In 1879, Cobb, Herrick & Company was building boilers at 117 and 123 East Water Street.

In 1922, Harold Yarrow decided to exploit the increasing boom for electricity generation as a market for Yarrows to build land-based boilers.

It went on to build boilers, steam lorries and gas engines as well as gaining a reputation as a builder of water wheels.

By 1900 they were building boilers, steam engines, locomotives, internal combustion engines, blowers, and air compressors.

The company also built engines and boilers for other shipbuilding firms.

Later, it built sawmill engines, blast engines, boilers, and even a steam fire engine.

Associated with the shipyard was the engine works where the company built turbines and boilers both for its own ships and for other companies.

A few plants will try other solutions, like building new boilers that produce less pollution, or burning coal with natural gas to cut emissions.

There was also a $25 million charge for cost overruns to correct performance problems with Riley Consolidated, a subsidiary that builds boilers for power plants.

They no longer build locomotives, instead building ships, wagons, and boilers.
