Year: 1885

page_text: We JOHN KISSACK JOSHUA FOSTER of 8 Bury New Road, Bolton, Chemical
Fire Engine Manufacturer, and JAMES HASLAM of Bury Road, Tonge near Bolton,
Tin plate Worker, both in the County of Lancaster, do hereby declare the nature
of our invention for "IMPROVEMENTS IN CHEMICAL FIRE EXTINGUISHERS," to be
as follows:-
=
This invention relates to improvements in fire extinguishing apparatus know by
the name of "L'Extincteur," in which a vessel containing water or water in
solution with a carbonate or alkaline compound and one or more vessels or bottles
containing acid, or if desired a corresponding number of bottles containing alkaline
solution or alkaline in lump or powder are employed, together with means for
effectively and readily breaking the said bottles so as to mix the acid with the
water, and alkaline in solution with water when the apparatus is required to be
used, causing uninflammable gas and liquid to be projected on the fire, with
facilities for charging and recharging the same when requisite.
The case of the "L'Extincteur" is made in a conical or other form of suitable
metallic materials. The bottles containing acid or other solutions or powder are
held and supported in suitable hollow casings provided with openings on the top
side to allow of the action of the hammers for breaking the same; the bottom side.
being provided with slits or perforations to admit of the contents of the bottles
falling into the contents of the case of the "L'Extincteur," at the same time
preventing broken glass falling into the same and choking the outlet which
obviates a defect long desired. The bottles are "wired" which protects them and
secures the stoppers and assists in clearing the casings of broken glass when drawn
out after they are broken. The casings are closed after the admittance of bottles
by suitable screw caps or other equivalents.
The hammers for breaking the bottles are mounted loosely on shafts or centres
fixed in any convenient manner across the casing of the "L'Extincteur" in suitable
bearings. To the hammer centres are disposed suitable levers to which are
connected links and rods, the latter passing through stuffing boxes to the outside,
and are provided with loose or revolving handles to prevent strain or breakage.to
the sliding rods and connections. The operation of breaking the bottles is effected
by pulling each handle out in a horizontal direction which causes the lever to

raised by simply reversing the operation.
To enable the "L'Extincteur" to be more expeditiously recharged we place the
apparatus on a hollow pedestal of sufficient capacity and suitably lined to hold one
or more charges of water or alkali in solution with water.
In another arrangement the conical or other casing of the "L'Extincteur is
composed or formed double, leaving a cavity or chamber for the purpose of holding
one or more charges of water or alkali in solution with water, in which case
suitable arrangements are provided for charging and emptying the same.

We, JOHN KISSACK JOSHUA FOSTER of 8 Bury New Road, Bolton, Chemical
Fire Engine Manufacturer, and JAMES HASLAM of Bury Road, Tonge near Bolton,
both in the County of Lancaster, Tin plate Worker, do hereby declare the nature
of our said 'Invention for IMPROVEMENTS IN CHEMICAL FIRE EXTINGUISHERS,"
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 improvements in fire extinguishing apparatus know
by the name of L'Extincteur," in which a vessel containing water or water in
solution with a carbonate or alkaline compound and one or more vessels or bottles
containing acid, or if desired, a corresponding number of bottles containing alkaline
solution or alkaline in lump or powder are employed, together with means for
effectively and readily breaking the said bottles so as to mix the acid with the
water, and alkaline in solution with water when the apparatus is required to be
used, causing uninflammable gas and liquid to be projected on the fire, with
facilities for charging and re-charging the same when requisite.
Fig. 1 of the accompanying drawings is a sectional elevation of so much of a
chemical fire extincteur" as is necessary to illustrate our present invention with
two bottles containing acid or other solutions or powder-Fig. 2 is a plan of Fig. 1
through line A B, partly in section, shewing the connections between the hammers
and triggers-Fig. 3 is an elevation of our improved "extincteur," partly in section,
wherein only one bottle containing acid, or other solution or powder is employed-
Fig. 4 is a front elevation of pedestal for supporting the "extincteur" as well as
that of holding water or other liquids for re-charging the same, and Fig. 5 is a
sectional elevation of same.

