PLANTER.

SPECIFICATION forming part of Letters Patent No. 594,037, dated November, 1897.

Application tiled March 28, 1896.

Serial No. 585,271. (No model.)

T altrui/tom it may concern Be it known that we, JOHN M. SCOBEE and EDMOND SILAs BUSH, citizens of the United States, residing at Shelbyville, in the county of Shelby and State of Kentucky, have iii-- vented a new and useful Planter, of which the following is a specification. p

This invention relates to certain new and useful improvementsin that class of planters :o designed for sowing seed in check-rows and which have combined therewith marking devices forindicating the hills, thereby enabling the planting to be effected in check-rows.

One of the principal objects in view is to r 5 provide for disconnecting the seed-dropping mechanism from the actuating mechanism of the planter, so that when required the planting may be effected by hand or the seed dropped by the intervention of the ordinary 2o check-line provisions. l

A further object of the improvement is to devise a novel combinationof elements Whereby the marking and the seed-dropping mechanisms can be thrown out of gear and the Y marker moved forward or backward to aline the machine, whereby the planting will be effected in parallel rows, which is of advantage in dropping corn and other seed usually planted in parallel longitudinal and transverse lines.

A still further object of the invention is to provide actuating mechanism for the seeddropping plates which will be positive in its action, insure the registry of the openings in the dropping-plates with the openings in the beds leading to the grain-tubes, and which will prevent the dropping-plates moving too far forward when impelled by the `reciprocating pawls.

4o Other objects and advantages are contemplated and will appear as the nature of the improvement is understood; and to this end the invention consists in certain details of construction and novel features and combinations of parts, which hereinafter will be more particularly set forth, illustrated, and nally embodied in the appended claims.

Referring to the drawings, Figure l is a top plan view of a planter constructed in ac- 5o cox-dance with the principles of this invention for attaining the object thereof.

Fig. 16 is a detail View7 partly in section, of a hinge connection between the draft and main frames.'

Corresponding and like parts are referred 9c to in the following description and indicated in the several views of the drawings by the same,reference-characters. l

The draft or runner frame 1 and the main Vor wheel frame 2 are pivotally connected to- 95 gether, so as to admit of the frames moving relatively to adapt themselves to the nature of the ground or to admit of the draft-frame being adjusted vertically to lift the runners 3 from the ground or cause them to penetrate roo the soil to a greater or less depth, according to the nature of the land and the character of the seed to be planted. Brackets 4 are secured to the rear bar 5 of the draft-frame and have tubular bearings at their upper ends, and irons 6, fastened to the front ends of the longitudinal bars 7 of the main frame, have eyes at their front ends which receive the inwardly-extending ends of the tubular bearings of the brackets et, and these

parts

4 and 6 form the hinge or pivotal connections between the two frames. The actuating rod or bar 8 operates through the tubular bearings of the brackets it and is in line with the axis about which the main and draft frames tilt.

The draft or runner frame comprises a front bar 9, a rear bar 5,'oppositely-inclined braces 10, grain-spouts 10i, and runners 3. The pole or tongue 11 is secured to the bars `5 and i), and its rear end projects a short distance beyond the bar 5 and is connected by links 12 with the front end of a lever 13, fulcrumed upon an intermediate bar of the main frame, and by means of which the draft frame can be raised or lowered to bring the runners to the required elevation either to throw them out of the ground or to enter the latter to a greater or less depth.

The main or wheel frame comprises longitudinal side bars 7, an intermediate longitudinal bar 14, front and rear bars 15 and 1G, and an intermediate cross-bar 17, the several bars being connected together in any substantial manner. The axle 1S is journaled in bearings intermediate the ends of the main frame, and the ground or drive wheels 19 are loosely mounted upon the spindles formed at the ends of the axle, and their rims are broadfaced and concaved and track in the path of the runners, so as to cover the seed and compress the soil thereon. Toothed rims or disks 2O are applied to or formed with the hub of the ground or drive wheels, so as to rotate with the latter and form parts of a clutch interposed between the marker and the drivewheels.

The markers 21, located near the ends of the axle, consist of bars mounted midway of their ends upon the axle, so as to rotate therewith, the ends of these bars being expanded and bent at right angles to indent the ground to one side of the hill in which the grain is planted. Inwardly-extending sleeves 22 receive the axle and are formed with or applied' to the markers and form guides for

collars

23 and 24, connected by means of radius-arms 25 with the terminals of a rod or bar 2G, extending transversely of the frame. The collar 2lC has an annular flange 27 at the end adjacent to the contiguous marker to engage with the inner ends ot` the clutch-levers 2S, so as to move them away from the adjacent marker when it is required to throw the latter out of gear. A stop 29 is adjustably mounted on the transverse rod 2G, being held thereon by a binding-screw 30, and is adapted to be engaged by the vertical arm of a bellcrank lever 31 when it is required to move the rod 2G longitudinally to throw the marker and the seed-droppin g mechanism out of gear. The bellcrank lever 31 is fulerumed to a bracket 32, secured to the side of the intermediate longitudinal bar let, and its horizontal member is expanded, forming a foot-rest 33, upon which the foot obtains a purchase when it is required to actuate the said lever 31.

