Not illustrated. 1913 Excerpt: ... on the three ports, d, are opened, and vice versa. The operation of cleaning is as follows: The raw water is shut off, and a reverse current is passed from the left-hand side of the cylinder through the pipe N, the passage I, and the ports e, e, e, into the space beneath the screen on which the quartz rests, whence it rises through the quartz. While this is going on, the cylinder is rotated by worm-gearing and pinion, so that the bed of quartz is turned over and over as the wash water mingles with it. Very soon the water rises to the level of the port H, and begins to overflow to the waste-pipe. As soon as this happens, the lever G is used to close H and open the three valves on the under-side. These at once siphon off the dirty water, and clear it away before the sediment which it carries has time to settle. The process is now repeated, more water being admitted and again siphoned away until the wash ing is complete. The crank-pipe E' does not revolve with the cylinder, and the port H is always directed upwards. The bed is divided by transverse partitions into three compartments, and for this reason there are three ports below and three valves above. With this arrangement it is possible to wash the compartments separately, and concentrate the whole weight of the wash water on one at a time. For the ports are also provided with valves, which may be closed at will separately by a lever outside. In general, two outlet valves are in position at the left-hand side, so that, if necessary, the first runnings after cleaning may be led to waste. The cylinder, it will be noticed, is supported by rollers so as to relieve the strain on the trunnions. Motive power for revolving the filter is obtained from a motor or otherwise, as convenient. The cylinder here shown is...
