A New or Improved Disinfecting Apparatus.
I FRIEDRICH ANDRE of Hildesheim Hanover Engineer 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 has for its object a disinfecting apparatus which acts at the same
time as a steam generator.
The invention consists of an upper part enclosing a carriage and of a lower
part and differs from other known disinfecting apparatus in so far that it does not
require a special steam generator.
The apparatus may be heated by means of coal or coke, steam at a temperature
of from about 100 to 102 C. being generated within an hour. The consumption of
coal is very slight 18 to 20 kil. of coke or coal or thereabouts being only required
for a charge of about 1 to 2 hours duration.
It is obvious that by dispensing with a special steam generator the cost of
manufacture of the apparatus will be considerably reduced so that even small
parishes corporations or parties of small means will be able to procure such an
apparatus.
The invention is shown in the accompanying drawings in which
Figure 1 is a longitudinal section thereof on line A B G H of Figure 2.
Figure 2 is a cross section of the same on line C D of Figure 1.
Figure 3 is a horizontal section on line E F of Figure 1.
Figure 4 is a side view of the apparatus the masonry being removed.
Figure 5 is a front end view of the boiler.
The apparatus consists of a boiler O which is walled in when set up and the
lower part of which serves as a water chamber i.e. as a steam generator while the
upper party is supplied with the articles or materials required to be disinfected
such as bedding washing et cetera.
The upper part is closed on both sides by doors turning on hinges and secured
air tight by means of screws. In this part is arranged a track formed of angle
irons upon which a carriage e running on wheels can be conveniently pushed in
and out.
To maintain the water at a uniform height the feed water is supplied to the
lower part through a funnel a arranged on, one side this water entering first the
heater and then the boiler wherein it is heated by the fire gases which ascend
from below and pass along the tubes c on their way to the flue d and the chimney-
steam being thus generated at a temperature of about 102 C. at the outside.
In the upper part of the flue is arranged a damper f which allows when opened
the greatest part of the heating gases to be conveyed to the pipes g arranged above
the tubes c and used for drying purposes while by opening a small valve h
adapted to the front end of the boiler fresh air is admitted for cooling and drying
purposes.
Although the construction is such that even after closing the valve i arranged
in the tubular neck on the top of the boiler the temperature of the steam will
not exceed about 102 C. yet a safety valve k is arranged as a further precaution
in the upper wall of the boiler while the thermometer / indicates the temperature
inside the latter.
The disinfecting process is carried out in the following manner :-
As soon as the washing bedding and other articles which are either suspended
or heaped up in the carriage have been subjected for a period of from to 1 hour
or thereabouts to a temperature of about 102 C. the damper and the valves h

page_text: and i are opened whereupon the greatest part of the heat passes through the pipe g
while fresh and dry air is admitted.
•
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed declare that
what I claim is:-
A combined disinfecting apparatus and steam generator having a boiler the
upper part of which is closed air tight by lateral doors and encloses a truck e
running on wheels in and out thereof and designed to receive articles or materials
to be disinfected which are left for a period of from to 1 hour or thereabouts in
the steam generated at about 102 C. in the lower part a dried by the pipes y after
the valves hi have been opened and cooled by the fresh air admitted all substan-
tially in the manner and for the purpose hereinbefore described and illustrated in
the drawings hereunto annexed.
Dated this 25th day of June 1891.
