PROVISIONAL SPECIFICATION.
Improved Bar for Carrying and Holding Sheets of Glass in Roof
Glazing or Skylights.
HENRY WILLIAMS BRADDOCK, Architect 6 Gapp Road, Wimbledon Surrey,
do hereby declare the nature of this invention to be as follows:-
A wrot iron or steel rolled bar section having well balanced flanges, and web.
therefore capable of carrying longest distances required with a minimum weight of
metal or sectional area.
To be entirely cased with lead, or other metal, capable of being made by bending
and doubling from the sheet metal or with a minimum amount of the usual expensive
process of drawing from the solid.
To be of such a section and arrangement that the cap, or casing, to the upper
flange may be easily renewed in case of deteriation, at a small cost and without
disturbing the glass or the remaining portion of the bar.
The casing to the lower flange may be made with or without the internal gutter,
generally called the condensed moisture gutter, or it may be made with a metal lip
to underside of glass.
Again, the casing to the lower flange together with the seats upon which the
glass is supported and which also form the main gutter, may be made from the
sheet metal by bending, doubling or rolling, or it may be drawn from the solid
metal.
Again, if the lip to the underside of the glass, or the condensed moisture gutter
be used, the casing to the lower flange, of which they would form a part, may be
made from the sheet metal by bending, doubling or rolling, or it may be drawn
from the solid metal.
The aforesaid cap or casing to the upper flange, of sheet metal lapping over and
holding the glass, is held in position by the projection of the upper flange on each
side of the web and by the edge of the glass.
Again, the aforesaid cap or casing to the upper flange may be held in position
by means of clips of copper, or other metal, placed at convenient distances apart
and fixed by pressure.
The casing to the lower flange may also be held in position by means of clips as
before described.
In the drawing A. shows the bar without either the metal lip to the underside
of the glass or the internal or condensed moisture gutter. B. shows the bar having
the metal lip to the underside of the glass. C. shows the bar having the internal
or condensed moisture gutter. D. shows the clip to the upper flange. E. shows
the clip to the lower flange. a. is the upper flange. b. the lower flange. c. the
web. d. is the cap or casing to the upper flange. e. is the casing to the lower
flange. f. is the internal or condensed moisture gutter. g. is the metal lip to the
underside of the glass. h. is the seat to support the glass. i. is the main gutter,
and j. is the glass.

I HENRY WILLIAMS BRADDOCK 6 Gapp Road Wimbledon Surrey, Architect
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 :-
A wrot iron or steel rolled bar section having well balanced flanges and web,
therefore capable of carrying longest distances required with a minimum weight of
metal or sectional area.
To be entirely cased with lead or other metal in two pieces, one to each flange,
of such an arrangement as will allow of the renewal, in case of deterioration, of the
cap or outer casing, to the upper flange of the bar, at a small cost and without
disturbing the remaining portion of the bar.
The aforesaid cap or casing to the upper flange of the bar, lapping over and
holding the glass, is held in position by the projection of the upper flange on each
side of the web and by the edge of the glass itself, preventing side movement of
the glass without interfering with its free expansion and contraction.
In the drawing a. is the upper flange. b. the lower flange. c. the web. d. is the
cap or casing to the upper flange. e. is the casing to the lower flange. i. is the
gutter and j. is the glass.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is
1. The form of section of the wrot iron or steel rolled bar, with flanges having
equality of sectional area, in its application to this purpose.
2. The manner of securing the soft metal cap, which folds over and holds the
gluss, by means of projections of the upper flange of the rolled bar on each side of
the web and the edges of the glass itself.
Dated this 9th dow of December 1800
