page_text: I, HENRY HARRIS LAKE, of the firm of Haseltine, Lake & Co., Patent Agents,
Southampton Buildings, in the County of Middlesex, 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 a urinal of novel construction and to its combination
with a heat ventilator.
The object of the said invention is to provide for the removal of noxious gases
from the urinal and to decompose them, so that they shall not enter the apartment
in which the urinal is located. This is accomplished by the mechanism hereinafter
described.
In the accompanying drawing
Figure 1 is an elevation of a trough urinal and a vertical section of a. ventilator
in connection therewith.
Figure 2 is a sectional elevation of the urinal shown in Figure 1 on the line w,
and a face elevation of the ventilator, the said figure also shows, in dotted lines,
how the ventilator may be placed at the back of the urinal.
Figure 3 is a section of the ventilator on the line Z, Figure 1.
Figure 4 is a plan view of a urinal which may be made of burned clay or other
material ordinarily used for bowl urinals.
Figure 5 is a section on the line y Figure 4.
A is the urinal trough, which is formed by a continuation of the back D of an
upwardly projecting chamber of which E is the front plate. The plate E extends
down into the narrow part B of the trough as shown at m in Figures 1, 2, and 5
From the
a free passage being left from the trough A, B into the chamber
chamber the gases are conducted to the heat-ventilator by means of pipes K, L,
the upper part of the chamber being enlarged at J to the proper area for con-
necting the pipes. The ventilator is formed with a small heating chamber g and
a chamber connected with the flue M for the escape' of the decomposed gases.
The pipe L is connected with the casing G H of the heating chamber g at the top

page_text: and the gases pass through the chamber g to a lower opening b in the partition
plate. From the latter opening the gases escape into the chamber f and thence
through the flue M.
A chamber F is formed in the bottom of the ventilator below the opening 6 and
in it is placed a lamp I, or a gas jet to heat the chamber g, to decompose the
noxious gases as they pass down the said chamber.
The correct theory of operation is as follows, that is to say:-The ventilator is
made hot enough to rarefy the air therein, so that a strong downward draft is
caused through the trough A, B, whereby foul gases are taken into the ventilator
and decomposed instead of entering the apartment in which the urinal is located.
The best material to use in the construction of the urinal is that which is
impervious to urine. The ventilator may be of cast or sheet metal, and the
location of the parts may be largely modified to suit various requirements. The
principal features are to draw the gases below the end m of the plate E, then into
the chamber then down and through the chamber g to decompose them by heat,
and then to permit them to escape from_chamber f.
Having now particularly described and ascertained the nature of the said
invention, and in what manner, the same is to be performed, as communicated to
me by my foreign correspondent, I declare that what I claim is :-
A urinal consisting of the trough A contracted at B and partitioned at m by the
plate E, a chamber being formed between the plates E and D, in combination
with suitable connecting pipes L K and a ventilator, consisting of a heating
chamber g having an upper opening a and a lower discharge opening b, a
chamber F, a suitable heater I, a chamber f and a discharge pipe M, as specified.
