journal box

Investigators determined that wreck resulted from an overheated journal box that caused an axle to snap.

Investigators later concluded that the journal box had burned off and an axle snapped at high speeds.

The main spindle at the front end works in a journal box c, that is cylindrical to fit the headstock, but double coned within to afford journal bearing to the spindle a.

The cast-iron shoes which serve as guides for the journal boxes also act as spacers between the pedestal plates.

For the test the front pedestals, which held the journal boxes of the leading wheels, were cut off and a Bissell pony truck was substituted.
