IMPROVE- MENTS IN FIRE-BACK BOILERS
Year: 1878

page_text: LETTERS PATENT to James Fagan, of Number 16, Cavendish Street, Skipton,
in the County of York, Plumber and Glazier, for the Invention of "IMPROVE-
MENTS IN FIRE-BACK BOILERS."
Sealed the 16th August 1878, and dated the 8th May 1878.
PROVISIONAL SPECIFICATION left by the said James Fagan at the Office
of the Commissioners of Patents on the 8th May 1878.
JAMES FAGAN, of Number 16, Cavendish Street, Skipton, in the County of
York, Plumber and Glazier. "IMPROVEMENTS IN FIRE-BACK BOILERS."
This Invention relates to certain improvements in fire-back boilers, whereby the
heat only from the fire is passed around the boiler composed of two, three, or more
sections. standing in cast-iron framework, and so arranged that the heat on drawing
the damper passes under the first section and back over the top of such section,
and under the second, over the top of the second, and under the third, in the case
of three sections, and into main flue.
Hitherto fire-back boilers have been placed in such a position that the flue
leading under the boiler is liable when in use to become choked up with cinders
and ashes, thus necessitating cleaning out in order to make the boiler effective.
This duty is constantly neglected, and in consequence, the heated water is not of a
sufficiently high temperature.
By my arrangement no ashes can possibly get into the flue passages, and for the
cleaning out of soot a small opening in the cast-iron framework is arranged for the
purpose.
On closing the damper the heat would pass up the chimney in the ordinary way,
thus giving control of heating any amount of water for bath and domestic purposes,
and at the same time insuring a comparatively unlimited supply at a great saving
of fuel and of labor involved in cleaning out.

JAMES FAGAN, of Number 16, Cavendish Street, Skipton, in the County of
York, Plumber and Glazier. "IMPROVEMENTS IN FIRE-BACK BOILERS."
"
This Invention relates to certain improvements in fire-back boilers, whereby the
heat from the fire in an ordinary range is passed around the boiler composed of
two, three, or more sections standing in cast-iron framework, so arranged that the
heat on drawing the damper fixed over the top of the boiler in the cast-iron frame-
work passes under the first section, round the back, and over the top of such 1
section, and under the second, over the top of the second, and under the third, in
the case of three sections, and thence unto the chimney flue.
Hitherto fire-back boilers have been placed in such a position that the flue
leading under the boiler is liable when in use to become choked up with cindors
and ashes, thus necessitating cleaning out in order to make the boilers effective. 1
This duty is constantly neglected, and in consequence the heated water is not of a
sufficiently high temperature.
By my arrangement no ashes can possibly get into the flue passages; and for the
purpose of cleaning out the soot from off the various sections of the boiler a small
opening is arranged in the front portion of the cast-iron framework, which is fitted
with a door or cover plate, which when removed sufficiently exposes the boiler, so
that the same can be cleaned.
On closing the before-named damper the communication from the fire around
the sections of the boiler with the chimney is stopped, and the heat from the fire
would pass in front of the framework to the chimney in the ordinary way, thus :
giving control of heating any amount of water for bath and domestic purposes,
and at the same time insuring a comparatively unlimited supply at a great saving
of fuel and labor involved in cleaning out the ashes.
Such being the nature and object of this my Invention, I will now proceed to
describe the saine in detail; and in order that the same may be fully understood I.
have hereunto annexed one Sheet of Drawings, and have marked the same with
letters of reference.
Figure 1 represents an end view of my improved fire-back boiler with one of the
side's plates removed; Figure 2 is a front elevation of the same with the front
plate removed.
'
The Drawings shew my improved fire-back boiler, which is composed of three
sections, indicated by the letters A, and fixed at the back of an ordinary fire-
range B.
I do not confine myself to the number of sections A, as the boiler may be com-
posed of more or less, according to requirements.
The sections A are connected together by one or more pipes C, and the boiler is
placed in a perpendicular or diagonal direction, and enclosed in a cast-iron frame-
work D fixed at the back of the fire-range. At one or both ends of the top and
bottom sections connections can be made with the supply and outlet pipes E, E.
At the top of framework D is placed a sliding damper F, which when drawn out,
as shewn in Figure 1, will open the communication from the fire in the range B
through the opening G, and around the sections of the boiler in the directions of
the arrows to the chimney flue H; thus, by the application of my improved boiler
the heat that usually passes direct up the chimney is utilised, and warms the water
contained in the boiler.
When the boiler is not required for use the damper F is slided back, which closes
the opening J, and allows the heat to pass direct into the chimney.
If at any time the boiler is required to be taken out for repairs the front plate is
removed, and the unions K, K, on the inlet and outlet pipes E, E, are unscrewed.

page_text: The boiler is then free, and can be removed without disturbing the other fixtures of
the fire-range.
Having thus described in detail the nature and objects of my Invention, and the
manner of carrying the same into effect, I have to state that I do not confine
myself to the precise details already described and illustrated, but that what I
believe to be novel and original, and claim as the Invention secured to me by the
herein-before recited Letters Patent is, the arrangement of fire-brick boilers in com-
bination with the cast frame fixed at the back of an ordinary fire-range, which
frame is fitted with a damper for regulating the currant of heat, so as to pass
around the boiler or direct into the chimney, substantially in the manner herein-
before described, and illustrated by the accompanying Drawings.
In witness whereof, I, the said James Fagan, have hereunto set my hand
and seal, this Fifth day of November, in the year of our Lord One thousand
eight hundred and seventy-eight.
