IMPROVEMENTS IN OBTAINING STEAM POWER, AND IN REGU- CAMB
Year: 1853

page_text: LETTERS PATENT to Frederick Lipscombe, of 233, Strand, in the
County of Middlesex, Water Filter Manufacturer, for the Inven-
tion of "IMPROVEMENTS IN OBTAINING STEAM POWER, AND IN REGU-
CAMB
Sealed the 21st April 1854, and dated the 2nd November 1853.
PROVISIONAL SPECIFICATION left by the said. Frederick Lips-
combe at the Office of the Commissioners of Patents, with his
Petition, on the 2nd November 1853..
I, FREDERICK LIPSCOMBE, of 233, Strand, in the County of Mid-
dlesex, Water Filter Manufacturer, do hereby declare the nature of the
said Invention for "IMPROVEMENTS IN OBTAINING STEAM POWER, AND IN
REGULATING THE SAME," to be as follows:-
I place a clack or other self-acting valve or self-acting valves, formed
of metal or other suitable material or combination of materials, at the
entrance of or inside the channel or channels that convey steam from
the boiler or other vessel used for generating steam into the cylinder
of an engine or other point where the effective force of the steam is to
be used, which valve or valves open only one way. I superheat any

page_text: portion of the steam channel or channels between the self-acting valve
or valves and the cylinder or other point where the effective force of
the steam is to be used, either by flame or heat from combustible
material acting directly against it; or I place any portion of the channel
or channels against or near the boiler furnace where the temperature is
higher than the steam in the boiler or other vessel used for generating
steam; or I thicken any portion of the steam channel or channels, and
carry a metallic elongation therefrom into the boiler furnace, in order
that heat may be transmitted to the steam channel or channels; or I
heat the whole or any portion of the steam channel or channels by any
other convenient means. By either of these arrangements the steam
when it first gets in contact with the heated portion of the steam
channel or channels expands, the valve thereafter opens only to allow
steam to pass through when the pressure against it is unbalanced, thus
entirely, or nearly so, preventing heat from the superheated portion
of the steam channel or channels gaining access into the boiler or other
vessel used for generating steam, and causing an explosion by raising
excessively the temperature there.
The general objects of this Invention are the superheating the whole or
any portion of the channel or channels that convey steam from the boiler
or other vessel used for generating steam to the cylinder or cylinders of
an engine or other point where the effective force of the steam is to be
used, in combination with a self-acting valve or self-acting valves, such
valve or valves being intended to prevent heat from the superheated
channel or channels gaining access into the boiler or other vessel used
for generating steam; and the placing a self-acting valve or self-acting
valves inside or outside the channel or channels that convey steam from
the boiler or other vessel used for generating steam, such valve or valves
being intended to prevent heat from the superheated channel or chan-
nels gaining access into the boiler or other vessel used for generating
steam.

Water Filter Manufacturer, send greeting.

WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Second day of November, in the of
our Lord One thousand eight hundred and fifty-three, in the seventeenth
year of Her reign, did, for Herself, Her heirs and successors, give and
grant unto me, the said Frederick Lipscombe, Her special license that
I, the said Frederick Lipscombe, my executors, administrators, and
assigns, or such others as I, the said Frederick Lipscombe, my execu
tors, administrators, or 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 "IMPROVEMENTS
IN OBTAINING STEAM POWER, AND IN REGULATING THE SAME," upon the
condition (amongst others) that T, the said Frederick Lipscombe, by an
instrument in writing under my hand and seal, 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 Frederick Lipscombe, do hereby
declare the nature of my said Invention, and in what manner the
is to be performed, to be particularly described and ascertained in
and by the following statement:
My said Invention relates to the causing steam generated in steam
boilers to pass through one or more self-acting valves, and then to
become surcharged or superheated previous to entering the cylinder of
an.engine, and consists in placing a clack or other self-acting valve or
self-acting valves, formed of metal or other suitable material or com-

page_text: bination of materials, at the entrance of or in any part of the interior of
the steam pipe or passages that convey the steam from the boiler or
other vessel used for generating steam into the cylinder of an engine
or other point where the effective force of the steam is to be used,
which valve or valves open only one way. I superheat the whole or any
portion of the steam pipe or passages between the self-acting valve or
valves and the cylinder or other point where the effective force of the
steam is to be used, either by flame or heat from combustible material
acting directly against it; or I place any portion of the steam pipe or
passages against, in, or near the boiler furnace, where the temperature
is higher than the temperature of the steam in the boiler or other
vessel used for generating steam; or I thicken any portion of the steam
pipe or passages, and carry a metallic elongation therefrom into the
boiler furnace, in order that heat may be transmitted to the steam pipe
or pipes; or I heat the whole or any portion of the steam pipe or pipes
by any other convenient means. By either of these arrangements im-
mediately the steam boiler regulator is opened the steam from the boiler
opens and passes through the self-acting valve or valves, comes in con-
tact with the heated portion of the steam pipe, and in consequence has
its temperature raised, thereby causing it to expand. The self-acting
valve or valves then regulate the supply of boiler steam to the super-
heated portion of the steam pipe by opening only to allow the steam to
pass through to the superheated portion of the steam pipe or pipes,
when the superheated steam pressure against one side of such valve or
valves is less than is exerted by the boiler steam pressure against the
other side, thus entirely, or nearly so, preventing heat from the super-
heated portion of the steam pipe from gaining access into the boiler or
other vessel used for generating steam, and causing an explosion by
raising excessively the temperature therein. Directly the steam boiler
regulator is closed of course no more steam can get to the superheated
portion of the steam pipe or-passages until it is again opened.
Having now described and particularly ascertained the nature of my
said Invention, and the manner in which the same is or may be used
or carried into effect, I would observe, in conclusion; that I do not
confine or restrict myself to the precise details or arrangements which a

page_text: I have had occasion to describe or refer to, as many variations may
be made therefrom without deviating from the principles or main
features of my said Invention; but what I consider to be novel and
original, and therefore claim as the Invention secured to me by the
herein-before in part recited Letters Patent, is,-
The system or mode of superheating the whole or any portion of the
steam pipes or passages which convey the steam from the boiler or
generator to the cylinder of an engine or other point where the effective
force of the steam is to be used, such pipe or passages having one
or more self-acting valves, either inside or at their entrance, for the
purpose of preventing the heat from the superheated pipe or pas-
sages from gaining access into the boiler or generator, as herein-before
described.
In witness whereof, I, the said Frederick Lipscombe, have here-
unto set my hand and seal, the First day of May, One
thousand eight hundred and fifty-four.
FRED LIPSCOMBE. (L.S.)
