IMPROVEMENT I N CULTIVATORS.

Specification forming part of Letters Patent No. 179,220, dated June 27, 1876; application filed June 14,1876.

To all whom it may concern:

Be it known that I, GEORGE W. RHODES, of Etna, in the county of Tompkins and State of New York, have invented certain new and useful Improvements in Cultivators; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to which it appertains to make and use the same,'reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

The object of my invention consists in pro-' viding a self-adjusting attachment to a cultivator, whereby it is raised fromthe ground or folded at any time, enabling the operator to turn it safely at the ends of the rows without injury to the plants, or to easily transport it from place to place.

' In the drawings, Figure 1 is a top or plan View of my cultivator. Fig. 2 is a side elevation.

A represents the longitudinal pieces of frame; B, cross-sills uniting the pieces A, and to which the teeth are attached. 0 represents the teeth. D is the handle or lever; E, brace from tongue to handle or lever. F is the tongue and G block, for connecting brace with tongue; H, roller to tongue; I, pin in lever for holding brace; K, wheels.

The frame of my cultivator is constructed by uniting the longitudinal pieces A by thecross-sills B, to which the teeth are attached, and the number of cross-sills correspond with the number of teeth employed.

This cultivator is intended to be operated by two horses, and is designed to cultivate both sides of a row at once; and in the arrangement of the teeth the two center ones, or the ones designed to run nearest the row, are preferably placed in front, each alternate tooth being placed on the opposite end of a cross-sill. The teeth are also improved by extending the base an inch or more beyond'the standard in front, so that both the toe and heel project, and they are held firmly in place by slight projections on their upper side, which are let into the Wood of the frame.

On each end of the front longitudinal piece A is fixed an axle or arbor, upon which wheels hinge. I do not, however, confine myself to this construction. Any other suitable hinge which will accomplish the same purpose may be employed. These hinges are directly over and nearly on a line with the points of the front teeth, and at a short distance in rear of theline of the wheels K.

By this arrangement the resistance of the front teeth, operating in connection with the draft of the team, causes the cultivator to tilt forward and rest upon the wheels. In order to provide against the tilting motion and keep the teeth in the ground when the cultivator is in operation, a brace, E, is employed, which extends from the tongue over the handle or lever D. This brace consists of two straight or curved pieces, so joined that a space is left between-them, through which the handle or lever passes, and its end is pivoted to the block G on the tongue, at a distance of about two feet in front of the cultivator. This brace may be constructed of woodor iron, as deemed advisable. When the cultivator is in position to be operated this brace extends over the handle or lever, and is held in place by a pin, I, through the lever, which engages in a notch, J, on the under side of the brace. A corresponding notch, J, at some distance in front of the first, is also provided, so that when the end of the row is reached, and it is desired to turn without danger of the teeth tearing out the plants, the brace E is disengaged from the pin I by a slight movement, and the draft of the team, operating in connection with the resis'tance of the front teeth, at once tilts the cultivator, and throws it forward on the front wheels, in which position it is securely held by the notch J of the brace E, which drops over the'pin I. It then rests upon the wheels,

and may be readily and easily turned or transported from the field. It is easily thrown back into position by a slight backward movement of the team, or by the hand after disengaging the pin from the notch J.

I am aware that a cultivator provided with a tongue, wheels, and stay-bar or brace, and arranged to tilt forward, so that the teeth are lifted from the ground, substantially-as shown in the patent, No. 102,201,0f0. Alvord. has been heretofore used, and is not new, and I do not claim this principle, broadly.

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

In a cultivator, the arrangement of the different parts, consisting of the frame A B, thetongue F, having the roller H, the wheels K,
