DRILLING ATTACHMENT FOR CORN-PLANTERS.

SPECIFICATION forming part of Letters Patent No. 574,208, dated December 29, 1896.

' Application iiled March 13,1896. Serial No. 583,063. (No model.)

.T LZZ whom, it r11/ay concern;

Be it known that I, RODERICK MURoHisoN, a citizen of thel United States, residing at Kewanee, in the county of Henry and State of Illinois, have invented certain new and useful Improvements in Drilling Attachments for Corn-Planters, of which the following is a specification. v

The invention herein described relates to 1o improvements in corn-planters and the leading object of the invention is to provide drill- .ing attachments for that class of check-rower corn-planters in which an intermittently-rotating seed-cup disk or wheel in the seedboX and a discharging valve or valves in the seedtube are operated by arock-shaft, which rockshaft is given motion in one direction by a tappeted check-row line stretched over the ground being planted and in an opposite or zo everse direction by a spring or equivalent device.

- Further objects of the invention are to provide such drill attachments for check-rower corn-planters of the class described, which at- 2 5 tachments are simple and cheap in construction, certain and efficient in action, readily and easily applied to different makes of checkrowers of the class referred to, not liable to get out of order, which will not operate in 3o backing the machine, and can be easily and quickly thrown into and out of gear with their operating mechanism.

For the purpose of carrying out these objects the invention consists in novel struc- 3 5 tural features and novel organization and combinations of parts,th e operations of which parts as organized and combined are hereinafter fully described, and the construction and combination of which parts are made the 4o subject-matter of the appended claims.

In the accompanying' drawings,which illustrate my invention, Figure 1 is a top plan of one side part of a` check-rower corn-planter with part of the wheel-rim broken away and the seedbox in section embodying my invention. Fig. 2 is a side elevation of the parts shown at Fig. 1 with the check-row line removed and part of the wheel broken away; Fig. 3, a sectional elevation of parts 5o and side elevation of other parts in the line 3 3 in Fig. 1, but showing a portion of the drill attachment differently adjusted from that shown at Fig. l; Fig. 4, an enlarged top plan of a portion of t-he drill attachment; Fig. 5, an enlarged sectional plan of the seedbox and plan of parts adjacent thereto; Fig. G, an enlarged side elevation of the lower part of the secdbox and upper end of the seed-tube and adjacent parts, partly in section and partly in elevation; Fig. 7, an en- 6o larged side elevation, partly in section, of a portion of the drill attachment.

My drilling` attachment can be applied to any check-rower corn-planter of that class or type in which a rock-shaft operated by a check-rower line having tappets is the medium through which intermittent rotary motion is given to a seed-cup disk or wheel in the seedbox and a seed-discharging valve in the seed-tube. 7o

In the present instance I have shown the invention adapted to a check-rower planter of an ordinary type and ordinary construction, with transverse frame-bars 1, side frame-bars 2, braces 3, split wheels 4, seedboXes 5, seedcup disks b', rock-shaft 7, forked levers S, runners 9, seed-tubes 10, seed-tube valves 11, valve-openers 12, and check-rower line 13 with tappets 14,' the operation of which is in an ordinary manner and may be briefly de- 8o scribed as follows:

A forked lever 8, contacting successionally with the tappets 14 of the stretched wire, will be swung rearwardly thereby and will thus give a swing or oscillatory movement in one direction to the rock-shaft 7, and this movement of the rock-shaft, by means of the radiusarln 15, connected with the rock-shaft, will give a forward throw to the pawl 16, and its forward end coming in contact with one of the 9o ratchet-teeth 17 on the under side of the seedcup disk 6 will give a partial rotation to said disk and bring one of its holes or cups 19, with its charge of seed, under the cut-off 20 and over the discharge-opening 21 in the bot- 95 tom of the seedbox, whence it passes downward in the hollow tube 10 to the spring-valve 11 and is there detained until discharged by the downward movement of the valve-opener 12, which occurs at each succeeding movement in the direction described of the rockshaft, by means of the radius-arm 22, which projects from the rock-shaft and is pivotally connected with the valve-opener 12. When the forked lever escapes from a tappet 14, the spring 23, which connects a forked lever with IOO an arm 24, projecting from a l`ra1ne-bar, will give a return movement tothe rock-shaft and thus restore the pawl 1G to its normal position and also retract the valve-opener 12 to its normal shown position. The pawl 1G is held in contact with the ratchet-teeth 17 by means of a spring 25, andthe seed-cup wheel is held from backward movement by means of a spring-actuated detcnt-pawl 2G. Ordinary guide-pulleys 27 direct the cheek-rower line properly to the forked lever. An ordinary line-doi'er 2S is shown, but need not be herei n described. The seed-cup disks 6 are substitu tive in the usual manner for others having larger or smaller seed-cups for varying the quantity or number of seed dropped in each hill and for thinner disks and small seed-cups for dropping a single grain in each charge.

