"Improvements in and relating to Disinfecting Apparatus."
I, WILLIAM EDWIN THURSFIELD of Gumpoldskirchen, near Vienna, in the
Empire of Austria, Civil Engineer, do hereby declare the nature of this invention
to be as follows:
The improvements relate to the construction of stationary and portable
disinfectors, either vertical or horizontal, for purifying wearing apparel, bedding
and the like, by passing through them a current of live steam from any existing
boiler under pressure, without the necessity of reducing or safety valves.
The apparatus consists of a double cylindrical vessel with a suitable arrange-
ment to prevent automatically any pressure in excess of that required to ensure
a constant circulation of live steam through every part.
The steam is taken from any existing boiler working under sufficient pressure
to ensure a current.
The accompanying drawings shew a stationary apparatus in Figure 1, in a
longitudinal, and in Figure 2, in a cross section.
A. A. is the outside shell of a double cylindrical vessel.
B. B. is the inside shell of a double cylindrical vessel, forming the disinfecting
chamber X surrounded by a current of live steam which, after filling the annular
space between A. A. and B. B. enters the chamber X from above, and escapes from
below.
C is a steam inlet pipe connected with any existing boiler under pressure.
d. d. are openings in the upper portion of the cylinder B. B. for the inlet of
live steam into the disinfecting chamber X.
f.f. are openings in the upper portion of the collector E for the outlet of the
waste steam.
E. which forms the floor of the disinfecting chamber X is the collector for
the waste steam.
G. is the outlet tube connecting the collector E. with the open air fitted with a
control thermometer for registering the temperature of the escaping steam.
H is a chamber attached to the lowest part of the outside shell A. A. whose
upper half being above the inlet C. acts as a distributor for the entering steam
whereas the lower part being carried to a sufficient depth below the inlet C. acts
as a collector of the condensation water formed by contact of the steam with the
outer cylinder A. A.
K. is an open stand pipe connected with the chamber H. at its base and lead
up outside the apparatus preferably to a height somewhat less than the latter to
act as a safety valve in case of any excess of pressure from the boiler.
The column of condensation water which collects in the base of this open stand
pipe prevents any escape of steam through the same.
L. is a cock at the base of the chamber H. for regulating the flow of the
condensation water.
The steam generated in any existing boiler working under pressure is lead by
means of the inlet pipe C. into the upper part of the chamber H. is distributed

page_text: hence upwards between the cylinder A. A. and B. B. enters the disinfecting
chamber X. through the openings d. d. and after passing through the contents
escapes through the openings f. f. into the waste steam collector E. and thence
through the tube G. into the open air.
The column of water collecting in the chamber H, and the open stand pipe K.
is regulated by the outflow cock L.
The advantages of this disinfecting apparatus are:-
That the same can be adapted in any steam ships, hospitals, barracks, prisons,
baths, wash houses and the like where steam in any form is used, whether the
pressure be high or low.
The material used in its construction can be much weaker and consequently
cheaper than that hitherto employed for this purpose, and costly fittings such as
reducing and safety valves, as well as working expenses of skilled attendants
where steam under pressure is used can be dispensed with.
The invention is not confined to the exact construction of the apparatus as
shewn in the drawings; the apparatus may be constructed with two doors for
charging and discharging at opposite ends, either stationary, as shewn, or on
wheels, either vertical or horizontal.

"Improvements in and relating to Disinfecting Apparatus."
I, WILLIAM EDWIN THURSFIELD of Gumpoldskirchen, near Vienna, in the
Empire of Austria, 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.
The improvements relate to the construction of stationary and portable
Disinfectors, either vertical or horizontal, for purifying wearing apparel, bedding
and the like, by passing through them a current of live steam from any existing
boiler under pressure, without the necessity of reducing or safety valves.
The apparatus consists of a double. Cylindrical Vessel with a suitable arrange-
ment to prevent automatically any pressure in excess of that required to ensure
a constant circulation of live steam through every part.
The steam is taken from any existing boiler working under sufficient pressure
to ensure a current.
Referring to the drawings, filed with the Provisional specification, these shew
a stationary apparatus in Fig 1 in a longitudinal, and in Fig 2 in a cross section..
A. A. is the outside shell of a double cylindrical vessel. B. B. is the inside shell
of a double cylindrical vessel forming the disinfecting chamber X surrounded by
a current of live steam which, after filling the annular space between A. A.
and B. B. enters the chamber X from above, and escapes from below. C is a
steam inlet pipe connected with any existing boiler under pressure.
d. d. are openings in the upper portion of the cylinder B. B. for the inlet of
live steam into the disinfecting chamber X.
f.f. are openings in the upper portion of the collector E for the outlet of the
waste steam.
E. which forms the floor of the disinfecting chamber X is the collector for
the waste, steam.

page_text: G. is the outlet tube connecting the collector E. with the open air fitted with a
control thermometer for registering the temperature of the escaping steam.
His a chamber attached to the lowest part of the outside shell. A. A. whose
upper half being above the inlet C. acts as a distributor for the entering steam
whereas the lower part being carried to a sufficient depth below the inlet C. acts
as a collector of the condensation water formed by contact of the steam with the
outer cylinder A. A.
K. is an open stand pipe connected with the chamber H. at its base and led
up outside the apparatus preferably to a height somewhat less than the latter to
act as a safety valve in case of any excess of pressure from the boiler.
The column of condensation water which collects in the base of this open stand
pipe prevents any escape of steam through the same.
L. is a cock at the base of the chamber H. for regulating the outflow of the
condensation water.
The steam generated in any existing boiler working under pressure is lead by
means of the inlet pipe C into the upper part of the chamber H. is distributed
hence upwards between the Cylinder A. A. and B. B. enters the disinfecting
chamber X. through the openings d. d. and after passing through the contents
escapes through the openings d. d. and after passing through the contents escapes
through the openings f. f. into the waste steam collector E. and thence through
the tube G. into the open air.
The column of water collecting in the chamber H, and the open stand pipe K
is regulated by the outflow cock L.
The advantages of this disinfecting apparatus are that the same can be adopted
in any Steam Ships, Hospitals, Barracks, Prisons, Baths, Wash-houses etc where
steam in any form is used whether the pressure be high or low.
The material used in its construction can be much weaker and consequently
cheaper than that hitherto employed for this purpose, and costly fittings such as
reducing and safety valves, as well as working expenses of skilled attendants
where steam under pressure is used can be dispensed with.
The Invention is not confined to the exact construction of the apparatus as
shewn in the drawings; the apparatus may be constructed with two doors for
charging and discharging at opposite ends, either stationary, as shewn, or on
wheels, either vertical or horizontal.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed, I declare that what
I claim is:
A double cylindrical vessel for disinfecting wearing apparel, bedding and the
like A. A. B. B. with a steam inlet C. A steam distributing and condensation
water collecting chamber H steam inlet holes . d. and steam outlet holes f. f.
in the disinfecting chamber X a waste steam collector E an outlet tube G an
opening stand pipe K and an outflow cock L essentially as shown and described.
