Specification of Letters Patent.

Patented Sept. 27, 19M).

Application filed June 23, 1910. Serial No. 568,558.

To all whom it may concern:

Be it known that we, MATHEW MAUGER and CHARLES SormAw, citizens of the United States, residing, respectively, at Chillicothe and lieesburg, in the counties, respectively, of Ross and Highland and State of Ohio, have invented certain new and useful improvements in CornPlanters, of which the following is a specification.

This invention relates to certain novel and useful improvements in corn planters.

1n the present instance, in carrying out our invention, it is our purpose to provide a machine of the class described in which the devices for marking the location of the corn hills, for the planting of the corn, are so constructed and arranged that the location of each hill, will be accurate and positive.

A further object of our invention is to provide means whereby the marking mechanism will be actuated at predetermined times to perform the function of marking the hills, and furthermore whereby such marking mechanism may be thrown out of operation temporarily and then adjusted to make accurate markings in alinement with corresponding rows.

Heretofore in machines of this class with which we are acquainted, it has been difficult, when the machine has reached the end of one row and has been turned, to start the corresponding row, to mark with any exactitude the beginning of such succeeding row. With our improvements, however, we overcome this difliculty inasmuch as the machine itself may be brought to a standstill and the marking mechanism preliminarily actuated to mark the beginning of the next row.

A still further object of our invention is to construct a machine which will embody the features of durability and economy in the cost of production and operation.

lVith the above and other objects of a similar nature in view, our invention consists in the construction, combination and arrangement of parts set forth in and falling within scope of the appended claims.

in the accompanying drawings: Figure 1 is a. plan view of a corn planter embodying our invention, Fig. 2 is a view in side elevation of the same, Fig. 3 is a detail view showing the construction of the marking mechanism and its location relative to the corn dropping devices, Fig. 4; is a View in side elevation with the marking devices omitted and showing in detail the construction of the corn dropping mechanism.

Referring now to the accompanying drawings in detail, the letter A designates as an entirety the main frame of the machine, which may be of any ordinary construction, said frame in the present instance comprising the longitudinal or side bars 1 and the cross bars 2.

The numeral 3 indicates the axle of the machine, carrying the ground or traction wheels 4-4L These wheels are preferably loosely mounted upon the shaft, that is to say, with a pawl and gear structure so thatshould one wheel encounter any irregularity or obstruction on the ground, the opposite wheel will compensate for the same.

The seat standard is shown at 5, and is fastened to one of the cross bars 2, while the numeral 6 designates the seat of the machine.

At the forward end of the machine frame A, is pivoted as at 7 the supplemental frame 8 which carries the corn dropping mechanism. In this machine, there are two corn dropper-s designated as an entirety by the letter B, one at each side of the machine. We wish it to be understood that so far as the corn dropping mechanism proper is concerned, any suitable type of this device may be employed. in the present drawings, a description of one dropping device is also pertinent to its companion.

The numeral 9 designates the receptacle for the grains, which is mounted in the ordinary manner upon the front pivoted frame. The chute or tube 10 leading from the receptacle has in its lower end the opening 11 for the passage of the corn, said opening being controlled in the usual manner by the cutoff 12 carried by the arm 18 pivoted at 14, the upper end of said arm carrying the hook 15 adapted to be tripped at predetermined times by the oppositely disposed pins 1616 on the shaft 17.

The runners or furrow openers of the machine are shown at 1818 and 19 designates the gear wheel for operating the disk in the bottom of the corn receptacle 9. As these parts are of well known construction, no further description is necessary.

Mounted upon the shaft 1? are the sprocket gears 20, in driving engagement with similar sprocket gears 21 on the shaft 22, through the medium of the chains 23. Mounted approximately intermediate the shaft 17 is a sprocket 24: connected through the drive chain 25 with the sprocket clutch member 26, loosely mounted upon the shaft 27, the companion clutch member 28 being slidably mounted upon said shaft.

29 designates a lever through the medium of which the splined or sleeved clutch member 28 may be shifted into or out of engagement with the member 26.

The numeral 80 indicates a segmental rack to which is pivoted the lever 31 connected to the member 32 through a bell crank lever 38, the construction being such that the front or supplemental frame may be elevated and lowered in the ordinary manner to regulate the depth of the runners 18.

