automobile battery industry since the organization in 
February, 1920, of the Westinghouse Union Battery 
Company as an offspring of the Westinghouse Air Brake 
Company. Though scarcely more than a year old, the 
new enterprise has made remarkable progress, having

to be followed in due course by signal system batteries, 
batteries for mine and industrial locomotives, for vehicles,
