Weeden No. 23 Hot-Air Engine Toy

Description (Brief)
The Weeden Manufacturing Company of New Bedford, Massachusetts produced this number 23 “hot air” engine from the 1890s until 1916. The engine is not a steam engine, as no water is heated. Instead the firebox heats air which expands and moves a piston to create useful mechanical work. The toy consists of a vertical firebox, with a nickel-plated horizontal engine that drives a 2.25-inch flywheel all mounted on a cast iron base.
The Weeden Manufacturing Company was founded in New Bedford, Massachusetts by William M. Weeden in the early 1880s, originally producing a variety of tinplate household items. In 1884 it introduced the Weeden No. 1 Steam engine as “a new and great premium for boys” who were subscribers to the Youth’s Companion magazine. Weeden made over a hundred different models of toy steam engines until the company ceased operations in 1952.
