CORN-PLANTER CHECK-ROWER.

SPECIFICATION fanning part of Letters Patent No. 315,220, dated April 7, 1885.

Application filed- February 9, 1883. (Modem Be it known that We, ALDEN BARNES and MONROE BARNES, citizens of the United States, residing atBloomington, in the county of Mc Lean and State of Illinois, have invented certainnew and useful Improvements in Corn- Planter Gheck-Rowers; and we do hereby declare the following to be a full,clear, andexact description of 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 accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

This invention relates to corn-planter checkrowers of that class in which a tappet-wire stretched over the ground to be planted is used as a means for actuating the seed-slides through the instrumentality of a forked lever with which the tappets on the wire come in contact; and the invention relates especially to that subdivision of this class of check-rowers in which the forked lever swings in a horizontal plane. The invention consists, first, in improved 5 means of transmitting motion from the forked lever to the seed-slides of the planter; second, in a novel manner of arresting the motion of the drive-wheel; third, in a new-combination of the guide pulleys for the tappet wire;

fourth, in a novel means for doffingor releasing the "wire from thecheck-rower; and, further, in constructions and combinations here-' inafter described. 7 v

In the accompanying drawings, which illustrate our invention,and in which the similar letters used as marks of reference apply to the like parts III all of the figures Figure l is atop plan of the check-row device. and the forward part of an ordinary corn-planter on' which it is located for operation. Fig; '2 is an enlarged top plan of part of the check-rower. Fig. 3is aside elevation. Fig. at is a rear elevation. Fig. 5 is a plan of the crank-bar for operating the swinging pu1leys. Fig. 6 is a side elevation of one of the links connecting the forked levers with the pawls. Fig. 7 is a side elevation of the drive-pinionand its actuating-pawls.

. Referring to the drawings by letters, A represents the forward part of an ordinary cornplanter, and B the sliding bar, which connects and moves the seed slides in any ordinary manner.

O is the ordinary bar which carries the check-row devices. The bar 0 may be fixed to the seed-boxes of the planter, as shown, or otherwise, as required.

To each end of the bar 0 a plate, D, is fixed, each of which carry similar devices, only one set of which need be described here- 1n.

E is an elbow-shaped forked lever, pivotally connected at its bend b to the plate D or the bar G, as may be desired, so that it may swing in ahorizontal plane in an ordinary manner.

F F are grooved guide-pulleys journaled on is planting, they rotate in or about in hori zontal planes, and while in said normal posi tions are located so. that the flanges f of the pulleys F F project beyond the cylindrical part of the pulleys H H, as shown by full lines at Fig; A, and thereby retain the tappet-, wire between the pulleysH H and the pul leys F F, as shown by the full lines at same figure. The pulleys H H are plain cylinders with a flange,c', on the upper end of each, which flange may be dispensed with. The levers I I are journaled at z" 1', respectively, to standards J J, which project upwardly from the outer ends of the plate D. The inner end of each lever I I has a slot, i,which receive, respectively,the crank ends is of a rockshaft, K. The inner ends of the levels I I are shown as-bent downward somewhat, in order that the rock-shaft may be located beneath the bar 0. These levers may be used straight by locating the shaft Kabovethe bar 0. I v

To one of the cranks k, preferably the one in the rear as relates to the planter, an arm, is fixed, from which a cord, 1", or any other suitable device, extends to within reach of the driver in his seat on the planter, and by means of which, when the planter reaches the ends of the rows, he may turn the shaft K, so that the cranks It will swing thelevers I I, as shown by dotted lines at Fig. 4, and thereby releases the tappet-wire, so that it will fall clear of the planter, which may then be turned round to commence the next bout without the driver dismounting to remove said wire. In coinmencing the new bout the driver places the tappet-wire to the pulleys F F, and then turns the rock-shaft K to swing the levers and to bring the pulleys H H into position to retain the wire, as hereinbefore described.

L is a drive-pinion journaled on a stud, Z, which projects from the bar D, and provided on its upper side with aseries of ratchet-teeth or lugs, Z. Each tooth Z has a vertical side, Z, and a sloping top side, Z.

M M are'pawls, each loosely fitted at one end on the stud Z, so that it may swing or oscillate horizontally thereon, and also so that their outer parts may rise slightly to pass over the teeth Z. A link, N, connects one pawl M with the inner end of the forked lever, which is at one end of the bar 0, and a similar link N connects the other pawl M with the forked lever at the other end of the bar 0, as shown at Fig.

V in gear with the pinion L.

Q is a link connecting a crank-pin, 19, on the pinion 1? with the ordinary lever B, which lever extends downward and hasa pin, 1, on its lower end that rests in a slotted standard, 7", which is connected with the bar B.

As the planter moves forward in operation each tappet gswings the outer end of the forked lever rearward in the direction of the arrow shown at Fig. 2, and the spring 8 returns said lever to its normal position and ready for the action of the next tappet in the ordinary manner. As'the outer end of the forked lever swings rearward its inner end, by means of the link N, connected therewith, will swing the pawl M,connected to said link, and the pawl M, engaging with the vert-ical side Z of a ratchettooth, Z, will give a partial rotation to the drive-pinion L, as shown by dotted lines at Fig. 2. The movement of the pinion L last described is arrested at the proper time by means of the detent a coming in contact with one of the cogs of said pinion, as shown by dotted lines at same figure. Each movement of the pinion L as last described gives a halfrotation to the pinion P, and thereby through the link Q and lever B a throw to the bar B and seed-slides of the planter. Each movement of the pinion P is terminated with the crank-pin p on its dead-center, thereby forming a lock in the ordinary manner to pre vent accidental movement of the seed-slides. WVhen the spring 8 returns the forked lever to its normal position, the pawl M will be swung backward thereby, and will slide up the sloping side of one of the ratchet-teeth Z, and falling behind said tooth will be ready for action on its vertical side at the next movement of the forked lever. WVhen the forked lever at one side of the planter and its connected link N and pawl M are moving the pinion L, the forked lever at the other side of the planter and its connected link N and pawl M will remainstationary, thus saving the useless and, in some respects, injurious movements of these parts when not required.

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

1. Th'e combinatiomwith a check-row wire and with forked levers adapted to be oscillated thereby, of push bars or rods connected with said levers and a central revolving plate or wheel connected with the seed-slide, and provided with a series of projections whereby an intermittent rotary motion is given to the central wheel by either rod, substantially as and for the purpose specified.
