IMPROVEMENT IN CORN-PLANT ERS.

Specification forming part of Letters Patent No. 180,702, dated August 8, 1876 application filed August 21,1874.

To all whom it may concern:

Be it known that I, LYMAN J. GoRBrN, of Winnebago, in the county of Winnebago and State of Illinois, have invented a new and useful Improvement in Corn-Planters; and I do hereby declare that the following is a full and exact description of the same, reference being had to the accompanying drawings and to the letters of referencemarked thereon.

, Figure 1 is a perspective view of my improved corn-planter. Fig. 2 is a longitudinal section of the forward part of the machine,

. showing the seed-box,- the rotating bills, seedtube, and runner in section; and Fig. 3 is a perspective view of one of the jaws for picking upthe corn, showing the cheek-pieces, which, with portions of the jaw, form the pocket for retaining the seed until the same is deposited in the seed-tube.

Similar letters of reference denote corresponding parts in all the figures. Z The invention has for its object the improvement of that class of corn-planters on which a patent was granted to me January 13, 187 1, No. 146,321; and consists in an improved construction of the jaws or bills by which the corn is picked up, one kernel to each grasp of the jaw, and carried until released and 'deposited within the seed-tube, as was fully described in my former patent, above mentioned; but in the said patent the improvement made by the addition of side or cheek pieces, by which a pocket is formed, was not shown, explained, or claimed, but is shown in Fig. 3 in this application. This feature will be hereinafter explained. It further consists in the construction and arrangement of the wheel and runner-frames, whereby the depth of the furrow may be gaged without interfering with the dropping or picking-up devices, all of which will be hereinafter explained.

In the drawings, A represents the two side beams of the frame, resting upon the drivingaxle at the rear end, and hinged to the crossbar 0 at the forward end, and upon which are mounted the seed-boxes and the seed-distribu- 'ting wheels. A A and A are the rear,

front, and center cross-bars, these composing the main frame of the machine. B B represent the driving and carrying wheels, the one B being mounted loosely on the axle, for facilitating the turning of the machine, while the one B is keyed or otherwise secured to the said axle for drivingthe pulley thereon.

The side beams A extend forward of the cross-bar A and are hinged at their forward ends to the cross-bar O, and to which,also, the forward ends of the runners or furrow-openers are secured, the rear ends of the said runners being connected together by a wider crosse bar, 0 located directly underneath the seedboxes, which, in connection with the runners, form the forward or runner frame.

b b are diagonal braces, secured at their forward ends to the bar 0, at their longitudinal centers with bar 0 and are at their converging or rear ends united together by the crossbar b. To this bar b is hinged, by an eyebolt connection, an, upright rod, 0, having perforations at its upper end for the purpose of making a vertically-adjustable connection with the elbow-lifting lever D. This lever D is, at the elbow joint, pivoted to circular-shaped braces, running from the seat-plank to the forward vertical post a and by means of which, in connection with the lever-locking dog on the top of said seat-plank, the runners may beheld in any desired position vertically within the scope or throw of the said raising-lever, and thus enabling the driver at his will to raise the runners sufficiently high to clear the ground when turning the team around, or when transporting the machine from field to field, or from one part of the field to another part of the same. I

About midway of the length of the center cross-bar A and the rear cross-bar A, upright standards a a are secured, upon which is mounted the seat-plank, having the drivers seat thereon. Near the forward end of the said seat-plank a slot is made, and within the same,'through which passes the lifting-lever D, within reach of the driver, by which, from his seat, he can raise and lower the runnerframe, as may be desired. E are seed-boxes,

mounted upon the beams A, and at ends of the bar A Within these seed-boxes, and at their rear ends,- are transverse PQIIUtlOII-PIGGGS ductor-tube in the heel end of the runner. E is a shaft, lying parallel with and above the 'bar A and mounted in hearings in the seatboxes. This shaft extends intothe seed-boxes to about their centers, and upon the ends are mounted disks E having, portions cut away in the circumference, so as to form arms or or spokes, upon the ends of which are placedspring-jaws 6 e It is obvious that these disks may be made Without cutting away the portions between the arms, and, if desired, the said disks may be full to the extreme periphery, or in any manner so that the operation of the springjaws may not be-interfered with.

