CORN-PLANTER.

SPECIFICATION forming part of Reissued Letters Patent No. 10,180, dated August 15, 1&8?.

Original No. 253,530, dated February 14, 1882. Application for reissue filed June 15, 1882.

To all whom it may concern Be it known that I, GEORGE W. BROWN, of Galesburg, in the co'unty of Knox and State of Illinois, have invented a new and useful Improvement -in Corn-Planters, of which the following is a specification, reference being had to the accompanying drawings, which form part of this specification.

My invention relates to that class of cornplanters having a horizontally-rotating seedwheel in each ot' the two hoppers, said seed wheels or disks having an intermittent rotary motion imparted to them by means of a reciprocating har and lever, the reciprocating bar and seed-disks being so constructed and combined that one seed-disk only is given an impulse by each alternate throw of the reciprocating bar, and remains stationary during the alternate throws thereof.

My invention consists, first, in soconstructing and combining a cutoff slide with a horizontally-rotating seed-disk and reciprocating har that at each movement of the reciprocating bar a single seed-cup is discharged, While the seed-disk is given an impulse at each alternate movement of the reciprocating bar only, remaining stationary during the alternate throws thereof; second, in a cut-oli" slide and horizontally-rotanti g seed-disk so constructed and combined that at each impulse given to the seed-disk by the reciprocating bar two seed-cups are brought directly over the place of discharge, only one ot' which is discharged, the remaining cup being discharged by the return movement ot' the reciprocating bar; third, in so constructing and combining a cutoi' slide, horizontally-rotating seed-disk, reciprocating bar, and valve in the seed-tube that while the seed-disk is given an impulse at each alternate throw of the reciprocating bar only, the cut-oli' slide and valve are Vibrated or oscillated simultaneously at each movement or throw ot' the bar, thereby causin g a single seed-cup to be discharged into the seed-tube and a charge of seed to be discharged from the sced-tube into the ground simultaneously at every throw of the reciprocating bar.

In the drawings, Figure l is a perspective view of the one seed-hopper containing my improvements, of which in practice there are two, the same as in an ordinary two-row cornl planter. Fig. 2 is a perspective view with the hopper, seed-disk, and reciprocating bar re,- moved to show the slide. Fig. 3 is a plan ot' the seed-droppen Fig. 4 is a cross-section ot' the same. Fig. 5 is a vertical section ot' the valve in the seed-tube through the line ma,

tions are slightly inclined or beveled atf, which come in contact with the lng G on the bar H, acting as a stop to arrest the rotation of the seed-disk. j

I is a cut-o1`1n slide, situated under the seeddisk O, and moving on the same axis, and is provided with a foot, i, which foot engages with or takes into a slot or ratchet, h, on' the under side of the reciprocating har H, so that the cut-oit' slide I is caused to vibrate or oscillate within the opening J in the plate A by means ofthe reciprocating bar H, and at each throw thereof.

H is a reciprocating bar which extends across the machine, its purpose being to actuate the seed-disk G at either side of the machine, and it may be reciprocated by the hand-lever N or any other suitable means.

K is a pawl so situated and carried ou the reciprocating barH thatwhen the bar is moved in the one direction the pawl K strikes against one of the lugs or projections F, causing a partial rotation of the seed-disk G, but when moved in the opposite direction it passes over the lug vor projection F, immediately in the rear of the one previously acted upon, and then is in position to act upon said lug or projection at the next movement ot' the reciprocating bar H. 1t will be observed that precisely the opposite actiontakes place in the other hopper by reason of the pawl F at each end of the bar H being situated and carried in the same manner, but pointing in opposite directions.

M is avalve situated in the seed-tube O, pivoted at m, and having at its back two projections, m m. In the lower part of the seedtube O is secured a piece, P, which has a vision-wall, p, and two oblique grooves, Q Q', thus forming two channels froln the seed-tube to the ground.

