'from the fpodreis or Seats a3, but when the I j.

parte arein the positions Shown in the sev-- eral News oi the drawings, the side frames will beseeurely united to the transom in `such manner as to have, individually, af'pivotal or rocking movement with respect thereto.

By reference more particularly to Fig. 2 of the drawings it )vill be seen that the side frames have the openings so disposed therein that these frames are reve ihle and, hence, if any excessive Wear occurs, for example, at the upper portion of the central opening 0 the side frame can be readily rcmoved and reversed so that the part `ahich before was the top of the side frame will become the bottoni; and this reversibility of the side frames is further advantageous becauseit avoids all danger of any mistake in the proper attachment of the side frames in position, as the side frames can be used upon either side of the truck.

The main portion of the transom l5 is chambered or open to a sutlicient extent to admit the bolster D and to receive the springs E and the spring seats or blocks lf Whereon these sprinois are mounted. The springblocks l1" are shown as supported by the stirrups or straps-G which are U-shaped and set between the side Walls L of the transom B and hat;x their upper ends turned outwardly and secured to the top of the side walls or bars b, as `shovvn in Fig. l. The bolster D may be of any suitable or approved construction and will be lfurnished upon its upper surface with suitable side and center bearing blocks, as Well understood by those familiar with this class of devices.

Adjacent their ends the side iraines il are formed with flanges a* Within Which are the openings to receive the j ournal boxes H and the retaining `rings or keepers K, Whereby these journal boxes are held in engagement with the side frames. The journal boxes ll are fitted interiorly with suitable bearings for the journals m of the axles M, but the details of these journal boxes need not be more fully described, as such boxes will be included in a separatey application for Letters Patent. ln the preferred einbodiment of my invention each of the jour nal boxes H is of a general spherical shape and each journal box is retained Within its appropriate opening at the end of the side frame by means ofthe retaining rings or keepers l. Theilteepers K are preferably formed of two rings, each of which has its exterior surface screw threaded to engage the correspondingly threaded opening at the end of the side frameand each of these rings is preferably formed with a flange or shoulder k at its outer end. The interior surfacesof the two rings K which engage the same journal box H, are reversely curved, so that when the rings are in posiV tion for use, as shown in the drawings, they will accurately tit the spherical surface tageous. of tl e journal box will `insure that at all Locate? the journal box and securely hold itin engagement Vwith the side frame, while at the saine time permitting a swivel or universal movement of the journal box with respect to the side frame. The outer end of each of the retaining rings li is preferably formed with a series. of holes It: adapted to receive a Spanner wrench to permit the rings to be readily screwed to place or Withdrawn.

lt will be understood that While prefer to forni the two rings l removable from the side frame A, it is necessary that but one of said rings be removable, as itWill be obvious that the ,other half of the seat formed thereby may be formed integral vfith the side frame A Without interfering;` with the removal of the spherical journal box H therefrom when desired.

From the foregoing description it will be seen that when the side `frames have been placed upon the cylindrical ends of the bolster B the locking bolts C 'will securely retain the side fra-nies in position, with the inner faces of the side frames abutting against the shoulder o4' of the end portion D of the bolster, When it is desired to malte repairs, as for exai ple, to replace a. Worn or defective wheel, it i.- simply necessary to jacl: up the transom l), Withdraw the locking` bolts C, C from the pockets a3 and slip oli' the side frames. without removing the journal boxes therefrom. lllhen the Wheels are replaced the side frames can then be slippedtoack on to the end portions of the bolster and secured in place as before.

lt `will be seen that inasmuch as the side frames are pivotally connected to the ends .universal joint, any obstruction or depression in the track that inay lift or depress a Wheel vfill cause he adjacent side frame to rock about the end of the tran in a vertical lon udinal plane and will the axle the Wheel lifted or depressed to yield pivotally at appnoxiniately` right angl to the plane of the side frame. ldhen a wheel is thus iifted or depressed and the corresponding` en of the axle is thus raised Vr lowered, the axle also 'has a slight moveinent toward the transverse center of the truck which would tend to cra-mp and strain the parts, except for the pivotal movement allowed by tle journal box. The result is thattfhe strains and shocks incident to the lifting and depression ofthe Wheels under irregularity of the track are very greatlyrelieved, lt is obvious also that even Where Vthe side frames are not pivotally connected,

there be such flexibility between these frames that the employment ofthe spherical boxes and keepers will prove most advan- Wloreover, the pivotal movement ico imam? r times a true alineinent of the bearing with n the journal shall be maintained, so that the or strain upon the danger of excess Wear avoided'.
