PROVISIONAL SPECIFICATION.
Improvements in Fire Extincteurs.
I, JOHN WILLIAM ENEAS GUNN GIBBS of 15 Carnarvon Street in the City of
Glasgow Commercial Agent do hereby declare the nature of this invention to be
as follows:-
This invention relates to fire extinguishing apparatus of the class known as
extincteurs and it consists of improved devices for supporting or securing and for
breaking the bottle containing the acid employed in such apparatus for generating
carbonic acid gas by admixture with water containing an alkaline carbonate within
the extincteur.
The upper end or neck of the extincteur is of cylindrical form and is made with a
shoulder serving to support a loose framing within which the bottle is carried. This
framing is composed of a ring surrounding the bottle at about its mid length
or near its lower end and connected to a disc or flange piece fitted over the bottle
neck the said disc being fitted with a jointed clasp or ring embracing the neck and
supporting the weight of the bottle. The bottle supporting frame is placed in the
cylindrical neck or casing of the extincteur the flange or disc resting on the
supporting shoulder and a lid or cover pivoted on the neck piece and provided with
a washer is screwed down tightly by means of a screw pin hinged or jointed to the
neck of the cover and having on it collars by which it is held loosely to the
cover.
In the side of the neck piece of the extincteur is fitted a sliding piston passing
through a stuffing box and provided with an external knob. This piston serves as
a hammer for breaking the acid bottle when the extincteur is to be used and it is
protected when out of use by a cylindrical cover fitted over the stuffing box.

COMPLETE SPECIFICATION.
Improvements in Fire Extincteurs.
I, JOHN WILLIAM ENEAS GUNN GIBBS of 15 Carnarvon Street in the City of
Glasgow, Commercial Agent do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement :—
This invention relates to fire extinguishing apparatus of the class known as
extincteurs and it consists of improved devices for supporting or securing and for
breaking the bottle containing the acid employed in such apparatus for generating
carbonic acid gas by admixture with water containing an alkaline carbonate within
the extincteur.
As represented in the accompanying drawings in sectional elevation at Figure 1
and in side elevation at Figure 2 the upper end or neck A¹ of the extincteur A is
of cylindrical form and is made with a shoulder a serving to support a loose
framing B B within which the bottle C is carried. This framing is composed of
a ring B surrounding the bottle C at about its mid length or near its lower end
and connected to a disc or flange piece B₁ fitted over the bottle neck the said disc
being fitted with a jointed clasp or ring 6 embracing the neck and supporting the
weight of the bottle or the bottle may be formed with a shoulder from which it
may be hung. The bottle supporting frame B B is placed in the cylindrical
CD 071

page_text: neck or casing A¹ of the extincteur the flange or disc B' resting on the supporting
shoulder a and a lid or cover D pivoted at d on the neck piece A' and provided
with a washer d' is screwed down tightly by means of a screw pin E hinged or
jointed at e to the neck A¹ and having on it a collar or wing nut F entering a jaw
piece F in the cover D.
In the side of the neck piece A' of the extincteur is fitted a sliding piston G
passing through a stuffing box H and provided with an external knob G. This
piston serves as a hammer for breaking the acid bottle when the extincteur is to
be used and it is protected when out of use by a cylindrical cover I fitted over the
stuffing box.
The tube J to which the hose pipe K is attached is secured on the outside of
the extincteur to prevent corrosion of the metal by the acid introduced when in
use not being thoroughly cleaned out and over the end of this tube within the
extincteur a grating of wire gauze or like material is fitted. The cock j is placed
in the nozzle L of the hose instead of as is usual, at the junction of the tube J and
the extincteur and if desired a cock may also be provided at the upper end of this
tube for shutting off liquid from the hose pipe.
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 combination of parts constituting the improved fire extincteur herein-
before described with reference to the annexed drawings.
2. In fire extincteurs a device for supporting or securing the acid bottle
constructed substantially as described.
3. In fire extincteurs a device for use in breaking the acid bottle constructed
and fitted substantially as described.
