Application filed February 27, 1812. Serial No. 680,223. 7

To all whom it may concern Be it known that I, IIAYES GADmE, a citizen of the United States, residing at Wellington, in the county of Sumner and State of Kansas, have invented a new and useful axes to guide the machine,- the steering 'mechanism being .operable by the person riding on the cultivator and being unaffected by the actuation of the balancing mechanism. I

Another object is to provide improved means whereby the cultivator ,sliovels can be shifted vertically within the machine, said shovels being disposed n groups or gangs and each gangflpeing shiftable either with or independently, of the next adjoiin ing 11.

A further object is to provide means whereby the cultivator blades or shovels can be shifted transversely of the machine so as to adjust them relative to the rows.

Another object is to provide a lock iiicluding means whereby the cult vator blades are automatically unlocked prior to their transverse adjustment, the means for shifting or transversely adjusting the blades be ing employed for actuating the lock to hold said blades in any position to which they may be adjusted. I

With the foregoing and other ob ects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, can be madewithin the scope of What is claimed, withoutdeparting from the spirit of the invention.

In the accompanying drawings the preferred form ofthe invention has been shown. In said drawings :-Figu're l is a plan view of the machine. Fig. 2 is a rcar elevation thereof. Fig. 3 is a side elevation, one of the supporting wheels being removed Specification of Letters Patent,

Fig. 6 is a section on line A-B Fig. 5. Fig. 7 is an enlarged transverse section through one of the guide members and the stem carryinglblock therein. Fig. S is: a perspective view of one of the gang heads. Fig. 9 is a perspective view of one of the cultivator beams. Fig. '10 is a View partly in side elevation and partly in section of one of the gang operating levers. Fig. 11 is a side elevation thereof, the segment of the Fig. 12 is a sec- Referring to the figures by characters of reference 1 and 2 designate front-and rear parallel frame members each having depending parallcl arms 3 at its ends. The side of the machine are connected by a guide member 4 parallel with the plane occupied by the frame members 1 and 2. Another guide member 5 is secured to the upper end portions of the arms 3 at each side of the machine and is parallel with the guide member 4 thereunder. As shown in the drawings guide member and it is to be understood that the member 4 is to be similarly slotted. I The two guide members 4 and-5 at each side of the machine are of like construction with the exception that the upper guide member 5 is provided,

at each end, with an enlargement .6 fitting snugly against the angle portions of the frame members 1 and 2, where the arms 3 extend downwardly through the enlarge being attached to the frame members 1 and 2 by U-holts 7 or the like straddling the frame members.

Thus it will be seen that the guide members 5 arefixedly connected to the frame members l and 2 as well as to the arms 8 and,

therefore, rotation of the frame members-is prevented and the arms 3 Any suitable means may be employed for securing the lower guide members at to the arms 3. Draft beams 8 are mounted on the frame members 1 and 2' and carry a cross beam 9' to which is connected draft mecha-' 5 is slotted longitudinally" are maintained at all times in fixed relation to each other.

elevation nisin indicated generally at 10. The beams S constitute additional means for holding the frame members 1 and 2 in proper relation to each other. An additional beam 18 5 is fixedly ecured to the members 1 and 2 at points equidistant from the beams 8 and extends rearwardly from the frame member 2 so as to form an efiicient support for the seat 19. A tie strip 20 connects the front 10 end of this beam 18 to the middle portion of the transverse draft beam 9. Brackets 21 are mounted on the beam 18 and a longitudinally extending shaft 22 is journaled in these brackets, said shaft being bent to form an elongated crank 23. Oppositely extending arms 24: are formed on or secured to shaft 22 close to one end of the crank 23 and each arm is connected, by means of a downwardly extending link 25, to a foot lever 26 which extends rearwardly to a point where it can be conveniently reached and actuated by a person occupying the seat 19. Thus it will be seen that upon the depression of one of the levers 26, one of the 25 arms 24 will be pulled downwardly and the shaft 22 rotated so as to swing crank 23 toward one side 01. the machine whereas, when the-other lever 26 is depressed, crank '23 will be swung toward the other side of the machine.

Mounted for sliding movement in the slot in each of the guide members 5 is a block 27 having ears 28 at the sides thereof and spaced. therefrom to receive the side portions of the guide member 5, as illustrated in Fig. 7. Anti-friction wheels 29 are journaled in the spaces between the block 27 and its ears 28 and constitute supports for the member 5. Another block 30 similar in all respects to the block 27 is mounted within each of the lower slotted members i and extending through these upper and lower blocks 27 and 30 are stems 31 provided, at their lower ends, with spindles 32 arranged at right angles thereto. These stems 31 are prevent-' ed from moving domiwardly within the blocks 27 and 30 by collars secured to the stems and bearing downwardly on the lower blocks 30. Upward l'l'lOVQIl'lQllil of the stems 5G 31 within the blocks is prevented by collars 34: bearing upwardly against the blocks, as shown in 1' 2. Supporting wheels are journaled on the spindles 32. is to be understood that the stems 31 are adapted to rotate'within the blocks 27 and 30. Arms 36 are fixedly connected to the upper ends of the stems these arms being parallel at all times and said arms are pivotally connected to a cross rod 37 which is parallel with the members 1 and 2 and extends above the crank 23.

whirl'r the crank 23 extends. Ti 7 t n it A hanger 38 extends down-' wardly from the middle portion of the rod.

be seen that when crank 23 is swung toward one side, hanger 3S and rod 3? will be shifted therewith, thereby causing the arms 36 to swing laterally and to rotate the stems 31. The two supporting wheels 35 will thus be turned so as to steer the machine in the desired direction.

