SPECIFICATION forming part of Letters Patent No. 602,903, dated April 26, 1898. A li ation fil d May 21, 1897. $erial No. 637,639. (No model.)

To (all whom it may con-corn:

Be it known that I, Gnonen D. HAwoRTH, of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Corn-Planters, of which the following is a specification.

This invention is embodied in a complete modern corn-planter having mechanism for drilling the corn, mechanism for planting in check-rows, mechanism for dropping by foot or hand, automatic reeling mechanism, a marker to form impressions in the soil to guide the driver, &c., it relates to various details and peculiarities in connection with the different. features of the planter, it is exemplified in the structure hereinafter described, and it is defined in the appended claims.

In the drawings forming part of this specification, Figure 1 is a plan showing as well as can be illustrated in a single view the various parts combined in an operative planter. Fig. 2 is a plan of the wire-reeling mechan ism, showing the conditions under which the wire is guided to the extreme inner side of the reel.v Fig. 3 is a similar view showing the conditions under which the wire is guided to the extreme outer side of the reel. Fig. at is a side elevation of the wire-reeling mechanism. Figs. 5, 6, and 7 are details illustrative of the action of a f fictiondeveloper which forms a part of the reeling mechanism and possesses some novel characteristics that aid in efiecting one of the principal objects of such mechanism. Fig. 8 is a front elevation of the reeling mechanism. Fig. 9 is a plan showing the drilling mechanism in detail and also showing parts of the foot-drop mechanism. Fig. 10 is a plan showing the foot-drop mechanism in detail and also showing parts of the drilling mechanism. Figs. 11 and 12 are front elevations of details of the drilling mechanism. Figs. 13 and 14: are side elevations of details of the foot-drop and drilling mechanisms, illustrating certain cooperative peculiarities thereof. Fig. 15 is a side elevation of the mechanism used to lift the runner-frame. Fig. 16 is a representation of the under surface of a check-rower arm. Fig. 17 is a bottom view of a block or casting, one of which is located at each joint and at the swinging end of the check-rower arm. Fig. 18 is a side view of a joint-casting in connection with the bars of the arm and with the guide-rollers. Fig. 19 is a vertical section through a swingable draft-hitch, by means of which the side draft of the marker-bar may be automatically neutralized. Fig. 20'is a plan of the marker-bar and the side-draft neutralizer. Fig. 21 is a rear elevation of the marker-bar and its connections. Fig. 22 is a side view of the cut-01f plate of a seedbox, showing a knocker-finger thereon for dislodging corn from the seed-cells of a planterdisk. Fig. 23 shows a seed-disk in section and a knocker-finger in operative position with relation thereto. Figs. 24 and 25 are details illustrating the operation'of the knockerfinger. Fig. 26 is a plan of the under side of the cut-0d plate with the finger swung thereon. Fig. 27 is a plan of the under side of'the cut-off plate, the finger, and a seed-disk, all in operative correlation.

The type of planter shown in Fig. I of the drawings and in which the various improvements are in this instance embodied is that commonly known as the Haworth crosswire, but in most particulars the invention is independent of the general structure of the planter, and this particular style is shown merely as a preferred form, sufficient to enable persons skilled in the art to reduce the various details of the invention to practice and to apply them to any desired form of planter. *With this explanation it maybe stated that the planter-frame comprises an axle-bar 10, on which carrying-wheels 3 are mounted; a rear cross-bar 11, with which covering-wheels 4 are connected,an intermediate cross-bar 9, which connects the seedboXes 2, and a front cross-bar 8, with which the front ends of runners 1 connect. A tongue 5 connects with the front cross-bar and with the intermediate cross-bar9. Bars 80 extend obliquely upward from the cross-bar 9 over the wheel-frame, from which they are supported at their rear ends. A seat 6 iscarried on bar 7, which forms a rearward extension of bars 80. The seedbcxes are connected with the axle-bar in a mannerpermittingindependent vertical motion of the runner-frame and the wheel-frame, and the different parts are suitably braced.

One feature of the invention relates to the reeling mechanism for the wire, and it resides partly in provision whereby the wire may be made to actuate the planting mechanism while being reeled and unreeled and partly in means for disposing the wire evenly on the reel.

