CORN-PLANTER.

SPECIFICATION forming part of Letters Patent No. 574,539. dated January 5, 1897'.

Application iiled August 3, 1895.

1'0 u/ZZ 'u1/1.0717, t 11M/.n concern' Be it known that I, EDWARD M. HEYLMAN, of Canton, in the county of Fulton and State of Illinois, have invented certain new and useful Improvements in Corn -Planters, of

which the following is a specification.

rlhis invention relates to various details of a complete planter, all of which are capable of conjoint use. It is exemplified in the strucro ture hereinafter described, and it is defined in the appended claims.

In the drawings forming part of this specification, Figure 1 is a plan of so much of a planter as is requisite to show the corelation 15 of the different features of the invention. Fig.

2 is an elevation of the wire-reeling mechanis1n,viewed from the right side of the planter. Fig. 3 is an enlarged detailrepresentation of the friction-developing device of the reel. Fig. 4 is a rear elevation of the reeling mechanism. Fig. 5 isan elevation of the left side of the reeling mechanism. Fig. (i is an enlarged detail of the lock-bracket of the reel. Fig. 7 is an elevation of a seedbox and shank with the check-row head removed and the check-row lever cut on sectional line Xin Fig. 1. Fig. S is a detail of the check-row movement. Fig. 9 is arepresentation of the ratchetwheel of the check-row movement. Fig. 10 illustrates the mechanism employed to actuate the second drop of the planter and shows in connection therewith a peculiar intermediate drop. Fig. 11 shows the same features as Fig. 10, but represents the second dropvalve open and the intermediate valve closed instead of the reverse. Fig. 12 illustrates the manner in which the intermediate valve may be used to hold the second drop-valve open when the planter is used for drilling, and Fig. 4o 13 shows the intermediate valve in perspective and applied to such use. Fig. 14 is an elevation of the combined hand-and-foot drop, the elevation being taken on line Y in Fig. 1. Fig. 15 illustrates the reverse position of the mechanism shown in Fig. 14. Fig. 16 is a side viewof the rear end of the tongue.

So far as this particular invention is concerned the general construction of the planter may be varied to a considerable extent apart from the particular features claimed; but it serai no. mm. oto model.)

is preferably made substantially as shown in Fig. 1, where the axle is represented by 1; a wheel by 2; a side and end frame, formed of a continuous bar, by 3 and 3"; a cross-bar,

to which the side bars are hinged and which 55 carries the seed boxes, at t; an in terinittentlyrotating drop-shaft at 5 5 seedboxes at 6 a tongue at 7; a lift-bar at il; and other features, as indicated.

The lower surface of the rear end of the 6o tongue is rounded off, as shown at 'L in Fig. 16, and a plate, as 13, with a reversely-rounded end 13, is fastened to the under side of the tongue. Between the tongue and the plate is placed a spring-bar S, the rear end of which extends beyond the end of the tongue and provides a point'of connectionfor the links 10, (in Fig. 1,) which connect the spring-bar with lift-bar Sl. The plate is preferably cast with lugs 14, extended beyond the sides 7o of the tongue, a saddle 12 is placed on the upper surface of the tongue, a U-bolt is placed in the saddle, wit-h its ends extended through the lugs of the plate, as shown at 11, and bolt 13b is passed through the plate and through 75 a hole in the tongue. This mode of construction provides a stiff strong plate, which may be att-ached to the tongue without weakening either plate or tongue; butin the broadest sense of this feature of the invention it is only 8o necessary that the spring-bar shall be held between the tongue and the plate and that the rounded surfaces shall be provided. The spring-bar S supplies sufficient elasticity to make the connection between the wheel-frame 8 5 and the box-frame desirably yielding, and the rounded bearings strengthen the spring against sudden shocks or unusual stress.

The vertical support for the seat is in the form of an arch 2S, which rises from side bars 9o 3. Brackets 29 and 33 are secured one tothe left leg and the other to the right leg of the arch-frame, and both'are concaved in their upper surfaces to receive the journals of the shaft 31 of the reel-drum 32. Bracket 29 has 95 a transverse recess to admit a lock-pin, as shown in Fig. (i, Where the recess is indicated by 30 and the lock-pin by 52. rlhe pin when used extends through the recess of the bracket and through a coinciding hole in the reel- Ico shaft. Its function is to prevent the shaft from turning in its bca-rings, and its utility will hereinafter appear.

