Year: 1884

page_text: I MAURICE BAUER of the firm of M Bauer & Co of 6 Union Court Chambers
Old Broad Street in the City of London Engineer do, hereby declare the nature of
my Invention for "IMPROVEMENTS IN THE METHOD OF AND IN APPARATUS FOR
DISINFECTING CLOTHES AND FOR OTHER ANALOGOUS PURPOSES " a communication
from Oscar Schimmel Manufacturer of Chemnitz in the Kingdom of Saxony to be
as follows:-
The object of this invention is to effect the perfect disinfection of clothes, linen,
goods, parcels, bales, & by means of a portable apparatus.
The system of disinfection. which is effected with this apparatus consists in the
combination of hot air and steam.
The disinfecting apparatus can. be constructed in various sizes and is composed
of two walls, the floor, the lid, and the front and back walls or ends."
All these parts are composed of iron plates placed a short distance apart, the
space between which plates is filled with a non-conducting material such as
asbestos, slag, wool, or ashes or other analogous material.
The front end wall consists of two doors one above the other, the upper one is
arranged for the purpose of permitting the entrance of a carriage to hold the goods
to be operated upon and the lower door admits a system of steam pipes preferably
fitted with radiating discs mounted on wheels to be placed therein or withdrawn
therefrom for heating the air-All the walls of the apparatus are so constructed
as to be easily taken apart in order to facilitate removal from place to place, and
they can be also as easily reset and placed in position.
Large steam pipes in a coil form are placed upon a separate and distinct frame
provided with wheels and can be removed from the apparatus when required for
cleaning or repairing purposes.-The heat only is utilized from this coil of large
steam pipes the circulation of steam and heat in such pipes being sustained by a
constant supply of steam.

page_text: In addition to the foregoing I fit a number of smaller steam pipes having small
'holes, saw cuts, or other perforations throughout their entire length; to carry
currents of steam into the upper chamber for purposes of disinfection.
This combination, of smaller steam pipes is placed under the floor and alongside
the walls and is as before mentioned pierced over its entire length with small
holes, through which the steam flows quickly and regularly into the interior of
the apparatus. Above the pipe systems a strong frame of wire work is fixed, upon
which large parcels of goods and bales are placed by means of frames which are
attached to the carriage and which may be simultaneously removed from the
apparatus.
"
The upper carriage is mounted on wheels which run upon rails, such rails being
fastened to the walls longitudinally, and the carriage is provided with bars and
hooks upon which the objects to be disinfected are hung, either singly, or in bags
or bales.
At the back of the apparatus is placed a discharging pipe which can be closed
by means of disc or other valves; this pipe serves for discharging steam and hot
air after the disinfection process is over.-Other openings are provided through
which fresh air enters when necessary, but these openings are closed while the
disinfection process is being carried on.
The disinfection process is effected as follows;--
After opening the door of the apparatus the goods carriage is drawn out and
this, as well as the wire work, is then laden with the objects to be disinfected.
This being done the carriage is pushed back into the apparatus, the door, the air
holes, and the valves, are then closed and steam is turned on to the large steam
pipes and so continued until the thermometer affixed in the interior of the
apparatus, (the scale of which however can be read from the outside,) indicates
from 100 to 110 degrees, Centigrade.-When this temperature is reached the steam
is turned on to the smaller pipe system which admits the steam directly into the
interior of the apparatus and so continued until a temperature of from 125 to
130 degrees, Centigrade, is obtained; this temperature is kept up for half an hour
by the same means; the steam is then shut off from the smaller steam pipes, and
the air entrance, openings and the valves in the discharge pipe are opened. After
a lapse of about fifteen minutes during which time the larger pipe system is
gradually closed to the steam, the drying process of the disinfected objects is
completed and at the same time the vapours developed and formed are carried
away by the strong circulation of the air-current; the persons attending the dis-
infecting apparatus may 'then open the door. and take out the carriage, remove
the disinfected objects and goods without incurring any risk or danger to their
bealth.

