PROVISIONAL SPECIFICATION.
Improved Means of, and Apparatus to be used for, Disinfecting.
and for Destroying Vermin, and like Purposes.
I, JAMES ORCHARDSON of Ford Cottage, Ford, in the County of Lancaster,
Book-keeper, do hereby declare the nature of my said Invention to be as follows:-
My Invention relates to the disinfecting of enclosed spaces such as ships' cabins,
berths, and holds, dwelling rooms, and the like and to the destruction of vermin
(insects), and like purposes.
According to my Invention I use a steam generator which may be heated by
charcoal and I prefer to combine and burn sulphur or like disinfectant or vermin
destroying material with the fuel; the resultant fumes of the fuel and sulphur (or
other material) are caused to pass to a mixing tube or chamber, where the steam
generated in the generator propels and mingles with the fumes from the fire. I also
combine and mix with the steam carbolic acid or other suitable disinfecting or vermin
destroying fluid or material.
The apparatus may be of a size and form so as to be capable of being carried by a
person, or not, according to the conditions and requirements of its application.
An apparatus according to the invention may, for example be of the following con-
struction a cylindrical vessel having a dome thereon and provided at the bottom
with a casing forming a fire place containing a tray suitable for burning charcoal or
other fuel, and with an ash tray; a pipe passing up from the fire place through the
vessel and out at the top where it terminates in a nozzle, or a screw coupling
for fixing a flexible pipe thereto; a steam pipe and a steam controlling cock or valve
disposed on the top of the vessel or steam generator and a cup or vessel for supplying
carbolic acid or other equivalent fluid or material (either in a powdered or liquid
state) connected with or on said steam pipe, which pipe and the gaseous fire pipe
from the fire place are connected as described.
.
In action, a charcoal fire is placed under the steam generator of the apparatus
which contains water, and sulphur or other suitable material is mixed with the fuel
and the fumes therefrom pass up the pipe or chimney. Steam is turned on through
the steam pipe, and a feed of carbolic acid or its equivalent is given, and the com-
bined steam carbolic acid, and fumes or gases from the fire pass out from the
directing nozzle or the flexible pipe nozzle, and can be directed onto the part or into
the place that it is required to disinfect.
The apparatus may be provided with a suitable handle or handles for holding it or
carrying it and with a steam safety valve and a water gauge.
In some cases where convenient the steam may be supplied from a separate steam
generator such as the donkey boiler of a ship.

COMPLETE SPECIFICATION.
Improved Means of, and Apparatus to be used for, Disinfecting
and for Destroying Vermin, and like Purposes.
I, JAMES ORCHARDSON, of Ford Cottage, Ford, in the County of Lancaster, Book-
keeper, do hereby declare the nature of my said Invention and in what manner
the same is to be performed, to be particularly described and ascertained in and by
the followingstatement:
My Invention relates to the disinfecting of enclosed spaces, such as ships' cabins,

page_text: herths, and holds, dwelling rooms, and the like, and to the destruction of vermin
(insects), and like purposes..
According to my Invention I use a steam generator, which may be heated by
charcoal or by an oil or spirit lamp, and I prefer to combine and burn sulphur or
like disinfectant or vermin destroying material with the fuel; the resultant fumes of
the fuel and sulphur (or other material) are caused to pass to a mixing tube or
chamber, where the steam generated in the generator propels and mingles with the
fumes from the fire. I also combine and mix with the steam, carbolic acid or other
suitable disinfecting or vermin destroying fluid or material.
The apparatus may be of a size and form so as to be capable of being carried by a
person, or not, according to the conditions and requirements of its application.
An apparatus according to the Invention may, for example, be of the following
construction: a cylindrical vessel having a dome thereon and provided at the bottom
with a casing, forming a fire place, containing a tray suitable for burning charcoal or
other fuel, (or an oil or spirit lamp), and with an ash tray; a pipe passing up from
the fire place through the vessel and out at the top, where it terminates in a nozzle,
or a screw coupling for fixing a flexible pipe thereon; a steam pipe and a steam
controlling cock or valve disposed on the top of the vessel or steam generator, and a
cup or vessel for supplying carbolic acid or other equivalent fluid or material (either
in a powdered or liquid state), connected with or on said steam pipe, which pipe and
the gaseous fume pipe from the fire place are connected as described.
In action, a charcoal fire, or a lamp, placed under the steam generator of the
apparatus, which contains water, and sulphur or other suitable material is mixed with
the fuel or placed on a tray heated by the lamp, and the fumes therefrom pass up the
pipe or chimney. Steam is turned on through the steam pipe, and a feed of carbolic
acid or its equivalent is given, and the combined steam, carbolic acid, and fumes or
gases from the fire and sulphur, pass out from the directing nozzle or the flexible pipe
nozzle, and can be directed onto the part or into the place that it is required to
disinfect.
The apparatus may be provided with a suitable handle or handles for holding it or
carrying it, and with a steam safety valve and a watergauge.
In some cases, where convenient, the steam may be supplied from a separate steam
generator, such as the donkey boiler of a ship.
In the above description, and also in my Provisional Specification, I have stated
that the heating medium is charcoal; but, in practice, I find that it is better and
more effective to heat the steam generator by means of an oil or spirit lamp, and for
that reason, in this Specification, I confine the description of my invention almost
entirely to apparatus heated by a lamp.
The accompanying drawings which make a part of this Specification, serve
to illustrate my Invention.
The drawings are marked with letters and figures of reference corresponding with
those used in the following explanation, and like letters and figures are used to denote
like or corresponding parts throughout the several figures.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is an elevation of an apparatus, with the improvements according to my
invention; heated by means of an oil lamp.
Figure 2 is an elevation of an apparatus according to my Invention adapted to be
supplied with steam from a separate steam generator.
The following comprise the chief letters of reference used in the drawings to
designate the chief parts of the apparatus, the same letters being employed throughout
the drawings to denote the same or corresponding parts.
a designates the steam generator, which is provided with a dome a¹, an internal
flue (shewn in dotted lines), a perforated casing c, (having legs c¹), a water-gauge d,
and a safety valve e, and provided with a steam cock f.
g represents an oil lamp, provided with screw clamps h, by which it is connected

