Year: 1910Manufacturer: DethridgeType: Dethridge WheelTypical use: AgricultureThe wheel was invented by John Dethridge in Australia in 1910. Dethridge was then commissioner of the Victorian State Rivers and Water Supply Commission.
The wheel consists of a drum around an axle with four spokes originating from each end of the axle. Eight v-shaped vanes are fixed to the outside of the drum which then spins. Wheels generally last for 15 to 20 years, and the axle is replaced every five years.
The revolving wheel measures the flow of water from the irrigation supply channels into the farm channels. This provides the basis upon which irrigation farmers are charged for water. |
