CHARLES V. BERGER, OF RAVENNA, TEXAS.

PLOWING-MAGHINE.

Specification of Letters Patent.

Patented Dec. 31, 1918.

Application filed March 31, 1917. Serial No. 158,931.

To all whom it may concern:

Be it'known that 1, CHARLES V. BERGER, a citizen of the United States, residing at Ravenna, in the county of Fannin and State of Texas, have invented certain new and useful Improvements in Plowing Machines, of which the following is a specification.

This invention relates to an improvement in plowing machines and more particularly to a machine of this character of the subsoiler type adapted to break up or loosen the subsoil and surface soil.

An object of my invention is to provide a machine of the character described which is so constructed that it will not only loosen up the top and subsoil, but will break up hard pan, will so work the top soil that sprouts, stalks, vines, or the like will be mangled and will be carried beneath the surface to there rot, and build up the land, and which will open and loosen up the ground to such a depth that plants or crops rowing thereon will not be easily affected y droughts as the soil will hold moisture for a great period of time. 0

Another object resides in so constructing the parts that the depth to which the knives or spades cut into and work the earth can be regulated, as can also-the angle of disposition of said blades or spades.

Yet another object is to provide means to be manually setto support the entire structure upon wheels so that the machine can be transferred from oneplace to another'and even along highways, or can be more readily turned and manipulated in the field.

- With the above and other objects in view which will be in part described and in part understood from the specification; drawings, and claims, my invention consists in certain novel features of construction and combination of parts which will be hereinafter more fully set forth.

'In the drawings: I,

'. Figure 1 is a top plan view showing the device of my invention with parts broken away to more clearly disclose the operating Parts; Fig. 2 is a view'in end elevation of the structure shown in Fig. 1; y I v Fig. 3 is a detail sectional view to better illustrate the manner of setting and attaching theblades or spades in the position for use; and, 1

Fig. 1 is a perspective view showing in detail the construction of one of the blades or spades.

The frame 1 which may be built up of tubing, channel-iron members or other suitable material, is constructed to be substan tially rectangular and the bearings 2 and 8 carried at opposite sides of the frame structure 1 have a shaft 4 journaled therein,

which shaft in its body portion is preferably made square or of polygonal shape in cross section for a purpose which will be hereinafter fully set forth. The frame structure might be embodied as a part of a tractor drawn unit or might be provided with a tongue 5 for hitching of draft animals, and in either adaptation it is perhaps preferable that the seat 6 be provided on the frame for the operator.

The arms 7 and 8 are mounted on the ends of the shaft 4 to be capable of swinging movement and at their free ends have bearings provided in which stub- shafts 9 and 10 are mounted. Carrying wheels 11 and 12 are mounted on the shafts 9 and 10, and thus as the arms 7 and 8 are swung to certain predetermined positions the wheels 11 and 12 will support the weight of the frame structure 1 and parts associated there with. Hand levers 13 and 1 1 are mounted on the frame portion 1 and links 15 and 16 connect these levers 13 and 1 1 to the arms 7 and 8, at or adjacent to the lower ends The segmental racks 17 and 18 are provided adjacent the levers 13 and 14, and thus as these levers may be shifted to swing the arms 7 and 8 and thus move the wheels 11. and 12, the setting of the wheels can be fixed at any point through engagement of suitable latch means carried by the levers 13 and 14: with these racks 17 and 18. In the present disclosure the levers 13 and 14 are shown as mounted at the side of the frame structure, however, it will be understood that while access may be had readily to these levers by the operator, the structure might be slightly varied in a manner which is old in the art and which consequently is not here illustrated so that both of the links 15 and 16 would be shifted from a single lever and this lever might be mounted adjacent the seat 6 so that the operator would have access thereto without moving the seat.

As has been stated, the shaft 4 is made of polygonal form in cross section in its body portion and pairs of disks l9 and 20 are provided with central openings of substantially the same form so that the disks may be fitted on the shaft to turn therewith. End disks 21 are provided with outstanding flanges and the bars 22 are mounted and secured upon the flanges of the disks 21 so that they extend substantially parallel with the shaft t and are equally spaced around the peripheries of the disks, thus forming a substantially cylindrical frame structure. The cylindrical frame structure thus provided can be made of a size to fit the particular use to which the device is to be put and it will of course be appreciated that the number of bars 22 will depend in a great measure upon the circumference of the. disks 19, 20 and 21, however, the arms '7 and 8 must in all instances be of sufficient length that when the wheels 11 and 12 are brought to bearing against or upon the ground, the frame will be lifted sufficiently not only to give scant clearance to the cylindrical frame structure, but rather to give a clearance space between the ground and the frame 'structure to allow for projection of tlie knives or spades mounted upon the frame structure in a manner to be hereinafter more fully set forth.

