invention, such as will enable others skilled in the art to which it appertains to make and use the same.
This invention relates to a combined lister plow and corn-planter; and it consists of cer ta'in improved features of construction and combinations of parts, as will be hereinafter more fully described, and particularly pointed out ,in the appended claims.
In the accompanying drawings, Figure 1 is a side elevation of a combined lister plow and planter embodying my invention. Fig. 2 is Fig. 3 is a vertical longitudinal section. Fig. 4=isa top plan view. Fig. 5 is a horizontal section through the standard and moldboard and a detail top plan view of the furrow forming and closing Fig. dis a top plan view of the seeddropping mechanism.

gitudinal section of the same. Fig. Sis a detail longitudinal section through one end of the axle and hub of the associated carryingwheel and shows the use of the auxiliary sleeve. Fig. 9 is a perspective view of the auxiliary sleeve. Fig. 10 is a view similar to Fig. 1, showing the application of a check- Fig.11 is a rear elevation, partly in section, of the hopper and seed-drop.- ping mechanism and applied check-row attachment, and Fig. 12 is a side elevation of the same.
1 in the drawings represents the tongue and main frame-beam, to which is attached the arch portion of the arched axle 2, which is stayed by the inclined braces 3. 4. is a seat secured to the beam 1, and 5 a foot-rest bar secured to the braces 3.
Below the beam 1 is disposed a plow-beam 6, which is adj ustably hung at its forward end from the beam 1 by a link 7 and which terminates at its rear end in a standard 8. Av
coil-spring 9, secured at one end to the bar 5 and at its other end to the beam 6 adjacent to the said standard 8, opposes a resistance to the downward movement of said beam 6 and serves to assist in raising it.
On the axle-spindles 2 are mounted the carrying-wheels 10, whose hubs 10' are held in place by collars 11, fixed by set-screws 12, and I means of which the yoke may be swung to raise and lower the beam 6, and this lever is provided with a pawl 16, adapted to engage a rack 17, fixed to the arched portion of the axle or some fixed portion of the frame, whereby the lever may be locked to hold the beam 6 in the desired adjusted position. By this construction the furrow formiugand closing devices, hereinafter described, may beadjusted for work as the occasion requires or raised above the surface of the ground. The beam 6 carries an adjustable disk colter 18,
supported by a bracket or hanger 19 and stayed by a brace 20. The ends of the axle are made of such length as to admit of the application thereto between each hub 10' and sleeve 13 of an auxiliary or spacing sleeve 21, by means of which the wheels 10 may be spaced farther apart when desired. The hub 10' of each wheel is bored to form an oil-chamber 22, closed by a screw-plug 23 and containing aball or sphere 24, which runs in contact with the axle-spindle and keeps the same lu bricate'd. This ball serves both as a regulator and distributor, whereby waste of oil is prevented.
On the lower end of the standard 8 is a lay, double-moldboard plow, or furrowopener 25, which is approximately of V form in cross-section, its sides sloping down from the center ridge to throw the earth each way. Above this is disposed a similarly-shaped vertical moldboard 26, and in rearof said board are furrow-opening disks 27, which are set diagonally to the beam 6, with their forward edges closer together. The lay and moldboard are made of V form in cross-section, so as to cover the space between the front edges of the disks, so as to begin the formation of the furrow, which is completed by the disks. In other words, the lay or plow-point 25, the moldboard 26, and the disks 27 cooperate to form a V-shaped furrow-opener, the point or vertex portion of which is formed by the plow. By this construction the dirt is more eifectually thrown out and removed from the furrow. The disks are adjustably mounted as follows: At the rear of the standard 8 are two angular castings 28, whose horizontal arms a a. diverge and are formed with spindles 29 and whose vertical arms 6 b overlap and lie against the rear surface of the standard. In the said arms I) b are formed vertical slots 6 through which passes a bolt 30, securing the same to the standard. These slots allow the castings 28 when loosened to be adjusted vertically and also swung laterally on the bolt 30 as a pivot, and then upon tightening up the nut 30 on the bolt the castings will be clamped firmly in adjusted position. On the spindles 29 are mounted sleeves 31, which are axially adjustable thereon and adapted to be held in position by set-screws 32. Each sleeve 31 carries a head 33, which interlocks with a similar head 34, the meeting faces of the two heads being grooved or serrated to form matching recesses or projections for this purpose. Abolt 35 clamps the two heads together and holds their meeting faces in locking engagement. The head 34 carries a spindle 36, on which is fitted the hub or sleeve 37 of the disk 27, by which said disk is mounted to revolve. By loosening up the bolt 35 and adjusting the head 34 it is apparent that the disk 27 may be set backward or forward and vertically adjusted to a limited extent without changing the position of the casting 28, also that by the mounting of the parts in the manner described the disks may be set at an angle relative to the beam and at any desired degree of inclination to the vertical. Two horizontal brackets or bars 38 and 39 are disposed in rear of the castings 28 and are formed with the vertical arms 0 d, through which the bolt 30 passes and secures them to the standard. The bracket 38 carries at its rear end a subsoiler 38, which lies in the line of the plow-point 25 and deepens the trench orfurrow and also removes any ridges or cores which may be left by the said plow-point and disks. The bracket 39 is bifurcated at its rear end, forming diverging arms c c", which carry shovels 40, Whose function is to throw the earth back and to cover the seed. In order to keep the disks 27 clear of accumulated soil, scrapers 41 are used, these scrapers being carried by arms 42, which are carried by the hubs 37 of the disks, the arms having hook-shaped outer or free ends to project over and beyond the edges of the disks and support the scrapers on the outer faces of the disks, as will be apparent by reference to Figs. 1 and 2.
