CORN-PLANTER.

SPECIFICATION forming part of Letters Patent No. 424,240, dated March 25, 1890.

Application filed May 16, 1889- Serial No. 310,947- (No model.)

To all whom, it nmyconcerh:

Be it known that LJACOB \VISE, a citizen of the United States, and a resident of Daretown, Salem county, New Jersey, have invented certain Improvements in Corn-Planting Machines, of which the following is a specification.

My invention relates to that class of seedplanting machines in which a measured quantity of seed is intermittently fed from a hopper and deposited at regular intervals in a furrow cut by the machine; and it consists of certain improvements in the construction of the operating parts of the machine, as more fully described hereinafter.

In the accompanyingdrawings, Figure 1 is a longitudinal sectional elevation of a seedwith my invention with the various parts in operative position, some of the parts being enlarged to more clearly illustrate the construction of the machine. Fig. 2 is a similar view with the parts in a different position, to which they maybe moved while the machine is traveling to or from the field of operation. Fig. 3 is a plan View of the machine with the parts in the position shown in Fig. 1, a portion of the superstructure being removed for the purpose of illustrating more clearly the construction of the machine. Fig. i is a sectional plan view of one of the feedhoppers, and Fig. 5 is a face View of a portion of the hopperdischarge-actuating mechanism.

The machine as now constructed is especially designed for planting corn, and it is provided with suitable devices for cutting a furrow in the ground, for dropping a certain quantity of corn at previously-determined i11- tervals, and with devices for closing the furrow and covering the corn with earth, and a smoothing-roller for pressing the loose earth upon the seed.

A is a suitable frame carrying the various operating parts of the machine, to the front end of which is attached a draft-pole A, of any ordinary construction, and the whole is supported by wheels B. This frame A may be of'awidth suflicient to support any number of sets of hoppers and seeddistributing. de vices, of which I have shown two in the accompanying drawings; but as their construction and operation is precisely the same the description will be confined to one set. The hopper O is divided into two compartments by a central partition 0, the corn or other seed to be planted being placed 111 the compartment 0 and a suitable manure being placed in theother compartment 0. Each compartment of the hopper C inclines toward a central opening (1 in its lower portion, and in the lower portion of the hopper-frame, below the opening cl, is a slide 6, having an opening or port 'd' below each of the central mouths of the hopper, said slide being rec procated in such a manner as to present its port d alternately at the mouth (Z and at the upper end of a depending tube G, suitably secured to the hopper-frame, the lower end of this tube opening into a vertical spout H. The slide 6 is made of sufficient width to contain the delivery-ports (1 under the openings din the seed-compartment and in the manure-compartment of the hopper, but is reduced in width and is provided with an extension e at its rear end, which projects beyond the body of the hopper for a short dis tance, and is adapted to be acted upon by a rotating cam E, the camacting to push the ports (1 of the slide from beneath the openings d to a position iinmediately above the tube G, into which any seed contained in the port d will fall. The slide is retracted after each operation of the cam E by coiled springs g, one end of each spring being secured to the slide E and the other end being held by the hopper-frame.

The cam E is rotated from the main axis of the machine by the mechanism more clearly shown in Fig. 5, consisting of the gear-wheel I, secured to the shaft A a.pini on I, secured to the shaft E, to which the cam is keyed, and an intermediate gear J, carried by a frame J, hung to the shaft A and having its outer end under the control of a suitable hand-leverj. The gears J andl are at all times in contact with each other; but the gear I is only moved into contact with the pinion I when it is desired to operate the cam E, the-cam J 2 being then moved to the position shown in full lines. On mov ng this cam, however, to the dotted-l1ne position the gears I and J are thrown out of contact with too each other and the cam-shaft is not rotated. By this mechanism the port (1 is filled with seed from the hopper each time it is presented at its lower mouth d, and it is made of such a size as to receive any measure or quantity of seed which it may be desired to plant at one operation, and this quantity is delivered at each forward movement of the slide to the tube G, and from thence through the spout H to the ground. The diameter of the wheels 13 and the relative diameters of the intervening operating-gear between the shaft A and the shaft E is such that the cam E is rotated and operates upon the slides e at suitable intervals, so that the seed and manure in the hoppers are delivered at equal dis tances apart, this operation being particularly well adapted to corn-planting, where it is desirable that the growths of the corn should be at equal distances each from the other for the purpose of cultivation.

