GRAIN-DRILL ATTACHMENT.

SPECIIEICATION forming part of Letters Patent No. 266,325, dated October 24, 1882.

Application filed February 18,18E'2. (No model.)

To all, whom it may concern.-

Beit known that I, PERRY HARRISON SMITH, a citizen of the United States, residing at Topeka, in the county of Shawnee and State of Kansas, have invented certain new and useful Improvements in Grain Drill Attachments; and Ido hereby declare the followingto beafull, clear, and exact description ot' 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 accom panying drawings, and to letters or figures of reference marked thereon, which form a part ot this specification.

This invention has for its object to furnish a roller attachment for the various kinds of seed-drills known as hoe-drills, whereby a separate roller will be provided to follow in the furrow formed by each lloe.

rlhe invention consists in arranging the rollers in pairs, the rollers of each pair being on opposite ends ot' an axle pivotedat its center, so that it has a rocking or seesaw movement, whereby the two rolls readily adjust themselves to an uneven surface.

ltconsists, further, in the arrangementof the several pairs of rolls, in combination with the frame, whereby each pair will have an independent vertieal movement or adjustment, so that it will readily pass over knolls or other obstructions.

lt consists, further, in having the drivers seat and the arms or levers which support the pairs of rolls so combined that the weight of the driver is equally distributed over all the rolls.

lt consists, further, in the combination and arrangement of the several parts hereinafter fully described.

ln the drawings, Figure lis a perspective of my attachment having a portion of the iirst roll removed. Fig. 2 is a side elevation of the same; and Fig. 3 is a rear elevation, showing two pairs ot' the rollers with their coupling devices.

This invention is intended to be attached to any ordinary drill. I have not therefore shown a drill in the drawings, but show two hoes, A A, in position in front ot the rolls, together with the t'urrows B B, opened by said hoes, and

,pair ofthe arms f f the wheels GG, composing one of the pairs supported on their axle D and running in the furrows B.

e is a head-bar having alength about equal to the width of the ordinary drill. It has fastened to it in suitable position two or more coupling-arms, e. Only one ot' these coupling-arms is shown. rEhe others are arranged at proper distances apart, and by them the head-bar is coupled to the drill-carriage.

ff are two arms, which have their forward ends attached to the head-bar e, and their opposite ends extended to the rear and provided with bearings adapted to slip onto the spindles D' D of the axle D and retain the latter in proper place. The arms ff may be provided i'rom a single bar of metal having its rear end bifurcated; or they may be separate bars, as shown. I have shown but a single as applied to one ot' the outer pairs ofrolls. armsare provided for each pair ot' rolls, and arranged in saine manner as the arms ff. rlhe axle D has its spindles put through the bearings in the rear ends of the arms ff. rlhe hubs of the wheels c c ordinarily bear against the arms or against a washer first placed on the spindle against the ends oi' said arms. The axles ot' the two end pairs of rolls are pivoted at their centers to the lower ends of vertical standards g g, so that they will have an oscillating or seesaw movement, whereby either one ofthe rolls in said pairs may be drawn over a clod, knoll, or other slight elevation without raising the other roll in said pair. rI he barsf j' are suitably connected at their forward ends to the head-bar e, so as to permit this oscillating movement of the axles D. rlhe standards It will be understood that.

g g have their upper ends carried above the l peripheries of the rolls, and have placed on them a cross-beam, g', thelatter being secured so that it will have a slight tilting movement on its fastenings. The object of this tilting movement is to permit the pair ot' rollers at one end ofthe series to be lifted over any little kn0ll,'clod, or other slight elevation without disturbing the position ot' the pair of rollers at the other end ot' the series, and also relieve the vertical standard from the strain which would result it' the cross-beam g were IOO fixed rigidly thereto. lhe standards g are supseveral parts hereinbetore described.

ported by braces g2, which extend to and are made fast to the head-bar e, as shown.

The device shown in the drawings has four pairs of rollers. The pairs E E are placed at the ends, and the pairs E E are arranged immediately in the series, forming two sets ot' four rollers, each set being composed of one end pair and one intermediate pair. The end pair of rollers is supported as hereinbefore explained. The intermediate pair next the end has its axle held in bearings in armsj'f, similar to the supporting of the axle of the end pair. To the middle of the axle of the next intermediatepair the lowerend of a vertical bar, h, is pivoted. The upper end ofthe bar L extends nearly to the cross-beam g, room being left for the vertical play hereinafter explained. The upper end ot' the bar 7o is pivoted to one end ot' a horizontal equalizing-bar, It. and the other end ofthe equalizing-bar is pivoted near to the upper end ot' the standard g. The equalizing-bar h is preferably made in two pieces arranged parallel to each other, with their ends embracing the bar h and standard g, as shown. When the intermediate pair or' rollers is thus coupled to the end pair it will be seen that either pair can have avertical movement independentlyof the other. rIhere is pivoted to the bar h, atthe middle point between the bargand the bark, thelower end of the supporthz, the upper end of which is carried upward through a slot, g3, in the cross-beam g. The end ot' the seat-bar K rests on the top ot' the support h2. I have described one set ot' two pairs of rollers. lt will be seen that the construction, arrangev ment, and coupling together of both sets is exactly the same, and that the seat-bar rests on the ends ofthe two uprights or supports h2, and that the pressure made by any weight placed on and at the middle of the bar K will be distributed equally to all t'ourof the pairs ot' rollers. This equal distribution is effected by the peculiar construction and arrangement ofthe The drivers seat K is fixed at the middle of the bar K; but in case more pressure be needed on one set of four rollers than on the other the driver can easily transfer his weight for the time being from the seat K along the bar K and over the rollers requiring increased pressure.

It will be seen that 'by the construction and arrangement ofthe several parts, as hereinbcfore described, I secure an adjustmentofthe two rollers in each pair by means ot' the oscillating axle, a vertical adjustment 0f each pair ot' rollers independently ot' all the other rollers, and an adjustment of one set of four rollers independently ofthe other like set.

Having thus described my invention, what I claim, and desire to secure by Letters Patent,

l. The combination, with the frame for car. rying the rollers, of an axle provided at its opposite ends'with spindles and pivoted at its middle to the framing, and the two rollers placed on the spindles of the oscillating axle, and arranged in rear of and so that they will ltravel in the furrows formed by the shovels on the seeder-frame, substantially as set forth.

2. In a roller attachmentfor grain-drills, the combination, with the frame, of a series of rollers arranged in pairs, each pair being coupled to an adjacent pair, and having an independent vertical movement or adjustment, substantially as set forth.

3. The combination of the pair ot' rollers E, the standard g, cross-beam g', having slots g3, ofthe pair ot' rollers E', support h, equalizer' L, support h2, and seat-bar K, substantially as set forth.

In testimony whereof I aix my signature in presence ot' two witnesses.

PER tY II. SMITH.
