Improvements in Fire Extinguishing Apparatus.
I, THOMAS ANDREW READY, of New York City, in the County and State of New
York, United States of America, 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 fire extinguishing apparatus and it has for its object to
provide a nozzle capable of receiving and discharging water from several sources,
such for instance as from a number of fire engines thus forming what may be termed
a battery. A further object is to mount the nozzle on a carriage so that it may be
readily moved from place to place; and a further object is to provide a simple
means whereby the nozzle may be easily rocked on its trunnions to direct a stream
of water in the desired direction.
I will describe a fire battery embodying my invention and then point out the
novel features in the appended claims.
Reference is to be had to the accompanying drawings forming a part of this
specification in which similar characters of reference indicate corresponding parts in
all the views.
Figure is a sectional elevation of a fire battery embodying my invention;
Figure 2 is a top plan view thereof; and
Figure 3 is a rear elevation.
Referring to the drawings, 1 designates a carriage mounted on wheels 2 and
having the trail stocks 3. Mounted on the carriage 1 is a nozzle 4. This nozzle is
tapered from its inlet to its outlet end and has trunnion bearings in the carriage
so that it may be rocked vertically. The rear end of the nozzle has a number
of inlet nipples 7 to which hose may be attached when the device is in use. I have
here shewn three of these inlet nipples but it is obvious that more or less may be
employed without departing from the spirit of my invention.
One of the trunnions 5 is extended through the side of the carriage and on this
extended end is a pinion 8 meshing with an intermediate pinion 9 which meshes with
a pinion 10 mounted to rotate on a stud extended from the carriage, and to this
pinion 10 is attached a hand wheel 11 having radial hand pieces 12. A dog 13 is
pivotally connected to the carriage and is designed to engage with one of the pinions.
As here shewn it is constructed to engage with the intermediate gear. The dog is
provided with a handle 14 so that when it is desired to rock the nozzle, the dog may
be disengaged from the pinion by pulling downward on the handle 14, which is
placed within easy reach of a person operating the hand wheel. Of course when the
nozzle is directed in the desired direction the dog will be replaced in connection with
the pinion and then the device may be left without attention so long as it is desired
to throw water in the direction in which the nozzle is pointed.
Movable transversely through openings in the side pieces of the carriage and
adapted to engage with the spokes of the wheel are blocking rods 15 and extended
outward from the spokes of the wheels are hand rods 16. These hand rods 16 are
placed near the outer ends of the spokes and are designed to be grasped by men when
it is desired to move the apparatus from place to place.

page_text: At the ends of the trail stocks are iron loops 17 with which straps or ropes may be
engaged when it is desired to run the apparatus down a stairway into a cellar or
basement, should the fire in such cellar or basement be too hot or fierce to allow the
entrance of firemen with the ordinary hand nozzles. To the cross bar 18 connecting
the ends of the trail stocks is fastened a ring 19, from which a rope or the like may
be extended to a connection with a fire engine or hose carriage to move the
apparatus to and from a fire.
In operation, after the apparatus shall have been placed in the desired position,
the wheels will be blocked by pushing the rods 15 into engagement with the wheel
spokes, as indicated in Figure 2; and after placing any desired number of hose 20 in
connection with the nozzle, the nozzle will be turned in the direction in which it is
desired to throw the stream, by rotating the hand wheel 11. By means of this hand
wheel and chain of gearing it is obvious that the nozzle may be operated by one
person.
It is obvious that when two or more engines are connected to the nozzle, a
stream of water may be thrown with great force and to a great height.
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. A fire battery, comprising a carriage having trail stocks, loops on the lower ends
of said trail stocks wheels on which the carriage is mounted, bars extending outward
from the spokes of said wheels, blocking devices carried by the carriage and movable
into engagement with spokes of the wheels, a nozzle having trunnion bearings in
said carriage, and means for adjusting the said nozzle, substantially as specified.
2. A fire battery, comprising a carriage having a trail stock, wheels on which the
carriage is mounted, a nozzle mounted to swing in said carriage, mechanism for
raising a lowering the nozzle, and inlet nipples at the rear end of said nozzle for
connection with water hose, substantially as specified.
3. A fire battery, comprising a carriage having trail stocks, loops on the lower ends
of said trail stocks, wheels on which the carriage is mounted and bars extended
outward from the spokes of the said wheels, blocking devices carried by the carriage
and movable into engagement with spokes of the wheel, a nozzle having trunnion
bearings in said carriage, a pinion on an extended end of one of the trunnions, a
hand wheel mounted to rotate on a stud extended from the carriage, a pinion
attached to said hand wheel, an intermediate pinion connecting the first two
mentioned pinions, and a locking dog for engaging with one of the pinions,
substantially as specified.
