T 0 all who mitmag concern.

Be it known that I, Ilf iLLURICIO L. Novo, citizen of the United States, residing at Guadalupe, in the county of Santa Barbara and State of California, have invented certain new and useful Improvements in Cultivators, of which the following is a specilication.

This invention relates to cultivators and one object thereof is to provide a structure whereby the direction of travel of the cultivator may be reversed without turning the complete implement. i

A further'object of the invention is to provide simple and efficient means whereby the gang of cultivating-blades may be set at any desired angle.

And a further object of the invention is to provide a cultivator of a strong and duable construction whereby the life of the implement will be prolonged and its efficiency increased.

The invention is illustrated inthe accompanying drawings, wherein:'

Figure 1 is a plan View of one en1bodiment of my invention,

Figure 2 is a central longitudinal section of the same,

Figure 3 is a transverse section on the line 33 of Fio'ure 1.

In carrying out my invention I employ a main frame consisting of angle bars 1 curved regularly from end to end so as to define semi-circular arcs. These frame members are disposed in the same horizontal plane with their ends spaced apart as shown at 2, and are connected at their 3 which are spaced inwardly from the vertical webs of the angle bars so that the spaces 2 will be left open to admit a locking pin hereinafter described. Spaced inwardly from theconnecting bars or membore 3 are intermediate braces a which may conveniently be flat bars disposed on arcs of the frame and having their ends rigidly secured to the horizontal webs of the frame bars 1 as will be readily understood. The frame bars are further connected upon their transverse radii by a beam 5 which may conveniently be a flat metallic bar having its extremities turned downwardly as shown at 6 to be rigidly secured to'the horizontal webs of the frame bars and support the intermediate portion of the beam above said webs. The beam 5 is offset vertically at its center, as shown at 7, and upon the coupling 15 may said offset portion a tongue 8 is pivotally secured a pivot bolt 9. As shown most clearly in Figures '1 and 2, the tongue extends unequal distances to the opposite sides of the pivot and upon the shorter arm thereoi oi secure a seat standard 10 carrying a seat 11. The longer arm of the tongue proect over and beyond the frame bars 1 and s outer extremity is provided with a i at it retaining plate or keeper 12 fromthe inner edge of which a fork or bracket 13 extends downwardly and rearwardly to engage under the adjacent frame bar 1, as shown most clearly in Figure 2. The tongue is thus prevented from riding up from the frame in an obvious manner. A clevis 14- is secured to the outer extremity of the tongue and this clevis may be of any preferred construction and any desired form of draft I be attached to the clevis and ad usted vertically thereon. In rear of the clevis, a longitudinal slot 16 is provided in the tongue and a locking pin or lever 17 is pivotally mounted upon the upper side of the tongue and has its lower end extended throu h the said slot and adapted to engage in either space 2 of the frame,

by its engagement with the sides of said spaces, prevent relative movement .of the tongue and the frame. The tongue may conveniently be a channel bar, as illustrated, and the pivot of the locking lever or pin may be mounted in the vertical webs or ribs of the said channel bar. In rear of the flocking pin or lever, a bracket or abutment 18 is secured uponthe tongue and a link 19 is extended through the said bracket or abutment and has its front end pivoted to tie upper extremity of the locking pin and at its r ar end is pivoted to a hand lever 20 which is mounted upon the tongue in advance of the seat 11 where it may be conveniently reached by the driver. A spring- 21 is coiled around the link 19 between the abutment 1S and the locking pin and is norm ally extended so as to hold the locking pin in. engagement with the space 2 between the opposed ends of the frame bars 1. A foot rest is provided upon the tongue adjacent the hand lever and the drivers seat and it may be secured to the tongue by one of the bolts which secure the base portion of the bracket 18 thereto.

.To the connecting bars 3 and 1, 1 secure the upper ends of standards 23 in the lower. ends of which is jour'naled a shaft 24 carrying discs, cutters or cultivator blades 25. In the illustrated embodiment of the invention, I have "shown flat discs which are adapted to cut into the surface of vthe soil sufficiently to hold the cultivator to a rectilinear path. It is obvious, however,

beam-5 by a pivot bolt 28 inserted through thesaid block 27 and the said beam. At their ends and at their centers, the angle. bars 26 are connected bythe heads 29 of standards 30;, the said. heads beingirigidly secured to the horizontal webs of the angle bars, and a cultivator shaft 31 being rotatably mounted in the lower ends of the standards; The usual concave rolling cul- "tivator'discs are fitted upon the shaft and spacing sleeves are mounted upon the shaft bB'tWQGIl the said discs so as to main :tainthe discs in fixed spaced relation. Ihe beams 26, ad acent their ends more remote from the pivot 28, restslidably upon a supporting arm or bar 34 which issecured to and extends betweenthe intermediate connecting portions 4 and defines an arc having the pivot 28 as its center. The cultivat'or beam is thus pivotally supported against, dropping and maybe set at any desired angle to the line of draft. In order that thegang of cultivator discs may be 'iheld' inthe'position in which it'is set, I

