JOSEPH C. BIRD, OF RISING SUN, MARYLAND.

SPECIFICATION forming part of Reissued Letters Patent No. 10,959l dated September 18, 1888.

Original No. 365,900, dated July 5, 18E?. Application for reissue filed July 7, 188B. Serial No. 279,339.

To all whom it may concern.-

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 Improvement in Sulky-Cultivators, of which the following is a specification.

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

In the drawings, Figure 1 is a side elevation of a sulky-cultivator embodying my improvements, the near wheelbeing removed. Fig. 2 is a top plan view of the same. Fig. 3 is a front elevation. Fig. 4 is a rear elevation. Fig. 5 is a longitudinal sectional view. Fig. 6 is a detail horizontal sectional view.

.A represents an arched axle, which is provided with the horizontal outwardly-extending spindles B, on which are journaled the supporting-wheels C. The spindles are formed integrally with the standards D,that are provided on their front sides with grooves adapted to xceive the lower ends of the arms of the axle, 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 the said ears, and the front ends of the said drawbars are provided with arms G, which are bent at right angles to the drawhars, and project inwardly therefrom toward cach other. The said arms G are provided with longitudinal horizontal slots H. These draft-bars and their slotted arms are made of metal.

I represents a vertical yoke, which is bent q.vstantially in the form of an inverted letter md the lower ends of the vertical arms of said yoke are provided with outwardly-exiding feet, which are secured on the upper Je of the slotted arms G by means of bolts that extend transversely through the said feet and through the said arms.

L represents inclined brace-rods,which have their rear ends secured to the vertical arms of the bent axle at a suitable height above the .raft-bars F, and the front ends of the said 5o brace-rods are bolted to the outer ends of the projecting from the front sides of the outer ends 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 strap-bolts O, and the said hounds are secured 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 same 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 T is secured by means of a pivotal bolt, U. The said draft pole or tongue comprises two sections, tt, 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 tongue are adapted to play slightly independently of each other toprevent excessive rigidity of the tongue, and prevent the same from annoying the horses by moving vtheir collars lateral-ly on their necks when the cnltivator 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, IV, the lower edge ofwhich is provided with a longitudinal series of rack-teeth adapted to engage a metallic 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 detent link by a pivotal bolt, X', whereby the said link may be secured to the flange NV 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 dpubletree, the central portion of which is pivotally connected to the under side of the tongue by means of a bolt, Y. Link bars Z depend from lthe ends of the doubletree and are pivotally connected thereto, and the lower ends of the said link-bars are connected to the bracerods L by means of open lin'ks A', which are attached to the ears M and engage the lower ends of the link-bars. B' represents whiiiletrees, one of which is connected to each of the link-bars.

C' represents vertical elevises, which are p provided with vertical slots, and at the upper end of the said clevises are formed rearwardlyextending heads, which are adapted to enter 1o the horizontal slots in the arms G. D represents hooks which are adapted to engage openings made in the heads of the clevises, and the said hooks are secured upon pivotal bolts E', which extend transversely through x5 the slots in the arms G and have nuts on their rear threaded ends. The 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 elevises, 2o which are movable laterally with the said shifting bolts, and the hooks pivoted thereto may be secured at any desired lateral adj ustment to the slotted arms.

F represents draw-heads, comprising plates f and f', which are pivotally connected together by means of bolts f, which pass through central openings made in the said plates, and also extend through the vertical slots made in the clevises. These pivoted bolts have their 3o front ends threaded,and are provided with clamping-nuts, by means of which the drawheads may be secured to the clevises at any desired vertical adjustment. The plates f' are provided near their extremities with transverse slots j. Clamping bolts f extend through the ends of the plates f and also through the slots f and are provided on their threaded ends with nuts. It will be observed that the plates f are adapted to turn on the 4o rear sides of the plates f, and that the said plates f may be secured at any desired inclination by means of the clamping-boltsfa. From the rear sides of the turning plates f project ears f 5.

