LAIRD J. JACKSON, OF PITTSBURG, PENNSYLVANIA, ASSIGNOR T0 ROBERT M. MILLER, OF PITTSBURG, PENNSYLVANIA.

EQUALIZING DRAFT-GEARING;

1'0 all who-m it may concern:

Be it known that I, LAIRD J. JACKSON, a citizen of the United States, residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Equalizing Draft-Gearing, of which the following is a specification, reference being had therein to the accompanying drawing.

My invention consists of an improvement in equalizing draft gearing for wagons, etc., and particularly for heavy draft wagons.

It has for its objects to provide means for hitching a team to the wagon in such a manner that the pull will be directly against the front axle by equalizing mechanism through which the strain is transmitted so that the pull will be forward and also upward, and whereby a pull toward the right or left will throw the axle in the proper direction transversely of the wagon bed toward the right or left for turning in a corresponding direction.

The invention embraces the construction illustrated and hereinafter described and its parts made and adapted to operate in the manner hereinafter described.

In the drawings :Figure 1 is a plan view of the gearing. Fig. 2 is a vertical longitudinal sectional view of the front running gear showing the construction. Fig. 3 is an enlarged cross section on the line III. III. of Fig. 1. Fig. 4 is a side view of the separable supporting clip for the equalizing bar. Fig. 5 is an enlarged sectional View on the line V. V. of Fig. 1.

2 is the front axle of the wagon upon which its body is supported by the usual springs and having the customary tongue 3 provided with the double tree 4.

5 is an equalizing bar, preferably of hollow tubing or pipe, suspended from the double tree 4 by the separable clips a consisting of two

co-acting parts

6 and 7.

Each of said parts is hollowed out transversely across its middle inner portion and the two parts embrace bar 5 and are secured thereto and together by transverse bolt 8, one of said clips a being located at each end of the bar 5 in proper position for attachment of the swingle trees 9, 9.

Each

side

6, 7, of each clip has an upwardly extending eye portion 10, 11, respectively, which form together a split ring for easy connection with the eye 12 of the Specification of Letters Patent.

Application filed July 26, 1909.

double tree 4, as will be readily understood. Forward side 7 of each clip is provided with a hook 13 for connection with the link 14 of swingle tree 9, said hook having a hookand-eye connection with a corresponding holding extension 16 of side 6. By this construction, when the clip a is assembled and connected with the bar 5 by bolt 8 and attached to the other parts, it forms a strong rigid connection and is easily and quickly assembled and taken apart.

The axle 2 is provided at each end with a clip 17 having an eye 18 for connection of the

diagonal chains

19, 19, the clips being cut out at 20 for clearance of the axle spring clips 21 and clip 17 is secured to the axle by U bolt 22. Clip 17 has a bolt hole at one side and an elongated slot 23 at the other side so as to admit of attachment to axles of different sizes by different sized bolts 22.

24 is a spanner located about midway between the axle 2 and the equalizing bar 5 and centrally of the width of the lateral space, consisting of a substantially flat piece of metal having the divergently arranged

horns

25, 25, at back and 26, 26, at front. Each of said horns is provided at its extremity with link openings 27 having longitudinal and transverse clearance spaces as clearly shown, and preferably hollowed and rounded to fit the links, whereby the links of chains 19 and oppositely arranged diagonally disposed similar chains 28 are connected to the spanner in the manner shown. The spanner is preferably provided at its middle portion with a similar link opening 29 for attachment of the end of a chain for hitching a third or middle horse.

Chains 28 are connected with eyes 28' at the ends of bolts 8 which secure clips a to equalizing bar 5, preferably with intervening draft springs 30 of well known construction, and in assembling the parts the chains are drawn up tight so that they, with the spanner, provide a fairly stiff connecting structure. By this means, when the power of the team is exerted through the swingle trees and their connections 14, they pull forwardly on the lower ends of clips (0 and draw the equalizing bar 5 forwardly, the

' split eyes 1011 forming a fulcrum connection with the eye 12 of double tree 4, the pull being exerted through the equalizing bar 5, chains 28, spanner 24 and chains 19 to each end of the axle 2. Thus a back thrust is exerted on the double tree 4, relieving it and its connection with the tongue of the usual pulling strain.

As shown, the plane of

chains

28, 19 and spanner 2% is upwardly and forwardly and the connections 14 of the swingle trees with the lower ends of clips a being low, the pull by the team is also upwardly and forwardly. This is of great advantage, especially on rough or steep roads, and utilizes the horse power to the best advantage.

The entire structure provides an approximately stiff tension frame connection between the swingle tree connections and the axle, so that turning strains or pulls are directly applied to one end or the other of the axle, avoiding the usual strains through the tongue and the front collar connections therewith.

lVhat I claim is:

1. Equalizing draft gearing consisting of an equalizing bar, a centrally located spanner, flexible connections leading from said spanner to the terminals of the equalizing bar and to divergent points of attachment of the running gear of a vehicle, and means for connecting the equalizing bar with pulling apparatus.

2. Equalizing draft gearing consisting of an equalizing bar, a centrally located spanner, flexible connections leading from said spanner to the terminals of the equalizing bar and to divergent points of attachment of the running gear of a vehicle, supporting clips for the equalizing bar secured to each end thereof, a double tree having carrying means therefor engaging said clips, and pulling apparatus connected with the clips.

3. The combination with the axle of a vehicle, of an equalizing bar located forward and upward from the axle, means connecting the equalizing bar with the pulling apparatus, a spanner, and means connected with the terminals of the axle and equalizing bar respectively and to said spanner.

l. In equalizing draft gearing, the combination with the axle of a vehicle, of an equalizing bar, a centrally arranged spanner intermediate between the axle and the equalizing bar, means connecting the spanner with each end of the axle and equalizing bar respectively, and means for connecting the equalizing bar with pulling apparatus.

5. In equalizing draft gearing, the combination with the axle of a vehicle and a double tree, of an equalizing bar, means con necting the equalizing bar with each end of the axle, a clip supported from each end of the double tree engaging the ends of the equalizing bar, said clip having means for connection with pulling apparatus.

6. The combination with an axle and equalizing bar, of an intervening spanner provided with divergently arranged terminals, and connecting elements leading from the ends of the axle and equalizing bar respectively and having adjustable connection with the terminals of said spanner.

7. The combination with an axle and equalizing bar, of an intervening spanner provided with divergently arranged terminals, connecting elements leading from the ends of the axle and equalizing bar respectively and having adjustable connections with the terminals of said spanner, and means for supporting the equalizing bar and for connecting it with pulling apparatus.

8. The combination with the supporting bar of a draft gear, of a separable two-part clip providing a supporting eye, and embracing the sides of the equalizing bar, one of said sides having a depending portion engaging the other side and adapted to make connection with the swingle tree, with means for securing said clip to the equalizing bar.

In testimony whereof I aflix my signature in presence of two witnesses.
