ITNESSES Allorney ll desired, each mern ers may consist of two channel-irons placed back to back, as shown in Fig. 4, and the depressed seats for the side-sills formed by slitting and bending, as before explained. When this construction of cross-bearer is employed the two channel-iron men'lbers may be slightly separated to receive the end fthe truss 18 between them,-in which case the top flange of the truss may be removed, as shown in Fig. 5, or the channel iron members may be placed back to back "and the truss secured to the bottom flanges. Other slight changes might be made in the details of construction of my invention with out departing from the spirit thereof or limiting its scope, and hence I do not desire to limit myself to the precise details herein set forth.
Having claim as new and desire to ters-Patent, is
fully described myinvention what secure by Let- 1. in a car underframe, the combination 5 her of the cross-bearl with l l g i i i a center secured thereto,
girder, of transverse mem bers each of said transverse members slit vertically near the outer end and bent laterally and downwardly, forming depressed seats for longitudinal members,- and a bracmg member secured to the center girder and tothe side of 2. with the transverse member. In a car'underframe, the combination;
a center girder, of a prising a plurality of transverse members sccured tothe center girder, the outer end of each transverse member slit bent laterally and (low depressed seat for a lo means secured to the side faces bearer members.
and bracing oi the cross vertically and nwardly, lOIHllIlg a ngitudmal member,
In testimony whereof, I have signcd'this specification in the presence of two SUl)S(Ill)- 1n; witnesses.
