COMPLETE SPECIFICATION.
Improvements in Channels or Receptacles for Sewage and the like
Materials, and in the Method of Deodorizing or Disinfecting the
same.
I, HERMANN STOFFERT of 5 Hermann Strasse, Hamburg in the German
Empire, Merchant, do hereby declare the nature of this invention, and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement:-
This invention relates to receptacles or channels for containing or conveying
Bewage and the like materials, and to a method of deodorizing or disinfecting the
same, and its object is to render such operations cheap, simple and efficient aud,
if desired, continuous.
This invention is carried into effect by passing the deodorizing or other liquid
through the walls of the receptacles or channels which are wholly or partly porous.
The liquid may be passed through the walls by suitable pressure or its passage
may be effected by capillarity.
In order that my invention may be more clearly understood I have appended
hereto a sheet of drawings reference to which is made hereinafter, similar letters
of reference being used to indicate similar parts where they occur in the different
figures.
Figure illustrates a front view and cross section of a channel or gutter
constructed according to this invention.
Figure 2 represents the same channel in cross section.
Figures 3 and 4 represent respectively in front view and cross section a urinal
embodying these improvements.
Figures 5 and 6 shew cross sections of plates from which the receptacles or
channels may be constructed.
As will be seen on referring to the drawings, all parts of the receptacles or
channels with which the sewage or like material comes into contact have double
or hollow walls thus forming a space into which the deodorizing or disinfecting
liquid is led through the pipe or opening d. The outer walls are waterproof or
impenetrable to the passage of a liquid and the inner walls a with which the
sewage comes into contact are of some suitable porous material.
If a channel or receptacle be made in one piece it may be constructed wholly of
porous earthenware or other suitable material and the outer walls be rendered
impervious by glazing or painting. If the outer and inner walls are made
separately they may be of different materials, and their junction may be effected
by means of screws rivets cement or by other well known means or devices.
If, owing either to the defective porosity of the inner walls a or to the viscosity
of the disinfecting fluid a sufficient quantity does not pass then pressure may be
applied by passing the liquid into the space between the walls from a reservoir at a
higher level or the requisite pressure may be applied in any other manner.
The letter c indicates the outlet for the sewage or like material.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. Channels and receptacles for sewage and the like materials constructed and

deodorizing liquid through a porous wall with which the sewage is in contact,
