Before the time when replacement parts were ordered on-line and shipped overnight, companies repaired and replaced broken machine parts on-site.  Machine shops were scattered throughout the city, owned by machinists that took on young apprentices to learn a valuable trade.

The Machine Tool Shop exhibit displays belt-driven machines, which are often running courtesy of our dedicated volunteers. 

There are samples of larger machines and tools, including a Duplex Steam Pump invented in 1841 by Henry R. Washington that was an important breakthrough in the Industrial Revolution.

Also on display is an original White & Middleton Co. engine, dedicated to long-time Board Member and friend of the BMI, Edward L. Middleton. 

Another important invention in Baltimore that is documented here is the first Submarine, in 1897 by Simon Lake at Columbia Iron Works and Drydock Company.  This submarine, named The Argonut, sailed from Norfolk to New York and was the first successful operation of a full-sized submarine in the United States.

Large and influential inventions like these are what make the machine shop, with machines in working condition, one of the most intriguing galleries here at the BMI!