Theclutch-levers 2S are similarly formed and have cross-bars at their outer ends, bent to form parallel ears, which have pivotal connection with the marker near its outer end, the inner ends of the levers being clawshaped to embrace the sides of the collar 24: and engage with its outer flange 27. Lugs 34: are formed on the inner sides of the clutch-levers 2S and operate through openings in the marker and are adapted to engage with the teeth of the adjacent toothed rim or disk 20, so as to cause the drive-wheel and marker to rotate when .the parts are in mesh. A spring 35, formed of wire of proper gage and bent into the form of an oblong frame, has its ends en gagin g with the clutch-levers 2S between their extremities and has its middle portion deflected and engaged by projections 3G at the edges of the marker. These projections 36 are preferably machine-screws, and the side members of the spring-frame have eyes midway of their ends, through which the projections 36 extend to secure the spring in place. The clutch-levers 37, near the opposite end of the axle, are fulcrumed between their ends to the marker, and their inner ends are claw-shaped to span the sides of the collar 23, and their outer ends have lugs 3S, which operate through openings in the adjacent marker and engage with thc teeth of the contiguous toothed rim or disk 20, so as to lock the proximate drive-wheel with the marker when the latter is in gear. A spring 39, similar in construction to the spring 35 and having connection with the marker by projections 40, substantially the same as the projections 3G, has its ends engaging with the outer portions of the clutch-levers 37, so as to press the lugs 38 through the openings in the marker and into engagement with the adjacent toothed rim. When it is required to throw the marker, comprising the two bars 21, out of gear, the outer end of the horizontal portion of the bell-crank lever 31 is pressed upon, thereby imparting an endwise movement to the rod or bar 2G, and the collar 23, bearing against the inner ends of the clutch levers 37, and the tlange 27 of thc collar 24, pressing against the inner ends of the clutchlevers 2S,cause the said clutch-levers to move,

so as to throw the l'ugs carried thereby out of engagement with the toothed rims or disks 20, thereby attaining the desired end. Upon ren moving the pressure from the lever 31 the

springs

35 and 39, previouslycompressed, will regain themselves and throw the marker into gear and return the operating parts to a normal position.

The lever 13 is t'ulerumed to a bracket 41, and its rear end extends over the horizontal member of the bell-crank lever 31 and terminates in a cross-bar 42, which is curved upwardly at its ends to receive the feet of IOC IIO

the driver when it is required to elevate the draft-frame. If it be required to throw the planter out of gear simultaneously-with the lifting of the draft-frame, the rear end of the lever 13 is depressed to its full limit, thereby bringing it in engagement with the horizontal portion of the said lever 31 and depressingit, thereby attaining the desired result. A bar 43 extends about at right angles from the lever 13 ina vertical direction andis strengthened by a curved brace 44, and an arm 45 projects forwardly from the upper end of the bar 43 and terminates in a cross-bar46, whose end portions form a foot-rest upon opposite sides of the arm 45, corresponding to the end portions of the cross-bar 42, and which receive the feet of the driver when the latter desires to apply force to cause the runners to enter the ground to the required depth.

A hand-lever 47 is mounted upon* the piv- 'v otal connection between the lever 13 and the bracket 41 and is supplied with the usual hand-latch 48 and locking-bolt to engage with the teeth of a notched segment 49, forminga part of the bracket 41 or applied thereto, and this hand-lever has a Vdog 50, pivoted to a side thereof and adapted to engage with the upper end of the bar 43, thereby locking the foot-lever 13 and the hand-lever 47 and causing them to operate practically as one part, whereby the hand-latch 48 and the notched segment 49 can be resorted to for holding the lever 13 and the draft-frame in the adjusted position. The dog 50 has its vertical extension bent at right angles, forming a projection 5l, to be grasped by the hand or engaged by the foot when it is required to operate the dog to throw it into or out of operative relalation. The upper end of the bar 43 is constructed to be engaged by the hooked end of the dog 50 and has a lateral extension 52 proj ectin g over the notched segment 49, to be engaged by the hand-lever 47 when the latter is moved forward to lower the draft-frame. The seat 53 is located upon the rear portion of the main frame, and the various levers are within convenient reach thereof, and this seat is supported upon rods 54, extending upwardly from the main frame and converging at their top ends, where they are joined to the seat in any 'convenient way.

