BERT VVASIIAM, OF PRYORGREEK, INDIAN TERRITORY.

DRAFT-EQUALIZER.

SPECIFICATION forming part of Letters Patent No. 718,180, dated January 13, 1903.

Application filed June 16, 1902.

To aZZ whom it may concern:

Be it known that I, BERT WASHAM, a citizen of the United States, residing at Pryorcreek, in the Cherokee Nation, Indian Territory, have invented certain new and useful Improvements in Draft-Equalizers; and I do declare the following to be a full, clear, and exact description of the inventionfsuch as will enable others skilled in the art to which it appertains to make and use the same.

The invention relates to a draft-equalizer.

The object of the invention is to provide a draft-equalizer which shall be simple of construction, durable in use, comparatively inexpensive of production, and the parts of which are so arranged that four horses may draw abreast, three being located upon one side of the tongue or pole and one upon the opposite side, the one equalizing the pull of the three others.

With this and other objects in view the invention consists of certain novel features of construction, combination, and arrangement of parts, which will be hereinafter more fully described, and particularly pointed out in the appended claim.

In the accompanying drawings, Figure 1 is a top plan view of my improved equalizer, and Fig. 2 is a front view.

In the drawings, l denotes the tongue or pole of a vehicle or agricultural machine, and 2 denotes a short lever pivotally connected by a bolt 3 to the rear end of the tongue or pole. This lever 2 has a plurality ofopenings for the pivot 3, whereby it may be shifted on the latter as may be necessary;

4 denotes the evener-lever,pivoted by a bolt 5' to the tongue or pole in advance of the lever 2 and pivoted near one end, whereby one end of the leyer v5 projects laterally a greater distance from the tongue or pole than the other end 6 of said lever.

7 and 8 denote doubletrees, the latter of which is pivoted to the long end 5 of the lever by a bolt 9, and the former of which is pivotally connected to the short end 6 of the lever by a pivoted crank 10, one end of the crank being pivoted to the short end of the lever, and the other end 11 of the crank being pivoted to the doubletree 7. This doubletree 7, it will be seen, has not only a pivotal connection with the short end of the lever, but,

Serial No. 111,971 (No model.)

owing to the crank, has also a swinging connection.

12 denotes a link connecting one end of the lever 2 with the central portion of the doubletree 7, and 13 denotes a link pivotally connecting the other end of the lever 2 to the long end 5 of the lever 4E.

14: and 15 denote singletrees attached to the doubletree 8,and 16 and 17 denote singletrees attached to the doubletree 7. The singletrees 14, 15, and 16 are, as indicated, located upon one side of the tongue, while the singletree 17 is located upon the opposite side of the tongue.

When the draft-animals are attached to the respective singletrees, three upon one side of the tongue and one upon the opposite side, the draft of the three upon one side of the tongue will be evened or equalized by the draft of the one upon the opposite side of the tongue in the manner common to this class of devices.

From the foregoing description, taken in connection with the accompanying drawings, the construction, mode of operation, and advantages of the invention will be readily understood without requiring an extended explanation.

Various changes in the form, proportion,

and details of construction may be made with-,

in the scope of the invention without departing from the spirit or sacrificing any of the advantages thereof.

It will be observed byreference to Fig. l of the drawings that the doubletrees 7 8 are disposed directly over the evener-lever 4 and that the crank-link 10 is normally parallel with and between the lower side of the doubletree 7 and the upper side of the evenerlever, and this disposition is maintained irrespective of the adjustment of the lever 2 on its pivot 3. Hence the wrists at the ends of the crank, which effects the connections between the same, its doubletree 7, and the evener-lever are prevented from being bent under the stress of the draft, and the intermediate portion of the crank is also kept straight.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-- The combination of a draft tongue, an

I ally connected thereto, and a link 12 connecting the doubletree 7 to the end of lever 2, 0pposite that to which link 13 is connected, substantially as described.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

B. WASHAM.
