DRAFT-EQUALIZER.

SPECIFICATION forming part of Letters Patent No. 787,703, dated April 18, 1905.

Application iiled July 19,1904. Serial No. 217,184.

To @ZZ whom, it 711,614/ concern.-

applied to a running-gear of a wagon without the necessity of boring holes in the runninggear or permanently attaching any of the parts of the equalizer thereto.

A further object is to provide an equalizer of this class to which one draft-animal may be attached on one side of the wagon-tongue and two draft-animals on the other side and the draft be applied to the running-gear in such a way as to prevent side draft upon the tongue and to apply the draft to the front and back axles of the running-gear.

My invention consists in the construction of the draft-equalizer and in its arrangement and combination with a wagon, as hereinafter more fully set forth, pointed out in my claims, and illustrated in the accompanying drawings, in Which- Figure 1 shows a top or plan view of the complete device applied to a wagon runninggear. The Wagon-wheels are omitted. Fig. 2 shows a central longitudinal sectional View Fig. 3 shows a detail perspective view of the device to be attached to the front end portion of the Wagon running-gear, and Fig. 4: shows a detail rear end view of the central portion of the bolster and axle of the rear portion of a wagon running-gear to illustrate the device for attaching a draft-rod to the rear end of the wagon.

'Referring to the accompanying drawings, I shall first describe those parts of the wagon running-gear to which my attachment is connected.

The numeral 10 indicates the front axle, upon which the bolster 11 is mounted. A king-bolt 12 passes through the center of the axle and bolster, thus pivotally connecting them.

The numeral 13 indicates the wagon-reach, the forward end ofwhich is inserted between the axle 10 and bolster 11 and is held in position by the bolt 12.

The numerall indicates the front hounds of the wagon running gear, to which the tongue 16 is pivoted by the bolt 17.

At the rear end of the wagon is the axle 18, upon which the bolster 19 is mounted. The rear end of the reach 13 passes between the rear axle and the rear bolster 19.

The parts just described constitute the running-gear of the ordinary wagon now in common use.

My attachment comprises an evener-bar 20, having attached to its outer end a swingletree 21. At a point two-thirds of the length of the evenerbar from the end to which the swingletree 21 is attached I have provided a clevis 22, and the evener-bar is supported upon the tongue 16 of the Wagon by means of a supporting-bar 23, one end of which is pivoted to the clevis 22 and the other end is connected by a bolt 24 to the wagon-tongue. This bolt 24 is passed through the wagontongue at the point Where the opening is usually provided for attaching a doubletree and is attached to the clevis 22 by a chain 22. Hence it is not necessary in applying my draft-equalizer to the tongue to bore any openings not usually provided in a Wagon-tongue. At the other end of theevener-bar 2O at a point a slight distance beyond the tonguethat is to say, on the side opposite from the side where the swingletree 21 is placedI have connected the doubletree 25 with the evenerbar20. Attached to the doubletree 25 is a swingletree 26 on the same side of the tongue as the swingletree 21, and on the other end of the doubletree 25 is a swingletree 27 on the opposite side of the tongue. In-this Way one draft-animal stands on one side of the tongue and two draft-animals on the other side, and the draft is equalized at the clevis 22. In this connection it is to be understood that the supporting-bar 23 is not provided for the purpose of applying draft direct to the tongue, but is simply for the purpose of supporting the evener-bar 20.

I have provided a bracket to be mounted on the front end of the reach 13 and held in place by the king-bolt l2. This bracket comprises a fiat bar 28, designed to rest against the under surface of the forward end of the reach. It is provided at its forward end with an opening 29 to receive the king-bolt 12, as shown in Fig. 2. On top of its other end is an angular sleeve 30, through which the reach is passed to thereby retain the bar 30 in line with the reach. On the bottom of the rear end of the bar 28 is an extension 28, projected downwardly, then forwardly, and then upwardly to a point near the central portion of the bar 28, at which point it is attached by means of the rivets 31. Pivoted to the under surface of this downwardly-extending portion 28a is a lever 32, connected to the dow nwardly-extend ed portion by the pin 33.

The numeral 34 indicates a draft-rod attached at its forward end to the clevis 22 and at its rear end to the central portion of the lever 32 by means of the pin 35. At the outer end of the lever 32 I have attached a draft-rod 36, and this draft-rod is extended rearwardly and attached to a bracket at the rear of the rear axle. This latter bracket comprises a block 37, through which the rear end of the rod 36 is passed, and said rod is held to the block by means of the nuts 38. The said block rests against the rear faces of the axle 18 and the bolster 19 and is held in position on the reach 13 by means of the metal loop 39, secured by the bolts 40 to the block 37.

In applying an improved draft-equalizer to the ordinary wagon running-gear I connect the supportingbar 23 with the tongue by means of the bolt 24, which bolt is passed through the opening ordinarily provided in a tongue for attaching a doubletree. I connect the evener-bar with the supporting-bar 23 by the chain 22a and then connect the bar 28 with the front end of the reach by first removing the king-bolt 12, then passing the reach through the loop 30, and then placing the reach and the bar 28 between the axle 10 and the bolster 11, and then inserting the king-bolt 12 through the reach and through the opening 29. I then place the block 37 against the rear of the axle 18 and bolster 19. The draft-rod 34 may thenbe connected with the lever 32 and the clevis 22, and the draftrod 36 is then connected with the outer end of the lever' 32, passed between the axle 18 and the bolster 19, through the block 37, and the nuts 38 are then placed on its end. In this way all of the draft applied tothe clevis 22 is transmitted to the lever 32. My object in having this lever some distance below the reach 13 is so that it will not interfere with the hounds of the wagon or With the front axle. The draft which is applied through the draft-rod 34 to the lever is distributed upon the king-bolt 12 through the bar 28 and upon the block 37 through the draft-rod 36 because the draft-rod 34 is attached to the center of the said lever. The draft that is applied to the block 37 is transmitted to the line with each other when the vehicle is be-` ing advanced, for the action of the draft applied to the front axle will be the .same as that applied to the rear axle.

Having thus described my invention, what I claim, and desireto secure by Letters Patent of the United States therefor, is
