SEEDING-MACHINE.

SPECIFICATION Iforming part of Letters Patent No. 427,420, dated May 6, 1890.

Application iiled December 19, 1889. Serial No. 334,303. (No model.)

To all whom, it may concern:

Be it known that I, HAI-:LAN SMITH How- ARD, a citizen of the United States, residing at Madison, in the county of Dane and State of Visconsin, have invented certain new and useful Improvements in Seeding-Machines, of which the followin is a specification, reference being-had therein to the accompanying drawings, in which- Figure l represents a plan view of my machine complete, a portion of the seed-hopper being broken away to better show some of the parts; Fig. 2,a longitudinal vertical sectional view of the machine; Fig. 3, detail perspective views of the seat-beam and a pressurebar connected thereto; Fig. 4, a detail perspective view of the upper endet one of the curved pressure-rods and its attachments; Fig. 5, a detail side elevation of one ot the drill-tubes and furrow-openers and pressurewheels attached thereto; Fig. 6, a horizontal sectional view showing connection of wheelarms to grain-spout of shoe Fig. 7, a detail view of the adjustable corrugated disks employed to clamp the pressure-wheel arms to the grain-spout of shoe; Fig. 8, a detail View of the lug on rear end of grain-spout, and Fig. 9 a detail view of connection between shoes and front beam of the frame.

The object of this inventionA will fully appear inthe course of this specification.

In the drawings, a designates a suitable axle supported pivotally upon apair of transporting-Wheels and provided near its ends with a pair of forwardly-projecting arms b, these arms being rigidly bolted to the axle. I-Iung pivotally to the forward ends of the arms b is a rigid horizontal frame consisting of the long transverse beams c c and the short end beams d d. The pole or tongue e is rigidly secured to this frame about midway between its ends. The seat-beam f is arranged in line with the tongue and pivotally secured to the same by means oi eyeboltsf, this seat-beam extending rearwardly under the axle and pivotally hun g thereto by means of another pair of eyeboltsf, the drivers seat being mounted upon the extreme rear end of the beam. An operating-lever g is pivoted upon a toothed segment seemed upon the axle and extended back within a convenient reach of the drivers seat, the forward end of this lever being connected by a piv'- oted link g to the rear end of the tongue.

The operation of raising and depressing the horizontal trame is as follows:

To depress the frame it is simply necessary to elevate the rear end of the operating-lever, whereupon the axle will be permitted. to rock in a forward direction, so as to depress the forward ends of the arms l), thereby permit.-

ting the horizontal pivoted frame composed of beams c and d to fall the desired distance.

By means of a spring-actuated bolt (of the usual construction) on the operating-lever and the toothed segment the frame may be held at any desired elevation.

To elevate the iframe c (l, the operator simply depresses the rear end of. the operatinglever, which action will raise the said frame through the medium of the pivcted rod or link g and cause the axle and arms Z9 to assume their normal horizontal positions.

The pivoted horizontal frame e d carries the seeding mechanism, which is constructed as follows: Pivotally secured by means ot brackets h to the under side of the beam c are the rearwardly-extending shoes h, provided with the usual seed-spouts h, into which the seed is conveyed through hosez' from the hopper z", mounted upon the arms b or at any other suitable point. The spouts and shoes are rigidly braced by the crossed rods j, which extend from ears formed on the brackets h to ears formed on the spouts h, the ends of therods passing through holes in the ears and drawn tight by means of nuts.

Formed in the rear side of each spout 7L near its top is a lug or wing 7c, provided with a central bolt-hole and duplicate beveled pro-- jections 7c at diametrically-opposite points` on both sides, these beveled or semi-conical projections being provided with radial ribs or eorrugations, as shown.

Clamped on opposite sides of the lug 7c by.

means of a horizontal bolt and disks Z are the forward ends of the arched parallel bars m, i

between the rear ends of which and in direct line with the shoe h is journaled the presserwheel m. To raise or lower the presserwheel with respect to the shoe, it is simply necessary to loosen the connecting-bolt and turn the disks Z in either direction (in a forward direction to lower and viceversa to IOO raise) and tighten the bolt again, these disks being prevented from turning by corrugated projections Z', which engage the projections 7c ou the lug. In this way the wheel maybe rigidly but adjust/ably held in any position with respect tothe shoe, so that the seed may be planted deeply or shallow, as the farmer may desire.

To prevent the arms m oscillating' ou the connecting-bolt, the inner faces of the disks Z are provided with stop-lugs Z, the lug on one disk being adjusted tol bear against the forward. edge of the adjacent arm fin above the bolt, while the lug on the other disk bears against the arm m below the bolt, thereby.

preventing` the slightest oscillation of the arms attached to the wheel.

If it is desired to permit the shoe to fall below the adjusted point with respect to the wheel, in order that it may drop into depressions in the field while operating, a limited downward movement may be allowed it by simply removing one ofv the disks (the righthand one in the drawings) and turning its smooth side inward, when the arms m will be allowed to oscillat-e freely between the lower l lugl and theforward corrugated projections l 7c', as is evident. Thus permitting the shoes a limited downward movement with respect to the presser-wheels is very advantageous in that it adapts the machine for thorough planting on rough lumpy ground, inasmuch as the shoes will be permit-ted to accommodate themselves to the irregular surface and will not be lifted out of the ground whenever the presserwheels are elevated by lumps or other objects, as is evident.

If it is desired to permit the presser-wheels to have free up-and-down movement with respect to the shoes, this may be accomplished by simply removing both disks and turning' their smooth faces inward, thereby permitting the bars m to oscillate freely between the corrugated projections 7c on the lug k.

Rigidly connected to each one of the arches and extending upwardly therefrom and passing loosely through aperturesinthe pressurebeam cof the swinging frame are curved metallic rods n, provided with washers on their upper projecting -ends to prevent them being withdrawn from their apertures in the pressure-beam, the washers being held on the rods by means of removable split pins.

Coil-springs surround the rods n and exert a constant downward pressure upon the presser-wheels and shoes, thereby permitting Ythem to yield independently of each other to conform to the irregular undulations of the soil, and at thesame time to insure every shoe being pressed rmly into the soil the distance for which it is set.

If it is desired to increase the pressure upon the Wheels and shoes, a transverse beam 0 (shown in Figs. 2 and 3) may be connected to the arches of the presser-wheels by short depending bolts o', (passed down between thcv bars of the arches,) and kept pressed norvoperation or not.

mally down by means of a spring surrounding a vertical rod o, connecting this baro to the seat-beainf. In this way the driver may depress the drills simultaneously by simply pressing down with his feet on the beam o. A portion of the weight of the driver and the constant pressure of thespring or rod o will also serve to augment the pressure on the drills.

By securing` and mounting the seat-beam and seat as shown and described the weight of the driver will tend to balance the machine ou its axle-spindles, and thereby relieve the horses necks of all weight or strain. The strain on the horses necks has always been a drawback with this class of machines; but my manner of arranging the frame and seatbeam materially overcomes this objection.

' An essential advantage in constructing and operating the machine in the manner shown and described is that the shoes and wheels attached to the swinging frame c c d d are raised bodily from the ground by a simple movement of the operating-lever, the said frame remaining always iu a horizontal position whether the planting mechanism be in It will be also observed that the weight of the driver and the frame will be thrown upon the planting devices, thus insuring a positive pressure upon the shoes and covering-wheels at all times.

The manner of connecting the pressure or covering wheels to the shoespout has many advantages, as hereinbefore pointed out, inasmuch as the machine may thereby -be adapted to various kinds of planting.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is-
