SPECIFICATION forming part of `.'.lietters Patent N0.'270,369, dated January 9, 1833.

/ Application tiled J nly 17, 1882. (No model.)

al'o all whom z'i may concern:

Be it known that I, THOMAS M. BARNA, of Atlanta, in the county of Fulton and State of Georgia, have invented certain new and useful Improvements in Cotton-Planters; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification, and in which- Figure l is a perspective view of a cottonplanter embodying my improvements. Fig. 2 is a perspective detail view of the furrowopener and soil-leveler with its roller. Fig. 3 is a sectional view of the latter with its standard. Fig. 4 is a detail view ot' the coveringdisks and their appurtenances. Fig. 5 is a sectional detail view ot'one end of the central axle which supports the rolling hopper and its bearing in the frame, and Fig. 6 is a vertical cross-sectioii through tlie front roller and its standard.

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

My invention has relation to cotton-planters or cotton-seed drills of the class having rotary hoppers; and it consists in certain improvements upon the machine for which Letters Patent of the United States No. 216,548 were granted to me on the 17th day of June, 1879.

The first part of my improvement has relatiou to the device for opening the furrow which is to receive the seed, and the second part to the means employed for covering the seed after it has been deposited in the furrow. I havefurther improved the means for hanging the rotary hopper in its frame in such a manner as to insure its perfect operation at all times and under all circumstances.

In the accompanying two sheets of drawings, the letter A represents the traine; B, the tongue, and C C the handles.

D is the rotary hopper, which may be ofany approved construction; but I prefer a construction substantially like that shown and described in my Patent No. 216,548, with the ,difference that I make the hopper cylindrical instead of barrel-shaped, and of sheet metal instead of wood.

E E are the wheels, which are integral with the heads ofthe hopper.

To the under side of the tongue is bolted the combined furrow-opener and soil-leveler, which is in the nature ot' a plow having a ti'iangular downwardly-projecting point or share, F, and two sweeps, Gr Gr, extending rearwardly in an oblique direction from the base of the share, so as to project beyond or overlap the wheels. Back of this device is a standard, H, bolted to the rearwardly-extended part of the tongue, and having a series of three ormore holes in its ylower end t'or the. insertion ofthe bolt li, upon which the roller I revolves. The latter is of the shape shown iii cross-sectionin Fig. 6, it having a V-sliaped periphery with slightly-rounded sides. 'As the machine advances over the ground the triangular share F will open a triangular furrow, the excavated soil from which is swept to both sides. and smoothed or leveled by the oblique sweeps G G, and the roller I, entering the furrow iinmediately back-of the opener, operates to slightly compress its sides, so as to prevent its tilling up until after the seed has been deposited. Roller I may be adjusted up or down in its standard H to tit any depth of furrow made by the opener.

In the rear part of the frame, back of the axle n, is hung a frame consisting of-two side pieces, JJ, connected at their outer ends by a curved cross-bar, K. A

-L and L are the concave rotary coveringdisks, which are hung obliquely upon crossbar K, so as to approach each other atl their rear ends and form a wedge-shaped space or opening between them.

M is a roller, which is hung in arms in, pivoted in the outer ends ofthe side pieces, J, and bearing against lips or projections j, which control the downward play of tlie roller-arms mand ofthe roller. This covering device may be raised or lowered by a rod, n, which works through a staple on the upper cross-bar ot the handles, and may be held in place by a pin IOO Between the boxes A of frame A, in which the axle a of the rotary hopper is journaled, and the disks or wheels E, is placed on each side a movable hub, made in two parts, O and 0', as shown more clearly in Fig. 5 ot' the drawings, each of which has an inwardly-projecting tongue, o and o', adapted to fit in and get lost.

By the construction and arrangement ot' the concave rotary covering-disks L L, mounted obliquely upon bar K, in conjunction with the adjustable roller M, the soil is built up over the seed deposited in the furrow and cornpressed so as to ei'ectnally cover and protect it.

Having thus described my invention, I claim and desire to secure by Letters Patent ot' the United States- 1. In a cotton-planter, the combination, with a rotary hopper, of the furrow-opener consisting of the downwardly-projecting triangular share F, having the fiaring oblique sweeps G G, extending rearwardly beyond the wheels of 3o the hopper, and vertically-adjustable roller I, adapted to compress the sides of the furrow made by the opener, and of the covering dcvice consisting of the hinged frame J, cross bar K, concave disks L L, journaled obliquely upon said cross-bar, and roller M, all constructed and arranged substantially as shown and described, for the purpose set forth.

2. In acotton-planter, the combination of a rotary hopper, D, having axle c, notched or grooved at a and af, frame A, hm'ingjournal` boxes A', removable hul) consisting of the halves 0 and 0', having tongues o and o' at their inner ends, and annular spring I, constructed and combined to operate substantially as and for the purpose shown and described.

In testimony that I claim the foregoing as my own I have hereunto atxed my signature in presence of two witnesses.

THOMAS M. BARNA.
