page_text: J. T. & E. CHANCE'S SPECIFICATION.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JAMES
TIMMINS CHANCE and EDWARD CHANCE, of Birmingham, Glass Manufacturers,
send greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Royal Letters Patent under the Great Seal of the United Kingdom of Great
Britain and Ireland, bearing date.at Westminster, the Fourteenth day of
February, One thousand eight hundred and forty-eight, in the eleventh year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto us,
the said James Timmins Chance and Edward Chance, our exors, adiñors, and
assigns, Her especial licence, full power, sole privilege and authority, that we,
the said James Timmins Chance and Edward Chance, our exors, adññors, and
assigns, or such others as we, the said James Timmins Chance and Edward
Chance, our exors, adiñiors, 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
expressed, should and lawfully might make, use, exercise, and vend, within
England, Wales, and the Town of Berwick upon Tweed, our Invention .of
"IMPROVEMENTS IN FURNACES AND IN THE.MANUFACTURE OF GLASS;" in which said
Letters Patent is contained a proviso that we, the said James Timmins Chance
and Edward Chance, 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 per-

page_text: formed, by an instrument in writing under our hands and seals, or under the
hand and seal of one of us, to be inrolled in Her 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.
NOW KNOW YE, that in compliance with the said proviso, we, the said
James Timmins Chance and Edward Chance, do hereby declare that the
nature of our said Invention, and the manner in which the same is to be
performed, are fully described and ascertained in and by the following state-
ment thereof, reference being had to the Drawing hereunto annexed, and to
the figures and letters marked thereon, that is to say:-
Our Invention consists, first, of an improvement in constructing reverbera-
tory furnaces. Secondly, our Invention consists of an improvement, in the
mode of transferring plates of glass into the annealing kiln or oven. And in
order that the Invention may be most fully understood, and readily carried into
effect, we will proceed to describe the means pursued by us.
DESCRIPTION OF THE DRAWINGS.
Figure 1 shews a longitudinal section; and Figure 2 a transverse section, of
a reverberatory-furnace constructed according to our Invention: In-construct-
ing reverberatory furnaces as heretofore practised, the heat having passed from
the fire through the furnace, and reverberated by the arch or upper. surfaces,
passes, away to a flue, and to the chimney, so that the heat having passed
through the furnace is no longer useful to the. furnace.. .Now the object of the
first part of our. Invention is to construct reverberatory furnaces,, that the heat
having passed through the furnace shall, by a flue or flues carried over the s
arch; aid in giving heat to the arch. The heat, in passing through the body of
the furnace g, g, is reverberated by the arch a, b, and then it passes back over.
the arch a, b, and under the arch e, f, and thence to the chimney. We would.
remark that reverberatory furnaces differ in some respects from each other,
according to the purposes to which they are applied. This part of our Inven-.
tion does not render it necessary that the construction of a reverberatory
furnace used for any particular purpose should be altered in construction
other than so far as the causing a flue or flues to be made over the rever-
beratory arch.
.
We will now describe the second part of our Invention, which consists of .a
mode of transferring plates of glass, particularly such plates as are of large
dimensions in proportion to the thickness, into the annealing oven or kiln.
Heretofore it has been usual to cause the plate, when sufficiently hard, to be

page_text: pushed into the furnace; this mode of, working genders it, necessary thätithe
glass should have lost a considerable portion of its heat in becoming sufficiently
hard..to allow of such pushing. Now by,drawing plates, into the kiln,an
advantage is derived.... In carrying out this part of our. Invention, we prefer
applying that. kind of annealing kiln which is specified-in the: Patent granted
to James. Timmins Chance, dated-June Fifteenth, One thousand eight hundred
and forty-seven, and we make an opening or openings through into the anneal-
ing oven or kiln, so that by introducing, tongs or instruments through such
hole or holes, the workman may take hold of a plate of glass and draw it into
the furnace; and this may be done in cases where the plates of glass would be
bent or injured if pushed into the kilu or oven.
Having thus, described the nature of our. Invention, and the manner in
which the same is to be performed, we would have, it understood that we do not
confine ourselves to the details herein described, so long as the peculiar cha-
racter of either part of our Invention be retained. But what we claim is,
first, the mode of constructing reverberatory furnaces herein described; and
secondly, we claim the moving of plates of glass into an annealing furnace, by
drawing in place of pushing, as herein explained.
In witness whereof, we, the said James Timmins Chance and Edward
Chance, have hereunto set our hands and seals, this Tenth day of
August, in the year of our Lord One thousand eight hundred and forty-
night
igned, sealed, and delivered by the
within-named James Timmins Chance
and Edward Chance in the presence
of
JAMES T. (L.s.) CHANCE.
EDWARD (L.S.) CHANCE.
