Improvements in Obtaining Electricity for Electric Lighting Motive
Power and other like 'Purposes.
I WILLIAM BOGGETT of 97 Cheyne Walk Chelsea in the County of Middlesex
Gentleman do hereby declare the nature of this invention to be as follows:-
In May 1887 I invented and published a description of an apparatus which
demonstrated the fact that the amount of electricity in water entirely depends upon
the degree of beat it contains which knowledge is the foundation of my present
invention and has led me to adopt an old process which is described in Perkin's
Patents (about the year 1843) for obtaining heat by means of water contained in
closed pipes connected with a furnace.
A like process is also available for injecting dry or super-heated steam .into closed
pipes with the same object. In these cases according to my present invention' coils of
insulated copper wire are applied to collect and transimit the electricity of the intensely
heated water or steam in the said pipes.
My invention also embraces the employment of galvanic batteries in furtherance of
the aforesaid purpose for which I find it most advantageous to employ those known
as bichromate batteries into the solutions of which great heat and a prodigious
increase of electric force is obtained even in cells of small size but an important
feature of my improvements consists in largely increasing the size (and in some
instances the number of the cells) in order to generate and utilize sufficient power to
maintain an extensive supply for lighting by electricity motive power and other like
purposes.
The substitution of salt water for fresh in making battery solutions and of pumping
hot in place of cold air into them also forms parts of my present invention.
The desired effect can be economically attained in the following manner vi. :-
By the use of galvanic solutions consisting of salt water kept in a heated state by
pumping hot or cold air into them.
Or by dilute sulphuric acid and pumping air into them.

Improvements in Obtaining Electricity for Electric Lighting Motive
Power and other like Purposes.
I WILLIAM BOGGETT of 97 Cheyne Walk Chelsea in the County of Middlesex
Gentleman 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 :-
In May 1887 I invented and published a description of an apparatus which
demonstrated the fact that the amount of electricity in water entirely depends upon
the degree of heat it contains which knowledge is the foundation of my present
invention and has led me to adopt an old process such as that described in
Perkins Patent (No 8311 of 1839) for obtaining heat by means of water contained in
closed pipes connected with a furnace.
The main portion of the said pipes a reference being had to the accompanying sheet
of drawings are enclosed in a boiler b containing salt or fresh water the water in all
the closed pipes a'circulating by means of the heat derived from the furnace c imparts

page_text: electricity to the water in the boiler in proportion to the heat it receives-the
said electricity being transmitted to the desired locality by means of copper
conductors d d.
•
The entire apparatus (boiler furnace pipes etcetera) such as that shown for the sake
of example only must be properly insulated from the earth in any suitable manner and
the boiler may also be coated with mineral wool to prevent the escape of heat as far
as possible.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I would remark that I am
aware that electricity has been obtained direct from steam as in the well-known
manner exhibited at the Polytechnic Institution in London many years ago and I
therefore make no claim thereto whatever but what I do claim as novel and as my
invention is :-
1. Obtaining electricity direct from water contained in closed pipes parts of which
are placed in a suitable furnace to heat the water substantially in the manner and for
the purposes herein before described.
2. The production of electricity substantially in the manner and for the purposes
hereinbefore described.
Dated this 4th day of May 1889.
