SPECIFIATION forming part of Letters Patent No. 381,073, dated April 10,

To @ZZ whom it may concern,.- I

Beit known that we, AUSTIN S. HoUcK and EDWIN Honomcitizens of the United States,

residing at Bedford, in the county of Taylor' and State of Iowa, have invented certain new and useful Improvements in Corn-Planters, of

which the following is afnll and clear descrip;

tion, reference being had to the accompanying drawings, forming part vof this specication, in which` Y Figurel represents a perspective view of a corn-planter embodying our invention. Fig.-

2 is an enlarged sectional View on the line x x tions of devices, which we, shall'hereinafter of Fig. 1,taken` through one of the seed-boxes. Fig. 3 is .an enlarged sectional view showing the valve in the runners and the manner of connecting the valve-rod with they bell-crank lever on the inner side of the seed-boxes. Figs.

4, 5, and 6 represent details of construction.' Fig. 7 is aside elevation showing the inner side of one of theseed-boxes withthe pitmen, bell-crank lever, 8vo. Y

Our invention yrelates to corn-planters, andit is an improvement on a formerf patent granted to us J une 16, A1885, No. 320,063; and it consists in the constructions and combinafnllydescribe and claim'.

To enableothers skilled in the art to make and use our invention, we will now describe v the same andindicate the manner in which the same is carried out.

In the said drawings, A represents the main .frame of the machine, carrying the usual bearing-wheels, B, seed-boxes C, and such other well-known essential features as go to make up a complete planter.

On the ioor of the seed-box is journaled the usual .rotating dropper plate ordisk, D, having openings or pockets a for the grain, and

peripheral lugs b, beveled on one side and enf t gag'ed by a pawl,wherebysaid diskV is rotated to bring the openings or pockets a into'alignmentwith the discharge-opening c in the bot tom of the seed-box. segmental slotVd, is fitted in the seed-box immediateiyover the amplia-plate the walls 'or said slot converging downwardly, directing the grain to the dropper-plate, andv assists in preventing any clogging or choking of the dropper-plate. Secured to the under surface Application filed December A17,1881'. Serial No. 258,l 66. (Nomodel.)

`discharge end of the slot.

A plate, E, having a I coRN-LANTE-R. 2

the plate. E by aspring-platae, is a bar, v

f, having a curved front end extending into thedischarge end of the slot, so that its under surface will llie on ajlevel with the top-of the dropper-plate. rIhis construction prevents any but the grain in the pockets or openings a from being discharged from the seed-boxes, and also preventsl the clogging or choking ot' thedropf 6oY per-plate vbythe accumulation .of grainj atk thel Passing transversely across the through the seed-boxes is a shaft, F, andon this shaft, adjacent to the inner side oi eachV lseed-box,` is an arm,.G, havingitsouter ends bifurcated or slotted, yas shown at g andjg.'

machine and' The shaft F passes through the center of the, j arm andoscillates said arm, whichisirig`idly viixedtoit in anyzsuitableV manner, and'in the f lower slotted 'portionof the arm one end of a `pitnnan or link, h, is pivotally secured, the o pposite end of the link carrying awrist-pin, 13,

.which passes through a slot, j, in the side of the feed-box, as shown in"'Fig. 4, and carries` on its lower end a gravitating-pawl, H, adapted-y dropper-plate..

. From this description it will beseen that as; l

theshaft F is oscillated ,byv means hereinafter disclosed, .the armsGr, acting upon ,thel link-h,

cause the pawl H to be moved forward and I backward, the said pawl on its forward stroke Y engaging the straight sides of the lugson the dropper-plate to move said. plate, sothat oneofits pockets or openingsis brought'into di'- rect alignment with the underlying dischargef opening to prevent the pawl pushing-the'dropf per-plateso far that its openingor'pocket willv not be directly over the discharge-opening in the bottom of the seed-boze We have placed a stop, k, on the inner side vof the sect1-borg; l and have so. located this stop that it arrests the movement of the pawl and the consequentY rotation of the droppen-plate. the momentoie of the discharge pockets'or lopenings vin said plate is over the discharger iu -the bottom of' the seed-box.

The oscillation of the shaft Fmaybe accomplishedeby any well-known means; butweprc- 1 fer to eect its movement*bythe-methods herein described. In one instancelthismove-v;

mentmay bev obtained bythe rkuolosonther V to engage the lugs on the periphery ofthe Q usual check-wire engaging the slotted arms l on the outer ends of the shaft; or it may be accomplished by a foot-lever or treadle, I, pivoted on the main frame of the machine near the drivers seat. the said lever being connected by a rod, l', with the shaft F. By this latter means the operator is permitted to regulate the dropping of the grain from his position yon the machine whenever he does not 'wish to use the check-wire, or when he wishes to plant closer than the knobs on said wire indicate.

A spring, K, secured at one end to the arm G, has its opposite end fixed to a slotted arm, J, adjustably secured to the side of the seedbox, whereby said arm and its adjuncts are drawn backward into their normal positions as soon as the forward oscillation of the shaft has been completed.

The runners L are secured to the main portion of the machine in any well-known manner, and may be constructed as shown in our said former patent, being .provided with a valve, M, having an upwardly-extending rod, N,which i s connected with one arm,m, of a bellcrank lever, O, pivoted to the side of the seedbox, the other arm, n, of said lever being cut away on its inner side to form the notch 0,which is engaged by the notched end of a rod or bar, P, loosely pivoted in the upper end ofthe oscillating arm G.

It will thus be seen that as the shaft F is osoillated by either of the means before described its movement transmitted through the arm G and rod or bar P forces the arm n of the bell-crank lever O backward, thereby rais ing the arm m of said lever to open the valvein therunner and to permit the escape of the grain in the feed-passage of the latter. As the arm mis raised, its top surface strikes the under sur face of the pivoted rod or pitman P, and raises the notched end of the latter ont of its engagement with arm n. As soon as the arm n is released,the weight of the lower arm, m, and its attachments causes the bell-crank lever to resume its normal position, and permits the valve M to close the feed-passage in the runners. The feed of grain from the runners is thus automatically controlled by the oscillation of the transverse shaft and arm G, the valve in the runners being opened during the period the dropper-plate is being rotated, but closed again by the release of the bell-crank lever before the succeeding pocket of grain is deposited into the feed-passage of the runner.

The seed-boxes herein shown may be provided with the usual guide-pulleys for the check-wire, and the runners, which are placed to one side of the center of the seed-boxes, are provided with curved plates Q, for directing the grain from the box to the runner,and also with any well-known form of shoes R. In addition to these features, the machine may be supplied with theusual lever for elevating the front of the machine to regulate the depth the shoes enter the ground, and such other wellknown accessories as may be found in'a successfully-operating planter.

Having thus described our invention, what we claim as new, and desire to secure by Let.

1. In a corn-planter, the seed-boxes and the transverse shaft passing through said boxes,in combination with the arms G, fixed on said shaft, the pitmen or links pivoted in thelower ends of the arms and provided with wrist pins passing through slots in the boxes,apawl carried by each pin and reciprocating in each box,a stop onthe inside of each box for checking the forward movement of the pawl, and a spring for retracting said pawl, substantially as described.

2. The seed-boxes provided with the rotating dropper-plates and the oscillating shaft, arms, pitmen, and pawls for actuating said plates,'in combination with a plate,E,in each box over the dropper-plate,said plate vE being provided with a slot having downwardly-converging walls for directing the grain to the dropper-plate, and the barf, projecting into the discharge end of the slot, substantially as described.

3. The'main frame, an oscillating shaft,the arms G, the pitmen or links h, the pawls H, and the seed-boxes having rotating dropperplates, in combination with springs connected with said arms G, a foot-lever or treadle pivoted to the main frame, and a rod or bar connecting said lever with the shaft, whereby the latter is oscillated, substantially as described.

4. In a corn-planter, the combination of the seed-boxes having rot-ary dropper-plates, the oscillatingtransverseshaft,the armsGthereon, adjacent to each seedboX, a pitman, P, connected to the upper ends of said arms, a pitman attached to the lower ends of said arms, pawls carried by said lower pitmen and actuating the dropper-plates, the bellcrank levers operated by the upper pitmen, the runners having valves therein, and rods extending from said valves to thelower arms of the bellcrank levers, whereby said valves are operated during the movements of the shaft and dropper-plates, substantially as described.

5. The combination, with the seed boxes, complementary seed-dropping mechanism,and an oscillating shaft for actuating theseeddropping mechanism, of a bell-crank lever on each seed-box connected with the valve in the adjacent runner, and a pitman carried by the shaft and operating the lever to open said valve, said lever having a lower arm adapted to engage the pitman during its upward movement, whereby the upper arm of. the lever is `released and the valve automatically closed, substantially as described.
