PROVISIONAL SPECIFICATION.
Improvements in Fire Engines or Extinguishers.
I, JOSEPH ELTON BOTT, of Brinnington Hall, Stockport, in the County of
Chester, Engineer, do hereby declare the nature of this invention to be as
follows:-
Heretofore it has been proposed to mount on a wheeled carriage one or more
cylinders containing alkaline water, and provided with suitable inlet and discharge
apertures, and having connected, therewith an air pump, by which air, at con-
siderable pressure, can be forced into the cylinder or cylinders to eject the water
therefrom.
According to my present invention I also mount one or more cylinders, preferably
two, on a wheeled carriage and furnish them with inlet and outlet passages, but..in
addition thereto, I place in the interior of each of said cylinders, a perforated
cylinder or container filled with alkali or other chemical matter or compound
inimical to fire, and I also mount on the carriage, preferably below and intermediate
of the aforesaid water containing cylinders, a cylinder containing compressed air
or gas, which is connected to the water cylinders by pipes fitted with cocks or
valves to enable intercommunication between the compressed air cylinder and either
or both of the water containing cylinders to be established or cut off as may be
desired. Thus by the employment of air or gas very highly compressed, a sufficient
supply can be carried by the engine for a long continued use, and by having the
perforated alkali or other chemical containing cylinders provided with a large
quantity of alkali or chemical, the water containing cylinders can be re-charged
many times with water and each charge sufficiently alkalized or chemically
impregnated.

COMPLETE SPECIFICATION.
Improvements in Fire Engines or Extinguishers.
I, JOSEPH ELTON BOTT, of Brinnington Hall, Stockport, in the County of
Chester, 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 :-
.Heretofore it has been proposed to mount on a wheeled carriage, one or more
cylinders containing alkaline water and provided with suitable inlet and discharge
apertures, and having connected therewith an air pump, by which air at consider-
able pressure can be forced into the cylinder or cylinders, to eject the water
therefrom.

According to my present invention I also mount one or more water.containing
cylinders, preferably two, on a wheeled carriage, and furnish them with inlet and
outlet passages, but in addition thereto I place in the interior of each of said
cylinders, a perforated cylinder or container filled with alkali or other chemical
matter or compound inimical to fire, or I may employ simple water.cylinders charged
with a large excess of alkali or other chemical matter inimical to fire, and I also
mount on the carriage, preferably intermediate of the aforesaid water containing
cylinders, a cylinder containing compressed air or gas, which is connected to the

page_text: water cylinders by pipes fitted with cocks or valves to enable intercommunication
between the compressed air cylinder and either or both of the water containing
cylinders to be established or cut off as may be desired. Thus, by the employment
of air or gas very highly compressed, a sufficient supply can be carried by the
engine for a long continued use, and by having the water containing cylinders 5
provided with-a-large quantity of alkhlú or Achemical, the said water containing
cylinders can be re-charged many times with water and each-charge sufficiently
alkalized or chemically impregnated.
said invention may be more clearly understood and readily
And in order that proceed, aided by the accompanying drawings, more fully
carried into effect, I
to describe the same.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is a side view, Figure 2 an end view, and Figure 3 a plan, of a fire
engine.constructed according to my invention.
Figure 4 is a longitudinal section of one of the water containing cylinders.
Figures 5 and 6 are respectively a longitudinal section and a cross section of a
water, containing cylinder showing a slight modification, and
Figure 7 is a plan of one of the paddles used with said modification drawn to a
larger scale.
In all the figures like parts are indicated by similar letters of reference:
11
The engine body a is supported on wheels b. b. c. c. in the ordinary manner.
dd are water containing cylinders, and e is a compressed air cylinder. These .
cylinders ad and are carried by metal supports a' fixed to the body a of the
enginė, the compressed air cylinder being preferably arranged intermediate of the
water cylinders, and the cylinders d d and are connected together by pipes fffitted 2
with cocks or valves f¹ƒ³, so as to enable either or both of the water cylinders to
be placed in communication with the compressed air cylinder or to be cut off
therefrom.
The water cylinders d d are each provided with a pressure gauge 'd' and with a
hose connection d. The front of the carriage is provided with two reelsg upon
which lengths of hose are coiled until wanted for use.
In the arrangement shown at Figures 1 to 4 the water cylinders d d are each
provided with a perforated cylinder or container d³, which is supplied with a large
quantity of alkali or other chemical matter or compound inimical to fire. These
perforated cylinders d are fixed to axes d' mounted in bearings in each end of the 3
oylinders dd, and these axes are each fitted at one end with a handle d", by which
they can be rotated so as to enable each charge of water to be quickly saturated
with the alkali or chemical matter or compound contained in the perforated
cylinders d'
In the modification represented at Figures 5, 6 and 7, I dispense with the "
perforated cylinders d' and charge the water cylinders d d directly with the alkali
or chemical matter or compound. In this latter case I provide the axes d' with a
number of paddles or stirrers de, preferably of diamond form, so as to effectually
stir the contents of the cylinders d d when the axes are revolved in either
direction.
To prepare the engine for use the cylinders d d are first charged with water and
with a large quantity of alkali or other chemical matter or compound inimical to
fire, and the cylinder e is filled with highly compressed air or gas; then, on the
engine being required for use, hose is connected to one or both of the cylinders dd,
and one or both of these latter are placed in communication: with the compressed
air cylinder e, the compressed air from which will force out the alkalinė or
chemically impregnated water through the hose.
The cylinders may be charged with water through the hose connection d³ or
through a specially provided orifice, and where the cylinders d d are used without
an internal perforated eylinder to contain the alkali or chemical matter or compound,
the cylinders d'd may be supplied with alkali or chemical: by removing the rear.ends
a

page_text: of such cylinders or through other orifices specially provided for such purpose, whilst
when using a perforated inner cylinder d', the alkali or chemical may be supplied
to the latter by first removing the rear end of the cylinder d and partially with
drawing the inner perforated cylinder d', which latter then receives its supply of
alkali or chemical through a suitable door (not shown) in the cylindrical part
thereof.

Any convenient means may however be adopted for enabling the cylinders d d, d³d³,
to be supplied with alkali or chemical. The compressed air cylinder e can be
supplied with its charge of highly compressed air or gas by a suitable connection
preferably at one of its ends..
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. In fire engines or extinguishers, the combination of a cylinder charged with
highly compressed air or gas, one or more water containing cylinders charged with
water, and with a large excess of alkali or chemical inimical to fire, suitable con-
nections between the water cylinders and the compressed air cylinder, cocks or
valves governing such connections, and hose connections to the water cylinders;
substantially as herein shown and described and for the purpose stated.
2. In fire engines or extinguishers, the combination of a cylinder charged with
highly compressed air or gas, one or more water containing cylinders, each provided
with an internal perforated cylinder charged with a large excess of alkali or
chemical inimical to fire, connections between the water cylinders and compressed.
air cylinder, cocks or valves governing such connections, and a hose connection
to each water cylinder, substantially as herein shown and described and for the
purpose stated.
3. In fire engines or extinguishers, the general combination and arrangement of
parts, substantially as herein shown and described.
