Year: 1884

page_text: I THOMAS ROBERT SHELLEY of N° 40 William Edward Street Birmingham in
the County of Warwick Glazing Contractor do hereby declare the nature of the
said Invention for "IMPROVEMENTS IN GLAZING CONSERVATORIES Roof OF
RAILWAY STATIONS, ARCADES AND OTHER BUILDINGS AND STRUCTURES" to be as
follows:-
My Invention has for its objects to secure the glass very efficiently to the
supporting bars of the roof building or structure and to provide means for the
carrying away of any water which may escape between the joints of the glass.
I effect these objects by constructing the glazing bars and appliances connected
therewith in the manner hereinafter described.
I form on each side of the glazing bar a longitudinal wing or rib upon which
ribs the edges of the glass are supported and at the bottom of the bar I forin an
expanded part the sides of which constitute other supports. On each side of the
bar a sheet metal trough or hollow jaw is arranged and fixed. These troughs or
jaws act as gutters for carrying off any rain or moisture which may escape through
the joints and also serve for supporting the glass. These sheet metal troughs and
supporting jaws may either be made in two pieces or in one piece. When made in
two pieces each trough is furnished on its inner side with a groove for embracing
the wing or rib on the bar the bottom of each trough piece resting on the
expanded seat or support at the bottom of the bar. The metal of the trough is
prolonged upwards beyond the embracing groove described to a height a little
above the upper surface of the glass. The top of the outer side of the trough or
jaw is slightly expanded outwards and is carried a little above the level of the
wing or rib on the side of the bar. The glass besides being supported on the wing
or rib on the glazing bar is also supported on the yielding side described of the
trough or jaw the weight or pressure of the glass causing the said yielding side to
be slightly flattened. By the clasticity of this supporting jaw a very tight junction
is effected between it and the glass. Should any wet escape between the vertical
edge of the glass and the prolonged inner side of the trough or jaw the said wet
passes into the trough and is conveyed away.
When the sheet metal troughs and supporting jaws are made in one piece they
are secured to the glazing bar by screwing the said bar to a separate trough casing

screwing of the glazing bar to the bottom supporting casing when the sheet metal
jaws are made in one piece may be dispensed with by expanding the bottom of the
bar at intervals and engaging the casing with the said expanded parts of the bar
by a sliding end motion. The sheet metal capping which is placed over the top
of the glazing bar for holding down the glass is securel to the said bar at the
required intervals in the following ways. Hollow screws with heads at one end
are passed through the capping and bar from one side and headed screw pins are
passed through the capping and bar from the other side and screwed into the
hollow screws.
Or a plain pin may be used having a neck or contraction near
each end for receiving a fastening fork or cotter. Opposite sides of the web where
the pin is inserted may be reduced in thickness to permit of the fastening forks or
cotters obtaining a better hold against the yielding capping than they would if the
capping was supported by a solid part of the web. Snugs are secured to the
glazing bar at each end to attach the bar to the supporting bearers the said snugs
also serving to receive the sheet metal jaws hereinbefore described. Projections are
also cast on the glazing bar or snugs to prevent the glass sliding down.
The sheet metal troughs and supporting jaws may either be made separately as
hereinbefore described or they may be made in one piece by the drawing process
and bent or doubled over the top of the bar.
Although I have only described my Invention with respect to roofing yet my
said Invention may also be applied to the vertical sides of conservatories and other
buildings and structures.

