PROVISIONAL SPECIFICATION.
Improvements in or connected with Fire-alarm Gongs.
We, HENRY LIVESEY, of Greenbank Iron Works, Blackburn, in the County
of Lancaster, Machinist, and THOMAS GILL, of Greenbank Iron Works, aforesaid,
Manager, do hereby declare the nature of this invention to be as follows:-
This invention relates to that class of alarm apparatus in which a gong is sounded
by a hammer caused to rotate by a small turbine or water motor as water flows
through the pipes, and is designed with the object of transmitting the alarm to
another apparatus or alarm signal placed at a distance, such as an office, fire station,
or the like.
To the spindle of the hammer or to other moving or rotating part of the alarm
signal apparatus, we attach or connect an appliance which on any motion taking
place to sound the gong, will generate an electric current or complete an electric
circuit and so set in action an alarm bell or other instrument placed at a distance
therefrom. This may be effected by means of a small dynamo geared to or driven
from the hammer spindle by means of wheels or pulleys. Or it may be effected by
means of a switch or other contact making device which will be moved on any
motion taking place in the alarm apparatus and an electric circuit closed or
completed, which will bring into action an electric bell or other alarm signal.
Communication between one alarm signal and another may be through existing
telephone or other wires or special wires may be erected for the purpose.
By this arrangement as soon as an alarm of fire is sounded on the gong in the
usual way outside the factory, the same is at once transmitted therefrom to one, two,
or more alarms situated in the office, fire station or other desired station.

COMPLETE SPECIFICATION.
Improvements in or connected with Fire-alarm Gongs.
We, HENRY LIVESEY, of Greenbank Iron Works, Blackburn, in the County
of Lancaster, Machinist, and THOMAS GILL, of Greenbank Iron Works, aforesaid,
Manager, 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 :-
This invention relates to that class of fire-alarm apparatus in which a gong is
sounded by a rotating hammer actuated by a small turbine or water motor as a
current of water flows through the pipes, and is designed with the object of
transmitting the alarm to another apparatus or alarm signal placed at a distance
such as in an office, at a fire station, or the like.
It consists essentially of the combination with the alarm apparatus of a small
electric generator or switch whereby on the alarm being sounded or any movement
of the apparatus taking place an electric current is transmitted to another station
to actuate another alarm such as an electric bell or other signal.
The invention will be fully described with reference to the annexed drawing
in which as an example a small electric generator is shown connected to the fire-
alarm apparatus.
Fig. 1 front elevation

page_text: The alarm apparatus comprises the gong A the hammer 13 and the turbine C by
which the hammer is rotated the turbine being actuated by a current of water
flowing through the pipes all of which are constructed in the usual way to sound an
alarm in case of fire.
On the shaft which carries the hammer B, rotated by the turbine C we fix a
grooved pulley D preferably placed behind the alarm apparatus. By the pulley D
we connect by means of the strap or cord d a small electric generator E which on.
any motion taking place in the parts of the apparatus to sound the gong is at once
set in motion and will generate a current of electricity.
The current so generated is utilized for the purpose of ringing one two or more
bells or alarms at a distance so that the alarm given at the seat of the fire will at
once be communicated to any required station.
It is obvious that the electric generator E may be geared with the hammer and
turbine shaft by wheels or other gearing instead of the strap or cord d. Or instead
of the generator E a permanent generator or battery may be employed connected
to the alarm gong by means of a switch or other contact making device which will
be moved to make contact or close a circuit on any movement of the alarm
apparatus taking place and so bring into action an electric bell or other alarm
signal at any distant place.
Communication between one alarm signal and another may be through existing
telephone or other wires or special wires may be erected for the purpose or by a
simple contrivance may be connected to a subscribers exchange telephone instrument
so as to automatically alarm the central office-and so the fire station-at the
outbreak of a fire.
By this arrangement as soon as an alarm of fire is sounded on the gong in the
usual way outside the factory, the same is at once transmitted therefrom to one, two,
or more alarms situated in the office, fire station or other desired station. This
immediate and automatic alarm will be found of the very greatest utility inasmuch
as it is given within three seconds from the starting of the sprinkler bell, and thus
the most valuable time--that of the few minutes following an outbreak-is
economised.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is
The combination with a fire-alarm gong or apparatus, of an electric generator
or switch which is operated by the actuating mechanism of the alarm apparatus
whereby on any movement taking place in the apparatus to sound an alarm an
electric current is at once generated or transmitted to a distant station to actuate
an electric bell or other alarm signal substantially as described.
