To all whom it may concern:

Be it known thatI, OTTo W. MEISSNER, a citizen of the United States, residing at Chicago, in-the county of Cook and State of Illinois, have invented certain new and useful Improvements in Bolsters for Railway-Cars, of whichthe following is a specification.

Thisinvention relates to that class of bolsters used in connection with railway freightcars, and particularly to what are known as built-up body-bolsters, a construction in which the bolster acts to form a part of the means for distributing the bolster strain and a part of the supporting-frame for distributing the shocks and strains throughout the car-frame, all of which will more fully hereinafter appear. The principal object of the invention is to provide a simple, economical, and efficient built-up body-bolster which will form a part of the supporting car-frame.

Further objects of the nvention will ap ear from an examination of the drawings an the following description and claims. i

The invention consists principally in a supporting-framework for railway-cars in which there are combined a pair of metal beams transversely arranged near each end of the car and secured together at the up er and lower portions by means of metal p ates, so as' to form a body-bolster, a pair of metal beams extending forward from the center of,

each body-bolster to the adjacent end sill of the car, a air of side sills extending longitudinally o the car and connected to the ends of the body-bolster, and a pair of longitudinal sills extending backward from the rear member of the body-bolster to the rear member of the body-bolster at the other end of the car.

The invention consists, further and finally,

, in the features, combinations, and details of construction hereinafter described and claimed.

In the accompanying drawin s, Figure 1 is a plan view, partly in section, 0 the suppor'ting-framework of one end of a railway-car as it appears when constructed in accordance with these improvements; Fig. 2, a longitudinal sectional elevation taken on line 2 of Fig. 1 looking in the direction of the arrow,

and Fig. 3 a transverse view taken on line 3 of Fig. 2 looking in the direction of the arrow.

' .In illustrating and describing these imtion other and well-known elements, which if set forth herein would only tend to confusion,

prolixity, and ambiguity.

In the art to which this invention relates it is well known that it is ver desirable to provide a supporting-frame or railway-cars such as flat-bottom, gondola, latform, box, and stock carsand make it oi as few pieces of commercial iron as possible and which will resist the shocks and strains incident to ordinary use of the car. To this end this invention is principally designed.

In constructing a car in accordance with these improvements I provide a supporting framework in which the body-bolster mechanism forms a art, such bolster mechanism being formed of a pair of metrl members a a.

' These metal members are preferably made of channel-beams, having their web por ons ar ranged in vertical planes and exten ing entirely across the car from side to side thereof and with their flanged portions extending forwardly and rearwardly, as shown particularly in Fig. 2. To com lete the bolster mechanism, a metal plate is provided and arranged on top of the supportin -frame work of a width considerably wider t an that of the main bolster members, to the upper flanges of which it is secured, andof a length equal to the width of the car, as shown particularly in Figs. '1- and 2. A similar plate 0 is provided and secured to the lower flanges of the bolster members and extends rearwardly therefrom, such bottom plate being provided at its rear edge with a flange 0, ormed of angle-iron, extending transversely of the car and riveted to such plate, forming in connection with the bottom plate and bolster-beams a transverse beam whose horizontal axis is on substantially the horizontal plane of the stress and strains incident to use.

not quite equal to the Width of the esr, as shown particularly in Fig. l.

A pair of center besnis d is provided, formed also of chennel-beems of substantially the some cross-section es the ()llfihl'lll' beams that form the bolster and arranged with their webs facing each other, as shown erticularly in Fig. .l.his pair of center eems is located in the eer freme Where the center sills were usiuilly arranged end-extend forward from the front member of the body-bolster to the end sill e at the end of the oer. A pair of side sills j'is elso provided, as shown in Figs. 1 end 3, and extend the en tire length of the car from end sill to end sill thereof, and are also connected, as shown in Figs. 1 and 2, by means of nngle-plates the ends of each of the bolster members.

To strengthen the supporting-framework of the cor, dispense with the usual center sills and efficiently assist in distributing'tlie shocks and strains incident to ordinary use, a pair of longitudinal sills his provided, formed of ll-beems of substantially the some height es the channel-beams a and iii-ranged intermediate the side sills and the forwardlyprojecting center beams from the inner memgto er of the body-bolster at one end of the cor to the opposite inner member at the other end of the ear, to both. of which they are soeured by means of engle-pletes i. (Shown in Fig. 1.) These intermediate sills are also secured (riveted) to the upper and lower letes b and 0, end, with the body-bolster iereinabove described, not in an effective manner to resist the shocks and strains incident to ordinary use, ill of which will be understood and appreciated by those skilled in the art.

In instances Where it is necessary to eleveto the platform of the ear the centenbesrleg portion j must be arranged considerably below the lower face of the body-bolster, end

in such instances it tiller must be provided. For such filler i prefer to use s an of con1- )ression members ll, formed or sn de-irons l I o secured together and to the center bearing and extending upwardly and outii erdly therefrom and connected to the plute 0. These compression members are arranged (ll-- rectly under the cluinnel-beimis, which form the main members of the body-bolster. pair of draft-timbers t is provided, secured to the forward port ol the filler and ex tend for wnrdly therefrom to the end of the car and to which the ordinary check or draft pistes in may be secured.

To prevent buckling ol the elmnnebboums tluit loi'mthc main members of the body bolster, motul inserts or fillers p are pro-- vidcd :uid ll'l'llllf,((l between the webs ol' the cluiuiicl-bczuus, as shown pzu'ticulm'ly in Fig. l, and opposite the iulci'mcilistc sills. A second set oi pair of Li-sluipcil inserts (I is also provided and arranged between the Webs of the same members, as shown in Fig.

ter beams to resist any tendency to buckling at such points.
