He went on to invent several things including a nozzle to increase a steam jet to supersonic speed, which today has been incorporated into the modern rocket engine.
He then turned his attention to a centrifugal oil and water separator, which proved to be highly successful. This is then led to the thought of separating cream from milk, a system that he patented in 1894. He was now faced with the problem of developing a machine to mechanically milk cow's and speed up production. He worked on several prototypes, none of which were successful. Others tried and offered their ideas to him, but they too failed the test. It was not until five years after his death in February 1913, that his research and development group came up with a model on which todays milking machines are based. The earlier versions of which were incorporated into the White Place Farm cowsheds before the arrival of the new milking parlour in 1937.
