T0 ALL WHOM IT MAY C ONCERN:

Be it known that I, C. H. LITTLEFIELD, of Turner, in the county of Androseoggin, and State of Maine, have invented a new and useful Improvement in Sulky-Plough; and I do hereby declare that the following is afull, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, reference being' had to the accompanying drawings, forming part ot' this specitication, in which- Figure 1 is a vertical longitudinal section of my improved sulky-plongh taken in the line x fig. 2,

Figure 2 is a top view of the same.

Figure 3 is a rear end view.

Similar letters of reference indicate corresponding parts.

This invention relates to improvements in the construction of sulliy-ploughs, and consists in devices for connecting the ploughbcam with the carriage frame and the draught-pole in such mnnner that the plough may be managed while at work by the ploughman on a seat.

A A are the driving-wheels on a straight axle, B. C is the draught-pole running back and fastened to the axle Bh D is a cross-bar in front, and E E side pieces connecting `the cross-bar with the axle B, forming together the truck or carriage for the plough. F is the plough, which may be of any ordinary make, and is attached in the usual manner, to a plough-beam, G, upon which is a clevis, a, connected with the pole C by a draught-chain, b. The front end of the plough-beam is provided with an adjustablcguide-wheelc, and to the rear l end is fastened a single plough handle, d, which passes up vertically in front ofthe drivers seat H mounted on the rear ends of spring bars e e. Avertical slotted iron guide g is made fast at the upper end to the front cross-bar D, near the draught-pole C, and a similar guide, g', is p'ivoted at the upper end to the axle B so as to have a late ral vibration. A rod h passes through two eye-bolts z'z' in the front and back ends of the ploughbeam, and also through the slottedA iron guides y for thc purpose of holding the plough F in place, while at the same time it is allowed to have play enough for working both endwise and sidewise. It will be seen that the rear guide g', by its lateral movement, enables the driver in his scat to cant the plough to one side or the other as required by means of the handle d, while the rod h can'also move freely in the guides g g in several directions. In the rear guide g', is a notch, It, on one side of the slot, in which the rod can rest when the plough is lifted clear of theground for going afield or turning about, and the front end of the plough-beam G is connected by a chain, m, with a lever, n, that extends back to the axle B, by which the driver may lraise the plough-beam in front, and hold 'it with his foot down, when desired. By these arrangements the plough is completely under the control of the driver, and the ploughing lcan be performed with much greater facility than in the ordinary iiay.'

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

The slotted iron guide g made fast to the crcss-bar D, and the vibrating iron guide g', connected with the axle B, in combination with the rod h, and plougheheam G, arranged and operating substantially as and for the purposes herein described.

C. LITTLEFIELD.
