page_text: LETTERS PATENT to Henry Alfred Jowett, of Sawley, in the County of
Derby, Civil Engineer, for the Invention of "IMPROVEMENTS IN OBTAINING
MOTIVE POWER, AND IN TRANSMITTING THE SAME FROM PLACE TO PLACE, AND
IN APPARATUS CONNECTED THEREWITH."
Sealed the 21st January 1868, and dated the 25th July 1862.
PROVISIONAL SPECIFICATION left by the said Henry Alfred Jowett at
the Office of the Commissioners of Patents, with his Petition, on the
25th July 1862.
I, HENRY ALFRED JOWETT, of Sawley, in the County of Derby, Civil
Engincer, do hereby declare the nature of the said Invention for "IMPROVE
MENTS IN OBTAINING MOTIVE POWER, AND IN TRANSMITTING THE SAME FROM
PLACE TO PLACE, AND IN APPARATUS CONNECTED THEREWITH," to be as follows:-
I propose to obtain compressed air as a motive power for transmission by
means of pumps for that purpose worked by steam engines, and by pipes or
tubes connected therewith to collect the same into reservoirs or receivers.
I propose, also, to obtain compressed air as a motive power for transmission
by means of a fall of water in tidal rivers or reservoirs of water having a
natural or artificial fall of water to set in motion the requisite machinery, that
is to say, water wheels, turbines, Barker's mill, or hydraulic ram for working
pumps to condense or compress air, and through pipes or tubes to collect it
into reservoirs or receivers, and to transmit such air from one place to
another where motive power is required by one or more main pipes or tubes
placed under streets or highways, or otherwise connected with the central

page_text: reservoir, or one of the branch reservoirs, in like manner as is adopted by gas
and waterworks establishments.
I propose that the reservoirs or receivers and main pipes or tubes, and
branch or connecting pipes or tubes shall, by means before suggested, have
compressed air constantly supplied and be kept up to any given pressure accord-
ing to the consumption of air required, and by opening stop-cocks on such
pipes or tubes, be supplied to the engines of the various warehouses, shops,
factories, docks, hoists, cranes, powder magazines, or any other place or places
whero power is required.
And. I proposo to place in the main pipes or tubes conducting the com-
pressed air from the reservoirs or receivers slide valves at certain distances,
say, for example, every hundred yards, in order to test the security or air-
tightness of the pipes, without tho necessity of opening the ground the
whole distance to ascertain where any damage may have occurred to cause
leakage.
I propose to attach to the shaft of the fly wheel of every description of
motive power engine a pinion connected with the cylinder working in gear
with a toothed wheel of a larger size to decrease the speed. On the opposite
side of such larger wheel I introduce a second pinion working in gear with a
second wheel, of such size as shall enable me to register for observation by an
index similar to the steam or gas index in common use the revolution of the
shaft or fly wheel or spindle, and thereby (the contents of the cylinder
previous to such revolutions being known by its size) to ascertain the precise
amount of air which has been supplied from it.
I claim this Invention in its entirety and the several parts of it as appli-
cable thereto, and I particularly claim the mechanical meter, above described.
I make no claim to the principle of compressed air acting as a motive
power, or to its transmissibility..
I do not rigidly confine myself to the precise methods, herein described, for
compressing air & for transmitting the same.