A reel 18 is made of any desired form and proportion, and it is mounted on a shaft 19 in a manner to slide lengthwise thereon and partake of the rotary motion thereof. The connection between the reel and its shaft is typified by a feather and slot, but it preferably consists of a finger 30, fixed onto the end of the shaft outside the reel and extended parallel with the shaft into sliding engagement with an arm or spoke of the reel-frame. The shaft 19 is journaled in asleeve20, which is carried on an approximately vertical rocking bar 23. The rocking bar is connected with a cap 41, which fits loosely over and is detachably secured to a wheel-spindle 42. (Shown in Fig. 4.) Abrace-bar 37 connects with the upper end of a continuation of the reel-carryin g bar 23. It extends inward over a wheel of the planter and downward to a hook 39 on the axle-bar, and it has on its inner end an eye 38, which detachably engages the hook on the axle-bar. Another bracebar 28 connects swingably with the sleeve 20, and it extends forward and connects detachably with a check-rower arm. The reel is provided on each side with a circumferentially-grooved collar 36, (see Fig. 3,) by means of which the reel may be shifted sidewise while turning. Straps 25 are bent at their outer ends to engage the groove of collar 36. They extend one on each side of the upper extension of bar 23 and the upper portion of the brace-bar 37, and they connect at their inner terminations with a lever 40 on brace-bar 37. The lever is connected pivotally with the brace-bar in position to be readily accessible to the driver on the planterseat, and it provides means whereby the reel may be shifted inward or outward on its shaft, and the entire reel-frame may be rocked forward and backward. To hold the hooked ends 27 of straps 25 into engagement with the groove of collar 36, a groove or slot is formed by means of aparallel rod 24 on sleeve 20, and a bolt 26 extends from one strap to the other through the slot or space between the rod and the sleeve.

The mechanism employed to transmit motion from a planter-wheel to the reel in reeling the wire and to retard the reel in unreeling is the same as that described by me in Letters Patentof the United States No. 534,474, issued February 19, 1895, except for details in the friction-developer, which enable the reel to be used on either side of the planter, and such mechanism comprises a sprocket- Wheel 29, connected with a planter-wheel 3, a pulley 21 on the inner end of the reel-shaft 19, a chain 22, driven by the sprocket-wheel and running over the pulley, an arm 3l,adapted to bear against the chain in reeling and against the pulley in unreeling, and a spring k evenly distribute the wire on the reel.

to impart yielding pressure to the arm. The spring is in housing 32, which is connected with the arm by means of a detachable link 33, and its extended end 31, or the extended end of the rod that bears against it, connects with a clamp-link 35, which engages the lower end of bar 23 and firmly engages such bar by automatic cramping action when the spring exerts a pull on its extended end.

The arm is swungloosely on a pin 51,which extends inward from upward continuation 23 of the reel-supporting bar 23, and it has on opposite sides chain-bearing surfaces 31", a central pulley-engaging finger 31, and a perforated head 31, with which the spring engages. When the wire is reeled up with the reel located on one side of the planter, one bearing-surface 31 is made to engage the chain. When the wire is reeled from the other side of the planter, the other bearing-surface engages the chain, and the central finger 31 engages the periphery of the pulley whenever the wire is unreeled from either side of the planter. WVhile the wire is being reeled, the friction-developing arm occupies the position with relation to the pulley shown in Fig. 7, and in preparing to unreel the arm is detached from the spring, swung upward, as suggested in dotted lines in Fig. 5, the finger 3l is passed overa flange of the pulley by sliding the arm on pin 51, the arm is lowered until the finger bears against the concavity of the pulley, and the spring is reconnected with the arm.

The check-rower arms are connected with the planter in a manner permitting a limited amount of horizontal swing across the winding-surface of the reel, and they are in horizontal alinement with the under side of such surface. In other words, the under surface of the reel is approximately in horizontal alinement with a check-rower arm when operatively mounted, and the arm has a limited amount of swing across the face of the reel. The brace-bar 28 performs the double func tion of sustaining the reel-frame from the check-row arm and of swinging the checkrow arm horizontally when the reel-frame is rocked vertically.

In unreeling the wire the chain 22 is removed, the finger of the friction-developer is made to engage the pulley, as hereinbefore described, the spring is adjusted to develop the required degree of friction, the wire is run off the reel and through the check-row mechanism, and the dropping mechanism of the planter is actuated as the wire is laid out. In reeling the wire the chain is replaced, the friction developer is made to engage the chain, the wire is fed to the reel through the check-row mechanism, thereby actuating the drop-plates of the planter, and the handle i0 is manipulated by the driver in a manner to The reel is shifted lengthwise of its shaft in order to obtain a part of the motion necessary to distribute the wire over all portions of the periphery of the reel, and the residue of such motion is obtained by swinging the end of the check-row arm across the face of the reel.

In the first instance the lever 40 is swung inward and outward sidewise of the planter.

