stroys Fire-SOme of It's Uses.
From the New York Journal OF Commerce.
The new nozzle is known as the Ball
Nozzle" and from the tests so far made it
bids fair to revOlutionize the equipment
of fire extinguishers The ball nozzle has
already been adopted by the fire DEPART
ment in Des Moines, the home of the in
ventor. After witnessing the working of
the nozzle to-day Chief Bonner said that
the New York department would also have
to have it. In view Of the serious confa-
grations that frequently visit This city
this new discovery is Of special interest.
IL Is purely a discovery and not an in
vention.
Three years ago Charles V. Pollock, a
resident of Des Moines, while experiment.
ing with an ordinary lawn sprinkler dis
covered secret of nature which prom
ises far reaching results.
Mr.. Pollock found that a ball placed
loosely in bell shaped nozzle without
anything to hold it in position would re-
slst all pressure of water and create a
spray, and that no possible pressure would
dislodge the ball.
Following this up and searching out
| the practical uses to which his discovery
might be applied Mr.. Pollock found that It
will serve many purposes Of human neces-
sity, most important of which Is that of
adding to the present fire equipments a
spray of such powerful effect that it is
claimed where fire departments are prompt
in reaching conhagrations there will be
no longer necessity for loss of life either
from suffocation or fire.
The exhibition of the nozzle is to be pub
lie next week and thereafter. The space
| devoted to it is quite an acre in extent. In
one corner of the room is an electric foun-
tain, thirty feet across, sending upward
and outward through ball nozzle thin
sheet of water in the form Of an inverted
cone, which constantly changes from one
prisgnatc color to another, until the
gamut OF the rainbow has been run.
West Of the fountain is a house, the walls
of which consist of plate glass, in size 50
feet by Is feet and 10 feet high. 1t is here
that the life and property saving qualities
of the new nozzle are shown. A real fire
man, armed with a full sixed fire ball noz-
zle enters the structure and displays its
workings.
The wall nearest Fourteenth street ex-
tending Is feet from Broadway, is de-
voted to Spanish landscape, containing
forests, lakes, chateaux and pleasure
grounds. There is also a Spanish pavil-
ion, Moorish arches and red thing Fur
Their to the west is a two-story Spanish
cottage with double piazzas. Facing the
center of the floor is seen a clever ar
rangement of booths constructed in the
prevailing Spanish design. In the center
of the room stands a large treee equipped
with a stand pipe and ball nozzle. This
is used to show the way in which the
tree may have a gentle shower, which
falls on the leaves from above as nature
intended.
The intermediate spaces are decorated
with orange trees, palms, evergreens and
ivy, and other creeping vines entwine
the Moresque columns and cling to the
red roof tiles.
The best quality claimed for the new
nozzle is that it is an effective protector
against smoke. The spray from the
nozzle creates a solid wall of water be-
tween the fireman and the smoke and
flame, enabling him to pursue it to it's
source no matter where 1t is in a struct-
ure, cover large area and thus rescue
people who might otherwise perish. 1t is
also claimed for the ball nozzle that the
force from it while great enough to
duench flames, is not sufficient to cause
unnecessary destruction of interior prop
erty
Another application of the nozzle is, it is
claimed, that of making lumber yards
practically fire proof. 1t has been found
that they can be equipped with stand
pipes every 100 square feet, and that by
turning on the water from the outside
the entire yard may be practically flooded
in a few moments.
Another use to which the ball nozzle
may be put is in connection with ventila-
ton, as q ball placed in a bell produces
the same effect against the pressure of
the air as it does against the pressure of
water. 1t is expected to become an i'm
nortant feature in sanitary regulations
for disseminating disnfectants and fresh
air in close rooms and unhealthy places.
The new device seems especially adapted
for theaters, public halls, educational edi-
fees. hotels. apartments, houses, fac
tories. 1t would also prove valuable ac-
ouisition to have on a stage when an ex-
! igencv occurs such as the other night in
Harlem Theater, when an actors costume
ignited and he was fatally burned be-
fore the gaze of the startled audience.
