Specification of-Letters Patent.

Application filed August 12, 1918. Serial "No. 249,404. 7

To all whom it may concern: Be it known that I, EDWARD W. OWENS, a citizen of the United States, and a resident of Wagner, in the county of Charles Mix and State of South Dakota, have invented certain new and useful Improvements in Cultivators, of which the following .is a specification.

The present invention aims primarily, to provide an improved three row cultivator.

A further object of the invention is the production of a cultivator embodying improved means for shifting the cultivator tl16' production of a three row 'cultivator. so constructed that the supporting wheels travel on'oppo'site sides of the center one of v V V frame, the rear ends of the arms being sethree rows of corn.

. Furthermore, the invention contemplates V av three row cultivator embodying an improved draft rigging.

Still another object of the invention is the production of a three row corn-cultivator, comparatively light in weight and inex pensive in construction, yet thoroughly durable and efiicient in operation.

. 'With these and other objects in view, the

ing

invention consisting in the construction, combination, and novel arrangement of parts will be fully understood from the following description, reference being had to the accompanying drawings which form a part of this application, and in which like characters of reference indicate correspondwhic h Figure 1 a plan of a cultlvatorconstructedin accordance with the invention;

'While. I have illustrated and hereinafter described the preferred embodiment of the lnventlon, I would not be understood asbeing limited' tothe specific structure chosen for lllustrat on, for various alterations and modifications may bje'made in the details of construct onand arrangement of parts without departing from the spirit and scope of the invention as claims. v

Referrlng now to the illustrations, the

defined in the appended intermediate longitudinal members, 12. The frame is reinforced by a V-shaped' bar, 13, whlch rests upon and is secured to the cured adj acentthe rear corners ofthe frame and the apex of said V-shaped' barbei'ngpositioned forwardof. the center of the front cross member and secured to a plate, 14, be-

' low which is the front truck embodying a bolster, 15, pivoted to the plate, 14, as by a king-bolt, 16, the bolster being provided with forks, 17, in which are'journaled travel wheels, 18. To the bolster is secured a suit- .1 laterally in oppositedirections as at, Y22, and 'on the said extended portions are journ'aled travel wheels, 23. The extreme ends of the axle arms are rotatably' supported in the lower ends of bars, 24, 'the'u-pper ends of which are pivoted as at 25, to; the main frame.. To the under sideof the interma diate frame members, 12, are pivoted bars,

26, the other ends of which are vadjustably secured to't'he bars, 24, to hold the latter against forward and rearward movement.

It is evident thejmachine may-be. raised or lowered. on the travel. wheel's by accordingly shifting the point of connection between the bars, 26'and 24.

The travel wheels, 23, are sof disposed as to travel on opposite sides of the center of three rows'of-corn represented by the dotted lines, 27.- i i The machine is provided with six gangs of cultivator plows or other earth working machine consists, essentially, of a main frame, preferablyincluding front and rear 7 cross members,=9 and 10, respectively, interconnected by suitable side members, 11, and" ing the pair of beams.

devices, the two intermediate gangs being so positioned as to turn the soil on opposite sides of the center corn row and the other gangs being positioned outside the travel wheels to cultivate the outer rows, and each gang includesv a pair of interconnected beams, 28, carrying plows or other earth Working devices, 29, the-forward ends of the beams being pivotally secured to suitable,

bracket arms, 30, depending from the forward cross member. Means are provided for holding the shovels in yieldable engage- -ment with the earth and for raising the beams. For this purpose I provide for each gang an upright, 31, the lower end of which freely penetrates a member, 32, interconnect- Two rock-shafts, 33, are provided, for

controlling the uprights, one for each three gangs. The said shafts are 'journaled in bearings, 34, mounted on the frame. The shafts carry cranlcarms, 35, pivoted respectively to the upper ends of. the uprights.

The shafts are actuated by levers, 36, fulcrumed on quadrants, 37, and provided with detents, 38, engageable with the quadrants to hold the levers in any desired positions.

1 Between the members, 32, and shoulders,

39, on the uprights, 31, are interposed compression-springs, 40, and the lower ends of the uprights are provided'with heads or bosses, 41, to raise the beams when the levers, 36, are depressed. When the said levers are raised it is evident the compressionsprings, 40, will hold the plow yieldably engaged in the earth. 7

To afford means for simultaneously shift- 1 ing the rear ends of the beams laterally to correct the positions ofthe earth working devices with respect to the rows of corn, I

provide mechanism preferably consisting of a bar, 42, slidable adjacent the rear face of the rear cross member, 10, in suitable guides consisting of U-shaped members, 43, secured beams, 28.

to the cross member, 10, and slidably inclosing the bar, 42. The bar, 42, is provided with longitudinal slots, 44, and the portions of thebar at the upper edges of the slots travel on friction-rollers, 45 rotating on 7 said braces preferably being positionedon the sides of the rods remote from the adjacent corn rows. For shifting the bar I provide two foot-power actuated devices mounted on the longitudinal frame members, l2 and consisting of longitudinallydisposed tubular shafts, 48, rotatable on rods, 49, supported by rear bearings, 50, mounted on the rear cross member, and front bearings, 51, mounted on the longitudinal members, 12, and havingdepending forks, 52, between which are free to move vertically the forward end portions of footlevers, 53. To the ends of the said foot levers are secured flexible links, 54,, passing around direction pulleys, 55, journaled in the forks, 52, and wound on the front ends of the tubular shafts, 48, or upon drums, 56, thereon. To the intermediate portions of] the levers, 53, aresecured flexible, links, 57, which are wound upon the rear portions of the shafts, 48, or upon drums, 58, thereon, and secured to the arm, 47.

The rods, 49, are extended toward each other from the bearings, 50, and are then extended rearwardly as at, 59, andonthe said extended portions is mounted the drivers'seat, 60. I

By virtue of this construction it is evident that as one of the foot-levers, 53, is. depressed at its rear end, the associated link being wound upon the shaft, 48, willrotate the latter and co-act withthe arm,47, in

shifting the bar, 42, in the direction of the depressed lever. As the'rear' end of the foot-lever is depressed the front end thereof rises and co-aots with the link, 57,,in drawing the arm, 47 i The draft rigging preferably consistsof a cable, chain or'other flexible element, 61, positioned belowthefront cross member, 9, and having its end portions passing around direction-pulleys, 62, mounted on a flange, 63, depending from the cross member, 9; and extended forwardly through the flange. The extreme ends of the flexibleelement, 61, areprovided with books, 64, or other suitable means for attachment to'whifile-trees, 65, or other devices, to. which draft animals may be hitched. This'draft rigging thus affords means for. equalizing the draft.

It isclear that in the construction now disclosed the driver can have no difficulty watching hisalinement, inasmuch as he is seated directly over the center row Having thus. described my invention,
