Application filed July 17. 1907. Serial No. 384.1941

of Illinois, have invented certain new and useful Improvements in Lister-Cultivators; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to 'which it appertains to make `and use the same. l p

The main objects of this invention'v are to improve the general construction and increase the eiliciency ofloperation of lister cultivators of the character set forth in my prior patent No. 7 81011 and pending app ication Serial No. 293544; Patent No. 868,107, dated October 15, 1907, and, 'more especially, to

enlarge the range oi' adjustment of the cultivator-rigs andtheir supporting and guiding wheels; to improve the construction Whereby the implement is mounted to permit raising the rigs by throwing back the wheels relative to the frame; `and to provide an implement of the character noted having, in addition toits other capacities and functions, the further capacity of enabling its course to be deflected Without disturbing the alinement of the Working parts to the corn row.

The foregoing results are accomplished by means substantially as represented in the accompanying drawings, which are to vbevtaken as a part of this specification; it being understood, however, that the details of con-v struction and arrangement of parts of the illustrated machine may be modified in various ways without departing from theprinciple ot' my invention; so that I do not desire to be limited to -the specific construction shown. i

The invention will first be described by reference to said drawings land then more par'- ticularly pointed out in the appended claims.

Figure I of said drawingsois atop plan View of a two-row im lement embodying' my invention,said imp ement comprising two dexibly-coiinecte'd cultivators or sets of supportin -wheels'I and cultivator-rigs respectively y 'shown in Fig, 1*,

a( aptedigforfworking one row. Fig gis an enlargedplan View' of one of the cultivators or one set of supporting- Wheels and culti'vatorrigs together with the draft-tongue and frame-Work therefor. Fig. 3 is a side :view of the cultivator shown in ltion is notfrestricted to Fig. 2, with dotted lines indicating an elevated position of the cultivator-rigs. F ig. 4 is a rear perspective view of one of the cultivators arranged for the iirst operation of cultivating young corn. Fig. 5k is a rear perspective view of one of the cultivatorsarranged for the second cultivation of the corn after it has reached a larger and more hearty growth. Fig. 6 is a similar view of one of the cultivators arranged i'orY the third operation of the corn after the plantshave attained a considerable height, this being usually the last cultivation after which the plants are left to mature and yield their produce.

In Fig. 1, which represents a two-row implement of a general character similar to that disclosed in my former application Serial No. 293544, two wheel-supportedk7 cultivators or opposite sets of supportingwheels and associated pairs of cultivatorrigs, each arranged for working on opposite sides of a row of corn, are shown flexiblyconnected and laterally movable onV a transverse seat-frame; so that, in operation, the opposite pairs of rigs are 'tree to move in and out to conform to variations in the width or distance between the rows or furrows. The cross-bars B and C oi' the seat-frame are shown joined by a medial seat-bar D and the two tongues or draft-poles A, to which the opposite pairs ol supporting-wheels and cultivaifor rigs are respectively attached, areconnected to said cross-bars B and C by any suitable means allewing said tongues to move laterally on the seat-frame, for which purpose the front cross-bar B is shown passed loosely through or slidably fitted in the eyes of eye-bolts b on the tongues, while the rear cross-bar C is slidablyitted in the apertured l ends of brackets or straps c affixed to the tongues. The eye-bolts 'b are preferably swiveled br pivotally secured in the tongues A, and the strapse are also pivotally attached y thereto. The tonvues A are also shown pivotally connectedy by links E to the op osite arms of a lever F which is medially l-. crumed or pivotally secured to the central seat-bar D; whereby the tongues and sets f of cultivator-rig's attached thereto areeaused to move laterally in and out at opposite sides of the machine in unison, and at e ual distances from the seat-bar, as explains in My present invenmy former application.

any particular construction of seat-frame and flexible connection between the cultivators, the arrangement shown being illustrated only by way of example. f

Each set or pair of cultivator-rigs, together with the corresponding pair of supporting and guidin wheels on which the implement is mounte and frame-work whereby said cultivator-rigs and wheels are attached to the respective tongue, may for the purposes of this specification be considered as a one-row cultivator embodying my improvements, and a description of one of such cultivators will suffice.

As shown, the tongue A is rigidly attached by an end bracket or strap a and side braces a1 to a rear transverse frame-bar or member A1, which in the present case is shown comprising two I-beams bolted together. These parts constitute the rigid draft-frame for one act of cultivating devices, which frame is mounted on pivotal wheels H having an extensible connection with a lever on the frame for castering said wheels in unison.

lThe said pivotal wheels, together with trailing cultivator-rigs carried by the frame,v are adjustable laterally for varying the space between the wheels and rigs and the said wheels with the rig-frames are also swung from the main frame in such manner that the rigs can be lifted or swung upward by moving back the wheels relative to the frame, while, the implement is normally held in balance by the pull of the team, which holds the wheels forward and draws the cultivatingpdevices down into the soil.

