Improvements in and relating to Portable Fire-extinguishing
Apparatus.
I, GEORGE CONSIDER HALE, of Kansas City, in the County of Jackson, and State
of Missouri, United States of America, Chief of Fire Department, do hereby
declare the nature of my invention for "IMPROVEMENTS IN AND RELATING TO
PORTABLE FIRE EXTINGUISHING APPARATUS" and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:-
My invention relates to improvements in portable water towers for conveniently.
handling a fire-hose in playing upon a fire, which will be hereinafter fully described
and claimed.
The primary object of my invention is to provide a portable water tower with an
improved aerial tower of very light but strong and substantial construction which is
so constructed and arranged that it can be conveniently and easily operated by one
attendant or operator standing at the base of the tower, the various manipulations
of the directing nozzle for the stream of water, such as lowering or raising the
nozzle vertically to a less or greater elevation, changing its vertical inclination, or
turning the same horizontally at any desired radius from the tower as its centre,
being easily and quickly accomplished by suitable contrivances, all of which are
within convenient reach of the single operator.
A further object of my invention is to utilize a line of the ordinary flexible fire-
hose to convey the stream of water to the directing nozzle, and thus avoid the use
of a metallic pipe or conduit which is objectionable, primarily, because the water is.
liable to freeze therein in the winter time; such line of flexible hose affording an
unobstructed direct water-way, free from screws, gearing etc., which is highly
desirable in an apparatus for throwing a stream of water under very great pressure
and at a high elevation upon a fire.
A further object of my invention is to provide a peculiar support for the line of
fire-hose to the directing nozzle, by which the line of hose is prevented from
"kinking" or becoming twisted or wrinkled when the directing nozzle is deflected
so as to throw the stream of water in a downwardly inclined direction, toward the
ground.
And my invention has further for its object to provide appliances and improve-
ments in various parts whereby efficiency in operation and convenience in manipula-
tion are materially increased.
The first part of my invention consists of a folding tower, pivoted at its lower
extremity to a truck, and constructed to receive within the same a metallic rigid.
hollow-mast which is supported by the tower and is arranged to telescope or slide
longitudinally with the same, an adjustable or movable nozzle carried by the upper
protruding end of said rigid, hollow-mast, and a line of flexible fire-hose passing
through the hollow rigid mast and connected to the directing nozzle, suitable
appliances being provided by telescoping the hollow rigid mast within the tower and
for manipulating the movable directing nozzle.
The second part of my invention consists of a contrivance for supporting the line
of flexible fire-hose at the point where it bends or curves when the movable directing
nozzle is deflected downward to throw a stream of water toward the ground, and in
a device for manipulating the directing nozzle. The nozzle proper is pivoted at or
near its base, so as to turn in a vertical plane or direction, to rigid supporting arms,
which are fixed to a vertical tubular sleeve which is fitted and supported on the upper
extremity of the hollow rigid mast. This sleeve is located exteriorily of the mast,

page_text: and to it is fixed a gear wheel, with which meshes a pinion on a vertical operating
shaft by means of which the sleeve can be turned horizontally to change the horizontal
radial position of the nozzle as may be desired, said operating shaft being fitted within
a tubular shaft which is supported on the tower proper and has a hand-wheel at its
lower extremity for conveniently manipulating the two shafts so as to rotate the
nozzle carrying sleeve horizontally.
The flexible fire-hose is extended beyond the hollow mast between the pair of rigid
arms provided for the support of the nozzle, and is connected to the latter at a point
in rear of its pivot, whereby the weight of the hose and the column of water therein
serves to normally turn the nozzle to a vertical position; but the operator is enabled
to overcome this tendency of the hose to turn the nozzle to an upright position, by
means of a cable attached to the free end of the nozzle, whereby the nozzle can be
turned to any desired vertical angle to direct the stream of water either upward,
downward, or horizontally, as may be desired. The support for preventing the
flexible hose from "kinking" or wrinkling consists of a saddle which is carried by
the nozzle, at or near its rear end, and is curved downwardly therefrom, said saddle
being thrown out of the path of the hose when the nozzle is inclined upwardly or
turned to a horizontal position but when the nozzle is deflected downward from its
pivot, the saddle is thrown against and in contact with the hose at the point where
the bend is made therein, thus forming a support for the hose at the bend.
