' SPECIFICATION forming part of Letters Patent No. 539,267, dated May 14, 1895.

Application filed-Tun 26.1894. Serialllo. 515,783; (Nomocleh) To all whom it may concern.-

Be it known that we, ALBERT J. H LVERN and JOSEPH W. MCGUIRE, of Burrows, in the county of Carroll and State of Indiana, have.

invented a new and useful Improvement in' chine that it will be exceedingly simple, du-.

rable and economic, and whereby the various .parts will be automatically operated, being driven from one of the ground wheels of the machine.

Another object of the invention is to provide check markers which will drop in order to make a mark, and will move rearward while the mark is being made, thesaid check mark-;

ers having a timed return movement.

Another object of the invention is to provide a trip device adapted to control the mech-. anism operating the drop slide, and operated by a wheel independent of the frame of themachine and located ina manner to track one: of the ground wheels or supporting wheels of the machine, and'to provide this following wheel with a mechanism through the mediumc of which it may be'm'ade to gain or to lose inrevolution when required, to insure accuracy in planting.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth,

and pointed out in the claims.

Reference is to be had to the accompanying drawings, forminga part of this specification, in which similar figures and letters of refer o erence indicate corresponding parts in all the views. 4

Figure 1 is a plan view of the machine. Fig. 2 is a vertical longitudinal section taken substantially on the line 2 2 of Fig. 1. Fig.

3 is a front elevation of the machine, the pole being in section. Fi-g.- 4 is a partial front ele: vation and partial sectional view of the regulating-wheel, its standard or support being in cross-section. Fig.5 is a plan view of one of the marker-arms, and Fig. 6 is a detail view illustrating the driving-wheel and its relation to the ground-wheel from which it is to receive motion.

The frame of the machine may be said to consist of two. sections A and B. The section A usually comprises two side bars 10 connected by a rear bar 11, and this frame is secured upon an axle 29, the said axle being provided with ground Wheels 30, loosely mounted thereon. The frame B, which is the-forward section, '66 usually consists of front and rear bars or beams 13 and 14, and intermediate longitudinal beams or sills 15, and the pole is secured to this portion of the frame. The runners 16, are secured to the forwardframe section B,

.and above the runners the seed boxes 17, are a placed, being provided with a reciprocating seed drop slide 18.

The forward frame section B is pivotally connected through the medium of links 19 '0 with the forward portion ofthe rear section of theframe, preferably immediately under the front bar 12 located upon the rear section Aand extending transversely across the same and beyond the sides of the frame, as shown in Fig. 1. The section B of the frame is lower than therear section A, and the inner ends of the sills 15 ofthe front section B, are connected by links 20, with crank arms 21, projected forwardly from a rock shaft 22 mounted 8g upon the frame section A, preferably forward of the axle. Thisrock shaft is provided with a hand lever 23, having the usual thumb latch for engagement with a rack 24. A standard 25, is usually secured to the axle and curved 8 upwardly and rearwardly to support the drivers seat 26, and pedals 27 and 28, are projected forwardly and rearwardly from the rock shaft 22, whereby when the driver places his weight upon the pedals the rock shaft will go i be manipulated in a manner to either raise or lower the forward frame section, the hand lever 23 being in the meantime disconnected from the rack. In this .manner the weight of the driver is utilized to adjust the frame.

The driving wheel 31 of the operative mechanism of the machine is adapted for frictional engagement with one of the ground wheels 30, and the said wheel is illustrated in Fig. 6, and is shown as provided with two opposite flat 10 peripheral surfaces 31, and it is also provided with pine 3l ?,projected from one face at each side of the center. The fiat sides are provided upon this wheel in order to allow free passage between the hills of corn. The driving wheel 31, is mounted upon ashaft 32 provided at its forward end with a crank arm 33, the shaft being mounted in abracket 34,supported upon the cross bar 12 of the main section of the frame.

