Improvements in Distributing Apparatus employed in Filtering or Treating Sewage

4694. Lajotte, G. E. E. Feb. 26. Spray-producers and spreaders.-Liquid from a central supply pipe b passes through a trough e and pipe k to the buckets of a wheel g, which turns a roller h and causes it to rotate the apparatus. From the buckets the liquid falls into a trough m connected with a distributing-arm n. The pipe k is fixed by supports l to the shaft f, which also supports the arm n by means of rods s screwthreaded at either end to allow of regulation of the slope of the arm. The arm n has slots o which become smaller towards the end n and slotted sleeves p which can be turned to regulate the openings of the slots o. A gutter r, which is divided into compartments corresponding to the slots o and may have an undulating discharge edge, is situated beneath the arm n, or instead of this arrangement the slots of the distributing-arm may be provided with a fluted sill.
