Lemuel Wellman Wright

He opened a clock-making shop in New York City before accepting a position to introduce American textile manufacturing machinery to the United Kingdom of Great Britain and Ireland.

There are contemporary references to an American from Massachusetts, Lemuel William Wright, who patented machinery and created a factory to make pins in London.

In London he built "a large stone factory in Lambeth, and constructed some sxity machines, at great expense.

In summarising the importance of patents prior to 1860 (when the internal combustion became a commercial reality), Clerk states : "The greatest credit is due to Wright and Barnett.

The gas and air are supplied to the motor cylinder from separate pumps through two reservoirs, at a pressure a few pounds above atmosphere, the gases (gas and air) enter spherical spaces at the ends of the motor cylinder, partly displacing the previous contents, and are ignited while the piston is crossing the dead centre.

Both cylinder and piston are water-jacketed, as would have been necessary in a double-acting gas engine to preserve the working parts from damage from the intense heat of the explosion.
