IMPROVEMENT IN CORN-PLANTERS.
Specification forming part of Letters Patent No. 36,569, dated September 30, 1862.
To all whom it may concern:
Be it known that we, H. B. LANSING and H. W. GRENELL, of the town of Hudson and State of Michigan, have invented certain new and useful Improvements in Corn-Planters, and we hereby declare that the following is a true and exact description of the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon.
The design of our machine is to plant two rows of corn at a time, also to mark the ground, open the earth for the reception of the seed, then cover the seed, and, lastly, stamp the earth on it, as is usually done with a hoe. The ground is marked one way by following back the same track alternately with one wheel, and in the other Way by the markers or arms e c e, which mark at right angles to the direction you are planting.
In the annexed drawings, made a part of this specification, Figure 2 represents a vertical section of our machine; and Figs. l and 3, plan views of the same, cut off near the center.
One section ofthe machine is not exhibited in the drawings, but is to be madein all respects like the section described, with the exception that the rods bearing the markers e c c are inserted in the axle, the axle at that vend not being furnished with a collar.
In Fig. 3; the vletter A represents the axle, and B one ofthe wheels of the machine. The axle is supported :near its end by boxes in which it can revolve. On the inner edge of the hub B teeth are cut, having sufficient space between them to receive corresponding teeth on the collar C. Between the shoulder E and the collar C a grooveis made to receive the forked lever D, which at its opposite end passes through the rod F and the spring L. The rod F runs at a right angle with forked lever D, is hinged at the support g, and extends to the cross-bar a. Parallel with rod F is the rod h, which is hinged at its point of junction with a h, passes through the support l, and has a lateral motion playing on the pin that attaches it to l. The rod h curves downward near the end, as exhibited in the drawings, and has a slot init, through which a bolt passes to connect it with the lever O. This lever is jointed at the point r, the upper end of the lever being designated by the letter K and the lower end by the letter O. The joint r is so constructed that K may have either a forward or sidewise motion. The bolt that passes through the slot in h beingl secured to the lower part of 0, by moving K to the right the head of the bolt presses against h, which operates on the cross-bar a, and this, acting on rod F, draws the collar C out of its gearing with the wheel B', thus enabling wheel B 'to move Ywithout revolving the axle A.
R is a treadle in front of the driver-s seat, a
connected with the arm I?, and that to the rod q,which at one end is supported by the pendant (marked T) placed under the platform upon which the driver rests his feet, and at the other end g plays in the staple T. At the end of the rod q is the arm u, connected by a hook and eye to the bifurcated lever W, the bifurcations having their fulcrums at c c. To the opposite end of W is attached the tube d, intended to convey the seed to earth. The tube d can be raised or lowered at pleasure by means of the treadle It. The tube d is scalloped at the lower end, the`front edge being made to penetrate some distance into the soil to open it for the reception of the seed,while the hinder edge goes into the ground only sufficiently far to secure earth for covering the hill of corn,which is effected by the progressive motion of d at the moment the seed reaches the opening made to receive it. The instant the corn is covered the stamper Q, descends and presses the earth on the hill.
On the bottom of the platform X are two slides, m and n. Half of m is made to slide on platform X. The remaining half is elevated above the surface of platform X and curved first to the right and then downward, so as to be within the reach of teeth in the cam-wheel M. This cam has three teeth, which, as the axle revolves, press successively against the shank on m and forces the seed-slide H back until the opening in it gets opposite to the mouth of the tube d, when the tooth escapes from the shank, and slide H is driven back by the curved spring r.
The slide fn, has attached to it the branch y, which diverges from it at right angles near its center, passes under slide m, and then runs parallel with m until it reaches a point immediately above the tube d, Midway of slide a is a spur, descending suciently far to be within reach of the teeth on the cam M2. Through a hole in the end of slide n,' next to the tube d, a small cord is passed, and from thence over the pulley t through the stanchion k, then into an eye at the top of the tube d and fastened to the rod ot' the stamper Q. The spur on n,when caught by the tooth of cam M2, forces u forward, and when the tooth escapes from the spur u is brought back bythe weight ofthe stamper Q. By this arrangement the office of the stamper is performed the moment the corn is dropped and covered by the tube d.
a is the bar that connects F and h, by the operation of which G is thrown out of gear with B.
J is the ratchet-wheel, the object ot which is, when taken with its connections, to shorten the distance between the hills. This is done by means of the twofold motion of K, as above described:'rst, by moving the lever K to the right to disengage the collar C from its gearing with B', and, secondly, by moving` thelever K forward and throwing the axle in advance by means of the ratchet-wheel, and thus brin ging the next marker in order nearer to the mark made by the one which preceded it. L is the spring to force back the lever D.
Having thus described our invention, what we claim, and desire to secure by Letters Patent, is-
l. The markers e e e at one end of the axle, inserted into the collar C and at the other end into the axle A, for the purpose herein set forth.
2. The tube d, in combination with the stamper Q, operated in the manner and for the purpose herein described.
3. The jointed lever K O, in connection with the ratchet-wheel J and the toothed collar C, arranged in the manner and for the purpose herein set forth.
In witness that we claim the foregoing we have hereunto set our hands in the presence of two witnesses. V