provide'thelugs 35 upon the standard 30 at that end of the gang remote from the pivot and to the said lugs I secure adjust inglchaiiis 36. Upon the connecting members or bars 4 I provide loops 37 having a keyhole slot formation. andthe free portions of the said chains 36 extend through the said loops; If a'linkof a chain 36 be engag'edin the reduced portion of the loop '37,

the ends of the connected links will extend across said reduced portionof the loop and thereby prevent movement of the chain tl'irough the same so that the chains will be held taut and the gang of cultivator discs held in the position in which it may be set.

To shift the gang, the adjusting chain 36 is released froin the reduced portion of the keyhole slot in the loop or keeper 37 and may then be easily drawn through the larger portion of said loop as will bereadily understood.

When the-cultivator has been drawn to I the end of a row or the side of a field, the driver swings the hand lever 20 rearwardly,

thereby piv'otally actuating the locking pin or lever 17 against the tension of the spring 21 and withdrawing the lower end of said the main frame.

pin or lever from the'notch or space 2 in The team or the tractor may then be driven around the cultivator frame, causing the tongue to swing about its pivot 9 and assume a relatively reversed position, as indicated by the dottedlines in i igure 2. The lever 20 may, of course, be released as soon as the locking pin has cleared the notch or recess 2 in which it was engaged and it will then ride around the outer side of the adjacent frame bar until it reaches the diametrically opposite space or notch 2'into whichit will at once be proiecte'd' by the expansion of thespring 21 ,in-

an obvious manner. It will thus be seen that the cultivator may be qiiickly brought into position to make a return trip and the gang of cultivator blades or discs will antomatically swing about its pivotal support when the return trip is. started. It will be understood that, except when the gang of discs 32is disposed in alinement with the beam 5, one of the chains 36 will be slack and the draft upon the gang will bring the advance chain into a taut condition so that the discs will be set in the desired operat-.

ing position. My improved cultivator may be produced at a low cost and its use will effect a pronounced saving of time inv reversing the travel of the implement and adjusting the cultivator blades or discs to the working position.

Having thus described the invention,

what is claimed as new is 1. In a cultivator, the combination ofa circular main frame provided with notches in its outer edge at diametrically opposite points, a tongue pivotally mounted uponthe frame at the center thereof and extending over the side of the same, a locking pin mounted for vertical rocking movement upon the tongue and adapted at its lower end to engage either of said openings in the main frame, and means upon the tongue acting on the upperend of said locking pin to set the same. I

2. In a cultivator, the combination of a circular main frame provided with openings in its edge at diametrically oppositepoints, a tongue pivotally mounted upon the main frame at the center thereof, a locking pin carried by said tongue and adapted to engage either of'said openings in the mainframe, abracket niounted upon the tongue at the inner side of said locking pin, a hand lever mounted upon the tongue at the inner side of said bracket, a link connecting the hand lever and the locking pin and extending through said bracket, and a spring coiled around said link between the bracket and the locking pin.

3. In a cultivator, the combination of a circular main frame, a tongue pivotally mounted upon the frame at the center thereof and projecting over the side of the frame,

means upon the tongue to engage the frame and hold the tongue in an operative position, and a keeper carried by the outer end of the tongue and engaging under the side of the main frame.

4. In a cultivator, the combination of a main frame, a gang of cultivator members pivotally supported eccentrically upon the main frame, and adjustable connections between the said gang of cultivator members and the main frame to hold the said gang in a set angular position.

5. In a cultivator, the combination of a main frame, a gang of cultivating instrumentalities pivotally connected at one end with the main frame eccentric thereto, an arcuate supporting bar upon the main frame upon Which the free end of the gang of cultivating instrumentalities is slidably supported, and adjustable connections between the latter end of the gang of cultivating instrumentalities and the main frame whereby to hold said gang in a set angular position.

6. In a cultivator, the combination of a main frame, a beam pivoted adjacent one end upon the main frame eccentric thereto and having its opposite end slidably supported by the main frame, a gang of cultivating members carried by said beam, slotted keepers upon the main frame at the opposite sides of the beam, said slotted keepers having reduced portions, and chains connected with the beam at the opposite sides of the same and at the free end thereof and adapted to engage the said slotted keepers.

In testimony whereof I affix my signature.
