WILLIAM L. MORFORD, OF MAITLAND, MISSOURI.

PLOW.

To all whom it may concern:

Be it known that I, WILLIAM L. Monroiu), a citizen of the United States, residing at Maitland, in the county of Holt and State of Missouri, have invented a new and useful Plow, of which the following is a specification.

This invention relates to plows and is more particularly an improvement upon the structure disclosed in Patent No. 956,132, issued to me on April 26, 1910, one of the objects of the invention being to provide a machine of this type the shovels of which are separately shiftable so as to adapt the machine for use on hillsides, additional means being employed whereby both of the shovels can be simultaneously raised or lowered.

Another object is to provide a machine of this character which can be quickly adjusted so as to form the furrows at any desired distances apart.

With the foregoing and other objects in View which will appear as the description proceeds the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

In the accompanying drawings, the preferred form of the invention has been shown.

In said drawings :-Figure 1 is a side elevation of the machine. Fig. 2 is a plan view of a portion thereof. Fig. 3 is a detail view of the shovel lifting shafts separated.

Referring to the figures by characters of reference 1 designates the lower or main frame of the machine, the same being preferably substantially rectangular and having front and side strips 2 and 3 respectively supported thereabove by means of standards 4, the rear ends of the side strips being bent downwardly and attached to the rear portions of the sides of the main frame 1. Cross strips 5 connect the rear portions of the side strips 3 and an axle 6 extends transversely of the frame and is secured to the middle portions of said side strips and then extends downwardly to and under the frame 1 from which said axle projects laterally into engagement with the supporting wheels 7 Standards 14 of furrow openers 15, are arranged at the back ends of beams 15. Said beams extend forwardly within the frame 1 Specification of Letters Patent.

and are connected, at their front ends to castings 16, there being a brace 17 diverging forwardly from each beam 15 and connected to a casting 18. The castings 16 and 18 connected to each furrow opener are mounted upon a shaft 19 ournaled in brackets 20 extending rearwardly from the front of the frame 1, said shaft being held against longitudinal displacement by nuts 21 or the like on the ends thereof and the castings 16' and 18 being held against movement longitunally of the shaft by means of set screws 22 or similar holding devices. The distance between the brackets 20 is greater than the distance between the castings 16 and 18 and it will be apparent, therefore, that by loosening the set screws 22, said castings can be shifted along the shaft 19 so as to bring the furrow opener at a desired distance from the center of the machine after which the parts can be tightened. One shaft 19 is provided in front of each of the furrow openers, these shafts being separately revoluble.

A rock shaft 23 is journaled in bearings 24 which are fastened to the axle 6 and one of the strips 5, this shaft being provided at one end with a crank arm 25 and at its other end with a toothed segment 26. A lever 27 extends upwardly from the shaft 23 near the crank arm 25 and carries a pawl 28 adapted to engage a toothed segment which is fixedly connected to one of the strips 24. It is to be understood that lever 27 and segment 26 rotate with the shaft 23. Another shaft 30 alines with the shaft 23 and has a crank arm 31 at one end while a lever 32 extends from its other end, said lever carrying a pawl 33 adapted to engage the toothed segment 26. The two crank arms 25 and 31 have lifting rods 34 extending downwardly therefrom and loosely engaging the beams 15 thereunder, there being a spring 35 upon each rod and which bears downwardly on the beam and upwardly against the crank arm.

Braces 36 may be arranged at any desired points within the frame of the machine and the driving seat 37 is preferably supported from the rear strip 5 at a point where the occupant can easily see all parts of the machine.

The draft tongue 44 is connected to the middle portion of the frame 1 at the front thereof.

As hereinbefore pointed out, by loosening the castings 16 and 18 on shafts 19, the

beams 15 can be adjusted toward or away from each other and afterward secured against movement by the set screws 22. Shafts 19, however, are at all times free to rotate and it will be obvious therefore, that the furrow openers are free to swing upwardly or downwardly. When pawl 33 is in engagement with segment 26, the two shafts 23 and can be simultaneously rotated by means of lever 32, thus causing the arms 25 and 31 to pull upwardly on the rods 34; and elevate the furrow openers. Movement of the lever 32 in the opposite direction will result in the lowering of the furrow openers. By disengaging the pawl 33 from segment 26 and then shifting shaft 23 by means of lever 27, one of the furrow openers can be kept in one position while the furrow opener connected to the. arm 25 can be raised or lowered.

It will be noted, by referring particularly to Fig. 3, that the levers 27 and 32 are normally parallel, said levers occupying these relative positions when the furrow openers 15 are equidistant from the frame 1. Should one of the levers be disposed at an angle relative to the other lever it will be at once apparent that the furrow openers are at different depths and the amount of difference can be easily seen by comparing the positions of the levers. Inasmuch as a person seated above the shovels cannot definitely determine the relativeelevations of the shovels merely by looking down at them, it will be seen that this arrangement of the levers whereby the relative positions can be determined is of considerable importance.

What is claimed is A plow including a wheel supported frame, beams pivotally connected to the front portion of the frame, spaced alining shafts extending transversely of and journaled on the frame, a crank arm extending from the outerend of each of said shafts, linkconnections bet-ween said crank arms and the respective beams, a toothed segment straddling the outer end portion of one ofthe shafts, a lever secured to said shaft, means carried thereby for engaging said segment, a toothed segment secured tothe inner end of said shaft, a lever secured to the inner end of the other shaft, means thereon for engaging the toothed segment on the first named shaft, said levers cooperating to indicate the relative positions of the crank arms and the beams connected thereto, the said crank arms being normally parallel and the levers being also normally parallel.

In testimony that I claim the foregoing as my own, I have hereto affiXed my signature in the presence of two witnesses.
