SULKY-PLO-W.

SPECIFICATION forming part of Letters Patent No 258,262, dated May 23, 1882 7 Application filedJuly 16, 1881. (No model.)

To all whom it may concern Be it known that I, ORVILLE ANDERSON STONEMAN, a citizen of the United States, residing at Minneapolis, in the county of Home pin and State of Minnesota, have invented a new and useful Improvement in Sulky-Plows, of which the following is a specification.

This invention relates to snllry-plows and it consists in the construction and combination of parts hereinafter particularly described, and then sought to be specifically defined by the claims. 7

Figure 1 is a sectional side elevation. Fig. 2is a plan view with the tongue removed; Figs. 3 and 4, detached detail views of. the swiveltongue connection; Fig. 5, a front elevation, and Fig. 6 a perspective view, of a portion of the axle and beam and its connections detached.

A is the plow; B, the beam; 0 C the sulky-wheels, and D the axle, the latter being connected to the land-side sulky-wheel O by adovetail plate, a,s1idiug perpendicularly in a dovetail groove in the hub b of the wheel and adapted to be raised and lowered and held at any point by a lever, E, dog d, and notched segment e, as shown, to adapt the sulky to the depth of cut of the plow. The axle D is provided with a crankshaped bend, D in which two curved plates, F F, are held by a screw-rod, g, tapped through both upright parts of the bend D and passing through slots in the plates F F. Nuts 9 g are placed upon the screw-rod, by which the distance between the plates F F may be adjusted to fit the beam B, which passes between them, as shown. The opposite ends of the plates F F are turned outward and upward and provided with curved ends it 7L2, by which they are secured with bolts 2" t to slots through the axle D, as shown, by which means they may be adjusted along the axle. By cnrvin g the ends h k any adjustment of the upper ends of the plates F F ortwisting movementof the beam B will cause the plates to slip or slide across the nuts on the bolts t" i and not cramp at these points, as they would if the ends were straight. When any bodily side adjustment of the plates is required, it may be accomplished by means of the slots through. the axle, besides the screw adjustment. By this means the beam is held between the platesF F ,but

is perfectly free to move up and down and row in new land or prairie'breakin g, or for any other purpose.

G is a clamp encircling the beam forward of the axle D, and connected by rods m m to the axle, near either end, by bolts n a, the landside connection a being by a slot through the axle, (see Figs. 2 and 3,) so'that it maybe adjusted to hold the axle at right angles to the beam. These rods m m thus serve to draw the sulky attachment along with the plow, and in no other manner affect or control its movement.

' H is an oblong box or sleeve, attached rigidly to the upper side of the crank part D of the axle D by a bolt, t, the sides of sleeve on the inside being angular, as shown, to permit 1 a slight degree of lateral play to the tongue,

so that the natural vibratory motion of the horses will not be communicated to the axle.

Across the tongue H forward of the-sleeve H, a short shaft, u, is journaled, and provided with arms 2; '0 upon either end outside the tongue, which are connected by rods w 10 to the clamp G, the said arms v'o being adapted to be raised and lowered and adjusted at any point by a hand-lever, M, and notched segment N, by which, through the rods w W, the forward end of the beam may be raised and lowered to set the nose of the'plow into the ground when first starting, or to raise it from the ground for any purpose. By suspending the beam between the plates, as described, and pivoting the tongue to the sleeve or cap H, as set forth, both tongue andbeam are allowed avibratory motion without communicating it to the axle.

P is a chain-wheel mounted in a frame, B, above the axleD D and connected by achain, w, to the beam B in the rear of the axle, and adapted to be revolved and set at any point by a lever, T, and segment T to raise the plow from the ground and hold it at any desired point of elevation. This chain is simply and only to raise the plow when moving from place to place, or when turning corners, and will be slack when the plow is Working.

What I claim as new is- 1. The combination, with beam 13 and axle D, having bend D of the curved plates F W, secured at their lower ends to axle D and at their upper ends within thebendD bya transverse adjusting-screw, g, substantially as set forth.-

2. The combination, with beam B and axle D, of the curved plates F F, having curved lower ends, h W, and admitting of lateral adjustment at their upper ends by means of a screw, substantially as specified.

3. The combination of axle D D beam B, plates F W, having curved lower ends, lateral adjusting-bolts d i, screw g, and nuts 9 substantially as specified.

4. The beam B, suspended in the crank portion D of the axle D between the plates F F in combination with the sulky-tongue H pivoted in the sleeve H, having double inclined walls, and secured to the crank portion D of the axle, by means whereof both beam and tongue may have a vibratory motion without communicating it to the axle, substantially as set forth.

5. The combination of axle I), beam B, and rods an M1 connecting the axle and beam, one of the rods being secured to the axle by a bolt passing through an elongated slot in the axle, by means whereof the axle and beam may be adjusted at right angle to each other, substantially as set forth.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.

ORVILLE ANDERSON STONEMAN.
