Improvements in Apparatus for Deodorizing and Flushing Urinals
and the like.
I, WILHELM BEETZ of 18 Girtnergasse Vienna Austria Gentleman, do hereby
declare the nature of this invention to be as follows:-
This invention relates, to a deodorizing and flushing syphon for urinals in which
the urine is covered by a layer of oil for the purpose of thoroughly deodorizing
the urinal and of allowing this urine to run off by hydrostatic pressure in
accordance with the principle of communicating vases, the oil or oil mixture used
having the property of destroying all polluting germs of disinfecting urine and
of adhering to the syphon walls in consequence of its particular adhesive power, so
that the urine may not come into contact with the said walls.
The syphon may be made of any suitable metal, glass, porcelain, stoneware,
cement, or the like and may be applied alone or as a part of another device to a
basin for instance.
This syphon consists of a receptacle, the outlet of which is connected with a
discharge or sewer pipe and which is provided with an outer pipe surmounted by a
lid or cover of larger diameter and with a central outlet pipe this lid being furnished
with a number of openings while the above pipes are also furnished at their upper
extremity with suitable openings. For use the syphon is first filled with any
suitable liquid, preferably water which is poured upon the lid aforesaid whence it
passes through the openings in the latter into the syphon and fills the spaces or
intervals between the inner and outer pipes and between the latter and the
receptacle. When the liquor has settled, oil is poured thereon so as to form a
layer at least one centimeter thick.
In urinals which are supplied with this syphon the urine will run into the
latter through the holes in the lid and as it runs over through the openings in the
central pipe will expel a quantity of water or urine equal to that which has entered
through the lid and as oil is lighter than water and urine, it will float as a layer
upon the heavier liquid and act as a good deodorizer. When that part of the
urinal which is contaminated with urine is daily cleaned not with water, but by
rubbing it with a hard brush dipped in oil, the latter has the property of preventing
the urine from adhering and hence of expelling it, in à measure, and compelling it
to disappear into the syphon below the layer of oil. As the air cannot get access
to the urine, the latter cannot be decomposed and hence foul gasses and odours
cannot arise, so that the urinal remains thoroughly odourless, nearly all the oils
are emulsionned by the urine, after a short time, and hence become inactive, thick,
and clogs the syphon. Other oils such as clear petroleum, benzine and the like are
dangerous because of their inflammability.
Repeated experiments have proved that the most suitable substances was the
residium from the distillation of petroleum, having specific gravity of over 890 to
which is added 25% of coal tar oil for preference anthracene oil as well as --- of
a solution of corrosive sublimate for disinfecting purposes. Blue oil could also be
employed.
.
This oily compound is preferably prepared in the following manner. The
residium of the distillation of petroleum and particularly that which has a specific
gravity of over 890 and which is distilled off, at a temperature of over 350° C.
is first heated at a temperature of 300° C. until no more froth is formed in order to
drive the water out, and enable it to absorbe and thoroughly dissolve a 0001 % of
corrosive sublimate solution, so that after cooling this sublimate, may not be
precipitated from the oily mixture. After cooling 25% of coal tar oil for preference

page_text: anthracene oil is incorporated, with the said mixture, which is heated to about
140° C. and, forthwith rapidly cooled. This oily compound has besides the
advantage of acting as a disinfectant, the peculiar property tenaciously adhering
to the syphon walls whereby the urine is fully expelled from these walls.

Improvements in Apparatus for Deodorizing and Flushing Urinals
and the like.
I, WILHELM BEETZ, of III Gaertnerstrasse No. 18, Vienna, Austria,
Gentleman, 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 deodorizing and flushing siphon for urinals in which
the urine is covered by a layer of oil for the purpose of thoroughly deodorizing
the urinal and of allowing the urine to run off by hydrostatic pressure. The oil or
oil mixture used has the property of destroying all noxious germs and of disinfecting
urine; also, being of very adhesive character it covers the interior surface of the
siphon, preventing the urine from coming in contact with the said surface.
The siphon, represented in section in the accompanying drawing, may be made
of any suitable metal, glass, porcelain, stoneware, cement or the like, and may be
used alone or in connection with a sink, basin or the like.
It consists of a receptacle a the outlet 6 of which leads to a drain or sewer. A
cylinder c projects down from the cover d and surrounds a central outlet pipe e.
Through the lid d are openings d' d' and through the lower edge of c and the upper
edge of e are openings c¹ and e', respectively.
The siphon is first filled with any suitable liquid, preferably water poured upon
the lid d'and passing through the openings d' a¹.
When the liquid has settled, oil is poured in so as to form a layer of about half
an inch in thickness. Afterwards, urine entering by the holes d¹ descends through
the layer of oil f, displacing an equivalent volume of liquid which escapes by the
openings e¹, the oil continuing to float as a layer upon the heavier liquid and to
act as a deodorizer and to prevent access of air to the urine or escape of gases
from it.
If the lid d passages d¹ and upper part of the siphon are daily cleaned not with
water, but by rubbing them with a hard brush dipped in oil, urine is prevented
from adhering to those parts and must therefore descend into the siphon below the
layer of oil, and, as no gases escape, the urinal remains quite inodorous.
Many oils are after a time brought by urine into condition of emulsion and thus
become thick and inactive clogging the siphon.
Other oils such as pure petroleum, benzine, and the like are dangerous because of
their inflammability.
Experiments have proved that a suitable substance for use as described is the
residue from the distillation of petroleum, having specific gravity of over 0-890 to
which is added 25 per cent. of coal tar oil, preferably anthracene oil, along
with about one thousandth per cent. of a solution of corrosive sublimate for
disinfecting.
This oily compound is preferably prepared in the following manner: The residue
of the distillation of petroleum and particularly that which has a specific gravity
over 0.890 and which is distilled off, at a temperature of over 350° C., is first heated
to a temperature of 300° C., until no more froth is formed, in order to drive the
water out, and enable it to absorb and thoroughly dissolve about one thousandth

page_text: per cent. of corrosive sublimate solution, so that after cooling this sublimate may
not be precipitated from the oily mixture.
After cooling, 25 per cent. of coal tar oil, preferably anthracene oil, is incorporated
with the said mixture which is heated to about 100° C. and then rapidly cooled.
This oily compound, beside acting as a disinfectant, has the peculiar property of
tenaciously adhering to the siphon walls, causing urine to be expelled from their
surfaces.
Having now particularly described and ascertained the nature of this inven--
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. An oil siphon for urinals and the like, consisting of a receptacle a, a cylinder c
and lid d and a central outlet pipe e, the lid and cylinder and pipe having suitable
openings arranged and operating in conjunction with a layer of oil, substantially as
and for the purpose set forth.
2. For use in an oil siphon such as is above referred to, of an oily compound.
produced substantially as described.
