PROVISIONAL SPECIFICATION.
Improved Means for Holding Sheets of Glass and other Material.
I, FRANK BULLEN RENDLE of 5 Victoria Street, in the County of Middlesex,
Engineer, do hereby declare the nature of this invention to be as follows:-
This invention relates mainly to my well known system in which the sheets of
glass or other material rest on the top of the sides of a metal trough and are held
in position by an arched strip of metal secured to the trough by bolts and nuts the
heads of the bolts lying in the trough beneath lips formed by turning in the edges
of the sides of the trough.
Such troughs have hitherto been made by drawing a single strip of copper or
zinc through dies but according to this invention I make them in several pieces of
such form that they or the principal part of them can be rolled in iron or steel.
Thus the sash bar may be made up of a rectangular trough with two Z shaped pieces
of metal fixed one on each side, the upper limb of the Z forming the inwardly
turned lip and the lower limb being bent upwards to form a gutter. Or the sash
bar may consist of a V shaped bar with similar Z shaped pieces on each side. Or
it may consist of a double T shaped bar the heads of the two T's being in a line
with each other and forming the bottom plate whose ends are turned up to form
gutters in this case the lips are formed of angle bars fixed to the legs of the Ts..
In any of these cases the sash bar may be strengthened by a central rib rolled
on it.
Or again the sash bar may be made of two similar halves fixed together.
The arched strip may be replaced by a T shaped strip of stiff or pliable metal
and in this case the inwardly projecting lips are omitted, the bolts for securing the
strip passing through the sides of the trough and the stem of the T.
Sometimes I make the horizontal joints between the sheets of glass or other
material as butt joints. In such cases I insert between the two sheets a metal strip
turning the upper edge down on to the lower sheet of glass and with the other edge
form two gutters or channels. The two ends of this gutter are carried into channel
bars such as those before described so that condensed water is thus carried off.

COMPLETE SPECIFICATION.
Improved Means for Holding Sheets of Glass and other Material.
I, FRANK BULLEN RENDLE, of 5 Victoria Street, in the County of Middlesex,
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 relates mainly to my well known system in which the sheets of
glass or other material rest on the top of the sides of a metal trough and are held
in position by an arched strip of metal secured to the trough by bolts and nuts the
heads of the bolts lying in the trough beneath lips formed by turning in the edges
of the sides of the trough.
Such troughs have hitherto been made by drawing a single strip of copper or
zinc through dies but according to this invention I make them in several pieces of

page_text: such form that they or the principal part of them can be rolled in iron or steel.
Thus the sash bar may be made up of a rectangular trough with two Z shaped pieces
of metal fixed one on each side, the upper limb of the Z forming the inwardly
turned lip and the lower limb being bent upwards to form a gutter. This con-
struction is shewn at Figure 1. Or the sash bar may consist of a V shaped bar with
similar Z shaped pieces on each side as shown at Figure 2. Or it may consist of a
double shaped bar the heads of the two T's being in a line with each other and
forming the bottom plate whose ends are turned up to form gutters :-in this case
the lips are formed of angle bars fixed to the legs of the T's. This construction is
shewn at Figures 3 and 4. In any of these cases the sash bar may be strengthened
by a central rib rolled on it as shewn at Figures 1 and 4.
Or again the sash bar may be made of two similar halves fixed together as shewn
at Figure 5.
The arched strip may be replaced by a T shaped strip of stiff or pliable metal
and in this case the inwardly projecting lips are omitted, the bolts for securing the
strip passing through the sides of the trough and the stem of the T. This
construction is shown at Figure 6.
Sometimes I make the horizontal joints between the sheets of glass or other
material as butt joints. In such cases I insert between the two sheets a metal strip
turning the upper edge down on to the lower sheet of glass and with the other edge
form two gutters or channels. The two ends of this gutter are carried into channel
bars such as those before described so that condensed water is thus carried off. This
construction is shewn at Figures 7 and 8.
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 :-
:-
1. Troughs with inturned lips for holding sheets of glass or other material made
in two or more pieces and formed either wholly or principally of rolled bars
substantially as described.
2. Troughs with inturned lips substantially as described and shown at
Figures 1, 2, 3, 4 and 5.
3. The method of holding the sheets of glass or other material to the troughs by
means of shaped pieces substantially as described and shown at Figure 6.
4. The method of making the horizontal joints substantially as described and
shown at Figures 7 and 8.
5. Means for holding sheets of glass and other material substantially as described
and shown in the drawings.
