A MANUFAC- TURE OF GLASS TILES
Year: 1845

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, Jonn
RUSSEL, of the City of Edinburgh, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, under the Great
Seal of the United Kingdom of Great Britain and Ireland; bearing date at
Westminster, the Thirtieth day of December, in the ninth year of Her
reign, and in the year of our Lord One thousand eight hundred and forty-five,
did, for Herself, Her heirs and successors, give and grant unto me, the said
John Russel, my exors, adññors, and assigns, or such others as I, the said
John Russel, my exors, adññors, and assigns, should 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 Berwick-upon-Tweed, my Invention of "A MANUFAC-
TURE OF GLASS TILES;" in which Letters Patent there is contained a proviso
obliging me, the said John Russel, by an instrument in writing under my
hand and seal, particularly to describe and ascertain the nature of my said
Invention, and in what manner the same is to be performed, and to cause
the same to be enrolled in Her Majesty's High Court of Chancery within six
calendar months next and immediately after the date of the said 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, I, the' said
John Russel, do hereby declare that this present Instrument in writing, with

page_text: the Plan and Drawings hereunto annexed, contains a true and particular
description of my said Invention, and that the same is as follows:-
I form pieces or sheets of glass of any convenient size, with two of their
respective opposite sides bent or turned up so as to form flanges varying from
about half an inch to one inch, according to the size of the tile, standing perpen-
dicular to the plane of the sheets, or until they form any suitable angle, either
outwards or inwards, the larger end of the tile having the deeper flange, as
shewn in the accompanying sections, marked Figures 1, 2, 3, and sometimes
I bend the two sides in the form of a curve, as shewn in Figure 4; but I wish
it to be understood with reference to the above Figures No. 1, 2, 3, and 4,
that I do not intend to confine myself to the precise angles or curves there
shown, but it will be obvious that the angle or curve may be varied and still
may be suitable for the purposes of roofing, as herein described. And for the
purpose of forming the pieces or sheets of glass with flanges, as before men-
tioned, I make use of any of the known methods of bending or of pressure
into moulds or of casting glass. I form the flanges or turned up edges in
such a manner that the plane or surface of the glass is broader at one
extremity than at the other, as shewn in Figure 8, or a recess may be formed
in the flanges at both ends in reverse directions, as shewn in Figure 6, the
object being that the smaller and bottom end of the tile may fit into
and rest upon the broader and upper end of the one immediately below
it. I also form angular tiles in the same manner for hips or cupolas by
bending or turning up, in the manner before described, the edges of the
converging sides. Tiles of the above forms may be applied to the covering of
roofs of conservatories or other horticultural buildings and arcades, to form
skylights or cupolas, and, if formed of colored, obscured, or opaque glass, may
be applied to roofing purposes generally. The roof for sustaining the tiles
may consist of rafters, as shown in Fig. 7, spanning the building in the usual
manner, to which laths, as shown in the same Figure, of wood or metal, of
suitable dimensions, running parallel to the side walls, would be attached at
such distances from each other as to come under the overlapping portion of
the tiles. The tiles would then be laid in parallel rows up and down the roof
in the direction of the rafters or couples, and side by side, as shown in Fig. 8.
The space left between the flanges of the two rows of tiles may be filled with
putty or other suitable cement, and be covered over by a hollow bead of metal,
glass, or other suitable material, as shown in Fig. 9. The tiles thus laid may
be secured to the roof by various methods. The metal bead over the flanges
might be made to answer this purpose by being screwed down to the laths
with screws and nuts, having elastic collars of any suitable substance, to allow
