SULKY-CULTIVA'TOR.

SPECIFICATION forming part of Letters Patent No. 365,900, dated July 5, 188'7.

Application filed February 3, 1887. Serial No. 226,436. (No model.)

To all whom it may concer-rz:

Be it known that I, JOSEPH C. BIRD, a citizen of the United States, residing at Rising Sun, in the county of Cecil and State of Maryland, have invented a new and useful 1mprovement in Sulky-Cultivators, of which the following is a specification. i

My invention relates to an improvement in sulky-eultivators; and it consists in the peculiar construction and combination of devices, that will be more fully set forth hereinafter, and particularly pointed out in the claims. l

In the drawings, Figure lis aside elevation of a sulky-cultivator embodying my improve- Fig. 2 is a top plan View of the same. Fig. 3 is a front elevation. Fig. 4 isa rear elevation. Fig. 5 is a longitudinal sectional View. Fig. 6 is a detail horizontal sectional view, taken on the line x :r of Fig. 2.

A represents an arched axle, which is provided with the horizontal outwardly-extending spindles B, on which are journaled the supportingwheels C. The spindles are formed integrally with standards D, that are provided on their front Sides with grooves adapted to receive the lower ends of the armsof theaxle, and are bolted thereto. From the lower front sides of the standards D project horizontal ears E. Draw-bars F have their rear ends bolted to thesaid ears, and the front ends of the said draw-bars are provided with arms G, which are bent at right angles to the drawbars, and project inwardly therefrom toward each other. The said arms G are provided with longitudinal horizontal slots H. These draft-bars and their slotted arms are made of metal.

Ircpresents a vertical yoke, which is bent substantially in the form of au inverted letter ,U, and the lower ends of the vert-ical arms of the said yoke are provided with outwardly extending fcet, which are secured on the upper side of the slotted arms G by means of bolts K, that extend transversely through the said feet and through the said arms.

L representsinclined brace-rods,which have their rear ends secured to the vertical arm-s of the bent axle at a suitable height above the dral'tbars F, and the front ends of the said brace-rods are bolted to the outer ends of the draft-bars, and havetheir extreme front ends projecting from the front sides of the outer end s of the arms G to form ears M.

N represents the hounds, which have their rear ends attached to the arched axle by means of strapbolts O, and the said hounds are se cured near their front ends on the upper Side of the horizontal central portion of the yoke I. A cross-bar, P, connects the said hounds at a point above the yoke I, and bolts R pass vertically through the horizontal portion of the yoke, through the hounds, and through the cross-bars, so as to secure the saine rigidly together. The eXtreme front ends of the hounds are connected by means of plates S, which are bolted to their upper and lower sides, and between the said plates the rear end of the draft-pole Tis secured by means of a pivotal bolt, U. The said draft pole or tongue comprises two sections, tand t', which are secured together by a loose lap -joint at the point through which the pivotal bolt passes, and thereby the front and rear Sections of the tongueare adapted to play slightly independently of each other to prevent excessive rigidity of the tongue, and prevent the same from annoying the horses by moving their collars laterally on their necks when the'eultivator 0 is in motion. On the upper side of the rear section, t', is secured a metallic plate or arm, V, which extends rearwardly beyond the extreme rear end of the tongue, and to the said arm is pivoted a detent-link, NV, the lower edge of which is provided with a longitudinal series of rack-teeth adapted to engage ame tallic flange, W', that is secured to the upper Side of one of the hounds.

X represents a hand-lever, which has its front end pivoted to the crossbar P and extends rearwardly therefrom, the said lever being connected to the detentdink by a pivotal bolt, X', whereby the said link may be securedto the ange W at any desired point,

so as to shift the tongue from one side to the other and thereby regulate the side draft of the cultivator.

Y represents a doubletree, the central portion ofwhich is pivotally connected to the under side ofthe tongue by means of a bolt, Y. Link-bars Z depend from the ends of the doubletree and are pivotally connected thereto, and the lower ends of the said linkbars are connected to the brace-rods L by means of open links A, which are attached to the cars IOO 45 by means of pivotal bolts.

1o engage openings made inthe heads ot' the clevises, and the said hooks are secured upon pivotal bolts E', which extend transversely through the slotsin the arms G and have nuts on their rear threaded ends. rrlhe said pivotal bolts may be shifted laterally in the slotted arms and secured thereto at any desired adjustment by turning the nuts, and thereby the clevises, which are movable laterally with the said shifting bolts, and the hooks pivoted 2o thereto may be secured at any desired lateral adjustment to the slotted arms.

