I, JAMES HASLAM of Bury Road Tonge near Bolton in the County of Lancaster
Chemical Fire Engine Manufacturer and Tin Plate Worker, do hereby declare the
nature of my said invention to be as follows :―
My invention relates to improvements in chemical fire-extinguishers in which a
vessel containing water or water in solution with a carbonate or alkaline compound
and a bottle containing acid are employed, and consists in providing means for
effectually and readily charging and breaking the said bottle so as to mix the acid
with the water.
The top end of the extinguisher case is provided with a metallic nozzle fitted with
a swivelling lid or cover. The joint is made by means of an Indian Rubber ring or
its equivalent, which is fitted into a recess or cavity in the nozzle and an annular
projection on the lid or cover. The nozzle and the lid or cover are secured together
by fastenings formed partly by segmental ribs on the outside of nozzle and segmental
recesses in the lid or cover.
The underside of the nozzle is fitted with a perforated vertical cage or casing for
the purpose of holding or carrying the acid bottle; the latter being carried on a
support or ledge at the bottom end thereof, or otherwise.
The bottles are "
wired" to protect thein and secure the stoppers, and assists in
clearing the vertical cage or casing of broken glass when drawn out. To the bottom
end of the wire cage is secured a metallic or other washer on which the bottle sits.
On the side of the extinguisher case is mounted a bar or plunger passing through a
stuffing box, and is provided with a knob or hand lever by which it may be pressed
inwardly against the glass bottle when the latter is required to be broken.

page_text: The outlet can be by means of a tap placed at the lower extremity of the extinguisher
case, or at the top end near the inlet nozzle, in the latter case a pipe descends to the
bottom, or nearly so, of the extinguisher; the bottom end being fitted with a rose or
its equivalent.
In another method I employ an eccentric mounted on a shaft or spindle for breaking
the acid bottle, the spindle passing through a stuffing box in the extinguisher case,
and is operated by a handle.
On the underside of the extinguisher case a cavity or chamber is provided to receive
spare acid bottles and packages containing charges.

Improvements in Chemical Fire-extinguishers.
I, JAMES HASLAM of Bury Road, Tonge near Bolton in the County of Lancaster,
Chemical Fire Engine Manufacturer and Tin Plate Worker, do hereby declare the
nature of my said 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 improvements in chemical fire extinguishers in which a
vessel containing water or water in solution with a carbonate or alkaline compound
and a bottle containing acid are employed, and consists in providing means for
effectually and readily charging and breaking the said bottle so as to mix the acid
with the water.
The top end of the extinguisher case is provided with a metallic nozzle fitted with
a swivelling lid or cover. The joint is made by means of an Indian Rubber ring or
its equivalent, which is fitted into a recess or cavity in the nozzle and an annular
projection on the lid or cover. The nozzle and the lid or cover are secured together
by fastenings formed partly by segmental ribs on the outside of nozzle and segmental
recesses in the lid or cover.
The underside of the nozzle is fitted with a perforated vertical cage or casing for
the purpose of holding or carrying the acid bottle; the latter being carried on a
support or ledge at the bottom end thereof or otherwise.
The bottles are "wired" to protect them and secure the stoppers and assist in
clearing the vertical cage or casing of broken glass when drawn out.
To the bottom
end of the wire cage is secured a metallic or other washer on which the bottle sits.
On the side of the extinguisher case is mounted a bar or plunger passing through a
stuffing box, and is provided with a knob or hand lever by which it may be pressed
inwardly against the glass bottle when the latter is required to be broken.
The outlet can be by means of a tap placed at the lower extremity of the extinguisher
case, or at the top end near the inlet nozzle, in the latter case a pipe descends to the
bottom, or nearly so, of the extinguisher; the bottom end being fitted with a rose or
its equivalent.
In another method I employ an eccentric mounted on a shaft or spindle for
breaking the acid bottle; the spindle passing through a stuffing box in the
extinguisher case, and is operated by a handle.
Fig. 1 is a sectional elevation of one modification of my invention. Fig. 2 is an
elevation of metallic nozzle for filling or charging the extinguisher. Fig. 3 is a plan
of same showing segmental ribs. Fig. 4 is a plan looking on underside of swivelling
lid or cover showing segmental ribs. Fig. 5 is a part sectional elevation of another
modification of my invention, and Fig. 6 is a sectional plan of same through
lino S¹ T¹.
A is the case of the extinguisher on the dome or top end of which is secured the
nozzle B provided with the elongated_end_C, to operate against the india-rubber
ring D in the swivelling lid or cover E. The outside of the nozzle B is provided

page_text: with the segmental ribs G, as shown more clearly in Figs. 2 and 3. The swivelling
lid or cover E is fitted with the circular ring H provided with a recess or cavity to
receive the india-rubber ring D. The circular ring H is secured to the lid or cover E
by the screwed stem I and nut K. The lower end of the lid or cover E is provided
with the segmental ribs L, as shown in Fig. 4, by which the same is securely fastened
when swivelled under the ribs G on the nozzle B. The segmental ribs G are
tapered as shown in Fig. 2 so that when the ribs L on the lid or cover E are swivelled
under the same an increased pressure is imparted to the joint ring D and the joint
securely made. The india-rubber ring D is provided with the projecting end D
which descends and fits into the upper end C of the nozzle B, by which the pressure
of gas in the extinguisher assists to make a tight joint. Immediately pressure is
imparted to the joint ring D it becomes stationary along with the ring H; the latter
allowing the lid or cover E to swivel round its outer surface.
The acid bottle M is carried in the cage or casing N provided with the perforations O.
The cage or casing N is secured to the casing A of the extinguisher by the metallic
crosspiece P.
The stuffing box R is secured to the side of the case A in which is mounted the
screwed plunger S, which is operated by the hand lever T from the outside, by which
the point of the plunger S is pressed inwardly against the glass bottle to break
the same.
The outlet from the extinguisher is by means of the tap U connected to the rose W
by the pipe V, or in the usual manner as shown in Fig. 5.
In lieu of the screwed plunger S I employ the eccentric ✗ mounted on the
spindle Y for breaking the acid bottle M, as shown in Fig. 5. The spindle Y passes
through the stuffing box R secured to the case A, and is operated from the outside by
the handle T. The inner end of the spindle Y is supported in the bearing Z secured
to the crosspiece P.
Having now particularly described and ascertained the nature of my said Invention
and in what manner the same is to be performed I declare that what I claim is :-
1. In a chemical fire extinguisher the use and construction of apparatus consisting
of the combination of the nozzle B with the segmental ribs G, india-rubber ring D,
ring H, stem I, nut K, and the swivelling lid or cover E with the segmental ribs L,
applied and operating substantially as and for the purpose herein set forth and as
shown on the drawings.
2. In a chemical fire extinguisher the construction and use of the screwed plunger S
for breaking the acid bottle M, applied and operating substantially as described and
shown on the drawings.
3. In a chemical fire extinguisher the use and construction of the eccentric X
mounted on the spindle Y for breaking the acid bottle M, applied and operating
substantially as described and shown on the drawings.
