CULTIVATOR.

Application filed February 3, 1912, Serial No. 675,385. Renewed September 21, 1914. Serial No. 862,789.

which the supporting-wheels and shovel-- beams may be angled in unison with respect to the line of draft.

The cultivator of my present invention is of the general type disclosed in my companion application Ser. No. 654,401, filed Oct. 12, 1911, which'embodies a supportingwheel and shovel-beam mounted on a crankaxle at each side of the frame in such manner that each crank-axle might swing on a separate vertical aXis to angle its wheel and beam with respect to the line of draft, and a parallelogram frame connected with each crank-axle for raising and lowering the crank and its shovel-beam. The carryingwheels are connected through a seat support, for maintaining the wheels in parallelism, the seat-support being movable laterally to angle the wheels in unison.

One of the primary objects of this invention is to provide a cultivator of the foregoing type with means for automatically locking the shovel-beams in their raised position. Y

Another important object of my invention is to provide means, preferably foot-operated, for releasing the shovel-beams from their locked position, which means are operable also for guiding the cultivator by angling the wheels and beam with respect to the line of draft. My aim in regard to this feature is to provide commonly operated means for both moving the beams vertically and angling the wheels with respect to the line of draft. Such means are provided so that when a driver has finished cultivating a row and is about to commence another one (the beams having been locked elevated at the end of the row), he may release the beams and move them into lowered working position by mechanism which is also operable for guiding the cultivator by angling the wheels.

Another object is to provide foot-operated means for moving the beams vertically and angling the wheels and to so associate these foot-operated means with the foot-operated means for releasing the beams from Patented Oct. 17, 1916.,

their raised locked position that the opera- Y tion o f raising and lowering the beams and of guiding the cultivator will be easy to perform.

I' also aim to provide meansof a novel design for raising and lowering the cultivator-beams and for automatically locking them raised, whereby a very serviceable and eiiicient structure which may be manufactured at a low cost results. I also embody 1n this means a foot operated latchfor automatically engaging a beam-member when the beam has been moved to a raised position to lock the beam therein, whereby the latch may be manually operated to release the beam.

Another feature of my invention is the provision of a quadrilateral beam raising and lowering frame with sides of unequal lengths and arranged in such manner that the rear end of the beam carried by such frame may be raised higher than its forward end. l In the accompanying drawings Figurev 1 is a perspective view of a cultivator embodying my improvements, the near carrying wheel being removed, and the far beam being shown elevated. Fig. 2is a side elevation of Fig. 1. Fig. 3 is a perspective view of the foot lever means for raising a beam, the beam shown locked in its elevated position. Fig. 4 is a plan viewof the swinging seat support. Fig. 5 is a plan section of the support latch taken on the line ca -a of Fig. 2. V

The frame of the cultivator comprises the tongue 1 connected to the diverging bars 2 which are connected by a cross bar 3. The diverging bars are connected with the cross bars by brackets 4 which are part of the vertically disposed tubular journal sections 8. A vertical shaft 7` is journaled in each section 8 and carries at its lower end an aXle 5 upon which is mounted a carrying wheel 6. Adjacent the lower ends of shafts 7 are bracket portions 10 xedly attached-to said shafts, and to the bracket portions 10 are bolted rearwardly extending seat supportf ing bars 11.y A cross bar 12 supporting seat ject matter of a divisional application ofH this case and bearing Patent Number 1,064,267, dated June 10, 1913. It will be noted that while the cross bar l2 forms a seatA support which can be swung open to all-ow the driver to enter in front'ofthe seat, it also forms the connection betwren the" two shafts 7, and thus betwen the supporting wheels 6 whereby both wheels when angled to the line of draft through the pivoting of shaft 7 will angle simultaneously.

A toothed-segment 9 is boltedfto the upper end of each shaft 7 and a hand lever 19 pivote-d to each toothed-segment, is provided with the usual manually operable latch, vand has a forward extension 20, providing a bellcrank arm, which supports a roller 21.

