Application filed February 24, 1920. Serial No. 360,599.

T 0 all whom it may concern lle it known that l, SHERMAN W. (lanY, a citizen of the United States. redding,T at Hamilton. in' the county of \Vcnt\\'ortl| and the Province of Ontario, Dominion ot' Canada. have invented certain 'new and useful Improi'enrents` in Balunced-xlc (lultirators. ol' which the following: is a full. clear. and exact specification.

This invention relates to tillage implements and is shown illustrated in connection with a type of straddle row cultivator shown in a copending application ot' (lhai'les Sharp #.3Il,l)-l5, filed October 4. lilla.

The ,general arrangement ot' the cultivatin-` to which the invention is yshown applied, comprises an arched wheel axle havin;r tor Wardly extending' arms swiveled thereto. the arms carrying* the. supportingl wheels near the swiveled connection with the axle and at their forward ends being' connected with a cross member to which the gang' frames are, attached. lln swiveling the wheels hy means of foot levers for the purpose ot r-teerirgr the deviceq the cross men her slides laterallyY with respect to a rigidi longue carryingr 'tramo upon which the cross member hears. and in this lateral motion ca 1ries with it the gang or tool carrying frames. `his results in a multiplied lateral motion o the tool carrying: trames' with reference' to the lateral motion of the cultivator as a Whole. occurs in a numher of differently designed cultiv vators now commonly in use.

A merit. of the above-mentioned type of cultivator is that hy rockinef the 'forwardlyT extending arms. cross connection and wheels as a unit around the Vertical portions of the arched axle. the vehicle is steered and the gangs are shifted toward the changed direction of travel Without changing their angie? lar settingV with respect to the normal line of draft and hilt a simple mechanism is re# quired.

The purpose of the present invention is to provide in the tvpe of machine described for properly maintaining` its halanee as the tool carrying frames are raised and lowered without necessitating material additions thereto or in any wav making; less satisfac- K torv the normal action of the machine. Sneh counterlialancine' is frequentlv accomplished hv shittingr the supporting Wheels lonfritndi nallv with respect to the tool gana frames, and results in certain disadvantages in con- L-shaned struction and action. In the present case eininterbalaneing is effected hy causing the tongue traine` seat and other parts supported therehy to more longitudinally as a unit with respect to the remainder of the machine, in correspondence with the vertical motion of thc gang frames. The tendency ot' the machine to tilt forwardly or rearwardly when the tool earning trames are raised and lowered is thus counteracted without a`ecting the action of the mechanism for steering' and lateral shiftingl ot' the gang.

Figure 1 is a plan View ot' the cultivator constructed in accordance with this invention:

Fig. L is a side elevation with one Wheel removed and `showing the tool frames in lowered position: and

Fig. 3 is another View like Fig. 2 hut with the gane* trames in raised position. and with the seat and tongue moved forwardly with respect to the remainder of the machine, as occurs upon the raising of the gang frames.

Cultivators are usually so arranged that while at work in cutting at some normal or predetermined depth. the reaction of the soil against the soil working tools will be suhstantially in the line of draft. and therefore such devices have the tendencyY to rotate around the axis of the simpel-ting wheels only when the tool carrying frames are raised or lowered with resnect to their normal working' position. This may result in an objectionable vertical motion of the tongue and annoyance to the draft animals, particularly when the tools are raised clear 'pt the around noon turningy at the end of a frow. Such action nreferftbly is collateracted in the nresent design hv cansinor a relative longitudinal motion between main supporting;r structure of the machine including' l the supportino wheels and fang frames, and the torene and seat support. during the raisine and loweringr of the gangs.

Pl-re' eultivator to which the present improvements are applied is shown in the drawings as havin,er snnportine wheels 1 journaled on lateral extensions 2 of upwardly and forwf-rfllv efztendin'r arms 3. Tlrese arms are bolted to hrackets 4 rwtfit'ihlv mounted en Yerticallv disposed partera of axles 6V rThe unner inwarfllv ex'- tendng parts 7 of the axles 6 are. as asu-vl in this type of machine, adjrrstably Secured within sleeves 8 by means of collars 9, which are partly encircled by sleeve.

