    Brookes Improvements in Apparatus for Deodorizing Noxious Gases. replenishing the charcoal from time to time is obtained by raising a lid or cover placed at the surface level of the ground, or the tray may be removed through the aperture connecting the charcoal chamber or box with the gully. The bend or branch pipe above mentioned may be divided by a midfeather 5 placed longitudinally therein, the upper passage serving as an air passage for the escape of gas after deodorization, a screen or tray of charcoal being inserted in the air passage for that purpose, the other or lower passage serving to convey water to the drain or sewer as usual; or a tray or screen containing charcoal may be placed in the interior of the gulley or cesspit, which tray or 10 screen is supported above the branch or bend. In the centre of the said tray or screen I introduce a funnel-mouthed pipe, which is supported in a vertical position by the tray or screen above mentioned, the lower end of the said pipe extends to near the bottom of the gully forming a trap. To the surface grating is attached a hopper, which conveys water into the funnel 15 mouth of the vertical pipe above mentioned, and by means of the branch or bend and pipes to the sewer or drain. The gases arising from the sewage matter pass through the charcoal, are deodorized, and escape by the surface grating. The second part of my Invention relates to the deodorizing of gases in their ^0 passage from a sewer or drain by way of the rain pipes, this I effect by removing one of the pipes connecting the rain pipe with the sewer; the pipe so removed I replace with a similar pipe, but provided with a branch and socket (the said branch and socket being in or near the vertical position). In the said socket rests a tray or screen containing charcoal; at the foot of *25 the said rain pipe I place a syphon bend or trap communicating with the pipes leading to the sewer or drain. As the noxious gases ascend the pipes from the sewer or drain they are prevented from ascending the rain pipe before passing through the charcoal by the water (trap) lodging in the syphon bend. The ordinary outlet being cut off the gases ascend the vertical or 30 upright branch, and pass through the charcoal in the tray or screen placed in the socket of the said upright branch (which socket is provided with a lid or cover), from whence they are conveyed by a pipe connecting the socket with the upper part of the syphon bend and escape by the rain pipe. Pipes of an ornamental design may be fixed to buildings specially for the purpose 35 of ventilating sewers and drains by carrying cff the gases after being deodorized as above described. Access to the apparatus for the purpose of replenishing the charcoal from time to time is readily obtained by raising a lid or cover placed level with the footpath or road. Such being the nature of this my said Invention, I will now proceed to
