IMPROVEMENTS IN APPARATUS FOR HEATING WATER, GENERATING STEAM, AND CONSUMING SMOKE
Year: 1881

page_text: LETTERS PATENT to Robert Thomas Gillibrand, of Darwen, in the County of
Lancaster, Cotton Manufacturer, for an Invention of "IMPROVEMENTS IN
APPARATUS FOR HEATING WATER, GENERATING STEAM, AND CONSUMING
SMOKE."
PROVISIONAL SPECIFICATION left by the said Robert Thomas Gillibrand at
the Office of the Commissioners of Patents on the 29th October 1881.
ROBERT THOMAS GILLIBRAND, of Darwen, in the County of Lancaster, Cotton
Manufacturer. "IMPROVEMENTS IN APPARATUS FOR HEATING WATER, GENERATING
STEAM, AND CONSUMING SMOKE."
This Invention relates to improved apparatus to be employed for purposes
aforesaid, and is mainly designed for use in connection with boilers for generating
steam, but is also applicable as a heater of water for heating or warming buildings,
green houses, and the like.
Apparatus according to this my Invention comprise a boiler and furnace
connected by steam or hot water pipe, as the case may be, with a second steam or
hot water boiler placed at some little distance away from the boiler first refered to;
there is also a flue or smoke way leading from the furnace of the first boiler to the
flue or flues of the second boiler, and such smoke way is fitted with fire bricks or fire
clay slabs around and about which the smoke circulates during its passage from the
first to the second boiler, and near the latter in the smoke way is an opening or air
entrance, and there the smoke is fired and consumed within the flues of the second
boiler.

the said Robert Thomas Gillibrand in the Great Seal Patent Office on the
28th April 1882.
ROBERT THOMAS GILLIBRAND, of Darwen, in the County of Lancaster, Cotton
Manufacturer. "IMPROVEMENTS IN APPARATUS FOR HEATING WATER, GENERATING
STEAM, AND CONSUMING SMOKE."
This Invention relates to improved apparatus to be employed for purposes
aforesaid, and is mainly designed for use in connection with boilers for generating
steam, land or marine, but is also applicable as a heater of water for heating or
warming buildings, green houses, and the like.
Apparatus according to this iny Invention comprise a furnace connected by pipe
or flues with a steam or hot water boiler placed at some distance from the furnace.
The pipes referred to act as flues or smoke ways leading from the furnace through
the boiler, and such pipes or smoke ways are fitted with fire clay blocks or slabs;
these blocks or slabs are for the purpose of consuming the smoke, and to assist in
generating-steam, around-and-about which-the-heated gases circulate during its-
passage through the boiler. Along or in the furnace are openings or air entrances,
through or by aid of which the smoke is fired and consumed within the flues of
the boiler.
Such being the nature and object of this my said Invention, I will now describe
the same in detail, and in order that the Invention may be fully understood have
hereunto annexed a Sheet of Drawings illustrative thereof.
Fig. 1 is a sido elevation of apparatus constructed according to this my
Invention.
Fig. 2 is a front elevation.
Fig. 3 is a sectional elevation (transverse).
Fig. 4 is a longitudinal section shewing furnace or heating chamber within the
boiler.
Fig. 5 is a sectional plan of Fig. 4.
A is the furnace connected by pipes or flues B, B, with the steam or hot water
boiler C. The pipes B, B, act as flues or smoke ways leading from the furnace A
to the boiler, and such pipes or smoke way are fitted with fire clay blocks or fire
clay slabs D, D, of form (as shewn at Fig. 3 and 4), similar to interior of flue B, B,
but leaving passage way for heated gases from furnace A. The heat from fire clay
blocks or slabs D, D, aided by the form of the latter, which confine the smoke and
gasses passing around and along the said blocks or slabs effect the consumption of
smoke, the tubes E, E, surrounded by hot water admitting the necessary of
hot air. The supply of fire is through or by way of the doors F, F, until the fire is
thoroughly ignited, and the blocks or slabs D, D, are heated, whereon the doors F, F,
are sealed, and the after supply of fire is by way of the top feeds C, C, each of
which is provided, as shewn, with two slides H and J. In feeding the slide H will
be withdrawn and the space K filled with fuel; the slide H will then be closed and
the slide J opened, admitting the fuel to the furnace A without allowing entrance
of cold air, or of escape of smoke or gases from furnace during the charging the
latter. The fire is stirred or broken up by rod passed into the furnace by way of
the holes L, L.

page_text: At Fig. 4 and 5 the furnace A is shewn within the boiler and forming part
thereof as distinguished from Fig. 1, whereon the furnace is detached or separate
from the boiler proper.
Having thus fully described the nature and particulars of this my said Invention,
together with the manner in which the same is to be or may be performed or
carried into practical effect, I would have it understood that I lay no claim per se
to the application or use of a detached or separate furnace, as such is not new, but
what I do claim is,―
The construction and use in combination of furnace A, feed doors and feed ways
having slides H, J, air passage ways E, E, and fire clay blocks or slabs D, D, as
described and illustrated by Drawings annexed.
In witness whereof, I, the said Robert Thomas Gillibrand, have hereunto set
my band and seal, this Twenty fifth day of April, in the year of our
Lord One thousand eight hundred and eighty two.
