PROVISIONAL SPECIFICATION.
Improvements in the Mode of and Means for Glazing Roofs and
Skylights.
1, GEORGE MARTIN of 61 Brook Street, Smethwick, in the County of Stafford,.
Zinc Worker, do hereby declare the nature of my said invention to be as
follows
:-
My invention has for its object improvements in the mode of & means for
glazing roofs & skylights which I accomplish in a simple cheap & effective manner
so as to be thoroughly waterproof & with means for collecting the condensed
moisture.
In carrying my invention into effect I provide an iron glazing bar of anchor
shaped cross section which I fix to the purlins or other supports & along the
length of this I put a zinc cap which fits the top of the bar & which is bent out
some distance down the bar at each side to form a flange upon which the glass
rests the flange being bent up to form a gutter for any escaped water & then
under again in a downward direction until its edge rests against the sides of the
bar in the form of a strut or support to the flange at the same time allowing the-
flange to give sufficiently for any expansion or contraction which may occur.
The bottom portion of the bar forms a gutter for collecting the condensed
moisture which is conveyed into by the strut part of the zinc.
After this cap &
glass is in position an outer zinc cap which is made to fit on the under one & is
provided with the curved flanges on each side having their edges tightly sprung-
against the glass by reason of this outer cap being screwed down tightly through
the under cap into the iron bar which is provided at intervals with tapped holes
to receive the screws. Leather washers are provided under the heads of the
screws to prevent any leakage of the water through the screw holes in the zinc.

I, GEORGE MARTIN of 61 Brook Street Smethwick in the County of Stafford
Zinc Worker do hereby declare the nature of my said invention and in what manner
the same is to be performed to be particularly described & ascertained in and by
the following statement :-
My invention has for its object improvements in the mode of and means for
glazing roofs and skylights which I accomplish in a simple cheap and effective
manner so as to be thoroughly waterproof and with means for collecting the
condensed moisture.
In carrying my invention into effect I provide an iron glazing bar of anchor

length of this I put a zinc cap which fits the top of the bar and which is bent out
some distance down the bar at each side to form a flange upon which the glass
rests the flange being bent, up to form a gutter for any escaped water and then
under again in a downward direction until its edge rests against the side of the
bar in the form of a strut or support to the flange at the same time allowing the
flange to give sufficiently for any expansion or contraction which may occur..

page_text: The bottom portion of the bar forms a gutter for collecting the condensed moisture
which is conveyed into it by the strut part of the zinc. After this cap and glass
is in position an outer zinc cap which is made to fit on the under one and is
provided with curved flanges on each side having their edges tightly sprung
against the glass by reason of this outer cap being screwed down tightly through
the under cap into the iron bar which is provided at intervals with tapped holes to
receive the screws. Leather washers are provided under the heads of the screws
to prevent any leakage of the water through the screw holes in the zinc.
In order that my invention may be clearly understood and more easily carried
into practice I have appended hereunto a sheet of drawings upon which I have
fully illustrated the nature of my said improvements.
Figure 1. is a sectional view of my improved glazing.
I provide the iron glazing bar A which is fixed to the purlins or other supports
and along the length of this I place the zinc cap B, which fits the top of the
bar A and is bent out at to form a flange for the glass D to rest upon and
which also forms a gutter at 6 to collect any escaped water afterwards being
bent down at which forms a strut or support to the flange at the same time
allowing the flange to give in case of expansion or contraction. The bottom
portion a of the bar A forms a gutter for collecting the condensed moisture which
is conveyed into by the strut 63. The outer zinc cap E is provided to cover the
under one and is provided with the curved flanges e on each side having their
edges tightly sprung against the glass D by reason of this outer cap E being
screwed down through the under cap B into the bar A by the screws e³.
Leather washers are provided under the heads of the screws e¹ to prevent any
leakage of the water through the screw holes.
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 :-
:-
The improvements in the mode of and means for glazing roofs and skylights
substantially as and for the purpose herein set forth and shown upon the accom-
panying drawings.
