lBeit known that CHARLES T; Serious, e Vcitizen'of.the Unitedgtetes, reeidingat Phila ldelplximiiithe county of 'Philadelphia and have invented a' cer- Qtaiu newand usefull improvement in Holsters l :for Railway-Cars, of which the following isa 'fullgeleamaudexaet description; This invention relates to a bolster preferio ablybuilt'up of pressed-steel shapes and `designed for use in ,truck-frames of the diamond variety, such as illustrated. in special ferm in l'atent'Na 587,886, dated .August 10, 1897, and'alsolinaerdinary arch-ber frame, as is in x 5 common use.

`lheiinvention consists ine-bolster of box form comprising a girder substantially. U shape in cross-section,having its 4top closed by a cover channelf'plate, also substantially 2o U shape in cross-section,and fitted within 3o bottom is.

and riveted to the sides of the girder, the girderlbeing braced at its ends and centrally, as l will proceed more particularly to set forth and finally claim.

The bolster is provided with a center-bearing plate, side bearings, and dialing-plates of appropriate form end construction.

In one forrn of my invention the bolster is substantially level' ou its top surface and its bellied,aud in another form the bottoni is substantially level and its top is bellied.

Referring new more especially to the bolster of Figs. l to el, t is a girder of substantially U shape in cress-scetion, as shown in Fig. 3, having substantially horizontal ends 1.' and a bellied center o?, as usual. b is a Fig. 7 is a een- B10 LSTILEH FU lit lil/tl LWVAYHCASS.

channel-plate, also substantially U shaped in crosssection and inserted in thetop of tlic girder and united therewith laterally, as bjr' rivets b'.' "c are center braces constructed and arranged to operate substantieily as in my Patent No. e are end braces, f side bearings erected on the channel plate, and plate, also erected on 'the channel-plate, and h are chatting-plates secured to the sides of the girder. l `Referring new tothe bolsterillustrnted 'in Figs. l5 to 8, t' is the girder, mede, before, in substantially the shape in crosssection el theletter U, but dilering from the girder illustrated in Figs. l to l in that its bottom is level, While its upper surface has, rr pectitely, the substantiallyliorizentalen'ds t end the bellied center t2. This upper or top -portion is provided with a channel co.verplatc 7c, bent to conform to tlie outline of 'the top of the girder, also substantially ilv shape in. cross-section and secured within and to the girde'r. by rivets 7o or other fastenings. l are the center braces, of substantially the construction before described. m are the end braces, which, as shown in the details, Fig. 8, may be composed of iiat plates appropriately' slitted and the ends und sides bcntjup to form a box-like structure. n. are the side bearings, erected ou the cover-plate. o is the centerbeetring plate, which is erected en a tillera plate p, which latter is secured rigidly to the cover-plate and gives tbe proper elevation to the center-bearing plate. lr are the chaiingn plates, secured to the sides of the bolster at its ends.

As already indicated, my iznlnoved holsters and their attached parts are preferably inode up of preesedsteel shapes and are asseuxblcrfi by riveting or otherwise, as desired.

Drain-holes, as s, may be provided allseitable intervals or places in bet-l1 1orme of belster.

lt will be observed that belli forms of my invention are practically.boxed girdere.

'lhere is a heavystrain on thet-rr .lz-boleter' of a freigbtear, due to horizontal cone ussions, in addition to the Vertical lead to be sus`- tained thereby. The built-uptypeelf bolster heretofore made is not nearly so streng ina transverse direction as in n. Vertiealdiaeetion,

g a centerbearingv sei and I have demonstrated that this desiredincrease of strength in the transverse direction may be obtained by making the bolster practically in the form of a boxed girder, subits sides and bottom are one solid piece.

The upper portion, containing the cover-plate b and where the riveting is done, is in com pression, and for lthis reason there is very slight liability of rupture or fracture to'the riveted portions. Another point of superiority in the present construction of bolster is that all of the riveting can be accomplished by machines, a thingwhich could not readily be done in the built-np holsters commonly made, and by this capability very superior work may be .done and at a cost of less than half as compared with hand-riveting. lFurthermore, this formof bolster may be applied to trucks having two cross-transoms uniting the two side frames of the truck, and it is also applicable for interchange in all styles of common diamond trucks.

What I claim isl. A bolster, comprising a body member made U shape in cross-section and having it-s top' covered in by a substantially U-shaped channel cover-plate, inserted within the body and secured to its sides substantially as described 2. Abolstcr,:colnprising a member U shape in cross-section, with one surface substantially leveland the opposite surface bellied, and a channeled cover-plate riveted within and to the sides of the U -shaped member, substantially as described.

3. A bolster, comprising a body U shape in cross-section, and a channel cover-plate arranged within the sides of the body and united therewith, the whole constituting a boxed girder, substantially as described.

. 4. A bolster, of bex form, comprising a girder U shape in cross-section, having its top closed by a cover channel-plate inserted between and riveted to the sides of the girder, and end and center braces, substantially as described.

5. A bolster, comprising a body membern made U shape in cross-section, and having' solid sides and bottom, and a top member arranged within and riveted to the sides of the body member, and the whole constructed of pressed steel, substantially `as described.

6. A built-up bolster, comprising a body member made U shape in cr'oss-se'ction, and

having its top covered in by a channel coverplate arranged between and riveted to its sides, and adapted for interchange in ordinary diamond trucks, substantially as described.

In testimony whereof I have hereunto set my hand this 18th day of February, A. l). 1898.
