An Improved Apparatus to be used for Fumigating Trees or Plants,
also for Destroying Vermin or Insect Pests, or for Disinfecting
Buildings and other such Places, or for Rendering Seeds Disease-
proof, together with a Material for use in the same.
We, SAMUEL LOWE, of Collins Street, Melbourne in the Colony of Victoria,
Merchant, and RICHARD PICKUP PARK, of Forest Hill, Nunawading in the
aforesaid Colony, Engineer, do hereby declare the nature of our invention to be as
follows:-
The object of our present invention is to provide an apparatus which can be
employed for the following purposes.
Firstly. For fumigating trees or plants in order to destroy insect pests.
Secondly. For rendering disease proof seeds used in cultivation.
Thirdly. For destroying animal life or vermin.
Fourthly. For disinfecting buildings such as hospitals, dwelling houses, stables
or drains and other such places.
The principle of our invention lies in directing a steam blast around and through
conically formed heating, evaporating and amalgamating chambers for the purpose
of effecting the proper amalgamation and ejection of either disinfecting or fumigating
liquids or vapors.
The following is a brief description of our apparatus. It consists of a short
tubular metallic body which is vertically arranged above a conically shaped com-
partment in which vapors or fumes are generated. There are two portions projected
one from each of the two sides of said body; one portion consists of a sleeve which
carries an adjustablo steam blast nozzle. The other portion is a jacket in which is
arranged a perforated cone distributor, as also an evaporator, each of which is
hereinafter described.
The aforesaid adjustable steam blast nozzle consists of a tube, the outer circum-
ference of which is screw threaded so that it may be screwed into a threaded
portion of the beforementioned sleeve which projects horizontally from the aforesaid
body.
The nozzle is formed at one end of said tube and there is a socket at the other,
to receive the end of a steam inlet pipe which is connected to an ordinary vertical
steam boiler.
An adjustable nut is arranged upon the screw threaded portion of said tubular
nozzle for the purpose of regulating the blast of steam issuing therefrom. The
jacket beforementioned consists of a double cone, one half portion of which lies
across the passage-way of the tubular body. It is termed the inner cone jacket,
and is divided into three flanged sleeves which are heated by the steam blast.
There is an annular space between each sleeve, thereby forming passage-ways for
the inlet of liquids or vapors to the amalgamating chamber hereinafter described.
The other half of the jacket is termed the outer cone jacket; it is projected from
one side of the tubular body, and is made with a bell shaped socket at its outer end
to receive the perforated cone distributor, as also one end of a short pipe to which
a length of hose is connected.
A sleeve nut is fitted upon said socket to retain the distributor and the short pipe
in a rigid position.
The aforesaid evaporator consists of a double cone arranged within the similarly
shaped jacket; one end of the former is projected into the nozzle end of the steam
blast.
An aperture is made in the upper side of said evaporator to allow fumes
any

page_text: generated therein to pass into an annular space left between the outer circumference
of the evaporator and the outer cone jacket, which space serves as an amalgamating
chamber.
A tank constructed with four compartments is arranged to supply different kinds
of disinfecting liquids through vertical tubes to the circumferential surface of the
inner cane jacket consisting of the three sleeves as beforementioned.
One of said tubes feeds a disinfecting liquid to the interior of the evaporator
but the flow of liquids from the tank to the apparatus is regulated by four plunger
valves, one arranged in eucli compartment. It should be here explained that the
axis of the tubular body is vertical and is at right angles to the horizontal axis of
the blast nozzle and the double cone evaporator and the correspondingly shaped
jacket.
The component parts of the disinfecting and fumigating agent which we use in
the vapor compartment, are as follow. Sulphur 80 pärts, tar 15 parts, prussiate of
potash 5 parts.
We do not confine ourselves to the mixing of these in the exact proportions as
we may vary them, or we may use other agents according to the purpose for which
the apparatus is used.
For the proper working of our apparatus a disinfecting liquid is first supplied to
the interior of the evaporator through the medium of its feed tube; other liquids
are also fed to the inner cone jacket namely the flanged sleeves; sulphur or another
inflammable agent is then ignited in the vapor compartment and the steam blast
may now be brought into operation. The steam as it issues from the nozzle acts
upon, and heats the evaporator to produce a vapor therein. This vapor is withdrawn
together with the liquids falling upon the heated inner cone jacket and also the
vapors generated in the compartment provided for that purpose; and directed into
the amalgamating chamber from whence the combined vapors or liquids are forced
through the perforated cone distributor and thence through the hose by means of
which the place to be disinfected or fumigated may be treated.

