Improvements in Glazed Structures.
I, ARTHUR EDGCUMBE RENDLE, residing at No. 532 Walnut Street, Philadelphia,
Pennsylvania, United States of America, Engineer do hereby declare the nature of
this invention to be as follows:-
This invention has for its object to firmly and securely connect and support the
panes of glass in a glazed structure and to provide improved means for draining the
water of condensation which accumulates on the inner surface of the glass and that
which finds its way through the joints of the panes and their supports.
I provide a series of inclined troughs or astragals, and a series of cross troughs,
constructed and arranged to connect and support the panes of glass at their edges,
and to receive and carry off all the water accumulating upon the panes.
The inclined troughs or astragals are arranged equal distances apart, and extend
from the bottom to the top of the inclined roof, and the cross troughs are made in.
sections and arranged at right angles to the astragals. The inclined troughs may
be rectangular in cross section and they support on the upper ends of their sides,
panes of glass which are symmetrically arranged side by side in the same plane
without overlapping edges.
The longitudinal edges of the panes are separated and through the intervals
extend bolts having at their lower ends eyes through which extend horizontal
bolts secured to the troughs or astragals. The eye-bolts extend through caps or
covering strips, and their upper ends are screw-threaded and provided with
tightening nuts.
Caps or covering strips extend from end to end of the troughs, and completely
cover the openings between the panes.
I may employ a flat metal strip covered with lead, copper or other non-corrosive
material, or I may employ a curved sheet metal yielding cap.
In either case,
the construction is such that the glass, is firmly supported, securely held in place
and provided with means for draining off water which may leak in through the
joints.
The cross troughs are made in short sections and supported in recesses in the
troughs or astragals. Each cross trough is preferably made of sheet metal. One
side is slightly shorter than the other side, so as to leave a small space between its
upper edge and the glass and allow water of condensation to pass into the main
gutter or channel of the trough. The other side is prolonged by being bent
inwardly and downwardly, then upwardly and formed with a ledge. It is then
bent upwardly and laterally to form a support for the adjacent edges of the panes
of glass. The upper panes rest on the ledges, and the lower panes on the edges of
the sides of the troughs. The construction such as to form a small gutter, which
may be perforated and through which the water which finds its way into the joints
passes into the main trough, gutter or channel, and thence into the inclined troughs
or astragals.

Improvements in Glazed Structures.
I, ARTHUR EDGCUMBE RENDLE, residing at No.532 Walnut Street, Philadelphia,
Pennsylvania, United States of America, Engineer, 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 has for its object to firmly and securely connect and support the
panes of glass in a glazed structure and to provide improved means for draining the
water of condensation which accumulates on the inner surface of the glass and that
which finds its way through the joints of the panes and their supports.
I provide a series of inclined troughs or astragals, and a series of cross troughs,
constructed and arranged to connect and support the panes of glass at their edges,
and to receive and carry off all the water accumulating upon the panes.
The inclined troughs or astragals are arranged equal distances apart, and extend
from the bottom to the top of the inclined roof, and the cross troughs are made in
sections and arranged at right angles to the astragals. The inclined troughs may
be rectangular in cross section and they support on the upper ends of their sides,
panes of glass which are symmetrically arranged side by side in the same plane
without overlapping edges.
The longitudinal edges of the panes are separated and through the intervals
extend bolts having at their lower ends eyes through which extend horizontal bolts
secured to the troughs or astragals. The eye-bolts extend through caps or
covering strips, and their upper ends are screw-threaded and provided with
tightening nuts.
Caps or covering strips extend from end to end of the troughs, and completely
cover the openings between the panes.
I may employ a flat metal strip covered with lead, copper or other non-corrosivė
material, or I may employ a curved sheet metal yielding cap.
In either case,
the construction is such that the glass is firmly supported, securely held in place
and provided with means for draining off water which may leak in through the
joints.
The cross troughs are made in short sections and supported in recesses in the
troughs or astragals. Each cross trough is preferably made of sheet metal. One
side is slightly shorter than the other side, so as to leave a small space between its
upper edge and the glass and allow water of condensation to pass into the main
gutter or channel of the trough. The other side is prolonged by being bent
inwardly and downwardly, then upwardly and formed with a ledge. It is then
bent upwardly and laterally to form a support for the adjacent edges of the panes
of glass. The upper panes rest on the ledges, and the lower panes on the edges of
the sides of the troughs. The construction is such as to form a small gutter, which
may be perforated and through which the water which finds its way into the joints
passes into the main trough, gutter or channel, and thence into the inclined troughs
or astragals.
In order that my invention may be more fully understood, reference is made to
the accompanying drawings, in which--
Figure 1 is a view of a portion of a glass roof constructed in accordance with my
invention;
Fig. 2 is a detail view in section, showing particularly the manner of supporting
the glass by cross troughs;
Fig. 3 is a detail view in sections, on the line 3-3 of Fig. 2, showing
particularly the manner of supporting the glass by the inclined troughs or
astragals;

