DRAFT-EQUALIZER.-

Specification of Letters Patent.

Patented Nov. 19, 1912.

Application led May 25, 1912. Serial No. 699,678.

To alljwhom 'it may concern:

Be it known that I, Dnvm W. EMERICK, a citizen of the United States, residing at Kilgore, in the county of Cherry and State of Nebraska, have invented certain new and useful Improvements in Draft-Equalizers, of which the followingwis a specification, reference being had therein to the accompanying drawing.

This invention relates to draft equalizers and has special reference to a device of this character arranged for an easy change of a two-horse to a three-horse equalizer.

The principal object of the invention is to improve, and simplify the general construction of devices of this character.

With the above and other objects in view, the invention'consists in general of certain novel constructions, combinations and arrangements of parts as will be hereinafter fully described, illustrated in the accompanying drawings, and specifically claimed.

In the accompanying drawings, like characters of reference indicate like parts in the several views, and Figure 1 is a plan view of the device partly broken away showing the same in use as a two-horse equalizer. Fig. 2 is a similar view showing the device used as a three-horse equalizer. Fig. 3 is a transverse section through the wagon tongue when the device is in position for use as a three-horse equalizer. Fig. 4 is a detail view of a supporting arm or brace used in connection with the device. Fig. 5 is a detail perspective of a certain strap used in making connection with the axle of the wagon. Fig. 6 is a plan view of an equalizer bar. Fig. 7 is an edge view thereof.

. In the present embodiment of the invention there is provided the usual wagon axle 10 whereto is attached a pole or tongue 11 the same being properly braced by braces 12. At a point somewhat in advance of these braces there is provided a laterally projecting arm 13 and this arm is securely iiXed to the tongue at its inner end and is provided at the inner end with an opening registering with an opening in the tongue as indicated at 14. Adjacent the outer end of the arm is provided a hook 15 and between the outer and innerend there is a second opening 16. Surrounding the axle 10 is a. clip which consist-s of a strip of met-al bent to conform to the shape of the aXle and having its bottom part tapered to form a hook. The body of the strip is here indicated at 17 and the hooked end at 18. This strip has its front and rear vertical `portions provided with opposed openings 19 wherethrough pass suitable bolts 20 which serve to hold the strip in position. Extending from the hook 18 to the hook 15 is a chain 21 which serves to bracejthe outer end ofthe arm 13 and it is to be noted that this chain extends diagonally across the tongue as can be clearly seen by reference to Figs. 1 and 2. The tongue is provided with the usual hammer strap 22 but in the present instance this strap is pivotally mounted on the tongue as at 23 and is provided with an opening 24: adjacent its end and an intermediate opening 25 which, when the strap is swung over the tongue will register with the openings 14.

There is furthermore provided an equalizer bar 26 having a centrally disposed opening 27 and a second opening 28. This equalizer bar is provided with hooks 29 adjacent each end and the position of the opening 28 is such that the distance from one of the hooks 29 is twice as great as that from the other hook 29. These hooks are used when the device is in use as a two-horse equalizer for the attachment of swingle trees 30, while when the device is used as a threehorse equalizer the hook nearest the opening 28 is used for the attachment of a double tree 31 whereto may be attached the swingle tree 32. When in use as a two-horse equalizer a bolt 33 is passed through the openings 27, 25, and 14 so that the swingle trees 30 will be evenly spaced on both sides o f the pole 11.

Then in use as a three-horse equalizer the equalizer bar is moved to bring the opening 28 in alinement with the opening 16 and the bolt 33 is passed through these openings and through the opening 24e in the end of the hammer strap which is swung over to the position shown in Fig. 2 to permit such action.

There has thus been provided a simple and efficient device of the kind described, and for the purpose specified.

Having thus described the invention, what is claimed as new, is

In a draft equalizer, an axle, a pole rigidly attaehed to said aXle and extending forwardiy therefrom, said pole being provided with an opening therethrough, an arm eX- tending laterally from the pole having an opening registering with the opening in the pole, a second opening spaced from the pole,

centrally-disposed opening, tree attaching;

al clip secured to said axle on the side oppol means adjacent the ends of said equalizer 15 site that from which the arm extends, a a bar, the distance between the second openchain connecting the clip and the outer end ing in the equalizer bar being twice as great of said arm, a hammer strap having its rear from one of said tree-attaching means as end pivotally connected to said pole between from the other thereof, and a bolt adapted the axle and the opening in the pole7 said to pass through selective one of said open- 20 hammer strap being provided with an ope1iings.

ing adapted for registration with the open- In testimony whereof I hereunto affix my ing in the pole, and a second opening adjasignature in presence of two witnesses.

cent its end adapted for registration with DAVID W EMERICK the opening in the arm, an equalizer bar provided with a centrally disposed opening, and a second opening in spaced relation to the Witnesses J. C. SNYDER,
