About the Photos

Most of the photos on this site were extracted from reference images (high-resolution tiffs, 20 to 200 megabytes in size) from the Library of Congress research archive. (To query the database click here.) Many were digitized by LOC contractors using a Sinar studio back. They are adjusted by your webmaster for contrast and color in Photoshop before being downsized and turned into the jpegs you see here.

Take No Chances: 1941

Take No Chances: 1941

December 1941. Goodrich plant at Akron, Ohio. "Rubber stock for track treads of scout cars and other Army halftrack vehicles is milled in one Ohio tire plant. All rubber firmly 'welded' to the steel parts is formed into one tough durable piece." View full size. 4x5 negative by Alfred Palmer for the Office of War Information.

 

Still in use in 1980

I've seen almost identical machines in the late 1970's at the Firestone plant in Los Angeles. They mix the rubber compounds after they come out of the "Banburys" that do the initial mixing. The drums contain cold water run through them. After the worker peels up the rubber from the drum, he will put the batch in the top, where it will be squashed & blended. The friction & compression would heat the rubber up to smoking hot. There have been several guys pulled into the machine over the years. The overhead bars are for an emergency stop to shut off the machine.