My invention further consists in the combinations of devices and peculiar construc-
tion and arrangement of parts as will be hereinafter more fully described and
claimed.
As a full and complete understanding of my invention can be had to better
advantage by a detailed description thereof, I will now proceed to describe the
preferred embodiment of the invention which is illustrated in the accompanying
drawings, and in which :-

.
Like numerals of reference denote corresponding parts in all the figures of the
drawings.
1 is the truck of my improved portable water tower for conveniently handling a
line of flexible hose in playing upon a fire. This truck is mounted upon axles, 2, 3,
having the carrying wheels, 4, and intermediate of the fore axle and truck is a fifth-
wheel 5, suitable springs 6 being disposed between the axles and the ends of the
truck in any suitable manner well understood by those skilled in the art of building
heavy portable trucks.
7 is the foldable iower, proper, which consists of a series (preferably four in
number) of side pieces 7' which are arranged to form an inclosure or space square
in cross-section to receive the extensible mast, said side-pieces converging longitu-
dinally toward their upper ends as shown. The tower is strengthened by lattice-
work braces 8 secured to two, opposite sides of the side-pieces, and between said
pieces on the two sides of the tower which are free from the braces 8, are arranged
friction rolls 9 which serve the double purpose of strengthening the tower and

page_text: affording a sliding anti-friction bearing for the extensible mast. The tower is very
light, but at the same time it is built very strong and substantial, which are
desirable ends in a contrivance of this class.
The tower is carried by a stout steel shaft 10, which passes through and is firmly
secured to the base thereof, and this shaft is journalled in bearings 11 carried by the
upper ends of the supports or pillars 12, which are firmly and securely bolted to the
truck 1, near its front end. To the shaft 10, which constitutes the pivot on which
the tower turns to assume a vertical position, is rigidly secured a toothed segment or
gear 13, with the teeth of which meshes a horizontally movable rack-bar 14, said
rack-bar sliding in suitable guides on the truck and is secured or connected to the
piston rod 15 of a piston 16, which operates in a horizontal pressure cylinder 17,
said cylinder being located on the truck, at or near its rear end, and suitably
secured thereto, said rack and segment mechanism, together with the pressure-
cylinder and a chemical gas-generator, constituting the means for elevating the tower.
20 designates the extensible or telescopic mast, which is arranged to slide in
the tower. This mast consists of a cylindrical rigid tube 21, preferably of steel,
which is housed within a jacket or casing 22, which may be made of wood to
protect said steel tube; and the jacket (or the tubular metallic mast itself when
the jacket is omitted) is strengthened by means of longitudinal ribs 23, which are
arranged to ride against the friction rollers 9 in the tower. The upper end of the
tower is made very substantial by metallic plates 24, which are located and
arranged to permit the extensible mast to fit snugly between the same and thus
prevent any undue movement or swaying of the mast when extended, but said mast
is free to move between the sides of the tower, of which said plates form a part;
and on these plates are secured or journalled the shafts or guide rollers, 25, over
which pass the cables 26 for raising or lowering the mast. Two of these cables are
provided, one on one side of the tower and the other on the opposite side thereof,
and each cable has one end secured to the lower end of the extensible mast while it's
other end passes around one of the two winding drums; 27, which drums are carried
at the ends of a shaft 28 that is journailed in bearings at the pivoted end of the
tower, said shaft having a crank or cranks 29 for conveniently rotating the same.
