'Yin-.He sn-vailvfi 'nide piates il are preferably secured tn the Yvltlcal websvoi the truck mister i0 by rivets 12, incnted both above and helkyw the hofizmiiai web of the said bolster. The said plates 11 directly` take the wear incidc'n to vertical movements and endwise thrusting :now-mente of the bol.- stervin respect u the bolster mumns, and for ihis reason, :i1-v heiter than laterally spaced guide. lugs or stops on the bnster wnont the connecing pute to take the direct wem'. Except for this latter noted reason, the inner 1mi outer colnmn engaging Ezrefeably this truck boiser is in the form.

'il l.,

guide lugs on tin bolster might be completely separated or `:.li\":1lually formed.

` It is here important io malte the following observations: The bolster columns 3 are formed with bolster guiding surfaces 3* 'for engagement with the guide plates 11, which terminate below the upper compression mem bers of the coperating side frames a disv tance greater than the vertical dimensions of the said guide plates and of tbe track bolster, and said bolster columns above these bolster guidingr surfaces are spread or separated at 3" to an increased extent so that tbe bolster, when raised to an extreme position, may he removed endwise from the truck side frames, through clearance passages 14, without requiring removal from tbe truck bolster of the column engaging plates or lugs. This construction also permits tbe upper compression members of the side frames to be cast integral with the cast bod)- portions of saidside frames. It will be also noted that tbe bolster guiding surfaces of said bolster columns are set farther apart than the extreme lower portions of said columns so that a track bolster of as great, or even greater, extent, than the distance between the vertical flanges of the column base plates 6, may be emplo'fed. The springs 9 iyill be entirel relieved from tension when the truck olster is raised into position to` be moved endwise from the truck side frames through the widened clearance paages M.

The truck bolster 10 has rigidly secured 1 to the end portions thereof roller bearing plates 15, located in the upper channels thereof, and or'medwitl. a multiplicity of roller seats extended longitudinallyof the truck side frames and supporting lateral motion bearing rollers 16,t the central members of which, 'as shown are in the center planes of the corresponding truck side frames. Uoon the rollers 16 is mounted a so-called floating or intermediate bearing plate 17, which for engagement with tle roller.` 16 has, in its undei surface, roller seats corresponding to the roller seats in the plates 15, exce t that they are reversed or turned upside own. The bearing plates 15 and 1T and the'inter osed rollers l all'ox-d the lateral motion d) presently to be described. Otherwise stated. these lateral motion devices permit lateral motion of the car body relative to the truck. ll, should be here stated that. the roller bearing seats of the plates 15 and 17 are concave (the word concave being here :ised vin u broad sense) but their conoavities may be formed either by a curve or direrging straight lines or planes, the well known function of which is to maintain tbe said plates 17 in intermediate position in respect to tte plates 15.

evices for permitting. endwise movements of the ear body bolster The car body bolster 1S which, :is shown, has rigidly `ecured to its end portions .lcpending)r bcariuglegs It?, arranged in pairs and arranged to embrace the upper compression members ot the trucl: ide t1-unies with sufficient clearance to permit the required lateral motion of the car body in respect to the truck. As slnm'n,`tl1ese pairs of bearing legs 19 are cast integral with :i ric plate E20, whichz in turn, is rigidly secured Lo tb:- body bolster bv means of rivets. 'l'lie lower ends of these bearing legs 1b rest upon and move with upper roller bearing plates 2l, between which and the intermediate bearing plate 11", side hearing rollers 2:2 are interv posed. Preferably the upper roller bearing plates' 21 are detachable from the bearing legs 19 but are intel-locked thereto by lugs 23 on the said plates 2l, which engage. notchesor seats in the lower portions of .said beziring legs. The rollers extend approxi mately at. right angles to the rollers 16 and are arranged to work in grooved flat-need seats formed in the said plates lt'and 2l, which seats, in plan, are curved on the arc of imaginary circles struck from the axis of the pivotal connection between tlie'truck and body bolster., Preferably also the upper or side bearing rollers 2. :irc arranged in two series with the rollers of the inner Series axially a'lincd with the rollers of the outer series and with all of the said side bearing rollers propel-l",Y spaced b v a retaining cage 24, of suitable construction, such for instance as that disclosed and claimed in my o-pcndin;: application, S. X. 536.085. tiled ot' inte January 3rd, 1910. and entitled Improved roller bearing. The roller sini-- ing cage is desirable in order lo keep the side bearinlgr rollers from bnnching und to keep the entire lot of rollers :l2 propel-lj,v centered and positioned in respect to the bearing plates between which they work. The said .side bearing rollers are preferubi)v arranged in two series with the inner and outer rollers axially alined. because the relatively short rollersl are better adapted, when.cylindrical, to worl: on a slight. are of u circle, than are rollers of much greater length.

The central.portions' of the trui-k und body holsters are pivoteilly'connected bv u suitable center coupling, which :illords the proper pivotal connection between the said parts and permits the required limited lateral movements of the car bod)Y in respect to tbe truck and vice versa and allowsl all' the weight of the loud to be delivered from the body holsters to the truck bolster und t e truck side frames through the roller si e bearings and lateral motion devices. Pre crably this center connection is subs.' .mtial of the form disclosed in mv .sind prior pate No. 863,012, of flute Auger# 13th. i907, n

comprises center plates' and 26, rigidly connected respectively to the body bolster 1H and tbe truck bolster 10. The said plates 25 and Q6 have telesooping or'interlocking 5 hubs 'of unequal size, the lmliof the lower plate 26 being considerably larger than the ub of the upper. plate and being also, as shown, of rectangular form, while the hub 0f the appel-,plate is of circular form. The two plates 25 and 2G are connected by a king pin '27 closely fitted in the hub of the upper plate and working in zin-elongated slot 28 in the lower plate. i

It should be noted that the roller bearing devices are located in the clearance passages but are formed inthe truck side frames immediatcly below the upper compression members of the same and that they, thereford normally hold the truck bolster down so that it cannot move, upward in alinem'ent of these clearance pxssages.

What I claim is:
