SPECIFICATION forming part of Letters Patent No. 358,537. dated March 1I 1887.

Application filed July 10, 1886. Serial No. 207,690. (No model.)

To @ZZ whom, t may concern:

Be it known that l, SILAs S. BRoons, a citizen of the United States, residing at Windsor, in the county of Henry and State of Missouri, have invented certain new and useful Improvements in Corn-Planters; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

My invention relates to planters; and it cousists in the novel features more fully hereinafter set forth, claimed, and shown in the accompanying drawings, in which- Figure l is a plan View of a planter of my construction embodying my improvements. Fig. 21's a section on the line X X ofFig.1, parts being broken away. Fig. 3 is a front view with parts broken away. Fig. 4 is a section on the line Y Y of Fig. 2 on an enlarged scale, parts being broken away. Fig. 5 is an end and reverse plan view of the front portion of the vibrating lever for actuating the graindisk-operating mechanism. Fig. 6 is a perspective view of the tappets for vibrating the operating-lever. Fig. 7 is a rear end View of the vibrating lever. Fig. 8 is a section on the line Z Z of Fig. 2, parts being broken away. Fig. 9 is an enlarged side view of the clutchshiftin g lever.

The frame A is supported on runners B and wheels C. The latter are mounted loosely on the ends of the axle D, and are ratcheted on the inner face of their hubs to engage clutchsleeves E, keyed ou the axle to revolve there- With, but free to have a longitudinal movement to and from the wheels. Levers F, having bifurcated ends f, are connected at their opposite ends to the frame in such manner that the ends of the bifurcations fit into grooves e in the clutch-sleeves, and pitmen E connect the clutch-operating levers with a hand-lever, F', pivoted to a seat-supporting bar, G. The hand-lever is pivoted vertically to vibrate laterally and in the direction of the shaft of the machine to and from aratchet-segment, g, and has the pitmen connected therewith on opposite sides of and equidistant from the pivotal point. The hopper H has two discharge-openings through its bottom, which communicate with the tubular braces b by means of spouts h.

Short shafts I, journaled vertically in the frame-and hopper, extend through the bottom of the latter, and are provided with disks J, having a series of openings,j, arranged around in a circle to register with the discharge-openings in the bottom of the hopper. The disks are keyed to the shafts and approach close to the bottom of the hopper, so as to prevent any seed getting between them and the bottom. Pinions yJ, keyed to the lower ends of the shafts, are alternately acted on by two teeth, k, extending from opposite ends of a crosshead, K, secured midway its ends to the end of the lever L. The pinions intermesh, and each being alternately actuatedthe motion of one is imparted to the other, so that both receive a continuous rotary motion.

The teeth k are beveled on the inner sides in an outward direction. By this construction the outer ends or sides of the teeth engage with the teeth of the pinion during the movement of the head,while the inner sides ride the teeth. Thus while one is engaging with and moving one pinion the other is riding the teeth of the otherpinion, and vice versa. The crosshead is made sufficiently elastic to yield when its 'tooth is riding the teeth of the pinion, and during the reverse movement bring said tooth in engagement with the teeth of the pinion. A slight torsional strain on the operating-lever L can be made to accomplish the same result.

The cross-head is located to one side of the plane of the pinions, preferably the upper side, and arranged nearly tangential to the peripheries, and is of a width greater than the length of the teeth ofthe pinions. The teeth 7c are formed on that part opposite the teeth of the pinions, while the other part is iiat and rests upon the solid portion of the pinions, thereby preventing the ends of the head getting below the plane of the pinions and doing damage to the machine.

Lever L, pivoted midway its ends upon the frame, is provided with a double incline, Z, at its rear end, located within the path of a pair of tappets, M, secured to the axle by setscrews at a distance apart, so that they contact with the double incline and vibrate from right to left, thereby carrying the head K from IOO side to side and effecting a continuous movement of the grain-disks I, thus bringing the openings therein successively in register with the discharge-openings in the bottom of the hopper, from which the grain escapes to each side of the machine by means of the tubes h, and having spouts or runner-braces b.

To denote the place at which the grain is planted, indicators N are provided and keyed to the outer end of a shaft, N', mounted directly above the spouts b. Shaft N is rotated from the axle by means of sprocket-wheels d d', keyed to each, respectively, and joined by a sprocket-chain, (Z2. The parts are so disposed and proportioned that at the moment the grain is dropped into the soil the indicator contacts with the ground and makes an indentation, thus showing where the grain is planted. By this means it may be known when the planter is dropping grain out of check or line. To overcome this difficulty, and in order that the planter may be engaged to drop the grain in rows or check, the axle and wheels are thrown out of gear by the lever F, and the axle set forward or backward, as may be required, to effect the desired result. For this purpose a ratchet, O, is keyed upon the axle, and a lever, P, having apawl, p, engaging the ratchet, is sleeved upon the axle. By operating this lever l? the axle is turned independently of the wheels till the desired adjustment is effected, when the wheels and axle are clutched so as to revolve together.

The indicators are flat bars having lugs projecting laterally therefrom, through which the Shanks it or markers n project. Coil-springs n2 surround said shanks, and are located between the lugs and have points of resistance on the innermost lugs and stops, a, projecting laterally from the shanks. rlhese stops extend through slots in the bar and limit the movement of the markers and prevent their turning within the lugs. By this arrangement if the markers should impact against a hard substance they will yield, thus preventing damage to the machine.

Having thus described my inventon,what I claim, and desire to secure by Letters Patent, 1s-

1. In a planter, the combination of the frame, a hopper centrally supported thereon, discharge-spouts extending from the hopper to each side of the machine, grain-wheels located within the hopper for regulating the delivery of grain to the spouts, intermeshing pinions connected with the shafts of the grain-wheels, a vibrating lever having a cross-head arranged to extend laterally on each side of the lever, teeth fixedly secured to and extended at right angles from the ends of the cross-bar for alternately engaging with the teeth of the pinions, and an indicator to mark the point of discharge of the grain, substantially as and for the purposes set forth.

2. The combination, with the hopper, of shafts vertically journaled and having their upper ends projected through the bottom of the hopper and provided with grain-feeding wheels, intermeshing pinions keyed to said shafts, a vibrating lever, a cross-head secured to the end of the lever and projecting laterally therefrom on each side, teeth extending at right angles from opposite ends of said crosshead and adapted to have an alternate rising and falling movement to alternately engagethe pinions, substantially as set forth, and for the purpose specified.
