Improvements in Steam Disinfecting and like Apparatus.
1, ANDERS BORCH RECK, of Gothersgade 155, Copenhagen, 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:-
By stationary steam disinfecting apparatus for disinfecting clothing, bedding
articles, and the like by steam it is often very important that the whole apparatus,
disinfecting chamber and boiler combined takes as little room as possible, and that
they may be transported in a complete state, so that the erection of the whole
apparatus only consists in connecting it with a chimney
More so is a compact
airangement of disinfecting chamber and boiler important by apparatus, that are
destined to be transported from one place to another on its own wheels (portable
apparatus).
It has been tried to solve this problem in different manners, but the forms
offered at present are not without defects. Either they are only adapted to be
worked at about atmospheric pressure of the steam, being thus rather slow in
their action, or they are costly to make, or they can not be built with doors in
both ends, because the boilei has to be placed at one end of the disinfecting
chamber. The latter defect is very great, as in this case the disinfecting chamber
must be filled and emptied from the same place, so that the disinfected articles are
exposed to being infected again when taken out My construction avoids all the
liere mentioned defects, it can be built to work at any steam pressure, it is not
costly to make, and the disinfector can have doors in both ends. This is obtained
by dividing the boiler into two receptacles, an upper one and a lower onc. The
lower is acted upon by the fire and placed under the disinfecting chamber. The
upper receptacle, that serves for separating water and steam is ordinarily placed
directly over the disinfecting chamber Pipes connect the two receptacles so
that the steam developed in the lower receptacle freely mounts into the upper
receptacle, while the water brought along with the steam to the upper receptacle
fiecly can return from here to the lower
In my drawing Figure 1 and Figure 2 represent two different vertical sections
through my disinfecting apparatus. d is the disinfecting chamber in which the articles
are disinfected by steam a and bare the two receptacles, which in connection
with the two pipes r₁ and r₂ form the boiler. 8 is the steam pipe from the boiler
to the disinfecting chamber. t is an exhaust cock on the disinfecting chamber,
through which the au can be blown out of the said chamber. c 18 the smoke tube
from the boiler.
The apparatus will act in the following manner -
When a fire is built on the grate g of the lower receptacle a, the water in this
will be heated and partly be transformed to steam, this goes to the receptacle >>
though the pipe r. The water carried along with steam will sink down again
to a through the pipe, while the steam through the valve on the pipes can be
led into the disinfecting chamber d, where it first expels the air through t, and
then acts upon the clothing and other articles laid into the chamber.
Dotted lines indicate on the diawing how the apparatus can be provided with
axle e wheel and poles when it is wished to render it easily portable It will
be seen that on account of the construction of the apparatus it is easy to lend

page_text: the axle from one side of the apparatus to the other between the disinfecting
chamber and the lower receptacle a, while on the greater part of similar apparatus
it is necessary to let the axle describe a much larger bow downwards.
If it is wished to provide the disinfecting chamber with apparatus for drying the
articles by diy hot air after the disinfecting, this can easily be done by surrounding
the receptacle a with a jacket n provided in the bottom with openings o through
which the an can pass into the interval between the receptacle a and the jacket
for being heated here This heated air can then be given access into the interior
of the disinfecting chamber through the valves k moved by handles/
The damp
air can be given exit from the disinfecting chamber through another valve m
either as shown in the drawing direct into the open air or to an au pipe, which
can be made to draw better, when it is either connected with the chimney of the
apparatus or provided with a steam ejector a a are the doors or ends of the
disinfecting chamber d.
Having now particularly described and ascertained the nature of this inveu-
tion and in what manner the same 18 to be performed I declare that what la
claim is
1. Steam disinfecting apparatus where the boiler necessary for developing
steam is divided into two receptacles, of which the lower a fitted with fireplace 18
placed under the disinfecting chamber d aud through the pipes" and ", connected
with the upper in such a manner that the steam developed in the lower
receptacle a freely can mount into the upper b, while at the same time the water
called along with the steam returns to the lower a, and the steam separated from
the water can go in dry state from the upper receptacle to the disinfecting
chamber, as set forth
2 In apparatus as set forth in Claim 1, the arrangement that between the
disinfecting chamber d and the receptacle a placed under it and forming the lower
part of the boiler, is fixed an axle e ou which are fitted wheels, as described
3 In apparatus as described in Claim 1, the arrangement that the lower
receptacle a is surrounded by a jacket n provided with openings o for the entrance
of an into the space between receptacle and jacket, while the disinfecting chamber
13 provided with valves k, through which this air can be led into the disinfecting
chamber, as set forth
