' Application filed February 1, 1904a Serial No. 191.526. (N0 model.)

To ztZZ whom it may concern:

Be it known that I, JEROME E. RUSSELL, a

citizen of the United States, residing at 'Iitonka, in the county of Kossuth and State of Iowa, have invented a new andnseful Improve jects, first, to be able to change the inclination of the plow to the ground in such a manner that the tilting of the point down to make it. run deeper does not involve the raising of the .heel of the plow, and vice versa, but when the point of the plow is tilted down the whole lay of the plow is tilted down about a center in rear of the beam.

A second object is to be able to raise and lower the entire plow without changingthe inclination.

A third object is to provide means for hold ing the plow in the ground or maintaining it in an elevated position.

A fourth object is to render the vertical ,ad j ustment of the front furrow-wheel easy and' free from gripping and binding. 1

A fifth object is to so connect the front and rear furrow-wheels as to render the one ad justable independently of the other.

My invention consists in certain novel constructions and arrangements of parts for securing the above-named objects and for ob taining other desirable results, which will be hereinafter fullydeseribed with reference to the drawings, in which- Figure 1 is a vertical side elevation, partly broken away, showing the plow in' its position .in the ground. Fig. 2 is a similar view showing the plow raised for transportation. Fig; 3 is a top plan view. Fig. 4 is a vertical 1on gitudinal section showing the means for tilting the plow-point. Fig. 5 is a sectional side View, and Fig. 6 a front view, of the means for adjusting vertically the front furrow wheel; and Fig. 7 is a detail in perspective of the plow-supporting device.

In the drawings, A represents an elongated rectangular frame having a laterally-projecting bracket-shaped extension A, (see Fig. 3,)

which parts together form the frame of the the rectangular frame.

sulky-plow. The frame is supported in the usual manner upon three wheels B, (l, and I). The front wheel B runs in the previous furrow, the middle wheel C runs on the high unplowed land, and the rear wheel 1) runs in the furrow just being turned by the plow, and E is the plow, which is suspended beneath the sulky-frame and is made vertically adjustable, so as to be lowered to contact with the ground in plowing or be elevated above the same for transportation. All the wheels are mounted upon crank-axles connected to the framework, and the front and middle wheels are made vertically adjustable to suit the depth'of plowing. As so far described the sulky-plow is of the common and well-known form, and I will now describe my features of improvement. E is the plow-bea1n, which ismade longer than usual. It extends from a position behind the point of the plow rearwardly and upwardly over the moldboard and then forwardly to a position in front of the forward end of the rectangular supporting-frame. At the front end'the beam is provided with flanged and perforated jaws E, forming a elevis attachment, and these jaws are connected by a bolt 0 and links a with a bolt This bolt (2 is carried by the twin arms a of a rocking elbow-lever E, which is journaled in hearings on the front end of the framework. The upper arm of this rocking lever is connected to a horizontal rod E", which runs longitudinally to the rear, and is jointed to a hand-lever F, which I term a tllting-lever, since its function is to tilt the plow to a different inclination to the ground, as hereinafter described.

G is a U-shaped bail which carries the main portion of the weight of the plow by being connected tothe plow atthe middle bend of the bail, while" its two side arms extend forwardly and at their ends are turned outwardly at rightangles and form trunnions g 7, that rockin'reinforoed and elongated bearings g g, (see Fig. 3,) secured to the lower edge of The rear end or loop portion of this bail swings about the front trunnions and raises and lowers the plow. In

making connection between the loop of the g 5 is clamped about the loopof the bail and bail and the plow-beam (seeFig. 7) a boxing I O0 i l the upper portion g of the boxing is formed with rearwardly-projecting and offsetting trunnions g" g*. One of these trunnions rests in and plays along the slot of a curved arm H on one side, (see Fig. 1,) and the other trunnion rests in and plays along the slot of a curved arm I, Figs. 1, 3, 7, on the other side. The arm H when the plow is in action extends forwardly and downwardly, while the arm I extends rearwardly and downwardly.

The lower portion g of the plow-supporting box is mounted upon or formedwith a rearwardly-projecting standard E, which is bolted to the plow-beam behind the moldboard and which carries the trunnions g to a point in rear of the plow. The importance of this will be more fully explained hereinafter.

The curved and slotted arm H, Figs. 3 and 4, is rigid with a hub which is journaled upon to a lug rising from the main frame.

an axial bolt H, carried by the framework. This hub has also rigidly attached to it or formed with it an upwardly-projecting and notched segment H whichis adapted to be adjustably locked to the tilting-lever F by a spring-bolt, and said hubhas also a rigid arm H projecting downwardly and connecting by a rod or bar J with the lower end of the lifting-lever J. This lifting-lever is for the purpose of raising bodily the whole plow and for lowering the same, and for this purpose it is pivoted to a reinforced lug J 2 on the framework and has a spring-bolt adapted to engage with the notches of an arch-bar J 3 for holding the lifting-lever to its adjustment.

The slotted and curved arm I (see Figs. 2 and 3) is formed with a rearwardly-projecting arm I at its upper end and is fulcrumed at a I is a long helical spring, which at one end is hitched to an offset at the end of the arm I, and at the other end the spring is hitched to the front end of the main frame.

The two points of connection with the plow serve to raise the plow bodily by a practically parallel motion, the lifting strain being ap- I plied at the bolt 6 at the extreme front end of the beam and at thetrunnions g in the rear of the plow-beam. vThis lifting power is applied by swinging the lifting-lever J to the rear. This action pulls the connecting-rod J forward, and with it the arm H rocking the hub on axial bolt H and lifting the slotted arm H, which in turn raises the-trunnion g and the plow. As this hub is rocked to the rear the segment Hand engaged lever F are thrown to the rear, pulling back rod E. This rocks the elbow-lever E e and lifts the links 0 and the front end of the plow. As the lever J passes from a vertical to a horizontal position the various parts pass from the position shown in Fig. 1 to that shown in Fig. 2.