30 is the directing nozzle, which is carried by the extensible mast at its extremė
upper end. This nozzle has trunnions 31 fornied thereon or secured thereto near
its extreine end, and these trunnions are fitted in the upper extremities of a pair of
supporting arms 32, so that the nozzle is free to turn in a vertical direction. The
rigid supporting arms are curved upwardly and forwardly beyond the upper end
of the mast, and said arms are bolted or otherwise rigidly secured at their lower
ends to a horizontally-rotating, vertical sleeve 33, said sleeve being fitted around
the extreme upper end of the hollow rigid mast, as shown in Figure 5. To the
lower end of the vertical sleeve is fixed a gear wheel 34, the hub of which rests on
a horizontal bracket or arm 35, that is rigidly fixed to the mast; and with said gear
wheel meshes a sleeved pinion 36, journalled in the outer end of the fixed bracket or
arm 35; said pinion having a squared shaft 37 secured axially thereto. This squared
shaft passes through a square or angular aperture in a cap or crown-piece 38 which
is fixed to the upper extremity of a vertical tubular shaft 39 which in turn is
supported; in any suitable manner, on the tower, at one side thereof, and has a hand
wheel 40 or other suitable contrivance at its lower extremity for conveniently rotating
the shafts 37' and 39. It is obvious when the shaft 39 is rotated by operating its
hand-wheel, that the square shaft 37 will rotate therewith by reason of the shaft 37
fitting snugly in the cap or crown-piece of the hollow tubular shaft 39, and that the
gear wheel and pinion will rotate the vertical sleeve to change the horizontal direction
of the stream thrown by the nozzle; and it is also obvious that the square shaft 37
will readily telescope within the tubular shaft when the mast is raised or lowered, the
sectional shaft 37, 39, thus accommodating itself without' manual manipulation thereof
to the extension or retraction of the mast, whereby the nozzle can be controlled when
it occupies any elevation, whether the mast is extended its full length, or only partly
extended or housed within the tower proper.

page_text: 41 designates the line of flexible fire-hose, of the ordinary kind or it may be
especially prepared by covering it with asbestos etc. with a view to resisting the action
of fire should the flames escape from the burning building or structure and surround
the tower when the apparatus is in use. This flexibie hose 41 is connected to the rear
end of the nozzle, as for instance by means of a coupling 42, and said hose passes
between the rigid supporting arms for the nozzle, and through the hollow metallic
mast and the tower, the lower extremity of the hose being connected to a water
chest 43 carried by the truck 1. 44 is the saddle which is carried by the movable
nozzle and constructed and arranged to support the flexible hose at the bend therein
when the nozzle is turned to a horizontal or downwardly inclined position. This
saddle, which is made of metal, is preferably made separate from the nozzle and
provided with a rib 45, by means of which the saddle is rigidly bolted to the lower
side of the nozzle. The saddle is curved or made segmental in cross section to snugly
fit against the hose and provide a firm support therefor; and said saddle is curved
longitudinally as shown, whereby the saddle is thrown or arranged at one side of and
out of contact with the hose when the nozzle is turned to a vertical position. When,
however, the nozzle is deflected from its vertical position, or turned to a horizontal
or downwardly inclined position, the curved saddle is thrown against and receives
the hose, so as to support the latter at the bend or angle and thus prevent the same
from "kinking" or wrinkling, as will be readily understood.
