PROVISIONAL SPECIFICATION.
Machine or Apparatus for Introducing Material Substances into the
Water whilst it is Passing Through a Fire Hose Pipe on its way
to a House or Place on Fire.
I JOHN WELSH of 16 North Tay Street Perth, in the County of Perth
Superintendent of Police and Chief of the City of Perth Fire Brigade do hereby
declare the nature of my invention to be as follows:-
I construct a machine or apparatus into which 1 place quantities of materials
calculated to assist along with water in the speedy extinguishing of fires, which
materials transmit from said machine or apparatus to the water whilst it is
passing through a fire hose pipe from a pump, fire engine, water main, tank or
reservoir to a house or place on fire and this I do by a connexion I make betwixt
said machine or apparatus and said fire hose pipe. The said machine or apparatus
consists of a metal cylinder having several divisions in it and revolves inside an
outer metal case and driven by hand or power. The materials I use are sand, salt,
sulphur, sulphate of ammonia, alum or other fire extinguishing materials.

COMPLETE SPECIFICATION.
Machine or Apparatus for Introducing Material Substances into the
Water whilst it is Passing Through a Fire Hose Fipe on its way
to a House or Place on Fire.
I, JOHN WELSH, of 16 North Tay Street Perth, in the County of Perth,
Superintendent of Police and Chief of the City of Perth Fire Brigade, 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 :-
My invention relates to a machine or apparatus for introducing substances into
the water whilst it is passing through a fire hose pipe whilst being used in
extinguishing a fire in a house or other building or place. My invention consists
of a cylinder of metal or other suitable material having two or more chambers
or divisions in it, but preferably four. The cylinder is closed at the ends, and in
each chamber or division there are two openings, one in the rim, and the other
at or near the centre. The opening at or near the centre has a covering of
india-rubber over it and fastened at one end, and when the machine or apparatus
is in use it acts as a valve. The cylinder revolves in a case of metal or other
suitable material by means of hand or other power. This case is partly lined
with india-rubber or other elastic material, and has an opening at the top and
side. There is also a pipe attached to the bottom of the case having a valve
which is opened and closed by hand, and at the end of said pipe there is a male
screw or bayonet joint coupling. I have also a sole or plank of wood into which
a pipe is fixed having a female screw or bayonet joint coupling at the one end
and a male screw or bayonet joint coupling at the other, with a female screw or
bayonet joint coupling in the centre of said pipe into which the male screw or
bayonet joint coupling on the end of the tube or pipe attached to the bottom of
the case is screwed or inserted.
In order that my invention may be properly understood and readily carried into
effect I have hereunto appended an explanatory sheet of drawings in the several

page_text: relerence.
Figure 1 is a front elevation.
Figure 2. is an end elevation...
Figure 3 is a section.
The cylinder has four divisions or sections B B, B; B Each of these divisions
has two openings, one C. in the rim, and the other Drat or near the centre, both
of which will be hereinafter more fully explained. The cylinder is enclosed in a
casing E, and it is operated by band or other power: by the handle F. This
casing is partly lined with india-rubber G, or other elastic material, and it is
provided with an opening H at the top, into which there is placed a hopper I
through which the material is passed into one of the sections of the cylinder.
There is also a plug J at the side of the casing E which shall be hereafter more
fully described. K is the pipe which is attached to the bottom of the casing E,
and this pipe is provided with a valve L which is operated by hand. Another
pipe M is fixed to a sole or plank of wood N, and this pipe M is connected to the
pipe K by means of a male screw or bayonet joint coupling.
On fire breaking out I take my machine or apparatus to the fire together with
such materials as I think will be most suitable to aid in extinguishing the fire.
On arriving at the fire I place the machine or apparatus betwixt the fire engine,
stand pipe or pump and the fire and I couple the hose pipe leading from the fire
engine, stand pipe or pump to the end of the pipe M fixed in the sole or plank of
wood N, and thus allow the water coming from the fire engine, stand pipe or pump
to be played at once upon the fire. then charge the cylinder with the materials
and open the valve L, thus allowing a portion of the water passing through the
hose pipe towards the fire to enter the nearest chamber or division of the cylinder
through the opening C, which it no sooner does than the material in the chamber
or division falls into the water passing through the hose pipe towards the fire and
is carried forward with the water and ejected with the water upon the fire, then
give the cylinder another quarter turn and discharge the contents in the next
section or division in the same manner as that just described, and so on charging
and discharging each division of the cylinder as it is revolved until the fire is
extinguished.
Any water which may be left in the division just discharged escapes through
the opening J, and any air or gas which may accumulate in the divisions escapes.
through the valve D..
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed declare that what I
claim is :-
. 1. The introduction of material substances into the water whilst it is passing
through a fire hose pipe attached to a fire engine, stand pipe or pump, on its way
to a house, ship, or place on fire for the purpose of extinguishing the fire.
2. The machine or apparatus for introducing material substances into the water
whilst it is passing through a fire hose on its way to a house or other. building or
place on fire, substantially as described and shown on the accompanying sheet of
drawings.
