ALARM EXTINCTEUR OF FIRES IN CHIMNIES to be as follows:
Year: 1885

page_text: I DESIRÉ PUTZEYS of Brussels, in the Kingdom of Belgium, Gentleman, do
hereby declare the nature of my said invention for "ALARM EXTINCTEUR OF
FIRES IN CHIMNIES to be as follows:-
"
The object of this invention is the extinction of fires in chimnies and is based
on the principle of intercepting the draught in the chimney when a fire is discovered
and at the same time to develope or produce a certain quantity of sulphurous acid
in the chimney.
Thus on one hand the draught is suppressed and on the other a gas is produced
which will not maintain combustion, and together they evidently constitute a most
powerful combination for smothering almost immediately a fire in a chimney.
The two effects are produced at the same time by the simultaneous fall of two
suitable bodies suspended to one and the same chain, and which close up the
chimney at the upper and the lower parts, or at the upper part only, the upper
body at the same time allowing a certain quantity of Flower of Sulphur to escape
which.spreads itself and enters into combustion thus producing sulphurous acid.
Figures 1 and 2 of the annexed drawings show a perspective and a sectional
view respectively of the interior of a chimney and represent two different arrange-
ments of the Alarm-Extincteur, Figure 3 is a detail view of the upper cone, and
Figures 4 and 5 arrangements to be applied without chains and in the upper part
of a chimney only.
Over these
As shown in Figure 1, plates T T¹ formed with a large hole or aperture whose
diameter is nearly equal to the section of the chimney are fixed horizontally in the
masonry at suitable positions at the upper and lower part of the chimney. Fixed
to these plates or to the masonry in any convenient manner are standards S S¹
which carry two rollers RR, R¹ R¹ on suitable arms or branches.
rollers a chain P F is passed in the manner indicated, the chain being composed
partly of metal links P which are readily fusible, such for instance as lead placed
at a certain distance from each other, and partly of rods or single long links F of
iron. These readily fusible metal links or parts of a chain may be replaced or
substituted by links or lengths of leather, wood, hempen rope, etc: or the whole
chain may be made up of materials easily destroyed by fire.
At the upper and lower ends of the chain are hung the cones A A¹ at suitable
heights, the bases of the cones being somewhat larger than the holes or apertures

page_text: in the plates T T¹ which they close up at a given moment to stop the draught in
the chimney in which they thus form obturators.
The upper cone A should be heavier than the lower cone A¹ in consequence of
the weight of the chain P F, and in order to support the cones in the required
position a pin or small spindle X is passed through a link of the chain and its head
butts against the arm carrying the lower roller R¹.
The lower cone or obturator is a simple closed or solid cone, but the upper cone
is of special construction, being slightly truncated and open at that part. It is
provided with a small tube G passing through its axis in which is a rod H having
at its lower end the cover L and at its upper end the plug or stopper N. This
rod is suspended direct from the chain and thus keeps the cone A closed whilst it is
suspended.
The cone contains a certain quantity of Flowers of Sulphur between two thin
layers of sand, this being for the purpose of assisting the escape of the Sulphur
from the cone at the required time.
A short chain I attached to the upper end of the rod G, actuates, when stretched
or pulled, an elbow or bell crank lever E which is in connection with an electric
bell or other sound producer placed in a conspicuous position.
All the parts of the apparatus are of metal with the exception of the chain
which may be composed of other materials as before described.
The action of the apparatus is as follows:-
When a fire breaks out in a chimney, the heat causes the chain to break in one
The two cones A A' fall
or several places by melting the leaden links P.
immediately into the holes or apertures in the plates T T¹ and thus stop the
draught in the chimney..
At the same time the cover L being no longer held, also falls, whilst the plug
or stopper N closes up the opening G, and allows the sulphur to escape which
spreads in powder form in the chimney and enters into combustion which trans-
forms it into Sulphurous acid which smothers or extinguishes the fire. By the
fall of the cone A the short chain I is stretched or pulled upon and actuates the bell or
sound producer with which it is in connection thus giving warning of the presence
of fire.
The arrangement shown in Figure 2 differs from that above described in that
only the lower cone A¹ is suspended to the chain P F which at its upper end is
attached to a lever arm C resting on a small bracket K recessed into the masonry.
The lever CC is pivotted at Y on a transverse axis fitted in the chimney and on
its end C¹ is placed the rod H sliding freely in the tube G of the upper cone A
which is supported and held in position by the cover L fixed to the rod H.
cone A is similar in construction to that described with reference to Figure 1. The
rod H also provided with a plug or stopper N rises a certain distance, guided in
the socket a fitted in the chimney in any suitable manner.

