PLANTER.

SPECIFICATION forming part of Letters Patent IVO. 610,771, dated September 13, 1898. Application filed September 4, 1897. Serial No. 650,660. (No model.)

T0 all whom, it may concern.-

Be it known that I, JAMES DROMMOND SCHOFIELD, a citizen of the United States, residing at Dallas, in the county of Dallas and State of Texas, have invented certain new and useful Improvements in Planters; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in planters, the same having special reference to that class of planters employed for automatically planting cotton-seed, corn, dac. and wherein the feed is operated by a driving mechanism set in motion by the planter-supporting ground-wheels or, as herein shown and as preferred, the covering-disks.

The main objects of my present invention are to devise a convenient and simple means for converting and transmitting motion in a positive manner from the planter-supporting covering-disks or the ground-wheels, whichever are employed, to the driving mechanism; to provide for a thorough protection of the necessary gearing against the admission of dust and grit, as well as a convenient means of access to the same; to provide a conveniently-operated adjustment for the coveringdisks when employed, whereby their relative angular location may be changed at will and instantly, so that the planter is thereby adapted and caused 'to cover and plant at the depth desired; to provide means whereby the covering-disks may be independently adjusted irrespective of the joint adjusting means before mentioned, so that they may be subsequently jointly adjusted with relation to each other and also with relation to the line of draft, and thus the machine be forced to travel in a straight line and obviate all tendency to travel sidewise, and, finally, to provide a novel means for shifting or throwing the driving mechanism into and out of operative connection with the feed devices and for retaining the corn, cotton, or other seed disk in position for light running and adapted for easy removal, whereby the one may be readily substituted for the other Without an absolute removal of the retaining devices employed.

Various other though minor objects of my invention will appear in the following description, and the novel features claimed for my invention will be embodied in the appended claims.

Referring to the drawings, Figure l is a perspective view of myv improved planter. Fig. 2 is a rear perspective of the same. Fig. 3 is a vertical transverse sectional view of the hopper and the feed and operating mechanisms. Fig. 4 is a detail in perspective of the supporting-yoke and gear-case. Fig. 5 is a side elevation and partial section of the diskadjusting lever and its connections. Fig. 5 is a detail of the adj listing-link of said lever. Fig. 6 is a perspective view of a portion of the hopper. Fig. 7 is a detail of the upper swiveled ring and its axle. Fig. 8 is a detail of the under side of a corn or cotton disk and also of the feed wheel or disk upon which it is mounted. Fig. 9 is a detail of the gear-case and the parts carried thereby. Fig. 10 is a detail of the shifting yoke and its operatingrod. Fig. l0 is a sectional view of hopperbottom with parts separated.

Similarnum erals of reference indicate similar parts in all the figures of the drawings.

My improved planter mechanism may be supported in position upon any suitable cultivater-frame, the one illustrated being preferred and comprising, briey stated, the beam l, bifurcated or divided at its rear end in the usual manner and at its front end provided with the usual clevis or other draft appliance or connection. The standard .2 of an ordinary plow or cultivator 3 is bolted to the beam l at the point of divergence, and immediately in rear is located the seed spout or discharge 4. A gage-wheel' 5 may be adjustably connected by a standard 6 to the front end of the beam l. l may also employ a reiiecting-mirror 7, mounting the same upon the beam in such manner as to be readily ad-,

j usted to reiiect the working of the seeder to the eyes of the operator, so that he can at all times readily see that the machine is pern forming its proper function in a satisfactory manner and therefore does not have to leave his position toascertain this fact. Of course handle-bars S may be employed, the same being bolted to the bifurcations of the beam and to any other suitable points. Such, however, would be omitted or removed when the planter IOO rated threaded lug 22.

is supported upon a riding cultivator for planting one or a plurality of rows simultaneously.

I preferably bolt to the rear bifurcated ends of the beam 1 a substantially U-shaped main yoke or frame 9, and the same may have its upper ends or terminals bent outwardly in a horizontal manner to form opposite rests 10, upon which .the bottom 1l of the hopper 12 may be mounted. The hopper-bottom may have formed at diametrically opposite points lateral extensions or lugs 13, through which vertical bolts 14 may be passed, said bolts also passing upwardly through openings 15, formed in the rests 10, which openings are preferably in the form of elongated slots, so that the hopper as a whole is capable of a slight adjustment with relation to the yoke 9.

