SPECIFICATION forming part of Letters Patent No. 331,738, dated December 1, 1885.

Application filed September 9; 1885. Serial No. 176,623. (No model.)

To all whom it may concern:

Be it known that I, HARLOW G. STAHL, a citizen of the United States, residing at Fremont, in the county of Sandusky and State of Ohio, have invented certain new and useful Improvements in Cultivators; and I do here by 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, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

This invention relates to cultivators of the kind as shown in the patent to M. Bruner, J r., No. 100,720, dated March 15,1870; and it consists in the detailed construction and combination of parts, hereinafter fully described and claimed, by which the construction and working of the cultivator are improved and facilitated.

In the drawings, Figure I is a plan View of thecultivator, looking downward from above. Fig. II is a side view of the cultivator with one of thewheels removed. Fig. 111 is a rear view of the machine. Fig. IV is a detail plan view of larger size, showing the attachment of a main standard-rod, a seat-bar, and the axle with the frame of the machine. Fig. V is a rear view of the same. Fig. VI is a side view of the same. Fig. VII is a detail end view of one of the steps, showing the plow-beam in cross-section. Fig. VIII is a side view of the step.

Similar letters of reference indicate corre sponding parts in all the figures.

The framing of the cultivator consists of two side bars, A, and a center bar, A. These bars are secured to the axle by clips, and to one another by the cross-piece a. The side bars, A, are also secured to the lower part of the axle by the braces :1

Bare the plow-beams, provided with curved draw-bars G at their front ends, which are pivoted to the side bars, A, in any convenient manner. Each plow-beam consists of two diverging parts, which are united toward the front, where they are joined to the draw-bar.

D are the cultivator-standards, or teeth,

which may be secured to the plow-beams in any convenient manner.

E are the main standards, pivoted to the plow-beams at their lower ends, and having their upper ends pivoted in and supported by the main standard-rods F. A chain, 6, is provided which couples the main standards together and prevents the plow-beams from spreading too far apart. Each main standard is provided with a bolt, e, at the bottom, which also passes through the diverging parts of the plow-beam, between which the said main standard is placed, with a hole, 6, near the top end for engaging with the loop of the rod F, and with a collar, 6 provided with a projecting hook, e, at the extreme top for the attachment of the spring-chain.

G are the spring-chains, each of which is provided with a spring, These chains connect the tops of the main standards with the side bars, A, in front of the rods F, and prevent the cultivatonteeth from penetrating too far under the surface of the ground. The springchains also sustain the teeth in a manner pleasant tothe operator and team, greatly relieve the draft, make the side movement of the beams much easier in avoiding irregular hills, and enable the operator to make the teeth penetrate deeper than common, where necessary in passing over dead-furrows, by pressing on the step, and thus distending the spring.

H are the lug-brackets bolted to the side bars, A, for'sccuring the outer ends of the rods F. The inner ends of rods F are secured to the lug-bracket H, which is bolted to the center bar, A. The ends of the rods F are flattened, and are provided with an elongated hole, f, through each of them. The brackets H and H are provided with lugs h, circular in form, projecting from them, for the attachment of the main standard-rod ends. Each log it has on one side close to the end of it a projection, h, which prevents the said rods F from coming unfastened when the cultivator is at work.

In order to attach the rods F to the lugbrackets, the machine must be tilted up, or otherwise placed in such a position that the elongated holes f may be slipped over the projections h of the lugs. It will be noticed that the brackets H have one lug, and that the center bracket, H, has two similar lugs, to which the ends of the rods F may attach. The two looped rods F, and the main standards to which they are attached, are therefore kept perfectly distinct, and the two halves of the cultivator can be moved in all directions independently of one another.

I is a tool-box, which may conveniently be attached to the center bar, A.

J is the seat for the driver, securely fastened upon the. spring 9', and suspended from the ends of the two seat-bars K by means of the pins j, which project upward from the collars j secured on the ends of the said seat-bars, and which pins engage with any of a series of holes, 9' in the seat-spring. The seat-bars K are made removable from the side bars, A, to which they are connected, and can be drawn back and forth, as found convenient, so that the seat J may be placed nearer to or farther away from the main standards E. The front ends of the seat-bars K are made rectangular in section corresponding with the side bars, A.

k are loops through which the ends of the seat-bars pass. These loops pass from the top and bottom of the side bars, A, round the outside of the seat-bars, and the same bolt by which these loops are attached to the side bars may conveniently serve as an attachment for the spring-chains, and also secure the ends of the cross-piece a and the braces a The seatbars K are further supported by the troughshaped pieces which are clamped in between the axle and the side bars, A, and have their flanges uppermost to retain the seat-bars in position laterally.

L is the axle of the cultivator, firmly secured to the bars A A of the frame by straps land suitable bolts which pass through the said bars and also secure the lug-brackets to them. The ends of the axle are bent downward and outward to form journals for the wheels M, which may be of any approved construction.

In order to overcome the tendency of the seat-bars to draw inward the side bars, A, when the weight of the driver is on the seat, the axle has two creases or depressions, Z, formed in it while being bent. The straps Z, which secure the axle to the side bars, A, are placed in these depressions, which correspond with them in width, and the side bars are thereby held rigidly in position.

N are the steps, each of which has holes n passing through it. These holes are placed in the middle of the width of the step, and far enough down from the top to come opposite to or a little below the middle of the plowbeam. Each step is curved on one side, so as to form a shoulder, n, which presses against the under side of the plow-beam. The sides of the steps having the holes n in them are placed between the diverging parts of the plow-beams and the lower ends of the main standard. The bolts 6 pass through the said steps, plow-beams, and main standards, and the shoulders n, and prevent the steps from rocking.

R is a double-tree attached to the center bar, A, by means of the bolt 1".

r is a distance-block placed between the double-tree and the center bar.

0" is the hammer-strap for supporting the lower end of bolt r.

S are the trace-carriers attached to the ends of the double-tree by bolts .9 and straps 8. Each trace-carrier is provided with suitable hooks, by which the traces are fastened to it. The object of this form of construction is to reduce the height of the traces above the ground to a convenient level, so that the inner traces may be kept from entanglement with the attachments by which the draw-bars are secured to the side bars, and so that all unnecessary weight may be taken 0d the necks of the horses.

Having thus described myinvention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a cultivator, the combination of the plow-beams,the main standards, the looped rods F, provided with flat ends having elongated holes in them, the lug-brackets H, and the lug-bracket H, so that the plow-beams can be worked independently of each other, substantially as described and shown.

2. In a cultivator, the combination of the plow-beams, the main standards provided with collars e having hooks e projecting therefrom, the main standard-rods F, pivoted to the framing of the cultivator, the side bars, A, and the spring-chains G, having springs g, for connecting the tops of the main standards with the said side bars and limiting the downward movement of the cultivator-teeth, sub stantially as described and shown.

3. In a cultivator, the combination of the removable and adjustable seat-bars K, the spring-seat J, attached to the rear ends of the said seat-bars, the loops in, bolted to the side bars, and the trough-shaped pieces k, clamped between the said side bars and the axle, substantially as described and shown.

4:. In a cultivator, the combination of the steps N, provided with the bolt-holes n and shoulders at, the plow-beams B, main standards E, main standard-rods F, pivoted to the framing, and the bolts 6, substantially as and for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.
