GENTON P. HOLDEN, 0F JACKSON COUNTY, MINNESOTA.

COLTER.

Application filed November 2, 1916.

To all whom it may concern:

Be it known that I, GENTON P. HOLDEN, a citizen of the United States, residing in the county of Jackson and State of Minnesota, have invented certain new and useful Improvements in Colters; and I dodeclare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to new and useful improvements in colters and the primary object of the invention is to provide a plow with a colter wheel bearing adapted to exclude sand, dust, and other matter and to provide an easy revoluble bearing having an ample oil lubricating capacity.

Another object of the invention is to provide a device of this character which is simple and durable in construction, inexpensive to manufacture, and one which will be very eflicient in operation.

With these and numerous other objects in view, my invention consists of the novel features of construction, combination and arrangement of parts which will be hereinafter referred to and more particularly pointed out in the specification and claims.

In the accompanying drawings Figure 1 is a central vertical section taken through the colter;

Fig. 2 is a vertical section on the line 2-2 of Fig. 1; and

Fig. 3 is a partial side elevation of the colter showing the manner of attaching the fork to one of the boxes.

In describing the invention I shall refer to the drawing in which similar reference characters designate corresponding parts throughout the several views and in which the numeral 1 represents the colter wheel, which is of the usual variety.

The wheel 1 is provided with bearing plates 2 secured to opposite sides of the same by bolts 3. These bearing plates 2 are provided adjacent their inner ends with projecting hort stub axles 4 which are disposed in axial alinement with an opening 5 through the center of the wheel. The plates 2 are furthermore provided with inclined flanges 6 on their periphery which extend outwardly and upwardly, and diverge from the opposite sides of the wheel 1. These flanges 6 form an annular channel on each side of the wheel to receive the dirt, sand, etc., dropping from the colter and preventing the Specification of Letters Patent.

same from working down between the movable and immovable parts of the colter. The colter is also provided with bearing boxes 7 disposed on opposite sides of the wheel in which the adjacent portions of the outer ends of the axles 4 are adapted to rotate. These boxes 7 extend beyond the outer ends of the axles 4 and have axial openings of reduced diameter designated by the numeral 8 and are disposed in alinement with the openings through the axles. The ends of the boxes are positioned adjacent or beyond the ends of the axles so that a space will be left between these two parts to prevent bearing on the ends, and to place the bearing surface directly on-said boxes.

The bearing boxes '7 are provided with outwardly inclined flanges 9 formed integrally with their inner ends, and said flanges terminate below the juncture of the plate flanges and plates and are disposed at approximately right angles to the plate flanges, thus forming an'annular internal chamber on an opposite side of said wheel between the plates 2 and bearing boxes 7. Arranged inside of said internal chambers are the heads and nuts of bolts 3, thus it will be Seen that the inclined flanges form a protective covering or chamber and prevent any dirt, dust, etc., from entering the bearing boxes.

The different parts-of the colter are secured together by a tie bolt 10 having a head 11 at one end and locking nut 12 at the other, which is positioned through the ends of the boxes, the axles, and the central opening in the wheel. The stationary bearing boxes 7 have their outer ends notched as shown at 15 so as to receive the ends of the colter forks. These forks have openings through their ends adapted to receive the tie bolt 10, and when positioned as shown in Fig. 1 of the drawings, the bolt will project through the openings in the forks adjacent its ends, the head 11 of the bolt resting against one fork, while the locking nut 12 rests against the other.

The stationary boxes 7 are provided with openings 13 in which are adapted to be positioned oil cups 14. By this means the hearing surface between the boxes and the axles may always be kept well lubricated to prevent any undue wear upon the same.

Attention is particularly directed to the position of the stationary flanges on the inner end of the boxes, with respect to the flanges on the plates which rotate with the wheel. These different flanges are positioned substantially at rightangles 'to each other, the plate flanges diverging outwardly in one direction from the colter wheel, while the flanges on the stationary boxes terminate below the jointure of the plate flanges and plates,and at a point beneath the extremity of the plate flanges. By this positioning, there will be no possibility of dirt, sand, etc., entering between the bearing of the colter and from working between the movable and immovable parts of the same. These protective flanges will also prevent weeds, etc., from being drawn into the bearings when the plow is being used on wet ground.

From the foregoing description of the construction and operation of this colter, the manner of applying the same to use and the operation thereof will be readily noted and it will be seen that I have provided a simple and efficient means for carrying out the objects of the invention. 7

I claim:

1. In a colter, a wheel, plates securecl to the opposite sides thereof, said plates being formed with inclined flanges on the periphery thereof, said flanges extending outwardly and diverging from the opposite sides of said Wheel, said flanges and sides of Copies of this patent'may be obtained for the wheel forming an annular channel on each side of said wheel, bearing boxes on opposite sides of said wheel and plates, and connected thereto.

2. In a colter, a wheel, plates secured to the sides of said wheel, said wheel and plates having a series of alining apertures ar ranged adjacent their central portion, a plurality of bolts passing through said apertures and securely holding said plates and wheel together, said plate provided with inclined flanges on its periphery, said flanges and sides of said wheel forming an annular channel, bearing boxes on opposite sides of said wheel and plates, said boxes being provided with outwardly extending inclined flanges, said flanges closely engaging the outer faces of said plates and forming a protective chamber, said bolts arranged in said chamber thereby being protectedand said bearing boxes also being provided with a rectangular recess at the outer ends thereof for the reception of ends of the colter fork.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
