744,780. Liquid distributer; valves. FULLER, A. July 20, 1954 [April 24, 1953; May 12, 1954], Nos. 11300/63 and 13828/54. Classes 69 (3) and 135. A tank 1 for liquid manure is mounted on wheels and driven by a vehicle, and is connected through a suction pipe 3 and a valve 5 with an airpump on the vehicle. With the valve in one position the pump draws air from the tank and liquid manure is drawn in through a pipe connected at one end to a connector 26 and having its other end immersed in a liquid manure supply. A float switch in the tank automatically cuts off the tank interior from the pump when the liquid therein reaches the required level. Discharge from the tank is effected via a pipe 27, a manually operated valve 29, a distributer chamber 34 and three outlet pipes 36. The outlet pipes, Fig. 3, are connected to the chamber 34 by flexible ducts, and include horizontal parts with oblique outlets about which are arranged plates 37 with side walls 37a. Each outlet is partly closed by a plate 38 pivoted about a pin 40, and pivotally connected at 45 to a pneumatically operated control device. Each device comprises a length of convoluted flexible tubing 42 with its interior connected by piping 56 to the valve 5. The upper ends of the devices are pivotally attached to supports 49, and by adjusting the valve the air pump may communicate with the interiors of the flexible tubes. The partial vacuum created therein contracts the tubes and the plates 38 are completely withdrawn from the outlets to allow a flushing action. By a further valve adjustment the tubes are vented and the plates return to their partly open position. A rod 50 is pivoted to each plate and slides through a support 49, and a compression spring 53 on the rod biases the plate towards the closed position. In a modification, Fig. 5, each discharge pipe has a downwardly extending outlet partly closed by a flat plate 66 mounted at the end of a lever 68 pivoted at 69. The other end of the lever is connected to one end of a pneumatic control device similar to that described which is pivoted at 48 to a support 49. Withdrawal of air from the device causes the withdrawal of the plate 66 from the outlet, and a spring 71 within the tube 42 biases the plate to the partly open position. A canvas shield 72 surrounds each outlet. The float switch, Fig. 2, includes a dome 6 with a detachable cover 7 through which extends a pipe 14 connected to the suction pipe 3. Cylindrical walls 12, 13 extend from the cover, and the outer wall 12 supports a plate 23 and a spider 16 through which passes the spindle 17 of a valve head 18. A float 25 fixed to the spindle moves into the lower part of the wall 12 during the latter part of its upward movement and, in consequence, the tank interior is cut off from the pump and the float is sucked upwardly causing the valve head to move against the wall 13.
