ROLLER FOR LISTED CORN.

SPECIFICATION forming part of Letters Patent No. 440,015, datedNovember 4, 1890. Application filed May 6,1890. Serial No. 350,822. (No model.)

To all whom it may concern.-

Be it known that I, FRANK. J. CLARK, of Ashland, in the county of Saunders and State of Nebraska, have invented a new and Improved Roller for Listed Corn, of which the ioilowing is a full, clear, and exact descripion.

-My invention relates to rollers for listed corn, and has for its object to provide an attachment capable of application to any roller which will effectually smooth the tops of the hills and produce well-defined furrows between the hills, thus greatly facilitating the growth of the corn and its cultivation.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully described, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming apart of this specification, in which similar figures and letters of reference indicate corresponding parts in all the views.

Figure 1 is a plan view of the roller. Fig. 2 is a transverse section through a roller and the attachment thereto. Fig. 3 is also a transverse section through the roller and attachment, illustrating the means for increasing the exterior diameter of the attachment. Fig. 4 is a side elevation of one of the sections of the attachment, and Fig.5 is a side elevation of a modification of said attachment.

The rollers 10 may be of any suitable or approved construction. Preferably the trunnions 11 of said rollers are journaled in end bearings 12 and a central bearing 13, the end bearings being attached to a front board 14 and the central bearings to a tongue 15, which is also attached by braces 16 or otherwise to the front board 14. The bearings 12 and 13 usually consist of two metal straps having bearings formed at their outer ends, and the roller-trunnions are so held in their bearings that when desired they may be removed therefrom and the said rollers thereby disconnected from the frame.

The attachmentA is adapted to he slid upon the rollers whenever listed corn is to be rolled, and the-said attachment usually consists of a series of blocks 17, having a convexed exterior surface a and a fiat lower surface a, and at or near the center of the blocks an aperture a is produced. A sufficient number of blocks are placed side by side to more than surround the peripheral surface of the roller upon which the attachment is to be applied, and a rod 18 is passed through the apertures a of the blocks, thereby uniting them. What may be termed the upper connecting-block a is provided with two transverse apertures a and both ends of the rod 18 are passed through the apertures of this block, as best shown in Figs. 1, 2, and 3, and the contiguous face of the block at each side of this central or connecting block is provided with a recess 19, whereby nuts 20 may be screwed upon the extremities of the tie-rod, which ends are threaded and project one beyond each side face of the connecting-block. Thus by manipulating the nuts 20 the sections of the attachment may be drawn sufficiently close together to bind upon the roller and require no other fastening device. The attachment is preferably placed about centrally between the ends of the rollers, and while the central surface of the attachment is bulged or convexed the upper side surfaces are curved downward in the direction of the face of the roller, each block at its upper end surface being to that end concaved, as illustrated at a in Fig. 4:. Instead of making the central surface of the outer face of the attachment convexed, as illustrated, it may be slightly flattened, so as to produce a flat surface instead of a concaved surface between the rows of corn. If it is desired to swell the attachment, so as to make a deeper furrow, split rings or collars 21 are placed upon the exterior surface of the roller in such manner that when the attachment is applied thereto the inner side surfaces of said attachment will be brought in contact with the said rings, as illustrated in Fig. 3. To remove the attachment, the rollers 10 are removed from the frame in which they are journaled and the nuts 20 of the attachment are loosened, whereupon the latter maybe easily slid off at either end of the roller. Two rollers 10 are ordinarily employed in one frame, and as the machine is drawn forward the attachment travels between the hills of corn forming the rows, and the peripheral surfaces of the rollers at each side of the attachment are brought in contact with the top of the hills, thereby compressing or flattening them.

It is obvious that when listed corn is to be rolled, by placing the attachment upon an ordinary roller, which may be expeditiously accomplished, the clods of earth are effectually broken both in the furrows and upon the hills and the ground pressed closely upon the seed, thereby causing the ground to retain any moisture which it may contain for the proper nourishment of the seed.

In the modification shown in Fig. 5 the furrowing attachment A is made in two metal sections 22 and 23 only, which metal sections are hinged together at one end, one being provided at one end with a threaded rod 24, adapted to enter a socket 25 in the corresponding end of the other section, and when the said threaded rod is carried through the said socket a nut 26 is screwed upon the rod and the attachment of the modification to the roller thereby quickly effected. A spring seatsupport 27 is attached to the frame at its center, carrying at its upper end a seat 28 and preferably near its lower end a foot-rest 29.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. An attachment 'for rollers, consisting of a sectional furrowing-ring having a convex exterior and provided with means for securing it to a roller, substantially as herein shown and described.

2. The combination, with a roller, of a furrowing-ring consisting of a series of sections of greatest thickness at their center, atie-rod connecting the said sections, and an adjusting device attached to the said tie-rod, as and for the purpose specified.

3. The combination, with a roller, of a furrowing-ring constructed ofa series of blocks, having a convexed outer face, the connectingblock whereof is provided with two transverse apertures and the remainder with a single aperture, a recess being formed in the opposed faces of the blocks at each side of the connecting-block, and a tie-rod passed through the apertures of the various blocks, the said rod being provided with a locking device at its extremities, located within the said recesses, substantially as shown and described, and for the purpose specified.

FRANK. J. CLARK.