A red 35, is pivoted upon the crank arm 33 of the driving shaft 32, and this rodis held to slide in an arm of the bracket 34,being given an upward and outward inclination. The rod 35, is surrounded by two springs 36 and 37, the spring 36' having bearing upon. the bracket and the head of the rod, and the spring 37 has bearing upon a collar located on the rod near its connection with the crank arm and against the under face of the bracket, whereby in a complete revolution of the crank arm 33 both of the springs 36 and 37 will have been 001111 pressed or placed under. tension and again permitted to expand.

The seed drop slide 18 is driven by a link 38, pivotally connected with the said crank arm 33 and with a bracket arm 39, located upon the seed drop slide, the said link 38' being provided with stops 39 at each side of the bracket 39, whereby the said link will have.

a certain amount of play so as not to retard the movement of the driving friction wheel. A second link 40, is also pivoted upon the.

31. said crank arm 33 of the drive shaft, and the link 40 is carried through an opening made in the angular shank 41 of'a latch 45, and this link 40, is provided with stops 42 at each side of the latch shank, and springs 43 and 41 engage with opposite sides of the shank and with the said stops, whereby when the link is moved in one direction one of the springs will be compressed and the other free to eX- pand, and vice versa.

The latch 45 is bifurcated or forked, and receives between its members a finger 46, which is projected downward from a crank shaft 47, held to rock in suitable standards or boxes located upon the front crossbar 12 of the main section of the frame. This crank shaft is provided with a crank arm 48 near one of its ends, and with a crank arm 49 at each of its extremities.

The markers C are located one at each side of the forward portion of the main or rear section of the frame, and stirrups 12* are preferably attached to the under face of the cross bar 12, as shown in Fig. 3, and in each of these stirrups a shaft 51, is mounted to turn, provided with a crank arm. 51 at its lower end, and upon this crank arm the body section or beam50 of the marker is pivoted, the beam beingcapable of vertical movement upon the crank arm,and of a swinging movement in direction of the front or rear, by ieason of the shaft supporting it turning in its bearings.

A plan view of the body section of a marker is shown in Fig. 5. The marking plate 52, is attached at the outer end of the beam 50,and

is secured to said beam through the mediuni of a metal pivot 11 and a wooden pin, a, in order that should the marker meet with an obstruction which would strain the marking plate, or strain the mechanism of the machine, the wooden pin a will break, and the marking plate or blade will turn upon its remaining fastening device and clear the obstruc' tion.

Each of the shafts 51 is provided at its upper end with a crank arm 54, which will extend outward in direction of the sides of the machine when the lower crank arms 51 extend in a forwardly direction, as illustrated in Fig. 3. A red 53, is pivoted at its lower end in each of the marker beams 50, and the said rods are carried upward through a suitable opening made in the crank arms 54 of the shafts 51, and a spring 55, is coiled around each of these rods, having bearing against the beam and against the upper crank arm 54, the said springs acting to normally force the beams 50 downward to a horizontal position, and the marking plates or blades 52 into the ground.

Each of the marking beams 50 is connected by a chain 56 with an end crank arm 49 on the crank shaft 47, and when this shaftis re volved in a manner to elevatethe said crank arms 49, the marker beams will be raised and the blades carried out of engagement with the ground,as shown in Fig. 3,the springs being then placed under tension. In the operation of these markers, as soon as the seed is dropped the markers will be dropped into the ground by the springs 55, and the machine in going forward will cause the markers to travel rearbeen raised, whereupon they will automatically swing to their forward position at right angles to the sides of the machine, and upon reaching that position the crank shaft will have been actuated in a manner to permitthe springs 55 to draw down their crank arms 49,

and permit the marking blades to enter the ground.