A longitudinal shaft 55 is j ournaled in bearings provided on the front bar 15 and the intermediate cross-bar 17, and a gear-wheel 56, secured to the rear end thereof, meshes with a companion gear-wheel 57, keyed upon the axle 18, and by this means motion is transmitted from the axle to the shaft 55. A

ratchet-wheel 58 is formed with or secured to the gear-wheel 57, and its teeth, which have the edges oppositely inclined, are adapted to be engaged by a double-ended pawl 59, having` pivotal connection with a hand-lever 60, fulcrumed upon the axle 18, said pawl being adapted to be reversed to cause eitherof its active ends to engage with the ratchet-wheel, so as to move the axle 18 either forwardly or rearwardly to accelerate or retard the movement of the marker. marker being behind it is thrown out of gear and moved forward to catch up and cause the planting to be effected in straight rows across the field, but should the marker be ahead it can be thrown out of gear by operating the foot-lever 31, as previously described, thereby admitting of the proper timing of the planting andthe marking mechanisms. It will be understood that when the hand-lever 60 is required for service the marker must be thrown out of gear. Under normal conditions the hand-lever 60 is out of engagement with the ratchet-wheel 58, the pawl 59 engaging with either the cross-bar 17 or the rod 26, by means of which it is held away from the teeth of the ratchet-wheel. A short curved bar 61 is attached to the hand-lever 60 and extends in the front and in the rear thereof and engages at its ends with the

parts

17 and 26 to support the lever when the latter is not required for immediate use. A lateral brace 62 is secured to the hand-lever 60 and extends over the ratchet and gear-wheels 58 and 57 and receives the axle 18 and serves to strengthen and brace the part 60, as will be readily understood. An eccentric 63 is attached to the front end of the shaft 55 and has a segmental flange 64 formed with or applied thereto, said segmental flange being concentric with'the shaft 55 and acting in the capacity of a retainer toY hold the reciprocating plate 65 during the time that the eccentric is compressing the springs employed for impelling the plate when the latter is released from the action of the segmental flange 64. The plate 65 has forwardly-extending arms 66, which receive the dropping rod or bar 8 and which are adapted to engage with adjustable stops 67 on the said rod 8. This plate is of open or skeleton form, and its rear bar is pivoted at one end and secured at its opposite end by a pin or machinescrew 68 and is formed with an elongated slot 69, through which the front portion of the shaft 55 passes. Stops 70 project forwardly from the rear portion of the frame and are adapted to be alternately engaged by the segmental flange 64, so as to retain the plate against movement during the interim ofy storing force by compressing the .springs 7l, by means of which the plate is moved when released from the part 64. A pair of lugs 72 are formed upon the top and the bottom sides of the plate 65 near its front end, and rods 73 are mounted in alining openings formed in the lugs. These rods 73 have cross-heads 74 at one end and are placed so that the crossheads are oppositely disposed-that is, with the cross-head of one rod near one end of the plate and the cross-head of the other rod near the opposite end of the said plate. ends of the cross-heads project across the path of the eccentric 63 and are alternately engaged thereby. A spring 71 is mounted upon each rod 73 and is confined between a lug 72 and a nut 75, mounted upon a threaded In the event of the The rear y IOO IIO y portion of the rod, and by a proper adjustment of the nuts the springs 7l can have their tension varied. The segmental iiange Gi is less than a half-circle and is disposed with reference to the eccentric and the cross heads 7 4, so as to retard the movement of the plate 65 until one or the other of the springs 71 is fully or nearly compressed before releasing` the plate to enable it to be moved by means of the compressed spring regaining itself.

The hoppers or seedboxes 76 are mounted upon the end portions of the rear bar 5, and their lower ends are closed by metal plates 77, which are retained in position by having one end engaging with pins 78 and the opposite end pressed upon by a cam-fastener 79. A circumferential slot S0 is formed in the plate 77 and registers with the circular series of openings 8l in the seed-dropping plate 82, which is j ournaled upon a pin projecting ver tically from the bed 83, secured to the bar 5. This bed S3 is recessed in its top side to receive the dropping-plate 82 and admit of the pawls Si and S5 alternately engaging with spurs 8G, projecting from the edge of the droppingplate, which is circular in form. A housing S7 is secured to the plate 77 at one end of the circumferential slot and incloses a pivoted clearer SS, which is disposed to travel upon the seed-dropping plate and remove the surplus grain therefrom. A spring 89, located within the housing S7, exerts a pressure upon the clearer S8 to hold its active end in engagement with the seed-dropping plate to eifect the desired result. This spring 89 is sufiiciently weak to yield and to prevent injurious contact of the grain with the clearer 8S, thereby admitting of a projecting portion of a seed riding beneath the clearer in the event of the latter being incapable of disengaging or dislodging the projecting grain.

