We, JOHN HENRY GALLOWAY and JAMES WILLIAM GALLOWAY of 100 Bark
Street, Bolton in the County of Lancaster, Fire Engineers, do hereby declare the
nature of our said invention to be as follows :-
Our invention relates to improvements in what are known as chemical fire
extinguishers and consists in providing ready and efficient means for charging and
ro-charging the same.
This we accomplish by mounting on the case forming the extinguisher a metallic
nozzle provided with a frame for carrying the vessel or bottle containing acid or other
chemical substance to be mixed with the water when the use of the apparatus is
requisite. In the nozzle is disposed a cavity to admit an india-rubber ring to form an
air tight joint when covered by a hinged cap or cover. To facilitate the filling of the
extinguisher the upper end of the nozzle is provided with a bell-mouthed end or tun-
dish to which is hinged a metallic cap or cover, the latter being constructed with a
bevelled or other projection on its underside to operate on the india-rubber joint ring
in the nozzle or cavity. The cap or cover is secured in position-when closed---by a
bevelled end spring bolt mounted in a lug or boss-either radially or tangentially-
on the said bell-mouthed end or tun-dish, or otherwise. When mounted tangentially
the cap or cover is provided with a handle which operates with the bevelled spring
bolt, by which it is locked or secured. When the hinged cap or cover is being closed
it is pressed against the bevelled spring bolt, forcing it outwardly until the cap or
cover passes its projecting or bevelled end, when the spring forces the latter over the
outside of the cap or cover, or its handle, by which it is locked fast. The spring bolt
works through a lug or boss and its external end is provided with a knob by means
of which it can be withdrawn when it is desired to open the extinguisher to charge,
empty, or re-charge.

page_text: If desired the cap or cover can be secured-when closed-by a spring catch and
lever, or their equivalents, mounted on the said tun-dish, or other convenient position;
the position of the lid or cover being maintained by suitable guides. In lieu of the
spring catch and lever the handle may be hinged to the lid or cover and swivelled
sideways under a suitable projection to lock or secure the same.
In another modification the cap or cover is attached to a screwed spindle mounted
in a swivelling yoke or crossbar which allows of the whole being canted from the
inlet of the nozzle when requisite.
The bottle containing acid or other chomical substance is constructed specially to
sit in the frame under the nozzle, and is provided with a reduced projection extending
below its seat, which part is operated upon and broken by a hammer or mallet
mounted and operated in any convenient manner.

Improvements in Chemical Fire Extinguishers.
We, JOHN HENRY GALLOWAY and JAMES WILLIAM GALLOWAY of 100 Bark
Street. Bolton 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 :-
Our invention relates to improvements in what are known as chemical fire extin-
guishers and consists in providing ready and efficient means for charging and
re-charging the same.
a metallic
This we accomplish by mounting on the case forming the extinguisher
nozzle provided with a frame for carrying the vessel or bottle containing acid or other
chemical substance to be mixed with the water when the use of the apparatus is
requisite. In the nozzle is disposed a cavity to admit an india-rubber ring to form an
air tight joint when covered by a hinged cap or cover. To facilitate the filling of the
extinguisher the upper end of the nozzle is provided with a bell-mouthed end or tun-
dish to which is hinged a metallic cap or cover, the latter being constructed with a
bevelled or other projection on its underside to operate on the india-rubber joint ring
in the nozzle or cavity: The cap or cover is secured in position-when closed-by a
.bevelled end spring bolt mounted in a lug or boss-either radially or tangentially
on the said bell-mouthed end or tun-dish, or otherwise. When mounted tangentially
the cap or cover is provided with a handle which operates with the bevelled spring