16 designates a cast-metal cap comprising an upper disk 17, on the upper side of which is formed a pair of transverse parallel superficial ribs 18, cast thereon, and between which and seated on the cap is the lower transverse portion of the yoke 9. This cap may further comprise a depending annular liange 20, the same being of less diameter than the disk 17, from which it is extended and of which it is formed a part, whereby there is produced at the upper end of the cap an annular bead 21, which in reality is the projecting or overlying edge of the disk 17. The lower edge of the iiange 20'of the cap is cut away or recessed at nearly diametrically opposite points, as at 19, and at one side between these points has its edge provided with small lugs 2l and at the opposite side provided with a half-round depending perfo- An oppositely-disposed lower cast-metal cap 23 may also be employed, the same comprising the lower disk 24, annular flange 25, and lower annularly-disposed radiallyprojecting bead 26. The upper edge of the flange 25 of this cap is also cut away, as at 27, at nearly diametrically opposite points, so that when the annular Iianges of the two caps meet these cut-away or recessed portions combine to produce side openings in what constitutes an annular sectional gearcase. The flange of the lower cap is provided with nicks or shallow recesses 28,which receive the depending lugs 21 of the upper cap, and is also formed with a half-round recess 29 for the reception of the perforated and threaded lug 22. These ftwo caps are oppositely disposed and may be held in removable position by means of a pair of vertical binding-bolts .30,which depend through corresponding pair's of vertically-alining perforations, with which the disks of the two caps are provided, close up to the interior surfaces of their annular meeting flanges. are provided with central vertically-alining perforations 32, that of the upper cap having its perforations flanged on its under side. These holes or perforations 32 are in direct vertical alinement with similarly-flanged holes 34, formed at the center of the U-shaped The disks of the two caps main yoke 9, and also with the usual though larger opening 33, formed in the bottom 11 of the cylindrical hopper 12. Extending through-these four openings and journaled in the lower three is the vertical operatingshaft 35, which is also passed through the bored hub 36 of the ratchet-wheel 37, located below the hopper bottom. This ratchetwheel, which is in reality the lower member of a clutch, is surrounded by an annular flange 3S, upon which loosely rests a curved clutch-yoke 39, having three angularly-disposed trunnions 40, two of which are journaled in openings in the sides of the main or U-shaped yoke-frame 9, as indicated at 41, Fig. 3, and the other of which is engaged by a perforation 42 or otherwise loosely connected to the lower end of a vertically-movable rod 43, located at one side of the hopper-body 12. The rod 43 is slotted near its upper end, as at 44, and is engaged and guided by a headed stud or screw 45. The slot 44 is preferably of inverted-L shape, so that the rod may be depressed and moved laterally, so as to become locked against upward movement by reason of the neck of the stud entering the lateral branch of the said slot.

The ratchet-wheel37, before mentioned, is loosely mounted on the upper end of the operating-shaft 35, and its hub is longitudinally slotted, as at 46, through which slot projects a pin 47, which projects laterally from said shaft. By this means it will be seen that the ratchet-Wheel will have a vertical movement independent of the operating-shaft 35, but must rotate with the same. Aloose bearingcollar 4S may be mounted on the operatingshaft immediately above the bottom of the yoke 9, and between this collar and the lower end of the hub of the ratchet-wheel is located a spring 50, the same being coiled upon the operating-shaft and adapted to normally elevate the aforesaid ratchet wheel until its teeth engages operatively with similar teeth 51,formed on the under side of the feed-disk 52. The feed-disk 52, Fig. 8, is'located in the depressed central portion of the hopper-bottom, the ratchet-hub on the under side thereof projecting through the central opening in said bottom. The disk is provided with a central opening 53,through which the upper end of the operating-shaft projects, and with an external intermediate track-flange 54. The upper side of the flange 54 has formed thereon diametrically opposite lugs 55. A corn-disk or, as herein illustrated, a cotton-disk 56 may sur* mount the feed-disk 52. The corn or cotton disk may be formed in any usual manner for dropping corn through the openings 57, with which the bottom 11 of the hopper is provided, or for feeding cotton-seed horizontally or otherwise through the opening 58, Fig. 6,

also formed in said bottom 11. The latter opening may be provided with the usual gage or cut-off 59 and dropping-wheel 60; Whatever be the shape or configuration of the corn or cotton-seed disks, each has its bottom pro- IOO IOS

IIO

vided with a depending annular hub 6l of such size and shape as will adapt it to take over and fit the upper end of the feed-disk 52,

and the said hub 6l is recessed or notched at diametrically opposite points, as at 62, so as to engage the lugs 55, with which said feeddisk is provided. It will thus be apparent that motion will be conveyed from the feeddisk to the corn or cotton disk and that by operating the ratchet-wheel 39 the motion may be arrested and the feed stopped, such arresting and stoppage of the feed being accomplished while the planter is in motion by simply operating the clutch-rod 43, heretofore described, which will, through the medium of the clutch yoke, depress the lower clutch member or ratchet-wheel until it is out of engagement with its companion in the hopper.

The upper side of the corn or cotton-seed disk may be provided with a central concaved bearing-lug 63, and in the lug is stepped the lower cone-shaped end 64 of a vertical post 65, which depends from and may be formed as a part of a transverse bridge-bar 66. This bridge-bar is located across the upper end of the hopper and `is formed with slotted angular ends 66, which rest against the inner side of the hopper-wall, a pair of bolts 67 being passed through the slots mentioned and through corresponding circular bolt-holes in the hopper-wall and provided at their outer ends with win ged nuts 68. By running these nuts backward so as to slightly loosen the bolts it is obvious that the bridge-piece may be raised until the lower cone end of its post is out of engagement with the cavity of the lug 63 of the corn or cotton disk, and hence,

for instance, the cotton-disk may be removed and a corn-disk substituted, and thus the;

planter easily and quickly converted from a cotton to a corn planter, or vice versa.

