MONS P. LOMEN, OF MAYVILLE, DAKOTA TERRITORY.

DRAFT-EQUALIZER.

SPECIFICATION forming part of Letters Patent No. 372,859, dated 1 \Tovember 8, 1887.

Application filed April 14, 1887. Serial No. 234,748. (No model.)

To a. whom it may concern:

Be it known that I, MoNs P. LoMEN, of the city of Mayville, in the county of Traill and Territory of Dakota; haveinvented a new and useful Improvement in Four Horse Draft- Equalizers, of which I do'hereby declare that the following is a full, clear, and exact description, which will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

The nature of my invention consists in the novel arrangement and combination of doubletrees and equalizing-bars, so as to equalize the draft of four horses when working abreast on harvesters and binders or other machines as they are needed.

In the accompanying drawings, Figure 1 is a top elevation of a reaper and my improved equalizer attached. Fig. 2 is a plan view of my draft-equalizer as if attached to a harvester and binder.

Like letters refer to corresponding parts in the several figures.

. Referring to the drawings, A designates the tongue or pole of the harvester or other machine, or the beam of a gang-plow.

B is a rigid bar, one end of which is securely fastened to and on top of the tongue A.

D and G are equalizingbars equal in length, D overlapping U and at one end bolted to it, so that the distance from c to fis one-third of the length of either D or C. To the other end of D and on its top side is fastened, with clevis and pin, at f, an ordinary doubletree, E, with singletrees a and a attached. On the top side and at the farther end of O is placed a block at f, or else this end of equalizing-bar O is made double in thickness, so that its top is on a level with equalizing-bar D. To C at f and on its top side, where it is thus made double in thickness, is fastened, by clevis and pin, an ordinary doubletree, E, with its singletrees a and a attached. Equalizing-bar 0 over- I as to play upon it at b.

laps rigid bar B several inches and is so bolted Thus both equalizing bars,with their doubletrees attached,play upon gle trees, plays upon equalizing-bar C where bolted to it at 0. v

e is a draft-iron fastened at the back of equalizing-bar D. This draft-iron is placed on equalizing-bar D a little farther from the tongue of machine than the middle of this bar D is, and to e is hooked a draft-chain, G, the other end of which chain is hooked to the machine-frame at X, Y, or Z, or to some part of the tongue A, as may be found necessary. The use of this draft-chain is to prevent side draft on the machine, and the place of its attachment to the machine will. depend upon the amount of side straiuvfound necessary to be overcome in each case. Draft-iron e is furnished with several adj listing-holes, into either of which the chain may be hooked, according to the relative strength of the horses. The rigid bar B is also provided with adjustingholes for changing the place of attaching to it the equalizing-bar 0 when horses of unequal size are used and require it.

When, as in plowing, the driver wishes the three horses to be on the left of the plow-beam and one at his right hand, he simply turns each of the two doubletrees about face and moves draft-iron e to the back side of equalizing-bar D, and shifts the position of rigid bar B, so that it will project from the left instead of the right side of the tongue or beam.

In construction all bars and doubletrees are made of wood and sufficiently strong to stand the draft of four horses.

\Vhat I claim as new, and desire to secure by Letters Patent, is as follows:

1. The combination of the rigid bar B, project-ing from one side of the tongue, the bar 0, pivoted to bar B and extending outward therefrom, the doubletree E, pivoted to the outer end of bar 0, the bar D, pivoted at one end to the bar 0, near the'outer end of the latter, and

extendinginward over thebarGand the tongue, the doubletree E, pivoted to the opposite end of bar D, and the draft-chain G, attached to bar 0, substantially as shown and described.

end to the bar 0, near the outer end of the latter, and extending inward over the ban (3 and the tongue, said bnr D having the draft iron 6, provided with the series of openings, the donhietree E, pivoted to the free end of bar I), and the draft-chain G, attached to one of the openings in the draft-iron, substantially as shown and described.

In testimony that I claim the foregoing as my own I have hereto affixed my signature, IO in the presence of two witnesses, this 4th (lay of April, A. D. 1887.

MONS P. LOMEN.