The chain is guided centrally at the lower part of the chimney by the ring a¹
fitted in the chimney in a similar manner to the socket a.

In this arrangement the lower cone is heavier in this case than the upper one so
as to maintain the lever C C in a horizontal position and the cones in their
respective places, but when the chain is broken, the lower cone falls with the .part
of the chain attached and stops up the hole T¹, the lever CC pivots under the
weight of the upper cone A which acts as above described and spreading the
sulphur in the chimney.
Another arrangement of upper cone is shown in Figure 3. In this arrangement
the rod H is composed of two parts the upper part h on which the tube G is guided
being fixed in the socket a.

The lower part of the rod h¹ which rests on the lever CC is fixed to the cone
which in this case does not contain any Sulphur. The sulphur in this case is
placed in a small receiver B suspended at the end of the lever C C to which it is
also attached at the lower part by the short chain J and assists in overturning it
when the lever pivots under the weight of the, falling, cone....

page_text: The alarm bell is actuated in this case by a weight hung freely to the short
chain and resting on the cone A when not in action.
If required only one obturator need be employed namely; the upper one and in
this case the chain would be simply fastened to a hook in the lower part of the
chimney.
Another arrangement to be used only in the upper part of the chimney is shown
in Figure 4. In this case there is no chain and the cone A is fixed to the end of
a rod h guided in a socket fitted beneath the plate T. The lower end of the rod
rests on a small cup Q fitted in the chimney in a similar way to the socket, the
bottom of the cup being of easily fusible metal. If therefore the heat of the fire
melts the latter, the cone A falls and stops up the chimney.
In an arrangement shown in Figure 5 the cone is replaced by a sphere A retained
in crossed ribbons p easily destroyed by fire and being suspended in any convenient
manner above the funnel shaped plate T. The ribbons when destroyed by the
fire allow the escape of the sphere which by its fall into the plate stops the
chimney up.
Registers, doors, or dampers may be formed in front of the obturators so as to
permit free access to the apparatus.

page_text: I DESIRÉ PUTZEYS of Brussels in the Kingdom of Belgium, Gentleman, 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
The object of this invention is the extinction of fires in chimnies and is based
on the principle of intercepting the draught in the chimney when a fire is discovered
and at the same time to develope or produce a certain quantity of sulphurous acid
in the chimney.
Thus on one hand the draught is suppressed and on the other a gas is produced
which will not maintain combustion, and together they evidently constitute a most
powerful combination for smothering almost immediately a fire in a chimney.
The two effects are produced at the same time by the simultaneous fall of two
suitable bodies suspended to one and the same chain and which close up the
chimney at the upper and the lower parts or at the upper part only, the upper
body at the same time allowing a certain quantity of Flower of Sulphur to escape
which spreads itself and enters into combustion thus producing sulphurous acid.
Figures 1 and 2 of the annexed drawings show a perspective and a sectional view
respectively of the interior of a chimney and represent two different arrangements
of the Alarm-Extincteur. Figure 3 is a detail view of the upper cone, and
Figures 4 and 5 arrangements to be applied without chains and in the upper part
of a chimney only.
As shown in Figure 1, plates T¹, T¹, formed with a large hole or aperture whose
diameter is nearly equal to the section of the chimney are fixed horizontally in the
masonry at suitable positions at the upper and lower part of the chimney. Fixed
to these plates or to the masonry in any convenient manner are standards S S¹
which carry two rollers R R, R¹ R¹ on suitable arms or branches. Over these
rollers a chain P F is passed in the manner indicated, the chain being composed
partly of metal links P which are readily fusible, such for instance as lead placed
at a certain distance from each other and partly of rods or single long links F of
iron. These readily fusible metal links or parts of a chain may be replaced or
substituted by links or lengths of leather, wood, hempen rope, etc: or the whole
chain may be made up of materials easily destroyed by fire.
At the upper and lower ends of the chain are hung the cones A A¹ at suitable
heights, the bases of the cones being somewhat larger than the holes or apertures
in the plates T T which they close up at a given moment to stop the draught in
the chimney in which they thus form obturators.
The upper cone A should be heavier than the lower cone A¹ in consequence of
the weight of the chain P F, and in order to support the cones in the required
position a pin or small spindle X is passed through a link of the chain and its head
butts against the arm carrying the lower roller R¹.
The lower cone or obturator is a simple closed or solid cone, but the upper cone
is of special construction being slightly truncated and open at that part. It is
provided with a small tube G passing through its axis in which is a rod H having

page_text: at its lower end the cover L and at its upper end the plug or stopper N. This
rod is suspended direct from the chain and thus keeps the cone A closed whilst it
is suspended.
The cone contains a certain quantity of Flower of Sulphur between two thin
layers of sand, this being for the purpose of assisting the escape of the Sulphur
from the cone at the required time.
A short chain I attached to the upper end of the rod H actuates when stretched
or pulled, an elbow or bell crank lever E, which may be in connection with an
electric bell or other sound producer placed in a conspicuous position.
All the parts of the apparatus are of metal with the exception of the chain
which may be composed of other materials as before described.
The action of the apparatus is as follows:-
When a fire breaks out in a chimney, the heat causes the chain to break in one
or several places by melting the leaden links P. The two cones A A¹ fall
immediately into the holes or apertures in the plates T T' and, thus stop the
draught in the chimney.
At the same time the cover L being no longer held, also falls, whilst the plug
or stopper N closes up the opening G and allows the sulphur to escape,―spread
in powder form, in the chimney and enters into combustion which transforms it
into Sulphurous acid and smothers or extinguishes the fire. By the fall. of the
cone A the short chain I is stretched or pulled and may actuate a bell or sound
producer with which it is in connection thus giving warning of the presence
of fire.

The arrangement shown in Figure 2 differs from that above described in that
only the lower cone A¹ is suspended to the chain P F which at its upper end. is
attached to a lever arm C resting on a small bracket .K recessed into the masonry.
The lever CC is pivotted at y on a transverse axis fitted in the chimney and on
its end C¹ is placed the rod H sliding freely in the tube G of the upper cone A
which is supported and held in position by the cover L fixed to the rod H. The
cone A is similar in construction to that described with reference to Figure .1.
The rod H also provided with a plug or stopper N rises a certain distance guided
in the socket a fitted in the chimney in any suitable inanner.
The chain is guided centrally at the lower part of the chimney by the ring a¹
fitted in the chimney in a similar manner to the socket a.
In this arrangement the lower cone A¹ is heavier than the upper one so as to
maintain the lever C C in a horizontal position and the cones in their respective
places, but when the chain is broken the lower cone falls with the part of the
chain attached and stops up the hole T¹, the lever CC pivots under the weight of
the upper cone A which acts as above described and spreads the sulphur in the
chimney.

Another arrangement of upper cone is shown in Figure 3. In this arrangement
the rod H is composed of two parts the upper part h on which the tube G is guided
being fixed in the socket a.
The lower part h¹ of the rod H which rests on the lever C C' and is fixed to the
cone A which in this case does not contain any Sulphur; the sulphur being placed
in a small receiver B suspended at the end of the lever C C¹ to which it is also
attached at the lower part by the short chain J and assists in overturning it when
the lever pivots under the weight of the falling cone.
The alarm bell is actuated by a weight hung freely to its short chain I and
resting on the cone A when not in action.
If required only one obturator need be employed, namely; the upper one A
and plate T as shown in Figure 6 and in this case the chain PF would be simply
fastened to a hook in the lower part of the chimney, shown at Figure 7.
Another arrangement to be used only in the upper part of the chimney is shown
in Figure 4. In this case there is no chain and the cone A is fixed to the end of
a rod h guided in a socket fitted beneath the plate T. The lower end of the rod h
rests on a small cup Q fitted in the chimney in a similar way to the socket, the

page_text: bottom p¹ of the cup being of easily fusible metal. If therefore the heat of the
fire melts the latter, the cone A falls and stops up the chimney.
In an arrangement shown in Figure 5 the cone is replaced by a sphere A retained
in crossed ribbons p easily destroyed by fire and being suspended in any convenient
manner above the funnel shaped plate T. The ribbons when destroyed by the
fire allow the escape of the sphere which by its fall into the plate stops the
chimney up.
Registers, doors, or dampers may be formed in front of the obturators so as to
permit free access to the apparatus.

invention and in what manner the same is to be performed I declare that what
