Improvements in or Applicable to Fire-extinguishers or
66 Extincteurs."
We JOSEPH HALL and JAMES HALL both of Anglesey Street, Park Road, Oldham
in the County of Lancaster, Fire Engineers, do hereby declare the nature of our
invention for IMPROVEMENTS IN OR APPLICABLE TO FIRE EXTINGUISHERS, OR
"EXTINCTEURS," to be as follows:-
"
This invention relates to that class of fire-extinguishing apparatus known as
Extincteurs in which a glass bottle containing an acid is held or suspended
in a closed vessel containing an alkaline solution, the bottle being broken to form the
extinguishing fluid, and the object of our invention is to improve the means for
suspending the said bottle, and for breaking the same when it is desired to make use
of the "Extincteur."
Into the top or end of the vessel which contains the alkaline fluid I screw a short
tube provided with a cap screwed or otherwise attached thereto.
This cap is formed with a chamber open at the bottom, and extending into the tube,
the opening being sufficiently large to allow the neck of a bottle to pass, but not the
flange at the top of the said neck, a slotted opening being made at one side of
the said chamber to allow of the bottle neck being inserted therein sideways.
The bottle, being filled with acid, is inserted into the chamber in this cap which is
then fixed on or into the open end of the tube as above described, and the bottle
which hangs from the cap is made sufficiently long to project for a suitable distance
into the vessel containing the alkaline solution.
I form a short branch from the above named tube in which I mount a screwed
spindle passing through a stuffing-box at the outer end of the said branch and
provided with a suitable handle at its outer end. I prefer to mount a loose boss on
the inner end of this spindle provided with projections so that, when it is required to
extinguish a fire, the handle is turned the spindle enters the tube and the said
projections on the boss are forced against the glass bottle and break it.

page_text: The acid is thus immediately mixed with the alkali.
I prefer to form a four threaded screw upon the spindle to accelerate the breakage
of the bottle which can be accomplished by one turn (or less) of the handle.
It will be evident that this invention may be readily applied to existing
"Extincteurs."

COMPLETE SPECIFICATION.
Improvements in or Applicable to Fire Extinguishers or
Extincteurs.
We JOSEPH HALL and JAMES HALL both of Anglesey Street, Park Road, Oldham
in the county of Lancaster Fire Engineers do hereby declare the nature of our said
invention and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement :-
This invention relates to that class of fire extinguishing apparatus known as
"Extincteurs" containing an alkaline solution and in which a glass bottle containing
the necessary acid is suspended the bottle being broken to allow the acid to fall and
mix with the alkaline solution to form the extinguishing fluid and the object of our
invention is to improve the means of suspending the said bottle and for breaking the
same when it is desired to make use of the "Extincteur."
And in order that this our said invention may be the more readily understood and
carried into practical effect we have hereunto annexed a drawing illustrative of our
improved Extincteur and will now proceed to describe the same with the assistance of
the various Figures and letters of reference marked thereon.
Fig. 1 is a front exterior view of our improved Fire Extinguisher or Extincteur
and Fig. 2 is a similar front view but shewing the neck in section.
Fig. 3 is a separate front view on a large scale and Fig. 4 a plan view of the cap
we employ for suspending the glass bottle in position in accordance with our
invention.
In all the views a is the casing or body of the Fire Extinguisher (or Extincteur)
which is of the ordinary construction and material and which vessel contains the
usual alkaline fluid. Into the top of this vessel a we screw a short tube b provided
with a cap c screwed or otherwise attached thereto.

