Improvements in Glazing for Roofs and the like Structural Work.
WILLIAM LAWSON, 15, Posterngate, Hull, Plumber, do hereby declare the
nature of this invention to be as follows:-
This invention relates to the manner of securing the metal covering or plates
to the metal bars as used in glazing for various kinds of roofs, skylights and the
like construction.
In carrying my invention into effect, I provide a glazing bar, preferably of
1- iron. I also provide a metal cover, preferably of lead or copper, to receive
the glass, the same being continued over the web of the glazing bar. I also
provide another metal cover, to cover the top edges of the glass, the same also
being continued over the web of the glazing bar.
By this construction the edge of the glass is fitted between the two ledges
of the said covers, which run along the glazing bar.
And in order to secure the said covers to the glazing bar, a hole is made
through the first mentioned cover, and also through the web of the glazing
bar, through which a tubular rivet preferably of lead, is secured, the two ends
of the said rivet being formed into a flange. When the second mentioned cover
is placed in position, a hole is made through the same opposite to the hole of
the tubular rivet, through which another rivet, preferably similar to the first
mentioned rivet, is secured.
The object of my invention is to prevent any water getting through the joint
where fastenings are used for securing the metal covers to the metal bars.
Dated this Twenty-sixth day of August 1899.

Improvements in Glazing for Roofs and the like Structural Work.
WILLIAM LAWSON, of 15, Posterngate, Hull, in the County of York, Plumber,
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:-
-
My invention relates to the manner of securing coverings or plates to the
bars as used in glazing for various kinds of roofs skylights and the like struc-
tural work.
The object of my invention may be accomplished by using a wood or metal
glazing bar, a supporting or glazing cover preferably of a metallic substance
LD 071

page_text: shaped so as to receive the glass, and a cover or capping preferably of a metallic
substance shaped
so as to cover the top edges of the glass. And in order to
secure the said covers, a hole is made through both the supporting or glazing
cover and the glazing bar through which is secured a tubular rivet preferably
of lead and with the ends open and flanged. A hole is also made through the
cover or capping opposite to the hole of the tubular rivet through which is
secured a key bolt or a smaller rivet preferably of lead and with flanged ends.
But in order that my invention may be clearly understood I annex herewith
one sheet of drawings in which Figures 1 and 2 each represent in cross section
a convenient modification.
A-represents a form of glazing bar,
B represents a supporting or glazing cover,
C-represents a tubular rivet as fixed before the cover or capping is in posi-
tion,
D-represents a cover or capping, and
E represents a rivet as fixed after the cover or capping is in position.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is
1 The construction in which covers or cappings are secured to glazing bars
by a tubular rivet with open ends in combination with a smaller rivet or bolt
all arranged substantially as hereinbefore described.
