William and Benjamin Douglas.

Tools Made: Grinding stone frames, lathes, pumps, hydraulic rams, machinery.

Working Dates: 1832-1923+.

William Douglas was born in Branford, CT. on 19 April 1812. He worked in the foundry business with his brother John in New Haven, CT. In 1832 he moved to Middletown, CT. and with W.H. Guild formed the company of Guild & Douglas, making steam engines and other machinery. His first patent was issued in August 1835 for a pump.

Benjamin Douglas was born in Northford, CT. on 3 April 1816. In 1832 he was apprenticed to a machinist in Middletown. In 1839 he and his brother William formed the company of W & B Douglas. From 1839 to 1842 they were a foundry and machine shop. In 1842 they invented a revolving stand pump. Then manufactured pumps and hydraulic rams.

An ad in ref. 9 stated they made castings in iron and brass, also made machines to order. Located on the corner of Broad and William Street. I have seen one example of their product, a large grinding wheel frame. Ref. 10 & 14 state the company was founded in 1832.

This is from Ref. 63:

Heavy-duty Lathe: W. & B. Douglas, Middletown, Conn. A single-purpose machine designed for turning and .boring shells, and for similar classes of general manufacturing work. All parts of the machine are heavily built to stand up under severe conditions of service. Three changes of speed and four variations of feed are available.

From Ref. 55:

The works are the largest and oldest manufactory of pumps in the country, if not in the world, covering 3 acres of ground and manufacturing 600 sizes and varieties. The motive power is furnished by two engines: 60 and 30-horse power respectively made by this company. They employ 200 persons, and their warehouse is at 85 and 87 John street, New York.

From Ref. 58:

At the 1876 Centennial Exposition in Philadelphia they had more 700 different articles on display.

These pumps covered many different used for both liquid and air.
