Improvements in and relating to the Glazing of Roofs and other
Structures.
I, CHARLES CORDON, of York Villa, Harpenden, in the County of Herts, Plumber
and Builder, do hereby declare the nature of this invention to be as follows:-
This invention relates to an improved system of, or improvements in and
relating to the glazing of the roofs of railway stations and buildings, or other
buildings and structures.
the
In carrying out my improvements the sheets of glass which may conveniently
be "rough cast," or "rolled plate" are laid on the sash bars, rafters or frames,
at sufficient distances apart to admit of the screws, to hold the fixing strips
or capping in place, passing down between the adjacent edges of
sheets into the sash bars or roofing bars below. These strips or caps, which
may be made of zinc, copper or galvanized iron or other suitable metal, are
formed of an arched section with cross tie pieces, across the interior of the
arch or other form, as may be found convenient. The arch strips are made of
such a curve as to readily throw off the water falling on them and the bases
of the arches where they rest in contact with the glass are disposed well away
from the junction of the sheets of glass. The sections of stripping-say, in
three or four feet lengths-are made to overlap each other beginning at the
lowest as also are the sheets of glass. In the case of skylights and other
structures the uppermost sections of these strips are formed at their ends, so
that the slates, or roofing material of such kind, may overlay the glass and the.
strips; and, to facilitate this, these strips for the distance of such overlay may
be formed of a flat inverted trough section. At, or towards their lower edges
these strips are formed deeper by about the extent equal to the thickness of
the sheets of glass, so that such deeper parts may form stops to prevent the
slipping down of the sheets of glass, or this may be attained by turned down
ends or stops formed for the like object on the ends of such strips or caps.
These strips or caps are held in place by means of screws, as referred to,
passing through the strips at the tops of the arches, and down between the edges
of the sheets and into the bars or rafters.
The screws are formed preferably with threads only sufficiently long to take
good hold of the bars and the heads are formed countersunk, or mushroomed
on their under sides where they come in contact with the strips. By these
means the "mushroom " recess receives within it and around the screw, the
apturned edge of the hole in the metal of the strip it pins down, said "burr"
r upturned edge being produced in the stamping:
Where the sheets are laid so as to rest flush against the side frames in the
tructure, any suitable flashing may be employed to complete making of a
Feather tight joint and soakers or soaking strips may be applied at the meetings
f the glass and side frame.
By the construction indicated the employment and cost of lead back gutters
nd aprons at the junctions of the glazing or glazed and solid structures is
voided.

page_text: The glass sheets are in some cases formed with their upper surfaces adjacent
to their side edges slightly raised--say, to the extent of a tenth of an inch-and
by these means the effect of a shallow trough is attained at each side of each
sheet of glass between the contacting edge of the sheet metal stripping or cap-
ping thereon, and such raised edging, so that should any water find its way
under the stripping or capping it will find a gutter to receive and carry it away
to outside again at foot of the series of overlayed sheets. Each sheet, to facilitate
closeness of fit, may be formed at its lower under surface for the distance equal
to the overlap with recesses equal to that extent of the ridges or raised edgings
it covers in laying over the under sheet.
These sheets of glass with their ridges or slightly side surfaces may be pro-
duced in a continuous sheet the ridges in pairs adjacent or connected, and they
may be separated into say--15 inch or other width of strips by cutting or
dividing them along a line between, or through the ridge, or extra thickness
leaving the side raised parts as described.

Improvements in and relating to the Glazing of Roofs and other
Structures.
I, CHARLES CORDON, of York Villa, Harpenden, in the County of Herts, Plumber
and Builder, 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:-
This invention relates to an improved system of, or improvements in and
relating to the glazing of the roofs of railway stations and buildings or other
buildings and structures.
Fig. 1 shows a plan view of a small construction of roof light designed to
illustrate my invention.
.
Fig. 2 is an underside view of the same.
Fig. 3 is a similar view to Fig. 1 but with the cappings and other parts
removed, in order the better to illustrate the arrangement of the panes of glass
on their supports.
Fig. 4 shows a horizontal section taken on the line E, F of Fig. 2.
Fig. 5 shows to a small scale a general view in plan of a piece of glass roof
construction according to the invention.
Fig. 6 shows a modification in the means of supporting and attaching the
glass to the roll capping to prevent the roll from being lifted in event of
expansion, in light structures in which bars intermediate of the main side
frames are dispensed with and the rolled cappings are carried from purline to
purline.
Fig. 7 shows a plan view of one of the roll cappings employed as the upper-
most of a series, and
Fig. 8.is a section thereof on the line I,J of Fig. 7.
Fig. 9 is section on the line G, H of Fig. 7.
Fig. 10 shows by plan view, and
Fig. 11 by section one of the intermediate roll caps.
Fig. 12 shows by plan view, and
Fig. 13 by longitudinal section one of the bottom caps.

