TO ALL WIIOM I'I MAY CONCERN:

Beit known that I, H. S. CONNELLY, of Clymer, in the county of Chautauqua, and State of New York, have invented certain new and useful Improvements in Combined Field-Rollers and Seed-Servers; and I do hereby declare that the following'is a full and exact description thereof, reference being had to the accompanying drawings, making part of this specification.

Figure 1 is a plan of my improved machine.

Figure 2, a rear elevation with the rear roller removed.

Figure 3, a central vertical transverse section.

Like letters of reference indicate corresponding parts in all the figures.

It is the object of my invention to produce a combined held-roller and seed-sewer, in which the inner journals of the two main rollers shall rest in adjustable bearings connected with the seat, so as to have an :action independent ofthe frame; also to s o arrange the slides in the partitioned seeding-box that they may be relatively adjusted to act so as to allow a greater or less quantity of seed to be dropped, by which two different kinds of seed may be properly mixed in sowing.

As represented in the drawings, A is afframe of suitable construction, having liked vertical bearings a a at the extremities, in which rest the outer journals or gudgeons Zi I), of a pair of rollers, B B, situated under the frame. The inner journals or gudgeons Z1 b of said. rollers, instead of resting in fixed bearings in a similar manner, rest in adjustable bearings e c in the form of standards or bars, which run up through slots in the frame, and are preferably connected loosely by joints made up of elongated tenons d cZ, and mortises e e, to a cross-arm,f, which is centrally pivoted in turn to the back of the seat C. In order to retain the sliding bearings in place, they rest in suitable guides y g, attached to vertical hangers 7L 7a, extending down from the main frame in the same manner as ft a. 'The seat is also preferably provided with a vertical guide standard, z', which retains it in its proper position as it works up' and down. By thus connecting the inner journals of the main rollers with adjustable bearings, the rollers can adapt themselves'to any inequalities ofthe ground, as indicated in fig. 2; and thus the soil will receive a uniform and unvarying pressure. By connecting these sliding bear* ings with the seat, it will also be noticed that the weight of the frame will come upon the outer journals of the rollers, while the weight of the driver will come upon the inner journals. In this manner the weight will be nearly divided, which insures nearly an equal degree of pressure upon both ends of the rollers,.and of course this equalizes the action on the soil. Were the pressure to come wholly upon' the outer journals, the inner ends of the rollers would act upon the soil only to the extent of their own gravity, and the rollers would also incline or tip. It also prevents, in a great degree, the strain that would otherwise come upon the outer journals and the main frame, and it'insures a great saving of power in passing over stones and other obstructions, which, if the rollers were stili', would have to raise the main frame, driver and all. The connection of the sliding bearings with the seat by means of the pivotcd cross-arm f, and the joints made up of the elongated tenons d, and Inor- `tises e, allows the one scatto be combined with the two rollers in such a manner as to produce the necessary pressure on each. And at the same time it will be perceived that each roller may have a free upward and downward adjustment without affecting the other roller. rIhis latter ciiect is accomplisned bythe peculiar joint used in connection with the cross-arm, the tenen d of cach bearing having a range motion before it actuates the cross-arm. This effect is of much importance in insuring the free adjustment of the individual rollers.

`Over the rear of'veach roller B is situated a scraper, G, pivoted at one end, at 7c, to the bearing a, while the opposite end'is free to rise and fall with the roller, sliding up and down in a guide, Z. When it is desired to retain it in an elevated position awayfrom' the roller, it is held up by a pin, m, resting under it. These Scrapers conform to the surface of the rollers as they adjust higher orv lower, and scrape from them all dirt that may cling to their peripheries. In the rear of the two main rollers B B is an auxiliary one, B', which follows mid way between them, and acts upon thc soil left by the brake of the main rollers. In order that the rear roller should act upon the brake as the machine turns in either direction, I connect its tongue, n, with the main frame, by a loose joint, preferably made up of a hook and staple, o. This rear roller has also a scraper, Gr; but since the roller is free in its actions at` all. times, this scraper is not pivoted at either end, but slides up and down freely in guides Z Z. When it is elevated, it strikes two stops pp, and is held by a pin, m. rIethe front side of one end ofthe main frame is hinged an arm, I-I, which sustains at its extremity the seed trough or box I, the opposite end being sustainedby a rigid arm, To, the hinged arm is secured a hanger, g, having a friction gear-roller, 1', resting on one end of the ladjacent roller B, by which it receives motion. On the outer end of shaft s ofthe gear-roller is a cam-wheel, t, which imparts motion to a head, u, vto which the seed slides K K are secured by means of screws w w, passing through slots :c fc, as shown most clearly in tig. 1.- The slides K K may be two'or more in number, as may be desired, resting in longitudinal compartments v c of the seed-trough. The construction of the slides is ordinary, having covers g/ y that slide over holes z z in the bottom ofthe compartments. By'the employment of the screws and slots w x, connecting .the seed-slides with the head u, it will be seen that said slides may individually be made to cover more or less ofthe holes z z in the bottom of the compartments, and consequently more or less amount of seed may be allowedv to escape. In this manner I am enabled ito mix different kinds or qualities of seed in sowing much more eiectually than can be doneby agitating them in one compartment; in which case, one kind being heavier or smaller than the other, will fall to the bottom rst, and the whole be unequally distributed. In my arrangement it will be seen that if two kinds or qualities are to be sowedtogether, the mixture may be exactly gauged by covering or uncovering the holes'ot` the respectivecompartments correspondingly. Itis also a convenient arrangement for sowing plaster, &c., with seed. When the field-roller is to be used alone, the sewer may be disconnected by simply drawing the pin out out of the hinge that connects the arm H with thel main frame, and then detaching it from the'rigid arm H.v

In going into the field and turning corners and passing obstructions, the hinged end of the sower may be slightly raised to disengage the gearing, by means of a concentricnlever, L, secured tothe arm H.

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

1. Resting the inner journals ofthe main rollers in adjustable bearings, 'and connecting said bearings with the drivers seat, substantially as and for the purpose set forth. I

2. The combination of the cross-arm f with the adjustable bearings c c and the seat C, for the purpose of allowing the one seat to act upon the two rollers, substantially as specified. l

3. The combination, with the subject-matter of the preceding claim, of the joints formed of the elongated tenons oZ and mortises e, for allowing each roller an independent action, as specified.

4. The combination of the pivoted Scrapers G with the adjusting roller B, as shown and described, and'for the purposes specified.

5. The arrangement of two or more seed-slides K K, resting in compartments v v, and connecting by screws and slots w or equivalent, with the single head u, in such a mannerthat the escape of the contents of' each compartment may be exactly gauged to produce the desired mixture, as specified.

6. The special construction and arrangement of the machine, as herein set -forth.

In witness whereof I have hereunto signed mymamc in the presence of two subscribing witnesses.

H. coNNnmY.
