Improvements in Fire Extinguishing Apparatus and Carriages
for the same,
JAMES CADOUX HUDSON, 75, Upper Ground Street, Blackfriars Road,
London, Engineer, do hereby declare the nature of this invention to be as
follows:
My invention has for its object improvements in arranging light carriages for
conveying firemen to a fire and at the same time carrying a supply of water or
other liquid and apparatus by which a line of hose can be immediately run into a
building and a jet of water thrown upon the fire without delay in attaching to
water mains or coupling up suction pipes and such connections as in ordinary
manual engines or steamers. I provide means of replenishing and continuing the
supply of water to the jet; and I provide accommodation for carrying other
hose, branchpipes, standpipes, ladders, and such appliances as are generally carried
on a hose cart or tender so as to attach to water mains which will supplement or
continue the attack until the fire is subdued or larger and more powerful appliances
arrive.
In four wheeled vehicles I construct a carriage similar to an ordinary manual
engine with the works removed, and in the tub or body I place one or two or more
cylindrical vessels containing water, or water with chemicals in solution-im-
mediately above these vessels or in the side pockets I place smaller flasks or
cylindrical vessels, containing air or gas in compression. On the upper part of
carriage and at rear of the hose box I place a reel containing hose pipe. A
connection is made between the lower part of water vessels and the centre of reel,
at which centre is a swivelling joint.
A connection is made between the smaller vessels and the water vessels, and
when required air or gas under pressure is admitted, forcing the water
up through hose pipe on reel and through to the jet--the hose can be
rull off the reel and the jet controlled by a tap at the branchpipe
end. At the rear of the carriage I place a pump with double cylinders
and worked by a double ended lever placed transversely to the centre line of
carriage; or other form of pump can be used. The suction inlet to pump projects
at rear of carriage; and to this I can connect an ordinary suction pipe or a hose
pipe connected to a water main. The delivery of pump is connected to the water
vessels.
Thus these vessels can be recharged with water by means of the pump drawing
through suction pipe or by water passing from main. By working the vessels
alternately a continuous supply can be delivered to the reel and hose pipe until the
air or gas in the smaller vessels is exhausted.
Or the hose can be supplied directly by the pump with or without passing to the
water vessels, or can be run to the hose directly from the water mains the
connection being made thereto whilst the vessels are exhausting.
The air supply is governed by a reducing valve to give a constant pressure in

page_text: the water vessels, and cocks or valves govern the supply of water to and from the
vessels and pump and to the hose. The desired pressure in the water vessels
can also be obtained in a similar manner to the ordinary arrangement common to
chemical engines.
The air vessels can be charged by an air pump, or the pump at rear of engine
can be used for this purpose.
In the first case by pumping air into the larger and smaller air vessels and
further compressing this air by pumping water into the water vessel and displacing
the air therein into the air vessel.
The hose box of the carriage described may be partly cut away to give space for
the reel, the remainder of the box being used for the ordinary equipment of hose,
standpipes, and other appliances, the top of box provides sitting accommodation
for firemen. Other forms of carriages may be used and one or more water and air
vessels with pump and other appliances may be fitted on a two wheeled cart.
These arrangements may be used separately or combined.
Scaling ladders may be fitted to sides of hose box and a brake also fitted. I
also fit the water vessels with a safety valve to prevent over pressure through
the air vessels leaking off. The air vessels may be shut off entirely from the water
vessels except when the jet is about to be used-or the desired pressure of air or
gas may be maintained in the water vessels keeping them ready for use.
I can
surround the water vessels with non-conducting materials to prevent freezing, and
for especially cold climates I provide means for keeping the water in the vessels
warm by an oil lamp and hot air pipe or similar device.
Such heating arrangement may be used to prevent the water freezing by the
expansion of the air or gas when pressure is turned on. On the carriage I also
provide boxes or pockets to contain an ambulance case for first aid. I also
can place similar appliances and arrangements on a similar scale on a
two wheeled cart. I also can arrange and combine such apparatus on such four
wheeled carriage and escape as is shewn & described in Patent No. 5330 and granted
to me Mar. 14th 1894.

Improvements in Fire Extinguishing Apparatus and Carriages
for the same.
JAMES CADOUX HUDSON, 75, Upper Ground Street, Blackfriars Road,
London, S.E., Engineer, 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:-
My invention has for its object improvements in arranging light carriages for
conveying firemen to a fire and at the same time carrying a supply of water or
other liquid and apparatus by which a line of hose can be immediately run into a
building and a jet of water thrown upon the fire without delay in attaching to
water mains or coupling up suction pipes and such connections as in ordinary
manual engines or steamers. I provide means of replenishing and continuing the
supply of water to the jet and I provide accomodation for carrying other
hose, branchpipes, standpipes, ladders, and such appliances as are generally carried
on a hose cart or tender so as to attach to water mains which will supplement or
continue the attack until the fire is subdued or larger and more powerful appliances
arrive.

and granted to me March 14th 1894.
In order that my said invention may be most fully understood and readily carried
into effect, I will proceed to describe the drawings hereunto annexed.