When the drilling attachment is used, the check-rower line is dispensed with and a thin seed-cup plate is used in the seedbox to separate single grains of seed from the mass in the seedbox and deliver such charges of single grains to the seed-tube at each intermittent movement of the seedscup plate or disk. The drilling attachment in this instance comprises a bent arm or lever 2f), having an integral hollow journal 30 projecting laterally therefrom and through a bearing 3l, which is fixed to a plate 32,that is bolted to a side framebar 2. The journal 30 is held in the bearing 3l bya bolt 33. (See Fig. 4.) The arm or lever 20 has an extension 34 hinged toits rear end part by a pivot-pin 35, Fig. 7, in such manner that said extension may be oscillated or swung in a vertical plane; The downward swing of this extension is limited by shoulders 3G thereon coming in contact with shoulders 37 on the rear end 38 of the main part of the lever, Fig. 7, and its upward swing is limited by shoulders 39 thereon coming in contact with the upper side of the main rear part 33 of the lever, as shown by full lines at Fig. 3 and dot-lines at Fig. 2, in which turned-back position it will sustain itself, as its upper portion is inclined back of or past its pivotal point. 'lhe outer end of the forward end part 40 of the arm or lever 29 is pivotally connected by a link 4l with the outer end of an upwardlyprojecting radius-arm 42,whieh projects from the rack-shaft 7. lVhen the extension 34 is in its horizontal position,as shown by full lines at Figs. l, 2, and T, its rear end part is within the orbital path of a circular series of tappetpins 43,which project axially from an annulus or ring-shaped plate 44, which is bolted to the spokes of one of the plan ter-wheels. The anuulus 44 may be otherwise constructed and fixed in place, and may in case oi? a rotating axle be iixed thereto.

The tappct-pins 43 preferably have each a loose antifrictionsleeve 45 mounted thereon, and as these tappets successionally come into contact with the lever 29 or its rear eXtension each of them turns or swings said level' in one direction on its pivotal point, the journal 30, and in doing so forces the rear end of said lever downwardly and its forward end upwardly and baekwardly into the position shown by dot-lines at Fig. 2, and the lever 29, as it swings into such position, will by means of the lilik 4l draw the radius-arln 42 backwardly at its outer end and thereby swing or oscillate the rock-shaft 7 in one direction, the same direction that it is moved by the tappcts on the check-rower line, and thereby give a partial rotation to the seed-cup wheel and movement to the discharging-valve in the seed-tube, the same as is given to said parts by the tappets on the check-rower line. Immediately after the escape of each tappet-pin 43 from the rear extension of the lever 29 the spring 23 not only restores the valve and valveopener in the seed-tube and the pawl which actuates the seed-cup wheel to their normal positions, but also, by means of the arm 42 and link 4l., restores the lever 29 to its normal position, as shown by full lines at Fig. 2, and ready for the action of the next succeeding tappet-pin 43.

The extension 34 of the lever 29 will not interfere with backing the planter, as it will swing upwardly, as shown by dot-lines at Fig. 3,when a tappet-pin 43 eomesin cont-act therewith, and thus permit of said pins passing the lever as the planter-wheel turns backwardly. The driver may with his foot or by other m cans turn the extension 34 upwardly, as shown by full lines at Fig. 3 and dot-lines at Fig. 2, where it will remain, and while in such position the tappetpins 43 will not come in contact therewith, and hence will not operate the drilling mechanism in turning the planter around at the ends of rows, in movingit from place to place, or in moving it over ground where planting is not desired, and while the lever 29 is otherwise in operative position i'or drill-planting.

rlhe tappet-pins 43 are at such short distances apart that they will operate the seedcup' disk much more rapidly than is done by the check-rower line, and hence make the deposits of the single grains of seed at short distances apart, as is usual in drill-planting. The starting and stopping of the intermit tently-rotating seed-cup plates at the passage of each seed-cup beneath the cutoff will, by the slight jars given thereby to the seedcups in contact with the seed in the seedbox, tend to effect a complete settlement of the singlegrain charge in each seed-cup before it passes beneath the cut-oli', and hence produce regu lar dropping of such charges of seed, which is not accomplished by a continuously-rotating seed-cup plate.

The use of the lower valve in drilling, by dropping the single grains from a point near the deposit of the seed in the soil, will secure substantially accurate dropping of the grains at uniform distances apart, which is not done when the grains fall from the. seed-cup disk to the place of deposit and sometimes fall direct, while at other times they strike the sides of the seed-tube duct, and are also affected IOO IIO

more or less in thisrespect by changes in the rate of speed of the planter in operation. If preferred, however, the lower valve may be removed when the planter is used as a drill.

In the use of this planter in check-row planting the seed-cup plates are changed, as described, and the check-rower line used in the ordinary manner, and the drilling attachment can be thrown out of gear to not interfere with check-row planting, as hereinbefore described, by simply turning the extension 34 into the position shown by full lines at Fig. 3. The link 4l may also, if preferred, be disengaged from the radius-arm 42. The lever and link will then remain in position where they can be quickly and readily adj usted for drill-planting.

I do not claim as my invention the adjustable plate 47 as a cover for the opening in the upper end of the seed-tube.

What I claim as new, and desire to secure by Letters Patent, is
