SEED-PLANTER.

SPECIFICATION forming part of Letters Patent N 0. 402,669, dated May '7, 1889.

Application filed September 29, 1888. Serial No. 286,718. (No model.)

To all whom, it may concern.-

r Be it known that I, GEORGE D. HAWORTH, of the city of Decatur, county of Macon, and State of Illinois, have invented certain new and useful Improvements in Seed-Planters, of which the following is a specification.

My invention relates, first, to mechanism for drilling the seed; second, to a device for regulating the depth of the out of the runners; third, to a lock to hold the runners in the ground, and, fourth, to a detachable device for marking the ground to guide the driver.

In the drawings accompanying and forming a part of this specification, Figure 1 is a side elevation of a corn-planter embodying my invention. Fig. 2 is a plan of the drill mechanism. Fig. 3 is a front elevation of the same. Fig. 4 is avertical section of the rotating head of the drill mechanism. Fig. 5 is a plan of a side of a planter with a marker attached thereto. Fig. 6 is a perspective view of the device used to regulate the depth of the cut of the runners. Figs. 7 and 8 show details in the connection of the marker-bar. Fig. 9 is a perspective view of the principal element in the device for regulating the depth of cut of the runners. Fig. 10 is a face view of the head shown in Fig. 4, taken from the right side of said figure; and Fig. 11 is an elevation of the same device, taken from the opposite side.

A sprocket-wheel (indicated by referenceletter a in Fig. 1) is secured to a planterwheel in a position concentric therewith. A sprocket chain, Z), connects Wheel a with sprocket-pinion c of the drill mechanism and conveys motion from the planter-Wheel thereto. Arm d pivots loosely in line with the axle of the planter and carries roller 6, that bears 011 chain b in a manner to take up slack. The shaft 9 (seen in Figs. 2 and carries pinion c and rotates therewith. The head 7.; Z ordinarily rotates with shaft g, on which, however, it is loosely mounted, as will here inafter appear, and it has a bearing, a, for the L-lever, that conveys motion to the seedslide of the planter. The L-lever comprises the arm 19, that pivots 011 vertical stud q and has a termination, s, to actuate the seed-slide, and arm 0, that is actuated by the head and has forks 0 0, that pivot on arm 19. The seed-slide a has a slotted bracket, 2, in which the termination of arm 1) operates. The arm 19 has an end projection at r to form a hearing for fork 0' and has a pivot at r in line with 1, that forms a bearing for fork o". The stud q is supported by bracket x. The shaft 9 has hearings in bracket w. Both brackets are secured to a cross-bar, r, of the planterframe. The rotation of head is Z is imparted to the end of arm 0, the forks rock on arm 13 and impart oscillating motion thereto, the end 8, working loosely in the slot of bracket 15, imparts rectilinear reciprocating motion to the seed-slide u, and the seed is dropped at short and regular intervals. This is the operation in detail. Briefly expressed, the L- lever acts as a pitman in conveying the rotary motion of the head to the reciprocating seed-slide.

The head is composed of tWo plat-es, k and Z. The first,'as may be seen in Fig. 4, is slotted at and has a hole for bolt on. It also has a collar, 70, and a boss, is, with grooves in its face. The second plate Z,is slotted narrowly at Z to receive bolt m and more widely at Z" to receive boss 70'. It projects laterally at 01. into slot k, and its projection has perforation n to receive the end of arm 0. This construction, with the exception of the collar and boss on the inner plate, is to permit the length of the stroke of the seed-slide to be regulated, the requisite operation consisting simply in loosening bolt m, moving projection a nearer to or farther from the shaft, and retightening the bolt.

A slide, h, engages the collar of plate It. It haslongitudinal motion on the shaft, and it is provided with ledges v1 and tooth 2". (Seen in Fig. 3.) A lever, f, f ulcrumed over the slide, has projections f and f extended beyond the' fulcrum in nearly-opposite directions. WVhen the lever is thrown in one direction, a projection striking against the tooth carries the slide, and With it the head, along the shaft. lVhen thelever is thrown in the opposite direction, the opposite projection strikes the tooth and returns the sleeve and head to their original positions. tion, which may be easily driver With his foot, enables This operaeffected by the the slots of the boss to be made to engage or disengage pins g of the shaft, and so cause the head to operate or not, as may be desired.

In Fig. 5, 15 is the marker, 16 the markerbar, 17 a line connecting the marker with the eye of hook 1S, and 19 is a line extending from the bow of the hook to the driver on his seat. The washer 20 is secured to the end of the planter-axle and has the elongated knob 21, as shown in Fig. 8. The bar 16 has a casting, 22, that is slotted in the direction of the length of the bar at 23. A whittletree is shown at Bet and a planter-wheel at 25. The marker-l'mr is attached by placing the casting in line with the knob, slipping it over the same, swinging the bar to the position shown, and catching the hook in the whittletree-ring or other convenient point of connection.

hen the end of the field is nearly approached, the driver pulls line 19, detaching the hook from the ring, and draws the marker forward until the bar is in line with the direction of the motion of the planter, when the slot will slip over the knob, and the bar will thus be detached from the planter. After the team has been turned around the marker may be replaced on the opposite side of the planter in the manner heretofore specified.

In Fig. 6,10 represents a slotted bracket permanently secured to the axle of the planter. 11. represents a slotted bracket permanently secured to the frame carrying the dropping mechanism, and 26 represents a bolt connecting the brackets in a manner permitting free vertical motion. Secured to the axle in a manner permitting vertical adjustment is bracket 12. (Seen clearly in Fig. 9.) This bracket has projection 13, that extends between the permanent brackets under the bolt and limits the downward motion of the planting mechanism and the depth of the out of the runners.

The extent of the slots in the permanent brackets limits the extreme adjustment of the planting mechanism. The adjustable bracket is used to limit the depth of penetration of the runners to suit various conditions of soil, season, 850., it being desirable to plant deeper at times and under some conditions and shallower at other times and under other conditions. The adjustable bracket has a longitudinal slot, 1i, through which the securing bolt passes; but other well-known means may be employed to give the necessary adjust ment.

In Fig. 1 reference-mimeral 1 designates the hand-lever used to raise and lower the planting mechanism. 2 is the seat-supporting bar, provided with staple 3. t is a lock bar swinging pendent from a pivot on lever 1. and having teeth 5 and 6, adapted to staple P. The rod 7 is used to connect lever 1 with treadles. (Not seen.) Rod 8 connects lever 0 is the 1 with the flanting mechanism.

standard on which lever 1. pivots. The lock bar is curved or forwardly inclined, and is swung in such position that the lever may be raised and lowered without the teeth engaging the staple. This enables the driver to regulate the depth of cut of the runners above a certain limit by pressure of his feet on the treadle. V11 e11 it is desirable to cut at a uniform depth, the lock-bar is swung back of the staple and a tooth is caught therein.