The reel consists of the drum 32, held between the flanged spider-heads 32 by bolts 32, and the bearings of the heads are loose on the shaft. A friction-wheel 3S (in Fig. 3) is fixed ou the reel-shaft adjacent to one ofthe reel-heads, and the periphery of the wheel is preferably V-shaped in cross-Section. A bracket 3G is fastened to the reel-head adjacent to the friction-wheel and is provided with bearing-pins 37. A pair of semicircular clamps embrace the friction-wheel, such clamps being designated by 35. At one end of each of the clamp members is a hook 35, adapted to engage a bearing-pin of bracket 3G, and at the opposite end is an extension 35", through which bolt extends. The bolt is somewhat elongated. It is screw-threaded to receive nut 4U, and spring 4l is interposed between the nut and an extension of a clamp member. A sprocket-pinion 27 is fixed on the reel-shaft, and a chain 26 connects the piuicn with a sprocket-wheel 25 on axle l. On the scraper-shaft 523 is loosely mounted a wireguide 4S, which has at its front end a wirereceiving eye 49. Back of the eye (when the guideisin a wire-receiving position) the guide extends in a regular curve backward and upward, and its under surface is concaved in cross-section to hold the wire against lateral displacement. The bearing of the guide on the scraper-shaft is elongated, as shown at45 in Fig. 4, thereby facilitating sliding motion of the guide lengthwise of the shaft, a lug 44 is formed on the side of the guide, a link 43 connects the lug with the lower end of lever 42, and the lever is pivoted on a pin 34, which projects from reel-bracket 33. Fingers 46 extend rearward from the bearing of the guide in position to strike the under surface of the rear cross-bar 3 of the planter-frame, and their function is to eoact with the wire in holding the guide in the position shown in Figs. 2 and 4. Stop extensions 47 project from the guide-bearing lengthwise of the scraperbar, and by striking against the journalbraekets of the shaft prevent the guide from traveling past the ends of the reel.

In Figs. 2 land 4 the reel is represented in the act of taking up the wire automatically as the planter travels across the field, and preliminary to such operation the following acts have been performed: First, the wire, which is designated by 50, is threaded through the guide and attached to the reel; second, the wire is caught over the guide-hook 5l, attached to the forward part of the planterframe; third, the nut 40 is adj usted until the spring 4l exerts the proper pressure on the clamps to produce friction sufficient to wind the wire fast as it is supplied and provide for slippage when the travel of the plan teris slower than thewinding speed of the reel, and, fourth, the pin 52, if in the locking position, (shown in Fig. 6,) must be withdrawn. Then as the planter moves forward the rcel-shaft is driven positively by the chain and the fixed wheels and the rcel turns in the saine direction with a force dependent on the amount of friction developed by the clamps on the friction-wheel. The natural speed of the reel, slippage not being considered, is more than sufficient to take up the wire as fast as the planter travels, and so the wire is wenn d with a degree of tightness depending` on the adjustment of nut 40. As the planter moves forward the driver grasps lever 42 in his right hand and with a slow steady motion back and forth moves the guide from side to side and evenly distributes the wire on the reel.

In Fig. 5 the reel is represented in the act of laying out the wire, and preparatory to this operation the lock-pin has been placed in position to hold the reel-shaft from rotation and the tension of the friction device has possibly been loosened. The effect of the friction in this case is simply to impede the rotation of the reel on the shaft sufficiently to properly stretch the wire as it is laid out. In this iigure the wire-guide, which is inoperative and therefore hanging loose from the scrapershaft, is shown enconnteriugan obstruction and swinging backward to pass over the same. This is a possibility incidental to the loose mounting of the guide on the round bar or shaft, and the utility thereof is obvious.

The utility of the fingers 4G of the guide depends on the relation of the scraper-shaft to the rear cross-bar of the frame, the shaft occupying a position below and somewhat in front of the bar.

The check-row head 54 is in this instance provided with a horizontally-swinging forked lever 55. The lever is connected with rod 5G through the intervention of a eoncaved saddle-block 57 and a hook-bolt or eyebolt 58. The block sits on the rod, with the end of the lever on the block. The bolt embraces the rod and passes through the block and lever, and when it is tightened it tends to bend the rod to an extent sufficient to make the connection secnre and provide for very nice adjustrnent lengthwise of the rod.

