TO ALL TO WHOM THESE PRESENTS SHALL COME, I, CHARLES

WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fourth day of November, in the year of our Lord
One thousand eight hundred and sixty-seven, in the thirty-first year of Her
reign, did for Herself, Her heirs and successors, give and grant unto me, the
said Charles. Riley, Her special licence that I, the said Charles Riley,
my executors, administrators, and assigns, or such others as I, the said
Charles Riley, my executors, 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 "IMPROVE-
MENTS IN TUBULAR BOILERS," upon the condition (amongst others) that I, the
said Charles Riley, 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 Charles Riley, do hereby declare the
nature of my said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:
This Invention relates to tubular or multitubular boilers, and the improve-
ments have for their object, first, to protect the heating surfaces of the boiler
plate or plates around the fire-box, more particularly those plates in which
the ends of the tubes nearest to the fire are fixed, and also the ends of the
said 'tubes' themselves, from 'the direct action or contact of the fire or flame
from the fire-box, and thus prevent the boiler plate and tubes from being
burnt or rapidly destroyed thereby; secondly, to economise the consumption
امراه
of fuel.

::
In carrying out the said improvements in practice, I fix or place a per-
forated plate or plates, a grate or grates, bars, or other equivalents, in metal,

page_text: fire-bricks or lumps, or other suitable material in the fire-box or in or before
the flue or tubes and between the burning fuel and the boiler plate or plates
and flue or tubes before mentioned.
I claim the placing or fixing of a perforated plate, grate bars, or other
form of fire-protector, between the burning fuel and the heating surfaces of
boilers.
In witness whereof, I, the said Charles Riley, have hereunto set my
hand and seal, this Thirtieth day of April, in the year of our Lord
One thousand eight hundred and sixty-eight.
CHARLES RILEY. (L.S.)
