I, ROBERT WATKINSON of Gore Street, New Bailey Street, Salford, in the County
of Lancaster, Brass Founder, do hereby declare the nature of my invention for
IMPROVEMENTS IN FIRE EXTINGUISHERS OR EXTINCTEURS, 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 Extinguishers or Extincteurs
which comprises of a more simple method of arranging the mechanical parts, and
ensures greater facilities to break the bottle containing the acid or other liquid.
In making my improvements I use the ordinary cylindrical shaped tank A, shewn
in sectional elevation Fig. 1, for the purpose of holding the alkaline water required,
at any distance I may consider practicable from the top of said tank or cylinder I
secure to the side and inner part the boss B, and directly opposite the boss B₁ which
is carried through the side the outer portion being provided for and used as a stuffing
box C.
The before mentioned bosses are constructed to carry the shaft or axle D, which has
the bottle or acid holder E, connected thereto and arranged to slide on the shaft or
axle D, and secured by the set screw F, or if necessary can be made in one piece, the
bottle or acid holder E, is shewn in an upright position with the acid or other liquid
bottle G therein, by simply turning the handle H, at the end of the shaft or axle
(either way) the bottle G strikes against the breaking bars or brackets I, thus breaking
the bottle, the acid or other liquid mixing with the alkaline water immediately
generates carbonic acid gas which being absorbed by the water creates great pressure
in the tank or cylinder and is ejected through the discharge pipe J, at the top, but in
large sized Extinguishers the discharge will take place at the bottom.
The cylinder is recharged through the opening at the top which can be immediately
closed by the instantaneous action of the Cap or lid K.
In making my improvements I use brass or other suitable metal.
Fig. 2, is an end view shewing the position of the breaking bars or brackets I,
which are secured to the side of tank or cylinder A. I may without deviating from
the principals of my invention alter the shape or pattern of said bars or brackets I,

page_text: or use any suitable contrivance of a like nature to produce the same effect as before
mentioned.
Fig. 3, is another plan dispensing with the bottle G, and using it as a acid holder
only which is made of Lead or other suitable metal to resist the acid.
Fig. 4, is merely another view of the handle H.
I can adopt my improvements if necessary to a vertical, horizontal or any other
position.
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
1st. The motion of the bottle G obtained from the shaft or axle D, striking the
bars or brackets I, substantially as herein described.
2nd. The shaft or axle D, with the bottle or acid holder E, connected thereto, sub-
stantially as herein described.
3rd. The breaking bars or brackets I, substantially as herein described.
4th. The combination of the several parts or any mere modification of the same
substantially as herein described and illustrated.
