CULTIVATO R.

SPECIFICATION forming part of Letters Patent No. 340,744, dated April 27, 1886.

Application tiled September 15, 1885. Serial No. 177,171. (No model.)

To @ZZ whom, it mayeoncern:

Be it known that I, FELIX PARKS WAR- REN, a citizen of the United States, residing at Mulberry, in the county of Lincoln and State of Tennessee, have invented a new and useful Improvement in Cultivators, or" which the following is a specification, reference being had to the accompanying drawings.

My invention has relation to improvements in cnltivators; and the novelty consists in the peculiar construction, combination, arrangement, and adaptation of the various parts for service, substantially as hereinafter fully set forth, and specifically pointed out in the claims.

The object of my invention is to provide a eultivator the blades of which are adjustable vertically in the earth or soil, to provide for lateral adjustment of the teeth or blade snpporting-bars to enable the blades to tor work in furrows of varying distances apart, and to provide means which shall combine simplicity, strength, and durability of construction with thorough effectiveness of operation and cheapness of manufacture.

l have shown an embodiment of my invention in the accompanying drawings, in which Figure lis a side elevation of a cultivator constructed in accordance with my invention. Fig. 2 is a plan view. Fig. 3 is an enlarged detail view of the cultivator-blade and its adjusting mechanism.

Like letters of reference in the drawings denote corresponding parts in all the figures, referring to which, A designates the beam, which may be provided with a clevis, A', at its front end -for the draft, and B designates the handles connected at their upper rear ends by a cross-bar, B', and secured upon the cultivator-blade supporting-bars C C. The cultivator-bars C C are bent near their front ends, as at c, and bolted to the beam A by means of throughbolts c', having nuts c2, one of said bars, C, being longer than the fellow bar, C. Each of the bars C C are curved downwardly at their rear ends and bifurcated, as at d, and between the arms thereof are pivoted the arms D, as at d', which are provided with the cultivator blade or tooth D', of the usual or any preferred construction,and bolted or otherwise suitably secured thereto.

E designates a supporting-plate having a series of apertures, c, with one of which the nib or tooth f of a hand piece, F, is adapted to engage, said hand piece orlever being pivoted, as at f', upon a carrying lever or arm, G, and pressed normally outward and in engagement with said supporting-plate E by means of a spring, F', rigidly secured at one end to the carrying or adjusting lever G and bearing against the band or ngerpiece at its free end, as will be very readily understood.

rljhe carrying-lever G is pivoted to the front ofthe plate E, as at g, and at its front end it carries an arm, H, which is pivoted thereto, as at 71., and bifurcated at its lower end, as at h', and pivotally connected to the arm D beyond the pivot d thereof and near the point where the blade is secured thereon. The arm or link H passes through a bracket or guide, E', secured to vor formed with the extension E2 of the supporting-plate E, and said arm H is provided with two or more apertures, h,at its upper end, whereby said parts may be adjnsted.

The lower ends of the handles B are connected to the bars C by means of bolts I, the heads of which, t', are fitted in recessed portions j, of the rear end of the beam A and held in place bymeans of a cap or cuff, J, adapted to embrace said beam. The outer ends of the bolts are passed through the arms G and the lower ends of the handles B, and are each provided with two nuts,fi i,arranged to bear one on the bar C and the handle,to clamp the parts in position and permit the bar C and handles to be adjusted outwardly and laterally, to accommodate the shovel-blades to varying widths of furrows.

K designates braces having apertures or holes k, through one of which passes a securingbolt, K', and through the handle. Said handles are secured at their lower ends to the bar C, thus enabling the handles to be adj usted up or down to suit the requirements of the operator.

It will be observed that the cultivaror blades and arms can be adjusted vertically to any depth in the soil by simply Vdisengaging the locking pin or bolt of the linger-piece from engagement with its aperture of the supporting-plate E,and moving the pivoted carryinglever F up or down, as may be required,

IOO

which will elevate or depress the arm or link connecting with the blade-carrying arm D,and move or adjust the said arm accordingly.

The parts are very simple, strong, and durable in construction, efficient, easy, and positive in operation, are not liable to displacement or breakage, can be manufactured and supplied at a minimum of cost, and require but a minimum of power for successful operation. i

I am aware that it is not broadly new to vertically adjust the blades of a cultivator nor to provide an operating-lever therefor, and hence I disclaim this construction, broadly.

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

1. In a cultivator, the combination of a beam, a supporting-arm rigidly secured to the beam, a shovel-arm pivoted to the rear end of the supporting-arm, a perforated plate mountf ed on the supporting-arm, an operating-lever pivoted to the perforated plate and carrying a pivoted springactuated arm or latch adapt ed to enter one of the perforations of the plate, and an arm or link pivotally connected to the front end of the shovel-arm beyond the pivots of said lever and shovel-arm, as set forth.

2. In a cultivator, the combination of the beam,supportingarms rigidly secured thereto and curved and bifurcated at their rear ends, shovel-arms pivoted between the bifu rcated ends ofthe supporting-arms, perforated plates E, rigidly secured upon the supporting-arms, operating-levers pivoted to the supporting`- plates, an arm or latch, F, pivoted on the operating-lever and normally pressed into engagement with one of the apertures of the plate E by a spring, a link or arm, H, pivotally connected to the lower end of the shovelarm and adjustably and pivotally connected to the free end of the operating-lever beyond its pivot, and guides E', for said connecting link or arm, substantially as described.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.

FELIX PARKS WARREN.
