Improvements in Portable Electrically Driven Pumps..
1, JAMES COMPTON MERRYWEATHER, of Greenwich Road, Greenwich, in the
County of Kent, Engineer, do hereby declare the nature of this invention to be as.
follows:-
The object of my invention is to construct a small domestic pumping engine for
fire extinguishing, or other purposes, driven by an electro motor, which can take
its motive power from electric wires fitted to the house for electric lighting or
other purposes.
The pump, preferably of the rotary type, is geared in a suitable manner with an
electro-motor and both are attached to a portable cistern containing a supply of
water. A quantity of electric wire can be carried on a revolving reel attached to-
the cistern so that connection may be made to switches on the permanent wires at
fixed points and the pump may be transported to the scene of operations.
If preferred a quantity of hose may be carried on the cistern and the pump
connected close to the permanent switches and the hose run out as far as may be
desired.
A switch may be attached to the motor for controlling it when at a distance from
the main switches.
In the event of the electro-motor failing to act I arrange the pump so that it can.
be operated effectually by hand.

Improvements in Portable Electrically Driven Pumps.
I, JAMES COMPTON MERRYWEATHER, of Greenwich Road, Greenwich, 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 :-
The object of my invention is to construct a small domestic pumping engine for-
fire extinguishing, or other purposes, driven by an electro motor which can take its
motive power from electric wires fitted to the house for electric lighting or other
purposes.
The pump, preferably of the rotary type, is geared in a suitable manner with an
electro motor and both are attached to a portable cistern containing a supply of
water. A quantity of electric wire can be carried on a revolving reel attached to
the cistern, so that connection may be made to switches on the permanent wires at
fixed points and the pump may be transported to the scene of operations.
If preferred a quantity of hose may be carried on the cistern and the pump-
connected close to the permanent switches, the hose being carried out as far as may
be desired.

page_text: A switch may be attached to the pump for controlling it when at a distance
from the main switches.
In the event of the electro motor failing to act I arrange the pump so that it can
be operated effectually by hand.
In the accompanying drawing,-A is the pump, B is the motor, C & D are the
toothed wheels for gearing them together; if desired they can be connected by
worm wheel gearing. E is the cistern from which the pump A takes its supply,
mounted on wheels F, & G are the handles for wheeling the same. K is the
delivery hose. L is the reel for carrying the electric wire. M & N is the wall
plug for connecting the wire to the electric main O. P is the permanent switch.
In the event of the electro motor failing to act, the toothed wheel C is thrown
ont of gear and a winch handle attached to the wheel D to enable the pump to be
worked by hand.
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 ;-
1. The combination of a pump driven by an electro motor, with a portable
cistern containing water for fire extinguishing purposes.
