improvements in kooi, кoonight and Oupola-light Glazing.
1, CHARLES ETTLES, Joiner, of 65, Leadside Road, Aberdeen, 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 to improvements in roof, rooflight and cupola light glaz-
ing and has for its object to enable the glazing to be effected rapidly and
efficiently and at a moderate cost.
But in order that my said invention may be readily understood and easily
carried into effect, I will proceed to describe the same with reference to the
accompanying sheet of diawings in which
Fig. 1 18 an elevation and
Fig 2 a plan of one astragal and a portion of the sill, constructed in accord-
ance with my improvements
Fig. 3 is a cross section of the astragal and
Fig 4 is an elevation of an astragal showing the arrangement when two or more
sheets or panes of glass, overlapping each other, are employed
Fig 5 is a cross section of a hollowed fillet for diagonals
Referring to the said drawings I employ a wooden astragal A. of suitable size
and having its lower edge moulded in the usual way
The said astragal 18 pie-
ferably of a section as shewn in Fig 3 that is to say provided with a rebate to
receive the glass and with two grooves or channels B running lengthways for the
purpose of collecting and leading the condensed vapour away. The glass 18
retained in position by means of the capping C of wood or similar material which
also 18 formed with two grooves or channels for the reception of stups of
asbestos D or other similar packing, whereby, when the capping is firmly screwed
to the astragal, a perfectly watertight joint is made The sill E 18 rebated to
enable the glass to lie close thereto and prevent smoke, dust or water from drift-
ing in It is also flashed with lead to pieserve the woodwork and is formed with
a channel e for receiving the water from the channels B, which channel 18
provided with outlets or short channels as shewn. The astragals may be fitted
and secured in any convenient way to the sill E and purling F so that they
can be removed, when required, without causing injury to any of the parts The
bottom of the glass pane is supported by a clip on clips G of biass or other metal
secured to the sill E of the 100f
The ridge flashing 18 fixed or secured by ridge straps of any convenient form.
In the event of diagonals being required a hollowed or grooved fillet, as shewn
in section Fig 5, may be un along the edges of the diagonals for the purpose of
removing any condensed water, as in the case of the astragals
When two or more panes of glass are emploved the astragal is preferably formed
as shown in Fig 4 to allow the panes to overlap each other and the capping dove-
tailed on checked to suit Or the astragal may be of the form first described and
the capping angled or checked to receive the glass

page_text: Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is:
1 The general arrangement, construction and combination of parts constituting
my improvements in roof, rooflight and cupola light glazing, substantially as
herein before described and shewn in the accompanying drawings.
2 In 100f, rooflight and cupola light glazing the wooden astragal A having
two moisture collecting channels or grooves B and a wooden capping or cover C
provided with grooves c for the reception of asbestos or other packing D, the said
astragals being connected to a sill plate E, constructed as set forth, all substan- I
tially as herein before described in the accompanying drawings
