IMPROVEMENTS IN THE MANUFACTURE OF GLASS
Year: 1851

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JAMES
TIMMINS CHANCE, of Birmingham, Gentleman, 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 Twenty-eighth day
of July, One thousand eight hundred and fifty-one, in the fifteenth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said James Timmins Chance, my exors, adiňors, and assigns, Her especial
licence, full power, sole privilege and authority, that I, the said James
Timmins Chance, my exors, admors, and assigns, or such others as I, the
said James Timmins Chance, my exors, admňors, 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, the Invention of "IMPROVEMENTS IN THE MANUFACTURE OF GLASS,"
partly invented by myself, and partly communicated to me by a certain
foreigner residing abroad; in which said Letters Patent is contained a
proviso that I, the said James Timmins Chance, shall cause a particular
description of the nature of the said Invention, and in what manner the
same is to be performed, by an instrument in writing under my hand and
seal, to be inrolled in Her 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.

is a transverse section, through the line B, B, shewing a traversing frame a.
Figure IV. is a plan of this frame, which travels on the rails x, a, and is moved
by the levers m, and has fixed upon its upper surface two sets of rails y, y,
whose guage coincides with that of the rails z, z, fixed in the flattening place;
suppose that the unoccupied set of rails y, y, coincide with z, z, the workman
at A, having finished the sheet or plate on the flattening stone or bed
b, pushes this stone or bed upon the rails y, y, into the part C of the kiln; the
assistant then moves the traversing frame in the direction B, B, until the set
of rails y, y, carrying the flattening bed b, coincides with z, z; when the
2

workman pulls this flattening bed b into the flattening place, and proceeds
with working upon it. At a convenient time he lifts the sheet or plate of
glass from the bed b¹, and deposits it either in the annealing arch upon or in a
suitable receptacle D, or on another bed according to the arrangements of the
particular kiln, as those acquainted with this branch of the manufacture of
glass will readily understand. The flattening beds may thus continue to be
interchanged in succession; I prefer that each of the flattening carriages should
have two flanged guide pullies, as at f, in Figure III., which may be placed so

page_text: as to turn freely upon the middle of each axle, and run upon central guide rails b,
instead of the wheels themselves having flanges; any slight inaccuracy of coin-
cidence between the guage of the rails y, y, and that of the rails, z, is thereby
rendered unimportant. The traversing frame may move on wheels turning in
stationary bearings instead of having wheels attached to it, and a revolving
frame might be substituted for the traversing one by modifying the arrange-
ment of the adjacent parts of the kiln. Figure V. represents the improved
fork or implement for lifting and transferring the sheets or plates of glass,
being a plan of its under surface. Figure VI. is a side view of one of the
prongs; 9, 9, are rollers fixed on the prongs and slightly projecting above the
upper surface.
Having thus described the nature of the said Invention, and the manner in
which the same is to be performed, I would have it understood that I do not
confine myself to the details herein described, so long as the peculiar character
of either part of the said Invention be retained; but what I claim is,--
First, the employing, in connection with the same flattening kiln, more than
one flattening stone or bed not connected together by a common supporting
base or framework, and in such manner that two flattening stones or beds
aforesaid can be interchanged without one of them having to pass directly
over or under the other; and,
Secondly, the combining rollers with the implements used for lifting and
transferring sheets or plates of glass, as aforesaid.
In witness whereof, I, the said James Timmins Chance, have hereunto
set my band and seal, this Twenty-fourth day of January, in the year
of our Lord Que thousand eight hundred and fifty-two
