SPECIFICATION forming part of Letters Patent No. 274,065, dated March 13, 1883.

Application filed August 17, 1882.

To all whom it may concern:

Be it known that I,`JOHN S.WARD, of Eureka, in the county of Woodford and State of Illinois, have invented certain new and useful Improvements in Corn Planters; and `I do hereby declare that the following is a full, clear, and exact description of theinvention, 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, and in which- Figure 1 is `a plan view, with the wheels partly broken away, of my improved cornplanter.` Fig. 2 is a vertical transverse sec-A tion. Fig. 3 is a longitudinal vertical section. Fig. 4 is an end elevation thereof. Fig. 5 is a detailed plan view of one of the markers; and Fig. 6 is a plan view of one of the wheels, showing the cogged-rim attachment for working in slippery soil.

Similar letters of reference indicate corresponding parts in all the figures.

My invention relates to improvements in corn-planters, having for its object to put into and out of operation the markers, to effect their adjustment, to enable them to penetrate the ground a greater or less depth, to be folded to clear an obstruction, fence, post, stump, 8vo., and to be locked as against un-` gearing the machine, to enable the simultaneous operation of the markers of the seed-slide, and to facilitate the adjustment of the han'dwheel, which controls mostly the aforesaid op-` eration' of parts; `and it consists in the combination and arrangement of parts, substantially as hereinafter more fully set forth and claimed.

In the accompanying drawings, the letter A indicates the frame, having a transverse opening through its middle, in which turns the (No model.)

tion B formsa double crank, b', and its inner hollow end is provided with a pulley, b, fastened upon it. `Two pulleys-one larger, b3, and one smaller, i12-are fastened upon the axlesection B2, inside its bearing. Upon braces c, firmly secured in an upright position upon the frame, are twolevers, D and D', pivoted, the lower bifurcated ends of which-ride astride the pulleys b3 and b, and are connected by an arm, E, hinged tolever D below and to lever D' above its fulcrum, so that by moving the upper end of lever D in either direction the lower ends of it and lever D will either be brought nearer'together orfarther apart, which motion is imparted tothe axle-sections, the v sections sliding together when the upper end of D is Inoved outward, and vice versa. Upon the upper endof leverD is pivoted a handwheel, F, having a smaller flanged portion, over which a sprocket-chain, H, passes, which connects with and operates the pulley b2, and

through it the shaft, revolving the shaft inde-` K is a lever pivoted at the rear upon the frame at 7c, and having a sideward-projec'ting spring, k', the outer end of which is clasped by the slotted upturned end of projection i', and provided upon its upper surface with an upward-projecting lug, 7a2. As the plate t' moves forward and backward, operated by crank b', the curved lip i2 will engage projection k2 alternately upon either side, and the tension of spring k', which is produced by the slotted end of projection i', will force the lever from one side to another when the lip i2 passes projection k2, releasing it. It will be seen that when plate i slides forward the spring will force the lever in toward the center of the machine, and when sliding rearward it will throw it outward, the lip i2 and lug k2 holding it till it springs with a sudden motion, and

the seed-slides, which are connected bysuita- 'ble means to the end of the lever, will be operated by this motion.

The markers L L are attached to the hubs of the wheels C, and consist of two arms, L Z2, projecting from a sleeve, Z, turning upon the hub of the wheel. To the ends of these arms are hinged two hook-shaped arms, Z3 and Z4, the outerV convex edges of which serve to mark and open the hills in which the corn is to be dropped. These arms may be extended or folded by means of elbow-levers m m2, pivoted upon arms ly l2, and connected with arms L3 l* by means of hinged arms m m', which, with levers fm fm, form toggle-levers. The inner arms, m2, of the elbow-levers project into and are operated by slotted projections m3 upon the inward bent ends of yokes M, which are fastened upon the ends of the shaft, and are provided upon the inward bent ends with spring-pawls u, which are adapted to engage the teeth of a ratchet-Wheel, C', fastened upon one of the wheels (l. It will now be seen that by drawing the ends of the axle-sections together the yokes will act upon the elbowarms m2, extending the arms, and at the same time the spring-pawls will 'engage the teeth lof the ratchet-wheel, revolving the markers,

and that the markers will be folded and pawls disengaged when the axle-sections are pushed apart, throwing the whole mechanism out of action.

To secure the drive-wheel from slipping, it maybe provided with a detachable cogged rim, O2, the inside of which is provided with a fiange, which is slipped in under the rim ofthe wheel C. The rim is secured to the wheel by means of fasteningplates 0,which projectfrom the rim of the ratchet-wheel and clamp crossbars d, extending across the space Within the rim and fastened to the inside of the latter. The fasteningplates c' are clamped to the spokes of wheel G by clamps c, so that, if desired, the rim and ratchet-wheel may be made to revolve with the wheel C, or, by unfastenin g clamps c, they may revolve independently of wheel O.

In light ground, where the cogged rim is not necessary, it may be detached by unfastening clamps c. l

Having thus described my invention, I claim and desire to secure by Letters Patent of the United Statesv l. In a corn-planter, the combination of the sleeve or collar l, adapted to turn on the wheel hub or spindle, and having arms l l2, hookshaped markers Z3 l, hinged to the ends of said arms, yoke M, secured to and turning with the end of the axle, having slottedprojections m3, and spring-pawls n, adapted to engage a ratchet-rim upon the wheel and toggle-levers m 'm2 m', as and for the purpose set forth.

2. The combination, in acorn-planter,of the axle B, consisting of sections B and B2, sliding into and turning with each other, provided with the folding markers upon their outer ends and with pulleys b4 and b3 upon their inner portions, with the levers Dl and D, straddling the pulleys, with their lower bifurcated ends pivoted upon the frame, and connected to each other by arm E, hinged to them respectively above and below their fulcrum, as and for the purpose shown and setforth.

3. In a corn-planter, the combination of the folding markers L L, turning on the hubs of the wheels and connected to the shaft, the driving-wheels C, detachable cogged rim C2, the sectional shaft B, and the bifurcated levers engaging with pulleys on the sections of the shaft, as and for the purpose shown and set forth.

4. ln a corn-planter, the combination of the sliding plate t', operated by the crank-shaft b', and having sideward projection i', slotted at its outer upturned end, and curved lipt'z, with lever K, pivoted at k,having springlc, projecting into the slotted projection i', and lug 7:2, operating the seed-slides, as and for the purpose shown and set forth.

5. In a corn-planter, the combination of the sectional axle B, double crank b, sliding plate i, having slotted downward projection I, slotted projection i', and curved lip 2, and seedslide-operating lever K, having spring k and lug k2, and pivoted at k, as and for the purpose shown and setforth.

6.- The herein-described corn-planter, consistin g of theframe, the sectional axle capable of lateral extension and contraction, a double crank, the folding markers, the wheels having a ratchet-wheel and a detachable cogged rim, the hand-levers capable'of being rocked simultaneously in'opposite directions, and the seedslide-operatin g device, substantially as and for the purpose shown and set forth.

In testimony that I claim the foregoing as my own I have hereunto affixed my signature in presence of two witnesses. y

JOHN SWAYZE WARD.