As heretofore stated, the springs 55 conneeted with the marker beams, serve to throw said beams downward, but the shaft 47 is rocked in a direction to draw the beamsupward through the medium of an arm 57, which is pivoted upon the crank arm 48 of said shaft. This arm is adapted to rest upon the axle of the ground wheel 30 at its free end, and is provided with a slide '59, which may be adjustable and spring-controlled, the said slidebeing adapted for contact with pins 58, located upon the hubof the left-hand ground wheel 30, and the operation of rocking the shaft 47 is accomplished by the pins 58 engaging with the slide 59 and pushing the crank arm 48 upward. t

A beam 60, preferably tubular, has sliding and pivotal connection with the right-hand side of the front bar of the main section of the frame, whereby thersaid beam may 7 have lateral movement and likewise a vertical movement. This beam is rearwardly arched, and is carried beyond the rear of the frame section A. At the lower rear end of this beam a regulating wheel 61 is located, adapted to travel upon the ground and track either of the ground wheels, preferably the right-hand ground wheel 30. The axle 62 upon which this wheel revolves, iscarried through the beam 60, and is provided at one end with a crank arm 64. The hub of the wheel 61 at its right-hand side is provided with offsets 64, preferably two in number and equally spaced, as shown in Fig. 2.

An angle arm 65, is fulcrumed upon the wheel 61, just within its rim, and preferably upon its left-hand side. Two ofjthese arms are employed, and they are placed diametrically opposite, and one of the members of each arm, the outer one, is sharpened or pointed, and is provided with a regulating blade 66, extending at right angles'from said member. Each of the arms 65, is connected with the left-hand crank 63 through the ruedium of a link 67, and the right-hand crank 64, is connected with a link 68, which is car-V ried to a connection with a hand lever 69, fulcrumed upon the beam 60, and provided with a hand latch for engagement with a rack 70.

The regulating arms 65,are adapted to be brought into operation in the event the machine should lose or gain in the matter of planting. In the event it should lose, the lever 69 is carried forward, for example, to the forward notch of its rack, 70 and the crank arm 63 operated from that lever will sooperate upon the regulating arms 65 as to cause the pointed members thereof to extend well beyond the periphery of the wheel, and whenever one of these arms is brought down to an engagement with the ground, the pointed member, in entering the ground, will bring v the blade 66 connected with it upon the surface, and at that time the wheel 61 will not engage with the ground, as shown in Fig. 2.

It is intended that in a complete revolution of the wheel 61, two hills shall have been planted. When the lever 69, is carried to about a central position upon the rack, the regulating arms 65 will be brought within the rim of-the Wheel, and the wheel will travel as though the regulating arms were not applied to it. In the eventthemachine should gain in planting, the gain will be compensated for by carrying the lever 69 well'to the 'rear, thus changing the position of the regulating arms 65 with relation to the periphery of the regulating wheel.

An angle or elbow level-71, is fulcrumed in the beam '60 supporting the regulating wheel,

wheel-isrelieved from engagement with the latch only twice in a complete revolution of the regulating wheel 61, and this is accomplished-by ahead 77, formed upon the angled When the pins are engaged by lever 71, located adjacent to said wheel, and

when thevprojections 64 on the hub of the wheel engage with said head.

In the operation of the machine, when the regulating wheel acts to remove the latch 76 from engagement with the teeth 31 of the driving wheel 31, the spring 36, or 37, of the rod 35, whichever of the springs is compressed, will at that time turn the wheel 31 a sufficient distance to bring the rounded'section of its periphery in engagement with the V supporting wheel 30. The shaft 32 will then be revolved during the contact between its cylindrical surface and the supporting wheel, the drop slide will be moved to drop seed, the

disengaging of the finger 46 from the latch 45, and the springs 55 of the markers will act to cause the marking blades to mark the hill, the latch 45 being moved in a direction to hold the rock shaft 47 stationary by engaging with its finger or arm 46. The markers will now be drawn rearward, and at that time the slide59 will have been acted upon by the pins 58 to carry the rock shaft 47 in a position to elevate" its crank arms 49 and thus elevate the marking beams, whereupon the beams will swing around to the front, being so drawn by the chains supporting them, together with the springs 55; and as soon as the cylindrical section of the friction driving wheels ceases to contact with the ground wheel, one of the pins 31 will be engaged by the latch 76, since the latch will have been dropped in position to engage with these pins the moment that the angle lever 71 clears a projection 64 on the-hub of the regulating wheel.
