    Smith’s Improvements in rTreating Sewage and Ventilating Sewers. sewers is not new, but in addition to such arrangements I further cause steam to flow into and pervade the sewers or culverts, so that by the joint action of the steam and the smoke the sewage waters in the culverts or sewers are disinfected. Having thus stated the nature of my Invention I will proceed more fully to 5 describe the manner of performing the same. Description of the Drawings. » Figure 1 shows a transverse section of a sewer and of a rotatory fan connected therewith by two pipes; Figure 2 shows a longitudinal section of a sewer and rotating fan together with a section of a chimney or shaft; and Figure 3 10 shows a plan in section of the sewer and fan. a, a, is the sewer, which at b, b, has a transverse valve with a float, by which the valve is caused to rise and fall according as the sewage rises and falls within the sewer; c, c, is a rotatory fan in a suitable case. The gases and vapours in one section of a sewer cannot pass the valve so as to get into the next section of the sewer, and by 15 using valves at intervals along a line of sewer such sewer will be divided into sections, and the gases and vapours in each section may be kept separate and be subjected to the action of fire in the following manner :—The gases and vapours in one section of a sewer may be removed from that section of the sewer and forced into the next section of the sewer by a rotating fan or other 20 mechanism, and by having a furnace and shaft or chimney connected with such section of the sewer, either near to or at a distance from the valve, the gas and vapour products may be caused to pass out of the sewer into a closed ash-pit of the fire. Or in place of employing pumping apparatus, each section of a sewer may be provided with a shaft or chimney and furnace. By thus 25 using exhausting apparatus, and by dividing sewers with floating valves, and by admitting steam from steam boilers, and connecting the flues of contiguous buildings with the sewers, smoke and soot will be conveniently introduced into sewers, which mixing with the steam, the same will be more or less con¬ densed and will be mixed with the sewage therein, and such soot and smoke 30 will in combining with the sewage not only tend to deodorize the sewage but render the same more advantageous for agricultural purposes. I would remark that I am aware that it has before been proposed to connect flues of contiguous buildings with sewers, I do not therefore claim the same excepting only when used in combination with my other improvements whereby sewers 35 are divided by floating valves into sections, and such sections are partially exhausted by fans or pumping apparatus, or by chimneys or shafts, as above explained.