To the upper part of the jaws, designated 0 are attached lips or cheek-pieces e The said cheek-pieces may, however, be attached to the under portion of the jaw, and not depart from the spirit of the invention. As these cheekpieces perform an important mission in the picking up and retaining the seed until the time for depositing the same within the receptacle from which the seed is carried to the ground and discharged within the earth, they will now bemore fully described.

In my former patent, before mentioned, these cheek-pieceswere not shown, (ears for forming the hinges only being used,) and in the practical use it was found that the kernel of corn, after having been caught in the hills, and, W'h'il'erpassin'gthrough the mass of grain, was extremely liable to become displaced lat erally, as it"will be observed the kernel is caught when the bill first enters the seed, and must'b'e carried through the mass in the line of the'revolution of the jaws; hence necessitating the protection afforded by the said cheek-pieces, and by means of which a'pocket is formed when thejaws :are open,but none when the jawsare empty and a closed. With these cheek-pieces the seed canonly be discharged from the mouthof the jaws, andlat era'l displacement prevented, and the correct and timely delivery of the grain assured. The upper portion of the'jaw 6 also extends back 'a't'an angle of about torty-five'degrees to the face extension, and" to' the heel end of the same'is' placed as'prin'g, to hold the forward ends of the jaws together.

It will'be seen'that, by this arrangement of jaws above described, asithe diskor spider E revolves, and the rear end of the portionof the jaw e comes'incontact with the's'eed in the box, the jaw, by this rear extension striking'o'r pressing a gainst'the seed, will'cause the pocketed mouth to open and receive a single grain of corn, and the spring'will hold the same, by the closing of the said mouth, until the funnel or place of deposit is reached, when the tripper, for that purpose provided, will, by pressing the extension.- piece, cause the mouth to open and discharge the seed, after which the spring acts upon the jaw, causing it to close until again opened by the rotation or movement before set forth.

To the bar which supports the rear end of the runner is secured a conductor or tube, F, which extends up and around the funnel in the seed-box, also down through the heel end of the shoe, for conducting the grain to the ground.

G is a slide or dropper, which is connected to the bar 0 by loops or staples, und'er'which it slides.

The slide is operated by means of two levers pivoted to it, and passing up through two planks connected to the frame for holding the levers in place,and between these two-levers the operators seat is located. The operator is enabled by these levers to plant any number of kernels of corn in a hill, by operating the valve at one or more revolutions of the disks or spiders. Or by removing the valve the corn may be dropped into the seed-tube directly as received from each pocketed mouth of the picker or jaws. The slide may beoperated automatically by the spider or pickershaft, if desired.

The wheel B" is keyed to the axle, and upon the axle; is also keyed a band-wheel or pulley,

H, from which motion is communicated to the second band-wheel or pulley H feathered upon theshaft E which drives the-pickerwheels.

The band-wheel H is provided with aclutch having lugs or teeth on. its side face, which mesh into corresponding indents made in-a collar, 71., which is keyed to the shaft E, the two being held in mesh by spring d, and held out of mesh by means of a lever, H connected with the band-wheel H through a grooved collar formed on said wheel.

The lever H is pivotedito the frame, and extends back to within reach of the drivers foot, so that he is enabled to throw the-shaft out of gear from-the driving-wheel, and thus control the movements of the picker-wheels E.

I is the tongue connected to the forward cross-bar G of the runner-frame, and which extends back and is secured between two upright lugs or cars mounted on the rearbar of the runner-frame. These lugs or cars are perforated, and by means of a pin passing through the lugs, and through a perforation in the rear end ofthe tongue, the said tongue may be vertically adjusted, as desired.

Under the lower face of the rear frame-bar A and mountedon brackets secured thereto,

are two arms, one at each end of said bar, and connected thereto are scrapers K, by means of which the driver may clean the rimof the carrying-wheels when desired.
