RIDING-CULTIVATOR.

Speccaton of Letters Patent.

Patented July 1, 1913.

Application led January 10, 1911. Serial No. 601,785.

To all whom t may concern Be it known that I, JAMES O. KENNEMER, a citizen of the United States of America, residing at Mullin, in the county of Mills and State of Texas, have invented new and useful Improvements in Riding-Cultivators, of which the following is a specification.

This invention relates to riding cultivators, and it has for its objects tof simplify and improve the construction and operation of this class of machines.

In order that a riding cultivator may be successfully use d for the cultivation of various crops, the parts of the device shall be capable of ample adjustment in order that each part may be placed independently of other parts in position for most thorough service.

To enable-such adjustments to be effected easily, quickly and conveniently is another object of the invention.

Vith 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 may be resorted to when desired.

In the drawings, Figure 1 is a side elevation of a cultivator constructed in accordance with the invention. Fig. 2 is a top plan view of the same. Fig. 3 is a rear elevation.

Corresponding parts in the several figures l are 4denoted by like characters of reference.

The frame of the machine includes side bars l, 1, the rear ends of which are connected with a broad cross bar 2 which may be described as constituting a platform. The front ends of the side bars are offset laterally to form brackets 3, 3 which are secured upon the sides of the tongue or draft member l. The side bars 1, l will be hereinafter described as the inner side bars to distinguish from the Outer side bars 5, 5, the rear ends of which are secured upon the front side of the cross bar orplatform 2 and the front ends of which are odset laterally to form ,brackets 6 secured upon the inner side bars adjacent to the front ends of the latter. The outer side bars 5 are thus kept suitably spaced from the inner side bars of the frame, as will be most clearly seen in Fig. 2 of the'drawings.

The forward end of the frame rests upon and is suitably connected with the front arch 7, the legs of which 7 are provided at their lower ends with outwardly extending spindles 8 upon which Vexternally screw threaded sleeves 9 are supported for rotation, said revolving screws being equipped' each with a worm gear 10, as best seen in Figs. '1 and 2. The outer ends of the spindles S are connected Yby means including inclined braces 11 with the rear part of the frame. Mounted upon the revolving screws 9 in engagement therewith are nuts 12 constituting boxes with which the bifurcated heads 13 at the front ends of the cultivator beams 14 are connected by vertically disposed pivots 15 to enable saidbeams to swing laterally in an approximately horizontal plane. Shafts 1G, which are suitably supported adjacent to the sides of the frame, arevprovided adjacent to their rear ends with cranks 17 which arey within convenientreach of the operator and whereby said shafts may be rotated. The shafts 16 are equipped with worms 18 meshing with the gears 10, which latter, by turning the shafts may be rotated, thus revolving the screws 9 and e'ect-ing lateral adjustment of the nuts or boxes 12 with which the front ends of the cultivator beamsare connected. The screws 9 may be of any desired length to'aliord sufficient scope of adjustment, and the parts will be safely retained in adjusted position owing t-o the employment of worm gear, as described.

A bar or evener 19 is pivotally supported upon the underside of the tongue 1, and said evener is provided at the ends thereof with depending draft bars 20 the lower ends of which are vconnected with the ends of the spindles 8 by means including resilient draft links 21 of suitable well known construction which, when draft is applied to the bars 20, will yield to some extent so as to cause the draft to be transmitted to the cultivator gradually instead of with a sudden jerky motion.

The cultivator beams 14 are preferably of metallic tubular construction, and in their manufacture ordinary iron pipe of suitable dimensions may be advantageously em-l ployed. Said beams are providedinterme- `diate their ends with sleeves or castings 22 which are firmly secured thereon, saidsleeves being formed with foot rests 23, and with` hooks 24. 'The inner and outer side `bars l and 5 at each side of the frame serve to support a longitudinally adjustable or movable base block 26 carrying a segment rack 27 upon which is fulcrumed a handlever 2S having a stop member 29"engaging said rack. Said levers, therebeing one at each side of the machine, are connected with the hooks 24 of the sleeves 22uponthe beams 14 bymeans including flexible elements, such as chains 30 and springs 31, thus causing the beams to be supported from the levers 23 with someV degree ofl resiliency, enabling the said cultivator beams to be Vvtilted or `adjusted in 'approximately vertical planes by means of the levers, the beams being capable of swinging vertically about the axes of the screws 9.

