CORN-PLANTER.

SPECIFICATION forming part Of Letters Patent-NO. 438,058, dated October '7, 1890.

Application iled April 23, 1890. Serial No. 349,080. (No model.)

To all whom it may concern:

Be it knownthat I, KNUT BULAND, of Linn Grove, in the county of Buena Vista and State of Iowa, have invented a new and useful Improvement in Corn-Planters, of which the following is a full, clear, and exact description` r My invention relates to an improvement in corn-planters, and has for its object to provide an implement of simple and durable construction and one wherein the runners may be adj ustedvertically, as desired, and in which the ordinary form of marker is dispensed with.

The invention consists in the novel construction and combination of the severalparts, as will be hereinafter fully set forth, and pointed out in the claim.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar figures of reference indicate corresponding parts in all the views.

Figure 1 is a central longitudinal section through the machine. Fig. 2 is a plan View. Fig. 3 is a transverse section taken near the axle. Figa is a detail sectional view illustrating the peculiar construction of the dropslide, and Fig: 5 is a detail perspective view of one of the supporting-wheels of the machine.

The frame consists of two side pieces 10, connected by cross-bars 11, 12, 13, 14, and 15, and the said frame thus constructed is mounted upon an axle 16, to the outer ends of which the supporting-wheels 17 are rigidly secured.

The drivers seat 17 f is preferably supported by attachment to the cross bars or beams l1 and 12, and to the extremities of a transverse rod or bar 18, attached to the forward portion of the frame, the forward ends of the runners 19 are pivoted, the said runners being located outside of the frame. The vertical standards 20- of the said runners, located at the rear ends, are attached to a rod 21, extending across the frame.

The rod 21 has attached thereto, at ornear its center, one end of a link 22, which link is pivoted at its other end to a lever 23, fulcrumed, preferably, upon the cross-bar 13, which lever is provided with any approved form of thumb-latch 24, adapted for attachment with a rack 25, as best shown in Fig. 1.

its under face, a lever 26 is centrally fulcrumed. Upon the axle 16 pins 27 and 2S are secured, one of which extends upward and the other downward, and the said pins are so located that as the axle revolves they will alternately engage with the ends of the lever 26. The relative positions of the pins to the lever are best illustrated in Fig. 3.

The seed-boxes 29 may be of any suitable or approved construction, and likewise the. drop-bar 30 held to slide in the seed-boxes.` The drop-bar, however, is actuated in a peculiar manner, which consists in attaching chains 31 to pins 32, fast to the under side of the drop-bar, one at each side of its center, as shown in Fig. 2. These chains pass over guide-pulleys 33,journaled, preferably, upon the cross-bar 14, and the rear ends of the said chains are attached to the extremities of the lever 26, as best shown in Fig. 2, in which it will be observed that two chains only are ernployed.

The supporting-wheels 17 are also of peculiar construction, which is best illustrated in Fig. 5, the said supporting-wheels being made up ordinarily of two spaced metal tires 34, which are connected to the hub 35 by spokes 36, the said spokes being bifurcated at their outer ends, as illustrated at 37, and at intervals upon the periphery of the supportingwheels transverse plates 38,are attached, the said plates being so spaced that as the machine is drawn forward and the seed dropped one of the plates will press the earth down at each hill and mark the location thereof. Thus itwill be observed that by means of this simple attachment to the wheels the usual cumbersome markers may be dispensed with.

In the operation of the machine the runners may be raised or lowered to produce a deep or a shallow furrow and elevated quite high when it is necessary to turn corners. As the machine advances and the axle is rotated, the pins 27 and 28, alternately engaging with the ends of the lever 26, act through the medium of the chains 31 upon the drop slide or bar 30 to regularly laterally reciprocate it.

I desire it to be distinctly understood that while specilic construction has been shown ICO and described I do not confine myself thereto, as other equivalent construction may be elnployed without departing from the spirit of the invention-as, for instance, the side bars of the frame may be connected by a greater or a less number of cross bars or beams, and the lever 23 may be differently located.

In order that the markers 38 may register properly with the marks previously made upon the soil, I employ a device attached to the extremity of the frame of the machine, whereby the drive-wheels may be shifted from side to side as demanded. This device preferably consists of a lever 40, pivoted at its inner end to about the center of the rear cross-bar 11 of the machine. To the said lever the upper end of a pendent post 41 is pivoted, the said post being preferably pivoted to the lever considerably nearer its inner than its outer end, and the said lever, upon its under edge near the outer end, is provided with an attached hook 42. One end of a chain 43 is secured to the post 41 near its lower end, the other or upper end of the chain being adapted for engagement with the hook 42.

In the operation of laterally adjusting the wheels the post 41 is dropped down to the position shown in positive lines'in Fig. 1 and its base made to rest upon the ground. The operator then bears down upon the outer end of the lever 40 until the rear portion of the frame of the machine is sufficiently elevated to cause the wheels to clear theground, and when this is accomplished the wheels are held in this position by taking up the chain 43 and attaching one of its links to the hook 42. The wheels may now be carried either to the right or to the left by pushing upon the lever 40, the post 41 acting as a fulcrum. When the marker has registered properly with the last ldepression in the soil, the chain is loosened and the wheels suffered to drop in contact with the ground. When this lifting attachment is not in use, it may be carried up to the position shown in dotted lines in Fig. 1 and secured in any suitable or approved manner to the drivers seat.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- The combination, with the frame, the axle having pins 27 28, the marking-Wheels, and the transverse seed-slide 30, of the transverse centrally-pivoted lever 26, With its ends in the paths of said pins, pulleys 33, mounted on the frame in rear of the seed-slide, and two chains 31, passing from the ends of the lever 26 forward around pulleys 33 and inward to the slide and secured thereto at 32 32, substantially as set forth.

KNUT BULAND.
