UNITED STATES PATENT O FICE.

EBENEZER B. FARNSWORTI-I, OF OAKFIELD, NEW YORK.

cu LTIVATOR.

SPECIFICATION forming part of Letters Patent No. 506,171, dated October 3, 1893.

Application filed July 28, 1893. Serial No- 481,761. (No model.)

To all whom it may concern:

Be it known that], EBENEZERB. FARNS- WORTH, a citizen of the United States, residing at Oakfield in the county of Genesee and State of New York, have invented certain new and usefullmprovements in Cultivators; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which.

it appertains to make and use the same, reference being bad to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to certain new and useful improvements in cultivators of that class in which the axle is broken or rather in which the wheels are carried by stub axles which are mounted for pivotal or swivel movement.

It has for its objects among others to provide a simple and cheap improved construction of this character by which the cultivator shall be held in a straight-forward position and when turned by pressure of the foot of the operator from this position shall be automaticaily returned thereto as soon as the said pressure is removed therefrom.

As will be hereinafter clearly seen the inner ends of the stub axles are connected by a cross piece which is pivotally connected thereto and which is acted upon by a spring which may be a flat or a coiled spring, the other end of which is attached to some fixed part of the frame.

My improvement can be readily applied to cultivators now in use with small cost and but little change in the construction thereof.

Referring now to the details of the drawings by letter, A designates the stub axles upon which the wheels are designed to be carried, the stub axles and wheels being of any well known or approved forms of construction.

B is the frame of the cultivator, also of any suitable form of construction, and atits rear end connected by the cross piece 0 which is extended beyond the side bars of the frame and to the extended ends are secured the bearings D for the vertical pintles or pivots d of the stub axles, which pintles are held therein in any suitable manner so as to allow the axles to move freelyin either direction. Each of the stub axles has either secured thereto or integral therewith the centrally projecting and upward and forwardly extending preferably curved arms F the upper ends of which terminate above the frame and are pivotally connected by the cross bar or piece G which rides over the side bars of the frame of the cultivator as seen in Fig. 2.

H is the pole or tongue secured to the front cross bar of the frame and to the rear cross piece 0 in any suitable manner; the cross piece G is confined between this pole or tongue and the side bars of the frame but is free to move transversely of the machine. It is to be moved by the foot or feet of the operator by pressing thereon.

I is a spring one end of which is secured to the pole or tongue or to some other fixed part and its rear end is arranged to act upon the cross piece G as shown. This spring may be of any desired or suitable construction, but is preferably a flatspring plate or bar set upon edge and its rear end passed loosely yet confinedly between the pins f which are held in the cross piece G as shown. In the absence of this spring there is nothing to guide the wheels or cultivator except the feet of the driver but the spring furnishes a yielding hold for the wheels and yet allows the wheels to be easily turned to guide the cultivator to the right or to the left and then quickly returns it to its correct position as soon as the pressure or weight of the feet is removed.

WVhat I claim as new ist 1. The combination with the frame and broken axles pivoted as described, of a bar connecting the axles, and a spring secured at between pins upon said cross bar, substan- IO tially as and for the purpose specified.

In testimony whereof I affix my signature in presence of two witnesses.