The dropping rod or bar 8 is formed in sections which are coupled together by means of a pivoted joint 90, and the outer end of each section has formed therewith a crosshead 91,

having parallel arms 92 and an intermediate arm 93, the latter having a pendent lug 94 to engage with a short arm 05 of an elbow-detent 9G, which is pivoted to the bar 5 adjacent to the bed S3. An arched frame 97, pivoted at its lower end to the bar 5, is formed with ears 9S near the upper ends of its side members and has pivotal connection with the arms 92 by means of a pin 99, which latter passes through transversely alining openings in the arms 92, ears 98, and side members of the arched frame 97. The pawls 84: and have pivotal connection with the arched frame and arms 92, and are mounted upon the pin 99 and have their pivotal ends fitted in the space formed between the ears 98 and the adjacent sides of the arched frame. rlhe pawl S4 is essentially a push-pawl and the pawl S5 is a pull-pawl, since the former rotates the seed-dropping plate by pushing against the spurs SG and the latter effects the same result by pulling upon the said spurs. The pawls are disposed to alternately engage with the spurs SG, so that when the one is returning to an operative position the other is moving forward and operating the seed-dropping plate, as will be readily understood. The elbow-detent 96 has its long arm 100 provided with an adjustable stop 101 in the form of a set-screw which operates in a threaded opening provided in the terminal portion of the said arm, and its short arm 95 projects across the path of and is adapted to be engaged by the pendent lug 94. Vhen the rod or bar 8 moves forward, the pawl 84C will engage with a spur 8G and turn the seed-dropping plate a distance corresponding to the space between the openings S1, formed in the said plate, and when the pawl 811 reaches the limit of its forward movement the end of the intermediate or detent arm 93 will engage with a spur of the dropping-plate and hold the latter in position with an opening S1 in register with an opening 102 in the bed 83, so that the grain will drop through the latter opening into a tube 103 and from thence into the grain-spout 104: at the rear end of a runner. lVhen the part S is withdrawn or moves in an opposite direction, the hooked end of the pawl S5 will engage with a spur S6 and rotate the seed-dropping plate, so as to bring the next opening of the series of openings 8l into position for dropping its charge, and when the pawl 85 reaches the limit of its active or forward stroke the pendent lug 94 will IOO engage with the short arm 95 of the elbowdetent 9G and cause the terminal portion of the long arm thereof to engage with a spur S0 and hold the seed-dropping plate in proper position.

By providing the adjustable stop 101 provision is had for taking up wear and for adj usting the parts to allow for any deficiencies in workmanship, so that the movement of the seed-dropping plate may be checked at the proper time to effect registry of the

openings

81 and 102. The arched frame 97 serves to support the outer end of the rod or bar S and the parts attached thereto and obviates the friction incident to the sliding of one part upon another, thereby reducing the friction to a minimum and transferring the same to the pivotal connection between the said arched frame and the parts 5 and S. An opening 105 is provided in the cross-head 91 and receives the lower end of a lever 106, which is adapted to be removably attached to the inner side of a hopper when it is required to operate the dropping rod or bar 8 by hand. This lever has lateral trunnions 107, which obtain bearings in notched lugs 10S, secured to the said hopper. A seat 109 is fastened to a standard 110, attached to the bar 5, and the operator perches upon this seat when operating the lever 10G. The rod or bar 8 obtains bearings in the side members of the seat-standard 110, and the latter is strengthened by a brace 111.

IIO

The grain-spout 1G4, formed at the rear end of a runner 3, is contracted at its lower end and is divided into vertical channels by a pivoted cut-off 112, which terminates at its upper end just below the tube 103 and is provided with an upwardly-extending arm 113, which is connected by means of a link 114 with the pin 99, whereby the cut-off is vibrated at each movement of the rod or bar 8. The function of this cut-oft is to prevent the escape of the grain from the channels formed on opposite sides thereof until the cut-off is actuated. By this means accuracy in the planting of the grain is attained. The grain dropped into one channel passes to the lower end thereof, and is retained in the said channel until the cut-off-is operated, when the grain being inclose proximity to the ground will instantly drop into the required position, thereby insuring correctness in the planting, provided the dropping mechanism is propcrly timed. Y

A rod or shaft 115 is journaled to the rear end of the main frame and is supplied with scraper-blades 116 to remove trash, earth, and foreign matter from the rims of the drivewheels, and a radins-bar 117, vsecured to the rod 115, is connected byarod 11S with afootlever 120, pivoted to a side of a bar 7 and having an expanded portion 119 to receive the foot when it is required to throw the scraperblades into working position.

It will be understood that each hopper or seedbox will be provided with a bed, a bottom plate7 and seed-dropping mechanism, the cooperating parts foreach being constructed substantially as herein set forth.

The invention in its entirety or in part may be applied in the construction of seed-planting machinery. Hence it is obvious that in adapting the invention to a particular requirement various changes in the form, proportion,