To-.each of the toothed-segments 9' is piv oted a link 22 which rests upon a roller 21. rlhe inner end of each axle 5y is provided with a forwardly extending crank arm 23 shorter than the link 22' and having its end turned inwardly as indicated by 24; andfdisposed parallel with axles 5 and forming a Zshaped member. And bar 27 shorter in length than the distance between the pivot of axle 5 and link 22 is pivotally connected at its ends to each of the links 22 and axle crank sections 24;, this latter connection being by brackets 26 which are bolted to the bars 27 and have externally square sleeve extensions 25 loosely mounted on the sections 2st, there being fingers 2S bolted to the outer sides of bars 27 and overhanging the crank arms 23 to hold the bars and sleeves in position. llt will be noticed that the above structure forms a quadrilateralframe the opposed sides of which are unequal in length. This frame which is a beam supporting frame has the general character of a parallel movement structure, whereby the bar 27 will be bodily elevated; but by reason of the unequal lengths of the opposite sides of the frame, said bar 27 will be canted to an angled position to raise angularly a beam carried by said frame. A beam 29 or beam supporting frame is attached to the lower end of each bracket, 26, substantially at right angles to bar 27, and forms a support to which shovels 30' or various other earth agitating devices may be attached. Inset shovels 31 are supported through the sleeves 25. Draft means are attached to the forward end of the beams 29 and have connection with the tongue l.

` To each bracket 10 is pivoted a yoke '32 connected afoot-lever 38 by which means the yoke is rocked to raise the bar 27 and beam 29. A bell-crank lever having on one arm a foot-lever 35 andon its other arm a catch 3G, is pivoted to each yoke 32 and a ward on foot-lever 38', thereby rocking the yoke 32 and raising in a swinging parallel likevmovement Athe bar 27, thereby raising the beam 29. Since the bar 27 forms a side of a quadrilateral and is shorter than its opposite side, (the shaft 7) it will not assumey a vertical position throughout its raising, but will. be canted to an angle as is shown in the raised position of Fig. l, thus raising the beam 29 in an angled position with the rear end thereof higher from the ground than the front end. inclination of the beaml is desirablev when traveling with the beam elevated, for the reason that rocking of the beam results by the rising and falling movement of the tongue 1 caused by the horses and by passi-ng over uneven ground, and therefore this higher elevated position of the rear shovels gives them a wider range of rise and fall without contacting with the ground. The forward shovels are not required to be subject to such diversity of movement. Then the beam has reached its said elevated position the catch 36 will engage an under face of sleeve 25 as shown in Fig. 3, and thus hold the beam locked in its elevated. position. To release the catch and drop the beam the dri-ver presses downward on the foot-lever 35, thus disengaging catch 36 against the action of spring 37 and allowing the beam to fall. W`henit is desired to raise the beam by the second method, by hand, the lever 19 is moved backward and downward thereby raising the bar 27 through the arm 20 roller 2l, and the catch 36. locking the beam when in its raised position, as above described.

It will be noticed that at any time the lcver 19 can be operated to regulate the depth to which-L the shovels shall .vork, through means of the arm 20 and roller 21, and that by setting the lever in a position for the desired working depth, the foot-lever 38 can be operated entirely to raise the beam. then the beam is loweredL the link 22 will be limited in its downward movement by the set roller 2l, whereby the shovels will be limited in their working depth.

When cultivating it is desirable that lhs` driver have his` hands free from/operating any ofthe `shovel-f.mechanfsnrin order that he may properly handle the reins to guide the team. It is necessary to raise and lower the shovels because of obstructions and at the end of a row when turning around; also it is necessary to guide or steer the cultiva- Y pressing down on each catch release foot-l lever 35 he may lower the beams, the beams dropping to their predetermined depth limited by the hand levers 19. Now it becomes immediately necessary that the cul-V tivator be properly guided, and with his feet still upon the catch release levers 35 he may control positively, by forward pressure on these levers, the angling of the carrying wheels in whatsoever direction he desires, the shovels being not affected'in their working position other than being angled laterally in unison. Y

From the foregoing it will be manifest that I have provided novel means for controlling the raising and lowering of the shovel-beams and for guiding the cultivator by angling the wheels with respect to the line of draft, and that the same arev arranged for most convenient operation by the'driver, who may adjust or shift the beams easily and with little eifort.

It is believed that my invention and its mode of operation will be fully understood from the foregoing and it will be obvious that the invention is not circumscribed by the details disclosed for purposes of illustration, and that the invention is capable of adaption to various changes in construction without departing from the spirit of the invention as described in the appended claims.
