Abstract: 22,052. Briscoe, J. T. Oct. 6. Spray-producers and spreaders.-A tank or trough from which the sewage &c. is passed intermittently to the distributing-arms forms part of the rotary or travelling portion of a moving distributor. With the apparatus shown in Fig. 2, the liquid is supplied by the pipe A' to the tank E. When the tank E is sufficiently full, the liquid overflows into a floating bucket G. A float F within the bucket is connected to it by cords over pulleys, or by equivalent means, so that when the bucket is filled.both move together and open the valve V. Liquid then flows through the valve-box H to the arms I, the apparatus being rotated on bearings C, D. On the emptying of the tank E, the bucket G is emptied by an automatic valve and the bucket and float close the valve V. Overflow arms J, connected by pipes K with cocks K<1> to the arms I, are attached to the tank E. In a modification, these arms J are bent down nearly to the level of the arms I. Rigidity is secured by means of braces and struts L, M with adjusting-screws L<1>. A siphon may replace the valve and bucket. In modified apparatus, the tank E is replaced by a circular trough, each distributing-arm having its own supply siphon. Fig. 4 shows an arrangement in which a tank E surrounds a central supply pipe A<1>. As shown at the right - hand side of the Figure, the tank E is filled by a pipe sealed at its lower end. The discharge valve V is operated by the overflow passing into a bucket G in a compartment of the tank E. A float F opens the valve of the bucket when the tank E is empty. The valve of the compartment is operated by a floating airdome. As shown on the left - hand side of the Figure, the tank E is supplied by a siphon 2 and discharged by a siphon G<1>. The liquid may be supplied to the tank E by means of a mushroom feed, or through pipes or nozzles fitted with ball valves or cocks actuated by the level of liquid in the tank. In other modifications, the arrangement is shown in connexion with rotary or travelling distributors taking the form of a water-wheel. A trough E extends along the length of the waterwheel, and is discharged either directly on to the buckets of the wheel or to a pipe which feeds the wheel internally. In the case of travelling distributors, supply pipes are fixed at intervals depending on the capacity of the trough E. The distributor opens the cock of such a pipe as it approaches, and the trough E is then filled. The discharge of the trough E moves the distributor, which closes the cock as it leaves. The pressure of the liquid in the trough distributing-arms is maintained by means of heavy plates x, Fig. 8, resting on seatings Y of rubber, leather, felt, or the like, attached to the plate x or to seatings W. The plates may fit into one another at their ends, jackscrews or clamps tightening against the sides of the trough being placed across the tops of the joints. The plates have handles x<1>. Another part of the invention relates to the use of plates in connexion with the holes or slots of distributing-arms so as to form nozzles or a continuous nozzle to spray the liquid. The edges of the orifices are bossed or have frames with planed edges and grooves to receive the plates. The plates may be fixed in position by means of wedges. Instead of the wedges, turn-buttons, clamps, bolts, set-screws, or the like may be used. Fig. 9 shows an arrangement in which plates Q, Q<1> are fixed over the orifice 0 by means of a clamp S<1> and screws S<2>. Fig. 11 shows plates Q, Q<1> of buckled or bellied shape used in connexion with a circular orifice O.