page_text: This cap c (see Figs. 3 and 4) is formed with a chamber d open at the bottom and
extending into the tube 6 as illustrated, the opening being sufficiently large to allow
the narrow neck of the glass bottle e to pass but not the flange at the top of the said
neck, a slotted opening f being made at one side of the said chamber d to allow
of the bottle neck being inserted therein sideways.
The bottle e containing the necessary acid is first inserted into the chamber d,
the cap c is then screwed or fixed on or into the open end of the neck or tube b as
above described, and the bottle e which hangs from the cap is made sufficiently long
to project for a suitable distance into the vessel a containing the alkaline solution.
We form a short branch from the above named tube b in which we mount a
screwed spindle g passing through a stuffing box h at the outer end of the said branch
and provided with a suitable handle i at its outer end.
We prefer to mount a loose boss g¹ on the inner end of this spindle g provided with
prongs or projections as illustrated so that when it is required to extinguish a fire,. the
only thing requisite to be done is to turn the handle i when the spindle g enters the
tube 6 and the projections on the boss g¹ are forced against the glass bottle e and so
break it.
The acid is thus free to escape and immediately becomes mixed with the alkali.
We prefer to form a four threaded screw upon the spindle g to accelerate the
breaking of the bottle e and which can thus be accomplished by one half turn (or less)
of the handle i.
It will be evident that this invention may be readily applied to existing
"extincteurs."
In conclusion we wish it to be distinctly understood that we do not claim broadly
holding an acid bottle by the neck in the screw cap of an extincteur or breaking an
acid bottle by means of a screw when held by the screw cap.
Having thus particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is:-
The improved combination and arrangement of apparatus for suspending
the glass acid bottle in position and for breaking the same substantially as and for
the purpose hereinbefore described and illustrated on the accompanying drawing.

Extincteurs.
We JOSEPH HALL and JAMES HALL both of Anglesey Street, Park Road, Oldham
in the county of Lancaster Fire Engineers do hereby declare the nature of our said
invention and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement :-
This invention relates to that class. of fire extinguishing apparatus known as
"Extincteurs" containing an alkaline solution and in which a glass bottle containing
the necessary acid is suspended the bottle being broken to allow the acid to fall and
mix with the alkaline solution to form the extinguishing fluid and the object of our
invention is to improve the means of suspending the said bottle and for breaking the
same when it is desired to make use of the "Extincteur."
And in order that this our said invention may be the more readily understood and
carried into practical effect we have hereunto annexed a drawing illustrative of our
'mproved Extincteur and will now proceed to describe the same with the assistance of
the various Figures and letters of reference marked thereon.
Fig. is a front exterior view of our improved Fire Extinguisher or Extincteur
and Fig. 2 is a similar front view but showing the neck in section.
Fig. 3 is a separate front view on a large scale and Fig. 4 a plan view of the cap
we employ for suspending the glass bottle in position in accordance with our
invention.
In all the views a is the casing or body of the Fire Extinguisher (or Extincteur)
which is of the ordinary construction and material and which vessel contains the
usual alkaline fluid. Into the top of this vessel a we screw a short tube b provided
with a cap c screwed or otherwise attached thereto.
This cap c (see Figs. 3 and 4) is formed with a chamber d open at the bottom and
extending into the tube b as illustrated, the opening being sufficiently large to allow
the narrow neck of the glass bottle e to pass but not the flange at the top of the said
neck, a slotted opening f being made at one side of the said chamber d to allow
of the bottle neck being inserted therein sideways.
The bottle e containing the necessary acid is first inserted into the chamber d,
the cap c is then screwed or fixed on or into the open end of the neck or tube b as
above described, and the bottle e which hangs from the cap is made sufficiently long
to project for a suitable distance into the vessel a containing the alkaline solution.
We form a short branch from the above named tube b in which we mount a
screwed spindle g passing through a stuffing box h at the outer end of the said branch
and provided with a suitable handle i at its outer end.
We prefer to mount a loose boss g¹ on the inner end of this spindle g provided with
prongs or projections as illustrated so that when it is required to extinguish a fire, the
only thing requisite to be done. is-to-turn_the_handle. when the spindle g enters the

page_text: tube b and the projections on the boss g₁ are forced against the glass bottle e and so
break it.
The acid is thus free to escape and immediately becomes mixed with the alkali.
We prefer to form a four threaded screw upon the spindle g to accelerate the
breaking of the bottle e and which can thus be accomplished by one half turn (or less)
of the handle i.
It will be evident that this invention may be readily applied to existing
"extincteurs."
Having thus particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is:
1st. The improvements in fire extinguishers or extincteurs substantially as herein-
before described.
2nd. The improved combination and arrangement of apparatus for suspending
the glass acid bottle in position and for breaking the same substantially as and for
the purpose hereinbefore described and illustrated on the accompanying drawing.