The weight of the hose and the column of water therein is sufficient to turn the
nozzle to an upright position, and in order to enable the operator to readily control
the vertical movement of the nozzle so that the angle of presentation of the nozzle to
the fire can be varied at pleasure, I have provided a cable 46, which is attached to the
nozzle at or near its outer end and extends to the base of the tower, so that it can be
readily and easily grasped by the operator. It will thus be seen that the various
appliances provided for projecting the mast beyond the tower after the latter has been
raised, for turning the nozzle horizontally, and for changing the vertical position or
angle of the nozzle, are all arranged at the base of the tower and within reach of an
attendant, who is thus enabled to manage the apparatus and change the position of the
nozzle according to the location of the fire. The tower proper is very rigidly and
firmly supported on the truck, and the position of the nozzle only is changed, which as
before stated can be easily and quickly accomplished by a single man, which is highly
advantageous over the ordinary apparatus in which the tower is mounted on a
horizontally-movable turn-table supported on a truck, to adjust which turn-table and
the tower carried thereby requires the combined efforts of a number of men. Besides,
such a tower is liable to sway or move but my tower is held very firmly and
rigidly in position. To the upper extremity of the mast, above the vertical,
horizontally-rotatable sleeve which carries the nozzle, is fixed a cap or crown-
piece 49, which serves to prevent upward play or displacement of the sleeve and
thus the gear wheels constantly mesh or gear with each other. This cap is pro-
vided at its upper end with a flaring or bell-shaped mouth, 49, in which the hose
is free to play back and forth when the nozzle is adjusted or its position changed. In
constructing a very high tower I contemplate providing a counterbalance for the line
of flexible hose and the column of water contained therein, in order to prevent too
great a strain on the coupling intermediate of the nozzle and hose and the supporting
contrivances for the nozzle. In the embodiment of my invention shown herein, this
counterbalance comprises two coiled springs, 5, which are arranged within the mast,
between the latter and the hose; one end of the springs being connected to the hose
and the opposite ends to the mast, as shown in Figure 5. These springs serve to take
up the weight of the hose and column of water contained therein, and thus relieve
the coupling, the pivots and other supporting devices of undue strain; but I do not
restrict myself to the particular form of counterbalance herein described, as it is
evident that changes therein can be made without departing from the spirit of my
invention.
The water chest is located at or near the middle of the truck, and is suitably
secured thereon, and this chest receives the water at one side under pressure from an

page_text: engine or engines, and delivers the water, under similar conditions, from the other side
into the flexible pipe-line that runs through the tower and connects with the directing
nozzle. This water chest has a "Siamese-connection," 51, at its receiving side, by
which the streams from two or three engines can be delivered to the water-chest,
which in turn supplies the line of hose with a very powerful stream for playing
upon the fire, which is highly desirable. The weight of this water-chest and its
contents when the apparatus is in use serves as a balance to hold the truck in
position.
The pressure-cylinder which constitutes a part of the mechanism for raising the
tower, as heretofore described, is supplied with compressed gas which is generated by
a combination of suitable chemicals in a reservoir or tank 52, which is located at the
extreme rear end of the truck 1, and supported on a platform 53, suitable contrivances
being provided for holding said tank or reservoir in position. The pressure-cylinder
and chemical tank or reservoir are connected by a suitable supply-pipe having a valve,
by opening which valve the compressed gas generated in the tank is admitted to the
front end of the cylinder, immediately after which the piston commences its backward
stroke and draws the rack-bar, which turns the segment and shaft to which the tower
is attached, thus lifting the tower very quickly to a vertical position and without
manual labour on the part of the attendant.
It may occur during a fire lasting quite a length of time that the tower will require
to be elevated and lowered such a number of times as to exhaust the supply of
chemicals contained in the tank or reservoir for generating the gas to operate the
piston in the pressure-cylinder; and in order to overcome this difficulty and provide
ineans whereby the tower can be operated by the pressure cylinder and its piston,
without manual labour, I have connected the water-chest and the gas-generating tank,
by means of a pipe 55, having a valve 56 said pipe entering the bottom of the gas-
generator, (see Figure 3). Should it become necessary to utilize the pressure of the
water in the water chest to operate the piston in the pressure-cylinder in order to raise
the tower, the valve in the water-way intermediate of the water-chest and gas-tank is
opened to admit water to the bottom of the tank, which as it ascends in the tank com-
presses the air therein and thus charges the tank with compressed air instead of gas,
which air will be compressed sufficiently to exert force or pressure enough on the
piston in the pressure-cylinder to operate the latter in raising the tower. This opera-
tion may be repeated as often as it is necessary to raise the tower, but the apparatus is
provided with a tank of such a capacity for generating sufficient gas to meet the
requirements of ordinary circumstances, and the means for compressing the air are
only employed in cases of an emergency.