page_text: WHEREAS Her most Excellent Majesty Queen Victoria, by. Her Letters
Patent, bearing date the Twenty-fifth day of July, in the year of our Lord
One thousand eight hundred and sixty-two, in the twenty-sixth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Henry Alfred Jowett, Her special licence, that I, the said Henry
Alfred Jowett, my executors, administrators, and assigns, or such others as
I, the said Henry Alfred Jowett, my executors, administrators, and assigns,
should at any time agree with, and no others, from time to time and at all
times thereafter during the term therein expressed, should and lawfully might
make, use, exercise and vend, within the United Kingdom of Great Britain
and Ireland, the Channel Islands, and Isle of Man, an. Invention for "In-
PROVEMENTS IN OBTAINING MOTIVE POWER, AND IN TRANSMITTING THE SAME FROM
PLACE TO PLACE, AND IN APPARATUS CONNECTED THEREWITH," upon the condition
(amongst others) that I, the said Henry Alfred Jowett, my executors or
administrators, by an instrument in writing under my, or their, or one of
their hands and seals, should particularly describe and ascertain the nature
of the said Invention, and in what manner the same was to be performed,
and cause the same to be filed in the Great Seal Patent Office within six
calendar months next and immediately after the date of the said Letters
Patent.
NOW KNOW YE, that I, the said Henry Alfred Jowett, do hereby
declare the nature of my said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:-
I propose to obtain compressed air as a motive power for transmission by
ineaus of pumps for that purpose worked by steam engines, and by pipes or
tubes connected therewith to collect the same into reservoirs or receivers.
The reservoirs or receivers will be supplied with air guages for the purposo
of: always ascertaining the precise pressure thereon, and regulating the same.
There will also be safety valves on cach reservoir or receiver-in. the manner
used for the ordinary steam engine boilers.
I propose, also, to obtain compressed air as a motive power for transmission
by means of a fall of water in tidal rivers or reservoirs of. water having a
natural or artificial fall of water to set in motion the requisite machinery, that
is to say, water wheels, turbines, Barker's mill, or hydraulic ram for working
pumps to condense or compress air, and through pipes or tubes to collect it.
into reservoirs or receivers, and to transmit such air from one place to another
where. motive power. is required by one or more main pipes or tubes placed
under streets or highways, or otherwise connected with the central reservoir>

page_text: or one of the .branch reservoirs,. in. like manner as is adopted by gas and
waterworks establishments.
:
I propose that the reservoirs or receivers and main pipes or tubes, and
branch or connecting. pipes or tubes shall, by means before suggested, have
compressed air constantly supplied and be kept up to any given pressure,
according to the consumption of air required, and by opening stop-cocks or
other valves in such pipes or tubes be supplied by connecting pipes or tubes
to the engines of the various warehouses, shops, factories, docks, hoists, cranes,
powder magazines, or any other places or places where power is required. . .
And, particularly, I propose that in the main pipes containing compressed
air outlets with screwed plugs should be placed at certain distances, and
more especially one precisely opposite to each opening where water plugs are
placed in streets or roads, in order that a small portable air engine might be
attached on the end of the pumping engine, and by simply unscrewing the air
plug, and connecting it by a short pipe or hose with the air engine, it could
be set into instantaneous motion for pumping water for extinguishing fires.
And I also propose these outlets with screwed plugs to be made available
for contractors for buildings and other public works, so that the power may be
applied, as before suggested, to portable engines on the spot for excavating,
pumping, draining, raising stone or other building materials, sawing wood or
stone, and-other works where motive power is required.
And I propose to place in the main pipes or tubes conducting the com-
pressed air from the reservoirs or receivers slide valves at certain distances,
say, for example, every one hundred yards, in order to test the security or air-
tightness of the pipes without the necessity of opening the ground the whole
distance to ascertain where any damage may have occurred to cause leakage,
for example, by closing number 1 valve at one hundred yards from the plant
or establishment, and screwing on there an air guage on the side nearest the
plant. If the one hundred yards of pipe is sound the air guage will stand
at one pressure, and by opening the valve the remainder of the valves
may be used, and thus the whole length of the pipe be tested in like
manner.
.
I propose to attach to the shaft of the fly wheel of every description of
motive-power engine a pinion connected with the cylinder working in gear
with a toothed wheel of a larger size to decrease the speed. On the opposite
side of such larger wheel I introduce a second pinion working in gear with a
second wheel of such size as shall enable me to register for observation by an
index similar to the steam or gas index now in common use, the revolutions
of the shaft or fly wheel or spindle, and thereby (the contents of the cylinder

page_text: previous to such revolutions being known by its size) to ascertain the precise
amount of air which has been supplied from it.
I claim this Invention in its entirety, and the several parts of it as appli-
cable thereto, and I particularly claim the application of tidal rivers and fall
of water as a motive power, and the mechanical meter, above described.
I make no claim to the principle of compressed air acting as a motive
power, or to its transmissibility.
I do not rigidly confine myself to the precise methods herein described.
In witness whereof, I, the said Henry Alfred Jowett, have hereunto set
my hand and seal, this Twenty-third day of January, in the
year of
our Lord One thousand eight hundred and sixty-three.
