Vertical engines are sometimes referred to as " hammer ", " forge hammer " or " steam hammer " engines, due to their roughly similar appearance to another common 19th-century steam technology, the steam hammer.

The device consisted of a concave mirror 3.5 meters in diameter centering on a cylindrical steam boiler, which powered a small vertical engine of 2 / 5 horse power, and then driving a Marioni type printing-press.

In early locomotive practice, the eccentric rod ends were pivoted at the ends of the link while, in marine engines, the eccentric rod pivots were set behind the link slot ( or below on a vertical engine ).

With enough sweep-back, differential drag is sufficient to naturally re-align the aircraft . This is the stabilization scheme used in the early Northrop flying wings, in combination with vertical engine nacelles ( YB-35 ) or diminutive stabilizers ( YB-49 ).

Two and a half years later, having won American and French contracts to sell their airplane, they refurbished the Flyer with seats for a pilot and passenger, equipped it with upright control levers and installed one of their new 35-horsepower in-line vertical engines.

Two other steam engines that were present in 1973 are no longer on site-a Tangye, Birmingham single cylinder vertical engine and a Thompson & Co ., Castlemaine, Victoria, single cylinder horizontal engine no . 242 ( earlier used by Mount Lyell Mining and Railway Company ).

Austin then provided a paragraph as to why his horizontal engines were better lubricated ( than vertical engines ) and that 750 rpm, the speed of his Wolseley engines, avoided the short life of competing engines that ran between 1, 000 and 2, 000 rpm ."