page_text: Fig. 4 is a section on the line 4-4 of Fig. 2: and
Fig. 5 is a perspective view, showing the manner of supporting the cross troughs
by the inclined troughs.
The inclined troughs or astragals A, are arranged equal distances apart, and
extend from the bottom to the top of the inclined roof, and the cross troughs B,
which are made in sections, are arranged at right-angles to the troughs A, as
shown in Fig. 1. The inclined troughs A, may be rectangular in cross section, or
of other suitable shape, and they support on the upper ends of their sides a, the
panes of glass C, which are symmetrically arranged side by side in the same plane,
without overlapping edges, as clearly illustrated in the drawings. The longitudinal
edges of the panes are separated, as indicated, and through the intervals extend
bolts D, having at their lower ends eyes d, through which extend bolts d', secured
to the trough A. The bolts d¹, are preferably square in cross section, as shown,
but they may be round. The eye-bolts B, extend through caps or covering
strips E, and their upper ends are screw-threaded and provided with tightening-
nuts d². Caps or covering strips E, extend from end to end of the troughs, and
completely cover the openings between the panes; in fact, overlapping their edges
to a considerable extent, so as to provide as far as possible a water-tight closure.
I may employ a flat metal strip covered with lead, copper or other like non-
corrosive material, e, as shown at the left-hand side of Fig. 3, or I may employ_n
curved sheet metal yielding cap, as indicated at the right-hand side of Fig. 3. In
either case, the construction is such that the glass is firmly supported, securely held.
in place and provided with means for draining off water which may leak in through
the joints.
The troughs A, may be supported on the frame of the roof, in any desired way.
At the right-hand side of Fig. 3, I have shown brackets F, which are adapted to
be secured to the purlins. In order to support the panes at their upper and lower
edges, and to convey off water which may leak in through the joints, or accumulate
by condensation on the panes, I employ cross troughs B, which are preferably
made in short sections, as shown in Fig. 1, and supported in recesses a', in the
troughs or astragals A, as shown in Fig. 5. Each cross trough is preferably-made
of sheet metal having a bottom g, and sides y', g³. The side y², is slightly shorter
than the side gl, so as to leave a small space between its upper edge and the glass,
to allow water of condensation to pass into the main gutter or channel, of the
trough. The side g¹, is prolonged by being bent inwardly and downwardly, then
upwardly and formed with a ledge gs. It is then bent upwardly and laterally to
form a support for the adjacent edges of the panes. The upper panes rest on the
ledges g³, the lower ones on the edge, at the top of the side g. This pane also
is arranged under the lateral projection . The construction is such as to form a
small gutter g, having perforations 9', through which the water which finds its
way in at the joints passes into the main gutter or channel .r, and thence into the
inclined troughs A. As before stated, the water of condensation passes from the
under sides of the panes above the sides g³, of the trough at y, into the gutter or
channel x.
It will be observed by inspection of Fig. 1, that the cross troughs are arranged
to empty into the inclined troughs and that provision is made for draining off all
water that may tend to accumulate either on the upper or lower surface of
the roof.
A roof constructed as shown and described, is strong and durable, may be easily
replaced, the panes of glass do not overlap, and the danger of destruction by wind
or other causes is reduced to a minimum.
And now having particularly described and ascertained the nature of this said
invention, and in what manner the same is to be performed, I declare that what I
claim is-
1. The combination of a series of inclined troughs or astragals, having imperforate
bottoms, panes of glass supported on the upper edges of the sides of the troughs,

page_text: caps or strips bearing on the edges of the panes, eye-bolts connected with the strips
or caps, and extending downwardly therefrom, and cross-bolts d', passing through
the eyes in the eye-bolts and attached to the troughs above their lower ends or
bottoms, substantially as described.
2. The combination with the inclined troughs or astragals having the caps or
covers, of a series of cross troughs resting in recesses in the astragals, each of said
cross troughs having a main gutter or channel, and a supplemental. gutter 96, a
supporting ledge g³ for a pane of glass, and a support for another pane of glass in
line with the supporting ledge g³, and formed integrally with one side of the main
trongh:
43. The herein described cross trough formed of a single piece of sheet metal
having the bottom and sides y, g', g², a supporting ledge g³, for a pane of glass
arranged between the two sides of the main gutter or channel, and a support for
another pane of glass at the top of one of the sides of the main trough and in line
with the supporting ledge g³, and a gutter formed from that part of the sheet of
metal which connects the ledge g³ with the upper end of the side g¹.
4. The combination with a series of inclined troughs or astragals, of a series of
panes of glass supported thereon, the caps or strips resting on the glass, a series of
eye-bolts secured to the caps or strips, a series of cross bolts passing through the
eyes in the eye-bolts and secured to the troughs, and a series of cross troughs made
in short lengths each adapted to extend from one astragal to the next astragal at
its side, and opening into it, each cross trough being formed of sheet metal having
a main gutter or channel a, a side g², terminating beneath the panes of glass over
it to leave the opening y, for the purpose specified, a supporting ledge 93, arranged
between the two sides of the trough, a support on the upper end of the side g', for
a pane of glass, and a gutter arranged between this support and the supporting
ledge, the organization being such that the panes of glass throughout the structure
are all arranged on a level or with butt joints instead of overlapping joints, and
with gutters or troughs provided to carry off water which either leaks through
from the outside or which accumulates on the inside of the panes on both sides of
all joints.
5. The herein described cross trough having the main gutter or channel, the
side piece g', for supporting a pane of glass, the small gutter g, emptying into the
main gutter, the ledge g³ for supporting a pane of glass, and the projection g'; for
the purpose specified.:
6. The glazed structure, substantially such as described and shown in Figures 1
and 2 of the drawings.
