SPECIFICATION forming part of Letters Patent N o. 376,788, dated January 24, 188.

yApplication filed December 18, 1886. Serial No. 221,578. (No model.) Y v .To all whom it m Ltg/'concerne Be it known that I, WILLIAM STRAIT, a citizen of the United States, residing at Elmira, in the county of Chemung and State ofNew 5 York, have invented certain new and useful Improvements in Sulky-Plows; and I do declare the following to be a full, clear, andV ex actdeseription yof the invention, such as will enable others skilled in theart to which' it-appertains to make and use the same, reference being had tothe accompanying drawings, and to the letters and gures of reference marked thereon, which form a part of this specification. r

Figure 1 is a plan view of a sulky having my improvements applied thereto. Y Fig. 2 is a side elevation of the same. Fig. 3 is a rear elevation of the 4reversible plow shown in Fig. 1. Fig. et is a bottom view showing a plowpoint having my improvements. Fig. 5 is a bottom'view of a modified form of yplow-point, showing my device adapted to other kinds of plows. Fig. 6 is a detail, elevation of a segment-piece, hereinafter referred to.

ground, releasing the same, or regulating their depth of cut, all of which. is independent of the hand mechanism for'the same purpose.

The object of my invention is also to pro vide for the weight of the driver, assisting in balancing the plows; also, means for shifting n the reversible plow, jointing the-plow-point to 4o the plow, and other improved details, all of which will be first fully described, and the points of novelty then set forth in the claims.

The present invention 4is an improvement on that granted me December 15, 1885, No. 332,302, whereby the operator may bring a power-lift into operation for the purposeof raising the plows out of the ground, which lift is thrown into and` out'of engagement by the foot, leaving both hands of the driver free to manage the team.

rlwo or three horses aroused in drawing this sulky-plow. It will be seen from the draw- Fig. 7 is a detail view of the lever mechanism for ad.

ingsof the pole and neck-yoke that two horses travel as wide apart, or nearly so, as when three are used. In the latter case the pole is c A moved to the side poleseatand to the side horsesalone are used or whether a third or middle horse is employed. position kof the two outer horsesr takes ,place with respect to their position before the plow when the third horse is harnessed in. The only change isthe shifting of the draftfpole so .that it will be pivoted in the side hole, 14, of

the necklyoke instead ofthe centralhole', 13",v 7 as is the case when but two horses are .drawing the plow. This shifting of the pole is necessary in order 'to provide a space equidistant -between the two outer horses for the middle horse to travel in. By means of this arrangement .the off horse will travel in the-furf row `when a right-hand furrow is yturned and.V the nigh horse inthe furrow when a left-hand n furrowY is cut, no matter whether a middle or third horse is in the team or not. In order to 8 left-hand furrow the mold-board is `reversed and the beam shifted to the other side of the machine, and in such rposition that the nigh p horse travels in the adjacent furrow previously i cut. Toeffect this result properly where the 9 outerk horses of the team travel such a distance,` apart, whether a middle horse be used ornot, the wheels should be spread apart so that either may track the furrow behind the outer horsel in cuttingboth right and left hand roo furrows. f,

In thedrawingst represents the wheels of a sulky-plow. j v Y b are short axles secured inthe main axle or No change in the l 7o sie` C) effect this result when employing a single `re- Y versible plow, it is desirableto shift the plow.- beam laterally in cutting a right-hand furrow, so that the oft horse may travell in the ad#y jacent furrow previouslycut; and in cutting a 9o arch c of the sulky. The portion d of thearch forms a bearing provided with a rack-bar,l e, along its length.

f is a journal-box, which carries the plow and is adapted to be moved laterally along the bearing d from one side to the other for the purpose of giving lateral adjustment to the plow.

The side motion of the plow along the archbearing d may be affected in various ways. I have shown a method of providing a lateral adjustment by means of a pinion, g, located on the journal-box f. This pinion meshes with the rack-bar e, and is provided with a crank-arm, h, secured to the same shaft that pinion gis fastened to. The turning of the crank-arm h causes the plow attached to the j ournal-box f to travel the length of the archbearing d, according to the'degree and direction of rotation of the crank-arm.

:vis an arch or light frame attached to the axle, and to which is secured the spring which holds the rock-shaft m in its normal position and the pawls n out of engagement.

llare two projecting arms, formed on the axle at either side and adjacent to the wheels a. These arms project forwardly and upwardly from the axle, and their outer ends form boxes or bearings for the reception of a crank shaft, m, extending, preferably, across the frame of the machine. On this tilting crank-shaft (preferably at both ends) are dogs or pawls n, which under certain conditions are adapted to be thrown into engagement with toothed or ratchet wheels o, formed on the inner side of the hubs of both of the wheels a.

25 is Vthe forward frame of the machine. This frame, which carries the operating-levers,

the seat, and the draft-connections, is jointed weight of the forward frame, 25, added to that of the driver on the seat, has a constant tendency to oscillate the crank-axle and to lift and counterbalance the weight of the plow. At the side of the frame, near the forward end, is secured the segment-rack 19.

q is a hand-lever, provided with the usual spring-dog for engaging the segment-rack for the purpose of adjusting the depth of cut of the plow or for throwing the plow entirely out ofthe ground.

ris an arm formed on the lower end of lever q below the pivotal point thereof.

s is a link, pivoted at one end to the arm r of lever qand at the other to the arm s', which projects from the main axle of the sulky.

