Specification of Letters Patent.

Patented April 2, 1907.

To all whom it may concern:

Be it known that I, WALTER P. HENnoN, a citizen of the United States, residing at Dallas, in the county of Dallas and State of T eXas, have invented certain new and useful Improvements in Plows, of which the following is a specification The object of this invention is to support a disk of a disk plow in a manner to permit it to pass over obstructions too hard to be cut. The further object of this invention is to support the plow by wheels, which stand in a vertical position, each wheel having a V- shaped outer edge and one of the faces of the edge standing in a vertical position.

In the accompanying drawings, Figure 1 is a plan view of a plow containing my improvements. Fig. 2 is'an elevation of one of the disk-supports, showing the disk in working position. the disk is elevated. Fig. 4 is a vertical section through one of the supporting-wheels and its support.

i The main frame 1 of the plow is sup )Oltd by the land-wheel 2, front furrow-w leel 3, and rear furrow-wheel 4. The supports for all of the wheels being the same, a description of one will answer. From the main frame extends a sleeve 5, through which passes the vertical support 6 of the wheel. The lifting-lever 7 has the usual connection with the support and sleeve. The support has its lower end 8 turned at right angles to the main portion.

The wheel 3 has its periphery of V shape, one of the faces 9 standing in a vertical position and facing the main frame, as shown at Fig. 1. By thus forming a wheel the vertical face of the periphery will stand against a vertical face of the furrow, thereby preventing the plow from passing to the land. Another reason for thus constructing the wheels is to permit the wheel to rotate on a horizontal support, which permits the employment of a low main frame.

The main frame supports a series of plow ing-disks 21, and as they are all of the same Fig. 3 is a similar view in which construction a description of one will a11- swer.

To the main frame is secured a bracket 10, having two arms 11 and 12. A disk-support 18 is located between these arms and is pivoted thereto by the'bolt 14. From the bracket extends an overhanging arm 15.

Two links 16 are pivotally connected, one link pivoted to the underside of the overhanging arm 15, and the other link has a pivotal connection with the disk-support 13. A bolt 17 passes through the bracket and is located between the link 16.

A spring 18 surrounds the bolt 17 and has one end resting against the nut 19 on the screw-threaded section of the bolt.

and against which the other end of the spring rests. Arms 22 pivotally connect the collar 20 with the link 16. The action of the spring is to hold the disk 21 down in working posi tion; but should the disk strike a hard substance the spring will permit it to rise and pass over. By means of a nut 19 the tension of the spring can be varied.

I claim as in y invention 1. I11 a plow, the combination of a main frame, wheels supporting the main frame, a disk-support having a pivotal connection with the main frame on a horizontal pivot thereby permitting the support to have a ver tical swinging movement, a toggle-lever connection between the support and main frame, and a spring exerting its force on the togglelever thereby holding the disk down to its work in a yielding manner.

2. In a plow, the combination of a main frame, and dish-shaped wheels supporting the main frame and arranged in a vertical position and having one face standing in a vertical plane, the concave faces of all the wheels facing in the same direction.


A collar 20 has a slidable engagement with the bolt
