The one horse-power machine shown in the picture was constructed with hand tools by staff and students of the Development Technology Unit of Warwick University, I UK. It consists of easily-worked mild steel and wood. The University researchers, aware of the desperate need for shaft power in developing countries, have updated the horse-gin, which was used in the UK until about 1920 for threshing grain, milling flour and many other agricultural jobs. In this new machine a scrap car wheel rolls around a circular track, guided by a wooden boom. The draught animal, which could be an oxen, horse, mule or even a camel, pulls the boom and wheel around. Power from the car wheel is taken by a shaft to the centre of the machine, then around several corners and finally out through another shaft, (which here powers the pump). If power is needed outside the circle, the shaft may be extended to go under the animal's track, in a duct or bridge. The new feature of this machine, which makes it cheaper and easier to make, is that power is taken through two right angles using universal or Hooke joints, instead of gears. This makes the machine tolerant of poor manufacturing standards and cuts out most of the expensive and difficult-to-make parts.