When the hand-lever q is thrown back and forth, it rocks the axle and raises and lowers the plow or plows, according to the movement of the lever q.

t is a foot-lever pivoted-to the segmentrack p. This lever has au' arc-shaped or circular surface corresponding to the shape of the segment-rack, and is arranged to lie under the path of the spring-dog on the hand-lever q. To the other end of the rocking foot lever t is pivoted a link, u, which in turn is pivoted to one end of the pawl n on the rock or crank shaft m, the purpose of all of which will be explained further on.

o is an arm formed on the rock-shaftm, and w is a foot-lever pivoted to the forward frame ofthe machine. These two arms and levers o and lw are pivoted and form a power-lever catch for the purpose of raising the plow or plows out of the ground.

The power lift is intended as a substitute for the hand-lever q, and either may be used at the pleasure of the operator.

When it is desired to raise the plows by the power-lift, the driver presses on thefoot-lever w, which, by means of the link at' and arm v, causes the rock-shaft m to rotate. The said rockfshaft being connected to the lever t by means of an arm, u, on the pawl or dog n and a link, u, the arc-shaped bearing of said lever is caused to move upwardly against the dog on the hand-lever q and raises said dog out of the notchesin the segment-rack. Justasthe dog on thelever g is thrown out of engagement the dogs or pawls n n on the ends of the rock-shaft m engage with the ratchets o on the wheels a. Now the forward motion of the sulky and the wheels raises the plows and carry the handlever g backward freely over the segment-rack p until the dog drops into a notch, 1, on the segmental piece p, thereby holding the plows up. At the same time that the dog on the hand-lever drops over the notch or lug y for the purpose of holding the plows out of the ground a trip-piece or projection, 1, which is bolted to the frame, strikes against the rockshaft m at the point 2 and throws the dogs u out of engagement withthe ratchet-wheels.

IOC

The trip 1 is adjustable in the line of its length by a slotted bolt connection or other known means. Y l

In the construction of my plow it will be seen that the weight of the driver assists in raising the plows. The frame of the sulky, to which the seat is attached, is in front of the pivotal vline of the axle and the plows are in the rear of the axle.

When the driver steps upon the frame or is in the seat, his weights helps to raise or balance the plows. In my Patents Nos. 332,301 and 332,302, for sulky-plows, the driver had Ato be in the seat to have his weight balance the plows, and in those cases when the hand-lever was used the weight was more or less taken from the seat. In my present invention the weight of the driver balances the plows, whether upon the seat or upon the frame.

The plow, which in the present instance I have shown attached to the sulky, is a single reversible-mold -board plow; in which said mold-board is swung from right to left,and vice versa, as it is desirable to reverse the furrow side of the plow in hillside plowing. For the purpose of etfecting the reversal of the molddriver onthe machine.

' in the drawings consist of two poleseats, in v s'lefley i j board I arrange a lever, r3, within reach ofthe This lever is pivoted at its lower en d to the brace 4, which connects the-mold-board to theplow-beam 5. The brace 4 is pivoted at its lower end to thelower part of the plow-standard 6. Lever 3 has a catch, 7, near the upper end of the lever, and the spring 8 opposite thereto, as shown in Fig. 2. The lever 3 passes through a slot, 9, in the plow standard or beam, which is flaredor eut away to' allowV of the levers having sufiicientylateral motion tov enable the plow to` reverse itself.

When the mold-board is over to the one side or the other in its proper place, the hook 7 on the lever 3 has passed up through the slot 9 and the spring/8 has thrown the catch 7 into engagementwith the upper side of the standard and locked the mold-board in position. When itis desired to reverse the mold-board,the lever '3 is pushed backwardly against vthe spring`8, when the catch 7 will fall through the slot 9 and the weight of the moldboard will swing itself upon the pivoted brace 4 downwardly and pass the center of the swinging motion. At that point'of the rotation a slight pull on the hand-lever 3 will swing the board into its place on the opposite side of the standard.

Figs. 4 and 5 show an improved means of securing the plow-pointto thesaddle or standard.

It is adapted for use for either hillside or reversible level-land plows. 10 is a projection or lug at the joint of the points, and l1 are recesses in the landside side-of the point of corresponding shape to a lug on the saddle or seatv lon the standard. -15 is a rib or ribs, Figs. 4

arid 5, formed on the landside side or sides of the plow-point, withinwhich the recesses 11 are` cut or formed. The advantages of this construction are that when the point is placed upon its seat it makes a trmerjoint with the mold-- a rm joint cannot be made between the plow! point .and the mold-board.

When, either by means `of the the handlever lift, the plow has been raised up out of the ground, and it is desired to lower the plow again without having to employ the hands or the hand-lever, it may be done by pressing the foot upon the rock-lever t, which lever presses upon the ydog of the hand-lever and raises it from the notch or lug y, when the weight of the plow will cause it to descend and the hand-lever q to swing forward to its normal position. Y

The pole t' may be'shifted or kthrown to one side in any known way to admitof the middle horse being harnessed in. The means vshown which the ypole is interchangeable.

The segmentbearing of this piece is iiush with or slightly above the teeth of segment p, so that the dog of lever 'q may slide freely along it. ,The stop or lu'g 17 isset adjustably, so as' to allow the plow to cut-apredetermined depth of furrow,

and at the same time to admit ofthe plow freely rising nutomaticall y when striking an obstruction.

18 is a lever-andrack mechanism'which j' admits ofthe plow being adjusted vertically when one wheel is down in the furrow or when the machine is working on hillside land. The plow-beam is fastened to the journal-box f by means of e'yebolts 19, s o that the -plowmay rock lat'erallyto provide for this movement. Y
