JAMES DROMMOND SOHOFVIELD, OF DALLAS, TEXAS, ASSIGNOR OF TWO- THIRDS TO C. W. PARKER AND PAUL FURST, OF SAME PLACE.

CORN AND COTTON PLANTER.

SPECIFICATION forming part of Letters Patent No. 509,950, dated December 5, 1893.

Application filed July 7,1893. Serial No.4:79,836. (No model.)

To a/ZZ whom it may concern:

Be it known that I, J AMES DEoMMoNDSoHo- FIELD, a citizen of the United States, residing at Dallas, in the county of Dallas and State of Texas, have invented a new and useful Corn and Cotton Planter, of which the following is a specification.

My invention relates to improvements in planters; and the objects in view are to provlde a planter of cheap and simple construction embodying therein improved mechanism for transmitting motion from the drive-wheel to the seed-disk; to so construct said mechanism as to operate only when the planter is being advanced and to remain inoperative when being drawn backward; to provide for a change of speed for the seed-disk so as to plant close together or far apart as may be desired; and to provide a new and improved hood or protector for the gear connection between the drive-wheel and the power-transmitting mechanism, whichllood may be readily cast and will preserve the mechanism at this point against the deleterious actions of dust. and

. other gritty matter that would otherwise iind its way therein.

Various other objects and advantages of the invention will appear in the following description and the novel features thereof will be particularly pointed out in the claims.V

Referring to the drawings:-Fig11re 1 is a perspective View of a planter embodying my invention. Fig. 2 is a transverse sectional view taken vertically through the ground Wheel, the axle, and adjacent parts. Fig. 3 is a vertical longitudinal sectional view through the hopper and the power-transmitting gears and shaft. Fig. 4 is a detail in perspective of the adjustable journal frame. Fig. 5 is a detail in perspective of the cone gear head. Fig. 6 is a detail perspective of the cotton disk, the same being inverted. Fig. 7 is a partial plan and horizontal section of the ground-wheel and its housing. Fig. 8 is an enlarged transverse section through the hopper. Fig. 9 is a plan of the base ring. Fig.

l is a perspective view of the sliding cut-olf. Like numerals of reference indicate like parts in all the iigures of the drawings.

The frame of the machine comprises in this instance opposite beams 1, whose front ends are downwardly curved and provided with bearings 2, for the reception of au axle 3 upon which is mounted a ground-wheel 4, provided at one side with an elongated hub 5, that extends to the inner side of the adjacent beam, and at its opposite side is provided with a toothed hub 6. Between this latter side'of the wheel and the remaining beam there is interposed a cylindrical hood, the samevbeing preferably formed of cast-metal and having its innereud bearing against the face of the hub 6. This hood is provided in its outer closed end with an axial bearing 9 extending at each side of the outer end of the hood and therefore some distance in the same. The elongated hub occupies in conjunction with the wheel and the toothed hub about one-half of the aXle,the remaining half being occupied by the hood. The axle may be secured in position in any proper manner, and in this instance is secured by means of a washer and split-pin 11. The hood is provided at one side in its cylindrical wall with a slot 12, the same being adapted to be partially closed through the medium of a pivoted dust-cap o1' plate 13. The rearends of the beams 1 have pivoted thereto by a rod 14 or otherwise secured, bifu rcated goose-neck standards l carrying covering-shovels 16. In advance of the standards 15 the saine are connected by means of a transverse tie-rod 17, and to this is secured a central furrow opening standard 18.

The rectangularcastmetal frame 19 is provided upon its rear side with a transverse strap, 20 offset from the remainder of the frame and loosely mounted for pivotal movement upon the rod 17. This frame is provided at its upper inner corner with a bearing opening 21, and in said bearing opening there is loosely journaled a rotatable powertransmitting inclined shaft 22, whose lower end passes through the opening 12in the hood and is provided with a small pinion 24 designed to engage with and be rotated by the toothed hub ot' the axle. It will be seen that through the medium of this hood all dust is prevented from gaining access to the pinion of the inclined power-transmitting shaft and the toothed hub of the ground-wheel; and furthermore, that the parts composing this IDO portion of the machine may be readily separated for cleaning, repairing, &c.

Between the tierods 14 and 17 and im mediately in rear of the furrow opening shovel carried by the latter there is located a transverse tie-rod 25, whose ends project beyond the beams 1 and are connected with the lower ends of the handle-bars 2G, Whose rear ends project upwardly above and to the rear end of the machine where they are connected by suitable rungs 27. They also have secured adjustably thereto strap-braces 2S whose lower ends are secured to the transverse tierod 14 of the frame, whereby the handle-bars are supported rigidly in position.

Upon the tie-rod there is supported a d sleeve 29 from which there Yrises a pair of standards 30. These short standards 30 support a base-ring 31 which constitutes the bot? tom of the hopper 32, which latteris cylindrical and mounted thereon. Brackets 33 eX- tend from the inner edge of the base-ring and support a stationary disk 34, the said disk being provided with a central upwardly disposed and internally threaded hub 35 and a surrounding annular raised bearing-track 36. Within the track the disk is provided with a seed discharge-opening 37.

