EDGAR SHANNON AND ALBERT SHANNON, OF OATAVISSA, MISSOURI.

CORN-PLANTQER.

SPECIFICATION forming part of Letters Patent No. 263,064, dated August 22, 1882.

Application filed March 13, 1882. (No model.)

To all whom 'it may concern:

Be it known that we, EDGAR SHANNON and ALBERT SHANNON, of Oatawissa, in the county of Franklin and State of Missouri, have invented certain new and useful Improvements Figure 1 is a top plan view of our improved corn-planter. Fig. 2 is a bottom plan view. Fig. 3 is a side view. Fig. 41E is a vertical sectional view taken through the shaft or axle. Fig. 5 is a longitudinalvertical sectional view of one of the seed-boxes. Fig. 6 is a detail view, in perspective, of one of the seed-dropping wheels withits planting-tubes.` Fig. 7 is a detail sectional view of one of said plantingtuhes. t i

Corresponding parts in the several figures are denoted by like letters of reference.

'.lhis invention relates to corn-planters; and it consists in certain improvements in the construction of the same, which will be hereinafter fully described, and particularly pointed out in the claims.

In the drawings hereto annexed, A represents the frame of the planter, the longitudinal beams of which, B, 'havebearings for the axle C, upon the spindles of which the wheels D E are mounted loosely.-

Upon the hub F of wheel D is mounted a clutch-collar, G, sliding longitudinally and pre vented from turning by a key, H. The collar G is capable of engaging a clutch, secured firmly upon the axle, which may thus be made to revolve, as will be hereinafter described.

Mounted in the frame A, in rear of axle C, is a shaft, I, carrying a pinion, J, engaging a gear-wheel, K, of three times its size, mounted upon the axle, so that shaft I shall make three revolutions to each one of the axle. At its ends the shaft I carries crank-wheels L, which are connected by pitmen M with the seedslides N, which reciprocate longitudinally in the seed-boxes. rlhe latter, whichiare mounted in the usual manner upon frame A, consist of suitably-constructed hoppers O, having double bottoms, between which the seed-slides are arranged, as shown.

VAbove the seed-slides are placed the cut offs P, which consist of plates having slots Q to admit the seed to the openings or seed-cups in the slides and forced in a forward direction by suitably-arranged springs It. 'Ihe slides N have upward-projecting pins S, which workin the slots Q, and which, as the slides move inV a rearward direction, strike the rear ends of the slots and move the cut-os slightly back against the tension of the springs. By this construction the seedcorn is prevented from being bruised or otherwise injured by coming between the seed-cups and the cut-offs.

The bottoms T of the seed-boxes have openings U, which receive the seed-corn from the cups or openings in the slides, which on their rearward movement conveyit to said openings-` U. Curved tubes Vreceive the seed-corn from the openingsUand convey it to the seed-wheels, the construction of which we shall now proceed to describe.

W are the seed wheels or disks, which are.v

mounted upon the axle adjoining the transport,- ing-wheels.` The disks W are provided upon their inner sides with ilanged rims X, forming annular grooves or gutters,into which the seed conveyed through the curved tubesV from the Vslots D', in which small plates or cut-offs E are pivoted, their inner ends being capable of extending into said slts, so as to cover the discharge ends of the curved tubes B. The outer ends of the cut-ottl plates E have slots FtOl receive pins G projecting from the hinged lids or covers A. It will be seen that when the foo upper ends of said lids are pressed against the tension of their respective springs, so as to open the seed-depositing tubes, the cut-oft' plates E' are thrown into the slots D', so as to close the discharge ends of the curved tubes B'. The lids A' are operated so as to effect this result by means of disks H', pivoted or journaled to brackets I' upon the under side of theseeder-frame. As the seed-wheels revolve with the axle of the machine, the lids A' of the dropping-tubes will in passing come in contact with the edges of the disks H', and thus be pressed open. By this construction and method of operation resistance by friction is almost completely avoided, and the seed is deposited regularly at proper intervals.

Secured to the, axle G, or forming partof one of the seed-wheels W, as shown in the drawings, Fig. 2, is a clutch, J', adapted to engage the clutch-collar G upon the hub of wheel D. Said clutehcollar is journaled in a frame, K', having arms L', to the ends of which are attached rods M', sliding in slots N' in the longitudinal frame-beams B, so that the said frame mayhave a transverse sliding motion, by which it causes the clutch G to be engaged with or disengaged from the clutch J', as the case may be. The inner ends of the rods M' have slots O' to receive the diagonal bent ends of a longitudinally-slidin g bar, P', for which bearings are provided in brackets Q', secured to the frame. It will be seen that by operating the bar P', which is done by means of a suitablyarranged lever, R', the frame K' may be slid in either direction, thus coupling or uncoupling the clutches G J, and thus connecting or disconnecting the operating mechanism of the machine with the driving and transporting wheel D, as may be desired.

S' is a lever, pivoted loosely upon the axle, and having a spring-catch, T', capable of engaging a cog-wheel or pinion, U', mounted securely upon the axle. When the latter is disconnected from the driving-wheel D it may be turned by means of the said lever so as to bring two of the dropping-tubes down to the ground in proper position for planting at the starting-point.

V' are the furrow-openers, which are hinged by the front ends of their beams W' to the front end of the frame A. The furrow-openers are used in sets of two, suitably constructed and connected by a cross-brace, X'.

Yl is a shaft mounted transversely in the frame A, and provided at its ends with cranks Z', connected to the furrow-openers by slotted plates A2, around which springs B2 are coiled, which will give when necessary, and thus permit the furrow-openers to pass over rocks, stumps, and other obstructions without injury.

C2 is a lever secured upon the shaft Y', and provided with a spring-catch, D2, which engages the teeth E2 in a segmental ratchetplate, F2, secured to the frame. By this mechanism the furrow-openers may be raised from the ground and retained in any position to which they may be adjusted.

A shaft, G2, journaled longitudinally upon the frame near its front end, is provided with a handle, H2, and with an arm, l2, having an extension-slide, J 2, serving as a gage, and which, by means of the handle, maybe turned so as to project on either side of the frame.

The central longitudinal frame-beam, K2, carries the driver's seat L2, which is so arranged as to be within convenient reach of the several operating-levers.

In operation the seed passes from the hoppers through the curved tubes Vto the flanged rims or gutters'X of the seed-wheels. As the latter revolve the seed passes into the curved tubes B'. When the seed-tubes Y reach the disks H' the lids A' are opened and the cutoffs E' closed. When the disks H' are passed the lids A' are again closed and thefcut-offs opened, thus permitting the seed to pass into the seeding-tubes. When the same seedingtubes again reach the disks H' and the operation is repeated the seed is deposited in the ground by the seeding-tube, which, as soon as the disk H' is passed, receives a new supply from the curved tube B', by which it is connected with the seed-wheel.

Having thus described our invention, we claim and desire to secure by Letters Patent of the United States- 1. The combination of the hoppers 0, the seed-slides N, having pins S, the cut-off plates P, having slots Q, and the springs B, arranged to force the said cut-off plates in a forward direction, as described, for the purpose set forth.