Now to return to the motion-producing mechanism. Between the annular parallel beads formed on the upper and lower caps or sections 16 and 23 composing the gear-case is located an upper and a lower ring 65 and 66a, respectively designed to revolve or oscillate horizontally in contactwith each other and about the gear-case, these rings being conlined in position by means of the aforesaid beads with which the gear-case is provided. The upper ring is provided with a depending extension 66h, which bears on the lower ring and from which radiates an outwardly-disposed bored stud 67a, and the lower ring is provided with an upward extension 68,which bears against the upper ring and from which radiates outwardly a similar bored stud 69, the said studs being opposite the two side openings in the gear-case. studs is journaled a short radial axle 70, said axles being somewhat longer than the studs in which they are mounted. On the outer ends of the axles are mounted in any rigid manner ordinary covering-disks 72. rated lugs 7l may be formed on the studs 67"L and 69, and supported in an adjustable man- In each of these` Perfo-` ner thereon, by means of set-bolts 73, is a pair of scraper-blades 74. The blades are bent at their lower ends at 75, which bent portions are slotted, as at 76, whereby the blades may be adjusted with relation to the covering-disks. It will also be seen that radial movements of the covering-disks will cause similar movements upon the part of the scraper-blades, so that the relative adjustments between the blades and coveringdisks are maintained.

At the inner ends of the radial axles (which occur within the gear-case) are located and fixed small bevel-gears 77, which, as will be apparent, are in the same horizontal plane, but the axles differing slightly in length the gears are not in the same annular plane or radius. The gears are also of different size. The larger one meshes with and drives a similar bevel-gear 78, located on the operatingshaftwithin the lower half of the gear-case, and the smaller of these bevel-gears 77 meshes with and drives a larger opposing gear 7 9,. located in the upper half of the gear-case on the operating-shaft and slightly smaller than its companion 78. As a result of this system and proportioning of gearing the two covering-disks through their axles transmit motion at the same relative speed and in the same direction to the operating-shaft, so

that the latter is driven positively andthe strain is equally divided by the two sets of drivers.

-An angular horizontal frame 80 is located in rear of the hopper, the forwardly-projecting terminals of the frame resting on the horizontal lugs projecting from the hopper-bottom and lnay be secured in position by means of the same bolts that serve to secure the hopper-bottom to the main U-shaped yokeframe 9. A hand-lever Sl convenient to the operator is loosely clipped, as at S2, to the rear transverse portion of the frame and has its lower end inwardly bent or offset, so as to be in juxtaposition to the gear-case and the rings carried thereby. Each of these rings is provided with a bearing-pin 83, the upper one passing loosely through and beyond an elongated slot 84, formed in the hand-lever. At its lower end the hand-lever is provided with an opening S5, through whichpasses a bolt 8G, which projects radiallyfrom the opening or perforation formed in the depending half-round lug 22, that extends from the annular flange of the upper half or cap of the gear-case. its ends, so as to be fulcrumed on said bolt, and between the head of the bolt and the link there is coiled on the former a tensionspring 88. This link is provided with upper and lower elongated slots 89 and 90, respectively, the upper slot receiving the upper bearing-pin S3 or that of the upper ring, and the lower slot receiving the lower bearingpin 83 or that of the lower ring. At its extreme upper end the link is provided with a transverse slot 91, curved concentrieally with.

A link 87 is perforated between` IOO IIO

IZO

relation to the fulcrum-bolt 86 of the gearbox. An adj usting-bolt 92 passes through this slot and a coincident bolt-hole in the hand-lever.

It will be evident that by oscillating the 1ever, the bolt 86 as the fulcrum, the two rings on the gear-case will be caused t'o oseillate or partially rotate in opposite directions, this by reason of the intermediate fulcruming of the hand-lever on the bolt S6. This opposite rotary movement upon the part of the rings causes the covering-disks to gather or angle or separate, so that their angles are increased or diminished, and thus the machine will be caused to plant the desired depth. The covering-disks may be locked in any of their adjusted positions by means of an adjustingscrew 93, passed through the lever and the clip 82, said screw serving to clamp the clip upon the frame 80. Other means may readily be devised for accomplishing this locking of the parts. In fact slight modications in regard to the various details of the invention will readily suggest themselves, and for this reason I would have it understood at the outset that I do not contemplate conning my invention to the details herein shown and described, but maintain that I may vary the same to any extent and degree desired and which may be'within the knowledge of the skilled mechanic without departing from the spirit of my invention or sacrificing any of its numerous advantages.

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