Jewett self-heating can

Contributed by Maine Historical Society

This drawing shows the mechanics of the self-heating can, used in food processing in the early 1900s.

The can had a central chamber holding a substance that would release heat when put in contact with water, such as lime. Water could be dropped in and the resulting heat would cook the surrounding vegetables.

The inventor, George S. Jewett, claimed it was "just the thing or light housekeeping, picnics, camping, yachting, sportsment, etc.."
