IMPROVEMENT IN DRAFT-EQUALIZERS.
Specification forming part of Letters Patent No. 222,240, dated December 2, 1879 application filed i August 2, 1879. I
To all 'whom it may concem Be it known that I, WM. T. BURRoWs, of Nashua, in the county of Chickasaw and State of Iowa, have invented certain new and useful Improvements in Draft-Equalizers; and I do hereby declare that the following is a full, clear, and exact descriptionof the construction and operation of the same, reference ,beinghad to the annexed drawings, making a part of this specification, and to the letters and figures of referencemarked thereon.
Figure 1 is a plan view of a draft-equalizer embodying the improvemen ts in my invention,
i W and Fig. 2 is a Vertical elevation and a plan View of the double Shea-ve employed theren.
This iuvention relates to draft-equaliz'ers which are employed in connection with plows, harvesters, and-the like.
My improvement consists in the construction and arrangement of certain parts, as will be hereinafter described and claimed.
In the drawings7 A represents the tongue of the machine, which is to be dra-wn by horses. B designates a bar, to each end of which a single-tree is connected by means of the usual clevis, and this bar is connected with chain c by the pivoted clevis d. This chain passes roundand is secured to a wheel, d', which is arranged upon thetong'ue, as shown, and another chain, c', secured to said wheel, connects With a rod, e.
F is a bar or arm pivoted to the side of the tongue between lugs-o o, and the said rod e is chains c is secured.
clevis, also passes through like parts of a clevis, h, having a hoolz, m, to which the sin- In this instance, also, a rod, n, connects with the rod e at the end where the chain is linked thereto, and the other end of this rod n is bent down so as to be passed through the end of-bar F, and also through the lngs 0 0 of the metal plate p, which is secured to the side of the tongue. I
It will be seen that the upper section of the device which l have called a wheel is, in fact, not similar to the lower part and not a true wheel, since its periphery from a given point gradually approaches its center until it terminates at o, where one end ot' one of the This construction aids in equalizing` the draft, the operation being simply upon the principle of the lever. i
What I claim is i In a draft-equalizer, the arm F, pivoted to the tongue A between the lugs o 0, in combination with the rods e and n, connected as described, the chains 0 c', 'and wheel having" grom-'es (12 e13, the clevis d, and bar B, as and 'of two witnesses.