L is a slot or detent in the reciprocating bar H, into which the upper end of the valve engages, giving motion to said valve M at every throw of the reciprocating bar H, which causes the valve M to vibrate in such manner that it alternately opens and closes thegrooves Q Q as the said valve M is vibrated by the reciprocating bar H, which allows a charge of seed to be received and held in the seed-tube, while at the same time a charge of seed is deposited in the ground. J is an opening in the plate A, directly over the seed-tube, and where the cups to be discharged are brought, their discharge into the tube being governed by the movement of seeddisk C and cut-oli' slide I.

The operation is as follows: The reciprocating bar H being thrown to the left, Ythe pawl y K strikes one ofthe projections or lugs F and rotates the seed-disk one-ninth of a revolution-there being nine projections or lugs F, which is the number I prefer-which brings two seed-cups E over the place of discharge, J. This movement of the reciprocating bar H causes the right-hand end of the slot or detent 7L to engage with the fo'ot t' of the cut-off slide I, moving it vto the left, and the right-hand 'end of the slot L to strike the top of the valve M, moving it to the left, while. the lower end of the valve passes to the right, closing the mouth of the groove Q. The movement ofthe seed-disk C begins rst, then the slide I and valve M simultaneously, all finishing their movement at the same instant. The momentum imparted to the seeddisk C bythe reciprocating bar H and pawl K might cause it to rotate beyond the point desired; but the lug G, coming in contact with theinclined or beveled edgefof the projection or lug F, causes it to stop in exactly the proper position. By this action two full seedcups E are brought directly overv the opening -or place of discharge, J, the rear seed-cup discharging into the seed-tube and being held in the groove Q by the valve M, while the forward seed-cup is prevented from discharging by the cutoff' slide I, which acts as a bottom for said seed-cup. At the return-throw of the reciprocating bar H the seed-disk C remains stationary, the pawl K returning to .its original position, the lefthand end of the slots or ratchets 7L and L enga ging respectively the footz' of the cut-offslide I and upper end ofthe valve M, moving them both to the right hand, the lower end of the valve passing to the left, and closing the mouth of the groove Q. rlhis combined action causes the forward seed-cup to discharge the cut-oli' slide I, which acted as its bottom, having been moved to the left in the seed-tube, and held in the groove Q by the valve, while at the same time the charge held by the valve in the groove Q is discharged into the ground, and this action is continued so long as the machine is in operation.

In practice the ordinary caps and cutoffs are used over the seed-disks C, which are not shown in the drawings or referred to. rIwo seed-hoppers are used to each machine, precisely the same inv construction, so that when the movement of the seed-disk causes discharge in the one the movement ot' the slide causes the discharge in the other, and vice versa.

What I claim isl. In combination with a seed-cup disk having an intermittingly-rotating motion in one direction imparted to it bya reciprocating bar, H, which acts upon it by its throw in one direction and allows it to remain at rest while its throw is effected in an opposite direction, a eut-off slide, I, adapted to move with the forward movement of the barH and seed-cup disk and act as a bottom to a seed-cup, and to be removed from beneath said seed-cup by thc backward movement of the bar H to allow the seed to be discharged from said cup.

2. In combination with an intermittinglyrotating seed-cup disk in which two seedcups are brought beneath the cut-oli1 at each movevment of the disk, a sliding bottom adapted to hold the seed in one seed-cup while another discharges its seed, and to be moved from beneath the seed-cup which it closes to allow it to dischargeits contained seedwhile the seedcup disk is at rest.

3. In combination with the intermit-tinglyrotating seed-cup disk U and sliding seed-cup bottom I, the bar H, adapted to give a partial rotation to the disk C by its alternate throws and to move before its action on the slide I at each throw, so as to properly place, retain, and remove said slide in relation to one of the seedcups.

et. In combination with the intermittinglyrotating seed-cup disk G and bar H, which acts upon it at alternate throws ot' the slide, the sliding seed-cup bottom I and valve M, arranged to operate in relation to each other and to the seed-cup disk, substantially as and for the purpose specified.

5. In combination with thesecd-cup disk C and bar H, alternate throws of which act on said slide, a sliding seed-cup bottom located close beneath the seed-cup disk, and a vibrating valve located in the seed-tube,both ot' which are vibrated in one direction at each `throw of the bar H, substantially as and for the purpose specified.
