SPECIFICATION forming part of Letters Patent No. 432,031, dated July 15, 1890.

Application filed January 25, 1890. Serial No.338,082. A(No model.)

To all whom, it may concern,.-

Be it known that I, DANIEL D. FUNK, a citizen of the United States, residing at Springield, in the county of Clark and State of Ohio, have invented certain new and useful Improvements in Cultivators, of which the following1 is a specification,reference being had therein to the accompanying drawings.

This invention relates to certain improvements in cultivators; and the improvements have reference to constructing the arched axle in two parts, so arranged that they can be adj usted to and from each other to widen or narrow the distance between the plow-gangs carried by each section; have reference to an improved arrangement of draft-rods, wherebyl the draft-strains maybe properly distributed irrespective of the distance between the plowgangs; have reference to an improved spring equipment arranged to sustain a part of the weight of the gangs, to assist in elevating them to a hang-up position, and to assist in depressing them into the ground; and the improvements have reference to certain details of construction hereinafter Inore fully described.

In the accompanying drawings, forming a part of this specification, and in which like reference-lettersindicatecorrespondingparts, Figure 1 represents a side elevatiorrof a cultivator embodying my improvements; Fig. 2, a plan view thereof; Fig. 3, a side elevation, on an enlarged scale, of one section of the arch, the spring equipment, several draftrods, and the adjunct devices, with the beam in operative position; Fig. 4, a front elevation of the same parts; Fig. 5, a detail plan view of a part of the forward coupling of the beam; Fig. 6, a side elevation of the parts shown in Fig. 3, with the beam in elevated r in operative position; Fig. 7, a detail side View of the double arm used in the spring equipment; Figs. 8 and 9, an elevation and a plan view of the cross-head detached; Figs. 10 and 11, detail side views of beam castings and stirrups; Fig. 12, a det-ail side view of a ring and eye used in the draft devices; Fig. 13, an inside view of the clip used in said devices, and Figs. 1li and 15 detail views of the handleplate.

The letter A designates the tongue, which 'through the forward beam-coupling K.

is of the divided or split type, and the letter B the sections of the axles, the two constituting the complete arch and being secured tof-'the tongue by means of blocks C, bolted thereto and receiving said sections. These sections are mounted on wheels of the ordinary type.

To cach section is secured a hanger composed of bars D, secured at their upper ends to a casting E, having a sleeve G, which tits over the section of the arch, and is held at adjusted positions by the set-screws II. To the lower ends of the bars is pivotally connected a beam-coupling composed of arms I, having openings in their ends to receive a vertical coupling-pin J, which passes down The upper ends of the arms I are divided, as seen in Fig. 5, and provided with a clampingscrew L, which acts to compress the divided portions and contract the diameter of the opening', so as to clamp the pin J and hold it in place. The forward coupling is further composed of a web M, which receives the pivot-bolt O, that passes through the hanger-bars D and forms the horizontal axis upon which the beams turn when they are lifted andlowered. These hangers are in duplicate, there being one at either side of the machine. The distance between the beams may be varied to suit circumstances, as the width of the rows of corn under cultivation, by adjusting the sleeve G from side to side. The web M has a series of holes in it to receive one of the draft-rods, as will appear hereinafter. Thus it will be understood that the beams are coupled to hangers and that. the hangers are sidewise adjustable. Each beam consists of two parallel bars P, whose rear ends are provided'with castings Q, preferably of the form shown in Figs. 10 and 11, having stirrups R to receive the operators foot when the machine is used as a ridingcultivator. These castings have a pivotal connection with a cross-head S by means of two bolts, which pass through the cross-head at a point to one side of its center, and also through the eye in the arms T of the casting, as also through a central eye formed in the eXtension'U of the casting. To this extension is bolted the handle-plate V. (Shown in IOO Figs. 14 and l5.) The wing XV of the plate is bolted to the extension through the openings X and Y, the slot Z, and the opening Z', the slot admitting of adjusting the wing at different angles. The wing A of the plate receives the handle, to which it is bolted, the series of holes B of which admit of adjusting the handles laterally.

The cross-head is preferably of the form shown in Figs. 8 and 9, having openings C', through one of which the extension U of the casting Q projects. The outer ends of this cross-head have recesses D' to receive the shovel-standards, as seen in Figs. 2 and S. These standards E' are of the usual type, and each carry a shovel of any approved type. -It is preferred to construct the beam-brackets Q with the stirrup R formed in one piece therewith, though the stirrup might be made of a separate piece and secured to the bracket.

