T0 @ZZ whom it puny concer-71,.-

Be it known that we, JOHN R. PARKS and JAMES H. DAY, citizens of the United States, residing at l/Vood Lake, in the county of Cherry and State of Nebraska, have invented certain new and useful Improvements in Draft-Equalizers, of which the following is a specification.

This invention embodies an improved draft-equalizer, and the main feature of the invention is comprised in the general simplicity of the construction of the device and the peculiar arrangement of the parts comprising the same, whereby special advantages arise in the practical use thereof.

For a full description of the invention and the merits thereof and also to acquire a knowledge of the details of construction of the means for effecting the result reference is to behad to the following description and accompanying drawings, in whichh Figure 1 is a top plan view of a draft-equalizer embodying the invention. Fig. 2 is a front elevation.

Corresponding and like parts are referred to in the following description and indicated in both the views of the drawings by the same reference characters.

Referring to the drawings, the numeral 1 designates the tongue, and the numeral 2 indicates a transverse equalizing-lever which is pivoted at a point between its ends, as shown at 3, to said tongue `1. The e ualizing-lever 2 is pivotally connected to Jthe tongue by means of a clip 4 or similar part attached to the same, said lever 2 being arranged beneath the tongue to admit of the use of the invention on mowing-machines. `The point of pivotal connection of the lever 2 with the tongue 1 is nearer one end of the lever than the other. A doubletree 5 is connected by a link 6a with one of the outer ends of the lever 2that end which is more remote from the tongue 1. It is designed that the equalizer be of the three-horse type, and a short lever 6 is connected at a point between its ends, as shown at 7, with a link S, which in turn is connected with the short end portion of the lever 2. The link 8 is pivotallypconnected with the parts 2 and 6, and the lever 6 is pivoted at its inner end to a bracket 9, attached to the tongue 1, a swingletree 10 being connected to the outer end of the short lever 6 by means of a link 11. The bracket 9 is of a peculiar form, being so attached tothe tongue 1 as to place the draft below the same, or, in other words, the disposition of the bracket 9 is such that the parts 6 and 10 with adjacent connections are arranged below the plane of the tongue 1 and in the plane in which the equaliZing-lever 2 is located. The bracket 9 is composed of superposed bracket-irons, (indicated at 9a and 91),) said irons being of approXimately U form in top plan view. The curved ends of the irons 9a and 9b are disposed above and below, respectively, the end of the short lever 6, to which they are pivotally connected. Each of the irons 9a and 9b is formed at its spaced extremities with upwardly-projecting extensions 12, and these extensions are connected together by means of U-shaped clamps 13. The clamps 13 receive the tongue 1, and the ends of the clamps pass through the extensions 12 of the bracketirons above described, suitable nuts being screwed on the ends of said clamps to hold the same in secured positions, The clamps 13 not only connect the bracket-irons 92L and 9b together, but said clamps also secure the bracket-iron to the tongue.

The manner of attaching the bracket-irons has particular advantage in that the bracket is arranged below the plane of the tongue, and, further, the attaching means by which the bracket is held in place does not weaken the tongue at all, as the clamps 13 do not necessitate the provision of openings or the like such as ordinarily provided in securing the parts of equalizing devices of this class.

The advantages of the invention will be obvious from the foregoing, and the same are therefore not speciically set forth.

Having thus described the invention, what is claimed as new is- In a draft-equalizer, the combination of a tongue, a transverse equalizing-lever pivoted at its ends to the tongue, a bracket projecting laterally from the tongue in advance of the equaliZing-lever, said bracket being composed of upper and lower U-shaped bracketirons, U-shaped clamps receiving the tongue and connecting the bracket-irons together and securing the same to the tongue, a short lever connected at its inner end with the IOO bracket and having said end received be- In testimony whereof We affix our signete tween the bracket irons, a link connecting tures n presence of tWo Witnesses.