The mode of attachment of the wheels and cultivator-rigs to the frame, whereby the foregoing results are obtained, -is as follows: The frame-member A1 is mounted on a divided arch G, swung therefrom and adapted to be widened or narrowed, thus constituting a laterally extensible supporting frame, the half-members of which carry the respective wheels H and 4rig-frames which work on opposite sides of the row. For this purpose,.

said arch com rises, preferably, two reversely arrange :l-shaped half-members, and the upper arms of said half-members are journaled or rotatably secured in horizontal sleeve-bearin s g, which latter are adjustably-secured by clamps g1 to the rear framemember A1. The lower arms of the said halfmembers are equipped with fixed pipesleeves J, of square or angular exterior c'onfiguration. Brace rods g2 are shown joining the outer ends of the upper and lower arms of the half-members of the arch. On said pipesleeves J are adjustably-secured, by means of clamps 'i and 7c, the bearing-boxes l1 of the pivotal wheel-carrying standards or caster spindles l, and the front ends of the trailing r1g-fra1nes K. By means of the clamps 'i and lc, the wheel-standards and rig-frames can be independently adjusted laterally on theI avaler square sleeves J, as may be necessary, while the division of the arch G, to which the wheels and rigs are attached, permits adjustment of the Wheels and rigs together for widening or narrowing the distance between them, in accordance with adjustments needed for cultivation at various stages of growth of the plants.

The rig-frames K and cultivator-gangs carried thereby are, by way Aof example, shown substantially as disclosed in my former application; said rig-frames comprising straps or bars between the rear ends of which are bolted blocks L, having bolted or attached thereto the Shanks of rotary cultivator disks Q and oblique shovel-beams M and N; said shovel-beams M and N being arranged at opposite sides of the row, each carrying a front cultivator blade or shovel O, and rear cultivator. blade or shovel P, and the cultivator disks Q being respectively arranged between said blades O and P, and inclined corresponding to the Obliquity of the respective shovel-beams M and N. The two rigs or gangs of cultivating devices are interchangeable and adapted to be transposed from one to the other side of the row, which is most conveniently accomplished either by transposing to opposite sides the blocks L l with the parts attached thereto, or by transposing the whole rig-frames K with the parts attached thereto but may also be. accomplished by transposing the shovel beams M and N and Shanks of the disks In Fig. 4, which represents the cultivator arranged for the first cultivation of young corn when it is desired to destroy the weeds` which spring up in the furrow and on the sides of the ridges, the half-members of the arch G are shown brought together, and the solid faced disk-wheels H are set to travel in the bottoni of the furrow against the sides thereof and thus guide the travel of the ri s and blades which do the cultivating work. The disks Q are arranged to throw outward, and they scrape off the sides of the ridges to a slight depth, throwing the surface a little further away from the furrow'and destroying the weeds. The rig-beams M and N converge rearwardly, carrying the rear cultivater blades P in the furrow, so as to weed out foreign growths on opposite sides of the row, and carrying the front cultivator-blades O along the tops of the ridges, so as .to stir up this portion of the soil and destroy all growths thereon.

In Fig. 5, which represents the cultivator arranged for the second cultivation after the plants have attained a more advanced growth, the arch-members G andwheels H remain as before, so that the wheels still travel inside of the furrow-walls but the cultivator-rigs or gangs are trans 'osed and the front cultivator-blades O are eft off. The rear cultivator-blades P, which by transpo- 15 rig-frames, so as to run 45 Shown mounted on the clamp @79,187 sition of *he rigs are thrown further apart, between the lever lil and cranksarm ll in run on the tops of the ridges, while the disks are arranged to throw inward and slice oil' portions of the ridges and throw them in the furrow, leaving the furrow about half full,

more or less. l y `In Fig. o, which represents the cultivator arranged for the thir'd cultivation at a later stage of growth of the corn, after which the l plants are left to ripen, the rig-s retain the I same general position as lfor the second opcri ation, but are spread apart by widening` the l arch G or spacing the half-members thereof. ,i .The wheels l are also arranged outside of the far apart possi.- ble. In this operation, the disks Q, take the l remainder of the ridges and throw them to the corn, leaving the dirt .hilled u p for about i four or'iive inches against the corn, and the I' surface on the sides at practically its original. l level, this surface beingl stirred up hy the f rear cultivating blades. l The above explanation of the successive y cultivating operations is substantially as set forth in my aforesaid application, and is rel peated here for a clearer understanding of l the illustrated implement. l desire it to be i understood, however, that my present inven tion is not confined to any particular construction of cultivatorlrigs or gangs, since l other suitable types or species of rigs or gangs may be used if desired. 'lt should also be l understood that the foregoing explanation is made more especially with reference to the l particular utility for which the implement is i lnteniled, but without essential imitation l thereto, the implement being' adapted forA other cultivatingl purposes.

The pivot-standards or caster-spindles lf, 40 which carry the pivotal wheels H, are provided on their upper ends with crank-arins R, and said crankarms are connected by connecting rods R1 to a link S1, which latter is connected to tlrleshorter arm of a lever S, 'i1 at one endof the rear franie-har A1; said lever S being provided with the usual supplemental lever and l springactuated lock-bolt for engaging a l notch in a rack S2. The wheels ll Arun parl allel and normally are in alinenient with the I direction of travel of the team, in which position the Wheels are held hy engagement of the aforesaid lock-bolt with the rack S2. But on disengaging said lock-bolt from the rack, the lever S can be moved to turn the cranks R, through the connections S1 and R1, so as l to pivot or caster hoth wheels in unison, l thereby delecting the course of the imple l ment, hut'without affecting the alinenient of the cultivator-rigs to the row of corn. The t two connecting-rods R1' overlap and are joined by adjustable clamps r, to one of l which the link Sl ispivotally attached. By l loosening the clamps 1', the rods can be shifted so as to extend or shorten. the connection l cordance with the spacing between the halfinenihers ol' the arch (l, which carry the respective wheels li and cultivatorrigs.

For l'iolding the implement in balance hy the hitch. or pull of the team, and providing for raising the cultivating-ilcvices from the soil when desired, a construction suhstantlally similar to that of my aforesaid applicaH tion included in the present implement. As shown, a forked or bi-lnzuiohed'lever T, pivotallymwunted on the draftefraine, straddies the tongue A, and the lower ends of said Iii-branched lever helow the tongue are connerted hy a. curved link U to the whitiletree lV to which the horses are hitched. Said lower arms of the forked lever '.l are also connected hy draft-rods V to the lower parts of the arch-members G, said draft-rod? flieing shown hooked in apertured ears on the square sleeves fl. Supplemental draft rods u, adjustahly attached hy clamps lu1 to the draft-rods l, extend to the outer ends of the lower arms of the archsmemhers G, being shown hooked in apertured ears on the collars g, which latter coi'meeti-.idv hy the aforesaid brace-rods Qg'to the upper arms of said arch-members. The clamps i-nahle the draftfods u to he adjustahly connected. to the main drafurods V, in accordance with the widening or narrowine1 of the arch G. Thus, Yby means of the under hitch., thepull of the team holds the wheels and cultivatorrigs in proper relation to the frame, the nis pleinent being in balance, and the draft tends 100 to revolve the rigs and. wheels on the upper horizontal arms of the arch, and 'thereby pulls the rear cultivating hlades and rotary disks into the ground. The upper end of said forked lever '.l is connected hy a rod or 105 link X lto a lever Y, having' the usual supple* rnental lever and lock-bol t for engaging a seg'- mental vrack Z mounted on the tongue A.. By pulling hack on the lever Y, the forked le ver l is thrown forward, as indicated ll'ig. 11a 3 by dotted lines, therehy pushing' hack the wheels li and lifting' the rigs. llihen the le ver YY is thrown `forward, the pull of the team again pulls the wheels forward and draws the cultivator devices into the soil. The lever Y is shown i-mgag'ing in a yoke or stirrup ai on the link X.. Said yoke or stirrup a: can slip or slide on the rod X., and is pressed forward against any suitable stop rc on said rod hy means of a coiled spring e2, the latter being 120 interposed between the yoke a; and a collar or stop on the rear end of the rod X. When the operator is starting the machine, Rhe throws the lever Y forward and locks itin the notch of the rack Z at which the machine 125 is desired to work. ln this movement, theA shovels are lowered, and when they strike thei ground the operator continues to push vthe lever Y forward, thereby compressing .the spring` m2, until the lever Y is .held at .thede- 130 di o the team, and they continue to lower untilthe stop :ri strikes the yoke fr, when the desired depth is reached. The purpose of the springl :rz is to obviate thenecessity of the operator keeping his hand on the lever l' and pushing until the shovels are down.

'From the foregoing itwill be observed, ti t, in addition to capacity for adjustment to meet the requirements oi cultivation at various stages oi" growth, including the widening or narrowing of the arch which carries the supporting wheels and cultivating rigs and also independent adjustment of' said wheels and. rigs laterally on the arch, and in addition to the capability of the arch to swing on its upper bearings, allowing the wheels 'to move back and lift the rigs, and allowing the rigs 'to ce brought forward and the cultivating devices to be drawn into the soil by the pull ol the team, the pivotal whee s are adapted to be tmncd to `deilect the course ol' the implement, but without disturbing the .-.ilincinent oi the working parts te the row, and without aller-,ting the other capacit and functions of the machine.

ln a two row implement, reprr-isented in l? l, the levers S and Y oi both oultivatorsl extend inwardly within range of the drivers se t, so that the driver can operate any one or more of saidlevers at will;
