IMPROVEMENT IN SULKY-PLOUGHS.

TO WHOM IT MAY CONCERN:

Be it known that I,-1E1 \VITT HUNT, of Wcathersfield, county of Windsor, in the State of Vermont, have made new and useful Improvements in Sulky-Ploughs; and I hereby declare the following to be a full and exact description oi" the same, reference being had to the drawings that accompany and form a part of these' specifications. A, i

The object of my invention is to provide a new mode of draught and working of a plough, so that one person can operate and control the same with perfect case. It is'designed to be worked with two horses.

Figure 1, top view,

Figure 2, side view on a line of the draught, with the right wheel removed.

Figure 3, view of oval axle holding the beam E.

Letter A, axle, to which is attached a frame, extending forward, and on which the drivers seat, G, is placed. The'forward bar, B, of this frame extends in front of the right-hand wheel, and to this bar the pole C is attachedj. just within the line of the wheel. 7 i

To the under side of the pole, the whifllo-trec is secured by a bolt, extending through it, and a slot, d, in

the pole. i

To the axle A is hinged a. beam, or lever D, extending back, and to which the beam E of the plough .is

attached by an oval axle, e, shown in fig. 3. An iron brace,f, attached .to, the lever D, and hinged to the axle, serves to hold. and keep it in a direct line.

The plough is attache-l to the short beam E, in which is a slot S, to admit the oval axle c. This slot isfof corresponding length with slot d in the pole, and provides for aslight movement of the carriage forward, and obviates any sudden jerk should the plough come in contact with any permanent obstruction.

The oval axle provides or allows a pitch of a limited numberof degrees to the plough. Large iron washers, It, held firmly by a bolt through the oval axle, secure the plough-beam to the leyer D, and prevent any side movement. I

A draught-chain, F, extends-from the beam E tothe whifile-tree, and attached to a hoolr onthe same. By means of a short chain, 2', attached to the beam E, extending vertically, one can adjust the depth and pitch of the plough by lengthening or shortening'the chain on the hook 1t, placed on the beam D for that purpose.

Extending from the bar B, on a line with the'beam or lever D, projecting back of and resting upon the top of the axle, is a bar, It. This bar supports an iron lever, Z, which is hinged in the beam 1), the fulcrum being at p, in the bar It. The lever l is provided with a ratchet-bar, m, passing through a slot in the bar is, in which is placed a bolt or pin to hold the lever at any point desired, and by this lever the plough is raised or lowered. At the lower end of the ratchet-bar is a stirrup, so it can be operated by the-foot of the driver.

The wheels should be made with broad rims or felloes, but they are calculated to run on the unbroken ground, the furrow being turned over directly behind the wheel. The depth we desire the plough to go having been adjusted by the means heretofore described, the driver takes his seat, and has only to place his foot in the stirrup, relieving the lever Z, which allows the plough to drop, and is easily raised to avoid any obstruction, or when turning at the end of the furrow, by the same means, aided bythe hand upon the lever.

What I claim, and desire to secure by Letters Patent, is-- 1. The hinged beam D, and the plough-beam E, provided with and connected by the oval axle e, and the chain 1', or its equivalent, substantially as described and set forth.

2. The combination of the iron lever [with the bar It and the beam D, substantially as and for the purposes set forth. r 3. Providing the beam E and the pole C with the slots S and cl, to act in conjunction, thereby giving the plough some longitudinal play, when the beam E is connected to the whiflle-tree or bolt t, by the chain 13, or its equivalent, substantially as described and for the purposes specified. I v

In testimony whereof, I have signed mv name to this specification in the presence of two subscribing witnesses.

. LEAVITT HUNT.
