UNrrnD STATES PATENT Ormea.

CALEB M. RISLEY, OF WOODBURY, NEW JERSEY, ASSIGNOR OF ONE-HALF TO CLAYTON B. ROGERS, OF PHILADELPHIA, PENNSYLVANIA.

CULTIVATO R.

SPECIFICATION forming part of Letters Patent No. 248,954, dated November 1, 1881.

Application tiled May 7, 1881. (No model.)

To all whom it may concern Be it known that l, GALEB M. RrsLEY, a citizen of the United States, residing at roodbury, in the county of Gloucester, State of New Jersey, have invented a new and useful Improvement in Oultivators, which improvement is fully set forth in the following specification and accompanyingdrawings,in which- Figure l is a side elevation of the cultivator 1o embodying my invention. Fig. 2 is a front view thereof. Fig. 3 is a bottom view of a detached portion enlarged.

Similar letters ot' reference indicate corresponding parts in the several figures.

My invention consists of a guide applied centrally to a cultivator in the longitudinal direction thereof, whereby the cultivator will be run uniform and steady and the depth of penetration ofthe hoes may be limited.

2o It also consists of the head at the forward end ofthe cultivator, having adovetailed connection with the center bar of the frame of the cultivator, and provided with an eye for the attachment of the bolt for the draft-rod.

Referring to the drawings, A represents the frame of the cultivator, consisting of the central bar, B, and side bars, O O.

D represents a casting or head for the front of the frame, consisting ofthe dovetailed box 3o or part a, to which the front end ofthe central bar, B, is fitted, said end being also-of dovetailcd form, the side eyes, b b, to which the side bars, C C, are pivoted, and the front eye, d, through which the bolt c ofthe draft-rod E is passed. The bottom ofthe head'has a closingplate, j', which, when bolted in position, firmly connects the center and side bars, B C, and the head, and separation of the parts is prevented. This feature of my invention is serv- 4o iceable, as it prevents or obviates drilling or piercing the center bar in the broad direction of said bar, such drilling or piercing` being a difficult operation and weakening the bar.

F represents a guide, formed of suitable metal, of the longitudinally-extending bottom bar or runner, g, and uprightend pieces,7t, the front onc whereof is pointed or sharpened.

The end pieces, h, depend from and are secured to the central bar, B,of the frame or other suitable portion of the frame in such manner that 5o the bottom bar occupies the center of the cultivator about the lower line of' the hoes above, below, or on the level with the same, as desired. l

It will be seen that when the cultivator moves forward the point of the guide enters the ground, and the bottom bar or runner, following the same, provides, as it were, a centra-l support in the ground for the cultivator, so that the cultivator runs uniform and steady, 6o obviating the usual roughness and irregularity of motion in implements ofthe kind.

The end pieces, h, are adjustably connected to the frame, so that they may be raised and lowered, thus providing means for adjusting the height ot' the bottom bar or runner, g, relatively to the nature of the work to be accomplished and the desired depth of penetration 0f the hoes.

The guide as constructed is of skeleton form, 7o whereby it is light and durable, and may be made of a single piece of wrought-iron or of properly-shaped sections fitted and secured to each other as desired.

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

l. A cultivator-t'ra-me having center bar, B, and side bars, C, in combination with a skeleton-guide, F, consisting ot' a horizontal bottom 8o bar, g, and'two standards, 7L h, one at each end, said standards being secured to said center bar at their tops.

2. The center bar, B, having a dovetailed forward end, in combination with the head D, having'dovetailed recess a and side eyes, b, the platef bolted to said head, and the side bars,

O, pivoted between said head and plate, substantially as set forth.

CALEB M. RISLEY.
