George Henry Leane, 21 Queen Anne's Gate, Westminster S,W, Civil Engineer, do hereby declare the nature of my invention for Improvements in Apparatus FOR THE CONTINUOUS, OR INTERMITTENT FILTRATION OF SEWAGE, AND FOR LIKE PURPOSES, and in what manner the same is to be performed, to be particularly 5 described and ascertained in and by the following statement:— My Invention consists in improvements in apparatus for the continuous, or inter¬ mittent filtration of sewage, and for like purposes, and is carried out as follows— In a filter tank, which may be of any required shape; or dimensions, I place a series of vertical slides, in such a manner as that all the water, sewage or other 10 liquid, to be filtered must pass through the whole series of such slides, (a series in fact forming a filter in sections) which may consist of any required number. For the purpose of describing my improvements I have shewn upon the drawing annexed hereto, a series of five filter slides, and two screens. Fig. 1 is a vertical section of filter, upon line A B. 15 Fig, 2 is a plan, shewing one arrangement of filter for sewage, or other like purposes. The sewage, or other liquid to be filtered, first passes through the screens a, 6, which consist of wire netting of suitable size for the purpose; thence in rotation through the filters c, d, e, /, g, of which c, and d, may be of coarser material 20 (carbon or other filtering medium) than the others, while g, may be of the finest description possible, and may be covered upon the inner side with asbestos, or other filtering cloth. I prefer to fill the filter frames (hereinafter described more fully in detail) with carbon of a porous nature, but they may be filled with any other loose filtering 25 medium, or for water filtration only may be constructed of porous carbon slabs. The slides as well as the screens; are interchangeable, and can be made of any desired size. The frames of the slides are composed of timber (I find that “ Jarrah timber is especially suitable for the purpose) but iron, or any other suit¬ able substance can be used if desirable. These frames are covered on both sides by 30 wire netting as at, h, or other open material capable of retaining the carbon (or other filtering medium employed) in position, and are fitted into grooves prepared [Price Gd]