page_text: I THOMAS ROBERT SHELLEY of N° 40 William Edward Street Birmingham in
the County of Warwick Glazing Contractor do hereby declare the nature of my
Invention for "IMPROVEMENTS IN GLAZING CONSERVATORIES ROOFS OF RAILWAY
STATIONS, ARCADES AND OTHER BUILDINGS AND STRUCTURES" and in what
manner the same is to be performed to be particularly described and ascertained in
and by the following statement:—
My Invention has for its object to secure the glass very efficiently to the
supporting bars of the roof, building or structure and to provide means for the
carrying away of any water which may escape between the joints of the glass.
I effect these objects by constructing the glazing bars and appliances connected
therewith in the manner herein after described.
I form on each side of the glazing bar a longitudinal wing or rib upon which
ribs the edges of the glass are supported and at the bottom of the bar I form an
expanded part the sides of which constitute other supports. On each side of the
bar a sheet metal trough or hollow jaw is arranged and fixed. These troughs or
jaws act as gutters for carrying off any rain or moisture which may escape between
the joints and also serve for supporting the glass. These sheet metal troughs and
supporting jaws may either be made in two pieces or in one piece. When made
in two pieces each trough is furnished on its inner side with a groove for
embracing the wing or rib on the bar, the bottom of each trough piece resting on
the expanded seat or support at the bottom of the bar.
The metal of the trough is prolonged upwards beyond the embracing groove
described to a height a little above the upper surface of the glass. The top of the
outer side of the trough or jaw is slightly expanded outwards and is carried a
little above the level of the wing or rib on the side of the bar. The glass besides
being supported on the wing or rib on the glazing bar is also supported on the
yielding side described of the trough or jaw the weight or pressure of the glass
causing the said yielding side to be slightly flattened. By the elasticity of this
supporting jaw a very tight junction is effected between it and the glass. Should
any wet escape between the vertical edge of the glass and the prolonged inner side
of the trough or jaw the said wet passes into the trough and is conveyed away.
When the sheet metal troughs and supporting jaws are made in one piece they
are secured to the glazing bar by screwing the said bar to a separate trough casing
embracing and giving rigidity to the lower halves of the sheet metal jaws. Or the
screwing of the glazing bar to the bottom supporting casing when the sheet metal
jaws are made in one piece may be dispensed with by expanding the bottom of the
bar at intervals and engaging the casing with the said expanded parts of the bar
by a sliding end motion. The sheet metal capping which is placed over the top of
the glazing bar for holding down the glass is secured to the said bar at the
required intervals in the following ways. Hollow screws with heads at one end
are passed through the capping and bar from one side and headed screw pins are
passed through the capping and bar from the other side and screwed into the
hollow screws. Or a plain pin may be used having a neck or contraction near
each end for receiving a fastening fork or cotter. Opposite sides of the web where
the pin is inserted may be reduced in thickness to permit of the fastening forks or
cotters obtaining a better hold against the yielding capping than they would if the
capping was supported by a solid part of the web.
Snugs are secured to the glazing bar at each end to attach the bar to the
supporting bearers the said snugs also serving to receive the sheet metal jaws
herein before described,

page_text: Projections are also cast on the glazing bar or snugs to prevent the glass
sliding down.
The sheet metal troughs and supporting jaws may either be made separately
as herein before described or they may be made in one piece by the drawing
process and bent or doubled over the top of the bar.
Although I have only described my Invention with respect to roofing yet my
said Invention may also be applied to the vertical sides of conservatories and other
buildings and structures.
Figure 1 of the accompanying Drawings represents in cross section a glazing bar
and appliances constructed according to my Invention the sheet metal troughs and
supporting jaws being made of separate pieces.
a is the glazing bar having on each side a longitudinal wing or rib b on which
the edge of the glass c is supported and also having at its base an expanded seat d,
the sides of which constitute other supports; e, e are the metal troughs and hollow
jaws placed upon opposite sides of the glazing bar a the groove part of the trough
embracing the wing b on the bar and the bottom of each trough part resting on
the expanded seat d at the bottom of the bar. The trough parts of the combined
troughs and jaws e, e act as gutters for carrying off any rain which may escape
between the joints, and the jaws serve for supporting the glass c.
It will be seen
by an examination of the Drawing that the top of the inner side of each trough
or jaw e is slightly turned outwards and is carried a little above the level of the
wing b on the bar and the glass c besides being supported on the said wing b is
also supported on the yielding outer side of the trough or jaw e the weight or
pressure of the glass causing the said yielding side to be slightly depressed when
the glass is laid upon it.
This yielding jaw secures a very tight junction between it and the glass. It
will also be seen by an examination of Figure 1 that the metal of the trough is
prolonged upwards beyond the upper surface of the glass c so that should any wet
escape between the vertical edge of the glass and the said prolonged inner side of
the sheet metal trough the said wet passes into the trough and is conveyed away;
fis the sheet metal capping used for holding down the glass. The capping may
be held in its place by either of the several ways herein after described.
Figure 2 represents in cross section a modification of the arrangement Figure 1;
Figure 3 represents a side elevation of the glazing bar. In this arrangement the
seat or support d is extended outwards and curved upwards and is covered with
sheet metal by an end sliding motion. This covered bottom seat d besides
supporting the troughs and jaws e, e also serves to carry away any wet which
may run down the outer sides of the said jaws.
Figure 4 represents in cross section an arrangement of my Invention in which
the sheet metal trough and supporting jaws are made in one piece; Figure 5
represents a side elevation of the glazing bar. In this arrangement a separate
trough shaped casing g is made to embrace and give rigidity to the lower parts of
the sheet metal troughs and jaws e, e, the said casing g being fixed to the glazing
bar a by screws and screw nuts at the screws being cast in expanded parts i
made at intervals in the base of the glazing bar a. Or screws may be tapped
directly into the top of the bar instead of casting then in the bar as represented.
Or the casing g and the lower part of the supporting jaws e may have the form
represented in Figure 6 and the base of the glazing bar a have curved expansions /
made upon it at intervals or throughout its whole length. By engaging the
casing Figure 6 carrying the troughs and jaws e, e with the expansions
the bar a by a sliding end motion the several parts are connected together.
of
Or the supporting casing g when the troughs and jaws are made in one piece
may be omitted as represented in perspective in Figure 7. In this modification
the base of the troughs and supporting jaws have the general configuration of the
expanded bottom of the glazing bar a and the said troughs and jaws are fixed inii
their places on the base of the glazing bar by being engaged with the expanded
bottom part by an end sliding motion.

