VERTICAL STEAM BOILERS."
"IMPROVEMENTS IN
The first part of my Invention consists in placing two, three, or more vertical.
flued tubes within the shell of a vertical boiler, each fluc having at its lower end a
furnace.
I connect each furnace with the outside of the boiler by a short conical flanged
tube, and I rivet the larger flanged end to the outer shell of the boiler; this forms
the firing hole, and is fitted with a door.
In each vertical flued tube I place conical or parallel cross tubes, which connect
the water space of the boiler and strengthen the flues. The flucs are rivetted to'
the bottom plate of the boiler.
The crown of each flued tube is forined of an annular plate, corrugated to allow
for expansion and contraction, in the centre of which is the uptake" rivetted to
the top plate of the boiler, which carries the products of combustion to the
smoke box.
The smoke box is formed by placing the top of the boiler at one foot or other
desired distance from the upper end of the shell.
The upper part of the smoke box may be covered by a dish plate or brickwork,
and the gases may be carried off from the top or from the side of the smoke box.
The top and bottom of the boiler may be stayed by angle iron and plates to the
shell.

VERTICAL STEAM BOILERS."
"IMPROVEMENTS IN
The first part of my Invention consists in placing two, three, or more vertical
flued tubes within the shell of a vertical boiler, each flue having at its lower end a
furnace. I connect each furnace with the outside of the boiler by a short flanged
ube, and I rivet the one flanged end to the outer shell of the boiler, and one end
to the furnace or flue; this forms the firing hole, and is fitted with a door. In
each vertical flued tube I place conical or parallel cross tubes, which connect the
water space of the boiler and strengthen the flues. The flues are rivetted to the
bottom plate of the boiler. The crown of each flued tube is formed of an annular
plate, corrugated to allow for expansion and contraction, in the centre of which is
the uptake rivetted to the top plate of the boiler and to the crown of the flue,
which carries the products of combustion to the smoke box. The smoke box is
formed by placing the top of the boiler at one foot or other desired distance from
the upper end of the shell. The upper part of the smoke box may be covered by a
dish plate or brickwork, and the gases may be carried off from the top or from the
side of the smoke box.
The top and bottom of the boiler may be stayed by angle iron and plates to
the shell.
And in order that my Invention may be fully understood, and readily carried
into operation, I will proceed to describe the accompanying two Sheets of Drawings,
reference being had to the Figures and letters marked thereon.
On Sheet 1, Fig. 1 is an elevation in section of a vertical boiler made according
to my Invention with four vertical flued tubes; Fig. 2 is a cross section of the
same, showing the grate bars; Fig. 3 is a vertical section of part of the same.
Fig. 4 is an elevation of the boiler; and Fig. 5 is a cross section, showing the
cross tubes fitted in the vertical tubes.
a is the shell of the boiler; b is the vertical flued tubes; c, the cross tubes,
and d the furnace bars; e is the bottom plate of the boiler, to which the flues b
are rivetted; f, f, are flanged tubes which form the firing holes for the furnaces
at the bottom of the vertical tubes. Each vertical flued tube has an uptake g
rivetted to the crown of the tube and to the top of the boiler h. I make the
crowns of the vertical tubes corrugated, as shown at i, Fig. 3, to allow for expansion
and contraction; is the smoke box, and is the flue which carries off the
products of combustion to the chimney.
On Sheet 2, Fig. 6 is an elevation partly in section of my improved boiler; and
Fig. 7 is a plan of the same, showing two flues and m communicating between
the smoke box and the chimney. I fit dampers at the top, so that either of the
flues may be used. In the flue I place pipes n, through which the feed water is
supplied to the boiler. I am thus enabled to heat the water before admitting it to
the boiler when desired.
Although I have shown the vertical flued tubes with cross tubes for the
circulation of water, in some cases I dispense with the cross tubes, and the
arrangement and construction of the parts may be varied.

page_text: Having stated the nature of my Invention, and described the manner of performing
the same I declare that I claim,-
A vertical boiler having several vertical flued tubes, each provided with a furnace,
and with or without cross tubes, substantially as shown and described.
In witness whereof, I, the said William Lord, have hereunto set my hand
and seal, this Nineteenth day of July, in the year of our Lord One thousand
eight hundred and eighty one.
WILLIAM LORD. (L.S.)
