SPECIFICATION forming part of Letters Patent No. 576,400, dated February 2, 1897.

Application filed July 20, 1896.

To all whom, it T11/ay concern:

Be it known that I, SAMUEL FULTON, a citizen of the United States, residing at Alma, in the county of Harlan and State of Nebraska, have invented certain new and useful Improvements in Cultivators; 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.

My invention relates to improvements in that class of cultivators which are known as corn-listers, and its novelty and many advantages will be fully understood from the following description and claims when taken in conjunction with the annexed drawings, in which- Figure 1 is a plan view of my improved corn-lister. Fig. 2 is a rear elevation of the same. Fig. 3 is detail section taken in the plane indicated by the dotted line x of Fig. 1. Fig. 4 is a detail section taken in the plane indicated by the line y y of Fig. 3, and Fig.

5 isa detail enlarged section illustrating the manner in which the draw-bars are connected with the axle.

In the said drawings similar n umcrals designate corresponding parts in all of the several views, referring to which- 1 indicates the axle of my improved cultivator, which is preferably of a T form in crosssection and made of steel,and is provided at its ends with spindles 2 to receive the traveling and supporting wheels 3, and 4 indicates the tongue or pole, which is connected to the axle 1 and is designed for the attachment of the draft-animals. This tongue or pole 4ris preferably employed in my improved cultivator, as under ordinary conditions two draft-animals will be necessary to draw the cultivator. It is obvious, however, that when desired the tongue or pole may be dispensed with and ordinary thills employed in lieu of the same. I have also shown one of the traveling and supporting wheels 3 as provided on its hub with a gear-wheel 5, and I have also shown a portion of a shaft equipped with a pinion engaging the gear-wheel 5. Thisgearing is designed to operate a seed-dropper (not illustrated) which may be of any ordinary construction, and when the seed-dropper is not Serial No. 599,924. (No model.)

employed on lthe cultivator the gearing may axle with straps 9, through which the bars 7 extend and in which they are loosely and adjustably secured by the pins 10, which take through the straps 9 and the apertures 8 of the bars 7, as shown.

The bars 7 carry the bales 11, which have their horizontal cross-bars connected to the rear` ends of said bars 7, and also have bearings 12 at the free ends of their depending arms 13 to receive the shafts 14 of the disks 15. It will thus be seen that the bails 11 form vertically-movable bearin gs for a purpose presently described. The shafts 14 are hori- Zontal and are so arranged with respect to each other that they describe an obtuse angle, and they each carry three (more or less) disks 15, which are increased in diameter as they approach the middle of the cultivator. The disks 15 serve in conjunction to form a single furrow, and by reason of the disposition of the shafts 14 the disks on one shaft will throw the earth in one direction and the disks on the other shaft will throw it in the opposite direction. The disks are increased in diameter toward the middle of the cultivator, as shown, in order to form a furrow of proper depth and yetavoid the objectionable necessity of piling the earth high between furrows. V

20 indicates a cross-bar which is mounted and secured to the bars 7, and 21 indicates a seat which is arranged in rear of the bar 20, and is connected with the tongue 4 by a preferably resilient strap 22, which in turn is connected to the bar 20 by bars, as 23. Thus it will be seen that when the driver is in his place his weight will loe imposed on the bar 20, and consequently on the bars 7 and the disks 15, so as to sink the latter the proper intervals in their length and byproviding the IOO distance in the ground and normally retain them in such position for the purpose before described. While the disks 15 are sunk in the ground during the operation of the lister, it is necessary when the lister is to be turned or moved from place to place to raise the disks 15 out of the ground and retain them in such position. To this end I provide the bell-crank levers 25, which are connected to the cross-bars of the bails 11 and are fulcrumed on the bars G,the peripherally-grooved segments 20, fixed to said levers, the pedallevers 29, which are fulcrumed in advance of the bell-crank levers and extend rearwardly to a position below the seat 2l, where they have pedals 27, and the chains 28, which are connected to the levers 25 and take over the segments 2G and are connected at their opposite ends to the levers 29, as shown. In virtue of this construction it will be perceived that the driver by rising from the seat 21 and standing upon the levers 29 will remove his weight from the disks 15, and such weight,through the medium of the levers 29, will raise the disks 15 to a position above the ground, so as not to interfere with the travel or turning of the lister. To hold the disks 15 in their raised position, the upright arms of the bell-crank levers 25 are provided with detents 30, designed to engage racks 31, ixed on the bars 6, and the upright arms of the bell-crank levers are preferably provided with a handle, whereby they may be readily rocked to lower the disks 15 and also to assist in raising the same when desired.

33 indicates a shovel which is designed and adapted to raise the earth 'lying between the paths of the two inner disks 15. This shovel is connected by a shank Si with the bar 20, and it will therefore be seen that it will be raised and lowered with said bar 2O and the disks 15, for the purpose before described.

With all of its advantages it will be seen that my improved corn-lister is very simple and that the imposition of the weight of the driver on the disks to sink the same into the ground permits of the cultivator being made light in weight and consequently cheap, which is an important advantage and a desideratum in this class of machines.

IIaving described my invention, what I claim, and desire to secure by Letters Patent, 1s-

1. In a cultvator for the purpose described, the. combination of an axle having traveling wheels at its ends, the bars 6, fixedly connected to and extending rearwardly from the axle, the bars 7, connected to the axle in such manner as to permit of their rear ends being moved vertically, the cross-bar 20, connected to the several bars 7, the drivers seat connected with said cross-bar 20, the bails having horizontal cross-bars connected to the rear ends of the bars 7, and also having depending arms provided with bearings at their lower ends, the shafts j ournaled in said bearings and carrying disks, the bell-crank levers fulcrumed on the bars 6, and connected to the cross-bars of the bails 11, segments 26,

. fixed to said levers, the pedal-levers 29, fulcrumed in advance of the bell-crank levers and extending rearwardly to a position adjacent to the drivers seat and having pedals, the chains connected to the bell-crank levers and taking over the segments and connected to the pedal-levers, and means for adjustably fixing the bell-crank levers, substantially as and for the purpose set forth.

2. In a cu-ltivatorforthe purpose described, the combination of an axle having traveling wheels at its ends, vertically-movable bearn ings connected with the axle and arranged in rear thereof, shafts journaled in said bearings and carrying disks, a drivers-seat support connected with and extending rearwardly from the axle and carrying a drivers seat at rear end, a connection between said seat-support and the vertically-movable bearings of the disk-shafts, the bell-crank levers connected with the verticallyemovable bearings and f ulcrumed on supports connected to the axle, the segments fixedly connected to the bell-crank levers, the pedal-levers connected to the bell-crank levers, the pedallevers connected to supports in rear of the axle and extending to the points adjacent to the drivers seat, and chains connecting the bell-crank levers and pedal-levers and taking over the segments, substantially as and for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.