page_text: The case C of the "extincteur" is made conical as shewn for the purpose of
throwing almost all the weight to the bottom, and consequently over the "loins"
or "hips" of the operator when carrying it for action or otherwise, which has a
tendency to keep the operator in an upright position. The conical case C of the
"extincteur" is made of hardened planished copper or other suitable metallic
materials. The bottles D containing acid or other solutions or powder are held
and supported in the horizontal casings E provided with the openings G on the
top side to allow the hammers H to operate on the bottles D when required to be
broken. The bottom side of the casings E are provided with the slits or per-
forations I to allow of the contents of the bottles D-when the latter are broken-
mixing with the water or chemicalised solution in the "extincteur," at the same
time through the smallness of the said slits or perforations-preventing broken
glass falling into the same, thereby obviating the choking of the outlet J. The
hollow casings E are extended to the outside of the conical case and closed by the
screw caps or covers K.
The hammers H are attached to the hollow shafts M, the latter being mounted on
the centres O placed across the conical casing C of the "extincteur" and held in
the bearings P, being passed through and soldered up on the outside. To the
hollow shafts M are fixed the levers R connected by the links S to the trigger
rods T, the latter passing through the stuffing boxes U to the outside; the trigger
rods T are provided with the loose or revolving handles or knobs W. The handles
or knobs W are fitted with the wire loops 4 to which are attached leather straps
or other equivalents-not shewn on the drawing_secured to the case of the
"extincteur" to prevent the hammers H falling and breaking the acid bottles D
when not required.
To protect the bottles D and secure the stoppers in same they are bound with
the wire bands 3, by which-when the bottles are broken-the broken glass is
withdrawn instantly when the case is ready for another charge or bottle.
This apparatus is operated as follows:-
Screw down the valve 4 at the top by the screw and handle 5 and open the
inlet to the "extincteur," through which water, or other liquid, and chemicals are
charged, after which the same is closed by the valve 4 on reversing the action of
the screw and handle 5. In case of fire cut one of the straps-not shewn-secured
to the handles or knobs W of the trigger rods T and pull the same in an outwardly
direction, which causes the hammer H attached to it to fall and break one of the
bottles D, when the "extincteur" is ready for operation, which on opening the
tap 6 by the handle 7 allows the chemicalised water to flow through the rose and
outlet J to the opening 9, to which is attached the usual flexible pipe and nozzle.
After the charge is spent the valve is opened and the "extincteur" re-charged
with water or liquid and chemicals, then closed as before stated, when the
remaining acid bottle can be broken and the "extincteur" is ready for operation as
before.
Referring now to Figs. 4 and 5:
The hollow casing or pedestal L is constructed of suitable materials and mounted
in the base 11, being provided for a double purpose, that is, serving as a reservoir
or reserve for water or other suitable liquid, as well as being a stand or support
for the "extincteur" when not in use. The pedestal L is made conveniently high
to facilitate mounting the "extincteur" on the "back" of the operator, and is
provided with the brackets 12 for supporting the ladles 13 for emptying the water
or other liquid from the hollow casing or pedestal L into the "extincteur."
Having now 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 :-
1. The method, substantially as herein described, of mounting bottles, containing
acid or other solutions or powder, in a horizontal position in a chamber or chambers

page_text: inserted in an "extincteur," having orifices on the outside of the "extincteur" to
admit same.
2. In apparatus applied in the manner referred to in the preceding claim, in
combination with a fire "extincteur" the chamber or chambers E for holding the
bottles D, with the openings G, the slots or perforations I, and the screw caps or
covers K, substantially as herein described.
3. Constructing the case C of the "extincteur" in a conical form, substantially
as herein described and illustrated by the drawings for the purpose specified.
4. The use and employment of the hammers H and their connections with the
triggers, applied and operating, substantially as herein described and illustrated on
the drawings.
5. The respective combinations of our improved fire "extincteur," operating
substantially in the manner described and as shewn respectively in the drawings
in Figs. 1, 2, and 3.
6. The use, construction, and employment of the pedestal L for the purpose
specified, and as shown in Figs. 4 and 5.