Aseat supporting frame 32 ispivotally connected with clips or clamping devices 33 which are adjustably mounted upon the side barsl of the cultivator'frame, said se'atsupporting frame including Irearwardly extending Iside bars 34 carrying a housing 35 in which a shaft '36 having an operating crank 37 is supported for rotation, said 'shaft having a threaded 'portion 3S engaging a nut 39 extending downwardly from the seat 40 whichis"mounted slidably upon' the housing where it will be seen that said seat may be "shifted or movedforwardly or rearwardly by simply' turning the screw threaded shaft,

thus disposing the seat Vat the' most `advantageous point for the` operator. The operatorin practice places his feetnpon the foot rests 23, thus enabling him when occasion Shall :demand to depress?thecultivator beams' against the tension of the supporting "springs 3l and also enabling the beams to be 'moved laterallyfif'itshall be desired to do s'owhile the machine is in operation.

'The'axle of the machineisl composed of the cranks 41 providedat their lo-werends with spindles uponwhich the wheels'42 lare bearing members 44 is right' and left threaded internally'for er'iga'gement with the screw threaded arms 43, Iand said sleeve is provided with an external wrench'seat. 46 to enable it to be conveniently'rotated, thus moving the :axle ,cranks in`wardly`or outwardly according to the direction of'r'otation, and

thereby regulating the ldistance between the supporting wheels 42, which latter may thus be spaced apart to suit the kind as well as `the condition of growth of the crop that is ltran"sporting wheels, thus excluding sand and dirt; said sand boxes are connected by links orconnecting rods 49 including turn buckles 50 with the downwardly extending arms 5l `of`a rock 'shaft 52l which is supported for oscillation in suitable bearings upo'n the frame of the machine. Said rock shaft is provided. with' a hand lever 53 having a'stop'member54 adapted to engage a segment rack 55 which is suitably supported upon the frame of the machine for the purposeof retaining the axle cranks vin any position to which they may be adjusted by the devices just described, thereby enabling the' entire frame of the machine to be raised and lowered relatively to the support-ing wheels. n

Each plow beam carries at its rear end` a frame or Vcasing 'GO wherein a standardGG having a plow carrying foot is vertically 'adjustable' byv simple means provided for the purpose. Means are also v'provided to permit the footto swing rearwardlywhen obstructions are encountered, but as these parts "are not'herein claimed,they will not be described in detail. Beam spacing members 85 are also provided, `thesame being fulcrumed on a supporting member 86 andl connected by links 89 with the T-head 90 of an adjusting lever 91.

Eframeof the -machine may be raised or lo'w-l ere'dwith reference to the supporting wheels, and the latte] may be spaced at various dis- :tan'ces apart. The plowcarrying standards lmay be'iadjus'ted axial-lyso as to present,w the blades in such 'a manner as to throw the dirt 1n various directions. AVertical adjustment of the-plow carrying standards may also be vreadily effected. The entire construction is simple, inexpensive and eminently VAsuitable vfor the purposes for which it is intended.

'Having thus described the invention, what is claimed as new, is

`1. 'In a cultivator, "a carrying frame, sleeves connected with the frame and constituting bearings,crankfaxles having screw tli `reade'd"arms suj'oportefd in the sleeves, said arms being r'espectn'fely yleft and right threaded, a left and right threaded sleeve disposed intermediate the bearing Sleeves and engaging the threaded arms of the axle cranks, said sleeve having a wrench seat, transporting Wheels upon the crank axles, and means for adjusting the crank axles and for supporting them in adjusted position to raise or lower t-he frame with relation to the transporting wheels.

2. In a cult-ivator, a carrying frame having bearing sleeves, crank axles having right and left threaded arms journaled in Said sleeves, a threaded sleeve engaging the right and left threaded arms and having a wrench seat, a rook shaft supported upon the earrying frame and having arms, members conneeting said arms with the crank axles, and means for oscillating the rook shaft and for securing it at various adjustments to adjust the crank axles.

3. In a cultivator, a carrying frame, a front arch connected therewith and having spindles, eultivator beams connected adjustably with the spindles, sleeves mounted upon the eultivator beams intermediate the ends thereof and having foot rests and upwardly extending hooks, base members supported upon the frame of the machine and having segment racks, levers pivoted upon the latter and having rack engaging eat-ches, and flexible connecting members including springs connecting the levers with the hooks extending from the sleeves upon the eultivator beams.

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