Although best remembered for his car and his driving, he had, for many years, been an inventor and a designer of steam-powered machines, which he used for agricultural work and early road transport.
Steam powered road vehicle In 1868 he built a steam powered road vehicle, although it was not a practical proposition due to inefficiency.
Steam powered hop digging machine In 1872 Knight developed a steam powered
hop digging machine. A rival designer, Frank Proctor, stated in an 1890 edition of the weekly magazine "Engineering" that "Mr Knight has undoubtedly earned the distinction of being one of the early pioneers in the system of steam digging". He had begun developing his first digging machine in 1872, specifically for working in
hopfields, which are difficult to cultivate due to the incidence of the hop poles which support the strings up which the plants climb. "Digging by Steam" by Colin Tyler (published in 1977 by Argus Books Ltd) devotes a chapter to hop digging machines, many of which were designed and built by Knight, and which are illustrated with drawings or photos.
Other inventions His other inventions included - • Knight's
Thermosote Heat Saving Radiator, for which patents were applied for; • a brick laying machine; a wall that it built still stands at Barfield School in Runfold, but the machine's main flaw was an inability to turn/build corners. • a
grenade thrower, • a
speedometer, •
wooden vehicle tyres, • Knight's patent 'dish lever' for tilting plates when carving meat.
Photography He was a keen photographer and pioneer of early colour photography, photographing Farnham and the surrounding countryside in the early years of the 20th century.
