Year: 1833

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JOHN
SQUIRES, of Paddington Baron, Engineer, and FRANCIS MACERONE, of Upper
George Street, Bryanstone Square, Esquire, send greeting.
WHEREAS His present most Excellent Majesty King William the Fourth,
by His Letters Patent under the Great Seal of Great Britain, bearing date at
Westminster, the Eighteenth day of July, in the fourth year of His reign, did,
for Himself, His heirs and successors, give and grant unto us, the said John
Squires and Francis Macerone, His especial licence, full power, sole privilege
and authority, that we, the said John Squires and Francis Macerone, our exors,
admors, and assigns, or such others as we, the said John Squires and Francis
Macerone, our exors, admors, or assigns, should at any time agree with, and no
others, from time to time and at all times during the term of years therein ex-
pressed,shouldandlawfullymight make, use, exercise, and vend, within England,
Wales, and the Town of Berwick upon Tweed, our Invention of "CERTAIN
IMPROVEMENTS ON BOILERS FOR GENERATING STEAM;" in which said Letters Patent
is contained a proviso that we, the said John Squires and Francis Macerone,
or one of us, shall cause a particular description of the nature of our said
Invention, and in what manner the same is to be performed, to be inrolled in
His said Majesty's High Court of Chancery within six calendar months next
and immediately after the date of the said in part recited Letters Patent, as in
and by the same, reference being thereunto had, will more fully and at large
appear.

page_text: DESCRIPTION OF THE DRAWING.
Figure 1 represents a series of nine cylinders a, a, connected top and
bottom by short pipes b, b, which are attached to the respective cylinders by
screws, nuts, and washers, as shewn in the Drawing, or they may be attached
by riveting or otherwise. It will be seen in this Figure that the three
cylinders in the middle are shorter than those on each side. This arrangement
forms the front series of cylinders. Figure 2 represents another series of
cylinders combined by pipes b, these cylinders being all of the same length,
which series forms the back of the boiler. Figure 3 represents another series
of cylinders a, seven of which are shorter than the others, and are those which
stand directly over the file or fuel, and of this last series each of the succeeding
series from front to back of the boiler is constructed, that is to say:-Numbers
1, 2, 3, 4, 5, 6, and 7, are formed of the series, Figure 3, and are connected by
pipes bat top and bottom, as are shewn in Figure 4, which Figure represents
the boiler as made up of the combined series of cylinders. c, Figures 3 and 4,
represent connecting pipes between the lower ends of the cylinders a, by means
of which the water may readily flow from one side of the boiler to the
other, and keep the water in all the cylinders a to an equal level. These
pipes a also act as fire bars, there being other fire bars placed between the
pipes c, as is shewn by dotted lines in Figure 4. In Figure 4, d is a steam
chamber, having steam connecting pipes e, from each of the series of cylinders
a, as shewn in this Figure, and from any convenient part of the steam chamber,
the steam pipe to the engine may be connected. Figure 5 shows the boiler
complete, having its outer casing; having guage cocks f, to indicate the level of
the water in the various series of cylinders a, and also shews the lever of an
ordinary safety valve placed on any of the cylinders a. The fuel is supplied to
the fire-place or furnace at the point g, which is a door capable of being lifted,
there being an inclined shoot or hopper below to direct the fuel to the fur-
nace; h is the fire door, and i the door to the ash-pit; j is a cock for
blowing out the boiler, to prevent the lodgement of sediment in the

page_text: cylinders a. The Drawing represents the cylinders a as being about four
inches diameter, and four feet long, but it will be evident that these dimensions
may be varied without departing from the nature of our Invention, as may also
the number of cylinders which compose each of the series, Figures 1, 2, and 3,
and the boiler may be made of other figures than a square.
Our Invention, consists of a combination of cylinders a, in the manner
above described for forming a boiler, particularly applicable as a light at the
same time powerful boiler, which will be found highly valuable for the purpose
of locomotive carriages and other uses.
In witness whereof, I, the said Francis Macerone, have hereunto set
my hand and seal, this Eighteenth day of January, in the year of our
Lord One thousand eight hundred and thirty-four.
AND BE IT REMEMBERED, that on the Eighteenth day of January, in
the year of our Lord 1834, the aforesaid Francis Macerone came before our
said Lord the King in His Chancery, and acknowledged the Specification
aforesaid, and all and everything therein contained and specified, in form
above written. And also the Specification aforesaid was stamped according
to the tenor of the Statute made for that purpose.
Inrolled the Eighteenth day of January, in the year of our Lord One
thousand eight hundred and thirty-four.