In the movement just described the trunnions g ride in the slots of the two arms H and I, moving toward the centers of each arm, which arms cross each other at the axial line of the trunnions, as seen in Fig. 1. .W hen the plow is in its elevated position, as in Fig. 2, thetension of spring I at the attaching-point a of arm I is above the center a of the elbow I I, and consequently the tension of the spring I holds up the curved arm I and helps to lift and sustain the plow in elevated position, making this operation easy. When the plow is in its lowest position at work in the ground, the attaching-point a of the spring I is somewhat below the center a of the elbow I I, as seen in Fig. 1, and consequently the tension of the spring aids in holding the plow down to its work in the ground.

The U-shaped bail G is made with unusually long side arms, and the angle which these arms occupy when the plow is in the ground, as in Fig. 1, is such that the draft strain applied to the front of the plow-beam causes a downward thrust of the plow into the ground and an upward lifting strain on the front of the sulky-frame, making the sulky run easier and causing the plow to do better work.

In sulky-plows it is desirable to be able to tilt the point down at different inclinations to suit different soils. Heretofore this has been done; but in tilting the point down the heel is raised, and this so changes the relation of the rear part of the plow to the furrow being turned as to cause it to turn the furrow improperly and let the plow run out of the ground. To overcome these difficulties, 1- locate the pivotal center about which the plow-point is tilted at a distance in rear of the beam and at the back end of the plow. This point is the center of the trunnions g, which are mounted on the rearwardly-extending standard E whose value will now be explained.

By referring to Fig. i it will be seen that by taking the trunnions g as a center and running a straight line to the point of the plow as a radius of adjustment if the plow-point is lowered about the center all of the plow will be lowered, as indicated in dotted lines, but the point will be lowered more than the heel by reason of its greater distance from the center, and thus the plow will be made to dig deeper into the soil without raising the heel of the plow or falsifying the position of the moldboard, but the latter will scour and turn a perfect furrow in all adjustments. This result is attained by locating the pivotal center g, about which the plow is adjusted, in rear of the plow-beam and at practically the rear end of the moldboard. This explains the value of the rearwardly-oifsetting standard E.

I will now explain the mechanism for giving the tilting adjustment to the point of the plow. When the plow is lifted bodily without changing its inclination, it is lifted by the trunnions g and also by the bolt 6 at the front end of the beam, as heretofore explained, both these points moving upwardly at the same time.

i which sustain the front end of the plow-beam.

This causes the angle of the plow to the horizontal to be changed, so as to run deeper, and as this movement is made about the trunnion g as a stationary center in rear of the plowbeam and moldboard it will be seen that the entire plow moves down slightlythat is to say, the heel of the plow is not thrown up by a depression of the point, which avoids the ob ections heretofore referred to. This tilting down of the plow-po1nt is very necessary to hold the plow into certain kinds of stiff or mucky soils.

The front furrow-wheel B is journaled on the bent arm at the lower end of the vertical spindle-rod B. The upper end of this rod is attached to the upper end of a helical spring B which at its lower end is hooked into a hanger-bar A depending from the main frame A. By means of this spring the front end of the sulky is supported in an elastic manner upon the front furrow-wheel, so that the vertical adjustment of the front furrow-wheel may be easily accomplished, since the spring aids the adjusting devices. These adjusting devices consist of a long lever K, Figs. 1, 5, and 6, fulcrumed upon a fixed bolt K in a vertical box K attached firmly to the framework A. A hooked arm K connects the lever K with a vertical slotted bar K*, which at its lower end is bent in and perforated and embraces the lower end of the spindle between two collars 7 7:. The upper portion of the bar is guided by its slot, which embraces thepivotbolt K. A locking spring-bolt K on the lever .K (see Fig. 3) engages a notched segment K on the vertical box K to hold the lever .to its different adjustments.

wheel, the vertical spindle slides through the boxing K and is guided against cramping by the slotted bar K and the movement is rendered easy by the balancing effect of the spring B.

The rear furrow-wheel D is carried upon the lower bent arm of a vertical spindle l),

turning about a vertical axis in bearings When the lever K is turned to raise or lower the front furrow an adjustable one, as follows, reference being had to Fig. 3: On top of the rear spindle D is a rigid arm D, having a screw-stem d, passing through a slot (5 in a horizontal plate 1), pivoted on the upper end of the spindle .l) and pivoted also to the rear end of a long rod D*, which runs to the front of the main frame. A clamp-n ut on the screw-stem fl adjustably connects the plate D and the arm 1). A similar adjustment atthe front end connects the rod 1)" to the vertical spindle B of the front furrow-wheelthat is tosay, ahorizorr' tal plate B is pivoted on the spindle B and also to the rod D and at an intermediate point is connected to a rigid arm 13' on the spindle by a slot and screw-stem b I). These connections while coupling the frontand rear wheels together for a similar movement when in action also give the desirable result of permitting each furrow-wheel to be adjusted independently of the other. The tongue-plate T is hinged about a horizontal bolt to the plate B and is provided with a transverse slot at its front end :for the adjustment of the tongue.

As both the front and rear furrow-wheels are coupled together :for simultaneous movement about their vertical axes, it will be seen that the rear furrow-wheel arm, being the longer, is less affected by variations in the position of the front furrow-wheel arm and consequently is better ableto resist the side thrust of the plow.
