UNITED STATES PATENT GEEICE.

SAMUEL A. MASSEY, OF FRANKFORT, KANSAS.

THREE-HORSE EVENER.

SPECIFICATION forming' part of Letters Patent No. 752,087, dated February 16, 1904:.

Application filed October 12, 1903.

To all whom t may concern.:

Be it known that I, SAMUEL A. MAssnr, a citizen of the United States, residing at Frankfort, in the county of Marshall and State of Kansas, have invented certain new and useful Improvements in Three-Horse Eveners, of which the following is a specification.

My invention relates to three-horse eveners, and has for its object to produce a device of this character for use particularly on cultivators and wagons which will perform it function efficiently and reliably. l

A further object is to produce a three-horse evener of simple, strong, durable, and cheap construction.

With these objects in view the invention consists in certain novel and peculiar features of construction and organization, as hereinafter described and claimed, and in order that it may be fully understood reference is to be had to the accompanying drawings, in which- Figure 1 represents a top plan view of a three-horse evener embodying my invention. Fig. 2 represents a vertical section taken on the line II II of Fig. 1.

In said drawings, l designates the tongue of a cultivator, wagon, or equivalent vehicle.

. 2 is a bolt extending vertically through the tongue at a suitable point, and mounted pivotally upon the bolt and at the upper side of the tongue and adapted for horizontal movement is the front evener bar or lever, said bolt extending through the bar or lever so that the arm 3 of the same shall beone-half the length of arm 4. 5 designates a second bolt extending vertically through the tongue and disposed at a suitable distance rearward of bolt 2, and mounted pivotally upon said bolt at the upper side of the tongue is the rear evener bar or lever. Said rear bar or lever is by preference of greater length than the front one and is also pierced by bolt 5 so that its arm 6 shall be half the length of its arm 7 and, furthermore, so that its short and long arms shall project to the same sides of the tongue as the short and long arms, respectively, of the front bar or lever, as shown clearly. At the side of the tongue from which said short arms project is a transversely-extending beam or lever 8, and pivotally unitserian. 176,672. zivomodeia ing the inner end of said beam or lever to the end of arm 3 is a link 9. A link 10 pivotallyT unites the corresponding end of arm 6 with beam or lever 8 at a distance from the point of connection of the latter with link 9 about equal to the length of arm 6. by preference. l1 designates a link providing a swivel connection between the outer end of said beam or lever 8 and the doubletree l2, said doubletree being equipped, as usual, with swingletrees 13. 1li designates a transversely-extending beam or lever at the opposite side of the tongue, and the inner end of said beam or lever is pivotally united to the outer end of arm 4 by link 15. A link 16 pivotally connects the outer end of arm 7 with beam 14 at a distance from the inner end of the latter equal to that portion of beamer lever 8 which lies between links 9 and 10, the relative proportions of beams or levers 8 and 14 being such that their portions outward of the points of connection with links 10 and 16., respectively, are as two to one-that is to say, the outer portion of beam or lever 8 is twice as long as the outer end of beam or lever 14. The outer end of the latter is united by link 17 to the swingletree 18.

From the foregoing it will be apparent that the double leverage given the two horses over the one, because the outer portion of beam or lever 8 is twice as long as the outer portion of beam or lever 14, is counterbalanced through the medium of the front and rear evener bars or levers, the distribution being as follows: It takes one-half of said double leverage to equalize the double leverage which the single horse has through the medium of the front evener bar or lever and the other half of said double leverage to equalize the single-horse double leverage obtained through the rearevener bar or lever. The result is with the center hitch the tongue is carried as straight as though the horse-power on each side was equal.

From the above description, taken in connection with the drawings, it will be apparent that I have produced a three-horse evener which embodies the features of advantage enumerated as desirable in the statement of invention, and while I have illustrated and de- IOO scribed its preferred embodiments it is to be understood that Ireserve the right to make such changes as fall within the principle of construction involved.

Having thus described the invention, what I claim as new, and desire to. secure by Letters Patent, is

The combination with a vehicle having a tongue, of a three-horse evener consisting of a transverse evener-bar pivoted at unequaled distances from its ends, to the tongue; a second transverse evener bar pivoted at unequaled distances Jfrom its ends, to the tongue, and having its long arrn at the same side of the tongue as the corresponding arm of the first-named evener-bar; a transverse beam equipped with a doubletree and accessories at its outer end, and disposed at the same side of the tongue as the short arms of said evenerbars, and connected at its inner end to the front one thereof; a link pivotally uniting the short arm of the rear evener-bar to the said beam outward of the latters point of connection with the front evener-bar; a transverse beam equipped with a swingletree at its outer f end and connected at its inner end to the long arm of the front evener-bar; and a link pivotally uniting the long arm of the rear evenerbar to the last-named beam at the same distance from its inner end as lies between the In testimony whereof I aHiX my signature in the presence of two witnesses.
