PLOW.

SPECIFICATION forming part of Letters Patent No. 332,302, dated December 15, 1885.

Application filed November 24, 1884. Serial No. 148,784.

To all whom it may concern:

Be it known that I, WM. STRAIT, a citizen of the United States, residing at Elmira, in the county of Ohemung and State of New York, have invented certain new and useful Improvements in Sulky-Plows and I do hereby declare that the following is a full, clear, and exact description of said invention, such as will enable others skilled in the art to make and use my invention.

The object of my invention is to make a sulky-plow adapted to work either on level land or on a side-hill, plowing back and forth, thus turning first a right-hand and then a left-hand furrow,and especially to prevent the plow from tipping over on a side-hill; also, to take the plows out of the ground by a power-lift; and my invention consists of certain improvements, which will be fully understood by the following description and claims.

In the accompanying drawings, Figure 1 is a top view of my improved sulky-plow. Fig. 2 is a side view without the wheels. Fig. 3 is a sectional view of one of the wheels, showing the novel construction. Figs. l, 5, 6, and 7 are detached views of parts of the machine.

In the construction of my sulky-plow I make the axle A with an arch, A, above and an inverted arch, A, below, as shown in Fig. 3, thus forming a slot in which the plow-shaft Bis allowed freely to oscillate vertically, and also to vibrate laterally in controlling the plows. Upon the axleis a pivoted double lever, O, the rear end of which supports the shaft B, which is connected to said lever by means of a box-clip, D, (shown in Fig. 1,) with the cap removed. This box-clip allows the double lever free play as the shaft B oscillates vertically or vibrates laterally. Upon the shaft B are mounted the right and left hand plows, and also the right and left hand colters or jointers. The plowstandards E have rear brackets, E, which are connected to the plow-shaft by offsets F on the eye H, and similar offsets, F, on the eye-lever G, as shown in Fig. 2, connect the standards E. The eye-lever G and eye H are capable of rotation on the shaft B for the purpose of reversing the plows. These eyes are provided with a set-ringfor holding them in place upon the shaft B. By means of these offsets the weight of the plow is thrown a considerable (No model.)

distance from the center of the shaft B and thus prevents the plow from being tipped over on a side-hill, as is liable to be the case where the weight hangs upon the center of the shaft. I have also arranged the drivers seat so as to throw the weight of the driver on the uphill side, and thus assist in preventing the plow from tipping over. The drivers seat I is supported on pivot K, as shown in Fig. 7, so as to swing or rock to the rightor to the left and be locked in place by means of a dog working into a series of notches on the arm L. The seat is made double, so that the driver may sit on either end or in tle middle. Thus by rocking the seat to the uphill side,and by the driver moving also to the uphill side, the machine is so completely balanced as to prevent it from tipping over on a steep side-hill.

The arch L or seat-support has one end resting on and pivoted to each arm of the double lever O, and two links, M M, Fig. 2, connect this pivoted or rocking lever to the elbow-lever N,which has a spring-dog working in the notched arch 0, so that the seat rises and falls as the plows are raised and lowered, and thus the weight of the driver assists in raising and lowering the plows. By means of these devices the driver can raise or lower the plows at pleasure; also, the machine is provided with a power-lift, as follows: A rocking shaftjournaled on the double lever O is provided at each end with a segmentgear, Q,which meshes into the gear-wheel z of the rim Zof the hub, as seen in Fig. 4., and a foot-lever, S, is also attached to the rocking lever P, so that the driver, by releasing the lever N, and at the same time pressing with his foot on the lever S, can bring the segment-arms into mesh with thehubs, and thus set thepower-liftinto action to raise the plows by the forward motion of the machine.

The platform T rests on braces U, extending from the axle. The poleVis made adjustable from the center to one side, for the purpose of using either two or three horses abreast.

The wheels are of novel construction, being made with awrought-iron rim, g, having countersunk holes for the spokes a, which are set bracing in a double series, as seen in Fig. 4. The hub or boX y is made with a shoulder, y, on each end to receive disks h, flanges z, having also a series of holes therein for the spokes a, which have heads on the outer ends to fit the holes in the 'rim 9, and two nuts, 6 e, on the inner ends, in order to draw the flanges 2 close upon the boxr as shown in Fig. 4. Cast upon the inner flange, z, is a gear-Wheel, 2, which meshes with the segment Q when the powerlift is brought into action. In this construction of wheel, if a spoke is broken, it may easily be replaced by first turning thenuts of this single spoke.

Having thus described my invention, what I claim isl. The combination, with the plow-shaft B and the plow-standards E E, of the eyes or collars G H, having the offsets F F, for the purpose of attaching the plow-standards to one side of the center of said shaft to prevent the plow from tipping over, substantially as set forth.

2-. The combination, with the shaft and plowstandards, of the eye-lever G G and the eye H, both provided with offsets F F, for the attachment of the plows, substantially as set forth.

3. The eye-lever G and eye H, both provided with offsets for the purpose of revolving the plows upon the shaft,'substantially as set forth.

4. In a rotating plow, the described powerlift,embracing the double lever O O, the rocking lever P, the foot-lever S, the two segments Q, and the gear-wheels 2 on the hubs, all arranged to operate together in raising the plows as the machine moves forward, substantially as described.

5. The combination,with the double lever O and the described power-lift, of the seat-supporting arch L and seat I, whereby the weight of the driver is made to assist in raising the plows, substantially as described and shown.

6. The double seat I on the raised arm of the pivotal support K, the arch L, and means for laterally rocking or adjustment for the purpose of swinging the seat and transferring the weight to the uphill side, and thus preventing the plow from tipping over, substantially as set forth.

-7. In a reversible sulky-plow, the seat having mechanism for an independent lateral adjustment to either side of the center, whereby said seat may be both made level and thrown to the uphill side or to the land side of the plow, substantially as set forth.

8. In a rotating plow, the wheel constructed as shown, and having the box y, the flanged disk 0, the combined flanged disk and gearwheel 2 and z, rim and bracing-spokes, all

arranged to operate as and for the purposes set forth.