page_text: Fig. 14 shows a sectional view taken on the line A, B of Fig. 1.
Fig. 15 shows a like view, but taken on the line C, D of Fig. 1.
Fig. 16 shows a plan view of portions of panes of glass of the shape adapted
to carry out this invention, and
Fig. 17 shows a transverse section of the same.
Fig. 18 shows a transverse section of the capping, applied on glass of the
shape shown in Fig. 17, with rolled iron shaped bar support.
Fig. 19 shows the like parts to Fig. 18 with wooden bars in place of iron and
Fig. 20 shows like parts but with combined wood and T iron supporting bars.
Fig. 21 shows one of the tee ended supports and screw nuts for use in sup-
porting the panes of glass intermediate of the purlines as shown in Fig. 6.
In carrying out my improvements the sheets of glass a, a which may con-
veniently be rough cast," or rolled plate," are laid on the sash-bars, rafters,
or frames b, 61, or 62, at sufficient distances apart to admit of the screws c, to
hold the fixing strips, or cappings, d, d¹ or d² in place, passing down between
the adjacent edges of the sheets of glass a into the sash bars, or roofing bars b, b¹
or 62 below.
"
These strips, or caps d, d', or d² which may be made of zinc, copper, gal-
vanised iron, or other suitable metal are formed of an arched section with cross
tie pieces d across the interior of the arch, or other form of such caps, as may
be found convenient.
The arch strips d, d¹, d² are made of such a curve as to readily throw off the
water falling on them and the bases of the arches d' where they rest in contact
with the glass are disposed well away from the junction of the sheet of glass a.
The sections of stripping d, d¹ or d say, in three or four feet lengths are made
to overlap each other begining at the lowest sets -as d2 as also are the sheets
of glass. In the case of skylights as Figs. 1 and 2 and other structures the
uppermost sections of these strips are formed at their ends, so that the slates,
or roofing material of such kind may overlay the glass panes a as at a¹ and
the strips; and, to facilitate this, these strips d, for the distance of such overlay
may be formed of a flat inverted trough section as at . At or towards their
lower edges these strips are formed deeper by about the extent equal to the
thickness of the sheets of glass a so that such deeper parts may form stops
to prevent the slipping down of the sheets of glass, or this may be attained
by turned down ends or stops formed for the like object on the ends of such
strips or caps d, d¹, d².
These strips or caps d, d', d², are held in place by means of screws c passed
into holes and through the strips d, d, or at the tops of the arches, and
down between the edges of the sheets a and into the bars, rafters or purlines.
The screws c are formed preferably with threads only sufficiently long to
"mush-
take good hold of the bars and the heads are formed countersunk, or
roomed on their under sides where they come in contact with the strips.
A modified form of screw 2, see Figs. 6 and 21, may be employed to preserve
proper close relationship between the sheets of glass and the side bars. The
tee ends of these screws (Fig. 21) are passed between adjacent edges of two
sheets of glass--the stem of the screw being engaged in the rolled capping and
the tee is given a quarter turn bringing the arms under the glass. The
nut which is mushroomed serves to tighten up the parts and to support the
glass from the rolls or capping d, d¹, d².
"
By these means the mushroom recess receives within it and around the
screw, the upturned edge of the hole in the metal of the strip it pins down,
said "burr" or upturned edge being produced in the stamping.
Where the sheets are laid so as to rest flush against the side frames in the
structure, any suitable flashing may be employed to complete making of a
5 weather tight joint and a convenient or usual form of soakers or soaking strips
may be applied at the meetings of the glass and side frame.
By the construction indicated the employment and cost of lead back gutters

page_text: and aprons at the junctions of the glazing or glazed and solid structures is
avoided.
The glass sheets a are formed with their upper surfaces a² adjacent to their
side edges slightly raised, say to the extent of a tenth of an inch-and by
these means the effect of a shallow trough is attained at each side of each sheet
of glass between the contacting edge of the sheet metal stripping or capping d, d
or 2, thereon, and such raised edging a², so that should any water find its
way under the stripping or capping it will find a gutter to receive and carry
it away to the outside again at foot of the series of overlayed sheets.
Each sheet, to facilitate closeness of fit may be cut or formed at its lower
under surface as at a,³, for the distance equal to the overlap with recesses
equal to that extent of the ridges or raised edgings it covers in laying over
the under sheet, see Fig. 17.
These sheets of glass with their ridges or slightly raised side surfaces may
be produced in a continuous sheet the ridges in pairs adjacent or connected,
and they may be separated into say-15 to 18 inch or other width of strips by
cutting or dividing them along a line between, or through the ridge, or extra
thickness leaving the side raised parts as described.
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 and use of glass in sheets with raised ribs thereon in
combination with means for securing the same to the ribs, bars, rafters or
purlines or the like, substantially as described and shown by the drawings.
2. The construction and use of the retaining cappings or roll coverings for
the meeting edges of sheets of glass, and adapted to be screwed or similarly
fastened to the underlying ribs, bars, rafters, purlines or the like, substantially
as described and shown by the drawings.
3. The method of constructing and fitting the sheets of glass in series as set
forth particularly with reference to Figs. 16 and 17.
4. The system of glazing for roofs and such like uses, substantially as described
and shown by the drawings:
