Improved Automatically Operated Sprinkling Device for Extinguish-
ing Fire.
I, CHRISTIAN LINSER, of Reichenberg, in Bohemia, in the Empire of Austria,
Manufacturer, 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:-
This invention relates to a sprinkling device for sprinkling the room in which
it is placed in all directions in case of a fire, the valve being set free by the heat
in the room.
The annexed drawing represents the sprinkling device in which Fig. I is a
section showing the valve closed.
Fig. II is an elevation showing the valve opened.
Fig. III shows two parts in detail.
Fig. IV is an upper view of the sprinkling crown.
The arrangement is as follows:--
On the lower end of the short tube a connected with the water pipe is a plate b
which forms a seat for the valve and is fastened tightly in place by means of a
screw collar d. Upon the screw collar da frame e is screwed in the lower part
of which the valve cone e acting also as a sprinkling crown can move vertically.
This valve cone is provided on its periphery with radial openings f and g of

formed projecting parts and are of alternately different lengths and bent
upwards at different angles to the conical surface m.
The longer projections h are for instance bent more upward than the shorter
ones i.
In consequence of the peculiar formation of the sprinkling crown the water
flowing out of the short tube a is divided by the conical surface m and the pro-
jections of the sprinkling crown into a number of fine jets and spreads in all
directions some of these jets being directed by the openings f and g in different
directions to the floor and others by the shorter projections nearly horizontally
and the remainder by the longer projections h are directed upwards.
Previously in order that an automatic sprinkler would act at the moment of
danger a soldered stopper was generally used, but the same has the disadvantage
that at the moment it gives way and the water begins to sprinkle the soldering
grows hard again and a further opening of the sprinkling device is not possible.
In order to prevent this disadvantage in this invention a beam is arranged
hinged on a knife bearing k of the frame c which leans against the bolt n of the
sprinkling crown and is connected with the frame c by the following arrange-
ment.
In the slotted end o on the right of the frame a plater shown in detail in
Fig. 3 is arranged which has an opening whilst in the right hand end of the

beam a similar plate is arranged having also an opening .
plate a second plate y is soldered with soft soldering material and through the
two openings s and a strip z of suitable material is inserted, the one end of which

page_text: is supported by the plate y. The strip z possesses therefore three supporting
points and prevents the plates and p from separating so that the sprinkling
crown is pressed tightly against its valve seat. If the soldering between the
plates and is melted by the heat, the plate y slides a little downwards in
consequence of the water pressure on the crown. But even a slight downward
movement of the plate brings the strip z into an oblique position so that it
slides out and sets the closure free so that the beam 7 takes the position shown in
Fig. 2 and the water can flow out from the short tube a.
Having now particularly described and ascertained the nature of my invention
and in what manner the same is to be performed I declare that what I claim is:-
1. An improved automatically operated sprinkling device for extinguishing
fire having a sprinkling crown e the periphery of which is provided with open-
ings of different depth f and g and projections and of different length bent
upwards at varying angles for the purpose of dividing the water flowing on the
surface m into many small jets and giving these jets different directions of flow.
2. An improved sprinkling device as in Claim 1 having a perforated plate r
hung in the frame of the sprinkling crown and a second perforated plate ?
hung in the beam 7 supporting the sprinkling crown to which plate ca support-
ing plate y is suitably soldered through which two plates and a strip of
suitable material supported by the plate y is put, for the purpose of allowing
the sprinkling crown to operate as soon as the solder of the plate y is melted and
the strip deprived of its support.
