting the plow shafts.

nately the complementary spacing blocks 12, which may also be rovided with bearings 13 for receiving a ditional shafts, or in order to provide further latitude in the relatiffrfe arrangements of the shafts. The blocks 0 and 12 are secured at the ends of the members 1 and 2 by end blocks-14, which may be adjusted by means of screws 15` or the like.

The shafts 11 are preferably provided at their forward ends with ball races 16 which take up the forward thrust exerted by the earth-working elements 17 or 18 carried by the shafts.

It will be noted that the earth-working elements are disposed in planes which are inclined to the direction of the shafts on which they are mounted, -so that as the elements engage the ground, the will exert a forward thrust against the rame of the implement after the manner of a ship propeller. The elements 17 have the same function as ordinary disk plows, but, as shown, are preferably made in the shape of sectors and so disposed in relation to the circumference of the shafts that certain of the disks engage the ground while others are in the air, thus distributing the load so as to obtain a Continous and substantially uniform action and thereby make it possible to operate the low with less power than would otherwise be necessary.

In order that the disks 17 may be removed I with the least possible trouble, when it is necessary for t em to be sharpened, each disk is preferably provided with a slotted hub, as shown at 19, whereby -the same may be applied to the shaft and secured thereon by means of clamping members 2O and 21,

l5 of the members 2O and 21 are to the axis of the shaft 1l, in order to fur- `nish the pro elling force. In actual practice, the pre erred angle has been found to 20 be about 12 degrees from a perpendicular,

but this may be varied accordin to the s eed of revolution and the widti of eut esired. The ulverizing elements 18 are formed each with a hub 24 ada ted to re- 25 ceive the shaft, and a cap 25 whic i is secured thereto by means o f bolts 2G.

The' shafts 11 may be driven in any suitable manner. In Figs. 1 to 4, I have shown each shaft provided with a sprocket wheel 80 27, which is connected, by a s rocket chain 28, to the drive shaft 29, that is mounted in bearin s at the upper ends of the standards an 31, rising from the main frame of the machine and from the motor support 32,

Il respectively. The shaft 29 is driven through bevel caring 33 or the like from the motor 34 which, as will be understood, may be profvided with the usual clutch and gear shi t.

In Fig. 5, I have shown a modified driving gear in which the shafts 11 are extended, as at 35, through the slot 9 at the forward side of the frame member l, and provided at their forward ends with a bevel ear connection 36 with a eountershaft 37 ournaled in bearings 38 at the forward si e of the frame. This countershaft 37 may be provided with a sprocket wheel 39, that may be connected with the motor shaft, by the usual sprocket chain.

The frame of the machine is sup orted at the rear, the proper distance a ove the ground, by means of wheels 40, each of which is carried by a fork member 41, the

latter being adjustably connected by means of corrugations or teeth 42 with an upstanding bracket 43, secured to the side of the frame. The members 41 and 43 are secured in their adjusted relation by means of a bolt 44 which extends through the member 41 and through a slot 45 in the bracket 43.

The front or steering wheel 46 is secured at the lower end of a fork member 47, which is rotatably mounted in a bearing 48, and held against longitudinal movement by a collar 49. The fork member 47 is provided at its upper end with a tiller arm 50. The bearing member 48 is formed in a bracket 52, adjustably connected with a standard 51, in a manner similar to the rear wheel forks.

It is understood that the plow disks 17 will be set at such an inclination to the shafts 11 that, ordinarily, the machine will be propelled over the ground by the forward thrust exerted by the disks upon rotation, and that the disks will, at the same time, plow the earth. In order, however, to use the machine under all conditions and in all kinds of ground, it may, in some instances,

be necessary to employ one or more draft animals or a tractor to supplement the proelling force ofthe lows. In such cases, iowever, only a smal additional force will need to be exerted by the draft animals.

As illustrated in Figs. 1 and 2, each of the shafts l1 may be provided with both a plow disk 17 and a pulverizing tooth 18, so that one trip across the ground will both plow and harrow it.

The essential features of the invention may also, with slight modifications in the frame, be used in road grading. It will also. be observed that an implement constructed according to my invention may be completely disassembled in the least possible time by removing the screws l5 and bolts 6 at one side of the frame.

While I have shown and described the specific construction of those forms of my invention which are at present preferred, it will be observed that various modifications may be made therein within the scope of what is claimed without departing from the spirit of the invention.

What is claimed is 1. In a wheeled low, a plurality of parallel shafts disposed? substantially 1n the line of travel, sector-shaped disk lows ri idly mounted on the shafts in planes ob ique to the axes of the res ective shafts, a pulverizing tooth on eac to the direction of the shaft, and a motor to which the shafts are geared to rotate in unison, said shafts being so disposed that certain of the disk sectors on each side of the implement will engage the round simultaneously while others on eac side are above the ground, whereby the load is distributed so as to obtain a continuous and substantially uniform action.

2.
