SPECIFICATION forming part of Letters Patent N0. 239,799, dated April 5, 1881.

Application filed June 15, 1880. (Model.) l

To all 'whom it may concern:

Be it known that I, JAMES Hnnva JoNEs, of the city of Rockford, in the county of Winnebago and State of Illinois, have invented new and useful Seed-Planter and Oultivator, of which the following` is a specification.

This invention relates to improvements inY which the carrying-wheel is omitted and somel of the parts are broken away to more clearly reveal the parts. Fig. 3 is a rear eleva-tion. Fig. 4 is an isometrical representation of the seeding mechanism and of the parts immediately connected therewith. Fig. 5 is an isometrical representation of one of the stirrerheads with stirrer-arms attached. Fig. 6 is a plan view ofthe clutching mechanism and shifting-levers with the clutch in gear. Ofthis` plan view, Fig. 7 is al1-elevation with sprocket-wheel removed, and in which the position of the shifting-levers are shown. Fig. Sis a like plan view of the same parts as shown in Fig. 6; but in this figure the clutch is out of gear. Of this plan view, Fig. 9 is an elevation with sprocketwheel removed, and in which the position of the shifting-levers is shown. Fig. l0 is a central section, showing the slipconnection of the master-wheel `of the gear-V train with the shaft. Fig. 1l is an isometrical representation of the seed or picking wheelsl and a portion of the hopper. Fig. 12 is a transverse section of the seed-spout on dotted line X ot Fig. 3.

In the gures, A represents an axle-tree, of suitable dimensions, having fixed to its end portions axlearms B, which receive carryingwheels C, tted torevolve thereon. j

D are tongue-beams, having their rear ends joined to the axle-tree, from which points they converge, meeting forward at acentral point, producing a suitable tongue. A cross-bar, E, is fixed to the under side of the tongue-beams,

forward of the axle-tree and parallel thereto. To the end portions of this cross-beam and to Vthe tongue-beams are fixed pendants F. The

levers, pivoted on supports rising from the' main frame, and Atheir forward portions are connected with the drag-bars, rearward of their hinged connection with the pendants, by means of suitable hook -link connection, through which, by means ofthe levers, the drag-bars can be raised a nd lowered. The forward ends of the raising and lowering levers are fitted with an arm, projectingforward therefrom to engage the teeth of ratchets K, fixed to the tonguebeams, from which they rise to receive the arm projecting from the forward end of the levers, operating to hold the beams at any elevation within the limits of the devices. The-upper portion of the lilik -conncction of the levers with the drag-bars are of hook form, adapted to embrace the tongue-beams when the dragbars are raised, to limit the lateral swaying thereofin transportation.

At L are represented beams suitably joined at their rear ends, producing a V-formed frame, having a drivers seat, M, mounted on its rear end. The forward portion of this seat-frame has its fulcrum-support on the axle-tree, and its extreme forward ends, in advance thereof, are held in position and made vertically adjustable to raise and lower the seat over its fulcrum-support by means of brackets N, fitted to engage the beams, and made vertically adjustable in their connection with the tonguebeams. Y

At .P are represented foot-supports, adjustably 'xed to the drag-bars to receive the feetV of the operator, to enable him to control the lateral movements of thedrag-bars. These several parts hereinbefore described, in their construction, arrangements, and operation, are substantially the same as like parts represent- IOO ed and described in my application for improvements incultivator and seeder combined tiled in the United States Patent Office on or about April 15, 1880, and I do not therefore deem it necessary to enter into a more detailed description of the several parts and. of their operation in this specification.

At lt is represented a seed box or receptacle, of rectangular form in plan, having a curved bottom semicircular in cross-section, having its center portion enla-rged in depth in barrel form, which, in connection with a rotary stirrer or agitator, operates to carry the seed to the center of the receptacle to subject it to the action of the seed-wheels. This seed-box is placed in the lengthwise center ot' the hereinbefore-described machine, forward of its axletree and Linder the main frame, having the axial center of its curved bottom crosswise of the machine and parallel with the axle-tree thereof, and in this instance is supported in position by means of a transverse bar, a, rectangular in cross-section, fixed to the forward side of the box parallel with the axial center of its curved bottom.

