To all wtonif 'it may concern,.-

Be it known that I, J AMES ARMsTEoNG, J r. of Elmira, in the-y. county of Stark and-Stai e of Illinois, have invented a new and Improved (ultivator, and I do hereby declare that the following is a full, clear, and exact description thereof, reference .being had to the aecompa# nying drawings, making a part of this specification,- in which- Figure 1, Sheet 1 is a plan view of niyimproved cultivator. Fig. 2, Sheet 1, is a longitudinal section, taken in a vertical: plane through the cultivator. Fig. 3, Sheet 2, is a rear `end elevation ofthe machine. Fig. 4, Sheet 2, is a perspective view, showing the mode of attachingonc ofthe treadles te ene of .the shovel-standards.` Fig. 5, Sheetf2,is atop View, showing theinode of attaching and adjusting one ofthe swinging shovel-standards. Fig. 6,. Sheet 2, is a perspective view of one of the shovels and its attaching-iron.

;Siniilar letters of reference indicate eor' spondingvparts in thseveral figures.

This invention relates to certain novel improvemcnts on two-wheeled cultivators,wh ich are more particularly designed for cultivating corn and iinishing the rows.' by once passing over them. ant to ride upona seat. which is located `in rear ofthe axle of two transporting-wheels, and in rear of the shovels, which seat is ap plied .npon'an articulating frame that extends1 both forward and in rear ofthe axle of said. l wheels; and ser vesy as a means by which to support shovel-carrying. standards arranged in rear ofsaid axle, substantially as will be-hereinafter explained, whereby a person riding upon lthe machine can always have the shovels in sight to inspect thework, and eau alsoemploy a leverage together with his own weight to ad,` vantage, for raising the shovels free lfrom the ground,aswi1l be hereinafter explained; also,

to -.enable theattendant, while riding upon a rear extension of va frame,whieh can articulate4 about theaxispf the transporting-wheels, tol

eonvenitiy Qontrol-the lateral movements of 'those shovels which are-nearest th'eplants by means `of his feet, forv the purpose of guiding- Xtheseshov'els alongirregular rows of plants, aswill beherenatter explained; also, to provide for pivotingthoseshovelhtandards which arenearest the'. plants to g nart of the frame o f My obj eet is to enable the attendy the cultivator, in such manner that these shovels can be adjusted .and lset so that they will either throw the earth about the roots of the plants, or throw it freni the plants, as may be requirechas will be hereinafter set forth; also,

to provide for adjusting the frame of the maf chine higher or lower upon its axle, and supporting such frame at different heights thereon for the purpose ofregnlating the depths which is is desired the shovels should run in the ground when in working position, as will be hereinafter explained.

To enable others skilled in the art to nnderstand my invention, I will describe.the best means known to me of carrying it into effect.v

In 4the accompanying drawings, A repre -Sent l two transporting-wheels, .which 'turn loosely upon theends of axle '13.'

C C are two longitudinal beams, which are secured rigidly to the axle 13 at an equal distance-on each side of its center, and extend Yfor-'ward and in rear of the axle any required distance.

D D are `two beams, which are somewhat -longerthan the beams C C, and which' are arrangedroutside of the latter, and pivoted to them at a. aby means of horizontal transverse pins, as shown-in Fig. 1. The .forward ends offthe two longitudinal beams D D are .connected together by transverse brace Z1, and the rear endsof these beams D D a1'e" con`11ecte`d togetherl'by'. a transverse board,'D, which is adapted to serve as a support for the driver or `attendant, to allow him to ride upon said beams .-D'D in rear of the axle B. At an intermediate point between the two transverse pieces b and Dj', and slightly in rear oilthe axle Bris a transverse brace, C', to which, and also to the frdnt brace, b, ,the draft-'pole is rigidly se' cured, as shown inA Figs. 1 and 2. The two longitudinal beams D Dand their cross-braces b C constitute.. the supporting-frame for the shovel-standards, which are four in number-e to wil', two outer standardsfFF, which are rigidly secured tothe rear ends of said beams. Tand two inner standards, G G, which are connected v by` pivot-joints to the 1 intermediate eross.-v bar, 'CL-as will be hereinafter explained. v l Thalongitudinal drafbpole E rests-upon a. stepped block, c, v hen the' shovels are in work- Y ing position, as shown-inthe;v rawingsjlh" 1, 2, and 3,' which lf lock clis secured upontug throughthe segments dd.