I MAURICE BAUER of the firm of M: Bauer & Coy of 8. Union Court formerly
6 Union Court Chambers Old Broad Street in the City of London, Engineer,
do hereby declare the nature of my said Invention for IMPROVEMENTS IN THE
METHOD OF AND IN APPARATUS FOR DISINFECTING CLOTHES AND FOR OTHER
ANALOGOUS PURPOSES "
a communication from Oscar Schimmel, Manufacturer, of
• Chemnitz in the Kingdom of Saxony, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:-
The object of this invention is to effect the perfect disinfection of clothes,, linen,
goods, parcels, bales, and other articles by means of steam and hot air applied to
the same in the apparatus hereinafter described.
IT
And in order that my said invention may be particularly described and ascer-
tained, reference is hereby made to the "accompanying drawings, in which three
forms of the apparatus are described; and in which similar letters of reference
indicate corresponding parts.
Fig 1 is a sectional elevation, and
Fig: 2 is a transverse or horizontal section of one form of the invention. a. a is
a circular wall, built of masonry or other suitable non-conducting material. In
this wall the iron cylinder a¹ is fitted, and is covered by an air tight lid & formed
hollow and filled with sawdust, or other suitable non-conducting material. This
lid is fixed in position by the brackets and screws 8 8. At the bottom of the
cylinder the double set of pipes k. k are fitted. These pipes are connected together
by junctions, as shewn in Fig 2, and are supplied with steam by the pipe k¹, to
which a stop valve is 'fitted at k².
The pipes have a number of annular gills to heat the air in the chamber.
The condensed water from these pipes is conducted by the pipe to the receiver c,
fitted with an overflow pipe c¹. The lower end of the chamber is also fitted with
the pipe b, to drain off condensed water. A valve is fitted to the box o to admit
air, and an eduction pipe m with a throttle valve m¹, is also fitted for the escape
of air, is a coil of perforated pipe, fed with steam by the pipe and regulated by
the stop, valve 12 by means of which steam may be admitted to the chamber.
A Thermometer is fitted at t to indicate the temperature of the interior. The lid d
is fitted with differential pullies f for lifting the same. To the lid is attached a
moveable perforated cylinder h with hooks r sliding on cross, bars, for sustaining
the articles to be disinfected..
Fig: 3 is a sectional elevation, and Fig 4 a transverse or horizontal section of
another form of the invention, a. a are the outer walls, and a¹ a³ are double
cylinders leaving a space or jacket a³ between the same. These cylinders have
curved bottoms as shewn. The jacket a³ is supplied with steam by the pipe k³ to
heat the cylinder. The cylinder is supported by the brackets 8 to which the screw
brackets 8181 are fitted to hold the lid d securely and steam tight. p is a grating
through which the air enters to the space a*, which air gains access, by means of

page_text: the pipe o and stop cock o¹ to the interior of the chamber. By means of the
pipe and coil steam is led into the interior when necessary. c and c¹ are drain
pipes for draining the condensed water from the cylinder and jacket. m is the
eduction pipe, and m¹ is a regulating valve for withdrawing air from the chamber,
with the aid of a steam jet, supplied by the pipe k. .h¹ is a grating, on which some
of the articles to be disinfected may be placed.
:
In figs 1 and 2 the air is heated by means of the pipe k; and in Figs 3 and 4
the heating of the internal air is effected by means of the steam jacket a³.
Figs: 5. 6. 7 and 8 represent a rectangular form of my invention; Fig 5 being
a longitudinal sectional elevation, Fig. 6 a horizontal section; Fig 7 a transverse
elevation, and Fig: 8 a front elevation.
In this form of the apparatus the heating of the air is effected by means of the
tubes (as in Figs: 1 and 2). The front of the chamber consists of two doors a a
one above the other, the upper door as being used for the purpose of passing the
carriage h in and out, and the lower door as for the purpose of removing the heating
pipes when necessary oo are openings for the entrance of fresh air, when necessary
to admit the same. The walls are formed of iron plates with non-conducting
material placed between the plates and the carriage h and set of pipes / are fitted
with wheels or rollers g g as shewn, sustained by rails on which they run. All the
walls of the apparatus shewn in Figs 5. 6. 7 and 8 are arranged so as to be readily
taken apart and put together again, in order to facilitate removal from place to
place.
