PROVISIONAL SPECIFICATION.
An Improved Method of and' Means for Glazing Roofs, Lights, and
the like, especially applicable to Vertical Glazing.
We, ERNEST ALLAN Blake, Ironworker, George Pullen Ironworker and
HOWARD HENRY BURLEIGH, Ironworker, trading as Allan Brothers, of 18 Garden
Row, Stockwell in the County of Surrey, do hereby declare the nature of this.
invention to be as follows:-
Our invention relates to an improved method of glazing and to means for
carrying the same into effect, the object thereof being to provide an efficient.
jointing which is weatherproof, and non corrosive, and allows of a certain degree of
expansion and contraction due to the various materials employed, relatively to the
variation of temperature.
In carrying our invention into effect, we employ a trough or channel bar of steel,
or other metal preferably covered with lead or other anti corrosive substance, by
chemical or mechanical means. Said channel bar is attached by screws or the
like to the framework of the light or roof to which it is to be adapted, by means of
screws or equivalent fastenings.
The plates, panes, or sheets of glass are laid in the usual manner so that the
vertical or angular edges rest upon the edges of said channel bar, a space being
maintained between them. An inverted tee bar preferably covered with lead or
other non-corrosive metal or material is placed so that the transverse web
covers and overlaps the edges of the plates of glass. Set screws or bolts are
passed through holes in the tee bar, screwing into the channel bar, and retaining
the glass in position. The central web of the tee bar is cut away to allow of
the free adjustment of the set screws or equivalents, so as not to impose an
undue strain upon the glass. The channel bar is attached to the framework by
screws as aforesaid, and is secured at the lower end by a shield and clip which
prevents the glass from slipping and also precludes the entry of dust or dirt,
while any water that may accumulate in said channel may be drained off by
means of a suitable pipe or pipes, or is directed away from the building by the
inclination of the shield.
The set screws and attachment screws or their equivalents may be made of
gun metal or other non-corrodible substance, and the surfaces in contact, and
subject to atmospheric 'influence, may be covered or coated with any metal
material or substance that is capable of resisting said influence and promoting
the durability and efficiency of the structure.

COMPLETE SPECIFICATION.
An Improved Method of and Means for Glazing Roofs, Lights, and
the like, especially applicable to Vertical Glazing.
We ERNEST ALLAN BLAKE, Ironworker, GEORGE PULLEN Ironworker, and
HOWARD HENRY BURLEIGH Ironworker, trading as Allan Brothers, of 18 Garden
Row Stockwell in the County of Surrey, 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 relates to an improved method of glazing and to means for

page_text: carrying the same into effect, the object thereof being to provide an efficient
jointing which is weather proof, and non corrosive, and allows of a certain degree
of expansion and contraction due to the various materials employed, relatively to
the variation of temperature.
In order to fully describe our said invention, we have appended the accompanying
sheet of drawings in which
Fig. 1 is a cross section of the trough or channel bar to be hereinafter more fully
described, shewing the method employed for retaining the sheets or panes of
glass.
Fig. 2 is a longitudinal section of same shewing method of fixing the channel
bars to the framework of the light or roof.
Fig. 3 is an external view of our improved method, shewing the clip or shield
used to prevent the glass slipping, and also to prevent the accumulation of dust or
the like in the channel bar afore mentioned.
In carrying out our invention, we employ a trough or channel bar of steel, or
other metal A. preferably covered with lead or other anticorrosive metal or
substance, by chemical or mechanical means. Said channel bar A is attached
by screws or the like to the framework of the light or roof to which it is to be
adapted as shewn at a Fig. 2. The plates, panes or sheets of glass C are laid in
the usual manner so that the vertical or angular edges rest upon the edges of said
channel bar, a space being maintained between them as shewn in Fig. 1. An
inverted tee bar D preferably coated with lead or other non-corrosive metal or
material is placed so that the transverse web covers and overlaps the edges of the
plates of glass C. Set screws d are passed through holes in the tee bar, screwing
into the channel bar and retaining the glass in position. The central web of the
tee bar D is cut away as shewn in Fig. 2 to allow of the free adjustment of the set
screws, bolts or equivalents, so as not to impose an undue strain upon the glass.
The channel bar is attached to the framework B by screws a as aforesaid, and has
secured at its lower end a clip or shield E which prevents the glass from slipping,
and also precludes the entry of dust or dirt, while any water that may accumulate
in said channel may be drained off by means of a suitable pipe or pipes, or is
directed away from the building by the inclination of the shield E Fig. 3. The
set screws and attachment screws or their equivalents may be made of gunmetal or
other non corrosive substance, and the surfaces in contact, and subject to atmo-
spheric influence, may be covered with, or coated with any metal,. material or
substance that is capable of resisting said influence and promoting the durability
and efficiency of the structure.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we, declare that
what we claim is:
In glazing, the employment of channel bars, shields and plates in combination
with glass or other like substance substantially as herein described and shown.
