IMPROVEMENT 1N CULTIV'ATORS.

l'To all whom 'it may concern: l

Be it known that I, GEORGEJ. HAYES, of Iona, in

-the county oionia, and State of Michigan, have invented certain new and useful Improvements inWheeled Gultivators; and that the following is a full, clear, and

.exact description ofthe construction and operation ofthe same, reference being had to the accompanying drawings,making a part of this specification, `in which- Figure 1 represents atop plan of the cultivator, and

Figure 2 represents a side elevation, with 'the near wheel removed or cut away, to betten show the parts behind it.A t,

Similar letters of reference, where they occur in the separate Iigures, denote like parts of the machine in both of .the drawings. p

My invention consists in the manner in which I have constructed and arranged the tongue, axle-frame, cultivator-frame, and drag, or har-row, so that the attendant may have the cultivator and drag' entirely within his control, bynieansv of the hinged connections between the several parts, and levers connected to' then'i, as will he hereafter explained.

To enable ot-hers skilled in the art to make and use my invention, I will proceed to describe the same with reference to the drawings. f

The axle A is supported in two wheels, B B, in the usual wellknown way.

The tongue G is. pivoted to the axle, so that it may have some motion independent of the axle, and upon a portion of the tongue, extended -in rear ofthe axle, is placed a seat, D, for the driver, or conductor, when riding upon the machine.

Two pieces E E are permanently framed in or fastened to the axle A, and so inclined `toward each other, at their front ends, as to serve the purpose of hounds or lateral braces to thel tongue, but not .fastened to the tongue; and their rear ends aieso spread as to form supports for the rear end of the cultivator-frame F, which is suspended thereto by rods a a. e p

The axle A, and the oblique pieces E E, secured to it, Iterin the axle-flame. 'lhe tongue is not=included in this frame, for, though united to the axle, it is not rigidly connected to it. i i

On the tongue C is placed. a standard, b, to which is permanently fastened a plate, c, that has reversed i ratchetfteeth, 1 2, on its upper edge 5' and to this standard is pivoted a three-armed lever, G, to which a reversible dog, d, is pivoted, so as to take into the teeth of either ofthe ratchets, as the case may be.

The'arm 3 of the .lever G is connected to the 'ont ends of the pieces E E, by a bail or bracket, e, and to the arm 4 of said lever is pivoted a rod or; bar, f, to the lower end of which the culti'vat'or-frame F is pivoted and suspended, said bar j' projecting forward of a perpendicular line drawn throughits connection with the arm 4, as seenin iig. 2, so that the raising up of the cultivator-frame shall also give it backward direction, and freeing the points of the cultivator-teeth g from the'soil, and, notwithstanding the machine may be moving forward, allowthem to freely clear any ob` struction. I

From this construction, it will be perceived that the front ofthe cnltivator-franie is suspended to the tongue C, whilst the rear of said frame is suspended to the pieces E E of the axle-frame.

The arm 5 of the lever has a handle uponit, so that the operator, from his seat, by drawing /the lever toward him, raises the cultivator-iiame upward and back ward, and then, by throwing. the' dog over on to the ratchet 2, the said' frame will be held in its raised-up position for transportation, or for turning the machine around; and when the teeth g are let down iuto'working-position, the dog is thrown over-.on Yto the ratchet4 l, audrthis :prevents the frame from rising when the teeth run into hard ground, or the frame tends to rise by meeting any resisting obstruction.

The rear ofthe frame F is raised up by forcing down the forward ends of the pieces E, and raising their rear ends by the rolling of the axle in its wheels.

vTo the rear of the cultivator-frame Fis hung, by arms h, so that it may swing thereon, a har, H, in

Y which there is set a series ot teeth, fi, so as to form a drag, or hairow, for pulverizing the soil that the cultivator passes over. i

To this bar,'or harrow, is connected a lever, Lwhich extends upward, and within the reach of the rider upon the seat D, so that he may seize it, and raise up the drag, or har-row, and, by means of a catch, j,.on the axle, hold it up permanently, when desired to do so, or let it down again. When the cultivator-frame is raised up orlet down, the harrow moves with it, but the harrow can he thrown up out of action, whilst the cultiVator-teeth continue to cultivate the ground.

. J are standards, or stocks, for the cultivator-teeth-g, and these stocks are braced by rods 7c k.

The double-tree on is connected to the cultivatorframe F through the piece F and strap n, which are attached to said frame.

lf the attendant desires to walk behind the machine, he can do so, and raise and lower the teeth by a very simple change of parts, and the addition of one lever,

Yplaced upon the rear ofthe tongue, and inclining rearward, Ato which a rope, or cord, is united, and extends to and united with the lever G, so that, by operating 'the one on thetongue, he can operate the one, G, as

readily as though he were in the seat D; and, when walking, the lever I may be removed from its seat on the top of the har H, and put into a similariseat, or hole, in the rear of said bar, so as to raise and lower the drag.

o o are braces, for bracing the suspension7straps a a to the axle.

Having thus fully described my invention,

1. lhe combination of the tongue, axle-frame, and cultivator-frame, when united to each other, and the eultivator-frame is capable of being raised upward, and

` swung slightly backward, by a lever and its appliances,

operating as herein described and represented.

2. Also, in combination with a. cult-ivator-frame, that is moved backward as it is raised upward, as herein described, a drag, or barrow, attach ed thereto,and moving therewith, but capable of being raised or lowered inde' pendent of the cultivator, substantially as and for th purpose described.