page_text: to the legs c', and thereby to the casing c and generator a. The lamp gis of the
duplex type and is provided with burners i having two chimneys k, as shown in dotted
lines and preferably of metal, and at the top of and between the chimneys there is a
metal tray 1, also shown in dotted lines, for holding sulphur or other suitable
disinfecting material; the chimneys k and tray 1, when the lamp is in position, are
surrounded by the casing c, as shown in Figure 1.
m is an elbow pipe, fitted on the dome a¹ at the mouth of the flue to which it is
attached, by a screw coupling n, a flexible pipe p provided with a nozzles, having
a holding shield s of wood or other suitable non-conductor of heat.
t is a steam pipe, which is connected to the steam cock f and the elbow pipe m,
in which it ends in a nozzle t¹.
v is a cup or vessel with a stop cock w, provided on the steam pipe t, and employed
for holding and supplying carbolic acid or other equivalent fluid or material to the
steam pipe t.
The action of the apparatus is:-the steam generator a is supplied with water
through the feed screw a and the lamp g is lighted, and, when steam has been
raised, a portion of say sulphur is placed in the tray and say carbolic acid in the
vessel v;
the cock is then opened and also the cock of the vessel v, so that the
contents of the vessel will drip into the pipe t, mingle with and issue with the steam
through the nozzle t, where the jet draws in and forces through the pipe the fumes
from the sulphur, said steam, carbolic acid, and sulphur fumes, finally issuing from
the nozzles of the flexible pipe p, from whence it is directed to the place where
the disinfecting jet is to be employed or applied.
With reference to the arrangement shewn at Figure 2, the carbolic acid cup v
is placed on the nozzles of the flexible pipe p, and instead of the steam supply
being taken from the steam generator a it can be taken from any convenient source,
such as the steam generator of a ship, or a donkey boiler or the like. In so using
this part of the apparatus the carbolic acid is caused to drip from the cup into the
steam passing through the nozzle s, and passes out through the nozzle with the steam ;
the sulphur is in this case dispensed with.
The herein described apparatus is particularly applicable as a fumigator for
disinfecting Passenger and cattle ships, Public buildings, Schools, Hotels, Hospitals,
and the like, and for the destruction of vermin insects, and for like purposes.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:-
1. The means substantially herein described of disinfecting, and destroying vermin,
and like purposes,
which means consist in applying to the space or spot to be treated,
or operated upon, a disinfectant or disinfectants, such as described, by and mixed
with a jet of steam.
2. In a steam fumigator, the combination of a vessel for generating steam, a means
for heating such vessel, and means for containing and supplying sulphur or like
fumes, and a means for containing and supplying carbolic acid or like disinfectant ;
operating substantially as described.
3. In an apparatus of the kind herein described, the means of supplying steam
under pressure, and means of supplying carbolic acid or other disinfectant to such
steam; operating substantially as described.
4. The apparatus constructed and adapted to operate substantially as set forth with
reference to Figure 1 of the drawings.
5. The apparatus constructed and adapted to operate substantially as set forth with
reference to Figure 2 of the drawings.