The knives or spades 23, which in the present instance are disclosed as being of substantially the form of the teeth usually applied in the construction of drag harrows, might be of any desired form, and it will of course be appreciated that under varying conditions different types of spades will accomplish more efiicient operation. It is the intention that the spades be secured in conjunction with the disks 19 and 20 and with the end disks 21, so that they will pro ject radially or substantially radially from the cylindrical frame structure between the bars 22 thereof and will at the same time be held against lateral shifting movement To provide for various adjustments as to the length of extension of the spades 23, the disks have the concentrically arranged rows of openings 2 f formed therethrough, the relative positioning of the openings of the Various rows being such that radial rows of openings are provided substantially midway between the mounting of the bars 22, these radial rows however being located well within the body of the disks. The spades 23 are bored through at their inner endsas shown at 25, and those ends which are in tended to be disposed to extend outwardly are made pointed as indicated at 26 or otherwise formed to accomplish the desired action in the use of the machine. Bolts 27 are provided to be fitted through certain ofthe openings 24 and through the openings 25 of the spades 23 and thus the spades will be mounted to have predetermined extension beyond the outer line of the substantially cylindrical frame structure, while at the same time they will be mounted in radial disposition, as is better shown inFig. 2. If desired, the disks might be provided with portions of a rosette clamp around the openings formed therein and the spades 23 might have similar formation as shown at 28, around the openings 25 thereof, this formation being such that the spades would be rigidly held against swinging movement around the bolts 27, the pairing of the disks acting to support the spades against lateral shifting or against movement in line with the axle around which the frame structure is built up. By adjusting the bolts 27 to all be set in a single row of openings 24 as formed around the shaft 4, all of the spades will have the same length of extension from the cylindrical frame and in consequence as the machine is moved forwardly with wheels 11 and 12 raised, the weight will cause the spades 23 to be sunk into the ground over which the machine is traveling until the bars 22 contact therewith, thus the ground will be worked over and renovated without bringing the subsoil to the surface unless it be desired that thisaction be accomplished in which case the angle of setting of the spades can be varied. If desired, a shield or cover portion 29 might be constructed on the frame structure 1 over the part thereof occupied by the cylindrical frame structure and the spades carried thereby, and thus the operator will be protected against injury from coming in contact with the spade.

It will be apparent that when the levers 13 and 14 are shifted to bring the arms 7 and 8 to occupy a substantially vertical position, the wheels 11 and 12 will bear upon the ground and in consequence the frame structure l and the parts associated therewith will be raised to such a height that the spades 23 do not contact with the ground or surface over which the machine is being moved, and in this relation of the parts the machine can be freely turned or maneuvered and can be moved over roads without in any way destroying or affecting the surface thereof.

From the foregoing it will be seen that I have provided a vplowing machine of the subsoiler type which is so constructed that more efficient operation upon practically any charact-er or condition of soil can be accomplished through various settings of the spades and the fitting of various forms of spades, that the spades can be fitted to act upon thesoil in various manners, that the machine can be freely turned or maneuvered in the field and can be moved over roads without injuring the surface thereof by swinging the carrying Wheels into the operative position, and that a number of advantages other than those herein specifically pointed out are accomplished in the use of the structure as set forth.

While in the foregoing I have shown and described only specific construction and specific manners of forming and connecting the several parts, it will be apparent that changes might be resorted to in the constru 0- tion of the frame portion, and that various other modifications might be embodied without departing from the spirit and scope of my invention, and hence I do not wish to be limited to the exact such points which may claims.

The two end disks 21 are arranged so as to have their flange portions extend in opposite directions, and one of the disks 21 on the right hand side of the frame carrying a plurality of spades and the other disk on the left hand side of the frame merely constituting a closure for the frame and arranged in such a manner as to cause the flange thereof to extend in an opposite direction to the flange carried by the disk 21 on the right hand side of the frame. It will therefore be seen that the disk 21 on the left hand side of the frame will not carry any spades as shown in Fig.1.. Fig. 3 however, shows the right hand disk 21 as supporting the spades 23.

I claim 1. A plowing machine including a substantially cylindrical frame portion made up of a plurality of disks. a plurality of spades arranged between adjacent disks, and means passing through the spades and the disks to lock the spades to be held in radial and other than radial extension beyond the peripheral edges of the disks.

2. A plowing machine includinga frame structure having a shaft mounted transversely thereacross, a substantially cylindrical frame portion built up around the shaft and formed of a plurality of disks, a plurality of spades placed between the disks and extending therefrom, and bolts mounted through said spades and through the disks to secure the spades in radial and other than radial extension beyond the peripheries thereof.

3. A plowing machine embracing a frame structure, a shaft mounted transversely across said frame structure and in a horizontal plane, disks having peripheral flanges mounted on said shaft, spades arranged between the adjacent disks with their outer ends extending beyond the peripheral edges thereof, said spades having openings through the inner ends, said disks having openings therethrough, and bolts passed through the be set forth in the Copies of this patent may be obtained for disclosure but only to five cents each, by addressing the eshington, B. Q.

openings of the spades and of the disks to secure said spades in radial and other than radial extension beyond the peripheral edges of the disks.

4. A plowing machine including a frame structure, a shaft mounted on said frame structure, a plurality of disks mounted on said shaft in spaced relation and provided with openings formed in concentrically arranged series around the shaft, a plurality of spades shaped to be received between the disks, and means fitted in conjunction with the spades to be received through the openings of the disks and to clamp down thereagainst to secure the spades in place and lock the same in radial and other than radial extension from the disks.
