page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
BAILEY, of High Holborn, in the County of Middlesex, Ironfounder, send
greeting.
WHEREAS His most Excellent Majesty King George the Third did, by
His Letters Patent under the Great Seal of the United Kingdom of Great
Britain and Ireland, bearing date at Westminster, the Eleventh day of July,
in the fifty-eighth year of His reign, give and grant unto me, the said
William Bailey, my exors, adñiors, and assigns, His special licence, full
power, sole privilege and authority, that I, the said William Bailey, my
exors, adiñors, and assigns, 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, my Invention of "CERTAIN IMPROVE-
MENTS IN SASHES, SKYLIGHTS, AND FRAMES, GENERALLY USED FOR THE PURPOSE
OF RECEIVING, HOLDING, AND CONTAINING GLASS FOR THE ADMISSION OF LIGHT AND
THE EXCLUSION OF RAIN AND SNOW; AND ALSO FOR MAKING ROOPS OR COVERINGS
FOR HOUSES AND VARIOUS OTHER BUILDINGS;" in which said Letters Patent there
is contained a proviso that if I, the said William Bailey, shall not parti-
cularly describe and ascertain the nature of my said Invention, and in what
manner the same is to be performed, by an instrument in writing under my
hand and seal, and cause the same to be inrolled in His Majesty's High
Court of Chancery within six calendar months next and immediately after

page_text: the date of the said Letters Patent, that then the said Letters Patent should
be void, as in and by the same, relation being thereunto had, may more fully
and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
William Bailey, do hereby declare that the following is a particular descrip-
tion of the nature of my said Invention, and of the manner in which the same
is to be performed, that is to say :-
I take bars of iron of a breadth and thickness suitable to the size and
strength required. Having heated these bars red hot, as is usual in the
process of rolling iron, I pass them betwixt or through a pair of grooved rolls
turned by a steam engine or other power. The grooves in these rolls I make
in various forms, so as to impress on the bar a rebate and a moulding of
either double, hollow, astrigal, ovolo, or any other suitable moulding...
Secondly, I take the bars and fit them together so as to forin sashes, sky-
lights, or frames, and by the common methods of paint and putty or other
cement I attach the glass to the bars; or otherwise, after the bars are rolled
as aforesaid, by means of a grooved tool or swaige 1 bend these bars to any
form or shape required, but more particularly to any curvilinear shape, which
can only be effected in wood at an increased and heavy expence. And I
further declare the nature of my said Invention, on account or by reason of
the strength, lightness, durability, and adaptation to curvilinear forms is
advantageously applicable to the erection of hot-houses, green-houses, and all
kinds of conservatories, for the purpose of roofing. After having fixed the
frame of moulded bars, I take sheets of iron, tin, copper, or other suitable
metal, larger than will lie between the bars, and turn up on each side an edge
equal or about the depth of the rebate. I then take a strip of either of the
metals, grooved down the middle, of the width of the rebate and the two edges
of the sheets, so as to cover them, which I attach by means of rivits, screws,
or pieces of wire passing through the whole of them at convenient distances.
In like manner as aforesaid, I take bars of other metals, or compositions of
metals, and by means of grooved rolls form them with rebates and mould-
ings. But my Invention is particularly applicable to form iron sash bars
with impressed mouldings and rebates, and the bending them into curvilinear
shapes.
In witness whereof, I, the said William Bailey, have hereunto set my
hand and seal, this Eleventh day of January, in the year of our Lord
One thousand eight hundred and nineteen.
WILL (L.s.) BAILEY.
