CH ECK-ROW CORN-PLANTER.

PECIFICATION forming part of Letters Patent No. 472,246, dated April 5, 1892.

Application filed November 30,1891. Serial No. 413,586. (No model.)

To aZZ whom it may concern.-

Be it known that I, JAMES R. AYERS, a citizen of the United States, and a resident of Petersburg, in the county of Dinwiddie and State of Virginia, have invented certain new and useful Improvements in Check-Row Corn- Planters and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

My invention relates to check-row cornplanters, the object being to provide an improved construction of the same, whereby superior advantages. are obtained with respect to simplicity both in construction and operation.

The invention consists in the novel construction and combination of parts hereinafter described and claimed.

In the accompanying drawings, Figure l is a plan view of a corn-planter constructed in accordance with my invention. side elevation of the same. Fig. 3 is a perspective view of the seed-dropping-and marker-actuating devices. Fig. 4 is a perspective View of the seed-dropping spout. Fig. 5 is a detail view of the markers. Fig. 6 is a detail sectional view showing the seed-plate and the lever for clearing cavities of impacted corn.

To enable others skilled in the art to make and use my invention, I will now proceed to describe the same in detail, referring to the said drawings, in which the frame of the machine is shown as being constructed in two sections hinged together. The front section consists of the bars 1 and cross-bars 2, while the rear section consists of bars 3 and cross bar 4.. The said front section carries the seed-boxes 5 5one on each sideand also the furrow-opening plows 6 6, seed-dropping spouts 7 7, and seed-coverers 8 8. These seedboxes may be of any ordinary construction, and the bottom of each is provided with an aperture 9, which registers with the upper end of the seed-spout.

Located in the hoppers and journaled to the bottom thereof is a feed-wheel 10, having its periphery provided with cogs or teeth 12, and also having a series of apertures 13, so

Fig. 2 is a arranged as to successively register with the aperture 9 as the wheel is rotated.

The seed-dropping spouts 7 7consist of inclined spouts secured at their upper ends to the hoppers or the frame, while their lower or delivery ends are in line with the seat on which the person operating the feeding mechanism sits. These spouts are open upon their upper or rear sides, and in each is pivoted about midway of its length a flirt-valve or seed-dropper consisting of a lever 14, having a plate 15 at its lower end, which closes the delivery end of the spout. The upper end of this lever is provided with an angular arm 16, which is adapted to be engaged by the teeth of the feed-wheel as it is rotated, so as I to actuate the said plate 15, thereby uncovering the delivery end of the spout and permit the seed which has been fed from the hopper to be deposited in the furrow formed by the plow.

The reference-numeral 17 denotes the seat for the drop-man or person actuating the seedfeeding mechanism, and which, as before stated, is in line with the delivery end of the spouts 7, so that he can readily see when the said spout reaches the proper point and actuates the said devices to drop and feed the seed. At a point within convenient reach of said operator is a vertical lever 18, the lower end of which is connected with a transverse reciprocating rod 19, extending across the machine. This rod 19 is connected with longitudinal rods or bars 19 by means of pivoted links 20. The forward ends of these bars 19 are provided with pivoted pawls 21, which are adapted to slide over the cogs 12 of the feed-wheels 10 in their forward movement, and to engage therewith on the return movement, which will move each of said wheels the extent of one tooth or cog and cause one of the apertures 13, containing a grain of corn, to register with the aperture 9, and the grain to drop down the spout 7 and be caught by the plate 15 at the delivery end thereof. Upon the next stroke of the rods 19 the feedwheels will be again moved to the extent of a cog or tooth, and the operation will be repeated. At the same time, however, the levers 14- will be actuated by the cogs of the feed-wheel, so that the grain previously deposited in the spouts will be dropped in the IOC furrows and the plate 15 then returned back to its former position to intercept and hold the next grain fed from the hopper until the feedingand dropping mechanism is again actuated. It will be seen that by means of the links 20 each stroke of rod 19 causes two strokes of bars 19.

I have also provided improved marking and pressing devices, which are constructed as follows: As seen in Fig. 2, the driving-wheels 22, which are fixed to the axles 23, journaled in the longitudinal bars of the rear frame-section, are not in line with the seedspouts, and do not therefore press the earth down upon the grain, as in some forms of corn-planters. In the present instance the axles are extended outside of the wheels, and upon the same are mounted collars 2&, provided with three (more or less) radial pressing and marking arms 25 of the same or about the same radius as the wheels, and provided at their outer ends with plates 26. These plates may be rigid, as shown in Fig. 1, or made yielding by intervening springs between the plates and the axle, as shown in Fig. 5, the one or the other style being used as the nature of the ground renders most desirable. The collars 24E fit snugly upon the axles 23, so as to rotate therewith by frictional contact. A collar or hub 24: is mounted upon collar 24, and secured in position by a set-screw 24", and is provided with radially-projecting short arms 27, the outer ends of which are adapted to engage with plates 28, projecting outwardly from short bars 29, pivoted to the longitudinal bars 19, so as to form checks and prevent the said collars and arms 25 from rotating.

The operation of these devices is as follows: As the machine moves forward and the seed feeding and dropping devices are actuated to deposit the seed in the furrows, the plates 28 will be carried forward by the rods 19, so as to clear the ends of the arms 27 and allow the collars to rotate and the arms 25 and their plates to also rotate and press and mark the ground where the seed has been deposited. As the stroke of the rods 19 is quite quick and sudden, the plates 28 on their return movement might strike the arms 27, which move much slower. To prevent this, the bars 29, which carry said plates, are provided with springs 30, which throw the said plates upward as they return out of the path of the arms 25 just released. They will, however,

lie in the path of the next arm 25 as it comes around and, engaging therewith, will stop movement of the collars until the said bars 1S)" are again actuated.

It will thus be seen that an intermittent rotary motion is given to the collars and marking-arms, which must be so timed with respect to the seed-dropping mechanism that the n'larking-arms will suecessively press and mark the earth at the points where the grain is deposited as the machine moves forward. The previous marks made by the marking-arms serve to indicate to the operator when to actuate the seed feeding and dropping devices at the next bout. The collar or hub 24. is adjustable on the collar 24. by means of the set-screw 24), so that the arms 27 may be adjusted with respect to arms 25 as to insure the markers striking the earth at exactly the point where the corn is dropped. Should the corn become impacted in the cavities 13, so that it will not discharge when the said cavities register with the apertures 0, a knocker or lever 31 is provided, the outer end of which is elevated by the teeth of the feedwheel, so that its inner end enters the cavity and forces out the seed.

Having thus described my invention, what I claim is 1. In a check-row corn-planter, the combination, with the driving-wheel and axle and the seed feeding and dropping devices, of the intermittently-rotating markers carried by the axle and means, substantiallyas described, whereby the markers are released by the movement of the seed-dropping devices.

2. In a check-row corn-planter, the combination, with the driving-wheels and axle, of the collar on said axle, the radial markingarms, the adjustable collar or hub, the short radial arms secured thereto, the horizontal bar, the plate adapted to engage with said short arms pivoted thereto, the transverse bar and pivoted connecting-link, and the operating-lever, substantially as described.

3. In a check-row corn-planter, an adj usting device which by its adjustment determines the position of the marker each time the dropping mechanism is actuated as to insure the markers pressing the ground at points to correspond with the dropping of the corn, substantially as described.

l. In a check-row corn-planter, the combination of dropping devices with the intermittent rotating marker and means for releasing the marker at the instant the corn is dropped.

In testimony that I claim the foregoing as my own I h. ve hereunto atfixed my signature in presence of two witnesses.
