A side frame bracket assembly for positively retaining an axle bearing carrier assembly within the pedestal opening of a narrow pedestal type side frame of a railway truck assembly comprising:
- a retaining bracket adapted to be carried by a pedestal jaw of such a pedestal opening adjacent a lower end portion thereof;
- biasing means adapted to be carried by said bracket and disposed intermediate such a pedestal jaw and such a bearing carrier assembly and operative to bias such a bearing carrier assembly out of communication with such a pedestal jaw and into communication with the other pedestal jaw of such a pedestal opening continuously during all normal moving operation of such a railway truck assembly.
In a railway truck assembly having narrow pedestal type side frames which captively receive an axle bearing carrier assembly in the downwardly open pedestal opening formed by a pedestal roof and transversely spaced vertically extending inboard and outboard pedestal jaws, the improvement comprising:
- biasing means disposed intermediate one of said jaws and said bearing carrier and operative to bias said bearing carrier out of communication with said one of said pedestal jaws and into communication with the other of said pedestal jaws during all normal operations of such a railway truck assembly;
- and said biasing means continuously imparts both upward and horizontal force components.
A method of positively retaining an axle bearing carrier assembly within the pedestal opening of a narrow pedestal type side frame of a railway truck assembly comprising the steps of:
- biasing said bearing carrier assembly out of communication with one pedestal jaw of such a pedestal opening and into communication with the other pedestal jaw of such a pedestal opening;
- maintaining said last mentioned communication through the normal operation of said railway truck assembly;
- and said biasing continuously imparting both upward and horizontal force components.
