'CORN-PLANTER.

SPECIFICATION formingpart of Letters Patent No. 778,109, dated December 20, 1904. Application filed March 19, 1903. Serial No. 148,578.

T aZZ whom, itmay concern:

Be it known that I, F ANK P. GALLAHAN, a

I citizen of the United States, residing at Graf,

in the county of Dubuque and State of Iowa, have invented certain new and useful Improvements in Corn-Planters; and, I do hereby declare the following to be afull, clear, and exact description of the invention, which will enable others skilled in the art-to which it'ap-v pertains to make and use the same.

My invention relates to corn-planters, and

i has for its object to provide positive means for automatically dropping corn at regular intervals and in parallel rows and at the same time to furnish visible marks to direct the driver both as to the rows and the place Where the corn has been dropped in the parallel rows.

I planting at regular. intervalsln A further object is to provide simple and effective means wherebyall ,theirregularities of the soil, together with the initial droppingat the beginning of the'rows, may be provided for under all circumstances'and the parallel rows easily and readily accomplished;

The details of construction whereby these and other objects are, successfully accomplished are'fully set out in the following specification when read in connection with the drawings accompanying the same.

Figure 1 is a perspective view of my improved corn-planter. Fig.--2.i's 'a perspective view of the main frame and theswinging supplemental frame with the latter shown slightly raised above the vmain frame. Fig.- 3 is a perspective of the axle and drive-wheel with means for throwing the Wheel into and out of engagement with the axle. Fig. 4 is a section through the axle, thimble, and drive' wheel with parts cut away. Fig. 5 is a perspective view of a collar attached to the axle with the means for attaching the lever that operates the drive-wheel. Fig. 6 is a perspective view of the under side of a portion of the stationary supplemental frame, show' denote corresponding parts in each of the figso that each wheel may turn independent of the other, and when the wheelsare reversed the axle will cease to rotate. Upon the axle 8 is rigidly secured a thimble 12, (shown in Fig. L) and upon and around this thimble and the axle is set a drive-wheel lei, adapted to be rotated by friction upon the thimble 12.

- J ournaledto the upper side bars of the frame is a shaft 15, upon which rotates a segmental gear-wheel 16. The periphery of this wheel is provided with a cog or toothed section 17 and the hub 18 of this wheel is provided with cogs 19, into which the gears 13 of the drive-Wheel 14 mesh and rotate the wheel 16. These cogs areof suificient length to permit the drive-wheel 14 to bemovedalong the axle when the wheel 1 1 is out of engagement with the thimble on the axle and still remain in I mesh with the cogs 1,9.v

The stationary supplemental frame 26, which is secured to the under side of the main frame 2, has bearings 27 at each end-thereof. In

these bearings is journaled a shaft 20, which extends to considerable distance upon both sides of the framefor' the purpose presently to be described and is rotated by the gearwheel 22, rigidly secured thereon. This wheel is rotated by its engagement with the wheel 16. The wheel 22 is provided with twice the number of cogs 18 that are upon the periphery of the segmental wheel 16, so that when the wheel 16 is rotated it will rotate the wheel 22 half-way around,and bymeans hereinafter described the cogs 17 on the wheel 16 will be brought into engagement with the same cogs 18 on the wheel 22 at each revolution, and

thereby control the dropping of the seed.

For the purpose of operating the seeding mechanlsm and also the marker, which indicates where the corn has been dropped in each hill, the outer ends of the shaft are provided with beveled gears 25. At right angles to and preferably beneath the main frame 2 is secured a stationary supplemental frame 26. This stationary supplemental frame consists of two parallel bars 28, curved at the center 29 over the wheel 22. The outer ends of the bars 28 are bent outwardly to form the bearings 30 for shafts 32. Upon each of the shafts 32 is set a beveled gear 33, adapted to mesh into the beveled gear 25. Outside of the bearings 30, at the forward end of the shaft 32, is attached a wheel 35. and near the circumference of the wheel, on the side, is a pin 36. To the pin 36 is pivoted a pitman 38, provided with a loop 39 at its outer end. In the seedboX may be a slide, (not shown,) which is provided with a bent arm 40, projecting out from the seedboX 42 and adapted to engage in the loop 39 of the pitman 38. It will be seen that at each revolution of the wheel the slide in the seedbox will be drawn out and forced in by the pitman 38, thereby dropping one hill of corn at each revolution of the wheel 35. On the opposite end of the shaft 32 is set a wheel 45, to which is attached a marker-arm '46. This marker-arm is formed in two parts 47 and 48. (See Fig. 7.) The part 47 is hinged to the part 48 a short distance below its upper end and is perforated near the top, through which a rod 49, attached to the part 48, projects. The rod 49 is provided with a stop 50 at its outer end, and between the stop 50 and the end of the part 47 is a coiled spring 51. The object of this construction is to provide means for the marker 46 to yield whenever it strikes any hard substance, and thus prevent it from being broken. The markerarm is adjustably attached to the wheel 45 by means of clip-bolts 44. This arm extends downward to a little below the base of the shoe presently to be described. As the wheel 45 is rotated the marker-arm 46 will turn with the wheel and at each revolution strikethe ground at right angles to the travel of the machine and mark the place Where the corn has been dropped.