page_text: bolt, by which it is locked or secured. When the hinged cap or cover is being closed
it is pressed against the bevelled spring bolt, forcing it outwardly until the cap or
cover passes its projecting or bevelled end, when the spring forces the latter over tho
outside of the cap or cover, or its handle, by which it is locked fast. The spring bolt
works through a lug or boss and its external end is provided with a knob by means of
which it can be withdrawn when it is desired to open the extinguisher to charge,
empty, or re-charge.
If desired the cap or cover can be secured-when closed-by a spring catch and
lever, or their equivalents, mounted on the said tun-dish, or other convenient position ;
the position of the lid or cover being maintained by suitable guides. In lieu of the
spring catch and lever the handle may be hinged to the lid or cover and swivellød
sideways under a suitable projection to lock or secure the same.
In another modification the cap or cover is attached to a screwed spindle mounted
in a swivelling yoke or crossbar which allows of the whole being canted from the
inlet of the nozzle when requisite.
The bottle containing acid or other chemical substance is constructed specially to
sit in the frame under the nozzle, and is provided with a reduced projection extending
below its seat, which part is operated upon and broken by a hammer or mallet mounted
and operated in any convenient manner.
Fig. 1 is a sectional elevation of a chemical fire extinguisher with our improve-
ments applied Fig. 2 is an elevation of same and Fig. 3 is a plan of tun-dish
and cap.
The case A of the extinguisher is made of suitable metallic materials; the top side
being in the form of a domo as shown, or in any other convenient form as desired.
On the dome B is placed the metallic nozzle C provided with the frame D to carry or
support the bottle E containing the acid or other chemical substance to be mixed with
the water in the case A when the apparatus is required to be used. The nozzle C is
provided internally with a cavity to admit the ring F of india-rubber or other suitable
substance, which forms an air-tight joint when the hinged cap or cover G is closed as
in Fig. 1. The upper end or side of the nozzle C is fitted with the tun-dish H to
facilitate the filling of the extinguisher with water. To the tun-dish H is hinged the
cap or cover G by the pin or centre I. The underside of the cap or cover G is
bevelled to operate on the joint ring F of india-rubber or other suitable substance.
When the cap or cover G is closed it is secured in position by the bevelled end spring
bolt J, which is mounted radially in the boss K on the tun-dish H. When the hinged
cap or cover G is being closed it is pressed against the bevelled spring bolt J until
the latter is forced back sufficiently to allow the cap or cover G to pass, after which
the spring L shoots the bolt J back over the outside of the same, by which it is
secured as in Fig. 1. The spring bolt J works through the boss K, and its outer end
is provided with the knob M, by which it can be withdrawn when it is desired to open
the extinguisher.
The bottle E sits on the seat N of the frame D and is provided with the reduced
projection or end O extending below its seat, which part is operated upon and broken
by the hammer or mallet P mounted on the centre Q. The hammer or mallet P is
operated by the sliding rod R mounted in the bearing S and stuffing box T secured to
the case A of the extinguisher. The sliding rod R extends to the outside of the
extinguisher and is connected to the operating handle U; the latter being pivoted to
the case A by the pins V and V₁ and stud W. When it is requisite to put the
extinguisher into operation it is effected by simply pulling the handle outwardly
which causes the hammer or mallet P to fall inwardly and smash the end O of the
bottle E.
Fig. 3 A. is a plan of the cap or cover G and tun-dish H with the spring bolt J
mounted tangentially on the tun-dish H. In this case the cap or cover G is provided
with the handle X on which operates the spring bolt J to secure the same.
Figs. 4 and 5 are a modification of our invention wherein the cap or cover G is
fitted with the hinged or pivoted lover a, which allows of the latter being swivelled
sideway under the projection b on the tun-dish H when the cap or cover G is closed.

page_text: The lover a is secured in position by the spring bolt J, which is similar to that described
in Fig. 1. If desired the lever a can be substituted with the handle c as in Figs. 6
and 7, being securod in position when the cap or cover G is closed by the spring
bolt J placed tangentially on the tun-dish H. The position of the cap or cover G in
this case is maintained by the guides d and k between which the handle e drops when
closing the same.
Figs. 8 and 9 are a modification wherein the cap or cover G is attached to the
screwed spindle mounted in the swivelling yoke or crossbar 1, which allows of the
whole being canted when the cap or cover G is raised sufficiently by the screw h and
hand wheel m. The yoke or crossbar is mounted on the pins or centres p on the
side of the nozzle C.
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. In a fire extinguisher the use of the externally hinged cap or cover G in com-
bination with the joint ring F and spring bolt J, applied and operating substantially
as described and as shown on the drawings.
2. The respective combinations and arrangements of the externally hinged cap or
cover G, nozzle C, spring bolt J, tun-dish H, frame D, and the handle or lover for
oporating the same, substantially as described and shown on the drawings.
3. The combination and arrangement of the cap or cover G, swivelling yoke 1, and
screwed spindle h, applied and operating substantially as described and shown on the
drawings in Figs. 8 and 9.
4. The use of the bottle E with the projecting end O for the purpose herein set
forth, substantially as described and shown."
5. In a fire extinguishor the construction and use of the hammer or mallet P,
sliding rod R, and fulcrum Q, with the various connections for supporting and
operating the same, substantially as described and as shown on the drawings in
Figs. 1 and 2.
