Improvements in Water Sprinkling Devices for Extinguishing
Fires.
A communication to me from CHARLES LINGER, of Reichenberg, Bohemia, in the
Empire of Austria, Copper and Hard-ware Merchant.
I, EDMUND EDWARDS, of the Firm of Edwards and Co., Chartered Patent Agents
and Engineers, of 65 and 66, Chancery Lane, in the County of Middlesex, 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, and accompanying drawing, that is to say :-
The sprinkling roses of the fire-extinguishing devices heretofore ordinarily used,
have the objection that when the rose comes into operation some part of the device
becomes loose and is liable to be lost, thereby causing expensive repairs. Moreover,
the distribution of water by such roses is imperfect, as the water generally
sprinkles an annular surface only of the floor, the space directly below the
rose not being touched by it.
an
The present invention does away with these inconveniences and secures
absolutely certain effect. It is illustrated in the accompanying drawing, similar
letters of reference indicating corresponding parts in the several figures.
The improved device consists essentially of a cone c serving at the same time as
a valve to close the water supply pipe a, and to distribute the water, as illustrated
in Figures 1, 2, 6, and 7. In its normal position the cone closes the orifice of the
water supply pipe a, being pressed against this orifice by a lever b held in its
position by an easily fusible composition d.
When a fire breaks out, the heat acts upon this composition, whereby the
lever b and the cone a are released. The lever swings downward, and the cone
moves in the same direction until it strikes against the stop e (as shown
in Figure 4). The water flows out in the form of a uniform drizzling rain,
owing to the particular shape of the cone.
As shown in Figures 2 and 5 the cone has a rim c¹ curved upwards and -
provided with slits, whereby the water as it flows out is not only distributed
uniformly, but also sprinkles the space below the rose.
Of course, it will be understood that the easily fusible composition d may be
formed and arranged in any suitable manner; for instance, a ring may be
employed, the ends of which are held together by an easily fusible material
(Figures 1, 2, and 3), or the ring made be made entirely of an easily fusible material.
Instead of a ring a simple strip may be employed, as shown in Figures 6 and 7.
To press the cone against the valve-seat an adjusting screw f is provided
(Figure 2), or the guide-spindle of the cone itself is arranged in such a manner as
to be used as an adjusting screw, (Figure 7). In the latter case the spindle is
screwed into the cone and may be turned by means of a pointed instrument in
order to press the cone against the valve seat.
Moreover, the lever b may be formed as a double-armed lever, the free end of
which is connected with a draw-line or the like, by means of which the valve may
be closed from a distant place.

page_text: Having now particularly described and ascertained the nature of the said
invention, and in what manner the same is to be performed, I declare that what I
claim is :-
A rose for fire-extinguishing devices, characterized by a cone (c) closing the
orifice of the water supply pipė (a) by means of a lever (6) held in its position by
an easily fusible composition (d), the said cone producing when released, by means
of its rim c¹, provided with slits, a uniform distribution of the water, and being held
in its position by a stop (e), substantially as described and illustrated.