At the rear of the beam 1 is mounted a hopper 43, whose bottom 44 consists of a plate having projecting arms 45, provided with depending hangers 46, in which is journaled a transverse shaft 47, supported by braces 48 from the axle 2. The hopper is hinged or pivoted to said plate to permit accessto the interior seed dropping mechanism. This mechanism comprises a seed-plate 49, pro vided with openings 50 for the feed of seed therethrough, which openings are arranged to come successively in register with a seedopening 51 in the plate 44 as the seed-plate revolves, which opening 51 is disposed in alinement with a drill-tube 52, which conducts the dropping seed to the furrow in rear of the subsoiler 38. The seed-plate 49 is mounted to rotate upon the pivot-bolt 53 and is secured to a beveled gear ring or disk 54, driven by'a beveled pinion 55 on the shaft 47. The gear ring or disk is provided with upwardly and inwardly projecting lugs 56, under which the seed-plate fits, and these lugs carry set-screws 57 to clamp the seedplate in position. This construction enables anyone ofaset of interchangeable seed-plates to be used. The shaft 47 carries at one end a beveled pinion 58, meshing with a similar pinion 59 on the upper end of a drive-shaft 60, mounted to slide longitudinally and to rotate in bearing-brackets 61 on one of the braces 48, the lower end of said shaft 60 carrying a pinion 62, meshing with a gear 63 on one of the wheel-hubs 10, by which construction of gearing the seed-plate is continuously rotated as the planter moves forward.
In order to throw the seed-plate in and out ofgearsimultaneouslywith thedownwardand upward adjustments of the beam, whereby the furrow forming and closing devices are thrown into and out of operation, I provide means for adjusting the shaft 60 to move the gears 59 62 into and out of mesh with the gears 58 63. This adjusting means comprises a grooved collar 0, fixed to the shaft 60, and between which and the adjacent bearing 61 is interposed a coil-spring g, which normally holds said shaft 60 down with the gears 58 59 and 62 63 in mesh, whereby when the machine is in motion the shaft 47 will be driven. A vibrating lever h is pivoted to a bracket h, fixed to the sleeve 13, and has a forked arm 71 which engages the grooved collar 0. The
opposite arm of said lever h is located in the path of movement of a laterally-bent finger t" on one arm of a rocking operating-lever z', pivoted to one side of the arch 2. The opposite arm of this lever 2' is also provided with a finger 1?, which lies in the path of movement of the yoke 14. When the yoke is swung upwardly to raise the beam 6, and thereby elevate the furrow forming and closing devices, the levers h tare actuated to slide shaft 60 upwardly against the tension of spring g, thereby throwing the seed-plate out of gear. When, on the other hand, the yoke 14 is moved downwardly, the shaft 60 and lovers 7?. 'i will be restored to their normal positions and the gears 58 59 62 63 brought into mesh, thus throwing the seed-plate into gear again.
III
When it is desired to use a check-rower, the shaft 60 is dispensed with and an operating wheel or disk 64 applied upon each end of shaft 47, as shown in Figs. 10, 11, and 12. This wheel or disk 64 is provided with tappetarms 65, adapted to be engaged by the knots or projections on the check-row wire 66. This wire passes over a pair of guide-pulleys 66 and down under the wheel 64, which lies between said pulleys, and between the forked arms 65. The pulleys 66 are carried by a bracket 67, hinged or pivoted at 68 to the frame and held in position by a spring-actuated movable supporting device, the same consisting of a bracket-arm 69, pivoted at 69 to one of the hangers 46 and having a long arm f, which bears upon the bracket 67, and a short arm f is acted upon by a spring 69 to project the arm 69 upwardly to hold the bracket 67 supported. The armfis connected with an operating cord or like element 70,1eading therefrom around a suitably-arranged guide-pulley 70 to the seat 4, by means of which the driver from his seat may release the bracket to allow the same to drop, thus depressing the pulleys 66 and dropping the wire 66. The operation of the seed dropper may in this manner be arrested at any time.
From the foregoing description, taken in connection with the accompanying drawings, the construction and operation of the invention will be readily understood without requiring a more extended explanation.
Various changes in the form, proportion, and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.
Having thus described myinvention, what I claim, and desire to secure by Letters Patout, is-
