    Dixon’s Apparatus for Disinfecting and Deodorising Sewer Gas. strands 6 placed in and falling oyer its sides on to tlie flannel or other porous material 4, which is thus always kept saturated. The tank 2 may he made of iron, zinc, or earthenware (as may also the tank 5), and it is kept in position by projecting flanges 12 resting on fillets 13 of the frame 1; the tanks are thus arranged for ready removal 5 or cleaning. The trap or ventilator 1 may be made of iron, stone, wood, or brick in cement; it is divided by a partition 7 into two portions 8, 9, one of which 8 communicates directly with the sewer or drain, and the other of which 9 opens to the air through a grating 10, which is hinged to the 10 frame 1 in the usual manner. The upper part of the division 7 is fitted with a frame 11, covered with canvas, wire, or zinc gauze, or with any other material suitable for preventing dust or dirt entering by the grating 10 having access to the flannel 4, and checking its proper action. The road dirt, stones, and surface water which fall through the 15 grating 10 accumulate in the compartment 9, which is immediately thereunder, and can be readily removed therefrom when necessary. Or the surface water may be carried from the comparrment 9 into the sewer or drain beneath the tank 2 either by an ordinary trapped tube or spring tap. If required a narrow gutter may also be run round inside of the 20 upper edge of the compartment 8, and leading into the compartment 9 so as to carry away thereinto any surface water which may possibly obtain access to the compartment 8, and prevent its diluting the liquid therein. The liquid disinfectant or deodorizer is poured into the tanks 2 and 5 25* after lifting the grating 10, the solid portion 14 of which when closed covers both tanks, and prevents any dust or other extraneous matter obtaining access thereto. On the accompanying Sheet of Drawings Figure 1 represents a plan of the grating 10 and cover!; Figure 2, a plan shewing the tank 5; 30 Figure 3, a plan shewing the tank 2 ; Figure 4, a cross section; Figure 5, a longitudinal section; and Figure 6, a section of the compartment 9. Having now particularly described and ascertained the nature and object of my said Invention, together with the manner in which the same is to be or may be performed or carried into practical effect, I 35 would remark in conclusion that I claim as my Invention, the disin¬ fecting and deodorizing of the gases emitted at the ventilating shafts or
