GOODMAN WING, OF KAMRAR, IOWA.

DRAFT-EQUALIZER.

SPECIFICATION forming part of Letters Patent No. 480,837, dated August 16, 1892.

Application filed March 12,1892. Serial No. 424,654. (No model.)

To all whom it may concern.-

Be it known that I, GOODMAN W1Nc,a citizen of the United States, residing at Karnrar, in the county of Hamilton and State of Iowa, have invented certain new and useful Improvements in Four-Horse Eveners; and I do hereby declare the following to be a full,'clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form part of this specification.

The object of my invention is to improve the construction of four-horse eveners designed for use on harvesting-machines; and it consists of the several details of construction and combination of parts hereinafter fully set forth in the specification and more particularly pointed out in the claim.

Referring to the drawings, Figure 1 is a perspective view of my improved four horse evener. Fig. 2 is a top view of a slightlymodified construction, and Fig. 3 is a sectional detail View on the line X X of Fig. 2.

Similar letters of reference indicate corresponding parts in each figure of the drawings.

A indicates the pole or tongue of a har- Vester, and B a long evener-bar pivoted near one end on a bolt 1), which passes through a strap or bracket 0 and the tongue A. The bracket 0 is also secured to the tongueA at c. Achain dis connected at one end to the tongue A in rear of the evener or bar B, and at its other end to the long arm of the evener B, and forms a stay to prevent the long arm from being carried too far forward when traction is made on the draft-cable. These stirrups serve as a guide to hold the draft-cable J, preferably of chain or rope of suitable strength, in position on the pulleys, and to keep it from slipping off the end of the evener and falling down when it is relaxed at either end.

In Fig. 2 I have shown a slightlymodified construction of the evener-bar B, in which each of its ends is mortised to form housings for the pulleys E, which are mounted on pins. The pivot bolt or pin 19, which usually passes through the strap and pole to hold the long evener, serves the purpose of a pivot-pin for the pulley E, adjacent to the pole or tongue A.

By thus bringing this pulley directly over the tongue,with its grooved edge proj ecting slightly to one side, the draft-chain from the rear end of the pole is permitted to be drawn parallel to the side of the pole and thereby enable the double eveners to be made shorter and the draft-animals to be brought closer together. In this form of my evener-bar B, I may substitute pins (1 in the extreme ends of the mortises in place of the stirrup D, as shown in Fig. 2, for the purpose of retaining the draft-cable in position on the pulleys E.

F refers to doubletrees, and G to singletrees connected by links g to the doubletrees. A bracket H is secured to the under side of the pole or tongue A near its rear end, and a grooved pulley I is journaled in bearings in the said bracket and tongue. A draft chain or cable J passes round the pulley I, from which the two ends diverge, and after passing round the pulleys E at the ends of the evener-bar B are secured to the doubletrees F at points midway of their length. In this construction of my four-horse evener the draft is on the rear pulley I, which,being journaled to a rigid part of the machine, will consequen tly cause the draft to be direct upon the machine. As all the parts of the evener work loosely, there will be no side or back draft, and as the draft-chain J can work perfectly free around the pulley I, each horse will bear its equal share of the weight to be drawn, whether one pair is in advance of the other pair or not. By having the pulley I on the under side of the pole or tongue A the draft will have a tendency to elevate the front end of the tongue and thereby take the weightfrorn the horses necks. By pivoting the evenerbar B near one of its ends to the pole or tongue the doubletree near the shortest end of the evener or bar will extend across on both sides of the tongue, and consequently one horse of the pair attached to this doubletree will be alone on one side of the pole or tongue and the other horse will be on the opposite side with the pair attached to the doubletree near the longest end of the evener or bar B.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is

In a four-horse evener,a pole or tongue, an

evener-bar pivoted near one of its ends to the to each end of the chain, and two singletrees IO tongue and the other end having a stay to attached to each doubletree, substantially as limit its forward movement, and pulleys jourdescribed.
