SZPECIFICATION forming part of Letters Patent No. 629,499, dated July 25, 1899.

l Application tiled February 1'7, 1899. Serial No. 705,840. (No-model.) I

To ctZZ whom t 11i/(ty concern:

Be itknown that we, STEPHEN Il. GARS/r and DUDLEY GARsT, citizens ofthe United States, residing at Detroit, inthe county of Wayne and State of Michigan, have invented certain new and useful Improvements in Cultivators, of which the following is a specification, reference bein ghad therein 'to the accompanying drawings. y'

The invention has reference to riding-cultivators, and relates particularly to that class wherein the axles for the carrying-wheels are adapted to be shifted so that the said wheels may be inclined at will to the'right or left,v

causing the machine to move at an angle to the linev of draft forth'e purpose'of more thoroughly cultivating the growing crop and to avoid any irregularities or obstructions in the ground.

One of the objects of our invention is to.

' provide an improved shifting'mechanism for the axles adapted to carry the driver and tol be operated by the latter from his seat, the construction of the mechanism being vsuch that the latter willvv alwaysbe inA parallelism to the wheels, whereby the driver will be'constantly facing in the direction in which' the machine is traveling, and thus better enabled to control the movements ofY the cultivator.` Another object of our invention is to provide means whereby the driver' may from his seat and by t-he use of a properY shiftingdevice move the plow-sections simultaneously either to or away from each other and'to so form the shiftingdevicc that the latter vand the plow-sections will operate insubstantially hereinafter described, andshown in the draw-l ings, `in which- .l ,v 1

Figure lisa plan View of a c ultivator, par-` tiall'yl broken away to illustrate some of the essential parts. v Fig. 2 is a longitudinal sec-v tion taken on line :c fc, Fig. l. Fig. 3 is a view the cultivator, consisting ofy a central crossbar a, front cross-bar l), the bars closet at an angle to each other, andbraces'cl, the parts being arranged asv shown in Fig'. l and secured to each other inany approved manner.

The central bar ct carriesy ldeper'niin'g therev from at each en d av bracket B, in which are v,')ournaled the pivoted; axles C, more fully hereinafter described. A brace-rod e connects the lower end ofeach bracket to one of the bars c, vwhereby a rigid structure is obtained which carries the movable` parts of the cultivator.

Fig. 4 is a sectional viewl f The axles C, just'referred to, arepreferably L- shape'd in conflguratiomcomprisingin their construction theaxlepropeijf, and the pivot -pin or bang, thelatter device being adapted Vto engage .thebracket, as shown, and to. ex-

, tend 11p-and through thecentral cross-bar of -th'erigid'fra'me rlhe axles are retained with-l fin thebracketsby means of smaller brackets ,n y D, 'which engage the pinsbetween the crossbara and bearing t', formed on the brackets B, vandare iixedly secured to the pins by `snit` The brackets D, just described, comprise a rearu-'ardly-extendin g body portion E and forwardlyextending arms F, and to the 'body portion of the brackets is secured a movable frame G, which Vconstitutes our limproved shiftingdevice for the pivoted axles.' In con'n struction the frame consists of side bars k and 'y a cross-bar Z, on which is mounted, at the middle thereof, a seat H for the'driver.- The'sidey bars-are secured to the bracketsby bolts'm,

Fig. f2, which engage pairs of vertically-arranged apertures o within the bracket-body. This permits the frame to be adjusted vertically in the brackets. By this construction of mechanism the operator is enabled, by pushing upon the plow-sections I, to shift the movable frame from one side to another to ineline the wheels for the purpose before set` forth, leaving his hands free for driving and for operating the plow-sections. Likewise the driverbein g carried by the movable frame which is constantly in parallelism with the wheels of the machine is always facing in the direction in which the wheels are moving, which enables him to more effectively operate the cultivator.

The mechanism for spreading the plow-sections or forlmoving the lattercloser together is located upon the cross-bar J', which connects the free ends of the forwardly-extending arms F. In construction this mechanism comprises a gear-segment q, fixedly secured to the cross-bar referred to, and a shifting device in the form of a lever K, having a pivotal connection therewith. This lever is provided with the usual spring-actuated latch r,

`the hand piece s for operating the same, and

two clips tu, Fig. 4:, which are swiveled thereto, as shown.

L designates theusual plow-beams, which have a pivotal connection with the forward portion ofthe stationary frame A, and these carry the plow-sections I, before referred to,

saidsections each comprisingagroup of plows or a gang. Upon each section is located an upright'o, and a link w connects the upright with one of the clips upon the lever K. The Shifting lever extends rearwardly a su fticient distance, so that the driver is readily enabled to reach the same from his seat on the movable frame, and by moving the lever the driver actuates simultaneously the two plow-sections, bringing `them nearer together or spreading the same, according to the direction inv which the shifting device is moved. served from this construction` that the uprights form the necessary arch for the cultivator, and by extending upwardly in the manner described and shownpermit theplow-sec tions to be more readily operated, as the line ofpull upon the plo wt-sectionsis brought substantially in the same plane in which the horizontal shifting lever operates.` t i It is frequently desired `to raise the plows partially out of the ground to lessen the depth of the cut or entirely from the ground during the operation of the cultivator; and to attain this object we employ the usual gear-segment and operating-lever for raising the plow-sections, the segment being'attached, as usual, to the stationary frame. The means we employ y for locking the segment and lever, however, we believe to be entirely new with `us, and the particular construction of saidlocking mechanism will now be described. The reference-letter O designates the usual gear-segments,- which are ixedly secured to the inclined bars c of the stationary frame. Pivoted to the same bars in proximity to the Segments are the operating-levers P for the sections, each of which levers is connected by a spring a; to the forward crossbar Z7 or any other suitable part of the frame and by a-link M to the plow-section. In construction each lever is preferably bifurcated, as shown in Fig. 5, comprising an outer membery and an inner member z, which embrace at their lower ends the bar to which the lever is attached and are pivotally secured thereto by a pivotpin a';

In the lever members justreferred to, above the segment, are formed slots through which extends a latch b', said latch being pivotally connected to the membery by means of split pins c', engaging the latch upon opposite sides of the outer member. The latch just described is held normally in engagement with the teeth of the segment by means of a spring d and is withdrawn from and vlocked out of said engagement by means of our improved locking mechanism, consisting, essentially, of a connecting-rode' and a lockinglever Q.

More `particularly the construction of the locking device is as follows: The lever Q is pivoted, as shown in Figs. 5 and 6, to the inner member e' of the operating-'lever P and is quired distance and holds the plow-sections IOO in their raised positionsby allowing the latch l to again engage with, the segment.

yWhenit is desired to allow the`plow-sections to rest upon the ground and to swing Vfreely,the,driver moves forwardly the locking-lever@ until it passesover the dead-center, when furtherforward movement of the lever is checked by the stop g striking against the member y of the.` lever P. The latch is IIO `then locked in the desirediposijtion out of engagement lwith the segment;

`Vhat we claim` as ourl invention is- `l. In a cultivator, the combination withthe stationary fram e, the pivotedaxles, arms proj ecting forwardly `from the axlesand a crossbar connecting the arms, a movable frame ex tending rearward `from said axlesuand controlling the movement of the latter,a seat upon said movable frame, the plow-sections y l pivoted to the stationary frame, `and counections between each plow-.section and the cross-bar connectingthe fcrwardlyprojectingarms. n N -V 2.