The tower when elevated is maintained in such position by the pressure of the gas
(or air) in the pressure-cylinder against the piston, which thus draws the rack and
segment into such relative positions as to hold the tower upright. And I have also
provided means whereby the tower may be held in an inclined fixed position, which
means consist of a cable 57, which is attached at one end to the tower, near its upper
end, the other end of the cable passing around a winding drum or roller 58 located at
the rear end of the truck said drum being journalled in suitable bearings and having
pawl and ratchet mechanism 59 for limiting the axial movement of said drum.
Should it become desirable to hold the tower in an inclined position instead of a
vertical upright position the cable 57 is uncoiled a suitable distance from the drum to
permit the tower to be elevated to the desired position by the pressure of the gas or
air acting against the piston which controls the rack and segment. The pressure
of the gas on the piston, and the cable act against one another and thus hold the
tower in the desired position, the gas-pressure on the piston serving to lift the
tower while the cable checks the ascent of the tower beyond the limit deterinined by
the length of the cable which is uncoiled from the winding drum or roller.
The operation and advantages of my invention will be readily understood from the
foregoing description taken in connection with the drawings, and I do not therefore
deem it necessary to repeat the same here.
By constructing a tower as herein described and shown every essential advantage is

page_text: attained that a water tower of this class should have, among which may be enumerated
the following: A light but substantial aerial structure which can be expeditiously
raised or lowered without manual labour and which is very firmly and rigidly held in
place a direct water way which is free from obstructions in order to insure the
supply of a stream of water of undiminished force; to dispense with a metallic
conduit or pipe in which a large column of water is stored up and in which water
is liable to freeze in the winter time, and in lieu thereof utilize a line of ordinary
fire-hose in which the water is not liable to freeze; and to control and manipulate
the directing nozzle with ease from the base of the tower, so that the stream of
water can be thrown in any direction, either vertically, in any direction of the
compass, or at any desired elevation.
In Figure 6 of the drawing, I have illustrated a device for holding the truck in
a rigid, firm position, against any side or lateral play of its supporting springs, and
to accommodate the truck to any inclination of the surface on which the apparatus
stands.
This device consists of an extensible shank 60, one member 61 of which is con-
nected to the body of the truck and the other member 62 is adapted to engage one
of the axles of the apparatus. These members 61, 62, of the shank are provided
with right and left hand threads, with which engage similar threads on a rotatable
adjusting nut 63, which connects said members and when rotated serves to simul-
taneously adjust the same in opposite directions. The member 62 has the rigid jaw 64
which is constructed and proportioned to fit around the axle, and the other member
is pivoted, as at 65, to the body of the truck. Two of these jacks are provided,
one on each side at the front end of the truck, and when said jacks are not in use
they are folded or turned into horizontal position, alongside of the truck, (see
Figure 2), the free end of each jack resting on a fixed bracket 66. To use the jacks,
they are lowered to vertical positions and engaged with the front axle (see Figure 1),
after which the rotatable nuts are operated to draw the members together and thus
draw the truck 1 downward toward the axles, whereby the truck can be accommodated
to the surface of the street, and held very firmly and rigidly in a horizontal position,
the springs being relieved of all side play.
At the rear end of the truck. is arranged a vertical fixed support 67, consisting of
two standards 68 and a cross piece 69, and on this support rests the tower when it
is lowered to an approximately horizontal position substantially as indicated in
Figure 2.
I am aware that changes in the details in construction and form and proportion
of parts can be made without departing from the spirit or sacrificing the advantages
of my invention, and I would therefore have it understood that I do not confine