page_text: DESCRIPTION OF DRAWINGS.
Fig. 1 is a side elevation of a four wheeled carriage fitted with appliances
according to my improvements.
Fig. 2 is a sectional plan of same.
Fig. 3 is an end elevation of same.
Fig. 4 is a sectional end elevation.
Fig. 5 is a side elevation of a two wheeled cart fitted with appliances according
to my improvements.
Fig. 6 is an end elevation of same.
Fig. 7 is the side elevation of a four wheeled carriage fitted with appliances
according to my improvements also arranged to carry a telescopic fire escape in
a manner similar to Patent No. 5330 and granted to me in the year 1894.
Fig. 8 is an end elevation of same.
Fig. 9 is the side elevation of a two wheeled cart fitted with appliances according
to my improvements and carrying a fire escape in a manner similar to Patent
No. 2841 and granted to me in the year 1889, and Patent No. 2696 granted to me
in the year 1892.
Fig. 10 is an end elevation of same.
Fig. 11 is a side elevation of a two wheeled cart fitted with appliances according
to my improvements and arranged to carry a fire escape as in Patent No. 6108
and granted to me in the year 1897.
Fig. 12 is an end elevation of the same.
In these figures similar letters refer to similar parts.
In Figs. 1, 2, 3 and 4 (A) is the body of the carriage, (B) the hose box which
contains hose, branchpipes, standpipes and the like and also provides seating
accommodation for firemen and driver-(C, C) are side pockets or boxes, (D) the
running wheels, (D) the carriage springs with axles; (E) the fore locking carriage
all of somewhat similar construction to an ordinary manual engine although the
form of carriage may be varied to suit various requirements-(E, F) are cylinders
or vessels containing water or water and chemicals in solution. These
cylinders (F,F,) are carried in the body (A,) of carriage or other convenient position
and may be packed with non-conducting material to exclude frost-(G, G) are
flasks or cylinders charged with air or gas under compression and carried in the
side pockets (C, C). The cylinders (F, F) and flasks (G, G) are connected by
pipe (H) and the connection controlled by valve (I).
When air or gas under pressure in flask (G) is allowed by opening the valve (I,)
to enter the water cylinder (F,) the water therein contained is forced out when
desired and delivered into the hose (K) contained on the reel (L) by passing
through the pipe (0) and swivelling joint (P) at centre of reel.
Thus on arriving at a fire the firemen can at once enter a building dragging the
hose (K) off the reel (L) and obtain a jet of water to extinguish fire without
delay.
A double cylinder pump (Q) placed at back of carriage or in any other con-
venient position worked by lever (R) and having suction inlet branch (S) is
connected on its delivery side to the water cylinders (F, F) and the delivery
pipe (0) by a branch (T) and pipes (U) (N) (M). Three way cocks or valves (V)
control the discharge from the pump (Q) which then may either deliver into the
water vessels (F, F) or directly into the delivery hose pipe (0).
Safety valves (J,J) fitted on the water cylinders (F,F) prevent over pressure
which might be caused by air or gas from the cylinder leaking off when not in
use. The flasks (G) are charged by an air pump or by the use of the pump (Q) as
already explained.
Scaling ladders (W) can be fitted to side of hose box (B). A brake (X) can also
be fitted.
Instead of expelling the water from vessels (F,F) by means of compressed air
or gas, these vessels may be charged and discharged as in an ordinary chemical
engine.

page_text: In very cold climates I fit a lamp (Y) at (Z) or in convenient position to exclude
frost from vessels (F, F).
In Figs. 5 and 6 shewing a two wheeled cart fitted with my improved arrange-
ment the water vessels (F, F) or chemical engines are placed in body of cart-the
air flasks (G) in pockets at side. The pump at front of cart and the reel (L) at
rear. The upper part of body (32) is fitted with lids and carry other hose, stand-
pipes, branchpipes and the like.
Figs. 7 and 8 shew a four wheeled carriage similar to Figs. 1 to 4 and carrying
a fire escape (A') which can be very readily detached when required and the
extinguishing apparatus and the fire escape worked independantly.
Figs. 9, 10, 11 and 12 shew other arrangements of two wheeled carts carrying
the improved appliances and a fire escape.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is:-
Firstly. The arrangement of four or two wheeled carriages to convey firemen
and having a vessel or vessels containing water or water and chemicals in solution
and with arrangements for discharging same by apparatus described and having
necessary hose pipe, and reel or frame also carrying hand pump for recharging
vessels or maintaining jet and with accommodation for hydrant fittings and hose
pipes all for the purposes stated and as illustrated and described.
Secondly. The arrangement of such four or two wheeled carriages in connection
with a fire escape or scaling ladders for the purposes stated and as illustrated and
described.
Thirdly. The arrangement of such four or two wheeled carriages in connection
with parts or the whole of such apparatus as illustrated and described.
Fourthly. The arrangement for protecting from frost the vessels of chemical
engines or vessels containing water or water and chemicals discharged by com-
pressed air or gas as illustrated and described.