The balancing mechanism constituting a part of this invention includes a rock shalt 10 journaled on the beams 8 close to the transverse draft beam 9 and this rock shaft is provided, at its ends, with (lOWTlWilldlY extending arms 1-1. Each of these arms has rearwardly diverging links 42 and 4:3 pivotally' connected to it, the upper link being pivotally connected. to the upper block 27 at one side of the machine, while the other link &3, is pivotally connected to the lower block 80. An arm 44 extends upwardly from the shaft 40 adjacent the center thereof and is connected, as by means of a rod 41-5, to a lever 46 fulcrumcd on the beam 18 where it can be easily reached by the occupant of the seat 19. This lever is provided with a toothed segment 17 adapted to be engaged by a pawl carried by the lever and whereby the lever can be locked in any position to which it may be adjusted. The said pawl been indicated generally at -18 in Fig. From the foregoing it will be seen that when lever i6 is shifted in one direction, shaft 4-0 will be rotated so as to cause arms 41 to pull forwardly on the links .2 and .13. As these links are connected to the blocks 27 and 30 carried by the wheel supportml stems 31, it will be seen that this action of the shaft 40 will cause the said shaft 40, and the structure made up OIl the frame men:- how 1 and 2, the beams 8 and 18. and the parts mounted thereon, to move rem-\varrlly, thereby shifting the center of gravity. When the movement of lever 4-6 is reversed, the operation will be reversed so lhut the center of gravity will be shifted forwardly relative to the supporting wheels 35. Mounted on the frame members 1 and at opposite sides of the central beam 18 are carriages d9. Each of these.carriagnis consists of parallel side members 50 connected by cross strips 51 and 52. Grooved Sll[')])011- ing wheels 53 are journaled in the end portions of the side strips 50 and bear downwardly on the frame members 1, and 2. Guide rods 5 1 extend transversely of the machine above and parallel with the frame members 1 and 2 and are supported at their ends by brackets 55. These rods engage the upper portions of the rollers 53 so as to prevent said rollers and the carriages from becoming displaced relative to the frame members 1 and 2.

A rack bar 56 cxlmirled from the rear end of each beam 9 to the rear end of the radium-sol; guide in- .--v- 5, this; rack bar being parallel with the rear frame member 2 and being extended under the rear portion of the adjacent frame 49.

Mounted on the rear end portion of one of the side members of each carriage 49 s an inverted U-shaped guide 57 in which 1s formed a slot 58. A locking pin 59 is mounted to slide within this slot 58 and its lower end is held normally in engagement with the rack bar 56, by means of a spring 60 which is coiled about the pin 59 and bears at one end against the guide 57 and at its other end against a pin 61 or the like extending from the pin. y

A yoke 62 is pivotally mounted at its center upon the upper portion of the pin 59 and extends downwardly so as to straddle the guide 57 said yoke having outstanding feet 63 which are slidably mounted within slotted guides 64 upstanding from the side strips 50 of the carriage. A rod 65 is pivotally connected to the yoke 62 at a point above the pin 59 and is also pivotally connected'to an arm 66 extending radially from the rear end of a rock shaft 67 journaled on one side of the beam 18. A handle 68 extends rearwardly from the arm 66 to a point where it can be conveniently grasped by the occupant of the seat 19. Another arm 69 ex-- tends radially from the forward end of the shaft 67 and is connected, as by means of a link 70, to abracket 71 secured on the front end of the side strips 50 of the carriage.

' It will be apparent, by referring particularly to Figs. 5 and 6, that spring 60 holds the spring 59 normally in engagement with the rack 56 and, when the pin is thus disposed, the yoke 62 is located in a substantially upright position. When shaft'67 is rotated in one direction by means of handle 68, either pulls or pushes through link 65, upon the upperend portion of yoke 62. The yoke is thus caused to tilt upon one of its legs 63 while the other leg is elevated within one of the guides 64. The yoke will thus pull on the pin 59 and lift its lower end out of engagement with the rack 56. This operation takes place during the.first portion of the movement of shaft 67. During further move; ment of said shaft the foot at the elevated side of the yoke 62 comes into contact with i the upper wall of the slot in guide 64 and is thus held against further movement in an upward direction. Consequently the yoke will be shifted laterallyby the link and will cause the carriage 49 to travel along the frame members land 2, the rollers 53 serving to reduce friction to the minimum. As soon as the carriage has been shifted transversely of the machine in this manner. until it has reached a predetermined position, handle 68'can be released whereupon spring 60 will return all of the parts to their initial positions, pin 59 moving into engagement with the rack 56 and thus locking the carriage against further movement. By connecting shaft 67'at its two ends to the carriage 49 at the front and rear ends of the carriage, it will be seen that said carriage will be held parallel with the beams 8 while being shifted. The position of the pin 59 and the parts adjacent thereto when shifted out of normal position, has been indicated by dotted lines in Fig. 5.

