PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Extinguishing Fire.
I, JAMES COMPTON MERRYWEATHER of Greenwich Road, S.E. in the
County of Kent, Engineer, do hereby declare the nature of this invention to be as.
follows:-
-
For the purpose of augmenting the pressure of water issuing from a pipe in order
to throw a jet, I attach a pump, preferably rotative, to the outlet or hydrant, but I
provide a second outlet in order that in the event of only one person being available
to use the hydrant water may be delivered without passing through the pump.
though at a lower pressure. A cap is provided to close the outlet to which hose is
not attached.

COMPLETE SPECIFICATION.
Improvements in Apparatus for Extinguishing Fire.
I, JAMES COMPTON MERRY WEATHER of Greenwich Road, S.E. in the
County of Kent, 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:—
For the purpose of augmenting the pressure of water issuing from a pipe in
order to throw a jet, I attach a pump preferably rotative, to the outlet or hydrant,
but I provide a second outlet in order that in the event of only one person being
available to use the hydrant, water may be delivered without passing through the
pump though at a lower pressure. A cap is provided to close the outlet to which
hose is not attached.
In the accompanying sheet of drawings,-
Figure 1, is a front elevation; and Figure 2, is a side elevation of the apparatus..
In Figures 1 and 2, A, is the pipe or main carrying a supply of water for fire
protective purposes. B, is the pump, in this case of the rotary class. C, is the
hydrant with two outlets D & E.
The outlet D is screwed for the attachment of hose, and the outlet E is connected
to the suction inlet of pump by pipe F.
G, is the delivery pipe of the pump terminating in a screwed outlet H.
Each of the screwed outlets are shewn with blank caps attached.
K, is the handle of the pump.
For the purpose of augmenting the pressure of water in the main A to enable a
powerful jet to be thrown for fire extinguishing purposes, a length of hose is.
attached to the oulet H, the hydrant C is opened, the handle K of the pump is
then rotated and the water is delivered at an increased pressure through the outlet H
and into the hose.
In cases where there is only one person available the hose is attached to the
outlet D, the outlet H being closed by a blank cap, and the pump of course being
left inactive.

page_text: 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 an arrangement of apparatus for extinguishing fire; the combination of a
pump with its suction inlet attached to an outlet on a firemain for the purpose of
increasing or augmenting the pressure of water already in the firemain, substantially
as described and set forth in the accompanying sheet of drawings.
Dated this 2nd day of November 1894.
