I, FRANCIS GOODALL WRIGHT, of 66, Kennington Road, in the county of Surrey
Blacksmith, do hereby declare the nature of this invention to be as follows:-
This invention relates to means for giving an alarm in case of fire the said means
comprising, if required, apparatus for use in extinguishing fires.
In carrying out my invention I make use of an explosive in a suitable form and I
find it advantageous to provide a case or holder formed in two parts one part adapted
to be fixed in any convenient position in a room or like place, the other part being
moveable.
The said case or holder is constructed to receive the explosive charge I employ,
with which a fuse is connected, extending to any suitable part or parts of the room or
the like.
By this means in case of a fire occurring in the room or other place the fuse would
be ignited and would explode the charge and thereby produce an alarm.
When the apparatus is to be used as a fire extinguisher as well as an alarm the
moveable portion of the case or holder is so arranged that it is forced open by the
explosion of the charge and operates any suitable means for extinguishing a fire, such
as a weight or spring arranged to turn on a supply of water.
Or the said apparatus can be caused to break a glass vessel containing a suitable
chemical fire-extinguishing liquid.
It will be obvious that several of my improved apparatuses can be employed so as to
produce a number of alarms in succession; also the apparatus can if required be caused
to sound a bell.

Extinguishing Fires.
I, FRANCIS GOODALL WRIGHT, of 66, Kennington Road, in the county of Surrey,
Blacksmith, do hereby declare the nature of this 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 means for giving an alarm in case of fire, the said means
being also applicable for use in connection with apparatus for extinguishing fire.
in carrying out my invention 1 make use of an explosive in a suitable form, and I
find it advantageous to provide a case or holder formed in two parts to receive the
explosive, one part of the said case or holder being adapted to be fixed in any
convenient position while the other part is movable relatively to the fixed part.
In connection with the explosive I employ a fuse extending to any part or parts
where fire is liable to break out, so that in case of fire the fuse will become ignited
and discharge the explosive thereby producing an alarm.
In the accompanying drawing,
Figure 1 is an elevation of my improved apparatus arranged in conjunction with
the cock of a water supply pipe; and,
Figure 2 is a plan of the same.
a, bure the two parts of the case or holder, the former of which is adapted to be
secured to the wall of a room or in some other suitable position while the latter is
pivotted to the part a at c.
As shown the part a is provided with a slot or recess d at one end and the part b is
also formed with a hollow e as shown most clearly by the dotted lines in Figure 1, so
that when the two parts are closed together a chamber will be formed for containing
the explosive.
g is a fuso which extends from any part or parts of a room or building to the interior
of the chamber f where it is attached to the explosive.
With this arrangement it is obvious that if the fuse is ignited fire will be
communicated to the explosive to discharge the same, the force of the explosion giving
an alarm and moving the arm or part & for instance to the position shown in dotted
lines in Figure 1.
When it is desired to turn on a supply of water at the same time, that the alarm is
given, I utilize the motion of the arm & for the purpose.
To accomplish this I advantageously provide the arm b with an extension h and in
connection with this extension I employ a weighted lever i secured upon the plug of
a cock which controls a water supply. One end of this lever normally bears
against the extension and maintains the cock closed, when, howover the arm bis
gioved the lever i is drawn down by the weight thereby opening the cock.

page_text: In some cases the apparatus may be arranged in conjunction with a glass vessel
containing a fluid chemical fire extinguisher, in such a manner that when the
arm is moved owing to an explosion it will strike the bottle and break it, thereby
liberating the contents.
It will be obvious that soveral of my improved apparatuses can be employed in
combination so as to produce a succession of signals, and the apparatus can, if desired,
be arranged to sound an electric or other bell.
I wish it understood that I do not limit my invention to the construction herein before
described as it is obvious that the same can be considerably modified; neither do I
confine myself to the application shown as the motion of the alarm apparatus can be
utilized in any convenient manner for turning on a water supply.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. Improved means or apparatus such as herein described, wherein an explosive is
employed for giving an alarm in case of fire.
2. Apparatus for giving an alarm in case of fire comprising two parts which are
movable relatively to each other and which contain a chamber between them adapted
to receive an explosive, substantially as, and for the purpose, described.
3. In apparatus wherein an explosive is employed for giving an alarm in case of
fire, utilizing the force of the explosion for turning on a water supply or for causing the
discharge of a liquid, substantially as described.
4. The manufacture and use of the improved apparatus herein before described and
illustrated in the accompanying drawing for giving an alarm in case of fire or for
permitting the discharge of liquid onto the flames.
