    Noones Improvements in Deodorizing and Treating Sewage, $c. substances suitable for filtering purposes, such as sulphate of lime, charcoal, and gravel, through which the main body of the sewage water, as well as that which has been pumped up and passed through the tanks, is filtered by gravitation, and all substances held in suspension are thereby removed. £ These percolating chambers are made movable from the hydrants for the convenience of cleaning, and may be lifted by a windlass with sliding pulley fixed over the mouth of the hydrants. The substance used for filtering, together with the filterings when either or both are of a fertilizing nature, are mixed with the other purified solid matter. The solids when dried as 10 described are pulverized in a mortar or otherwise, and screened to separate the fine from the coarse. I compound the dried purified solid matter of sewage with ammoniacal salts obtained as above described or otherwise in such proportions as may be desirable according to the strength of manure required, also I compound 15 the solid matter of sewage, either with or without the addition of ammoniacal salts, with natural or artificial phosphates or other chemical substances of fertilizing properties, so as to make a compound artificial manure possessing the character required for the particular crop it is intended for. Lastly, my Invention consists in a mechanical arrangement for making the 20 compound before described. This consists of a bin with several compartments which contain the several ingredients to be compounded; in each compartment a roller or chain wheel is fixed, round which an endless chain passes. The chain carries small cups made to hold a fixed amount, and caused to dip into and take a portion of the pulverized contents from the respective compartments 25 up an inclined channel, at the top of which the cups pass over a second chain wheel and becoming inverted discharge their contents into a general receiving chamber; these contents then pass on to a screen or sieve having a recipro¬ cating or shaking motion, and are thus sifted and fall into a bin or receptacle below. The cups are capable of being removed from the chain when cups SO of larger or of smaller capacity are required. The various parts of the foregoing arrangements requiring motive power may be moved by steam, water, or other prime mover, or where the scale of the apparatus is small by animal power or manual labour; and in order to prevent any annoyance or nuisance arising from the process I hermetically 35 seal the whole of the apparatus from the outfall or inlet of the sewer to the discharge of the calciner, where the solid portion of the sewage returns dried and deodorized, and the liquid portion passes purified from the mouth of the hydrants. The foregoing arrangements or parts of them may be employed for deo-