In the second instance the lever and the entire reel-frame are swung forward and backward lengthwise of the planter, and the complete wire-guiding action is a complex commingling of the two sets of motions, each of which is auxiliary and complementary of the other. It is diflicult to get suflicient swing in the checlnrow arm to carry the wire from side to side of the reel. The reel cannot be shifted out-ward sufficiently far to carry the wire to its extreme inner side without developing undesirable strain on the reel-frame, and so the two mechanisms complement one the other.

A prominent function of the reel that of actuating the plan ting mechanism while reeling and unreeling-depends more on general peculiarities of the reel and the check-row mechanism and the correlation thereof than upon the specific characteristics of the reel already described and those of the checkrow mechanism, which will form the subject for a subsequent description. The reel may be driven and controlled by means substantially different from those disclosed and the wire maybe distributed by difierent means, or not at all, without impairing the identity of the broad idea in volved in this feature of the invention and which is embodied in such correlation of planter, reel, and check-row mechanism that the reel may be used on either side of the planter interchangeably, and the check-row mechanism may act as a guide to supply the wire to the reel in act of reeling and receive it from the reel in act of unreelin g. To provide for these requirements specifically, a hook 39 is attached, one to each side of the plantenframe, in position to engage the eye 38 of brace-bar 37. The brace-bar 28 is swingable on the sleeve and adapted to engage with either of the check-row'arms. The cap 41 is adapted to engage either of the wheelspindles, and the frictioirdeveloper arm 31 may be used with the reel in either position. Furthermore, the check-row mechanism bears such relation to the reel that the wire may be passed through the mechanism without materially affecting the operation of the reel, and the specific peculiarities of such checkrow mechanism will hereinafter appear.

The particular checlcrow mechanism shown and described is that known as cross-wire; but it is obviously not impracticable to apply the general idea of the simultaneous reeling and planting or unreeling and planting to side-wire planters either by guiding the wire across the planter or otherwise directing it to the check-row mechanism and from there to the reel.

The reel-spider is capable of translatory transposition from one side of the planter to the other, and so the wire on the reel always bears the proper relation to the check-row mechanism, no matter on which side the reel is mounted. If this were not so, if the reel required turning in shifting it from one side of the planter to the other disarrangement of the wire with relation to the check-row mechanism would result to an extent to make it impossible to efiect the desired result.

The check-row arms shown in this instance possess the not unusual peculiarity of swinging forward to receive the wire and swinging backward to discharge it, and in addition they have some novel characteristics which increase their utility. They each consist of abracket 43, which is adapted to be connected with the planter somewhat as shown in the drawings and which has sidewise-projecting lugs 43. (See Fig. 16.) A casting or block 47 is pivoted on the upper side of the bracket on a bolt, as 87, which extends through the bracket and the block, and it has downwardextending studs 47, which engage the lugs of the bracket and limit its swing. Underneath the bracket an end of a bar 44 is swung on bolt 87, and above the bracket a bar 45 sets rigidly in the block and extends in the same general direction as bar 44. The upper bar 45 is shorter than the lower bar, and it terminates fixedly in another block 47, which is essentially the same as that hereinbefore described. Another bolt extends through the second block, through the lower bar 44, the upper bar 45, and through an end of a third bar 46, which is interposed between bars 44 and 45 and which extends inward some distance beyond the second block. The block at the conjunction of bars 44 and 45 with bars 46 also has downward-extending studs 47, and these engage the inward-extending end of bar 46 and limit the swing of such bar. The bars 44 and 45 form a truss member having a limited amount of horizontal swing, and the extending end 44"- of bar 44 forms a stiifening-support, on which bar 46 swings to the extent permitted by the studs on the block with which it is pivotally connected. A third block of a character substantially identical with those hereinbefore described, except that the studs 47 may be omitted, is fixed onto the outer or swinging end of bar 46, and each of the blocks has a pair of upward-extending rollers 48, between which the wire 52 runs. Each pair of rollers has a guard-finger 49, which extends from the upper end' of one roller across the space between the pair and terminates adjacent to, but not contiguous with, the opposite roller.

The guards, disposed in the manner shown and described, hold the wire between the rollers while the planter is operating and provide for raisin g the wire out of the arms whenever necessity for detachment arises. Further utility of the arms resides in the specific provision for limiting the swing of the different members, in the truss construction of the inner member, and in the means employed to sustain the outer member.

The check-rowmechanism consists of the ICC IIS

swingable arms, forked levers 50, pivotally connected with the planter,one adj acent' to each arm and in position to receive the checkrow wire, a rock-plate 53, with which the forked levers connect through rods 58and 59, a forked rock-arm 56, which is actuated by the rock-plate, and a rod 83, connecting the rock-arm with the shake-bar 12 of the planter.

