JOHN J. LARSON, OF CLARION, IOVA.

HORSE-EVENER.

SPECIFICATION forming part of Letters Patent No. 795,140, dated July 18, 1905.

Application ile. September 30, 1904. Serial No. 226,702.

To all whom, it may concern.'

Be it known that I, JOHN J. LARsoN, acitizen of the United States, residing at Clarion, in the county of Wright and State of Iowa, have invented new and useful Improvements in Horse-Eveners, of which the following is a specification.

This invention relates to draft-equalizers generally, and more particularly to those used in plowing and in reaping' and binding, and cutting grass, Sac.

\/Vhile it will appear plain from the description hereinafter g'iven that'my invention may be embodied in various forms of means, that shown in the drawings is one of the best now thought of by me, and as it serves well to make clear the construction and operation of the said invention the description -will be closely conlined to the said drawings without any purpose of so limiting' it.

As shown, the invention is adapted for the employment of three, four, or live horses, 'and its object-is, first, to equalize the draft so as to draw the machine straight ahead. irrespective of the position of the horses; second, to enable five horses to be hitched side by side, giving room for one horse to walk in the furrow and the others on the solid unplowed ground; third, to enable four horses to be hitched to the evener so as to draw a reaper and binder in proper line, the horses walking side by side, with none working in the grain; fourth, to provlde various improvements in the construction and arrangement of parts to secure betterments in the mode of operation of the contrivance, as will clearly appear from tho description and claims.

Reference is to be had to the accompanying drawings, and to the symbols of reference marked thereon, forming'a part of this specification, the same symbols designating Athe same parts or features, as the case may be, wherever they occur.

Of the said drawings, Figure 1 is a perspective view of the invention as it may be constructed and arranged for the employment of live horses and in which the vertical extension is pivotally and adjustably connected to the beam extension, shown, for example, to consist of two plates attached together at their ends and passing outside the main beam or tongue. Fig'. 2 is a perspective view of the invention, showing it as equipped for four horses and showing an instance in which the vertical extension is notfpivotally connected with the means drawn upon, but turning on a pivot connected with the same. Fig. 3 is a perspective View of the lateral draft-beam and the pendent casting or vertical extension for connecting it with the plow-beam or other means drawn upon through the intermediaries shown and described. a modified form of means for securing the plow-beam A with the vertical casting As before stated, the invention is designed for use on reapers, gang-plows, and farm implements generally that are to be drawn by horses, so that whether we consider the means shown as connected with a plow-beam or means for drawing a reaper or binder it will make the application of the invention to other uses so plain that no reference thereto need be made.

,In the drawings, Adesignates a plow-beam or reaper-tongue, and a is a draft-beam provided at its inner end with a vertical casting 7), which is adapted to eXtend between two forwardly-extended castings e f, Fig. 1, and to be connected thereto by a bolt passed through the holes c. There being a series of these holes c in the casting t it will be plain that it may be adjusted through these means in higher or lower position in the beam or tongue A or through intermediaries with the said tongue. As shown in Fig'. 2, the casting 7 is passed through a simple slot formed in the frontend of the beam, and it is held in place bya pivotor bolto' (see Fig. 2) in the eye-casting n, secured beneath the beam. Having reference again to Fig. l, the castings c f at their rear ends are connected to a draftplate a' by a bolt g, and it will be seen that under the construction shown in this ligure it may be adjusted at a higher or lower level through the medium of the series of holes formed in the said draft-plate. There may be two draft-plates connected with and extending forward from the end of the beam A, one on each side thereof, as shown in Fig. l, in which case castings d e will be pinned or Fig'. 4t illustrates Iol bolted to the draft-plates ct a' and extend forward on opposite sides of the vertical casting b, to which they may bebolted. The brace f, connected at one end to the casting d, is connected at the other end to the draftplate, to which they casting d is secured, and Serves as additional support to the latter. It will also be noted that the said two plates, which are connected at their ends, form an extension to the rnain beam or tongue, pass outside the said tongue. Shouldasingle casting be employed to connect the draft-plates with the vertical casting L, the latter may be modified in construction, as shown in Fig. 4, in which it is shown as provided with a slot c2, and the single casting d extended therethrough and bolted thereon. /L is an extension-piece connected with the lower end of the vertical casting I) and projecting laterally therefrom, and the draft-bart' is connected with the said casting ata point corresponding substantially Withits longitudinal center by means of aclevis j', and adoubletree o islikewise connected at the outer end of the draftbar t, While swingletreep p are connected to the ends of the doubletree o through the medium of clevises and aswingletree p2 has a clevis connection with the inner end of the draft-bar In Fig. l I have also shown the draft-bar ct as having adoubletree t', connected with its outer end by means of a clevis l, and swingletree p3 p4 as having a clevis connection with each end of the doubletree 7a'. Under this construction it will be seen that [ive horses may be used in the draft of the machine or farm implement, (say, for example, a plow,) and that by a proper adjustment of the parts the line of draft will be from the pivotal point 0 straight forward. The extension-piece t in this case performs an importantpart in securing equalization of draft on the pivot c.

By the construction shown in Fig. 2 it is intended to hitch but one or two horses to the vertical casting which may be accomplished by means of a doubletree or swingletree, and which is connected by a clevis directly to the said vertical extension Z). In this case, as well as the former, the draft will be directly forward, as will be indicated by the lead-lines leading to the reference-letter in Figs. l and 2.

It will be understood, of course, that all of the parts requiring to be made adjustable will be so formed, and that adjustments will be made kin accordance with the exigencies of all cases, and, furthermore, that all of the parts will be originally made to correspond with the strength required of them, as Well as to the demands under which they may be put, as length, &c.

I claiml. The combination, with the draft-means, and its vertical extension, of the main beam or means drawn upon, the said vertical extension being pivotally connected to the latter means.

2. The combination, with the main tongue or beam, of the lateral beam and the Vertical extension attached to the inner end of the latter, the said vertical extension being pivotally connected with the main tongue or beam.

3. The combination, with the main tongue or beam, of the lateral beam,and the vertical extension attached to the inner end of the latter and provided on its lower portion with a horizontal extension, the said vertical extension being pivotally connected with the main tongue or beam.

4. The combination, with the main tongue or beam, of the lateral beam and the vertical extension attached to the inner end of the latter, the said vertical extension pivotally and adj ustably connected with the main tongue or beam.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

JOHN J. LARSON. Witnesses:
