Chicago, in the'county of Cook and State' -ot' Illinois," have invented Improvements in "lfiocomotives,- of specification. I This invention construction"affording relative flexibility of the*supporting"wheels and-axles so to" readily follow uneven track. 1 f

In locomotives ofthe usual type; the

axles*are sup'por'ted'in suitable axle boxes ""mounted' on vertically disposed guides on' the locomotive frame and having'springs interposed'b etween each axle box andthe frame;

Such a construction allows theend of the axle to move vertically-a. limited distance dependin upon'the resiliency of the springs, In. the present invention,- I provide means at: fording greater fiexibilityot movement of the axlecoinprisingan equalizing device i n. which the opposite ends of a single axle are each connected to a longitudinally disposed bar pivotally 1 mounted on the frame and movable in a vertical plane. The free ends of these bars are connected by suitable links to a torsion bar extending transversely of Q the frame and pivoted thereon. By means of this arrangement the axle is permitted to swing in a vertical plane independent of the resiliency of the springs.

The invention consists in the combination,

construction and arrangement of parts as will hereinafter be described 1 in connection with the accompanying drawings and, more particularly defined in the appended claims. In the drawings, a Figure 1 is a fragmentary top plan view of a locomotive showing one of the axles thereof provided with an equalizing device con structed in accordance with my invention.

. Fig. 2 is a side view of a locomotive with portionsof the supporting wheel-and one side of the frame broken away to show the construction and arrangement of the equal izing device, 1

In the drawings, one. embodiment of my invention is illustrated, as applied to a 1000- motive frame having side plates 2, 2, an axle 3 and supporting wheels 4;, 4. Suitable j ournal boxes 5, 5, are mounted adjacent opposite ends of the axles and are movable yer- Wmnmivt' 'WJ SLoA-Nn, a citizen ofthe United States, residing at.

which the following is a "relates "to improve ments in locomotives or trucksand hasfor its pr nclp-al ob ect to provide an improved any suitable construction; The. equalizing.

device comprises a. pair of longitudinally disposed supporting bars 8 and 9 pivotally no I l u ntcd on opposite sidesof the 'locomotive' frame on pivotal joints 8? and 9 respectiveshow'n. tiprings 10, 10, whichma'y be ofthe usual helical type or its equivalent, are'interposed between each or the axle boxes .5, 5,

I ly. {One of the'supporting bars 8 is prefen. i

ably shorterthan the 'supportin g bar 9 "as f and stirrups 8 and'9 located 'ir termediate I the ends of supportingbars' Sand 9 respect1-vely Tn th-epreferred form shown, each of said st1rrups PlOjBClZS downwardly and,

outwardly into supportingfposition above its respectivespringl'tl, which is movably mounted between the {guide plates 6, of the pedestal '7 as already described] This ar:

' magement, ofl'the stirrup's and springs gmay bevaried,'a sdesired,"*depending upon the i type of springs employec'h-and variations in design of the frame andaxl'e. The free ends of supporting bars 8 and 9 are operatively connected by means; of a transversely dis- POSQtltOISlOIL bar 11. The supporting bar 8, which is the shorter ofthe'two supporting bars, is connected tov a crank arm 12 by means of a pivotal link-13. Said arm 12is rigidly mounted on i the'torsion bar '11 and extends longitudinally therefrom toward the axle 3 An arm 14: is rigidly mounted on the oposite end of the torsion member 11 and extends longitudinally in a direction opposed to the arm 12. "Arm 9 is pivotally connected to the arm- 14 by a pivotal link 15. The arrangement is such that i any: pivotal movement of one of the supporting arms such as the arm 8,.in one direction will cause rotation of the torsion member 11 and a" corresponding movement of arm 9 in the opposite direction. Any verticaldisplacement of one end of the axle willtherefore cause corresponding displacement of the oppo-' site end of the axle in a reversedirection, It will thus be seen that when the locomotive is moving over uneven track, the axle is free to swing a limited distance in a transverse plane irrespective of theresiliencyot the springs.

In applying my invention to a locomotive of the two axle type, it is preferable to mount one of the axles in the usual manner,

that is to say, without an equalizing device,

' wide range of flexibility with respect to the frame and the one stabilizing axle connected therewith. By means of'this arrangement, the load is maintained evenly on all of the supporting wheels while moving over uneven track. In a similar manner, when applied to a three axle locomotive, two 'of the axles only are provided with transverse equalizing devices.

Although I have shown and described one form in which my invention may be embodied, it will be understood that many other means may be employed for accomplishing the same results, without departing from the spirit and scope of my invention. I do not therefore wish to be understood as limiting myself to the specific construction or use illustrated herein excepting as specifically limited in the appended claims.

I claim as my invention:

1. In a car, aframe, an axle movable in a substantially vertical plane respective to said frame, and an equalizing device com-- prising a pair oflongitudinally extending bars each pivotally mounted on the frame adjacent opposite ends of said axle in sup porting engagement therewith, and means operatively connecting said bars together, including a transversely disposed. torsion member pivotally mounted on the frame.

2. In a car, a frame, an axle movable in a substantially vertical plane respective to said frame, and an equalizingv device comprising a pair of longitudinally extending bars each pivotally mounted on the frame adjacent opposite ends of said axle in supporting engagement therewith, a transversely disposed torsion member pivotally mounted on the frame, and means coaoting between'e'ach of said bars and said torsion member whereby vertical movement of oneend of sald axle in one dlrection is trans mitted through the medium of said torsion member and said bars and causes a corresponding movement of the other end of said ing bars each pivotailly mounted-on the frame adjacent opposite ends of said axle in supporting engagement therewith, a transversely disposed torsion member rotatably mounted on said frame, a longitudi nally disposed rigid arm on said, torsion member extending in one direction and hav-- ing operative connection with one of said bars, and an oppositely disposed arm having operative connection with the other of said bars,

Signed at Chicago, in the county of Cook and State of Illinois,.this twenty-first day of January, 1922. J
