PROVISIONAL SPECIFICATION left by the said Christopher Causley at the
Office of the Commissioners of Patents on the 27th February 1880.
CHRISTOPHER CAUSLEY, of West Hackney, in the County of Middlesox, Timber
Merchant. "IMPROVEMENTS IN GLAZING THE ROOFS AND WALLS OF HORTI-
CULTURAL AND OTHER STRUCTURES."
This Invention relates to improvements in glazing.
According to my Invention the glazing of roofs of greenhouses, hothouses, railway
stations, forcing or garden frames, or any description of buildings, large or small, is
effected rapidly & easily without putty, and so as to efficiently keep out the
weather; also no painting is required, and the effect is very durable.
In accomplishing my Invention I attach to or form in cach upper side of each
sash bar or rail a gutter of metal, on the upper outer edge of which the successive
panes of glass rest. With small sash bars or rails these two gutters may be
united at the top and pass over the top of the sash bar or rail.
A metal cap is
put over the top of the sash bar or rail and screwed down thereto, its outer edge
covering the inner edge of the glass. This edge is turned in underneath, and forms
a sort of spring, which on the cap being screwed down is compressed closely down
upon the glass and makes a very close joint, and one which will efficiently keep
out the weather. Each pane overlaps the pane below it for a small distance, as in
ordinary glazing. Should any water get in it will be carried away by the gutters.
Also any condensation which may be drawn to the sash bars or rails will pass into
the guttering and be carried away instead of collecting and dripping down, as in
ordinary glazing.
The outer cap is made up in lengths corresponding with the lengths of the
panes of glass, and as each lower length is fixed the next upper pane rests on its
upper end, the lower inturned edge being removed for a short length to allow of
the cap overlapping the pane for a short distance, say, half an inch. Sides of
buildings can be glazed in this way.

This Invention relates to improvements in glazing the roofs and walls of horti-
cultural and other structures.
According to my Invention the glazing of roofs of greenhouses, hothouses, forcing
and garden frames, railway stations, or any description of buildings, large or small,
is effected rapidly and easily without putty, and so as to efficiently keep out the
weather; also no painting is required, and the work is very durable.
My Invention is illustrated in the accompanying Drawings (which Drawings
are to be taken as part of this Specification), reference being had to the letters and
Figures marked thereon. On the upper side of each sash-bar A (see Fig. 1), which
is suitably formed for the purpose, I fix a cap B of metal, and preferably of drawn
zinc. This cap is so formed as to present two shoulders b for the glass C to rest
on, and two gutters 6' underneath the edges of the glass, one on each side of the
sash bar. An outer cap D is then placed over all, so as to cover the two edges of
the glass, and is then attached by screw to the sash bar, the screw passing through
the lower cap, as shown. The lower edges of the upper cap D are turned in, as
seen, and thus an elastic edge is presented to the glass, allowing cap D to be
pressed firmly down and making a perfectly tight joint. Should any water by
any possibility find its way through this joint, and also pass the underneath joint
of the glass, it will fall into the gutter underneath, and so be run off. The outer
edges of the gutters are made so as to leave a space between them and the glass
to allow any condensation forming on the interior of the glass to run into the
gutters, and so be carried away instead of dripping down, as with ordinary glazing.
Figs. 2 and 3 illustrato modifications in the form of the lower cap B, Fig. 3 showing
also another method of fixing cap D. The screw which passes through cap B into
the wood is surrounded by a tube E soldered to the metal cap B, thus preventing
water soaking in round the screw. Figs. 4 and 5 show the application of my
Invention to the ends of the roof or other glazing, or whenever the caps do not
pass entirely over the top; Fig. 6 is an elevation of a sash-bar with my improve-
ments attached, and as shown in section at Fig. 1, which is taken at the line a, b,
Fig. 6, and showing the junction of two panes of glass. In this form it will be
seen that the caps B & D are put on in lengths similar to the panes of glass, the
lengths of the lower cap being packed up, so as to rest close against the glass
throughout. This is seen clearly at Fig. 7, which is a longitudinal sectional
elevation of Fig. 6 taken on the centre line; G is the packing. Fig. 8 illustrates
a modification where the lower cap is continuous throughout the length of the sash
bar. In this case the panes do not rest on said cap throughout their length, but
only at or near one end. Fig. 9 illustrates my improvements on plan. It also
illustrates another feature of my Invention, namely, cutting the glass at an angle
instead of square. Thus formed the inner edge of each pane arrests any moisture
running down the inside of the glass, and gives it a direction towards the gutters,
which it thus enters and is run off.
Sides of buildings can be glazed in this way.
Slates may be attached to roofs instead of panes of glass, as hereinbefore
described. For this application of my Invention I prefer the form illustrated_at

page_text: I claim as my Invention to be secured by the hereinbefore in part recited Letters
Patent, the improvements in glazing and slating, substantially as hereinbefore set
forth and described and illustrated in the accompanying Drawings.
In witness whereof, I, tho said Christopher Causley, have hereunto set my
hand and seal, this Twenty seventh day of August, in the year of our
Lord One thousand eight hundred and eighty.