3S designates the seed-disk, and the same is provided with a central opening 39, whereby it is adapted to revolve upon the hub, and its under side rests upon the annular track. The periphery of the disk is toothed as at 40, and the said disk is provided with a series of seed-openings 4l, which are designedto be consecutively brought into register with the seed-discharge of the stationary disk.

Arranged over the seed-disk is the cut-off 42 andthe same is provided at a point above the discharge-opening in the stationary disk with a closed portion, the remaining portion being open or provided with slots 43. The

ut-off has a central opening 44 which fits loosely over the upper end of the hollow hub of the stationary seed-disk, and a screw 45 is inserted int-o the upper end of the hood in a removable manner and its shoulder bears upon the upper side 0f the cut-off, thus giving the requisite tension to the seed-disk. The opposite edges of the cut-off are provided with shallow recesses, which receive brackets that support the stationary disk under the base-ring. A short stub-shaft 46, depends from the under side of the base ring in line with the power-transmitting shaft, and loosely journaled upon said stub-shaft is a gear- Wheel 47, the same having its teeth engaging the teeth of the seed-disk at one side and at its opposite side projecting beyond the baseri'ng and toward said power transmitting- Shaft. Y.

The power-transmitting shaft is provided beyond its bearing in the bearing-frame with an adjustable collar48, the same terminating at its outer end with a ratchet Wheel 49 and held upon the shaft at any desired point by means of a binding screw 50. Beyond the adjustable collar just described there is a oo nical head 51, the said head being provided with a plurality of gears 52, 53, and 54, which number may be increased or diminished as desired. The gears are graduated in size, theY smallest gear being at the top of the coneshaped head. The front side of the head is provided with a pivoted pawl having an angular rear ond 56, which is pivoted bya pin 57 as shown.' The head has,furthermore, secured thereto a spring 5S, the free end of which lies upon the pawl and normally presses it into engagement with the ratchet Wheel. It will be seen that the pawl may be swung to a vertical position and the spring will not act to throw it into engagement with the ratchet-wheel. but will serve to support 1t in said vertical position and therefore out of engagement with the ratchet-Wheel.

It is obvious that the cut-oif may be removed and in lieu thereof the disk 59 lnaybe substituted. This disk 59 as shown in detail is provided upon its under side with lugs 60 which engage with openings inthe seed-disk, so that the said disk 59 will move with the seed-disk.' The disk 59 is further provided with peripheral or radial arms 61 and with a vertical arm 62. This disk is used when the machine is employed for planting cotton, and during the operation the radial arms or teeth engage with the teeth of a small feed-wheel 63, which is mounted upon a shaft 64 journaled in bearing-ears 65 located infront and in rear of a seed-slot 66 formed in the base ring at the rear side thereof. The slot is of T-shape and has its widest portion occupied by flutes 67, with which the small Wheel is provided at its rear side. A sliding cut-olf V68 of inverted L-shape has lugs 69 that engage with the slot, and at its rear side depends below the base-ring where it is perforated to receive the said shaft. The shaft is provided at its rear end with a milled nut or disk, whereby it may be rotated and interposed between the outer depending end of the cut-off and the outer ear is a coiled spring 70. The front end of the shaft is threaded in the front ear, so that by rotating the same through the medium of the milled-nut ordisk the cut-off may cover more or less of the flutes.

Pivoted to the intermediate transverse tierod 25 is the seed-spout 72, and a link 73 connects the same loosely with the furrow-opening standard.

Various changes in the construction of my invention Will readily suggest themselves to those skilled in this class of machines, and I therefore do not limit my invention to those herein shown, but hold that I may vary the same to any degree and extent Wit-hin the knowledge of the skilled mechanic.

Whether the corn or cotton-disk is employed the operation of the machine is the same, and is as follows The rotations of the ground-wheel transmit motion to the conveying-shaft and the ratchet-Wheel carried thereby, said ratchet-wheel communicating motion IOO IIO

to the conical gear-head, and said gear-head to the intermediate spur-gear, which then communicates motion to the seed-disk, operating the latter to discharge seed or through the medium thereof to rotate the cotton-disk. In order to change the speed of rotation of either disk, it is simply necessary to loosen the binding-screw in the adjustable collar and move the conical head so that the desired gearwheel thereof may be engaged with the spurgear. This, of course, necessitates raising or lowering the rear end of the conveyer-shaft, and the same is permissible by reason of the pivoted frame that forms the bearing for said shaft. The frame may be retained in any of its adjusted positions by a tightening of the nut on the tie-rod 17 upon which said frame is mounted. The planter is of course provided with the usual draft-devices or bail and with any other' auxiliaries thatmay be desired.

Having described my invention, what- I claim is- I. In a planter, the combination with the frame, the hopper, the rotatable seed-disk having teeth, and the intermediate spur gear engaging therewith, of the ground wheel and its axle, an intermediate conVeyer-shaft, means for communicating motion from the groundwheel to the conveyer-shaft, a conical head loosely mounted upon the upper end of the conveyer shaft and having a series of graduated gears for engaging the intermediate spur-gear, means for adjusting said conical head, and means for adjustably supporting or journaling the shaft, substantially as specied.