Extendingg" rearwardly from the transyerse draft beam .9 are brackets-7 2 supportmg a cross bar 73 which is preferably bolted or otherwise secured to the beams 8, as indicated at 74. Mounted on this bar in front of each carriage 49 is a pair of heads 75 each of which includes spaced ears 76 mounted for rotation on the bar 73. Two pairs of eyes 77 are formed on the heads 75, one

eye of each pair being disposed above the other eye and spaced therefrom. A collar 78 is mounted on bar 73 between the ears 76 and is adapted to be held against movement on the bar 73 by means of a set screw 79 or the like. Each pair of eyes 77 has a stem 80 mounted for rotation therein and .said stem is held against longitudinal move ment relative to the eyes, by means of a collar 81 which is secured to the stem by a set screw 82 or the like. at the upper end of a hanger 83 and the lower end of the hanger is provided with an upstanding stem 84. This upstanding stem extends through spaced ears 85-connected to the frontend of a cultivator beam 86. Said ears are engaged by the stems S4: of both hangers 83 connected to the heads 75 in front of the cultivator beam, as will be apparent by referring to Fig. 1, and the ears 85 are held against movement along the stems 84 by collars 87 which are interposed between the ears and are fastened to the stems by set screws 88 or the like. As shown in Fig. l the distance between the stems 84 is the same as the distance between the stems 80 and the hangers 83 are therefore parallel and form, with the heads 75 and the ears 85, a parallelogram which permits the ears 85 to shift laterally relative to heads 7 5 but causes said earsto remain always substantially parallel with the bar 73. The cultivator beam 86 is preferably formed of a length of metal having its rear end portion offset laterally so as to be engaged by the standard 89 of the rear cultivator blade 90 of the gang connected to the beam 86. Another cultivator standard 91 is-connected to the beam 86 in front of but to one side of the path of the blade 90. A metal strip 92 is secured to the rear end of the strip 86 andiextends alongside of the rear portion of said strip 86 and is then ofiset, at 93, where it is engaged by another standard 9% Stem 80, is formed nected, as by means of a rod 104, to a spring acenoae of a cultivator blade. Thus it will be seen that three standards are connected to the beam, said standards being out of alinement. It is to be understood of course that any desired number of standards may be connected to the beam and these standards can be disposed in any relation desired.

A guide ear 95 is extended laterally from the strip 86 and is slidably mounted on a' guide rod 96 suspended from one of the side strips 50 of the carriage 4:9 above the beam. The cross strip 51 on each carriage has two alining shafts .97 journaled thereon, each shaft being provided at its outer end with a radial arm 98 connected, by means of a link 99, to one of the beams 80 under the carriage. A forked lever 100 is loosely mounted on the two shafts 97 close to the adjoining ends thereof and straddles a toothed segment 101 which is fixedly mounted on the carriage 19. A gear 102 is journaled within the forked lever 100 and meshes with the segment 101, this gear being normally engaged by a toothed slide or pawl 103 mounted in the lever and conpressed lever 105. Pawl 103 serves to hold gear 102 against rotation and as this gear is constantly in meshwith segment 101, it will be apparent that lever 100 is normally held against movement about the shafts 97. A toothed segment 106 is secured to each side of lever 100 and is concentric with the shafts 97. Levers 107 are fixedlyconnected to the respective shafts 97 and close to the lever 100 and each of these levers 107 carries a-spring pressed pawl 108 normally engaging the adjacent segment 100. Thus it will be seen that levers 107, pawls 108 and segments 100 serve to normally lock the lever 100 to the two shafts 07. ll' ith. the parts thus connected it will be seen that, by shifting lever105 so as to raise the slidev .13, gear 102 will be released and lover 100 can then be swung about its fulcrum so as to cause the two levers-107, which are locked thereto, to rotate the shafts 97 simultaneously. The arms 98 extending from these shafts will, therefore, 'shift the links 90 so as to raise or lower the beams 86. Should it be desired to shift one of the beams below carriage 49 independently of the other beam, the lever 107 controllingsaid beam released from the segment 106 adjacent thereto and shifted independently of lever 100 hen the desired adjustment has been obtained said lever 107 can be locked to lever 100 by means of pawl 10% and ment 106.

It will be apparent that by using a machine such as herein.described, "H or ir supporting structure shifted 'Wardly or rearwardly relative to the axis rotation of thesuppcrting wheels and with tee or such movement will not interfere steering mechanism. Furthermore the two carriages can be shifted toward or from each other so as to move the cultivator blades toward or away from the rows or so as to adjust them to rows at different distances apart.