At b are represented angle-brackets having their vertical arms fixed to the transverse bar a on the'seed-box and their horizont-al arms fixed to the cross-bar E of the main frame of the machine, which fixes the seed-box iirml y in position thereon.

At 0 are represented seed-distributin g or picker wheels, of disk form, about one-half of the periphery of which is formed with pickerteeth resembling the teeth of a saw, and the remainder of their periphery is reduced to a circle about equal in diameter to the portion formingthe bottom of the teeth. These wheels, suitably separated and placed with the toothed portion of the one by the side of the plain portion of the other, are mounted on a shaft, d, to revolve therewith. This shaft d is fitted to revolve in suitable bearings fixed to the seed-box, in such relative position therewith that the seed-Wheels extend into the seed-box, entering through transverse slots e cut in its rear under portion. These transverse slots, on the inner surface of the curved bottom, are provided with uprising cheek-pieces f, formed to protect the sides of the disk seed-wheels from 'the action of the seed in the hopper, and having their upper edge curved to coincide with the periphery of the plain portion of the seedwheels. The space between the seed-wheels on the inside of the seed-box is fitted with a curved bar, h, which rises to coincide with the curve of the plain portion of the periphery of the seed-Wheels. With this arrangementit Will be seen that in the rotations of the disk seed- Wheels only the'toothed portion thereof will rise above the guards, consisting of the cheekpieces f and the curved center bar, h, and that these portions will act uponthe seed contained in the seed-box alternately on opposite sides.

The outer portion of the seed-wheel shaft is fitted with a gear-wheel, i, the teeth of which engage the teeth of a counter gear-wheel, i', mounted to revolve on a stud projecting from the end of the seed-box, and carrying a gearpinion, if', the teeth of which engage the teeth of the master gear-wheel 11"', mounted on the main driving shaft 7c, which is' supported to revolve in the axial center of the curved bottom ofthe seed-box in suitable bearings in its ends, and in a bracket-arm bearing, l, fixed to the end portion of the transverse bar a.

The relative size of the wheels of the geartrain connecting the seeding device with the driving-shaft will determine the distribution of the seed. These, however, may be varied, and additional sets may be made of various proportions to meet the various requirements of the distribution of the seed. The mas- -ter-Wheel i, mounted on the shaft It, is

held in position thereon bya friction mechanism, to permit the shaft to revolve therein t prevent breakage when the parts of the seeding mechanism become clogged or otherwise disarranged. This friction mechanism employed in this instance consists in the chambered hub m, provided with a curved spring, a, and a set-screw, 0, fitted to operate upon the spring to hold the wheel to the shaft with greater or less force as the screw is moved in' one or the other direction.

The outer end of the main driving-shaft k is provided with a sprocket-toothed wheel, p, fitted to revolve loosely thereon, and capable of a limited endwise-sliding movement on the shaft, and having its hub end fitted in clutch form to engage a clutch-pin passed through the outer end of the shaft. The inner end portion of the hub of this sprocket-wheel is provided with an annular collar, p', which, in connection with asbifting-lever, serves to hold the clutch disengaged.

At p and 19 are represented shifting-levers, pivoted at one end to the arm ofthe bracket-bearing l in such a manner that their free ends may swing freely in a vertical plane. Ot' these the lever p is provided with a notch, 1', in its lower edge, adapted to receive the main shaft betweenthe bracket-bearing and the inner end of the hub of the sprocket-wheel, as shown in Figs. 6 and 7, which serves to hold the clutch engaged to impart motion to the shaft and to the seeding mechanism throughv its gear-train connection therewith. The lever p is provided with a notch, r', in its lower edge, adapted to receive the hub of the sprocket-wheel between the collar p and the wheel, which serves to hold the clutch disconnected, as shown in Figs. 8 and 9.

At s is represented a seed-tube having a curved front wall, s', and opening iiaring side walls, s, producing a seed-tube open in its rear, and in cross-section of the form represented in the sectionalvicw at Fig. l2, having the upper portions of its edges, as at t, formed to receive the 'hinge-slidest, made vertically adjustable thereon by means of a series of holesformed in the slides and in the IOO IIO

IIS

'outturned edges t of the tube, adapted to receive a suitable screw-bolt to fix them in position when adjusted. The upper end of the slides t are titled with outward-projecting trunnions t, fitted to enter suitable perforations in ears t, which depend from the curved bottom of the seed-box, producing a hinged connection of the seed-tube therewith, to permit it to swing in the lengthwise direction of the machine.

