page_text: LETTERS PATENT to George Spencer, of 8, Alpha Road, New Cross,
Deptford, for the Invention of "IMPROVEMENTS IN THE EXTERNAL COVERINGS
OF ROOFS AND WALLS OF BUILDINGS AND SHEDS, AND IN THE WINDOWS OF SUCH
BUILDINGS AND SHEDS."

PROVISIONAL SPECIFICATION left by the said George Spencer at the
Office of the Commissioners of Patents, with his Petition, on the
26th September 1854.
I, GEORGE SPENCER, of 3, Alpha Road, New Cross, Deptford, do hereby
declare the nature of the Invention for "IMPROVEMENTS IN THE EXTERNAL
COVERINGS OF ROOFS AND WALLS OF BUILDINGS AND SHEDS, AND IN THE WINDOWS
OF SUCH BUILDINGS AND SHEDS," to be as follows:-
My improvements consist in the use of corrugated plates of glass, either
plain or colored, in the roofs and walls of railway sheds and conservatories, or
other buildings where light and lightness of appearance is required. For roofs
I use the corrugated glass plates, in lieu of the slates and boards and flat
glass plates now used in roofs, or they may be used in combination with them.
For walls I fill in the space between the standards that support the roofs
by corrugated plates of glass, or I cover the entire external surface with the
corrugated plates of glass. For windows and sky-lights I use the corrugated
plates of glass for the entire space of the window, with or without sash bars.

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GEORGE

WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-sixth day, of September, in the year of our
Lord One thousand eight hundred and fifty-four, in the eighteenth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said George Spencer, Her special licence that I, the said George Spencer,
my executors, administrators, and assigns, or such others as I, the said
George Spencer, my executors, administrators, and assigns, should at any
time agree with, and no others, from time to time and at all times thereafter
during the term therein expressed, should and lawfully might make, use,
exercise, and vend, within the United Kingdom of Great Britain and Ireland,
the Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN THE
EXTERNAL COVERINGS OF ROOFS AND WALLS OF BUILDINGS AND SHEDS, AND IN
THE WINDOWS OF SUCH BUILDINGS AND SHEDS," upon the condition (amongst
others) that I, the said George Spencer, by an instrument in writing under
my hand and seal, should particularly describe and ascertain the nature of
the said Invention, and in what manner the same was to be performed, and
cause the same to be filed in the Great Seal Patent Office within six calendar
months next and immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said George Spencer, do hereby declare
the nature of the said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement thereof (that is to say):
-
My improvements consist in the use of corrugated plates of glass, either
plain or coloured, in the roofs and walls of railway sheds and conservatories,
or other buildings where light and lightness of appearance are required. For
roofs I use the corrugated glass plates, in lieu of the slates and boards and
flat glass plates now used in roofs, or they may be used in combination with
them. For walls I fill in the space between the standards that support the
roofs with corrugated plates of glass, or I cover the entire external surface
with the corrugated plates of glass. For windows and sky-lights I use the
corrugated plates of glass for the entire space of the window, with or without
sash bars.
In the Drawing, Figure 1. shows a roof for a railway shed; Figures 2 and 2*

page_text: shew details of the same. A is the rafter; B and B form the portion to
which the corrugated plates of glass are attached by means of the angle iron
D. Figure 3 shews a roof, with the corrugations arranged at right angles to
the rafter, forming what is called in England step corrugations. (a) is rafter;
(b) is a piece of wood secured to rafter, to which the pieces of wood (f) for
supporting the corrugated plates are attached; the pieces of wood (e) and (d),
being secured to the piece (6), as shewn, retain the glass in its position without
bolts. I do not confine myself to the exact shape of the glass shewn, or to
the details of arrangement.
In witness whereof, I, the said George Spencer, have hereunto set mv
hand and seal, this Twenty-sixth day of March, in the year of our
Lord One thousand eight hundred and fifty-five.
GEORGE SPENCER. (L.s.)
Witness,
