Year: 1869

page_text: LETTERS PATENT to Henry Ormson, of Chelsea, in the County of
Middlesex, Horticultural Builder and Hot Water Apparatus Manu-
facturer, for the Invention of "IMPROVEMENTS IN BOILERS FOR HOT
ADD ANDRADATED AND CAN RETRATING PURDORES "
Scaled the 10th September 1869 and dated the 11th March 1869.
PROVISIONAL SPECIFICATION left by the said Henry Ormson at the
Office of the Commissioners of Patents, with his Petition, on the
11th March 1869.
I, HENRY ORMSON, of Chelsea, in the County of Middlesex, Horti-
cultural Builder and Hot Water Apparatus Manufacturer, do hereby
declare the nature of the said Invention for "IMPROVEMENTS IN BOILERS
POR HOT WATER APPARATUS AND STEAM GENERATING PURPOSES," to be as
follows:-
This Invention has reference to certain arrangements for adding
largely to the heating surface of boilers for hot water apparatus and
steam generating purposes, and at the same time economizing the fuel.
These arrangements consist in forming the boiler in two or more parts
connected together by suitable tubes, ducts, or passages. One of these

page_text: parts is the outer or main portion which has its heating surface con-
structed in the manner of convolutions or of projections so as to fully
expose such surface to the action of the fire when the furnace is
enclosed in such main part, or to the action of the fire or heat as the
case may be when the fire is not so enclosed. The other part or parts
of the boiler consist of one or more chambers or water or liquid
receptacles which I make to correspond in form and construction to
the form of the interior surface of the boiler, such chamber or chambers,
receptacle or receptacles, being when not formed so as to be a con-
tinuation of the main part with tubes, ducts, or passages connecting
the parts together and allowing of the circulation of the fluid therein.
By these arrangements it is intended to provide that the full effect of
the heat may be obtained from the fuel before the same escapes by
the chimney or smoke duct. These boilers may be made of welded
wrought iron, rivetted wrought iron, or cast iron, but I prefer the
former.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Henry Ormison in the Great Seal Patent Office
on the 10th September 1869.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HENRY
ORMSON, of Chelsea, in the County of Middlesex, Horticultural Builder
and Hot Water Apparatus Manufacturer, send greeting.
WHEREAS IIer most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Eleventh day of March, in the year of
our Lord One thousand eight hundred and sixty-nine, in the thirty-
second year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Henry Ormson, Iler special licence
that I, the said Henry Ormson, my executors, administrators, and
assigns, or such others as I, the said Henry Ormson, 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 "IMPROVEMENTS IN BOILEES
FOR HOT WATER APPARATUS AND STEAM GENERATING PURPOSES," upon the

page_text: performed or put in practice, I would remark that variations may be
made in some of the details before described; but what I claim is, the
general arrangements and combination of the flues and different parts
as shown and described for the greater economy of fuel and the more
rapid generation of steam and heating of hot water.
In witness whereof, I, the said Henry Ormson, have hereunto set
my hand and scal, this Ninth day of September in the year
of our Lord One thousand eight hundred and sixty-nine.
Witness,
HENRY HOWLETT.
HENRY ORMSON. (L.S.)