The foot-drop mechanism comprises a rockframe 60, pivoted centrally at 61 on bars 80 of the planter and having pedal extensions 62 and 63, one to the right of and behind the pivot and one to the left of and in front of the pivot. The rock-frame has an upward extension 64, from which a rod 82'extends to an arm of rockplate 53. When the foot-drop is used, the rods 58 and 59' are disconnected from the rock-plate, rod 82 is connected therewith, and motion is imparted to the shakebar through the rod 82, the rock-plate 53, the

. rock-arm 56, and the rod 33 whenever frame j ections.

is oscillated by the feet of the driver. I

The drillingmechanism consists of a shaft wheel 105 (seen only in Fig. 1) on its outer end. The sprocket-wheel is adapted to be driven with a chain run from the reel-drivin g sprocket-wheel 29, and so the shaft when operated receives motion from aplanter-wheel; Theinner end of the drill-shaft has clutch projections, as 68. A crank-arm 67 is mounted slidably on the end of the shaft, and it has recesses adapted to receive the clutch pro- A pitman 69 is connected with the swinging end of the crank-arm, and its extended end is recesses sidewise to engage a vertical bearing of an L-lever 7 O. The L- lever is pivoted on a bracket-casting 65,which forms a bearing for one end of the drill-shaft. One of its ends is diverted downward and then extended horizontally to form the pitman-support 71 and provide a vertical engagement bearing for the recess of the pit man, and a rod 72 connects its other end with the shake-bar of the planter. As the drill should not operate when the runners of the planter are out of the ground provision is made to disengage the drill-shaft from .the shake-bar when the runners are raised. This provision consists of the slidable crank-arm, which forms a clutch member cooperative with the projections on the shaft, a U -bar 73, connected with the crank-arm,a vertical rockarm 74 in line with the shaft, a link 75, connecting the rock-arm with the U-bar, and a finger 77, adapted to rock the arm 74 as the runner-frame is raised and thereby carry the crank-arm out of engagement with the projections on the shaft. The rock-arm 74 has a slot 76, which extends obliquely upward when the crank-arm is in clutch with the shaft, One end of finger 77 extends into the slot of the rock-arm, and the other end thereof is connected rigidly with the rock-frame of the foot-drop movement. I The rock-frame 60 has a cross-bar 81, which extends below the seat- "the clutch into engagement.

brace bars 80, as shown in Figs. 9 and 10.

When the runners of the planter are in the ground, the conditions of the clutch-actuating mechanism are as shown in Figs. 11 and 13, the end of the finger being in the lower end of the slot of the rock-arm and the crankarm being in clutch with" the shaft. As the runners are raised the bars 80 swing toward the horizontal, the cross-bar 81 of the footdrop frame is depressed, the extended end of thefinger is correspondingly raised, the rockarm 74 is swung away from the end of the shaft by the action of the finger in the inclined slot, and the crank-arm is drawn from contact with the projections of the shaft. (See Figs. 12 and 14.) When the runners are lowered, the clutch recesses of the crank-arm may not coincide with the projections on the shaft, and in that case the finger will remain in the upper portion of the slot'until motion of the shaft brings the clutch members into coincidence, when action of gravity, aided, if necessary, by a spring, as 79, will draw the finger downward, rock the arm 74, and force To provide for the motion in the crank-arm lengthwise of the shaft, the pitman has the lever-engaging recess formed in one of its sides. Such recess extends parallel with the endwise motion of the crank-arm,'and the L-lever has the horizontal extension7l, on which the recessed end of the pitman may slide. WVhen the crank-arm is moved lengthwise of the shaft, the pitman moves correspondingly on the extension of the L-lever, and the recess of the pitman is sufficiently deep to permit such motion without disengaging the pitman from the L-lever. When the drill mechanism is used, rod 83 of the check-row movement is disconnected from the shake-bar and motion is imparted to the dropping mechanism through the sprocket-gearing, the shaft, the crankarm, the pitman, the L-lever, the rod 72, and the shake-bar. When the foot-drop mechanism is used, the finger 77 is detached from the rock-frame 60.

