PROVISIONAL SPECIFICATION.
An Improved Method or System of Glazing Opening Skylights or
other form of Windows.
We, SQUIRE FAWTHROP, and EDWIN FAWTHROP, of Haley Hill, Halifax,
in the County of York, Plumbers and Glaziers, do hereby declare the nature of
this invention to be as follows:-
Our invention has special reference to that system of glazing wherein glazing
bars and overlapping caps are used for the purpose of fixing glass without the use
of putty; and our improvements consist in combining with such systems of glazing,
a new or improved method of glazing skylights or squares of glass which may be
opened and closed, and our improvements apply whether such squares of glass are
made to open on the roof or sides of glazed structures.
In carrying out our invention we employ an astragal or supporting bar of the
shape in cross section shewn in Fig. 1 of the accompanying drawings. On or over
this astragal we place a glazing bar of the shape shewn in cross section Fig. 2, but
the central projection a on the left hand portion may be omitted. The edge of the
glass rests upon the projections with the central wing b overlapping same for the
purpose of keeping the glass down. The channels on each side of the central rib b
are employed to convey away water or condensed moisture. The under rib c of the
astragal or supporting bar, rests in a groove or channel on the glazing bar which
supports the adjoining sheets of glass and the astragal is indented as shewn at d
in Fig. 3 to permit the sheets of glass e to overlap each other.
Our improved glazing bar can be used for right and left sides of the glass, and
we arrange that the sheets of glass rest upon asbestos or other packing. The sheets
of glass are prevented from slipping downwards by a shoe or lip made secure in a
suitable position for that purpose. The supports of the glazing bar are suitably
hinged so as to permit of the glazed skylight being opened and closed by a suitable
arrangement of levers and rods.

An Improved Method or System of Glazing Opening Skylights or
other form of Windows.
We, SQUIRE FAWTHROP, and EDWIN FAWTHROP, of Haley Hill, Halifax,
in the County of York, Plumbers and Glaziers, do hereby declare the nature of
this invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
Our invention has special reference to that system of glazing wherein glazing
bars and overlapping caps are used for the purpose of fixing glass without the use
of putty; and our improvements consist in combining with such systems of glazing,
a new or improved method of glazing skylights or squares of glass which may be
opened and closed, and our improvements apply whether such squares of glass are
made to open on the roof or sides of glazed structures.
In order that our invention may be better understood, we will make reference to
the accompanying sheet of drawings illustrative thereof, wherein Fig. 1 is sectional
elevation of my improved system of glazing an opening skylight or other form of
window

page_text: A represents the astragals, on the top of which I place a glazing bar B
shewn on an enlarged scale in Fig. 2. The edges of the sheets of glass C rest
upon the projections a or upon a piece of asbestos or other form of packing e placed
in a groove or channel in the sides of the said bar as shewn in the drawings. The
central wing 6 of the glazing bar is bent over upon the glass for the purpose of
keeping it down, whilst the lower wings d of the glazing bar are bent under the
astragal for the purpose of making it secure thereto.
The channels on each side of the central projection a is utilized for conveying
away water or condensed moisture. The part just described may be hinged at the
rear end D for the purpose of being opened and closed after the manner of an
ordinary skylight or window.
The astragal A rests upon an adjoining glazing bar B'also attached to an astragalAL
and the glazing bars B are indented as shewn at E in Fig. 3 to permit the sheets
of glass C to overlap each other without uneven ridges.
Our improved glazing bar can be used for right and left hand sides of the glass, I
and in order to prevent the sheets of glass from slipping downwards, we fix a shoe
or clip as shewn at F in Fig. 3.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
Firstly. The combination of the glazing bar B with an astragal A in the manner
shewn, and adapting same to be used for glazing opening skylights, or other form
of windows, as shewn and described.
Secondly. The formation of indents in the glazing bar as shewn at E to permit
sheets of class to overlon seah athan
