Abstract
A railroad car sideframe of a truck is provided with a pair of identical twin ribs which are designed to reinforce and strengthen each of the pedestal frames against stress failures caused by the large railroad cars being built today and the heavier loads which they are capable of hauling. The use of these twin ribs simplifies the machining operation used in the fabrication of the pedestal frames.
Claims7
A sideframe for a railroad car, comprising:
- a) at least one pedestal frame having an inverted, generally U-shape and designed to support one end of a wheel and axle assembly, said at least one pedestal frame including, in cross-section:
- b) a first member having, I) a planar web with opposing parallel marginal edges, II) a pair of flanges integrally formed with the web and extending from the marginal edges of the member in parallel relation away from the web, and III) at least one solid rib integrally formed with the web between opposing marginal edges of the web, the at least one rib extending from the web in an opposite direction from the flanges and being parallel to the flanges, the at least one rib reinforcing the pedestal frame and having a free distal end with a smooth outer surface;
- and
- c) a second member which is separate from the first member and has, IV) a planar web which is parallel to the planar web of the first member, and V) at least one flange integrally formed with the planar web of the second member and extending therefrom into abutting relation with the rib, the at least one flange of the second member having a free distal end which is secured to the smooth outer surface of the rib.

A railroad car truck, comprising:
- a) at least one side frame including at least one pedestal frame supporting an axle box which is designed to support a wheel and axle assembly, said at least one pedestal frame comprising:
- b) a first member, in cross-section, having;
- I) a planar web with parallel marginal edges, II) a pair of flanges integrally formed with the web and extending from the web in parallel directions towards the axle box, and III) a pair of solid, identical twin ribs which are integrally formed with the web and extend from the web in parallel directions away from the axle box, the ribs being sufficiently sized to reinforce and strengthen the adjacent pedestal frame to which the ribs are secured, the ribs having distal ends with machined outer surfaces;
- and
- c) a second member, in cross-section with the first member, having a planar web with outstanding flanges which extend in parallel relation towards the machined surfaces of the twin ribs, the outstanding flanges of the second member being connected to the machined surfaces of the twin ribs.
