IMPROVEMENTS RELATING TO THE EMPLOYMENT OF AERATED WATER FOR THE PRODUCTION OF STEAM IN LOCOMOTIVE AND OTHER BOILERS
Year: 1875

page_text: LETTERS PATENT to Tom Hurry Riches, of Cardiff, in the County of
Glamorgan, Engineer, for the Invention of "IMPROVEMENTS RELATING
TO THE EMPLOYMENT OF AERATED WATER FOR THE PRODUCTION OF STEAM IN
LOCOMOTIVE AND OTHER BOILERS."
Sealed the 18th January 1876, and dated the 28th October 1875.
PROVISIONAL SPECIFICATION left by the said Tom Hurry Riches
at the Office of the Commissioners of Patents, with his Petition,
on the 28th October 1875.
I, TOM HURRY RICHES, of Cardiff, in the County of Glamorgan,
" 'IM-
Engineer, do hereby declare the nature of the said Invention for
PROVEMENTS RELATING TO THE EMPLOYMENT OF AERATED WATER FOR THE PRO-
DUCTION OF STEAM IN LOCOMOTIVE AND OTHER BOILERS," to be as follows:-
My Invention relates to the employment of air combined with water
for the generation or production of steam in steam boilers. The main
object of the said Invention is to economize fuel in the working of loco-
motive and other engines.

page_text: I carry the said Invention into practice in connection with a loco-
motive and similar boilers as follows:-I force atmospheric air into the
feed water in the tank or reservoir for supplying the boiler, and this
combined air and water will then be forced into the boiler by the
ordinary injector force pump or other means. For forcing the air into
the feed water in the tank or other reservoir containing the same,
whether the said reservoir is fixed on the tender or otherwise arranged,
I employ a small injector, constructed similarly or nearly so to those
ordinarily employed for locomotives. The said injector is connected by
a small tube or pipe to the blast pipe of the locomotive, so that I
economize a portion of the exhaust steam for forcing the air into the
feed water; or I may use a fan or rotary pump, operated by one of the
axles of the engine or tender, and connected with the feed water
reservoir; or I may use any suitable apparatus for this purpose.
If desired, instead of forcing the air into the body of water in the
main tank or reservoir, I may arrange a tight or closed vessel or chamber
in connection with the said reservoir, and force the air into the water in
the said closed vessel. The air pipe or tube is provided with a cock or
valve, whereby the quantity of air forced into the water may be regu-
lated as required.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Tom Hurry Riches in the Great Seal Patent
Office on the 27th April 1876.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, TOM
HURRY RICHES, of Cardiff, in the County of Glamorgan, Engineer, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-eighth day of October, in
the year of our Lord One thousand eight hundred and seventy-
five, in the thirty-ninth year of Her reign, did, for Herself, Her
heirs and successors, give and grant unto me, the said Tom Hurry
Riches, Her special licence, that I, the said Tom Hurry Riches, my
executors, administrators, and assigns, or such others as I, the said
Tom Hurry Riches, my executors, administrators, and assigns, should

page_text: 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 RELATING TO THE EMPLOYMENT OF AËRATED
WATER FOR THE PRODUCTION OF STEAM IN LOCOMOTIVE AND OTHER BOILERS," upon
the condition (amongst others) that I, the said Tom Hurry Riches, 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 Offico within six calendar months next and immediately
after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Tom Hurry Riches, 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, reference being had to the accom-
panying Drawing forming a part of this Specification :-
My Invention relates to the employment of air combined with water
for the generation or production of steam in steam boilers. The main
object of the said Invention is to economize fuel in the working of
locomotive and other engines.
I carry the said Invention into practice in connection with a loco-
motive or similar boiler as follows:-1 force atmospheric air into the
feed water in the tank or reservoir for supplying the boiler, and this
combined air and water will then be forced into the boiler by the
ordinary injector, or an injector constructed in the peculiar manner
herein-after described, or by a force pump, or other means. For forcing
the air into the feed water in the tank or other reservoir containing
the same, whether the said reservoir is fixed on the tender or otherwise
arranged, I may employ a small injector constructed similarly or nearly
so to those ordinarily employed for locomotives. The said injector is
connected by a small tube or pipe to the blast pipe when not combined
directly with the boiler of the locomotive, so that I economize a portion
of the exhaust steam for forcing the air into the feed water; or I may
use a force pump or rotary pump operated by one of the axles of the
engine or tender, and connected with the feed water reservoir; or I
may
employ any suitable apparatus for this purpose.

page_text: If desired, instead of forcing the air into the body of the water in the
main tank or reservoir I may arrange a tight or closed vessel or
chamber in connection with the said reservoir, and force the air with the
water in the said closed vessel. The air pipe or tube is provided with a
cock or valve, whereby the quantity of air forced into the water may be
regulated as required.