page_text: I will now describe the arrangements for securing the sheet metal capping f to
the glazing bar. In the vertical section Figure 8 a hollow screw m with a head
at one end is passed through the capping f and bar a from one side and a headed
screw pin n is passed from the other side of the capping and screwed into the
hollow screw m. Figure 9 represents the hollow screw and screw pin detached.
These hollow screws and screw pins are employed at the required intervals along
the capping f
Or the hollow screw m may be shortened so as to give it the form of a screw
cap as represented in cross section and side elevation in Figure 10 where the
screw pin passed fron one side of the capping f is marked p and the screw cap
screwed onto the projecting end of the screw pin pon the other side of the
capping is marked q.
Or instead of fixing the capping f by screw pins passing through the glazing bar
from side to side, the capping may be fixed by screws at the head of the glazing
bar as represented in Figures 2 and 3.
In this modification a series of screw pins at the required intervals is cast or
tapped in the top of the glazing bar a and after the capping has been put in its'
place, screw caps 8 are screwed upon the projecting ends of the screw pins > as
represented in Figure 2.
Figure 11 represents in vertical section my arrangement in which a fastening
fork or cotter is used for fixing the capping in conjunction with a plain pin;
Figures 12 and 13 represent the parts of the fastening separately; the same
arrangement of capping fastening is also represented in Figure 7; t is the plain
pin the stem of which is flat or oblong in cross section the said pin having a head
at one end and a projection u at its other end so that when the pin t has been
passed through the capping f and glazing bar a a neck or contraction is situated
between the projection u and the capping for receiving the fastening fork or
cotter as seen in the Drawing. By means of the fastening fork the pin t is
secured in its place and the capping fixed to the glazing bar as represented in
Figure 11 and the perspective view Figure 7.
A fastening fork of the kind represented in Figure 12 may be used at both
sides of the capping. In this case the pin t has at each end a projection of the
kind marked u. The top of the glazing bar in Figures 7 and 10 is expanded and
the top of the capping f has a corresponding figure given to it for engaging with
or under the said top of the glazing bar when the capping is forced home on the
glass. By this means the capping is secured very firmly in its place.
Figures 14, 15 and 16 represent snugs constructed according to my Invention
for supporting the glazing bar at each end, the said snugs also serving to attach
the bar to the supporting bearers. Each snug x is furnished with a slot or
opening w having a shape suitable. to receive the glazing bar a. The opening in
the snug represented in Figures 14 and 15 is of a shape proper to receive the
glazing bar represented in Figure 1 and the opening in the snug Figure 16 is of a
shape suitable to receive the glazing bar represented in Figures 7 and 10.
When the glazing bar is to be supported at the lap of the glass I construct a
double or compound snug of the kind represented in side elevation in Figure 17ª ;
longitudinal section in Figure 17B and end elevation in Figure 17° so as to support
the glazing bar at the required levels.
The supporting parts 2, 3 of the double snug are at different levels (see
Figure 17B) the part 2 being used for supporting the upper glazing bar 4 and the
part 3 for supporting the lower glazing bar 5 as seen in Figure 17B. The base of
each of the parts 2, 3 of the snug has a figure proper to receive the lower half
of the glazing bar while each of the cap parts 2 3 has a figure proper to receive
the upper half of the glazing bar.
By means of the clip y represented in Figure 7 and shown separately in
Figure 17, which clip is made to embrace the glazing bar a, the upper sheet of
glass z (Figure 7) is prevented from sliding down; z' is a gutter of sheet zinc fixed

page_text: between the sheet of glass 2 and the lower sheet 2. The gutter
condensed moisture from the upper sheet z to the trough e.

Invention and in what manner the same is to be performed I declare that what
I claim is of "Improvements in Glazing Conservatories Roofs of Railway Stations
Arcades and other Buildings and Structures'
