A roller bearing hot box sensor utilizing a metallic temperature sensitive elongated wire element. The wire element contracts at temperatures in the range of about 125°F. to about 225°F. so that when the contraction movement of the wire is attached to a connector means that operates a firing pin. Movement of the wire element initiates an electrical battery or other power source and thereby transmits electrical current to a signaling device, that gives a signal.

A roller bearing, hot box temperature sensor designed to be mounted in a train with wheels, where the sensor functions to control and stop the train in response to temperature changes sensed in the wheel bearing assembly comprising a housing for mounting a temperature sensor in close proximity to a train wheel bearing assembly with an opening within said housing combined with metallic means capable of contracting in response to rapid increases in temperature and where one end of the metallic sensing means is permanently fixed on one end to the wheel bearing assembly and the opposite end of the metallic means is attached to a mechanical control means that is actuated by contraction of the said metallic means and where the contraction of the metallic means functions, through the mechanical control means to stop the train wheels when a certain temperature is reached.