For the purpose of arresting the rotation of the gears 25, and thus stay the seeding, the wheel 16 is perforated, and in the perforation is rigidly fastened a pin 52, which projects out at right angles a short distance on both sides of the wheel 16. To the underside of one of the bars 28 of the stationary supplemental frame 26 there are suspended lever-arms 53, one on each side of the wheel 22. At one end of this lever 53 is an arm 54, which projects upward and at right angles and is adapted to engage the pin 52. The other end of the lever 53 is bent at 55 and is provided with a lug 56, adapted to engage in a slot 57 in the hub of each of the gear-wheels 25 and lock the wheels 25 in their rotation.- When the wheel 16 is rotated and the first cog 17 next to the pin 52 commences to engage with the cog 18 on the wheel 22, the pin 52 will come in contact with the arms 51-, which will partially rotate the lever-arms 53 and will draw the lugs 56 out of engagement with the slots 57 on the hubs of the wheel and permit them to be rotated and also permit the wheel 22 to be rotated by thewheel 16. It will be seen that the cogs 17 on the wheel 16 will engage one-half of the cogs on the wheel 22 at each revolution of said wheel 16 and will always commence to come into mesh at exact opposite sides of the wheel 22.

The seeding mechanism is constructed entirely independent of the main frame of the machine and has no connection with the d raft, but is forced alongin front of the machincby the means hereinafter described. Zlt consists in the shoes or furrow-openers 60, one upon each side, upon which are set the seedboxes 42. The seedboxes are rigidly connected together by a bar 62. There are also braces 63 attached to the bar 62 and united to the forward end of the shoes; also, braces 64 run from the end of the shoes to the seedboxes 42. To the bar 62 is loosely attached two arms 68, which extend backward and are rigidly secured to the shaft 15. Upon the shaft 15 is attached an operatinglever7() for rotating the shaft 15 to raise the shoes and seeding mechanism.

Upon the shaft 15 and the stationary supplemental frame is set the usual sector-plate 65, and to the lever is attached a spring actuated dog or pawl 66, so that when the lever is thrown backward to raise the seeding mechanism the dog will engage with the sector-plate and hold the seeding mechanism at the height desired.

From the above construction it will be seen that the bar 62, shaft 15, and connectingarm 68 form a swinging supplemental frame which is always above the main frame and which when raised by the lever 70 swings with the shaft 15 as fulcrum.

It will be seen as the arms 68 are loosely attached to the bar 62 that when the lever 70 is drawn backward the shaft 15 will be rotated and by the arms 68 the seeding mechanism will be raised practically perpendicular and without in any manner tilting the main frame of themachine and entirely independent of the machine whenever it is necessary to pass an obstruction, turn a corner, or for whatever purpose. It will also be seen that the seeding mechanism is operated by itself and is independent in its movements of the main frame and that the wheel 22 is never disturbed and will always remain in mesh or in proper position for mesh with the wheel 16. It will further be observed that the draft is not attached to the seeding mechanism, but the whole seeding mechanism is forced forward from the shaft 15 by the engagement of the arms 68 with the bar 62.

For the purpose of marking the land, whereby the driver will be able to guide his team V 14 in and out of engagement with the thimble lugs 85 upon its opposite sides.

with one animal on each side of the marked line, there is attached to the rearend of the machine a marker 72 in the following manner: Betweenthe side bars of the main frame, near the rear, is placed a cross-bar 74, and upon this bar and the rear of the cross-bar or frame 4 is journaled the marker-shaft 75, which is bent at right angles, and to the outer. end is secured the marker 72. To the front end of the shaft 75 is secured a wheel 76, provided with two crescent-shaped slots 77. Against the. cross-bar 74 is pivoted a lever 78, provided with holes 79, one near the lower end below the frame and the other about the same distance above the frame. In these holes is loosely attached rods 80, which engage with the slots 77, one in eachslot. It will'be seen that by operating lever 78 the marker 72 may be rotated to mark from eitherside of the planter and will mark at midway between the rows contiguous to the rows planted.

