SPECIFICATION forming part of Letters Patent No. 611,554, dated September 27, 1898.

Application inea December 20,1397. srie No. 662,642. (No model.)

To @ZZ whom it may concern:

Be it known that I, SAMUEL N. BIsTLINE, a citizen of the United States, residing at Andersonburg, in the county of Perry and State of Pennsylvania, have invented new and useful Improvements in Sulky-Cultivators, of

- which the following is a specification.

This invention relates to sulky-cultivators more especially designed for cultivating corn and it has for its object to provide such a cultivator with improved means for shifting the gangs of plows laterally, to provide improved means for raising and lowering the gangs of plows, and for placing a yielding pressure on said gangs.

It also has for its obj ect to provide improved means for adjusting the wheels for side-hill work, and finally it has for its object to improve and simplify the construction and render more efficient the operation generally of this class of machines.

To these ends my invention consists in the features of construction and in the combination and arrangement of parts hereinafter described, and particularly pointed out in the claims following the descriptiomreference being had to the accompanying drawings, forming a part of this specification, wherein- Figure 1 is a side elevation of my improved Y cultivator, one of the wheels being removed. Fig. 2 is a rear elevation thereof. Fig. Sis a top plan view. Fig. 4 is a detail view of the hand-lever for adjusting the wheels, and Fig. 5 is a similar View of one of the spring-arms for placing pressure on the drag-bars.

Referring to the drawings, the numeral 1 indicates the axle, to which are rigidly attached the side beams 2 and the front crossbeam 3, constituting the frame of the machine. To the axle 1 and cross-beam 3 is attached the tongue or pole 4. The opposite ends of the axle are bent downward, as at 5, and are provided with vertically-depending pivot-pins 5, on which are journaled or pivoted the axle-spindles 6, carrying the groundwheels 7. Each of the spindles 6 is provided with an inwardly and upwardly extending armS, that liesunder the-axle 1, and at its inner end has a limited oscillating movement in a stirrup 9, attached to the axle. 'To the adjacent ends of the arms 8 are loosely attached rods 10, which at their other ends are loosely connected to the opposite ends of a lever 11, pivoted at its center to a lixed support 12, carried by the cross-beam 3; To one end of the lever 11 is connected a rod 13, the other end of which is connected to ahand-lever 14, pivoted at its lower end on a stud 15, projecting from the inner side of one of the side beams 2 of the frame of the machine. The hand-lever 14 is adapted to engage a segment-rack 16, attached to the said side beam, to hold the lever to its adj usted position, and in order to cause said vhand-lever to engage the teeth or notches of the rack with certainty and hold it in such engagement I arrange a coiled spring 17 on the endof the stud 15, which bears against the hand-lever and operates to throw it .into engagement with the rack.

From the foregoing description it will be evident that by oscillating the hand-lever 1-1 in one or the other direction the centrallypivoted lever 11 will also be oscillated and v will draw one of the rods 10 in one direction and force the other rod 10 in the opposite direction, thus simultaneously oscillating the arms 8 and spindles 6 in opposite directions and throwing the wheels equally at an angle to the line of draft.

It will of course be understood that the value of the angle to which the wheels will be thrown will depend on the extent to which the hand-lever 14 is thrown and that the direction in which the wheels are turned will depend upon the direction in which the handlever is thrown. By the means described the wheels will be firmly held at any angle to which they may be adjusted, or also rigidly held in alinement with the axle 1. This adj ustment of the wheels is especially advantageous in side-hill work, as the wheels can be turned to the proper angle to prevent the madrag-bar 19 of each plow-gang is pivoted in the bifurcated end of a swivel 22, whereby IOO the gangs may be freely raised and lowered, and each of the swivels 22 is journaled on a vertically-depending stud-shaft 23, rigidly fixed in the forward end of the machineframe. The swivels 22 may be turned freely on their stud-shafts to permit the plow-gangs being swung laterally, and fixed to each of said swivels is an arm 24, which projects inwardly and at its inner end is loosely connected to one end of a rod 25. The other end of said rod is connected to a foot-lever 26, which is centrally pivoted to the under side of the axle. The opposite ends of the footlever 26 terminate in stirrups or footholds 27, which are in convenient reach of the feet of the operator when the latter is in place on the drivers seat 28, carried by the frame of the machine. As shown, the rods 25 are connected to the foot-lever 26 on opposite sides of the fulcrum of the latter, whereby when the foot-lever is oscillated in one direction or the other the arms 24, fixed on the swivels 22, will be oscillated in opposite directions, thus simultaneously throwing the two gangs of plows laterally to the right or left of the line of draft. The operator may thus by means of his feet readily swing the two gangs of plows to the right or left to follow the rows of plants or to avoid obstructions. In order to regulate the degree of adjustment or the lateral throw of the plow-gangs, I make the connection between the rods 25 and arms 24 adjustable by forming in the inner end of each of the arms 24 a plurality of perforations 29, in any of which the hooked ends of the rods 25 may be engaged. It will be obvious that by changing the hooked ends of the rods 25 from one set of perforations to another the throw of the arms 24 will be altered and the lateral swing of the plow-gangs correspondingly regulated. I prefer to arrange the perforations 29 in the end of each arm 24 in two or more parallel rows, the perforations of one row being arranged opposite the spaces between the perforations in the adjacent row or staggeredf7 as shown, such arrangement permitting of a wide latitude of' adjustment of the connection between the said arms and rods.

