page_text: I, GEORGE WINSTANLEY of the Gas Works, Coventry, in the County of
Warwick, Gas Engineer, do hereby declare the nature of my said Invention for
"IMPROVEMENTS IN THE REGENERATORS OF FURNACES, AND IN THE TILES USED
IN THE CONSTRUCTION OF THEM' to be as follows:-
"
This Invention has for its object the construction of the regenerators of furnaces,
and in the tiles used therefor, especially applicable to the heating of gas retorts,
with great simplicity, efficiency and economy.
The Invention consists in the use of grooved and tongued and perforated and
rabbeted tiles arranged as follows, one half of the regenerator, or the part placed
on one side of the generator and furnace only being described, the remaining part
being simply a duplicate placed on the other side. The space between the wall of
the generator and the side wall of the setting is divided into a number of passages.
This is effected by building into the walls in a horizontal course a quantity of
grooved and rabbeted tiles that stretch horizontally from one wall to the other.
Several rows of these tiles are used, one row being placed over the other, with a
space between each row, the tiles and spaces ranging from the front to the back or
cross wall of the setting. These passages are divided vertically into three separate
sets by tiles, the top and bottom edges of which have two flats and a half round,
or rectangular shaped tongue, which fits into a corresponding groove in the
horizontal tiles above and below. One end of these tiles has a tongue and the
opposite end a corresponding groove, so that when built together with the aid of
fire clay the passages may be made and remain perfectly gas and air tight. In the
centre of each horizontal tile and consequently in the centre of the middle passage
there is a line of perforations at intervals, the openings being placed directly above
each other in every alternate course, so that while the waste gases which descend
through these passages have a general downward course, their particular direction
is that of a zig zag one.
The currents of air are admitted from the front to the passages on each side of
the waste gas flue, and after travelling backwards and forwards till they reach the
top, and have become highly heated by contact with the waste gas flue, they there
join together in a passage common to both sides, and enter the furnace in a fit

page_text: condition to mix with the carbonic oxide and other gases, and produce vigorous
combustion. The waste gases enter the central passage or flue from above and
descend from one passage to the other through the perforations in each course of
the horizontal tiles, until they reach a broad passage below the level where the air
for the secondary combustion enters. They then descend at the front and enter
two passages, and finally make another descent and exit into the main flue.
Beneath the last two passages mentioned, several passages are formed to which air
is admitted from the front, and becoming greatly increased in temperature enters
the generator in a fit condition to promote the primary combustion.
Rabbeted tiles are not new, but rabbeted, and tongued and grooved, and
perforated tiles such as are herein described are new, as is also a regenerator
constructed entirely of tiles in the manner herein set forth.

"IMPROVEMENTS IN THE REGENERATORS OF FURNACES AND IN THE TILES USED
IN THE CONSTRUCTION OF THEM” and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following statement,.
reference being. had to the accompanying Drawings and to the letters and Figures
marked thereon :--
This Invention has for its object the construction of the regenerators of furnaces,
and in the tiles used therefor, especially applicable to the heating of gas retorts,"
with great simplicity, efficiency and economy.
In order that the Invention may be more easily understood Drawings are
attached hereto of which the following is a description. Fig. 1 is a plan of one of
the tiles used horizontally and having rabbets at A A and grooves of the form
shown at C, C, D being a perforation to be hereinafter alluded to. Fig. 2 is a
section through E, E Fig. 1.-Fig. 3 is an end elevation of Fig. 1.-Figs. 4 and 5
are end elevations of the vertical divisional tiles, one of which is exhibited in
Fig. 6. Fig. 7 is a part front elevation and part transverse sectional elevation of a
retort setting, the latter showing the arrangement of the tiles so as to form the
regenerator. Fig. 8 is a section through F, G Fig. 7.-Fig. 9 is a section F, I,
Fig. 7. Fig. 10 is a sectional plan through J, K Fig. 7, and Fig. 11 is a sectional
plan through L M Fig. 7.
The Invention consists in the use of the grooved and tongued and perforated
and rabbeted tiles. Figs. 1, 2, 3, 4, 5 and 6, arranged as follows, one half of the
regenerator, or the part placed on one side of the generator and furnace only being
described, the remaining part being simply a duplicate placed on the other side.
The space between the wall of the generator and the side wall of the setting is
divided into a number of passages. This is effected by building into the walls in a
horizontal course a quantity of grooved and rabbeted tiles Fig. 1, that stretch
horizontally from one wall to the other. Several rows of these tiles are used, one
row being placed over the other, with a space between each row, the tiles and
spaces ranging from the front to the back or cross wall of the setting. These
passages are divided vertically into three separate sets R, R, and S Fig. 7 by tiles
Figs. 4, 5 and 6, the top and bottom edges of which have two flats and a half
round. or rectangular, or other shaped tongue which fits into a corresponding
groove in the horizontal tiles Fig. 1 above and below. One end of these tiles has
a tongue and the opposite end a corresponding groove, so that when built together
with the aid of fire clay the passages may be made and remain perfectly gas and
air tight. In the centre of each horizontal tile, and consequently in the centre of
the middle passage there is a line of perforations D Figs. 10 and 11 at intervals,
the openings, being placed directly above each other in every alternate course as
depicted in Fig. 8, so that while the waste gases which descend through these
passages have a general downward course, their particular direction is that of a
zig zag one.
The currents of air are admitted from the front at N, N, Fig. 7. to the passages
on each side of the waste gas flue, and after travelling backwards and forwards
till they reach the top, and have become highly heated by contact with the waste
gas flue, they there join together in a passage. O Fig. 11 common to both sides and.
enter the furnace in a fit condition to mix with the carbonic oxide and other gases

page_text: and produce vigorous combustion. The waste gases enter the central passage or
flue from above and descend in the direction shown by the arrows in Fig. 8 from
one passage to the other through the perforations D in each course of the horizontal
tiles, until they reach a broad passage P below the level where the air for the
secondary combustion enters. They then descend at the front and enter two
passages and finally make another descent and exit into the main flue U. Beneath
the last two passages mentioned several passages Q Fig. 10 are formed, to which
air is admitted from the front and becoming greatly increased in temperature
enters the generator in a fit condition to promote the primary combustion.
Rabbeted tiles are not new, but rabbeted and tongued and grooved and perforated
tiles such as herein described aro new, as is also a regenerator constructed of such
tiles in the manner herein set forth.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed, I declare that what
I claim is,
1. Rabbeted, tongued, grooved and perforated tiles, as herein described and
shown on the Drawings.
2. Regenerators constructed with rabbeted, tongued, grooved and perforated
tiles as herein described and shown on the Drawings.
