Some of the choicest engravings of early steam engines which we have seen are those from the Erie City Works of Erie, Pennsylvania. Two handsome horses pull the 6 to 20 HP portable with the driver probably not having to exercise the whip he holds in his hand. Details are exceptionally clear. For the Erie owner of today, this can furnish excellent documentation. Another superb picture is that of the 5 to 10 HP portable, shown without the horses.
The stationary engine, with or without variable cut off, shown with a workman, is also a delightful portrayal. Erie City made portable and stationary engines, boilers and circular saw mills, steam riveters, torsion spring hammers and Carroll's patent gang saw tables.
Stationary engines were made in 14 sizes, from 8 HP to 125 HP. Detached portable engines were built in six sizes, from 8 HP to 30 HP.
These pictures are shown in the Asher & Adams Pictorial Album of American Industry, published in 1876 and now republished by Rutledge Books.