' In Fig. 1l the extension beyond the eye that receives the coupling-plate is omitted, as that form of bracket is intended to be used with a walking-cultivator only.

l will now refer to the draft devices. These consist of singletrees F' and a doubletree G', secured to the tongue A. Suspended from the outer ends of the doubletree are draftbars H', having a series of holes therein, in which to engage the clevises of the singletrees F', according to whether the :machine is used as a riding or a walking cultivator. If as a walking-cultivator, then the clevis is hooked into one of the lower holes, so as to .draw upward and lighten the weight of the tongue upon the animals necks. If used a riding-cultivator, in which case the weight of the driver will be sustained by the rearward extensions of the tongue, the clevis is hooked higher up, as the drivers weight counterbalances in part that of the tongue. To

j this draft-bar is hooked a draft-rod J', jointed near the middle and arranged to be engaged either with a clip K', carried by the section of the arch inside of the wheel, or with the eye-plate L', carried by the outer end of the axle, both of which arrangements are shown in Fig. 2. It is convenient to connect these draft-rods in one or the other of these places, according as the sections of the arch may be adjusted with respect to each other. These several devices enter into the `direct draft O' is to prevent the vhangers from swinging back when the shovels are thrown into the ground. This arrangement of rods for bracing the machine and receiving the draftstrains is found to be very strong' and advantageous in practice. The plate of the clip K is shown in detail in Fig. 13, and will be seen to have two holes K", one to receive the rod M' and the other the rod J. This plate also has a boss L" concaved to lit the arch.

Referring now to the spring equipment, the letter a designates a collar having two arms Z1 and c, the collar being fitted to the arch between the members of the sleeve G. Each of the arms b and c has openings therein, the former above the latter, but of about the same 4radial distance from the axis of the collar a.

The arm c carries a chain d, which at its lower end is connected with a projection on the beam-coupling. The arm b connects by suitable links witha rod c, carrying at its lower end a plate f. A similar plate g is fitted around this rod and carried by the upper ends of a stirrup h, and a spiral spring is coiled around the stirrup and the rod c and litted between the plates f and g. The normal tendency of this spring is to elongate itself. stirrup h is engaged with the web M-of the coupling at a point much nearer the pivotbolt O than the connection of the chain d with the coupling, so that the latter has the greatest leverage.

The operation of this spring equipment is as follows: By taking hold of the handle and lifting' the beam enough to clear the shovels of the ground the arm b is ldrawn down by the spring t from the position shown in Fig. 3 to that shown in Fig. 6, during which movement the line of strain exerted by the spring moves away from the axis of the collar a, thus increasing the leverage of the spring. As this is taking place, the arm c is approaching the center of oscillation and losing in leverage. Thus the spring is gaining in leverage atone side and the resistance offered it lessening ou the other side ofthe center of oscillation of the double arm. The result is that the spring gains in advantage in excess of the loss of its tension, thus enabling it to assist in raising the beam with more and more power the higher the latter rises. The dotted lines in Fig. (i show a further movement of the double arm, with the arm c very much nearer the center. In this position the spring will sustain the beam-in an elevated position. Vhen the beam is depressed and the shovels are in the ground, the spring loses its leverage and the beam gains in leverage in the inverse order to that just described, resulting in depriving the spring of the ability to lift the beam. As the spring draws upon the forward end of the beam-coupling, and as its force, when the beam is down, is largely exerted against the support of the arm b, (the leverage being in that Vposition very short,) it acts to throw the shovels downward, with a tendency to maintain them in the ground. Another peculiarity of the device is if the chain be arranged to come in Contact with the coupling at the upper rear portion, as suggested in Fig. 3,. it will act against the descent of the beam, because of The f ICC IIO

the tendency to throw the chain out of a straight line, while the strain tends to draw it in such line. Thus the spring equipment has the quality of lifting or assisting in lift ing the beam, of suspending it when well elevated, and of holding it or tending to hold it in a position to maintain the shovels in the ground, while the position and arrangement ot' the chain incidentally arrest too great a descent of the shovels by the engagement of the coupling with the chain.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is- 4 l. In a cultivator, the combination, with an arched axle composed of two sections laterally adjustable with respect to each other, of a hanger carried by each section, brace-rods connected to the hangers, a coupling pivotal ly mounted in the lower part of each hanger, and a beam carrying shovel-standards and connected to each coupling by a vertical Vpivot-pin.