F' represents draw-heads, comprising plates f and f', which are pivotally connected together by means of bolts f2, w hich pass through 2 5 central openings made in the said plates and also extend through the vertical slots madein the clevises. These pivoted bolts have their front ends threaded and are provided with clamping-nuts, by means of which the drawheads maybe securedto the elevises at any desired vertical adjustment. -are" provided near their extremities with transverse slots f". Glampingboltsf3 extend through the ends of the plates f and also The plates f 3 5 through the slots f4, and are provided on their threaded ends with nuts. It will be observed that the plates f' are adapted to turn on the rear sides of the plates f, and that the said platesf' may be secured at any desired in 4o clination by means of the clamping-boltsf.

From the rear sides of the tnrningplatcs f' project ears f G' represents cultivator-beams, which have' their front ends secured between the earsf5 The said cultivater-beams have their rear ends curved downwardly.

g represents extended ainis,\vl1ich are bolted to opposite sides ofthe cultivator-beams, one

5o ofthe said arms beingin advance and the other being in rear of the downturned end of each cultivator-beam, andthe said arms g extend laterally from opposite sides of the cultivatorbeams and have their rear ends also curved downwardly.

H' represents standards, which are curved, as shown, Vand have their upper ends attached to the curved depending ends of the cultivator-beams and their arms, and to the lower 6o ends of thesaid curved standards are attached so as to cause the cultivatingshovels to run at equal depths in the ground. The clampingbolts]c3 serve to secure the turning-plates of the draw-heads at the requisite inclination, and thus keep the cultivator-beams inclined when once set. l

1' represents inwardly-extending horizontal arms, which have their outer ends bifureated and secured on the rear sides of the standards Dvby the same bolts which secure the said standards to the ,arms of the arched axle. To the inner ends ot' the said arms I' are swiveled keepers K.

L represents hand-levers, which are pivotally connected to the keepers K', and are provided at their front` ends with hooks M', connected to the cultivator-beams by means of links N'.- v

O' represents hooks which are attached to the said levers on the inner sides' thereof, and at a suitable distance in rear of the keepers K'. The function of the levers L is to raise and lower the rear ends ofthe cultivator-beams,

so that the cultivator-teeth may be raised 4entirely from the ground or. forced`downwardly therein to the required depth.

To each cultivator-beam, at a suitable distance from its rear end, is bolted a stirrup, P'. rlhe said stirrups are adapted to receive the feet of the driver, who sits upon a seat, R', that is supported upon the rear end of an arm, S. The said arm rests upon the central portion of the arched axle, and the front bifureated ends thereof Aare hooked to eyes T', with which the hounds are provided. By this means the seat maybe very readily detached from the sulky. The upper outer sides of the stirrups are curved forwardly, and are thereby arranged out of line with the remaining portions of the upper sides of the stirrups. NVhen the levers L have their rear ends depressed, the eultivators are raised until the stirrnps strike against the lower sides thereof. The said levers then have their rear'ends moved inwardly toward each other, which causes the rear ends of the cultivator-beams to be diverged, and lalso causes the depending hooks O' to engage the upper sides of the stirrups, so as to suspend the cultivatorbeams from the rear ends of the levers.

In order to facilitate the operation of raising the cultivators from the ground,'l` provide coiled retraetile springs U', the upper ends of which are connected to hooks V', with which the hounds are provided, and the lower ends of which springs are connected to keepers WV?, which are secured to the cultivator-beams near their front ends, These keepers arelongitudip nally adjustable 0n the cultivator-beams, and

are provided with set-screws W, by means of which they may be clamped to the cultivatorbeams at any desired adjustment. By shiftin g the keepers back or forth upon the cultivatorbeams the tension of the springs will be regulated at will.

Z1 represents chains which are connected to hooks A, that are attached to the rear ends of the draft-bars. The said chains are adapted to be attached t-o hooks V, with which the cultivatorbeams are provided. The inwardlyextending arms on the opposing sides of the cultivator-bcams are provided with hooks G2, and D2 represents a chain which is adapted to connect the said hooks. By means of the chains Z and l)Z the lateral play of the culti vator-beams may be limited or entirely prevented, as will be readily understood.

In order to prevent the cultivator teeth from throwing'dirt upon tender plants when the same are being cultivated, I provide the inner-extending arms of the cultivatorbeams with rearwardly-extending arms El, to which are attached fenders F2, that are adapted to run on opposite sides of the row of plants.

The operation of my invention will be very readily understood from the foregoing descrip tion and Vby reference to the accompanying drawings. The driver seated upon the seat It directs the team, and With one foot placed in cach stirrnp on the cultivator-beams he keeps the plow steadily at work and nieves them laterally when necessary in order to avoid obstructions. When the machine is in motion and not in operation, as when crossing a field, or when in transit on a road, the cultivator-beams are elevated and are attached to the hooks which depend from the lower sides of the levers L.

Having thus described my invention, Iv claim l. The combination of the cultivatori'rame having the horizontal transverse slotted arms G at its front end, the vertically-slotted clevises attached to theslotted arms G and adjustable laterally thereon, and the cultivatorbeams having their' front end pivotally con nected to the clevises and adjustable vertically thcreon, substantially as described.
