SID E-HILL SULKY-PLOWQ SPECIFICATION forming part of Letters Patent No. 372,884, dated November 8, 1887.

Application filed October 14, 1886. Serial No. 316,221.

I To all whom it may concern:

Be it known that we, HARRY WIARD and WILLIAM R. BULLOCK, of the city of Syracuse, county of Onondaga, State of New York, have invented certain new and useful Improvements in Sulky-PloWs, of which the following description and drawings is a specification.

Our invention consists of certain devices in the construction and arrangement of two plows in a sulky-frame, some of which may be applied to other purposes. These devices are herein shown in a'rightand left hand plow, as is more fully set forth in the following description and drawings, in which latter Figure 1 is 'a rear elevation with one of the plows in the ground. Fig. 2 is a side eleva-' tion of the same. Fig. 3 is a plan of Figs. 1 and 2; Figs. 4 and '5, the couplings for connecting the plow-beam to the crank-axle; Fig.

6, an end view of the coupling; Figs. 7, 8, and

11, an enlarged view of the pole-connections,

plan,and elevation; Figs.9 and 10, the seat-connection with the pole for automatically shifting the seat sidewise.

In the several figures like parts are designated by the same letters of reference.

The frame a, uniting the several parts of the plow, consists of a casting, as seen in the drawings, composed of a top bar, from which three projections extend downwardone at the center and one at each end at the sides. This frame is supported on the. wheels with which it is connected by means of two independent bent or sunkcranks, forming the axles, one for each wheel. Each of these axles is'bent into the following form: a straight arm, '0, is

pivoted to the lower end of the center proj ection at b, and extends radially therefrom backward in the line of draft, where it is bent at right angles to form the wrist w of the sunk crank, which at its opposite end is bent to form an arm, at, at right angles to the wrist,

but inclined downward from the plane of arm 0, as clearlyseen in Figs. 2 to 11. The lower end of this arm a: is bent outward to form the spindle y, on which the wheel turns. An arm, 0, is affixed to the arm :10, near its junction with the wrist w, that extends up to the bearing at the lower end of the outer projection of the .50 frame a, where it is pivoted at b on a line with b at the center. This forms the outer bearing 'of the frame on the wheel.

No model.)

of the sunk crank and the support of the end Thus constructed, when the wrist w is down, as shown in Figs.

2 to 11, the wheel spindle is brought nearly in line under the pivot 12 on the frame, and when the wrist w is turned back and upward the wheelspindle follows it. (See dotted line, Fig. 11.) By means of this construction the sulky is leveled on uneven ground, as hereinafter described. The plow-beams are attached one to each of the wrists w of the sunk cranks by the following coupling: a stop-piece, 01, formed of two parts, (see Figs. 4, 5, 6,) is firmly clamped to the wrist w of each axle (see Fig. l) at the proper point toadjust the plow-beam laterally. This stop (2 has a groove atone end, into which a sleeve, e, made in two parts, clutches, so that when bolted together over the wrist w and stop d it turns freely without lateral motion. To the upper section of the sleeve 6 there is a projection, c, to which the plow-beam is bolted, so that the plow-beam will be raised with the crank-wrist, by which the plow is raised from the furrow, and. the wheel will be leveled up to the opposite one.

On each end of the frame a there is affixed a segmental rack, R, and a lever, L, is pivoted at 0 so as to move in front of said rack. This lever L is affixed at its lower end to the spindle y of the axle. There are two short handles or levers, n n, pivoted to lever L near its upper end. (See Fig. 2.) These levers are connected with a sliding pawl, u, that moves up and down in a recess in lever L by means of a pin projecting from the face of the pawl that entersa slot in the handle it. There is aspring on the pawl that forces it upward when free, and causes a lug projecting from the inner face of the pawl through lever L to catch into the teeth formed on the under side of the segment-rack, so as to hold lever L in proper position. By grasping the handle a at the same time that it takes hold of the lever L the pawl u is pushed down and the lever L is freed from the rack B, so as to be moved forward or back, as desired.

When the plow is to be raised from the ground, the handle a is brought into action, which carries the pawl a farther down than the handle it and clutches its lower end with the ratchet-wheel y, affixed to the wheel of the sulky, by which the hand is assisted in lifting the plow from the furrow. XVhen the plow is properly raised, by throwing the lever L forward a lug on the sliding pawl strikes a pro jection on the upper side of the segment R, which throws up the pawl and releases it from the ratchet-wheel y. 'When the parts are in this position, by forcing the lever L farther forward the wheel is still further raised, so that the sulky can be leveled on uneven ground and the relative height of the wheels can be adjusted with the greatest accuracy and held by the notches on the segment below, as above named, all of which is effected by a single lever for each plow and axle. This action is facilitated by the weight of the driver upon the seat, aflixed as hereinafter described.

To the front face of the framea there is a projection, a, to which a reach, r. is affixed, extending beyond the ends of the plow beams. Near the front end of reach 0' a cross-bar, t, is affixed to it, (see Figs. 1 to 3,) from the outer ends of which braces t extend back to the frame a, one on each side. On the front end of the reach 7* there is a shoe,f, in which a footleveizf, is pivoted, its outer arms being curved for a foot-rest on each side of the reach. From the front of this lever, at its pivoting-point, an arm projects (see dotted lines, Figs. 3 to 7) that fits into a recess on the under side of the pole 1), which is pivoted at its rear end to the projecting lug of the frame above named, and lies upon the reach, extending forward to hitch the team to. By this arrangement, when one arm of the foot-lever f is thrown forward, it moves the pole over to one side (see dotted lines, Fig. 7,) to work leverf automatically. Its ends are connected by rods f with arms on the crank-axles (see Fig. 11) that move with them. The seat 8 is supported by a spring. 8', bolted to the pole 1) at its forward end, and in rear of this pivot bolt there is a collar, 2, affixed to the reach below, inclosing the pole and spring above with sufficient breadth to allow the pole sufiicient side motion. The

spring .9, being pivoted to this collar 2, is turned to the side opposite that the pole moves to, with the seat attached thereto, to automati- (See firmly attached, and also to the reach. This I rod bears rollers on it, against which the front part of the plow-beam strikes, and are held from rising as the plows are lifted. (See Fig. 3.) The clevises on the front ends of the beams are connected by a draft-bar, it, formed of a single rod bent at each end into an eye that hooks into the clevis. When either of the plows is in the ground, its clevis is thrown forward and the bar It is inclined forward at that end, which causes the hook by which the team is hitched to the bar to slide to that end in proper position to draw the working-plow. In reversing the plows the hook slides to the opposite end. When both plows are raised, all the parts are in place for centering the sulky and beam.

Having thus described our invention, we claim 1. In a double sulky-plow, the independent combined plow and spindle-cranks composed of the arms 2), w, and c, wrist w, and spindle y, substantially as described.

2. In combination with the frame a, the two sunk crankaxlcs, as described, having bear ings in the frame placed in line with each other at the points b b, as and for the purposes specified.

3. The combination of the reach 7', pole p, and leverf with the crank-axles by means of connecting-rods f for shifting the pole automatically, as described.

4. .The combination of the reach 7' and pole p with the leverf for varying the angle of the pole, as described.

5. The combination of the seat-spring s with the pole p, reach r, and collar z for automatically adjusting the seat, constructed and operated substantially in the manner and for the purposes specified.
