ie it known that l, lllnviii W. wWEBB, a

citizen of the United States, residing at Vliicago, in the county of Cook and State of 1 Illinois, have invented certain newiand U58- fiil Improvements in (far-'l`riicksg and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled inhthe art to which it appertains'to make and lise the saine.

My invention relates to car tri'icks -and `has for its object to improve the same in the several particulars hereinafter noted.

. Generally stated, the invention consists of the novel devices andcombinations of devices vhereinafter described and defined in the claims.

In the accompanying drawings which illustrate lthe invention, like characters .indicate like parts throughout the several views.

Referring to the drawings: Figure 1 is a lview in side elevation showing a car truckembodyingmy invention, the journal boxes being removed and the wheels beingv indicated in diagram; Fig. Q is a transverse section. taken through m2 nf" on Fig. l, some parts being shown in full; Fig. 3 is a horizontal section taken the irregular line .r3 w on Fig. l; and Fig. l is a detail in section on the line o? m4 on Fig. l. The triiek side frames 1 are caststeel or formed with top compression members, bottom tension members and bolster columns, all cost integral. These side frames of thetriick 'are formed with truck bolster openings, the lower por tions of which are slightly narrower than The. 'side frames l are webs and with out-A the upper portions. formed with central wardly and inwardly projecting marginal flanges, and the tension members thereof,

at their central portions, are formed with 4spring receiving-pockets 2 located, two on the outer side and two on the inner side of the central web.. The inside pockets il are formed with projecting flanges 3 raised above the bottoms 'of the pockets, and to which the trnck cross ties fr are riveted, or otherwise rigidly secured. ties e, as shown, are rolled steel angle oars and the said tis-hojas 3 ere formed with both poi'i",iea s to which the truck Ion the linel The said cross rateale@ raar so, loro:

Application ined my i, wir. serial no. 25,992.,

the horizontal and vertical Heiliges of the said angle bars are riveted, gussetv plates 5 being preferably interposed between the said parts, as best shown in Fig'. 2. The truck springs 6 are seated in pockets 2, and it is important to note that Withs-the orrangemen't described, the lower ends of the said springs are brought downbelow the bottoms of the cross ties, thereby making possible the'use oi 4very high or lon truck springs, lwhich are much in deman at the present time, without lowering1 the cross ties, and without increasing the` hei lit of the bolster and side frames. Also, tis ary rangement gives great .and siiicient depth to the central portions Aoli .the truck side frames to take care of heavy loads required in the present railway service. 5

The truck springs 6 support' combined spring cops and roller bases ''provided with notches 8 in their ends, that embraces the bolster columns of thetriick side .frames and hold the said elements 7 for vertical movements and against 'horizontal movements.'

On their iipper surfaces, the said combined springl caps and roller bases 7 are concave, or self-centering roller seats 9, on which lateral motion rollers 10 are seated.

The truck bolster l1 1s preferably ol a 'II cast steel structure, and, at the under siirface of its end portions, it is provided with roller seats 12 that rest upon the rollers 10. T he truck' bolster is thus mounted forv lim.- ited endivise movements, transversely of the truck. To limit the endwise movements o1E the saidbolstcr, transversely of Athe truck, it is provided with integrally cast or formed stop lugs 13 that are arranged to engage the inner edges of the. combined spring caps and roller bases 7. T he endwise move ments of the truck bolster are, therefore, limited by the combined spring caps and roller bases, the latter beingfheld against horizontal movements,

with the bolster columns of the truek side frames.

In asseinbling the parts oa truck, the holster is lfirst pushed through the side frames. This can be done because' there are no stops on the sides of the bolster, and because the stops 13 do notL engage with the bolster columns of the truck sideframes. When the bolster is properly centered in rergoeet to track, it is raised op,

and the transversely .of the y combined spring caps and roller bases are applied by inserting them into the openings While turned obliquely, in respect to a horizontal, and then turning them into horif, aantal positions while their notches 8 are alined with the bolster colnmns. Here it may -be note'd vvthat the column-engaging faces of the notches 8 are slightly rounded at 8 (see Fig. l), so that the above noted engagement is made feasible Without eX- cessive clearance. The combined spring caps and roller bases are then lifted up and the springs are'then applied, and then the combined spring caps and roller bases are pressed down upon the springs and the .ollers are applied.

By securing the cross ties to thelinside of the frame, as described, th'ey are ,kept

high enough to permit all of the braking levers and cooperating parts to Work free at a good height above the rails., I give sufficient riveting space for the cross ties, by the use of gusset plates attached to the full width of the inside bracket ror flange 3 and extending* back to rece/ive about three inwardly projecting cross tie brackets raised above the `bottoms of said pockets, gusset plates riveted to said brackets above the bottoms of said pockets, and a flanged cross tie having,r its ends riveted to said gusset plates and to said brackets and located entirely above the bottoms of said pockets.

2.-l In' a car truck, truck ,side frames having bolster` openings and provided with bottom tension members formed with central webs and with spring:r seating pockets located both in the inner and outer sides of said central web, and inside pockets having angular cross tie brackets raised above the bottoms thereof, and angle cross ties riveted to said brackets and located entirely above the bottoms of said pockets.

3. In a car truck, the combination with truck side frames having bolster openings and spring seats, of springs on said seats, spring caps 4o said springs `guided for ver tical movennts bysaid side frames, but held thene' y against lateral movements, lateral /otion' devices on said spring caps, and a/ ruck bolster mounted on said lateral m ion devices and provided with integ";;l depending stop ln's engageable with said springr caps to limit the movements of said bolster transversely of the truck.

In testimony whereof I afix my signature in presence of two witnesses. EDWIN W. WEBB.
