ments in Car-Trucks; andA wev dofhereby declare the following'to be a full, clear, and

exact description ofthe inventioin'such as willenable others skilled in the Aart .to which it appertains'to make and use the same. Our invention'relates to improvementsv 'in car trucks, and particularly" to six-wheeled equalized car trucks. To the above-end, generally stated, the invention consists of the novel devicesand combinations ofV devices hereinafter .l described and defined in In the accompanying drawings, which illustrate the invention, like characters l indicate like parts throughout therseveral. views. Referringto the drawings, Figure 1 is a side elevation of the improved car truck with some parts illustrated by means of broken lines; 1. i 2

Fig. 2 is a longitudinal central Section;

Fig. 3 is a fragmentaryplan view-of the improved car. truck, as shown in .'Fig. 1;

The truck frame,as shown, comp.rises1hol low side members 8 and pair of ,transoms 9 integrally formed with vsaid 'side members. The transoms 9 are channel-shaped incross section and horizontal outturned flanges, 1() are integrally formedjwith the upper-edges of the sideslthereof to reinforce the same. By reference to Figs. i6 and 7,` itwill be notedthat the rtransoms 9 are downwardly curved to give the samefa considerable drop. It-will alsobenoted, byj reference toFig. 2,

that the inner walls ofthe transoms .9 are, than 4the outer .walls to considerably lower afford clearance'for acast'ing thatconnects the `members 'of a double bolster,l Ias.will presently appear.` Openings are" provided inthe bottom of thetransoms'for the escape offra-in, snow, iceanddirt; y a v f Suspended from each equalizer v cAR-TRucKl."

The upper ends of thehangeri bolts 24j e1;- tend linto sockets 30j-formed inthebottoms sockets'SO-liold the hanger bolts 24against lateral. movement, but permit 'the' yrequired swinging' movement thereof longitudinally Y' :of the car: truck.. -Thesehanger boltsQLleX- Vtend through.. longitudinally elongatedlslots Y t ed in :the spring c'aps;28V .vandp'elon- .10o of the vequalizer bars" 21 andare pivotally 'Y Y gated slots 33 in the spring bases 27, which permit the insertion ofthe T-heads therethrough. On the bottoms of the spring bases 27, are concave seats 34, which fit onto the' convex upper faces of the T-heads 26 spring bases 27 and spring caps 28, said.

spring bases are securely held, by the Vinterlocking engagement of their seats 34 with Y thefT-heads 26, againstV turning movement with :respect to'thehanger bolts 24.

The Vmembers of a double bolster 35 are mounted, one in each of the channel transoms'9, and are rigidly connected by a heavy H-shaped castingl 36 that is bolted Vtheretlo and has lformed therewith .the lower memlbers-.o1c .a center bearing 37.V The members of thedouble bolster 35 are supported on lateral. motion bearing devices, Veach of which, as shown, comprises three rollers 38 moimted in. seats formed fin a roller bear-l ing plate .orrbase 39.. These roller bearing bases -rest on the bottoms of the transoms 9 close tothe side members 8 and may be secured vagainst lateral movement by .any suitable means. Contours 40 .are formed in `the under faces of the members ofthe bolster 25 to :receive Said rollers 38. By reference to Fig. 7, it will be noted that the ends ofthe bolster 35 terminate short of the inner walls Vof 4the side members 8., in the normal position thereof, and'which walls .aii'ord -stops'to limit the lateral. movement ofsaid bolster.

YTo hold .the members of the bolster 35 within the transoms 9, nut-equipped bolts 41 areextended .through .alined bores inthe side walls of said transoms .and which bolts are. located slightly above the upperfaces of .themembers'oft-he `bolster to permit the required vertical movement thereof, due to the action of the lateral motion bearing de-V *.vices; VBrake hanger lugs42 are cast with .the vertical walls tothe transoms 9., .just

'under .their flanges l0, and lower side bearing plates 43 are secured to the H-frame 36. To facilitate the casting oftheside frames 8 andthe assembling of the equalizerbars 21, openings are .formed in the ends and walls thereof. By reference to F ig. 2, it will be notedthat the dropped inner'langes 10 of .the transoms '9 afford suiicient clearl ance topermit the required vertical movement of the bolster 35. Normally, the pivot pins 31 vare held against endwise displacementby the vertical walls of the side members 8.v Tofpermit the application of the pivotvvpins 31 to the equalizer bars Y21` and Athe removal of the'same therefrom, annular bolster.

Y the .pivot pins 31, and to permit .said Ipins to lbe inserted or removed therethrough, it is necessary to lift the sidev frames 8 with respect `to the journal boxes 17. s V j 4 From'the above description, it is evident Y that Ythe load .of -thefcar is directly on the Adouble bolster and it, in turn, is supported from the truck frame by :lateral motion bear-ing devices. The truck fra-meandV load carrieduthereby .are .applied to the journal kboxes through the coiled springs and equalizer bars. "This construction, of course, S0 allows the `wheels to move vertically .and :inf dependently of each other. llVhat ave claim :is p Y 1.
