SULKY-PLOW.

Specification of Letters Patent.

Patented Feb. 27, 1912.

Application filed .April 10, 1911. Serial No. 620,183.

To all whom t may concern Be it known that I, IVILLIAM L. PAUL, of South Bend, in the county of St. Joseph and State of Indiana, have invented certain new and useful Improvements in Sulky- Plows; and I do hereby declare 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 improvements in sulky plows, and more particularly to such as embody in their construction, a crank aXle having a journal mounted in the hub of a land wheel, and a vertically movable standardaXle having a slanting journal mounted in the hub of the slanting furrow wheel.

The object of my present invention is to provide simple and efficient operatingdevices for sulky plows of the class specified, whereby both wheels can be moved simultaneously to raise or lower the plow, with the use of a single lever, and to construct the mechanism that the furrow wheel can be separately adjusted relatively to the land wheel with the use of a lever provided for this specific purpose.

I/Vith this object in view, the invention consists in certain novel features of construction and combinations of parts as hereinafter described and pointed out in the claims.

yIn the accompanying drawings, Figure 1 is a side elevation of a sulky plow embodying my improvements. Fig. 2 is a plan view of the same, and Fig. 3 is a transverse sectional View.

1 represents a plow beam constructed at its rear end with a standard 2 with which the soil engaging member 3 is connected. Brackets 4-5 are secured to the beam and project'laterally therefrom respectively in opposite directions,-said brackets, together with a smaller bracket 6 secured to the bracket l5 and to the beam, constituting a frame for the accommodation of various parts of the plow mechanism. A crank axle 7 is mounted in the brackets 4 and 6 and provided at its outer end with a journal 8 which is mounted in the hub of a land wheel 9.

To the outer end of the bracket 5, a tubular casting 10 (preferably rectangular in cross-section) is secured and serves to guide a vertically disposed standardaxle 11,- the latter hL ving at its lower end a slanting journal 12 mounted in the hub of a slanting furrow wheel 13. The end of the crank aXle 7 which is mounted in the bracket 6 is provided with an arm 14 and the shank 15 of a guide loop 16 is loosely mounted in said arm-,fsaid shank passing transversely through the arm. A bar or rod 17 has sliding movement through the guide loop 16 and is pivotally attached at its upper end to the standard-axle 11 near the upper end of the latter. The rod or bar 17 carries a toothed segment 18 to be engaged by a detent 19 carried by a lever 20. The lever 2O is pivotally attached a comparatively short distance from its lower or forward end, to the rod or bar 17. Beyond its pivotal connection with the rod or bar 17, the lever 20 is bent slightly upward and pivotally connected with the upper end of a pitman is attached to the shank 15 of the guideloop 16.

To the outer end of the bracket 4: (which is adjacent to the land wheel) a toothed segment 22 is secured. A lever 23 is mounted on the crank axle 7 and secured to the crank arm thereof by means of a bar 24V-said lever 23 being provided with a detent 25 to engage the teeth of the segment 22.

With the construction and arrangement of parts above described, it will readily be seen that when the lever 20 is in locked relation to the segment 18 and the lever 23 is operated, the crank-axle will be turned to effect the raising or lowering of the plow. Assuming that the lever 23 has been moved in a direction to cause the raising'of the plow, the crank-axle operating through the medium of the land wheel will raise that side of the structure and simultaneously, motion will be imparted by the arm 14 to the pitman 21 to move the latter ldownwardly and said pitman being connected with the locked lever 2O which in turn is connected through the rod or bar 17 with the standard aXle 10, the latter will be moved downwardly and, through the medium of the furrow wheel 13 resting on the ground, cause thatside of the structure to be raised. Should it be desired to adjust the furrow wheel with relation to the land wheel, this can be 21, the lower end of which latter A accomplished by means of the lever 20. It is apparent that if the lever 2O be moved downwardly from the position shown in F ig. l, theV standard axle l0 will also be moved downwardly and the furrow wheel side of the machine will be raised independently of the land wheel side. Of course, should the lever 2O be moved in the other direction, the standard axle 10 would be raised and result in the lowering of the furrow wheel side of the structure relatively to the land wheel side.

Having fully described my invention what I claim as new and desire to secure by Letters-Patent, is,

l. The combination with the land and furrow wheels of a sulky plow, a crank axle having one of said wheels journaled on its crank arm, and provided at its opposite end with a crank arm, and a lever and sector rack for rotating the crank axle, of a vertically adjustable standard axle having one of said wheels journaled thereon, a guide connected with said crank arm, a sliding bar pivoted at its upper end to the standard axle and its lower end arranged to slide in said guide, a sector rack connected with the` slidmg arm, an operating lever pivoted to the sliding arm, and a pitman pivotally connected at its upper end to the operating lever and at its lower end to said guide, substantially as set forth.

2. In a plow, the combination with a frame and a soil engaging member, of a crank-axle mounted in said frame, a wheel having the journal of said crank axle mounted in its hub, the crank-axle, a vertically movable standard axle provided at its lower end with a journal, a furrow wheel in which said journal is mounted, a rod or bar connected with the standard axle and having sliding connection with the arm at the adjacent end of the crank axle, a lever pivoted to said rod or bar, a segment connected with said rod an arm at the opposite end of or bar and adapted for coperation with said lever, apitman connected with said lever and with the arm at the adjacent end of the crank axle7 a lever secured to the crank axle, and a toothed segment secured to the frame for cooperation with a detent carried by said last mentioned lever.

In testimony whereof, I have signed this specification in the presence of two subscribing witnesses.

IVILLIAM L. PAUL.