The rod 5G connects the forked lever with arm 59, which is pivoted at its opposite end with some relatively-fixed part of the planter, in this inst ance a bracket depending from the seedbox 6. A drive-pawl (30 is pivoted on the arm between the ends thereof and its free end forked to an extent sufficient to engage the round bars 02 of ratchet-wheel (5l both top and bottom. The ratchet-wheel is fixed on the drop-actuating shaft 5, and it comprises the disk-wheel 6l, the round bars G2, projecting from the face of the disk, and the ring 6I on the extended ends of the bars. The pawl engages a bar of the wheel with its ex tension GO (in Fig. 8) under a portion of the same, and when a throw is made, as shown in Fig. 7, a positive stop is eifected by the bar next following striking the under surface of the pawl. On account of the peculiar relation of the IOO IIO

pawl to the bar the front end of the pawl is held from rising as the throw is completed and its under surface lies in the path of the bar next following. The pawl acts between the disk and the ring of the ratchet-wheel, which provide ample space, and on this account the pawl may be joined loosely to the arm and still keep accurately to its work.

A lift-ratchet wheel 7 6 is fixed on shaft 5 under the seedboX, and it tends to actuate a lever 63 of somewhat peculiar construction. The lever has an incline or tooth 64:, adapted to the recesses of the lift-ratchet. It is pivoted at 65, it is annular at 66 to permit passage of corn, and it has at its free end eye 67 and hook 68. A rod 69 connects the lever with the second drop-valve 70, and as the liftratchet is turn ed the lever rises to open the second drop-valve and falls to close it. The plate under the rst drop-disk of the planter has a diminutive spout 71, and a valve 72 is swung from lugs 73 in position to close the spout. The free end of the intermediate valve 72 rests on the swinging end of lever 63, and when the lever rises to open the second drop-valve it carries the intermediate valve against the spout and precludes the passage of corn until by a reverse motion the second drop-valve is closed. This prevents dribbling,

-which may otherwise occur when a planter is moved unusually slow.

To adj ust the intermediate valve accurately and to provide for compensation for wear, a set-bolt 74, adapted to bear against the lever and provided with a jamb-nut, may extend through the valve, as shown.

When it is desired to use the planter for drilling, the second drop-valve may be held open by hooking end 68 of the lever 63 through slot 7 2, Fig. 13, of valve 72, as shown in Figs. 12 and 13. To facilitate this use of the intermediate valve, the pin 7 5, which holds the valve in connection with lugs 7 3, is made easily removable, and the slot is of course so located that the lever will be raised when the hook is therein.

A hand-lever that may be used independent of the check-row-wire mechanism by a boy seated on the planter is generally considered to be a necessary adjunct of a complete planter, and in some instances it is advantageous for the driver to actuate the drop with his foot. To provide a single device that will meet both of these requirements is the object of the mechanism specifically illustrated in Figs. 14 and 15, and the details thereof are as follows: Ratchet-wheel 2O is the same as the wheel (il of Fig. 9. Bracket 17 is journaled on casting 16, Fig. 1. Hand-lever 1S is fastened to bracket 17, on one side thereof. Pawl19 is swung from the opposite side of the bracket, asis also connecting-bar21. Casting 22 is secured to the planter-frame, and it provides a pivotal support for the foot-lever 23 and a housing for spring 24. The spring tends to hold the different parts in the positions shown in Fi 14, and it retracts the pawl after it is thrown to the position shown in Fig. 15, whether the operation be effected through the foot-lever or the hand-lever. The pawl is V hooked to correspond with the forked peculiarit-y ascribed to pawl 60. It bears against the ratchet-bars top and bottom, and it has an under surface at 19b which acts as a stop at the completion of athrow by impeding the motion of the bar following the one with which the hook is engaged. The hooked part 19 (seen only in Fig. 14) bears against the under surface of the bar and prevents the pawl from rising as the stop is made.

The housing 22 is cut away at its under side to receive the spring and permit motion of the foot-lever, and its extreme forward end forms a recess that retains the spring in position.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1.
