IMPROVEMENTS IN THE CONSTRUCTION OF GLASS ROOFING to be as follows
Year: 1884

page_text: I JOHN SEWELL of Isle Lane Knaresborough in the County of York Horti-
cultural Builder do hereby declare the nature of said invention for "IMPROVEMENTS
IN THE CONSTRUCTION OF GLASS ROOFING to be as follows :—
"
The object of my improvements is to provide a simple arrangement for readily
fastening the glass on the roof of conservatories and other places, such roof when
glazed in accordance with my invention is not only perfectly air and water tight,
but also the glass can be readily removed when breakages or other causes require
such removal. For this purpose the bars which are used for supporting the glass.
are made flat on the top, and the glass laid on overlapping each other lengthways
but butting against or close to each other sideways as is usual when no rebate is
employed.
A bed of putty is laid on the top of the bars into which the glass is bedded but my
invention particularly refers to the mode of securing or fixing the glass in position
after it is laid on the bars, and for this purpose I provide a wooden pin having.
a flat or other convenient shaped head. In the direction of the pin's axis there is
a small hole which passes through the head and nearly through to the point of
the pin.

•
The corners of each piece of glass are cut away or rounded off, so that when the
plates are placed in position on the bars, spaces are formed and corresponding holes
are provided in the bars into which the hollow wooden pins are passed, fitting
loosely therein after which a metallic plug or nail is passed down the centre of the.
pin and forced through, the end thereof which expands the end of the pin in the
wooden bar at the same time drawing down the head of the pin tightly on
the glass holding the glass firmly in position.
To avoid any liability of breaking the glass when forcing down the metallic pin
I provide a cushion of putty beneath the head of the pins.
.
On removing the central plug or nail which is readily done, the wooden pin
becomes slack again in the bar and can be readily withdrawn when required.

1, JOHN SEWELL of Isles Lane, Knaresborough in the County of York, Horti-
cultural Builder do hereby declare the nature of said invention for "IMPROVEMENTS
IN THE CONSTRUCTION OF GLASS ROOFING" and in what manner the same is to
be performed to be particularly described and ascertained in and by the following
statement:-
The object of my improvements is to provide a simple arrangement for readily
fastening the glass on the roof of conservatories and other places, Buch roof when
glazed in accordance with my invention is not only perfectly air and water tight,
but also the glass can be readily removed when breakages or other causes require
such removal.
For this purpose the bars which are used for supporting the glass are made flat
on the top, and the glass laid on overlapping each other lengthways but butting
against or close to each other aideways as is usual when no rebate is employed.
A bed of putty is laid on the top of the bars into which the glass is bedded, but
my invention particularly refers to the mode of securing or fixing the glass in
position after it is laid on the bars, and for this purpose I provide a wooden pin
having a flat or other convenient shaped head.
In the direction of the pins axis there is a small hole which passes through the
head and nearly through to the point of the pin..
The corners of each piece of glass are cut away or rounded off, so that when the
plates are placed in position on the bars, spaces are formed and corresponding holes
are provided in the bars into which the hollow wooden pins are passed, fitting
loosely therein after which a metallic plug or nail is passed down the centre of the
pin and forced through the end thereof which expands the end of the pin in the
wooden bar at the same time drawing down the head of the pin tightly on
the glass holding the glass firmly in position.
To avoid any liability of breaking the glass when forcing down the metallic pin
I provide a cushion of putty beneath tho head of the pins..
On removing tho central plug or nail which is readily done, the wooden pin
becomes slack again in the bar and can be readily withdrawn when required.
And in order that my invention may be more completely understood reference is
given to the accompanying drawings and to the letters and marks thereon.
DESCRIPTION OF DRAWINGS,
Figs 1 and 2 are transverse sections. Fig 3 a plan looking and Fig 4-an end
elevation showing my improvements in the construction of glass roofing.
A represents the bars which are used for supporting the glass, these are made
flat on the top band the glass o is laid on overlapping each other lengthways as
shown at d Figs 1, 2 and 3 but butting against or close to each other sideways as
shewn at e Figs 3 and 4 as is usual when no rebate is employed. A bed of putty
is laid on the top of the bars into which the glass o is bedded. My improvements
particularly refer to the mode of fixing the glass in position after it is laid on
the bars, and for this purpose I provide a wooden pin ƒ having a flat or other
convenient shoned bead a

page_text: In the direction of the pins axis I provide a small hole h which passes through
the head and nearly through to the point of the pin.
The corners of each piece of glass are cut away or rounded off so that when
the plates are placed in position spaces are formed and corresponding holes are
provided in the bars A into which the wooden pins f are passed, after which a
metallic plug or nail 7 is passed down the centre of the pin f as shewn at Fig 1 and
then forced through the end thereof as shewn at Fig 2 causing the end of the
pin to be expanded at the same time drawing down the head g tightly on the
glass c thereby holding such glass firmly in position.
To avoid any liability of breaking the glass when forcing down the metallic
plug or nail I provide a cushion of putty beneath the heads of the wooden pins f.
On removing the central plug or nail , which is readily done, the wooden pin f
becomes slack again in the bar A and can be readily withdrawn when required.
In some cases the central plug or nail 7 may be dispensed with and the wooden
pins f driven tight into the bars.
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
The employment of wooden pins f either with or without the central plugs or
nails in the construction of glass roofing substantially as herein set forth.
