MARTIN L. KISSELL, or SPRINGFIELD, OHIO, ASSIGNOR TO THE P. P. MAsT & ooMPANY, OF sAME PLACE.

HOE FORIGRAIN-DRILLS.

V. 4 To all whom at may concern:

Be it known that I, MARTIN L. KISSELL, a citizen of the United States, residing at Springfield, the county, of Clark and State of Ohio, have'invented certain new and useful Improvements in Hoes for Grain-Drills, of which the following is a specification, reference being'hd therein to the accompanying drawings. 1"

This invention relates to improvements in hoes for grain-drills, and has special reference to thefarrangement and construction of those features which enter into the'organization of a spring or yielding connection between the hoe arid its beams or draft-bars. I am aware that, broadly considered, a spring or yielding connection between such hoes and their draftbarspby means of which the hoes are allowed to give or deflect when obstructed by objects which afford greater resistance thanthe normal s'trains brought upon th'ehoes as incident to the ordinary operation of drilling grain, is old; and therefore wish to'be understood as laying claim to my improvements in the light of the state of the art as at present developed.

In the accompanying drawings, forming a part of this specification, and on which like reference-letters indicate correspondin g parts, Figure 1 represents a sectional View of a graindrill and a hoe and its draft-bar with my improvements applied thereto; Fig. 2, an enlarged plan View of my improvements in connection with a hoe and its draft-bars; Fig. 3, a longitudinal sectional View on the line w w of Fig. 2, and Fig. 4 a detail perspective view.

of a stop-lever.

' The letterA designates the essential portion of a grain-drill frame'of any approved construction, but preferably of the type manufactured and sold by my assignees of this invention, P. P. Mast & Company, of Springfield, Ohio, and in which are embodied two adj ustable transverse beams B and O, to which the forward ends of the hoe draft-bars are pivotally connected, the draft-bars alternating from first one and then the other of the beams B and C. By preference these draft-bars are composed of separate pieces D D, and at their rear ends they are connected by a pivot-pin E to a suitable part of the wing F, extending from the hoe G, which is of the usual or any SPECIFICATION forming part of Letters Patent No. 404,845, dated June 11, 1889. Application filed Fehruary 16, 1889. Serial ITO-300,136. (No model.)

approved type. This wing has a series of holes H for the reception of the usual fragile or wooden brake-pin I, the function of which is Well known. To the lower forward portion of the Wing F is pivoted two links Jone at either side of the bolt K. These links extend upwardly and forwardly from this pivot-bolt a suitable length, and are pivotally connected to the upper forward side pieces of the stoplever L, as suggested at M. This stop-lever is composed of two side pieces L ,a body portion M, curved upward at its rear end, as seen at O, and of a short stout arm P. These several parts are by preference integral, and may be cast-iron, malleable iron, or may be forged of iron, or they may be constructed of steel.

I term the device a stop-lever, because it acts in the capacity of a lever and in the capacity of a stop to preserve the normal and proper relations of the several parts by engaging with the under edge of the draft-bar, as seen at Q in Fig. 3, in which the parts are in normal position. f' It will-be seen from Figs. 2 and 4 that the arm P is located nearer one of the pieces L than the other, so as to accommodate the rear end of the spring-rod R, which is pivotally connected with the arm P by a pin S. The stop-lever is itself pivoted to the draft-bar by a pin or bolt T,which passes through the portion 0 and through the pieces L. A clear idea of the arrangement of the parts may be gotten from a view of Fig. 2. The relative position of the pivots K, T, and M will also be clearly seen from Fig. 3, from which it will be observed that-the pivot T. is slightly above a line drawn through the centers of the pivots K and M. This relation of the 0 pivots, it will be understood, is necessary in order to bring the strains sufficiently to one side'of the pivot T to turn the lever on that pivot when the hoe is unduly obstructed, as suggested in Fig. 1, in which a stump is illus- 5 trated as located in the path of the hoe. The brake-pin gives away, and the strains are then thrown upon the spring-rod, the connection of which through the spring U, about to be described, brings the hoe back to nor- 10o inal position, as suggested in dotted lines in Fig. 1. The spring U is of spiral type, and

is placed around the rod Rbetween a washer V, held by a nut NV, and a plate X, secured to and between the draft-pieces D of the draftbar. A hook Y may be formed on the upper end of the plate X, for engagement with the device for lifting and sustaining the hoes when not in operation.

It will be observed that my improved arrangement and construction avoids the proj ection of parts to any considerable distance above the draft-bar, and that when the parts are swung to the position shown in Fig. 1 they are all below the draft-bar save the hoe, which is at the rear of the axle Z. This arrangement is important and of value in practice, because it admits of the draft-bars being raised up to the axle without obstruction from the parts of the spi'ingconneetion, whereby higher stumps and otherobjects can be passed over by the hoe without breaking one or more parts of the machine, as is the case when a hoe lodges on a high stump, or other high obstruction, and raises the draft-bar high enough to cause the parts which project above to catch on the axle before the hoe is over the stump or other object. hen this latter occurs, some vital part of the machine is almost invariably broken, and delay and expense of repairs incurred, and this probably at a time when most inconvenient to the farmer. By my improvements, however, this trouble is entirely avoided by the absence of the parts projecting above the draft-bar when thelatter is thrown up. I

It will also be observed that-the stop-lever L is a cheap and strong device, admirably adaptedto its functions, and doing the double oifice of a lever and a stop.

The brake-pin may or may not be used. The holes in the wing are simply provided so as to temporarily use the pin in case of breakage in the spring-conn ection until such breakage is repaired.

Having thus fully described my invention,

what I claim as new, .and desireto secure by Letters Patent, is

1. The combination, with a hoe and its draftbar pivotally connected to it, of a spring-rod carried by the draft-bar, a lever pivoted to the draft-bar at one end, links pivoted to the hoe and to the other end of said lever, a stop constituted by said lever between said last pivots, and a pivotal connection between the lever and the spring-rod.

2. The combination, with a hoe and its draftbar pivotally connected thereto, of a springrod carried by the draft-bar, a lever composed of an upwardly-turned rear portion pivoted to the draft-bar, abody looked under and across the said bar and side pieces at the sides of said bar, and an arm within the draftbar, a pivotal connection between the said arm and the spring-rod, and links pivotally connected with the hoc and with the said side pieces of the lever.

3. The combination, with a hoe, its draft-bar composed of two pieces pivoted to the hoe, a plate and rod between said pieces, a spring between the plate and an enlargement on the forward end of the rod, a stop-lever composed of a rear upwardly-extending portion pivoted to said draft-pieces, an arm extending from said portion andpivoted to said rod, a body beneath and across said draft-pieces and side pieces, and links pivoted to the upper forward ends of the side pieces and to the hoe below its pivotal connection with the draft-pieces.

4. A stop-lever composed of a horizontal body portion, side pieces extending above said portion, a rear upwardly-extended part,

and a short arm projecting forward from said part, all of said parts being integral.

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

MARTIN L. KISSELL.
