Improvements in the Means and Method of Fixing and Making
Secure and Watertight Sheets of Glass and other Materials
employed in Covering Roofs, Flats, or Sides of Railway Stations,
Greenhouses, and other Structures or Places.
We, HENRY DONALD HOPE and JOHN ARTHUR HOPE, both of 55 Lionel
Street, in the City of Birmingham, Horticultural Engineers, do hereby declare
the nature of this invention to be as follows:-
Our invention relates to means of glazing or fastening sheets of glass and like
materials for roofs and other purposes, and our object is to provide a system of
glazing without putty in which the outside or upper strip is made in lead or other
soft durable metal.
In one method of carrying our invention into effect we arrange an inner bar of
approximately section with a central outward projection formed with a dovetail
groove passing along its length. The two sides of the T head pass under the
glass and turn upwards being preferably provided with longitudinal grooves to
contain strips of packing material. The inner rib of the T projects within the
structure opposite to the dovetail groove hereinbefore mentioned. We place the
edges of the adjoining sheets of glass upon packing laid in the grooves of the two
sides of the T, and we form a lead strip with an inner part shaped to fit the said
dovetail groove and two side wings which are bent over when the glass is in
position so as to lie all along the glass touching préférably at the extreme edge
and at a curved surface a little further in. These two side wings are formed in
the first instance to project straight outwards and they are bent over after the
dovetail part has been slipped into the dovetail groove. When so bent over the
highest part left is preferably a central bead or rounded part opposing the dovelail
portion. This central bead allows ladders or platforms to be placed upon the roof
without deteriorating or crushing the lead wings which keep the roof, watertight.
By this our device we are enabled to readily repair the roof by lifting up any
particular wing in order to take out a broken glass sheet and replace it. The
T section iron bar within the glass may be considerably varied in configuration and
so arranged that two troughs run along the bar, within the packing pieces, these
troughs being provided to drain off any water which may leak through.
Other sections may be used than T section. A channeled section for example
may be adopted providing two ribs within the glass; a central projection to carry
the dovetail groove and two side ribs curved upwards to form two troughs and
having in the ends longitudinal grooves to carry packing.
By our invention we are enabled to very readily and cheaply glaze roofs, flats or
sides of railway stations, greenhouses or other structures without the use of putty
or like substance, in such manner as to be dust tight as well as watertight.

Improvements in the Means and Method of Fixing and Making
Secure and Watertight Sheets of Glass and other Materials
employed in Covering Roofs, Flats, or Sides of Railway Stations,
Greenhouses, and other Structures or Places.
We, HENRY DONALD HOPE, and JOHN ARTHUR HOPE, both of 55 Lionel'
Street, in the City of Birmingham, Horticultural Engineers, 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:—
Our invention relates to means of glazing or fastening sheets of glass and like
materials for roofs and other purposes, and our object is to provide a system of
glazing without putty in which the outside or upper strip is made in lead or other
suitable metal arranged for the permitting of the ready formation of a durable and
water and dust tight connection.

In the accompanying sheet of explanatory drawings to be hereinafter referred
Figure 1 is a sectional elevation of one form of inner bar for a roof or other
framing with our improved outside or upper strip attached thereto.
Figure 2 is a part plan of the inner bar without the upper strip.
Figure 3 is a sectional elevation representing a modified form of the inner
bar with the outside or upper strip attached thereto, and Figure 4 is a plan of the
same.
Figure 5 is a sectional view to represent the method of securing the sheets of
glass or other material.
The same reference letters in the different views indicate the same parts.
In one method of carrying our invention into effect we arrange an inner bar A
of approximately T section as shown at Figure 1 with a central outward projection
formed with a dovetail groove A¹ Figures 1 and 2 along its length. The two
sides of the T head pass under the glass and turn upwards being preferably
provided with longitudinal grooves such as a a¹ to contain strips of packing material.
The inner rib A of the T projects within the structure opposite to the dovetail
groove herein before mentioned. We place the edges of the adjoining sheets of
glass upon packing of tarred hemp or other suitable material laid in the grooves
of the two sides of the T, and we form a lead strip B with the inner part shaped
to fit the said dovetail groove and the two side wings B2 B3 which are bent over
when the glass is in position so as to lie all along the glass touching preferably at
the extreme edge and at a curved surface a little further in. These two side wings
are formed in the first instance to project straight outwards and they are bent over
after the dovetail part has been slipped into the dovetail groove. When so bent
over the highest part left is preferably a central bead or rounded part such as B¹
Figures 1, 3, 4, and 5, opposite the dovetail portion. This central bead allows
ladders or platforms to be placed upon the roof without deteriorating or crushing
the lead wings B2 B3 which keep the roof watertight. By this our device we are
enabled to readily repair the roof by lifting up any particular wing or a portion of
the same in order to take out a broken glass sheet and replace it. The T section
iron bar within the glass may be considerably varied in configuration and so
arranged that two troughs run along the bar within the packing pieces, these
troughs being provided to drain off any water which may leak through.
Other sections may be used than T section. A channeled section for example
such as shown at Figure 2 may be adopted providing two ribs C C' within the
glass, a central projection C to carry the dovetail groove, and two side ribs C³ C*

page_text: curved upwards to form two troughs D D¹ and having in the ends longitudinal
grooves a a¹ to carry packing.
The method of securing the sheets of glass or other material by bending over
the two side wings B2 B3 of the lead or other strip B is clearly illustrated at
Figure 5.
By our invention we are enabled to very readily and cheaply glaze roofs, flats,.
or sides of railway stations, greenhouses or other structures, without the use of
putty or like substance, in such manner as to be dust tight as well as watertight.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is ;-
1. The improved method of fixing and securing sheets of glass or other material
substantially as herein before described, and as illustrated in the accompanying
drawings.
2. In glazing and like operations the use of a lead or other metal strip, such as B,
shaped and arranged substantially as and for the purposes hereinbefore described,
and as illustrated in the accompanying drawings.
3. The construction of the inner bar of a roof or other framing having one or
more inner ribs or projections, a central upper or outward projection, with a dove-tailed
groove formed therein, and side ribs curved or shaped to form troughs and grooves,
substantially as and for the purposes herein before described, and as illustrated in
the accompanying drawings.
4. The improved general combination and arrangement of the inner bar A, with
hemp or other packing material, and the outer strip B, substantially as and for
the purposes herein described.
