GANG- AND S'ULKY RIDING-PLOW.

Specification of Letters Patent.

Patented May '7, 1912.

Application filed November 5, 1910. Serial No. 590,912.

To all whom it may concern Be-it known that I, IRVING CLEMENT NEL- SON, of the city of Winnipeg, in the Province of Manitoba, Canada, have invented certain new and useful Improvements in Gang and Sulky Riding-Plows, of which the following is a specification.

My invention relates to improvements in gang and sulky plows, and the objects of my invention are to provide automatic means for leveling and poising the plow without the necessity of operating any levers or the like.

Further objects are to enable the plow to take the ground easier and with less expenditure of force than heretofore; to enable all the operating levers to be placed on one side of the plow; to enable the frame of the plow to be placed nearer the ground, thereby, giving greater strength to the structure, and to enable a lighter frame to be used.

Another object is to provide an instrumentality of the class specified which from an operative standpoint will, in usage, possess a high degree of efliciency and effectiveness and which, structurally considered, will be of the greatest possible simplicity, being composed of but a few parts, all adapted for being made at a minimum cost and individually so formed as to be capable of being readily assembled in compact arrangement for accomplishing the purpose intended.

Other objects and advantages will be in part obvious and in part pointed out hereinafter.

With these and other ends in view, this invention accordingly consists in the features of construction, combination of parts and arrangement of elements hereinafter more explicitly set forth as an exemplification of the underlying principles involved in the invention.

In order that this invention may be more fully understood and be comprehensible to others skilled in the art, drawings illustrating a convenient means of carrying out the same are pointed out as part of this specification, and while the controlling principles of the invention may be otherwise applied by modifications falling within the scope of the claims, the hereinafter disclosed embodiment is that which will ordinarily be preferable to employ in practice and is regarded as representing substantial medium of the side crank on the axle.

improvements over the many obvious or implied variations of the same. In such drawings, it is to be noted that like numerals refer to corresponding parts throughout all the figures in the drawings, in which;

Figure 1 is a side view of a gang plow embodying the present invention. Fig. 2 is a perspective view showing the main or land ax e.

The majority of the parts of the plow herein illustrated, such as the seat, rear axle, front axle, hitch, plow beam and share, and rear andfront furrow wheels will be of any usual construction at present known in the art. The frame A is also of usual form, but may if desired, bemade lighter than ordinary. In accordance with the present invention, a main land wheel axle B is provided extending transversely across the frame and journaled in bearings on the sides thereof, this axle being provided on one side with a side crank 10 supporting the land wheel C, and with a central crank 11, the purpose of which will be hereinafter explained.

The land wheel 0 is directly mounted on the crank 10 of the axle B, and the bracket usually employed to support the land wheel is eliminated, the forward motion of the land wheel being accomplished through the The plow beams D are pivo-tally supported at their forward end in the usual manner, their rear ends being adapted to be raised and lowered by suitable means, such as the foot lever F.

The central crank 11 on the axle is in the form of U shaped bend, and performs two functions. The first of these is the leveling of the plow through movement of the land wheel. When one of the plow beams D is raised through usual mechanism, it is adapted prior to reaching its uppermost position to engage the lowermost portion 12 of the crank 11 and thus swing the land wheel forward as desired, and thereby level the plow. In addition to this, it'will be noted that the U-shaped bend forming the crank 11 will permit the plow beam to move upwardly a greater distance past the frame, the upward clearance of the plow being thus increased, it will be possible to place the frame closer to the ground. The land wheel is also adapted to be operated by hand through the medium of a lever E provided on the opposite side of the axle B to that on which the land wheel is mounted, the lever beingprovided with any of the usual latch devices for holding it in adjusted position, in addition to the provision for automatic swinging of this end of the axle when operated. It may be mentioned that in order to provide for the operation of the axle by the plow beam, the lever E is preferably connected to the axle by a suitable ratchet arrangement which will enable the axle to move independently of it on the upward movement of the plow beams. This .is accomplished by mounting the rack segment 13 fixedly and the lever E loosely upon the shaft 11. Therefore it will be seen that when the axle 11 is raised by the plow beam the latch device 14 on lever E will ride over the teeth on segment 18 during this movement. It will of course be understood that the lever is in a convenient position to be grasped by the operator. It is evident that the land wheel axle might if desired, be formed in a plurality of separate parts connected so as to operate together.

As many changes could be made in the above construction, and many apparently -wide1y difierent embodiments of my invention within the scope of the claims constructed without departing from the spirit or scope thereof, it is intended that all matter contained in the accompanying specifications and drawings shall be interpreted as illustrative and not in a limiting sense.

What I claim as my invention is:

1. A plow of the character described having a plow beam, a land wheel, engaging means for throwing said land wheel forwardly, said plow beam being adapted to come into engagement with and to actuate said engaging means during the upward movement of said plow beam to throw said land wheel forwardly.

2. A plow of the character described comprising a frame, a plow beam mounted thereon, a land wheel axle journalcd in the frame, said plow beam being adapted to come into engagement with said axle dur- *ing the upward movement of said beam.

3. A plow of the character described comprising a frame having parallel side members, an axle journaled in the frame formed with a central crank and a side crank, a land wheel mounted on the side crank, and a plow beam or beams adapted in its upward movement to come into engagement with the central crank to throw the land wheel forwardly.

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

IRVING CLEIVIENT NELSON.
