CHECK-ROW CORN-PLANTER.

Specicaton of Letters Patent.

Patented Feb. 13, 1906.

Application filed December 4, 1905. Serial No. 290.267.

To all whom t may con/cern:

Be it known that I, JOHN LEE MILLER, a citizen ofthe United States, residing at Wood River, in the county of Hall and State of Nebraska, have invented a new and useful Check-R ow Corn-Planter, of which the following is a specification.

This invention relates to check-row cornplanters and the objects of the invention are to simplify and improve the construction and operation of this class of machines and to insure perfect regularity in the process of planting, so that the seed shall be deposited in hills located at equal distances apart throughout the field without regard to such inequalities as may exist in the surface of the land.

With these and other ends in View, which will readily appear as the nature of the invention is better understood, the same consists in the improved construction and novel arrangement and combination of parts, which will be hereinafter fully described, and particularly pointed out in the claims.

In the accompanying drawings has been illustrated a simple and preferred form of the invention, it being, however, understood that no limitation is necessarily made to the precise structural details therein exhibited, but that changes, alterations, and modifications within the scope of the invention maybe made when desired.

In the drawings, Figure 1 is a longitudinal sectional view of a check-row corn-planter constructed in accordance with the principles of the invention. view of the same. Fig. 3 is a transverse vertical sectional view taken in front of the axle and looking in a rearward direction, and Fig. 4 is a perspective detail view.

Corresponding parts in the several figures are indicated throughout by similar characters of reference.

In the construction of this improved cornplanter there is employed a main or wheel frame A, in the construction of which are included side members 1 1 and a rear bar 2, serving to space and connect the side members. The latter are connected securely with the side members 3 of an arched axle B, which is constructed in the usual manner with spindles 4, upon which the transporting-wheels 5 are supported for rotation.

In connection `with the outer frame A there is used an inner frame C, comprising side members 6 6, spaced and connected by a rear cross-bar 7. This inner frame supports near Fig. 2 is a top plan.

its front end a cross-bar 8, which is extended beyond the side members of the outer frame and which carries the seedboxes or hoppers 9 and the runners or furrow-openers 10. The hoppers receive the ends of a transverse shaft 11, that serves to actuate the seed-dropping mechanism, which may be of any desired construction and which has not been illustrated, as it forms no part of the present invention.

Upon the side members of the outer frame are supported uprights 12, the upper ends of which are curved forwardly to constitute segment-racks 13, the upper terminals of which are connected with the arched portion of the axle-beam adjacent to the side members 3 of the latter. Said side members are provided with studs 14, upon which are pivoted handlevers 15, having spring-actuated stop members 16, engaging the segment-racks. Connected with the levers 15 are link-rods 17, which extend through plates 18, connected with the side members 6 of the inner frame by means of upright bolt members 19, securely connected with the side members 6 of the inner frame and serving as guides for the vertically-sliding plates 20, which are fixed upon the lower ends of the link-rods 17. Springs 21 are coiled upon said link-rods between the plates 18 and 20, said springs serving to resiliently support the weight of the rear portion of the frame O.

The frame C is provided with boxes 22, supporting a transverse axle or shaft 23, carrying a ground-engaging wheel 24, which is provided with equidistantly-disposed markers 25. The latter are embedded in the rim of the wheel 24, and said markers, as well as the rim of the wheel, are made concave and engaged by a scraper 26, supported upon the rear cross-bar 7 of the frame C for the purpose of keeping the periphery of the wheel, as Well as the marking devices, free from adhering dirt. This is extremely important, for the reason that it is the periphery of the ground-engaging wheel 24 which determines the distance between the hills, and any substance adhering to the periphery of said wheel would cause an undesirable deviation. The Wheel 24 is fixed upon the axle 23, which latter rotates in the boxes 22. The shaft 23 carries a sprocket-wheel 27, which is connected by a link belt 28 with a sprocket-wheel or idler 29, supported for rotation bya shaft 30, near the front end of the frame O. The upper lead of the link belt 28 engages a disk 31, mounted upon the operating-shaft 11 said IOO IIO

' disk being provided with a plurality of pairs of radially-extending armsBZ, thatl are adaptr ed to be yintermittently engaged by tappets 33, connectedat intervals with the links of. the chain or belt 2S. The tappet-carrying links may be variously spaced in the chain or link belt according to the frequency, with which it is desired to actuatethe operating'- shaft, it being understood that at each operation ot the latter the seed-dropping mechanismwillsbe actuatedr The side members 1e 1a of thai-ramena areV provided with forwardly-extending brackets 35,.aifordingbearings-.for the shaft 111.,.which extends intothe hoppersA and:` operates theseededropping mechanism.. 'Ehe cross-bar; 8,

which. connects theiront ends of. the. side:

membersv ot the frame. C, is. provided with upwardly-extending brackets 36: that are pivotedv uponi the shaft L1, which. latter thus serves to form a. hinge connectionv between the frames Ai andi Cs The tongue or. draft bar 37X is secured upon' the. crossfbar` 8V and upon.y a: cross-b ari38, which connectsthe-front endsiof, the runners. Said tongue is extend ed rearwardly andis. connected by means of a link 39 with an arm, 403 extending, from a rock-shaiit 41', which-.issupported earings upon` the side members of the. frame. A,.`said' rock-shait being provided with a. hand-lever 42', whereby it may bel operated. The lever 42. has a stopf member 43, adapted toengage a rack-segment 44, whereby said lever and its related parts'l mayV be secured at various ad.- justments.

By'manipuliating the. lever' 42. it will be readily seen that the front end ot they trame C, with the runners carried by said trame., may be raised orlowered, as may be desired, the front end of the tongue bein supported by the. team to form a ulcrum. -t the same time the rear end of the trame C,carrying the operating-wheelI 24, is capable: of independent adjustment by the means provided for the purpose, as hereinbefore described.

As will be seen Jfrom the foregoing description, the construction of thisiniproved cornplanter is very simple. rlhe planting mechan ism may be thrown out of' operation by simply elevating the rear end of the Jframe C by the means herein described until the Wheel 24 is supported beyond the possibility of contacting with the ground. The marking members 25 uponk the wheel 24 are disposed so as tov make indentations in the ground in alinement with the hills Where the seeds are dropped, and it is obvious that said marking members by forming such indentations will enable the driver or operator to satisfy himself at any timethat the machine is operating in perfect alinement.. l

Having thus described' the invention, what `isvclaimed is- 1. A main frame having an arched axle and transporting-wheels upon the latter, uprights supported upon the side members of the frame and? having rack-segments connected with the axle7 levers pivoted upon the side 'members of the axle-archand having s-top= members engaging the rack segments an auxiliary trame-having an. earthfengagingop.-
