Improvements in Devices for Fixing and Making Watertight Sheets
of Glass and other Materials Employed in Covering Roofs and
other Structures.
I, JOHN ARTHUR HOPE, of 55 Lionel Street, in the City of Birmingham,
Manufacturer, do hereby declare the nature of this invention to be as follows:-
My invention relates to means of fastening in a secure and weather proof manner
sheets of glass or other material employed in covering roofs, flats or sides of railway
stations, greenhouses and other structures or places without the use of putty or like
substance.
My object is to improve upon the existing means of glazing without putty.
My invention consists in a new arrangement and construction of the various parts
required in such glazing so combined as to produce a better result.
In carrying my invention into effect I provide for the interior of the glass roof
or other structure bars, or lengths of channel iron, with the trough side downwards or
away from the glass. I place upon the flat bottom of the channel iron a long strip
of metal such as copper, or zinc, shaped of such section that the centre part fits
upon the channel iron, while the sides are bent downwards and upwards to form two
troughs, one on each side of the said channel iron. The outer edges of the two
troughs are arranged to preferably turn outwards and terminate at a level higher
than the centre part. I place the edges of the glass sheets upon the said
raised outer edges, and I cover the glass by means of a copper zinc or like strip
formed of an elastic cross section such as is given by a central semi-circular part
having on each side flange parts with outer edges bent downwards to cause the
metal to hear upon the glass, at the inner and outer edges of the said flange.
I pass a screwed bolt through the botom of the channel iron, and through
perforations in the metal strips, preferably holding the bolt stationary from the
interior, while being screwed up, and for this purpose I may provide the bolt with
a slit or square head to enable it to be held while the nut above is being turned.
I firmly attach the inner metal strips to the channel iron by nuts screwed home
upon the said strips, thus making a watertight joint over the hole in iron, and 1
fasten the outer strip also by nuts on the ends of the screw bolts.
The edges of the glass sheets are held clear of the channel iron by the raised
edges of the inner strips, and so an elastic connection is secured and the glass firmly
held in a watertight manner. Any water which may pass under the top cap collects
between the underside of the glass and the central flat portion of the trough, and
is then carried to the outside by the troughs formed by bending up the edges of the
inner strips.
I vary the shape and length of bolt with its head and nuts or attachments to suit
any particular requirement.
Similarly I sometimes employ a lead outer cap or cover with its shape and
configuration so arranged as to permit of its being bent down over the glass.
Dated this 26th day of January 1894.

Improvements in Devices for Fixing and Making Watertight Sheets
of Glass and other Materials Employed in Covering Roofs and
other Structures.
I, JOHN ARTHUR HOPE, of 55 Lionel Street, in the City of Birmingham,
Manufacturer, 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 means of fastening in a secure and weather-proof manner
sheets of glass or other material employed in covering roofs, flats or sides of railway
stations, greenhouses and other structures or places without the use of putty or like
substance.
My object is to improve upon the existing means of glazing without putty.
My invention consists in a new arrangement and construction of the various parts
required in such glazing so combined as to produce a better result.
Referring to the accompanying sheet of drawings-
Figure 1 is a section showing my invention carried into effect, and
Figure 2 is a similar section showing a modification.
In carrying my invention into effect I provide for the interior of the glass roof
or other structure bars or lengths of channel iron A Figure 1 with the trough side
downwards or away from the glass. I place upon the flat bottom of the channel
iron a long strip of metal B such as copper or zinc, shaped of such section that the
centre part fits upon the channel iron A while the sides are bent downwards and
upwards to form two troughs B' one on each side of the said channel iron. The
outer edges of the two troughs are arranged to preferably turn outwards and
terminate at a level higher than the centre part. I place the edges of the glass
sheets D upon the said raised outer edges and I cover the glass by means of a
copper zinc or like strip C formed of an elastic cross section such as is given by a
central semi-circular part having on each side flange parts with outer edges bent
downwards to cause the metal to bear upon the glass at the inner and outer edges
of the said flange as shown at Figure 1.
I pass a screwed bolt E through the bottom of the channel iron and through
perforations in the metal strips B, preferably holding the bolt stationary from the
interior, while being screwed up, and for this purpose I may provide the bolt
with a slit E¹ or square head to enable it to be held while. the nut above is being
turned.
I firmly attach the inner metal strips to the channel iron by nuts screwed home
upon the said strips, thus making a watertight joint over the hole in iron, and I
fasten the outer strip also by nuts E2 on the ends of the screw bolts E.
The edges of the glass sheets are held clear of the channel iron A by the raised
edges of the inner strips, and so an elastic connection is secured and the glass
firmly held in a watertight manner. Any water which may pass under the top
cap collects between the underside of the glass and the central flat portion of the
trough, and is then carried to the outside by the troughs B' formed by bending up
the edges of the inner strips.
The modification shown in Figure 2 is in all respects similar to that shown in
Figure 1, but the wood bar or support A' is substituted for the channel iron A.
I vary the shape and length of holt with its head and nuts or attachments to
suit any particular requirement. Similarly I sometimes employ a lead outer cap
or cover with its shape and configuration so arranged as to permit of its being bent
down over the glass.

page_text: 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 arrangement and sections of strips with their fastenings as and for the
purposes herein before described.