Mounted at each end of the shaft 22 is a marking device which forms an important feature of our invention, and as both of these devices are duplicates in construction, a description of one will be sufficient for both.

at indicates a block member at the end of the shaft 22, said member being slotted as at 3535 to receive the parallel ends 36 of the arms 37, these arms having their end portions preferably bent at an angle and each end carrying a marking shoe 38. The parallel ends 86 of the arms carried by the block members 3 1 are capable of limited lateral movement and are tensioned through the medium of the leaf springs 39, so that if in the revolution of the arm, the shoe should come into contact with a stone, clod or other obstruction, the arm may yield laterally to a certain extent and thereby obviate jars and shocks to the machine.

Carried by the shaft 27 is the ratchet gear 40 adapted to be operated by the lever 41 so that when the clutch member 28 is disconnected from the sprocket clutch member 26, the lever 41 may be operated, and through the medium of the chain 25, sprocket 24c and sprockets 20, 21 and chains 23, the shaft 22 carrying the markers may be turned so that the markers may be properly adjusted without moving the machine.

From the above description takenin connection with the accompanying drawings, the construction and operation of our improved planter, will be readily understood.

The operator seated in the seat 6 has under his direct control, the three levers 29, 31 and 41. Assuming the machine to be traveling along the field, regulating a row, the markers at each side of the machine are turning so that the shoes 38 strike the ground simultaneously as the pins 1616 on the shaft 17 trip the hook 15 at the upper end of the arm 13, thereby actuating the cut-off 12 to open the passage and permit the corn to drop. lVhen the end of the row has been reached, and the machine turned, if the marker should not be in a proper alinement to make the succeeding row, it is only necessary for the operator to throw the clutch member 28 out of engagement with the sprocket clutch 26 and actuate the ratchet lever 41 to move the shaft 22 and thereby bring one of the arms of the marker into contact with the ground at the predetermined point, so that the shoe will be in position to make the proper marking. The splined clutch member 28 may then again be thrown out of engagement with the sprocket clutch member 26 and the machine moved down the field, the marking taking place simultaneously with the dropping of the corn. As heretofore stated, in order to elevate or lower the front or supplemental frame and thereby adjust the depth of the runners, it is only necessary to actuate the lever 31 of the segmental rack 30, the frame being then adjusted through the medium of the bell crank 38 as heretofore described.

If desired, the passage leading from the receptacle for the seed, to the dropping chute or tube, may be controlled through the medium of a door or slide of any preferred character, so that should it be desired to shut ofi the flow or dropping of the seed for any reason, this may be accomplished by simply moving the door, thereby closing the passageway.

While we have herein shown and described one particular embodiment of our invention, we wish it to be understood that we do not limit ourselves to all the precise details of construction herein shown, as modification and variation may be made without departing from the spirit of the invention or exceeding the scope of the claims.

hat We claim, is

1. The combination with the main frame, the ground wheels therefor, an axle connecting said ground wheels, a supplemental frame, means for raising and lowering the supplemental frame, a corn dropping mechanism carried by said supplemental frame, a shaft carried by the main frame adjacent to the corn dropping mechanism, blocks at the end of said shaft, a plurality of angular laterally yielding shoe carrying arms carried by said blocks, means for driving the shaft from the axle, and clutch mechanism for throwing said shaft into and out of driving engagement with the axle.

2. The combination with the main frame, the ground wheels therefor having an axle connecting the same, a supplemental frame pivoted to the front of the main frame, corn planting mechanism carried by said supplemental frame, spring tensioned shoe carrying marking arms arranged adjacent to said planting mechanism, means for permitting said arms to oscillate laterally, driving mechanism whereby the planting mechanism and the marking devices are operated in unison, and a lever for adjusting the marking devices relative to the ground independently of the actuation of the planting mechanism.

3. The combination With the main frame, the ground Wheels therefor, an axle connecting said Wheels, a supplemental frame carried by the main frame, corn dropping mechanism carried by said supplemental frame, a shaft arranged adjacent to the dropping mechanism, slotted blocks at the ends of said shaft, marking devices comprising a plurality of angular shoe carrying arms carried by said blocks and capable of lateral movement relative thereto, means for operating the marking mechanism simultaneous With the operation of the dropping mechanism, and means for operating said marking mechanism independently of the operation of the planting mechanism.

In testimony whereof We aiiix our signatures in presence of two Witnesses.