At T is represented a furrow-opener, which in this instance is of knife form, and is suitably xed in a vertical position to the front of the seed-tube, having its knife-edge forward.

At 1r is represented a brace, formed of like bars, havingtheir forward opened ends joined by hinge connection ,to the seed-tube at a suitable point below its hinged connection with the seed-box.A The rear portions of the bracebars are separated, having a hook or catchblock, u', placed between them at a suitable point, and fixed in position by a screw-bolt passed transversely through the bars and catchblock. 'This catch-block extends below the bars, and produces ahook adapted to engagea transverse bar, c", placed between the rearward portion of the drag-bars, having its ends joined thereto by an eye-joint connection. This hookconnection of the brace with the transverse bar serves to hold the seed-tube elevated for transportation or other purposes requiring it to be suspended.

The brace-bars, rearward of their hook-block connection, are provided with asafetyslipdiook connection, consisting of a lever-hook, n, fitted to engage the transverse bar, and are pivoted between the brace-bars on a suitable screw clamping-bolt, by means of which it may be held with greater or less force. This safety slip-hook, when inthcposition represented in the solid lines in Fig. 2, producing an acute angle with the rear portion of the brace, serves to hold the seedtube against the earth-resistance in opening furrows to receive the seed, and when it meets with rigid obstructions the increased resistance will cause the safety-hook to turn on its pivot to the position in dotted lines, which will permit it vto slide over the transverse bar and permit the tube to rise and pass the obstruction, when it can be readjusted in working position. By this construction and arrangement of the hinged secd-tube, having an open rear, and its relative arrangement with the seat, the driver mounted thereon is enabled to detect irregularities in the distribution of the seed.

At Tl is represented a sprocket-wheel, iixed to the carrying-wheel to revolve therewith, which is placed in the same vertical plane with the sprocketwheel p. These sprocket-wheels are connected by a chain-belt, w, havinglinks -l tted to engage the teeth thereof in sucha manner thatthe forward `movement of the ma- `chine will ir'part motion to the seeding dcvices. Y i

At 'ab' are represented reel-heads mounted on the main shaft in the seed-box, one at each end thereof, fixed to revolve with the shaft. These reel-heads are fitted with arms w, extending lengthwise of the shaft, overlapping each other over the seed-wheels in the center of the seed-box, and Vare placed in such relative position with each other that the end portions ofthe arms of each head extend between the arms ofthe opposite head, andthe several arms are of their-regular curved form represented in the drawings,iitted to agitate theseed from the chain-belt and the hinged seed-spout,or

by removing the seed-box and its appliances; and it is capable of use as a seed-planter, in which capacity it will only require the removal of the shovels connected with the drag-bars. It is also capable of use as a seeder and cul tivator to cover the seed, in which capacity the inner shovels only will be required; or it is capable of use as a complete scederand cultivator, in which capacity the complete machine as a whole may be used.

In use as a cotton-seed planter the seed is placed in the seed-box and the other parts of the lnachine properly adjusted. The machine is then put in motion, and the forward movement thereof will produce a furrow to receive the seed, and will put in motion the seedwheels, the teeth of which, in their rotation, will engage the fibrous material remaining on the seed alternately on opposite sides, and carry the seed, with their movement, through the openings in the curved bottom of the seedbox in front of` the 'seed-wheel, and deliver it into the seed-spout, through which it descends into the opened furrow. This action ofthe seed-wheels, in connection with the alternate action of the stirrers from opposite sides, will prevent clogging or packing of the seed and insure a regular and uniform distribution thereof, and the cotton-fiber adhering to the seed, and heretoforethe greatest obstacle in the way of a uniform distribution thereof Ithave utilized as a leading feature to insure a more uniform distribution of the seed than has heretofore been produced as known to me. With this distribution of the seed, in the onward movementof the machine the inner shovels will cultivate or stir the earth on each side of the furrow and cover the seed.
