Charles W. Pinkney started work with Tangye in 1876 and worked closely with Robson, (whose engines were being made by Tangye) on his gas engine, Pinkney’s inventiveness and experience made him extremely valuable to Tangyes in these years. He was soon given charge of the gas engine ‘sheds’ and his opinion was relied upon for the assessment of new gas-engine inventions submitted to the firm.
By 1889 Pinkney had developed his own gas engine but the ‘Otto patent was rapidly running out and it was eventually decided in the Spring of 1891 to start manufacturing a four-cycle engine on the ‘Otto principle rather than to proceed with the unknown Pinkney model.
The "Otto" Principle, Pinkney Patents Gas Engine designs brought a large increase in trade
These engines featured the following features
* Mild steel forged crankshaft.
* Supplied with two cooling tanks, exhaust silencer, cast iron gas bag.
* Electric Lighting engines were fitted with two flywheels
This type of engines carried a Tangyes Gas Engine, Pinkney Patents plate that can be seen on Tangye Plates Page.