For the purpose of movingthe drive-wheel 12 upon the axle 8 and for otherwise controlling the action of the drive-wheel the hub 82 of the wheel is grooved at 83, and within this groove is loosely fastened a band 84, carrying Around the axlel8 is also loosely fastened a collar 86. and provided with lugs 88 upon its opposite sides. The lugs 88 and 85 are connected together by bars 90, one on each side opposite. Between the'collar 86 and the hub 82' there is rigidly fastened 'upon the axle a collar 92, provided witha groove 93, and within this groove is loosely secured a ring 94, carrying lug 95 upon one side. To this lug 95 is pivotally secured a lever ,96, forked at its lower ends and extending downward upon opposite sides of the collar-92 and widened at 97, as shown in Fig. 3. For the purpose of rotating the wheel 14 without rotating the axle 8 there is attached to the hub 82 of the wheel 14 a ratchet 98, and upon the lever 96'is secured a pawl 99, adapted to engage with the teeth upon the ratchet 98, and when the lever 96 is drawn over toward the Wheel, drawing it out of engagement with the thimble 12,-the wheel 14 may be operated by thelever 96 operating the pawl 99 against the ratchet 98, and thus rotating the wheel 14.

The manner of operating my device is substantially as follows: The seed is placed in the seedboxes and the driver grasps the lever 96 and pushes it away from the wheel 14, which causes the part 97 to engage with the hub of i the wheel and forces the wheel onto the thimble-12. The team is then started, and the rotation of the axle 8 rotates the wheel'l4, which in turn rotates the wheel 16 by the engagement of the cogs 13 of the wheel 14 with the cogs 19 of the part 21 of the wheel 16. When the cogs 19 on the wheel 16 next to the pin 52 are about to engage with the cogs on the wheel 22, the pin 52 will come in contact with the arms 54 on the lever-arms 53 and will partly rotate the levers suflicientlyto draw the lugs 56out of engagement with the slots 57 in the hubs of the wheels 25 and permit them to be rotated at the same time the wheel 16 rotates the wheel 22. The rotation of the wheel 16 will also rotate the wheel 22 one-half way around, and as the wheel 22 is fixed upon the shaft the beveled gears 25 will be rotated, and at the same time the wheels will also be rotated and the slides drawn out tocause the seed to drop, and when the rotation of the wheel 35 is completed the slides will have been pushed back. At the same time that the seed is dropped the Wheels will be rotated and the marker 46 as the team advances will mark across at right angles to the place where the corn has been dropped in both rows. As the team advances the marker 72 will mark the line along the land parallel with the corn that has been planted and at the middle of the parallel rows to be planted on the return trip of the planter. WVhen the ends of the rows are reached, the driver throws the lever 96 in an opposite direction, which releases the engagement of the wheel 14 with the thimble 12 and stops the rotation of. the said wheel 14. He then'grasps the lever and draws. it backward, which raises the shoes and the seeding mechanism entirely off of the ground without any tilting or movement of the main frame and independent of the main frame. When the driver has made the turn and if he finds that the shoes and the dropping mechanism are not in proper position to drop the corn, he

advances the carrying wheels 10-until the dropping mechanism is in proper position. If the driver then finds that when the shoes are in proper position for dropping the wheel 22 is not in proper engagement with wheel 16, so that immediately upon thestarting of the team the dropping mechanism will commence operating, he grasps the lever 96 and rotatesthe wheel 14 by the engagement of the pawl 99 with the ratchet 98, which will rotate the wheel 14, and thus will rotate the wheel 16 until it will come in the proper place for engagement with wheel 22, then the driver by said lever 96 brings the wheel 14 into engagement with the thimble 12 and starts his team, and immediately upon the advance of the team-the dropping mechanism will commence to operate. The team is then driven with one animal oneach side of the line that the marker 72 has made when-the two former parallel rows were planted. The driver also at the time when the team is started turns the lever 78 in the opposite direction, which throws the marker 72 on the opposite side of the machine in a position to mark the ground for a guide to the driver on his return planting. It will be seen that if the ground is'un-.

even then the correction of the dropping mechanism may always be effected in the same manneras at the initial of the row. It will also be seen that as each carrying-wheel may turn independent of the other and independent of the axle in one direction if one wheel advances over an obstruction it will make no difference with the dropping mechanism, and if both wheels pass over some irregularities then the correction can be made as hereinbefore stated.

It will be observed that the driver has the entire machine under his control and the soil is marked to indicate not only where the seed has been dropped, but also a line which indicates the direction he is to drive his team and at all times can correct any irregularities in the dropping, whereby the corn can be planted practically in squares with almost as much accuracy as though the ground were absolutely level.

The various details of construction set out and described herein may be varied within wide limits and parts of the features may be adopted without adopting it as a whole and still be within the spirit and scope of my invention.
