Figure 7 is a top plan view thereof, with adjacent portions of the side frame being shown in horizontal section,

Figure 8 is a detail vertical cross sectional view on the line 8-8 of Figure 7.

Referring to the drawings in which similar reference characters designate corresponding partsin the several views, my improved spring plank construction is shown applied to a wrought metal side frame having an inner wall 1 and an outer wall 2, each of said walls being formed with top arch bar portions forming the compression member, bottom arch bar portions continued beneath the bolster opening to form a beam member, and truck column portions uniting the compression and beam members of the side frame. The truck columns are indicated by the numeral 3 and the beam member by the nu meral 4c, the spring plank saddle casting or seat member 5 being positioned upon the beam member and embracing the inner and outer walls of the side frame, as shown.

In my present construction the inner and outer walls of the side frame are provided with inwardly extending stiffening flanges, said flanges bordering the top arch bar portions, bottom arch bar portions, and truck column portions, the flanges on said portions adjacent the bolster opening being designed to surround or border said opening. The column stiffening flanges are designed to merge into connecting flanges (3 which border the lower end of the bolster opening, said flanges heretofore being adapted to receive the vertical loads imparted to the side frame through the seat casting.

My present construction of spring planl-z saddle member has been designed to distribute the vertical loads to the inner and outer walls of the side frame without increasing the relative thickness of the body portion of the seat casting or reducing the depth of the beam member of the side frame, it being obvious that in the maintaining of the relative thickness of the body portion of the saddle casting that the depth of the bolster opening will remain constant. The body portion of the seat casting 5 is provided with projections 7 at each end thereof, said projections being adapted to rest upon the inwardly extending stiffening flanges 6 at theirjunctions with the stiffening flanges of the truck columns. The projections 7 mainly rest upon the side frame portions at the j unction of the inwardly extending stiffening flanges and the inner and outer walls respectively, said projecting portions being outwardly flared at these junction points so as to overlie relatively large portions of the inner and outer walls, as best shown in Fig ure 2. he under-face of the seat member is provided with a projection 8 of relatively less depth than the projection 7, said projection being disposed transversely of the seat member and adapted to contact the stiffening flanges when excessive loans are received. In addition, this relatively short projection 8 serves to reinforce the relatively thin body portion of the casting transversely thereof. Portions of the projections 7 are relatively reduced in cross sectional area, as indicated at 9, these reduced portions permitting of an increased depth of beam member at the critical points of the side frame.

The upper surface of the saddle casting in the construction shown in Figures 1 to 5, inclusive, is designed to receive a spring plank, an upstanding annular rib 10 being provided on said surface adapted to form a pivot boss for co-action with the spring plank. Depending longitudinally extending ribs or flanges 11 project from the under-face of the body portion of the casting, said flanges being adapted to embrace neighboring portions of the car truck side frame. The flanges ll are braced by angular webs 12 connecting the body portion therewith. The ends of the flanges 11 are continued upwardly at each end of the seat member and form bracing webs 13 for the upstanding ribs or flanges 1% dis posed transversely of the seat member at each end thereof. The transverse upstanding ribs ll unite the depending flanges 11 at each end ofthe seat member and act to transfer the lateral loads to said flanges l1 longitudinally of the side rame. lhe intermediate portion of the transvc ce flanges 1-1 is relatively enlarged, as indicated at 15, s id enlargement being disposed in central longitudinal alinement with a main reinforcing rib 16, the upstanding ends of which are connected to said enlarged portions.

The reinforcing rib l6 depends from the underface of the body portion of the saddle member, said rib being preferably located centrally thereof ano of a depth greater than the depending side flanges ii. The rib 16 extends the full length of the casting and is designed to reinforce the relatively thin cross sectional area lying between the projecting

portions

7 and 8. A reinforcing flange 17 is preferably provided along the lower edge of the rib 10, said flange being preferably increased in width centrally of the ci lSilllg', as shown. Vertically disposed. bracing ribs 18 unite the projecting portions of the flange 17 to the web section of the rib 16 and the to the body portion of the casting are trans .1 springs llf) All

mitted through the contacting projections 7 to the side frame, the loads intermediate said projections being resisted by the reinforced interniiediate portion of the casting and transmitted to the sides thereof overlying the inner and outer walls of the frame.

Referring to Figures 6 to 8, inclusive, there is illustrated a mocilied construction of spring planl; saddle casting in which a relatively short spring pla l: 19 is employed, said planlcbeing connected to the und rface c an extension 20 projecting inwardly of the side frame from the body poi n 21 of the sac dle casting. A pluralit of rivets 22 rigidl connect the spring plank to the extension or projection 20, said rivets being located upon opposite sides of an upstandin rib 23 uniting the upstanding transversely disposed ribs or ilanges 24 arranged at each end of the casting. The upstanding rib 23 is argulariy disposed. with. respect to the long alinement of the connecting ivets 22, said rib passing between alternate rivets and f-rrn ing a gusset construction of maximum strength value. The innermost ends of the upstanding transverse rib; Qare continuec inwardly beyond the gusset-like rib to the innermost edge of the extension LO, thereby reinforcing the metal along one side of the rivet opening. The inner edge of the c. tension 20 may be cut away toward the intermediate point-like portion of the upstanding rib 23, as shown.

The depending longitudinally extending flanges 25 of the modified construction have their inner pposed faces shaped so as to pro vide intermediate fulcrum points 26 about which the casting is capable of rocking with respect to the'side frame. T he opposed inner I faces of the flanges are outwardly flared toward each end thereof, the intermediate portions providing extensions about which the casting may swing in resisting the loads. This rocking movement is d sirable in that it allows angling of the spring plank so as to pro igressively resist the loads and reduce the shear strains upon the rivets rigidly connecting said spring plank to the projection or extension 20. The outer longitudinally extendingv flange 25 is preferably braced by the angular web adjacent the fulcrum point, as shown. v i

The longitudinally disposer reinforcing rib 27 depends from the body portion of the casting and serves to reinforce the relatively thin cross sectional area of said body portion between the projections 28 contacting the flanges of the side frame. The lower edge of the reinforcin rib 27 may be suitably flanged, as indicated at 29.

The outer edge of the modified construction of saddle casting is provided with an upstanding wall 30, said wall acting to retain the bolster springs in position. The wall 30, transversely extending ribs 24, and

the upstanding reinforcing rib 23 provide an upstanding enclosure borde "ing the spring seating surface, said construction adding to the strength value of the casting.

A spring plank constriction involving saddle casting constructed in accordance i ith he present invention is comparatively light in weight and of great strength value, it being understood that my particular construction is capable of use with type; of side frames other than that described wherein it is desirable to roll ve portions of the beam member of the side frame of the verticz l loads and the same time provide a casting of sufficient strength. value while maintaining a constant depth of bolster opening, maximum depth of beam member am th required rail clearance. It will be observed. from the present constriction that the princ'pal reinforcing rib is let down between the inwardly e:-: tending stiifening flanges of the side frame, which flanges are sutiiciently spaced from the body portion of the saddle casting as to pr vent their deformation under service conditions.
