An Improvement in Disinfecting Apparatus.
ANDERS BORCH RECK Civil Engineer 155 Gothersgade Copenhagen Denmark
do hereby declare the nature of this invention to be as follows:-
Before clothing, mattresses etc. are disinfected by steam, and more so after they
have been disinfected, it is much used to place the said articles in drying chambers
heated by tubes, radiators etc., through which is directed the current of steam,
that is blown out of the disinfector during the steaming of the articles. The object
of this invention is to simplify the duties of the attendant and to economize with
steam in such arrangements.
To this effect I place on the tube, that leads the steam from the disinfector to
the heating tubes, a valve having a main opening and a by pass, which valve is
to be kept full open, after steam has been turned on, as long as nothing but air
comes out of the disinfecting apparatus, but which is to be shut off, so that only
the by-pass is open, when all air has been expelled and steam begins to pass through
the exit tube.
If the area of the by-pass opening is duly proportioned both to the steam pressure
kept by hand or by a pressure regulator in the disinfector and to the heating
surface of the tubes in the drying chambers, the attendant will then only have to
shut off the valve, when steam begins to blow through, and no more steam will
pass out of the disinfector into the drying chambers, than will be condensed in the
tubes placed in said chambers.

An Improvement in Disinfecting Apparatus.
I, ANDERS BORCH RECK of Gothersgade 155, Copenhagen, in the Kingdom
of Denmark, Civil 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:-
Before clothing mattresses and the like are disinfected by steam, and more
especially after they have been disinfected, it is customary to place the said
articles in drying chambers heated by tubes, radiators or the like, through
which a current of steam is directed that is blown out of the disinfector during
the steaming of the articles.
The object of this invention is to simplify the duties of the attendant and to
economize the steam in such arrangements.
In order that my invention may be better understood I have represented the
same in the accompanying drawing in which
Figure 1 is a diagrammatic view of the apparatus, and
Figure 2 is a modification of the same.
a is a disinfector 6 is a pipe or tube connecting the same to the heating
tubes t. In the said pipe or tube is arranged a valve having a main

page_text: opening d and a by-pass e, which valve is kept full open, after steam has been
turned on, as long as nothing but air comes from the disinfecting apparatus, but
which is shut off as shown in Figure 1 so that only the by-pass is open, when all
air has been expelled and steam begins to pass through the exit tube.
As shown in Figure 2 I can also arrange in the exit tube b a common stop
valve d, and on a special tube taking the steam from the disinfector a to the
heating tubes a by-pass valve with proper opening e¹.
If the area of the by-pass opening or by-pass valve is duly proportioned both to
the heating surface of the tubes in the drying chambers and to the steam pressure
in the disinfector (this pressure to be controlled by hand or by a pressure
regulator), the attendant will then only have to shut off the main valve, when
steam begins to blow through, then the steam will only find exit through the
by-pass, and no more steam will pass out of the disinfector into the drying chambers,
than will be condensed in the tubes placed in said chambers. In this manner
the drying chambers are heated by the exhaust steam quite automatically without
waste of steam...
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, 1 declare that what I
claim is:-
Improvement in disinfecting apparatus consisting in a by-pass opening or by-pass
valve in the main exhaust tube from the disinfector, this by-pass being placed so
that it gives access for the exhaust steam to heating tubes in a drying chamber,
when the main opening in the exhaust tube has been shut off.
