HE WESTINGHOUSE UNION BATTERY
COMPANY

Pittsburgh has been prominently represented in the
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
already gained nation-wide recognition in the battery field.
The product thus far has been limited to batteries for
automotive starting, lighting and ignition, but storage
batteries for house-lighting plants will be added shortly,
to be followed in due course by signal system batteries,
batteries for mine and industrial locomotives, for vehicles,
for central station work, and in fact, for every purpose for
which storage batteries are required.
The Company’s plant is housed in the large five-story
modern fire-vroof buildings erected by the Union Switch