The hopper is provided with a hinged lid 0 and the Whole hopper-frame is pivoted to the frame-work of the machine at f, so that it may be swung upward upon its frame to examine, repair, and cleanse the operating mechanism.

In front of the tube H is placed a cultivator tooth or blade h, having a projecting blade or tongue it, These parts act to cut a furrow in the ground immediately in front of the tube H, and at the rear of this tube are placed in their respective order covering-blades K and a smoothing or pressing roller L, which operate to cover the seed delivered from the tube H and to press the loose earth upon the same. A lever m is suitably mounted upon a stud fixed to a bearing n, projecting from the rear of the tube H, and is connected at its lower end to the rear of a valve M, sliding in the tube Hnear its lower end. The upper end of this lever m is connected to a similar lever 91, suitably mounted upon a stud held in a bearing 02 fixed to the rear of the tube H. The upper end of the lever 72 projects into the path of the cam E, and is operated upon by said cam at each rotation of the same after it has accomplished the forward movement of the slide 6, so that the seed delivered through the tube G to the spout H first falls upon the slide M, and as the cam continues its rotary movement the lever 71 is operated upon and effects the withdrawal of the slide M from the spout H, allowing the seed which rests thereon to drop into the f urrow cut by the tooth h and tongue h.

The spout H is pivoted at its upper forward end to the frame-work of the machine at h and has connected to its front portion a flat bar K, the opposite end of which is secured to a shaft L, mounted in the framework at the forward end of the machine. This bar K is made in two sections 7t connected by a rule-joint k of such a character as to form a practically rigid bar while in the position shown in Fig. 1, and permitting a movement in but one direction, the parts when so operated assuming the position shown in Fig. 2, so as to lift the spout H and its furrow-forming blade out of operative position.

An arm P is secured to the shaft L at the front of the machine, and is connected by a rod p to an operating-lever Q at the rear portion of the machinein a convenient position for manipulation by the attendant.

The scraping and covering blades K are held upon a dependent frame R, pivoted at its upper end to the frame-work of the machine at 71 and to an extension of the frame R at the rear of the scraping-blades is pivoted the roll-carrying frame B. At the pivot-point of the frames R R are attached one or more connecting-rods S, the upper ends of which are attached to arms 3, suitably secured to a shaft onto which the operating-lever Q is keyed. It will thus be seen that by manipulating the lever Q the spout H will be swung forward upon its pivot through the medium of the connecting-rod p, the arm P, and the bar K to the position shown in Fig. 2, while the scraping-blades and roller Will be simultaneously lifted through the medium of the connecting-rods S and arms 8.

Any suitable retaining device having a number of notches may be employed to retain the operating-lever Q in its two positions, and similar retaining devices may also be employed for the lever J 1 At the rear of the frame-work are markers w, of any ordinary construction, carried by a dependent frame w, capable of lateral adjustment thereon, so that they may be moved to a suitable position for marking the next row.

I claim as my invention The combination, in a corn-planting machine, of the frame A, the hopper-frame pivoted thereto and carrying on its under side an inclined spout G, the seed and manure hoppers placed side by side upon said frame, and the ported slide e, guided in the lower portion of said hopper-frame, the hopperports cl, and the cam E, for effecting the reciprocation of the ported slide between the hopper-openings and the spout, the seed-delivery tube H, pivoted at its upper end to the frame A, the valve M therein, and means for actuating the same, the f urrowingtooth and guiding-blade therefor secured tothe lower end of said tube H, the covering-blades K in the rear of said tube, and the smoothing-roller L, carried by the frame, all acting substan: tially as and in the manner set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
