Abstract: 9747. Adams, M. J. April 28. Right to Patent relinquished. Sewage and foul waters, treating; filtering; bacteriological processes.-Relates to apparatus for distributing liquid over filters for sewage and other waters. The apparatus consists in a rotary liquid container carrying distributing arms and entirely floating in liquid, or partially supported thereby. For this purpose the container d carrying the distributing arms e is mounted upon a central axis h in a vessel g filled with water or other liquid, as shown in Fig. 1 (Sheet 1). Similar arrangements are shown in Fig. 1 (Sheet 2), and Fig. 1 (Sheet 4). Alternatively, the ends of the distributing arms may be provided with floats supported by liquid in a circular channel as shown in Fig. 2 (Sheet 1). and Fig. 2 (Sheet 3), and the container may bo mounted on ball -bearings or to float. The revolution of the apparatus may be caused by the exit of the liquid from lateral perforations in the arms, or from pendent pipes on the arms when these are open troughs. As shown in Fig. 1 (Sheet 2), the discharge pipes e play upon paddlewheels d, which serve to distribute the liquid and may also be fitted with pulleys f connected with a pulley on the container b by a rope g for driving the container. The incoming liquid is also used as the propelling force, by causing it to impinge upon suitable blades or wheels as shown, for example in Fig. 1 (Sheet 1), and Fig. 1 (Sheet 4). Or the incoming liquid may be directed into the circular channel and cause a circular movement of the floats therein. In another case the rise and fall of the floats in a tank fitted with a siphon discharge may be caused to operate rope and pulley gearing connected with the central container. In order to effect a greater discharge from those parts of the arms which cover greater areas, the arms are inclined as shown in Fig. 1 (Sheet 1), or arranged with different levels as shown in Fig. 1 (Sheet 4), or the perforations in the arms are arranged spirally to increase the head of liquid along the arms ; or, as shown in Fig. 3 (Sheet 4), the outer parts of the arms may have an independent supply by arms c, and sluices e may be provided for controlling the supply. The supply of liquid to the central container is controlled in some forms by a valve which is opened at each revolution by levers operated by the revolving arms. In the form shown in Fig. 1 (Sheet 5), the supply from the collecting tank is effected by a siphon f. This siphon is put out of action at determined intervals by an auxiliary siphon j, the tank of which is supplied by a regulating cock h. When the siphon j discharges, the pipe k admits air to the siphon f and its action is thereby suspended until the air pipe is again sealed. In a modification, the air pipe of the siphon f dips into the container a to a determined depth. When open troughs are used as distributing-arms, they are transversely corrugated or serrated. The Provisional Specification mentions also distributing- apparatus which travels backwards and forwards over the filter bed.
