PROVISIONAL SPECIFICATION.
An Improved Method of and Means for Increasing the Efficiency of
Dynamo-electric Generators.
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:-
A. M. Perkins Patent dated 16th December 1839 No. 8311 for "Apparatus for
transmitting heat by circulating water" proved that great heat can be transmitted
by the circulation of water in closed pipes conuected with a furnace.
In my present invention I adopt the processes described in Perkin's Specification
which states that a number of small tubes are employed heated by a furnace and
connected with a number of similar closed tubes the water in which continually
circulates caused by the heat of the furnace a very high temperature being produced
in the water of the last named series of tubes contained in an iron vessel which
may be about 10 feet long (more or less) and placed in a horizontal position a
number of copper tubes of the same length being previously introduced which are
open at both ends for the passage of the electric air which rushes into them with
great force and passing into a receptacle where the air is utilized by brass pointed
wires.
Enormous quantities of steam are constantly wasted for want of proper
appliances to utilize it which however can be accomplished by the following
arrangement The pipe from which the steam escapes should be made about
eight feet longer and enclosed in a copper tube of a size, to leave a vacant space
between the two pipes which the steam in the inner one would heat sufficiently to
cause a rush of air into the said space. The steam and air will thus travel side by
side to the place of issue and be there intermixed and passed into a room or other
receptacle for conversion into electricity (for lighting or other purposes) by
impinging on sharp points or edges of brass or other suitable metal.
Or my improvements can be advantageously employed by using a dynamo in
producing, the air from the tubes being greatly improved by the addition of fresh
currents of electricity and heat which are inseparable from it.
Also by the introduction of plain water salt and water or chemical solutions by
means of asbestos cords saturated therewith in a trough which by capillary
attraction supply a regulated quantity of the solution and by the extreme heat
pervading the copper tubes or openings convert the water into steam which is
always charged with electricity.
" should
With the above addition to the ordinary atmosphere a "dynamo
produce a much better result than when it only possesses the normal electricity of
the air.
Should the copper tubes be found indispensable iron or steel tubes can be first
coated on their outsides with a coat of varnish and same dried by heat and by
keeping their insides clean and then immersing them in a tank containing a solution
of copper combined with a galvanic battery a sufficient coating of copper can be
deposited on the inside surfaces of the tubes.
The tubes and open spaces should be smaller at the point of issue and be closed
thereat for a short time prior to being put in action as they might otherwise admit
air at both ends of the hot tubes.
Alternate portions of copper and zinc (perforated) placed in the open spaces with
asbestos cords might generate galvanic currents.
When the air has by the above process been enriched with electricity it is con-
ducted into a chamber containing a "dynamo" or "dynamos" and the result of its

page_text: action would greatly its action upon atmospheric air the electricity in which is of
exceeding tenuity.
One arrangement of apparatus for carrying my invention into practice is as
follows although I do not limit thereto as the same may be considerably varied
without departing from the true character of my invention.
For this purpose I find it advantageous to employ a strong iron vessel about
10 feet long (more or less) and placed horizontally to contain water wherein a series
of small iron tubes filled with water are placed at the bottom and connected with
a spiral of similar tubes placed in a furnace these tubes being also filled with water.
These two sets of tubes being connected together will maintain a constant circu-
lation of the water caused by the heat of the furnace. The circulation of the
water in the small tubes imparts great heat to the tubes in the iron vessel which in
turn heats all the other parts of the apparatus.
Or I arrange a series of copper tubes which pass through both ends of the iron
vessel which soon heat the copper tubes instantly drawing the air with great
velocity passing through the entire length of the iron vessel in contact with the
copper lining of the outer spaces where it would also be in contact with the copper
lining of the openings or copper tubes and with slips of thin sheet copper perforated
with holes which present great numbers of sharp points to produce electricity-
that and heat being inseparable.
By introducing asbestos cords into the open spaces of the vessel when charged
with water or any suitable solution in a trough to saturate any of them will by
capillary attraction supply a regulated quantity of them whereby the water in
them will be converted into steam which is known to be charged with electricity.
Various means for producing heat for the above described purposes may be
employed which may be found most advantageous. -
Some portions of the apparatus employed in my invention may need to be
insulated from the earth in which case it is important that such insulation should
be carefully attended to.

An Improved Method of and Means for Increasing the Efficiency of
Dynamo-electric Generators!
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 :-
My present invention relates to obtaining electricity and the essential feature of
my present invention consists in a special method and means of increasing the
volume of electricity obtainable from a dynamo.
For this purpose I proceed as follows reference being had to the accompanying
sheet of drawings
Figure 1 of which is a diagram or outline of suitable apparatus for producing' the
improvements according to my present invention and
Figure 2 is a plan of Figure 1.
a is a steam generator or boiler of any suitable form and dimensions from which
a number of steam pipes bare led to a cylindrical or other case c which case may or
may not have a bell mouth such as d.
The upper end of this chamber formed by the case or wall is open and the
upper ends of the steam pipes bare also open so that the air entering the case cat

page_text: the bottom d thereof will become highly heated by contact with the steam pipes 6
(which are advantageously copper) and the heated air and steam which mingle and
issue together at the top of the chamber c is conducted by a suitable pipe or other
conduit and released near the dynamo and caused to flow around the dynamo (or
dynamos) and such highly heated air and steam being heavily charged with
electricity will thus cause the dynamo to produce an increased quantity of
electricity.
If desired the steam pipes & may be closed at the upper part a so as to merely
form circulating pipes highly heated by steam or it may be by hot water so that the
air entering the chamber e will be highly heated as before and thereby become
heavily charged with electricity such highly heated air being conducted to the
dynamo and having similar advantageous action as when mingled with steam as
above described.
Other matters referred to in my Provisional Specification herein I have either
abandoned or modified and embodied in separate applications for Patents.
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 1
claim is :-
The improved method of assisting the productiveness or increasing the volume
of electricity obtained from a dynamo by currents of heated air alone or air and
steam combined substantially in the manner and for the purposes hereinbefore set
forth and described.
