CERTAIN IMPROVEMENTS IN STEAM BOILERS
Year: 1852

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME OR BE MADE
KNOWN, I, SAMUEL MORRIS, of Stockport, in the County of Chester, Boiler
Maker, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Royal
Letters Patent under the Great Seal of Great Britain, bearing date at
Westminster, the Third day of June, in the fifteenth year of Her reign, and
in the year of our Lord One thousand eight hundred and fifty-two, did, for
Herself, Her heirs and successors, give and grant unto me, the said Samuel
Morris, my exors, adññiors, and assigns, Her especial license, full power, sole
privilege and authority, that I, the said Samuel Morris, my exors, admors,
and assigns, and such others as I, the said Samuel Morris, my exors, adñors,
or assigns, should at any time agree with, and no others, from time to time
and at all times thereafter during the term of years therein expressed, should
and lawfully might make, use, exercise, and vend, within that part of Her
Majesty's United Kingdom of Great Britain and Ireland called England, Her
Dominion of Wales, the Town of Berwick upon Tweed, and the Islands of
Jersey, Guernsey, Alderney, Sark, and Man, and in all Her Majesty's Colonies
and Plantations abroad, my Invention of "CERTAIN IMPROVEMENTS IN STEAM
BOILERS;" in which said Letters Patent is contained a proviso, that I, the said
Samuel Morris, shall cause a particular description, or instrument in writing
under my hand and seal, of the nature of my said Invention, and in what
manner the same is to be performed or carried into practical effect, to be
enrolled in Her Majesty's High Court of Chancery within six calendar months
next immediately after the date of the said herein in part recited Letters
Patent, as, reference being thereunto had, will more fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
Samuel Morris, do hereby declare that the nature and particulars of my said

page_text: Invention, and the manner in which the same is to be performed and carried
into practical effect, are particularly set forth, described, and ascertained in
and by the following description or Specification, reference being had to the
Sheet of Drawings hereunto annexed and forming part of my said Specification,
on which Drawings the same letters of reference are used to denote similar
parts where different views or diagrams are shewn.
My Invention consists of improvements in the construction of vessels for
generating steam, commonly called steam boilers, by which improvements I
combine all the advantages hitherto gained by two or more flues, combustion
chamber, and a number of tubes, with a ready means of access to the interior
of the combustion or mixing chamber where a combustion of the gases takes
place, by which access the flues and tubes can be easily examined, cleaned, and
repaired, thus providing against accidents which so often occur to boilers where
such ready and easy means of examining the interior thereof and repairing the
injured parts do not exist. The construction and arrangement of my improved
boiler are shewn in the accompanying Drawings, in which Figure 1 represents
a sectional elevation of the boiler, with two flues and a number of tubes,
separated by a combustion or mixing chamber, with my improved apparatus
under it; Figure 2, a section of the same through the combustion chamber,
showing the tubes at the back; Figure 3, a section through the same at A;
Figure 4, a plan thereof; and Figures 5, 6, 7, and 8, views of my said apparatus,
by which I gain access to the interior of the combustion chamber.
a repre-
sents the flues; b, the combustion chamber; c, the tubes; and d, my improved
apparatus which I attach to the bottom of the boiler under the combustion
chamber; e,
door in the said apparatus for the purpose of entering into the
interior to examine, clean, or repair the flues, tubes, &c. when necessary,
without disturbing any part or parts of the general construction of the boiler;
ff, are chairs or supports for the boiler, which may be made of iron, brick, or
any suitable metal or material, and which will entirely dispense with the usual
method of a large quantity of brickwork for the seat of the boiler; and by
this advantage the exterior of the boiler can be easily examined as well as the
interior, as before stated.
This my improved apparatus may be made of sheet iron, copper, brass, or
any suitable metal, but as a general rule a metal the same as the boiler will
be found most convenient; it may be rivetted, screwed, or otherwise fastened
to the boiler, and the door or entrance e may be placed endways or sideways
with the boiler as will be found most convenient for entering, but where
practicable it will be found most useful to face either side of the boiler, as
the fireman can thus clean it with less trouble than if fixed in any other

page_text: position. I also fix a valve or small opening in this apparatus to admit a little
air, which will materially assist the combustion of the gasses. It is evident
that this improved apparatus will answer the double purpose of an entrance
box and dust chamber, as the refuse, dirt, and rubbish will fall and collect in
it, and be easily drawn out by the fireman without disturbing the boiler, or
even stopping its operations. It is also applicable to circular, Butterby, or
any shaped boilers that have a combustion chamber, and may rest on iron
supports, as shown in the Drawings, or be built up in the usual manner with
brickwork. When desired, all the usual apparatus of valves, steam guages,
discharge taps, &c. may be fixed or applied to boilers having my improved
entrance box or dust chamber in any convenient position; but as there are
such a variety of the said valves, steam guages, &c., and so many different
ways and positions of fixing the same, I have not shewn them in the Drawings
hereunto annexed, considering it better to leave the same to each person's
particular judgment and discretion.
Having now fully described the nature and particulars of my said Invention,
I desire it to be distinctly understood that I do not confine myself to the exact
shape or details of this my improved apparatus, as the same may be varied or
modified without departing from the principle of my said Invention; but
what I claim is, the placing or fixing an apparatus for the purposes of an
entrance box and dust chamber under the combustion chamber, as herein
described.
In witness whereof, I, the said Samuel Morris, have hereunto set
my hand and seal, this Thirtieth day of November, One thousand