axle B in any suitable manner which' will ad init of anyone of the stepped surfaces being adjusted beneath the dra1tpole, so that the shovel-carrying frame may be' sustained atany 'desired height above the axleby its draft-pole resting upon one or the other elevationsjof the stepped block. By means of this adjustable block c the frame of the machine can be set so that the plows or shovels may be made to runf deeper or-shallowen in the'ground, as may be required. l i On the upper ends of the shovelstandards G' G perforated segments d d are secured,

which are formed on the rear parts .of caps' that have ears formed on them to receive and securein place said standards. vThese caps are pivoted ati 'i to longitudinal rods c e, the for- .ward ends of which-'are pivotedfto bearings ff on the cross-bar C', as shown in Figs. 1, 2, and.

1- 5. f These rods e e allow the lower ends of the two standards G G, which are connectedfby a cross-bar, g, tovibrate laterally, andthe@ vertical or nearly-vertical joints at allow said standards to be turned either tothe right orf to the left, as occasion may require; An ontward direction or an inward directionmaybe' givento the shovels on the standardsG'Gby; adjusting them about the pivots it', andthey maybe iixed in either of such positionsby the: pins-h h, which pass through' the endsI of tl'1 e"\ rods e and through the perforationsmade lThe standards G G, which carry the shovels intended to work nearest theplantaare` connected totreadles H H by means of rods j j',- curved` levers -I I, and connectingfrods k k, so

that by depressing either one of the treadles '-Y the lower ends of the standards G Gr` will be movedy inan exactly opposite direction. The i levers Il are pivoted to' the front side ofr the crossbar C', and curve over the longitudinal` beams of the main supporting-frame, asshown; vin Figs. -3 and 4. The two treadles H H- 'are` pivoted` to hangers beneath the front crossbrace, b, and these treadles extendback lieneath the axle Ba sufficient distance inrear 'of the same to be convenient for the attendant: to operatethem with hisiv feet while sittingupe.

on the seat D.

The rear ends of thelongitudinal beams G C- are carried out in rear of the axleB'a suitable distance, and areprovided on theseends-with stirrnps m m, 'upon which the attendant places' fxis feet when' he desires to elevate the shovel- .;arrying frame and thus lift the shovelsirom the'gronnd'.` 1 f thestandards carries a shovel,

Each4 one o s, which is bolted to a casting, f., that hastwo wings formed on it, which wings einbraceja standard near itslower end, and receive throughthem transversely a pivot, nl l`By thus connecting -tlie shovels to-` their standards, itVv will be seen that the shovels will remain stili' while'y the machine -isa'dvaneing; but when the Inachine isbacked or turned, lthese shovels will swing forward on their pivots n, instead of bef inglbent or broken. Vhen the attendantderf mas sires to raise the shovels freefrom the ground, hevremoves'his weight frolnthe shovel-carrying frame and applies it to the rear Aends of levers C C, to depress these ends, and as the front ends ofv these levers arel pivoted to the shovel-carrying fiame in front of the axle B, and these levers have their fulcrav uponthis axle, it is obvions-thatthe rear part of the said frame, with its shovels, will be lifted in proportion to thedistance the rear ends of the levers C are depressed. Under this' arrangement the rear end of the draft-pole Ewill be raised at thesame timethe shovels are raised.

It will be seen from the above description that I employ two pair of longitudinal beams, arranged across'the axle 'of two transportingwheels, and extending both forward and in real.l "of said axle; also, that the rear ends of one -pair of saidbeams-serve to snpportthe driver s seat in rear ol'v the axle and shovels, while the front ends off-thispair serve as a means for connecting-the lother-pairoi' beams by pivots to them infront ofthe axle; also, that one pairof-beams 1 a leverage, (the axle B being thefu1crnm',) to enable the driver to employ the weight-or power ofhis body toraise the shovels free fromthe' ground-.-