We, SAMPEL LOWE, of Collins Street, Melbourne, in the County of Bourke, 40
Merchant, and RICHARD PICKUP PARK, of Forest Hill, Nunawading, in the
aforesaid County Engineer, do hereby declare the nature of our invention
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 our present invention is to provide an apparatus which can be 46
employed for the following purposes.
Firstly, for fumigating trees or plants in order to destroy insect pests.
Secondly, for rendering disease proof seeds used in cultivation.
Thirdly, for destroying animal life or vermin.
Fourthly, for disinfecting buildings, such as hospitals, dwelling houses, stables or 50
draine and other such places.
The principle of our invention lies in directing a steam blast through the
apparatus for the purpose of heating, evaporating, and amalgamating and ejecting
either disinfecting or fumigating liquids or vapors.

page_text: But in order that our invention may be clearly understood we will now refer to
the accompanying sheet of drawings which are to be taken as part of this
Specification and read therewith.
*Figure 1, represents the arrangement of the various parts which are used in
connection with our apparatus.
Figure 2, represents a plan.
Figure 3, is a sectional elevation of apparatus.
Similar letters of reference indicate similar or corresponding parts where they
occur in the several views.
In the drawings, (a) represents the globular shaped body of apparatus with three
projecting branches (b), (c) and (d). One branch lettered () is divided into two
compartments by the partitions (e) and (f), whilst, the branch (d) is connected to
a pipe in communication with a sulphur chamber hereinafter described.
The third branch lettered (c) carries the coupling of a hose (4), and the truncated
hollow cone (i) which is arranged to form a well.
Within the apparatus there are three chambers lettered respectively (j), (k)
and (2). The first one serves as a steam inlet to apparatus and is for either heating
liquids or producing vapors. This steam inlet is provided with a nozzle (m) to
direct a blast of steam from said chamber through the aforesaid truncated cone (i).
The second one is for evaporating liquids, whilst, the third is for amalgamated
liquids or vapors.
(n) and (n¹) are two tubes, the former is arranged to feed a liquid to the
evaporating chamber (k), whilst the latter (n) is also employed to feed a different
kind of liquid to the amalgamating chamber (1).
(o) is an aperture made in the upper side of said evaporating chamber (*) to
allow any fumes generated therein to pass into the chamber (4) where they
amalgamate with the fumes coming from the sulphur chamber (p) arranged upon
the crown of the steam boiler (r).
(q) is a sliding door for said sulphur chamber.
The aforesaid steam chamber () is formed centrally through the apparatus and
is closed at one end as shewn at Figure 3.
(s) is a steam inlet pipe connected with said boiler (r) and chamber (j).
() is a stop inlet pipe connected) with said boilor (r) and chamber admitted
to the apparatus, or when the latter is shut off from the steam boiler the fumes
from the sulphur chamber may be allowed to escape. (v) is a cistern in which the
disinfecting or fumigating liquids are placed. Said cistern is provided with an air
inlet tube (w) funnel (a) and a draw off tap (y).
For the purpose of either fumigating trees or destroying vermin or insect pests
through the medium of our apparatus, we use a liquid or solution, the component
parts of which are as follow:-
10 gallons of cold water.
10 pounds of unslaked lime.
5 pounds of soft soap.
4 ounces of prussiate of potash.
2 ounces of creosote.
1 gallon of kerosene.
This solution is diluted before use in the apparatus, that is to say, to every one
part of solution 10 parts of water are added.
The method of using our apparatus is as follows.
Steam is generated in the boiler (r) and admitted through the chamber (5) which
thereby becomes heated. The aforesaid diluted solution is then placed in the
cistern () and allowed to drip therefrom into a compartment beneath, from the
latter it passes through the tube (n) into the chamber (k) to be converted into a
vapor.
This vapor escanes through the aperture (a) into the analgamating chamber (1)

page_text: nozzle (m) it draws the sulphur fumes through the pipe (g) into the chamber (7) to
be amalgamated with the vapor and also the steam passing through the cone (2)
and hose by means of which the fumigating agent is directed to the parts requiring
treatment.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner it is to be performed, we declare that what we
claim is:-
:-
Firstly. An apparatus consisting of the chambers (4) and (7) formed in conjunction
with the stean chamber () as also the compartment (6) with tubes (a) and (a),
substantially as and for the purpose hereinbefore described and as illustrated in our
drawings.
Secondly. An apparatus, such as herein described and as illustrated, having a
cone () formed therein to receive the nozzle (m) of the steam chamber (j)
substantially for the purpose specified.
Thirdly. The general combination and arrangement with the amalgamator of the
pipe (g) tube (1) sulphur chamber (p) cistern (r) with air pipe (w)"and funnel as
and for the purpose specified and as illustrated.
