SPECIFICATION forming part of Letters Patent No. 436,795, dated September 23, 1890.

Application filed July 5, 1889. Serial No. 316,518. (No model.) i

To all whom it may concern.-

Be itknown that 1, JOHN P. LHOMEDIEU, of Setauket, in the county of Suffolk and State of New York, have invented a certain new and useful Improvement in Cultivators, of which the following is a specification. I will describe a cultivator embodying my improvement and then point out the novel features in claims.

In the accompanying drawings, Figure 1 is a side elevation of a cultivator embodying my improvement. Fig. 2 is a plan or top View of the same. Fig. 3 is a vertical transverse section of one part or section of the same, taken at the plane of the dotted line ac m, Fig. 2, and looking in the direction indicated by the arrow at the end of this line. Fig. 4 is a longitudinal section taken at the plane of the dotted line 3 y, Fig. 2. Fig. 5 is a vertical section of. a bolt forming part of the cultivator. Fig. 6 is a side elevation of a cultivator of another kind. Fig. 7 is a plan or top view of the cultivator shown in Fig. 6.

Similar letters of reference designate corresponding parts in all the figures.

I will first describe the cultivator represented by Figs. 1, 2, 3, 4, and 5. It consists, essentially, of two parts. One part A comprises a number of drag-bars a. The other part B is a wheeled carriage, which is connected to the part A first mentioned.

The part A, as before stated, comprises a number of drag-bars. These are inclined downwardly at an obtuse angle from the front to the rear, the rear faces being shown as abrupt. The under sides or edges of these bars are preferably rounded at the extremities where they join the ends of the bars, as may be seen by reference to Fig. 3. The angle at the junction of the faces of each of these dragbars preferably has secured to it a shoe a, of steel or other suitable metal, to increase its durability.

The cross-bars aare shown as connected together by longitudinal bars a. I have shown two of these bars. The under side of these bars a may advantageously be recessed to receive the upper sides of the drag-bars. The

drag-bars and the longitudinal bars a may be secured together by bolts or other devices. 0 designates a shackle, which may be made under the axle.

of any suitable metal bent between the ends to form an eye, and having its two end portions bent to diverge and turned at the extremities so as to form pivotal connections with eyebolts 0, here shown as secured in the forward portions of the longitudinal bars a of the drag A. This shackle, owing to its pivotal connection with the drag, may swing upwardly and downwardly. shackle C has pivotally connected to ita clevis D. To the boltofthis clevis the whiffle tree or harness of an animal or animals employed to draw the cultivator through the field may be attached.

The wheeled carriage or section B is shown as consisting of a pair of wheels b, fitted to an axle b. To the axle b a block b is secured. It is here shown as arranged upon the upper side of the axle. It may advanta geously be made of wood. Connected with it are two bars 5 which may also be made of wood and extend at right angles to the axle, and hence forwardly and backwardly. These bars b are connected by a bar I), extending parallel to the axle, and also by a bar I), which likewise extends parallel with the axle. A pole 1) extends under the bars 12 and b and It is shown as held to the axle by means of a loop or strap b, which may be made of any suitable metal and secured to the axle. It is shown as similarly secured by a loop or strap b to the bar b The pole b owing to its being connected in the manner described with the axle and with the bar 19 may be slid in the direction of its length so as to project a greater or less distance in front of the bar I). Abolt I)", passed through the bar b, may be engaged'with any one of a number of holeswithwhich the poleis provided so as to securethe pole in the different positions into which it may be adjusted relatively to the barb. A seat b is supported by the bars b. As here shown, it does not rest The eye of the directly upon the bars, but upon rails or guides 5 the axle or more or less in front of the axle.

It maybe secured in position by any suitable clamp, or it may be adjusted and maintained in position by the occupant. The pole b is provided with a pin 19 and an eye I). The pin 1) engages with a plate or flange 19 which is formed with a two-armed bolt 17". This two-armed bolt enters sockets provided in a bar a which is secured to and extends between the two bars a and about midway of their length, so that the weight desired will be approximately near the center and cause the drag to bear evenly on the ground. The double-armed bolt Will be incapable of'turning, but the pin 19 can turn relatively to it; hence the wheeled carriage or section B can swing relatively to the dra -section A.

A chain E is secured at one end to the eye I) of the wheeled carriage or section B, and passes thence through the clevis D, and at the end is fastened to itself. This chain secures the wheeled carriage or section B to the clevis D so that the draft of the animal or animals shall be not only upon the drag-section A but upon the section B. The drag pulverizes the earth and also grades and levels it. The animal or animals may be guided from the wheeled carriage-section B.

The wheels of the carriage-section B are considerably back of the drag-section. They are intended to be large and light so as not to seriously affect the soil. By adjusting the connection of the bar 19 with the pole the distance from the wheels of the drag-section may be varied. The draft will be divided between the drag-section and the wheeled carriagesection so that the animal or animals cannot lift the drag. It will be seen that there will be no weight upon the animal or animals. The seat may be adjusted to produce exactly the weight which it is desired to exert upon the drag-section. Of course the wheeled section can adjust itself to the drag-section for passing around curves.

In Figs. 6 and 7 I have shown the same construction of wheeled carriage-section B, but instead of the form of drag-section A which was represented in the primary example of my improvement I have shown a drag-section in the form of a harrow. The two sections are combined in this example of "my improve ment as in the other. The shackle O is of substantially the same construction as that in the first example of my improvement, although here, instead of having its ends bent to form pivots engaging with the eyebolts c, the ends embrace abolt which extends through the eyebolts c.

I have shown the harrow as provided with eyebolts G from the rear bar. With either of these eyebolts may be engaged a lever H,

having a pointed end and made of such length as to enable it to bear upon the bar 19 of the carriage-section B for a fulcrum and to ex tend within reach of the driver. By engaging the lever with one of the eyebolts and oscillatin g it upon the bar 19 as a fulcrum, either side of the harrow may be tilted at will during its operation, or, if preferable, while it is at rest.

All the advantages of regulating the weight upon the dra -section in the first example of my invention can be realized with the harrow in the second example of my invention.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. In a cultivator, the combination, with a carriage-section, of a drag-section having a shackle pivoted thereto, a clevis, a chain, and a double-armed bolt uniting the drag and carriage sections, substantially as specified.

2. In a cultivator, the combination of a drag-section having rearwardly-inclined bars, a carriage-section connected to and bearing upon the drag-section near its center, and a draft attachment engaging with the carriagesection and with the drag-section, whereby the strain is divided equally upon the dragsection and carriage-section, substantially as specified.

, 3. In a cultivator, the combination of a drag-section, a carriage-section, and a doublearmed bolt b engaging with the drag-section, and a pin on the carriage-section engaging with a flange or plate of the double-armed bolt, the said carriage-section'bearing down wardly on the drag-section, substantially as specified.
