Carburetor
The first carburetor was invented by Samuel Morey in 1826. The first person to patent a carburetor for use in a petroleum engine was Siegfried Marcus with his 6 July 1872 patent for a device which mixes fuel with air.
Gas turbine locomotive
A gas turbine locomotive was patented in 1861 by Marc Antoine Francois Mennons (British patent no. 1633). The drawings in Mennons' patent show a locomotive of 0-4-2 wheel arrangement with a cylindrical casing resembling a boiler. At the front of the casing is the compressor, which Mennons calls a ventilator. This supplies air to a firebox and the hot gases from the firebox drive a turbine at the back of the casing. The exhaust from the turbine then travels forwards through ducts to preheat the incoming air. The turbine drives the compressor through gearing and an external shaft. There is additional gearing to a jackshaft which drives the wheels through side rods. The fuel is solid (presumably coal, coke or wood) and there is a fuel bunker at the rear. There is no evidence that the locomotive was actually built but the design includes the essential features of gas turbine locomotives built in the 20th century, including compressor, combustion chamber, turbine and air pre-heater.
