IMPROVEMENT IN SULKY-PLOWS.

Specification forming part of Letters Patent N0. 16] ,770, dated April 6, 1875; application filed January 22, 1875.

To all whom it may concern Be it known that I, JOHN FAY, of New Boston, in the county of Wayne and State of Michigan, have invented an Improved Sulky- Plow, of which the following is a specification The first part of my invention relates to a device for raising and lowering a plow suspended under a sulky-pole, both ends of the beam being moved at the same time.

The second part of my invention relates to the devices for securing the plow-beam in position and for guiding the same.

Figure l is a perspective View of my sulkyplow, looking at it from land. Fig. 2 is a partial elevation of the furrow side of the device, the furrow-wheel being removed. Fig. 3 is a cross-section at w 00, Fig. 1. Fig. at is a bottom perspective View of the rear end of the pole, showing the quadrant locking device.

In the drawing, A represents an arched and bent metallic axle, on one arm of which is mounted a traction-wheel, B, and on the other another and larger wheel, B, which runs in the bottom of a furrow. U is a pole or tongue, which is clamped to the top of the axle. a is a swivel-bolt passing down through the pole and axle. On its lower endis a swivel-bar, I), having down-turned ends, through each of which a setscrew, 0, is tapped. The swivel-bar is slotted at each side of the bolt-hole to receive the heads of two guide-bars, D, through the lower ends of which a screw-threaded eyebolt, d, passes, and on which jam-nuts e are placed to adjust the guide-bars to or from each other. The plowbeam passes between the guide-bars, which are adjusted at the top by the set-screws 0 0. The guide-bars are braced in a vertical position by a diagonal brace, E, extending from the eye of the bolt to the axle-arm of the land side, and by a vertical bar, E, bolted at the top to a clip on the axle, and at the lower end to an car on the head of the eyebolt. F is the wooden beam of a plow of ordinary construction, which beam plays freely between the guide-bars, which are made adjustable to receive a wood or iron beam of any thickness. G is a grooved pulley j ournaled on a stud projecting from a flanged plate, f, bolted to the pole forward of the drivers seat. To the pulley a handle or lever, H, is bolted, and to the inner side a ratchet-segment, g, is bolted, with which engages a spring-pawl, h, having a stud, t, projecting from one side, so that the driver may disengage the pawl by pressing forward the stud t with his foot.

The front end of the beam is suspended by a chain, I, whose upper end is secured to the top of the pulley at or near the handle. The rear end of the beam. is suspended from a chain, I, which passes over a sheave, k, in a slot in the rear end of the pole, passing thence over a guide-pulley, l, on the side of the pole, its other end being secured to the lower edge of the pulley.

By throwing forward the pulley-lever the plow is lowered to the ground, and by pulling it back the plow is raised, and then is held by the ratchet and pawl.

A chain, J, is secured at its front end to the side of the plow-beam near its front end. Any link near its other end is hooked to a hook,m, sliding on the vertical bar E, by means of which chain the plow may be hooked back far enough to have the furrow-slice clear the furrow-wheel as it is turned over.

To prevent the plow from rising while at work, a quadrant-stop bar, K, notched on its front edge, plays in a slot through the overh an ging end of the pole. It has a T-head, which at all times rests upon the beam. A spring-catch, a, Fig. 4, on the under side of the pole engages with any notch, and thus prevents the segment-stop from rising. The spring-catch is disengaged by a foot-lever, 0, connected therewith by a rod, 1). When the plow is lowered the spring-catch should be disengaged to allow the stop K to follow down the plow-beam.

The team is hitched to a double-tree on the end of the beam, so that the draft is direct on the beam, which is kept level by the stopbar.

The plow-beam being pivoted to the center of the axle through the swivel-bolt, the direction of the plow is not affected by the swaying of the pole.

The front beam'chain governs the depth, which is regulated by the ratchet and pawl, the rear chain being only used to raise that end of the plow.

The draft of this sulky-plow is lighter than the same plow would show Without the sulky,

partly because the friction of the plow-wheel is obviated, and partly because it takes its cut steadily without digging the point up and down, as is the case where a plow is guided by hand.

What I claim as my invention is- 1. The pulley G, lever H, ratchet g, pawl h, and chains I I ,in combination with the tongue and plow-beam of a sulky-plow, substantially as and for the purpose set forth.

2. The combination of the bolt a, swivel b, guide-bars D D, set-screws c a, eyebolt d, nuts e, and braces E E, in combination with the axle and pole to receive and guide a plowbeam, substantially as described.