G' represents cultivator-beams, which have their front ends secured between the ears f5 by means of pivotal bolts. The said cultivator-beams have their` rear ends curved downwardly. y

g represents extended arms, which are bolted to opposite sides of the cultivator-beams, one of the said arms being in advance and the other being in rear of the downturned end of each cultivator-beam, and the 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, and have their upper ends attached 6o to the curved depending ends of the cultivatorbeams and their arms, and to the lower ends of the said curved standards are attached curved reversible cultivator teeth or shovels h. By reason of the turning-plates with which the a5 draw-heads are provided the culti vator-bearns may be inclined laterally to any desired angle, so as to cause the cultivating-shovels to run at equal depths in the ground. v The clampingbolts fSi serve to secure the turning-plates of Athe draw-heads at the requisite'inclination,

and thus keep the cultivator-beams inclined when once set.

I' represents inwardly-extending horizontal arms, which have their outer ends bifurcatef` and secured on the rear sides of the standan... D by the ysame bolts which secure the sa' standards to the arms of the arched axle. c the inner ends of the said arms I are swivele keepers K.

L represents hand-leveis, which are pivotally'connected to the keepers K', and. aro provided attheir front ends with hooks M', coiA nected to the cultivator-beams by means ot' links N.

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'. One function of the levers L' isto raise and lower the rear ends ofthe cultivator-beams, so that the cultivator-teeth may be raised entirely from the ground or forced downwardly` therein to the required depth. Another function of said levers is to shift the cultivator` beams laterally.

To each cultivator-beam, at a suitable distance from its rear end, is bolted a stirrup, P'. The said stirrups are adapted to receive the feet of the driver, who sits upon a seat, R', that is supported upon the rear end ot' an arm, S. The said arm rests upon the central portion of the arched axle, and the front bifurcated ends thereof are hooked to eyes T',with which the hounds are provided. By this means the seat may be very readily detached from the snlky. 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. When the levers I. have their rear ends depressed, the cultivatorsare raised until the stirrups strike against the lower sides thereof. The said levers then have their rear ends moved inwardly toward each other, which causes the rear ends ot' the cultivator-beams to be diverged, and also 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, I provide coiled retractile 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 W', which are secured to the cultivatorbeams near their front ends. These keepers are Iongitudinally adjustable on the cultivater-beams, and are provided with set-screws W3, by means of which they may be clamped to the cultivator-beams at any desired adjustment. By shifting the keepers back or forth upon the cultivator-beams the tension of the springs will be regulated at will.

Z represents chains which are connected to `The inwardly-extending arms on the opposite drawings. The driver, seated upon the seat 4in the simultaneous and cooperative use of vated and are attached to the hooks which de hooks A, that are attached to the rear ends l ofthe draft-bars. The said chains are adapted to be attached to hooks Vl, with which the cultivator-beams are provided.

ides of the cultivator-beams are provided i'lith hooks C, and Dl represents a chain which is adapted to connect the said hooks. 35: means of the chains Z' and D2 the lateral p'fay of the cultivator-beams may be limited or entirely prevented, as will be readily understood.

In order to prevent the cultivator-teeth from bhrowing dirt upon tender plants when the same are being cultivated, I provide the inner-extending arms of the cultivator-beams with rearwardlyextending arms El, to which are attached fenders F, 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 description and by reference to the accompanying R', directs the team, and with one foot placed in each stirrup on the cultivator-beams he keeps the plow steadily at work and moves them laterally when necessary in order to avoid obstructions. It will be noted upon inspection of the drawings that each hand and foot of the operator co-operates in controlling the movements of the cultivator-beams. The right handandthe right foot operate on the right cultivator-beam, While the left hand and the left foot operate 0n the left cultivatorbeam. It will be furtherV noted that while either hand pulls upon its lever the correspending foot pushes upon the stirrup, so that the operator is given a purchase, as it were,

hands and feet in controlling the movements of the plows. So, in like manner, the hands may push while the feet pull on the beams.- Vhen the machine is in motion and is not in operation, as when crossing a field or when in transit on a road, the cultivator-beams are elepend from the lower sides of the levers L.
