    FaJilman's Improved Apparatus for Treating Sewage, fyc. my executors, administrators, and assigns, should at any time agree with, and no others, from time to time and at all times thereafter during the term therein expressed, should and lawfully might make, use, exercise, and vend, within the United Kingdom of Great Britain 5 and Ireland, the Channel Islands, and Isle of Man, an Invention for “ Improved Apparatus for Disinfecting and Collecting Fcecal Matters, Sewage, and Manufacturing Refuse/’ upon the condition (amongst others) that I, the said Brandis Jules Pahlman, my executors or administrators, by an instrument in writing under my, or their, or 10 one of their hands and seals, should particularly describe and ascertain the nature of the said Invention, and in what manner the same was to he performed, and cause the same to he tiled in the Great Seal Patent Office within six calendar months next and immediately after the date of the said Letters Patent. 15 NOW KNOW YE, that I, the said Brandis Jules Pahlman, do hereby declare the nature of my said Invention, and in what manner the same is to he performed, to he particularly described and ascertained in and by the following statement, that is to say:— This Invention relates to improved apparatus for the disinfection of 20 foecal matters and substances discharged from the sewers of towns, or from the outlet pipes of manufactories and industrial works, and consists of a reservoir of any required size containing a moveable horizontal tray or partition made of wire, cloth, or of perforated plates of zinc or other metal or material, the tray or partition being placed within the reservoir 25 so as to divide it into two compartments, the upper one for containing disinfecting materials, and the lower one for receiving the sediment or solid matters contained in the sewage. The matters discharged fiom the sewers or other places are made to pass through a basin or other shaped funnel into the lower compartment of the reservoir, and the liquid 30 portion by the effect of the pressure from the flow of the sewage rises through the disinfecting materials and passes off through an outlet or delivery pipe. These improvements will be clearly understood by referring to the figures and letters on the accompanying Sheet of Drawings, in which 35 Figs. 1 and 2 are end and front elevations of the apparatus arranged to receive the sewage from a branch sewer.