In using cross-wire planters the wire is taken up on one side of the planter and run 01f from the opposite side. The side from which the wire is run off is the side from which the marker-bar extends. The checkrow mechanism is in front of the marker-bar. Ordinary marker-bars extend beneath the wire, and turns are made at the ends of the field without disconnecting the wire from the planter. This condition of affairs has heretofore required the marker-bar to be detached from the planter prior to turning around and to be reattached afterward, an operation that has objectionable features, and it is the purpose of one feature of this invention to overcome such objections. To this end the marker-bar is made in two parts 95 and 89, pivotally connected at their conjoining ends. The part 95 has a bracket 96 which joins with the planter-frame below the seat thereof in a manner permitting universal swing, but preeluding rotation of the bar. The part 89 car-. riesa marker $8 on its outer end, and its inner end lies alongside the outer end of part 95 and is pivotally joined thereto by a horizontal bolt 90. The extreme inner portion of part 89 extends past bolt 90, and it has a V-shaped recess 91 out into its inner surface. A leveryoke 92 is pivoted on the outer end of part 95 of the marker-bar with its ends in position to engage the recess 91 of the other part of the bar. The yoke is U-shaped, it embraces the bar top and bottom, and its ends extend rearward past the rear surface of part 95. A line 93 connects with the looped end of the yoke or U-bar 92, and with the planter-seat or seat-bar it tends to hold the U-bar in engagement with the recess of part 89, and it provides means for raising the marker-bar. This construction enables the part 95 to extend in an approximately horizontal direction at an elevation sufficiently great to permit passage of the check-row wire beneath it, and when the planter reaches an end of the field the entire marker-bar may be raised preparatory to turning and afterward be laid down onthe opposite side of the planter. To facilitate this operation, a hook 94 is fastened to line 93 between the ends thereof, and the bar is held raised while the planter is turning by engaging the hook with an eye formed on a side of the drivers seat, as shown in broken lines in Fig. 21. When the planter is turned around, the marker'bar is swung over to the opposite'side and the U-bar is disconnected from the notch and reconnected with the other end in engagement therewith, which operation deflects the bar in the proper direction to ride over the wire, and the planting proceeds.

create side draft.

The marker 88 has a draft-line 17, which extends obliquely forward and connects with some convenient portion of the planter-frame, preferably with an equalizing draft -hitch,

which forms a feature of the invention and which will now be described as follows:

The general tendency of the marker is to is unfavorable to straight driving and straight cross-rows. To, overcome the side draft, I provide a swinging draft-hitch for the team and connect the draft-line of the marker-bar with the draft-hitch in a manner to cause the pull of the marker-bar line to shift the center This may be done in different ways, and the specific means herein shown are representative merely of the general idea.

A clevis 14 is pivotally connected at its rear endwith the tongue of the planter by means of vertical bolt 15, and the doubletree 13 is swung pivotally in'its front end on vertical belt 145*.) An eye 16 is swiveled in the front end of the clevis, and with such eye the forward end of the draft-line 17 of the marker connects. The rearward pull of the markerbar carries the draft-hitch to one side to an extent exactly sutficient to shift the line of The tendency varies with the obstructions encountered, and the result draft to the center of resistance, variations in the line of draft occur instantaneously and automatically, as demand arises, and so the planter may be drawn forward in a straight line with one runner as well advanced as the other and without distressing the team by variable side draft. The swiveled eye enables the marker-bar to be swung from side to side of the planter without changing the relation of the draft-line of the marker-bar to the clevis of the draft-hitch.

This feature of the invention is useful in other environments than those -described as, for instance, in a mower or reaper to neutralize the side draft of the sickle-bar.

Another feature of the invention relates to the seed-dropping mechanism, and it resides in a finger which hangs normally in a seedcell, is carried upward out of the cell by the motion of the seed-disk, strikes a surface at the termination of its upward throw and rebounds forcibly in to the next succeeding cell. In this instance. the finger 100 forms a con-' tinuation of shaft 98,whicli is pivoted in the cut-off plate 97. It occupies a position in the cut-off space above the seed-disk 101, and it tends to hang downward into a cell 102. The shaft 98 has a knocker extension 99 on its outer end,which also tends to hang downward and away from the under surface of plate 97. When the seed-disk is moved in act of planting, its motion is rapid. A side of a cell strikes the finger and forces it sharply upward until the knocker' strikes plate 97, as shown in Fig. 24, and develops a rebound that carries the finger forcibly back into the next succeeding cell and dislodges the grain, if need be, as suggested in Fig. 25. To increase the force with which the finger will enter a cell, an elastic hard-rubber cushion may be downward and sidewise to brackets 84E of the runner-frame. When the lifting mechanism is operated through hand-lever 86 or other wise, the stress is applied equally to both sides of the runner-frame, and such frame is raised or lowered without developing side tilt therein, and when the planter is in operation the obliquestraps prevent one runner from entering the ground to a greater depth than the other and so overcome an objection common to wire-actuated planters.