For raising and lowering the plow-gangs and for placing a yielding pressure on the drag-bars I provide the following mechanism.

Arranged immediately in rear of the axle l is a rock-shaft 30, the opposite ends of which are journaled in the side beams 2. Fixed on the rock-shaft 30 are two arms 3l, to the free ends of which are attached chains or other suitable flexible connections 32, that at their other ends are connected to the plow-gangs, the chains in the present instance being shown connected to the central drag-bars 19 of the plow-gangs. To the rock-shaft 30 is pivoted a hand-lever 33 in such manner that it may oscillate in a plane passing longitudinally through the rock-shaft, but which is incapable of oscillating in a plane transversely to said rock-shaft independently of the latter.

By rocking or turning the rock-shaft in its bearings by means of said hand-lever the arms 31 are oscillated and by means of the chains 32 raise and lower the plow-gangs. Fixed on one end of the side beams 3 is a segment-rack 34, the teeth or notches of which are adapted to be engaged by the hand-lever 33 to lock the latter in its adj usted position, and in order to cause said hand-lever to engage said rack with certainty I provide a coiled spring 35, which is confined between the hand-lever and a support 36, fixed on the rock-shaft, said spring constant-ly exerting its force to throw the hand -lever into engagement with the rack. By the means described the plow-gangs may be readily raised and lowered and may be held at any elevation desired.

Arranged on the forward portion of each of the central drag-bars 19 of the plow-gangs is a yielding pressure device constructed as follows: The numeral 37 indicates an upright arm or bar formed of resilient or spring metal and provided at its lower end with a saddle or yoke 38, which straddles the drag-bar and is pivotally attached thereto by a pin 39, that passes transversely through the drag-bar and through eyes 40, formed in the sides of the saddle or yoke. As shown, the rear end of the yoke or saddle 3S rests upon the top of the drag-bar at a point somewhat remote and in rear of the pivot 39, so that if the arm 37 be drawn backward the saddle or yoke will operate to depress the drag-bars. The upper ends of the spring-arms 37 are connected to the forward ends of rods 4l, the rear ends of which are connected to a rigid arm 42, fixed on the rock-shaft 30. It will be readily understood that when the rock-shaft 30 is turned to lower the plow-gangs the spring-arms 37 will be flexed and drawn backward, thus causing the yokes or saddles 3S to force the drag-bars downward and hold the shovels properly to their work. It will also be evident that the farther'the shovels are lowered the greater will be the pressure exerted by the spring-arms on the drag-bars and that owing to the resiliency of the arms 37 the pressure will be a yielding one to permit the shovels to raise up when they encounter an abnormal resistance. By the means described the pressure placed upon the plow-gangs is automatically regulated, the farther the shovels are lowered to take deeper into the earth the greater the pressure will be upon the drag-bars to hold the shovels down into the soil, while, on the other hand, when the plowgangs are raised to clear the earth the pressure will be entirely taken olf the drag-bars.

From the foregoing description it will be obvious that all the adjustments and operations of the machine may be conveniently and quickly performed by the driver without leaving his seat and that all parts of the machine are at all times thoroughly under his immediate control.

If it be desired to give an increased yieldingpressure to the drag-bars, a coiled spring Iog Igc

611,554 p y r.

43 may be inserted between the rear end of each of the saddles 38 and the top of the drag-bar, as shown in Fig. 5. This will permit of a limited yielding movement of the drag-bars independently of the pressure exerted by the spring-arms 37.
