being had to the accompanying drawings, and

to the letters and figures of reference marked thereon, which form a part of this specification.

My invention relates to a, series of improved devices in asulky-plow, which willbe hereinafter fully described, and set forth in the specification and claims.

Figure 1 is a side elevation, the right wheel being removed. Fig. 2 is aside elevation of.

the left side, the left wheel being removed. Fig. 3 is view partly in section of the apparatus for raising and lowering the land-wheel. Figs. 4. and 5 are sections of the same. Fig. Fig. 7 is a top View of the seat-arch. Fig. 8 is a perspective of the oscillator through which the plow-beam passes and receives oblique adjustment. Fig. 9 is a perspective of the hanger attached to the crank or bail and supporting the oscillator. Fig. 10 is a vertical section of the adj usting device for the land-wheel. Fig. 11 is a. vertical longitudinal section of the apparatus for raising and lowering the plow. Fig. 12 is a View of the same apparatus as Fig. 11,- but partly in section, and showing the attachment of the quadrant to its support. Fig. 13 is a perspective of the quadrant cast in a single piece with the pfgvot for the lifting-lever and Fig. 14 is an inside view of the quadrant attached ,to its support and with the lifting-lever attached.

Fig.15is alongitudinal section oftheoscillator. A A are the wheels, B the seat-arch, and G the crank or ball to which the plow-beam is v pivoted; D the plow-beam, E the mold-board,

and 2. The crank or bail G is disconnected from the axle, and has its bearings in the seatarch at O 1 Fig. 6, and is connected to the hand-lever N by means of the lifting-lever K, straps L, and bar M. When theplow is down to-its work the bail lies in a horizontal position, as seen in Fig. 2,in consequence of being pivoted above the beam D, instead of below, as usual. So it will be readily seen that when .the bail is raised but slightly above the horizontal by means of the hand-lever N and its connecting mechanism the draft at the end of the beam assists to raise the plow. -The plow-beam D passes through a wedge-shaped hole in the oscillator J, as seen in Fig. 15,

-(the oscillator is plainly shown in Fig. 8,) the front portion of the oscillator fitting the beam closely, and flaring rearwardly, where it is provided with the set-screws R R for oblique adjustment and to hold the beam when adjusted. The lower'end of the hanger I hasa pivotal socketed bearing, S, upon which the hole T in the oscillator J rests, and is held in place by means of a bolt, U, Figs. 1 and 2. end of the oscillator has the curved slot V, Fig.

8, which passes over the screw-bolt W, Fig. 9,;

and is held in place by nut Y, Fig. 2. The corrugations X X, Figs. .8 and 9, hold the oscillator firmly in place when adjusted.

The upper Thus it willbc seen that the oscillator, Fig. v

8, serves the double purpose of adjusting the plow both obliquely and laterally, the, ob-

lique adjustment of the plow being effected by; means of the set-screws R R at the rear part of the oscillator, and the lateral adjustment or swinging ot' the plow effected through the means of the slot V and the pivot S on the lower end of the hanger I, the corrugations X X on the oscillator and hanger holding all firmly when adjusted. In my construction there is no lateral adjustment at the clevis required, the whole being accomplished at the bail through the means of the wedge-shaped hole in the oscillator and the set-screws It It, ae seen in Fig.15. Neither do I require a jointed tongue to govern the land of the plow. The draft being in a straight line, the

wheels do'not incline to drag sidewise, as whenthe adjustment of the land is accomplished through the means of a jointed or adjustable tongue. r 1

through clamp X.

The seat-arch is provided with two socketed bearings, Z Z, for the tongue-timbers A A. When the sulky is to be used with two draftanimals the tongue is bolted beneath the middletongue-timber, A,and when three animals are to be used the tongue is bolted to the other timber, A. In Fig. 1, A is seen, and in Fig. 2, A. By reference to Fig. 6 it will be seen that A may be placed in the center socket, Z, and A placed in the outer or left-hand socket, Z.

The quadrant A Fig. 13, is cast in a single piece, ready for use, and provided, in addition to the usual notches in the periphery, with a seriesofholes, P,in conjunction with the notches R. A pin, S, is provided and held in place by means of a nut, T, as seen in Fig.1. When the plow is to be locked in the ground the pawl Y falls into the notches in the periphery of the quadrant, and requires attention to see that the pawl is placed in the same notch each time after raising the plow.