The axles 6 are in gather, while the end portions of the this manner tied tosleeve S is tree to rotate a limited extent around the portions T of the axles. The arms 3 are tied together at their forward ends by a tool beam sup orting har l0 and a transverse I-beam 11. ach arm 3 has a vert-ical end portion 12 eatending into the socket of a bracket member 13, connecting the har 10 and beam 11. The tool frames 14 carry sleeves 15 at the"Y forward upper ends, encircling the bars 1U, and are by means of links 16 and lever 17 secured to the bar to move therewith during the swiveling motion of arms 3 and brackets 4 on the portions of 5 of axles 6. The arms 3, being parallel and Amovingr in an are around the parts 5, maintain the beam sup-A porting bar 10 parallel with sleeves 8 during the swiveling motion, and accordingly the tool frames 14 are maintained parallel with the normal line of draft when the vehicle is stee dto right and left far enough to cause t e soil working tools to avoid cutting irregular plants of a row. i

The mea-ns for etfectin;r the steering acv tion consists of foot levers 18 pivoted to seat trame 19 at QQ, and at their Jforward upper ends being attached to chains 21 which pass around lixed pulleys 2Q and then extend inwardly where they are attached to u casting 23 secured to the tool beam supporting bar 10. By this means. when the lower end of one of the foot levers 18 is pushed forwardly, lthe member 10 is shifted either to the right or to the let't, depending,r which foot lever is forced forwardly, thus Swingingr the arms 3, brackets Ll and wheels 1 around their pivotal support 5.

In order to adjust the gang trames 14 toward or away from each other so as to operate closer or farther away from a row ot plants between the gangs, the lever '17, to which the links 16 are attached at opposite ends may be rotated around its central pivot on castingr Rotation ot" lever 1T is effected hy an adjustable and lockable handle Q4.

tongllu` 25 from which depends the usual swingrletrcos4 und hangers 50. is pivoted hy bolt 2li to a draft frame QT. forming;r an cve tension ot' scat trame 19, and is vertically adjustable. for the usual purpose ottool trouw leveling;v at ditferent cutting depths` an iud the holt 2G by means of a lever 28 which is pivolcd to a bracket 29 secured to the rear end of tongue 25 und having: a quadrant 30. to which the lci'er 2S may be lockt-d in its tliilrieiit adjusted positions. The lover S is connected by a link 31 to a tic liar 3Q of trame QT.

The structure so tar mentioned in thereterence numbered part ot' the, description is substantially the same as that shown iu the before-mcntioned copending application. The present improvements relate. partn'ir larly to the unit formed by seat sulpport lil frame 27, tongue Q5. and the tool irar raising nuchanisin which is arranged iimpart longitudinal motion to saif unit dm ing the raising and lowering of the loo. frames.

The tollowiing description relates to the construction and. operation of the new fea tures:

The scat support d and the draft traum 27 are secured top-ether by volte-shaped cast ings 33 and comici-ting iinks spectively riveted to the frames l!) and il by the rivets 35, and ljt' and 2U. The cast ings are properl Y formed to provule bean mgsfor the pulleys 22 and form abutments for the I'beams which normally ride on rollers 3T journaled in the members The gangs are raised and the unit formed by seat frame 19, trame 27 and tongue 25 is shifted forwardly at the same time by means of a lever 38 pivoted to a quadrant 39, in turn attached to frame 27. Forward of its pivot 40 the lever 38. is pivotally connected with a link 41 which extends rearwardly and at its rear end is pivotally connected. with fan arm l2 rigid with sleeve S. The frame 27 at its rear end is also pivoted to arms 43 rigid with sleeve 8. Accordingly, when lever 38 is rocked upwardly from a position in which it is shown in Fig. 2 to that shown in Fig. 3, the sleeve Q is rotated to the right, causing forward movement of the frame, seat support 19 and tongue 25 attached thereto with res ect to the re -mainder of the machine. Jink 41 serves as a downwardly. moving fulcrum Jfor lever 38 so that a horiatmtal motion only will be imparted to the seat support and tongue The sleeve@ carries quadrants 44 whiii are normally engaged by locking dogs 5 on individual gang adjusting bell crank levers 46. These levers are accordingly caused to rock to the right upon the righthand rotation ot' sleeve 8. as above described. YThe lower ends of levers 46 are connected by lifting rods 47 with the gang frames 14.

lith the construction described, the unit Jformed by seat support 19, frame 27 and tongue 25is shttable forwardly and rearwardly by'means of lever 38 which simultaneously acts as a gang raising and lowering: lever. The weight of the operator and the tongue is thus shifted forwardly or rearf wardly with respect to the pivotal axis 2 according' to the extent the shovel gangs are raised or the depths to which the tools ltereon are caused to penetrate the soil. L

Lifting of the gang frames and forward motion ot the seat and tongue unit is assisted by a counterbalancing spring iS ez;-V

Iil which are ro y Larsson? ,tending between an erm 49 on sleeve 8 and the yoke-sl1a-ped bracket member 33.
