    Brookes Improvements in Apparatus for Deodorizing Noxious Gases. . ____— •.... ... 1 ■■ ~ - •- lawfully might make, use, exercise, and vend, within the United Kingdom of Great Britain and Ireland, the Channel Islands, and Isle of Man, an Invention for “ Improvements in the Construction and Arrangement of Apparatus and Material for effecting the Deodorizing of Noxious Gases ARISING FROM SEWERS AND DRAINS, AND FOR THE MORE EFFECTUAL VENTILATION OF 5 such Sewers and Drains,” upon the condition (amongst others) that I, the said Edward Brooke, the younger, my executors or administrators, by an instrument in writing under my, or their, or 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 be performed, and cause the same to be filed 10 in the Great Seal Patent Office within six calendar months next and immediately after the date of the said Letters Patent. NOW KNOW YE, that I, the said Edward Brooke, the younger, do hereby declare the nature of my said Invention, and in what manner the same is to be performed, to be particularly described and ascertained in and by 15 the following statement :— This Invention relates to further improvements, in the construction and arrangement of apparatus and material for effecting the deodorizing of noxious gases arising from sewers and drains, and for the more effectual ventilation of such sewers and drains, upon a previous Invention for which Letters Patent 20 were granted to me A.D. 1865, dated September Twenty-fifth, and numbered 2451. The practice heretofore has been to “trap” or prevent the escape of noxious effluvia or gases at the “ gullies or stench traps,” which gullies serve to convey the surface water from the streets to the drains or sewers. My Invention consists, firstly, of a method of constructing and arranging 25 gullies and deodorizing medium in such manner as to deodorize and discharge gases, which I effect as follows :—I construct a gully or cesspit of earthen¬ ware or iron, which by a branch or bend and pipes communicates with the sewer or drain. Upon and communicating with the said branch or bend is a box or chamber, the bottom of which is perforated, and communicates by an SO opening with the upper part of the gully or cesspit. To the interior of said box or chamber is introduced a tray or screen of galvanized wire or iron con¬ taining charcoal (or other deodorant); the noxious gases arising from the sewer or drain pass through the perforated bottom of the chamber or box and through the charcoal, and thence escape through an aperture in the end of 85 the box or chamber to the ordinary surface grating. The gases are pre¬ vented from arriving at the surface grating otherwise than by way of the chamber and box by means of a “ trap ” constructed in the ordinary manner. Access to the tray or screen of charcoal for the purpose of inspecting or