By means of the holes P and pin S the operator, after having determined the depth at which it is intended to plow, may place the pin S in a hole accordingly, and throw the lever down until it strikes the pin and lets go the latch without any care as to which notch it will fall into.

The quadrant is provided with a lug or hearing, U, and cleats V V, as seen in Fig. 13. The cleats V V embrace the tongue timber or bar A, and the lug U forms the pivot for the liftingdever, the whole being held firmly in place by means of. a single bolt-,W. The clamp X connects the lovers M N by means of the boltBpassing through thewhole. Thisclamp X carries the pawl Y, which falls into the notches in the quadrant, as seen in Figs. 12 and 14. The pawl is connected to the latch D by means of the rod 0. The spring on the latch throws the pawl down into the notches in the periphery of the quadrant.

By reference to Fig. 11 it willbe seen that the bolt B passes through the levers M Nand The lip A of clamp X falls down on the inside'of the quadrant and prevents thelever from slipping 011' of the stud U of the quadrant. The pawl Y slides in a. recess in clamp X. Thus it will be seen that a single bolt, 15, holds levers M N, clamp X, and through said clamp the pawl Y, and also holds the lever on the stud U by means of the lip A falling down on the inside of the quadrant. A single bolt, W, holds the quadrant firmly in place, as seen in Figs. 11 and 12, by means of the cleats V V elaspin g the timber A.' Thus the two bolts B and W hold in place the entire lifting mechanism.

The clamps E are attached to the bail on either side of the hanger I, for the purpose of parallel lateral adjustment of the plow to adapt it to two or three draft-animals or other circumstances.

The foot-rest L extends back beneath the center tongue-bearing, and the bolts M pass upward through the rearend. of the foot-rest to hold it in place, and through the slots 1? of the bearings Z, through the ton gue-timber A, and up through the seat-spring N which spring supports the seat 0 The seat-arch is cast in a. single piece with the various bearings, cast as integral parts thereof, as shown in Figs. 6 and 7, with the vertical part R upon which the land-wheel mechanism slides up and down to adjust the sulky to the depth of furrow required, and with the slots 1? for the bolts which hold the tongue-timbers. As the pattern parts in the middle, these slots 1? may be cast and avoid the necessity of drilling holes for the bolts. Thus the seat-arch is cast ready for use without anydrilling or fitting whatever. rugations to support the land-wheel in position when adjusted, are shown in Figs. 3-and 4.

The hollow bearings P and S for the bail and the lifting-lever for the land-wheel are shown in section at Fig. 10. The bearing 0, Fig. 6, is provided with a cap, T, as seen in. Fig. 2. The land-wheel A is placed upon the spindle U Figs. 3 and 5, the spindle being attached to the slide V, which slide moves up and down on the part R of the seat-arch. The set-screw W performs the double oftice of holding the spindle U in place and also the lifting-bar X which lifting-bar is connected to the crooked lever Y by means of a socketjoint, as best seen in the section, Fig. 10,whero it will be seen that there is no strain on the bolt, except to hold the parts together. The lever Y is pivoted on the hollow bearing S of the seat-arch, and held upon the hearing by means of the bolt B By means of the lever Y and the lifting-bar X the slide V carrying the spindle U is raised and lowered, and held in position by means of corrugations, as shown in Fig. 4, where the corrugations are held in contact by means of the cam-lever 0 which cam operates upon the corrugated block D to press it in contact with the part B of the seatarch, as seen in Figs. 4 and 5. The part B of the seat-arch containing the corrugations is sloped or beveled, as seen in Fig. 5, and the corrugated block D is sloped to match, the sloping of these parts being for the purpose of clamping the slide V more rigidly to the seat-arch to prevent the land-wheel from wriggling. By this construction the land-wheel is held as firmly to the seat-arch as therfurrow-wheel.

When it is necessary to raise or lower the slide V and axle the cam-lever G is thrown up, and a lug, F attached to the cam, strikes a lag, E attached to the block D and withdraws the teeth of the block ll) from the teeth of the part B of the seat-arch, and allows the slide V to play freely up and down on the part B of the seat-arch, and when the slide V is adjusted the cam-lever O is pressed downward and the whole firmly clamped together, the whole mechanism being cast ready to go together without fitting.
