Improved Apparatus for Automatically Starting Electric Fire
Pumps and other Electrical Machinery.
I, THOMAS RUNGAY, of Blenheim Palace, Woodstook, in the County of
Oxfordshire, Electrical Engineer, do hereby declaro the nature of this invention to
be as follows:-
My invention relates to an improved apparatus for automatically starting olectric
fire pumps and other electrical machinery.
The mode of operation is by a switch held in position by a soft iron weight
attached to one end of a chain which passes round a wheel on arm of switch, there
being a heavier weight on other end of chain heavy enough to pull switch over whon
weight is released.
The switch being connected with electric light mains or accumulators the weight
is held down by a pivotted lever in circuit with an electro magnet when a current
of electricity is sent round the coil of electro magnet the core of electro magnet is
magnetized, which attracts the soft iron weight and releases same.
On being released the heavier weight pulls the switch over, starting the motor
through resistance.
The electro magnet can be excited by a current of clectricity flowing, the circuit
being closed through a thermometer when the temperature rises to any given degree
being in circuit with a battery of celle, thereby operating the motor automatically,
attached to which are the fire pumps or other machinery. The circuit of electro
magnet can also be closed by presses thereby operating motor. There can also bo
attached to the motor the necessary apparatus for calling the fireman.
This apparatus can also be used for switching on and off electric light at any
given time by being connected with clockwork. When weight is attracted thero is n
spring at the other end of pivotted lever which broaks the electro magnet circuit.

Improved Apparatus for Automatically Starting Electric Fire
Pumps and other Electrical Machinery.
I, THOMAS RUNGAY, of Blenheim Palace, Woodstock, in the County of
Oxfordshire, Electrical 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 relates to an improved apparatus for automatically starting electric
fira numus and other electrical machinery.

page_text: According to the accompanying drawing the mode of operation is by a switch a
held in position by a soft iron weight attached to one end of a chain d which
passes round a wheel in on arm of awitch, there being a heavier weight e on other
end of chain, heavy enough to pull the switch a over when weight b is released.
The switch a being connected with electric light mains or accumulators e the
weight bis held down by a pivoted lover fin circuit with an electro magnet 9:
when a current of electricity is sent round the coil of electro magnet g the core of
electro magnet is magnetized, which attracts the soft iron weight band releases
Bame.
On being released the heavier weight e pulls the switch over, starting the motor h
through resistance i.
The electro magnet g can be excited by a curront of electricity flowing, the
circuit being closed through a thermometer j when the temperature rises to any
given degree being in circuit with a battery of colla, thereby operating the
motor automatically; attached to which are the fire pumps or other machinery.
The circuit of electro magnet can also be closed by a press or presses thereby
operating the motor h. There can also be attached to the motor h the necessary
apparatus for calling the fireman.
This apparatus can also be used for switching on and off electric light at any
given time by being connected with clock-work. When weight bis attracted there
is a spring at the other end of pivoted lever which breaks the electro magnet
circuit.
The battery of cells & are supported on the board or frame n by a bracket.
Various parts of the apparatus are mounted on a board or in a frame of any size
with suitable fittings or fastenings for building up the apparatus above described.
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 apparatus for automatically starting electric fire pumps and other
electrical machinery, the combination of the various parts fully above described in
this specification for the purpose specified.
2. In an apparatus for automatically starting electric fire pumps and other
electrical machinery, the combination of the switch a weight 6 heavy weight o
chain d accumulators e pivoted lever spring electro magnet g motor h resistance i
thermometer battery of cells press wheel m board or frame n and bracket o or
their equivalents, substantially as herein described and according to the accom-
panying drawing.
