I, CHARLES FREDERIC VASSEROT, of 45, Essex Street, Strand, London,
Patent Agent, do hereby declare the nature of the said Invention for "IM-
PROVEMENTS IN GLASS ROOFS, SKYLIGHTS, WINDOWS, AND OTHER GLASS STRUCTURES,"
(a communication from Pierre François Rolier Gonsault, of Montargis (Loiret),

the panes or sheets of glass by means of a flexible band, the said joint being
either air-tight, or made to receive and convey outside the condensed moisture
from the inside. This band is made of lead or of any other flexible and
resisting metal; it is furnished with two opposite grooves separated by an
interval or space which forms a gutter. The two panes or sheets of glass to
be joined, which may be of any shape or thickness, are enchased in the two
grooves, and they are kept by the simple pressure of the grooves' edges.

page_text: The water produced by the condensation may be conveyed outside through
small holes, made at suitable places and distances in the space or gutter
between the grooves.

NOW KNOW YE, that I, the said Charles Frederic Vasserot, do hereby
declare the nature of the said Invention, and in what manner the same is
to be performed, to be particularly described and ascertained in and by the
following statement :-
This Invention consists in. joining together the panes or sheets of glass by
means of a flexible band, the said joint being either air-tight, or made to

page_text: receive and convey outside the condensed moisture from the inside. This
band is made of lead or of any other flexible and resisting metal; it is
furnished with two opposite grooves separated by an interval or space which
forms a gutter. The two panes or sheets of glass to be joined, which may be
of any shape or thickness, are enchased in the two grooves, and they are kept
by the simple pressure of the grooves' edges.
The water produced by the condensation may be conveyed outside through
small holes, made at suitable places and distances in the space or gutter
between the grooves.
In order more clearly to illustrate the above description, I have appended
the accompanying Drawings, of which Figure 1 is a section, nearly twice the
actual size of two squares of glass a, a, fixed into the strip or band; the gutter
being formed by the double curve in the strip, within which is the hole or
aperture c for allowing the moisture to escape. Figure 2 is a plan and section
of the said strip or band by itself.
In witness whereof, I, the said Charles Fréderic Vasserot, have here-
unto set my hand and seal, this Twenty-sixth day of January, in
the year ofour Lord One thousand eight hundred and fifty-nine.
CHS. FRED. VASSEROT. (L.S.)
