Sealed the 4th August 1874, and dated the 18th May 1874.
PROVISIONAL SPECIFICATION left by the said Alfred William Georgo
Weeks, George Deal, George Lillywhite, and Alexander Oliver
Launders at the Office of the Commissioners of Patents, with their
Petition, on the 18th May 1874.
We, ALFRED WILLIAM GEORGE WEEKS, GEORGE DEAL, GEORGE
LILLYWHITE, and ALEXANDER Oliver LaundERS, carrying on Business
under the Style of J. Weeks & Co., Horticultural Builders and Hot-
water Apparatus Manufacturers, King's Road, Chelsca, in the County
of Middlesex, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN HOT-WATER BOILERS AND HOT-WATER APPARATUS APPLICABLE

page_text: TO THE CIRCULATION OF HOT WATER, PART OF WHICH IMPROVEMENTS ARE APPLICABLE
TO OTHER PURPOSES," to be as follows:-
_
This Invention relates to improvements on the tubular boiler for
which we obtained Letters Patent bearing date Jan 28th, 1870, and
numbered 256, the object being to improve the circulation of the water
in such boilers by the insertion of a solid or hollow diaphragm or
divisional waterway of cast or wrought iron or other material at any
point between the top and bottom castings of the boiler in a manner
either unattached or connected to one or more rows of tubes or one or
more of the tubes which constitute the boiler, also upon one or more
rows or one or more of the tubes which constitute the furnace bars.
And, Secondly. To improve and facilitate the mode of setting such
boilers by making of any material the diaphragm of such convenient
form that when applied to the boiler it shall constitute part of the
smoke flue, and thereby cause the caloric to be more effectually
absorbed, and prevent its escape into the smoke flue or chimney.
Thirdly. In addition to the diaphragm we purpose to fix to or form on
the tubes plates of wrought or cast iron or other material of any size
suitable to the spaces between the tubes of the boiler, such plates to be
fixed, cast, or otherwise attached either with or without the diaphragm
in a manner most suitable to the particular construction of boiler to
which they are to be applied.
Fourthly. We further improve upon existing systems of circulating.
hot water by a novel arrangement of a pipe or pipes with suitable con-
nections, varying according to size, whereby the water after having been
heated in the boiler is made to circulate either wholly or partly through
the bottom bar tubes, which are used as a superheater, and from which
the water flows direct into the apparatus, the advantage of which is
that the flow pipe issues from the lowest instead of the highest point of
the boiler as heretofore, and thus obviates the necessity of a deep stoke
hole, while in cases where a variety of levels of pipes for apparatus are
required, the water would be taken from any higher point of the
hoiler

filed by the said Alfred William George Weeks, George Deal,
George Lillywhite, and Alexander Oliver Launders in the Great
Seal Patent Office on the 16th November 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, ALFRED
WILLIAM GEORGE WEEKS, GEORGE DEAL, GEORGE LILLYWHITE, and
ALEXANDER OLIVER LAUNDERS, carrying on Business under the Style of
J. Weeks & Co., Horticultural Builders and Hot-water Apparatus
Manufacturers, King's Road, Chelsea, in the County of Middlesex, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Eighteenth day of May, in the year of
our Lord One thousand eight hundred and seventy-four, in the thirty-
seventh year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto us, the said Alfred William George Weeks, George'
Deal, George Lillywhite, and Alexander Oliver Launders, Her special
licence that we, the said Alfred William George Weeks, George Deal,
George Lillywhite, and Alexander Oliver Launders, our executors, admi-
nistrators, and assigns, or such others as we, the said Alfred William
George Weeks, George Deal, George Lillywhite, and Alexander Oliver
Launders, our executors, administrators, and assigns, should at any time
agree with, and no others, from time to time and at all times there-
after 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 Inven-
tion for "IMPROVEMENTS IN HOT-WATER BOILERS AND HOT-WATER APPARATUS.
APPLICABLE TO THE CIRCULATION OF HOT WATER, PART OF WHICH IMPROVEMENTS
ARE APPLICABLE TO OTHER PURPOSES," upon the condition (amongst others):
that we, the said Alfred William George Weeks, George Deal, George
Lillywhite, and Alexander Oliver Launders, our executors or adminis-.
trators, by an instrument in writing under our, or one of our, 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.

page_text: NOW KNOW YE, that we, the said Alfred William George Weeks,
George Deal, George Lillywhite, and Alexander Oliver Launders, do
hereby declare the nature of our said Invention, and in what manner
the same is to be performed, to be particularly described and ascertained
in and by the following statement and accompanying Drawings, that is
to say :-
Our Invention consists of certain hollow castings attached to upright.
tubular boilers, together with certain stop or flue plates, which utilizes
the heat, prevents the escape of unconsumed gases, and generally
increase the power of the boilers, while at the same time lessening the
consumption of fuel and economizing labour.
Figure 1 represents a plan of the bottom castings of boiler.
Figure 2 represents the upper and lower sides respectively of top
castings of boiler, full particulars of which, together with the furnace.
bars and mode and use of the various connections, are fully set forth in
our Patent, No. 256, dated 28th January 1870, and from the fact that
these remain unaltered it is not our intention here to enlarge upon
them.
Figure 3 represents the top of diaphragm W, which constitutes the
special feature of this Patent. It may be described as consisting of
two semicircular horizontal hollow chambers with ordinary waterways,
having sockets or nozzels on either side for the reception of the tubes
forming the boiler.
It should here be stated that each of the plans indicate the dia-
phragm W as being connected to the outer ring of tubes only, although
in some instances it may be desirable to enlarge and connect it to the
inner ring also; this however in no way affects the object sought to be
achieved, as by either of these arrangements, that is to say, whether one
or both the rings of tubes forming the boiler be connected to the
diaphragm, the separate plates or flanges, as shown at V, Figure 3,
should be so placed as to stop up the spaces between the inner tubes,
and thereby prevent the smoke and unconsumed gases passing imme-
diately from the furnace into the chimney. Figure 7 shows the front
elevation and Figure 8 the side elevation of such flue plates, the length
and width of same being regulated by the height and width of openings
between tubes of boiler to be stopped...

page_text: The diaphragm, instead of being secured to the boiler by means of
sockets as before stated, may, in cases where the boiler is in one body of
metal be made to form part and parcel of the one casting, or in other
cases it may be secured in any manner deemed best.
Having now described the nature of our said Invention, and the
manner in which the same is to be performed, we declare that we claim
as our Invention,—-
First. The manufacture of a solid or hollow water diaphragm in one
or more castings or pieces of iron or other suitable material, specially
adapted to tubular and other boilers.
Second. The arrangement and mode of connecting such diaphragm,
whereby greater heat is ensured and a less quantity of fuel consumed.
Third. The application of our improved form of flue stops in con-
junction with such diaphragm, which prevent the escape of unconsumed
gases into the chimney.
Fourth. That by the introduction of this diaphragm the heating
surface, and consequently the power of the boiler, is materially increased
without adding to its size.
Lastly. We claim by the use of this diaphragm to effect a great
economy of fuel and labour, a more intense heat in the furnace, the con-
sumption of otherwise waste gases, and a prevention of the fouling of
the boiler, together with an increased duration of the fire without
attendance.
In witness whereof, we, the said Alfred William George Weeks,
George Deal, George Lillywhite, and Alexander Oliver Launders,
have hereunto set our hands and scals, this Sixteenth day of
November, in the year of our Lord One thousand eight hundred
and seventy-four.
