PROVISIONAL SPECIFICATION.
An Improvement in Glazing Horticultural and other Buildings.
JOSEPH PRATT 12 Kirkdale Sydenham London S.E. Horticultural Builder do
hereby declare the nature of this invention to be as follows :-
My invention relates to an improvement in glazing roofs of conservatories, green-
houses, and generally where glass is used, and has more particularly for its object,
a better and more secure manner of fixing each pane of glass in the roofs of horti-
cultural structures whether putty is used or not in the rebates, and further this
invention provides for the retaining the glass from slipping as it often does, through
perished putties, or tension, or the action of the atmosphere it also obviates the use
of brads or nails or zinc points, hooks &c. which are now systematically used.
I therefore make a double pointed or forked metal clip or peg with a flange bent
at right angles, to receive the corner of the bottom edge of each pane of glass, when
laid between the rafters in the rebates. I then drive the points into the rafter
(with the flange supporting the glass) thus I press the glass in its bed, and retain it
there by my clip or peg.
And thus this invention forms a secure and permanent
fastening, which is much needed and is essential for the above referred to
horticultural and other buildings.
Dated this First day of January 1894.
COMPLETE SPECIFICATION.
An Improvement in Glazing Horticultural and other Buildings.
I, JOSEPH PRATT of 12 Kirkdale, Sydenham, London, S.E., Horticultural
Builder 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 :-
My invention relates to an improvement in glazing roofs of conservatories, green-
houses, frame lights, and generally where glass is so used.
And has particularly for its object to fix in a firm secure and substantial manner
each pane of glass in its place or position between the rafters or astragals forming
roof or otherwise in horticultural buildings or other structures where glass is used
thus preventing the panes of glass moving or slipping down (as is often the case
under the existing system of glazing) through tension, compression, weather action
or the falling out of brads or pieces of metal commonly used for security.
It is usual in glazing glass structures to "bed" the panes of glass with putty and
to drive a nail or "brad" into the rafter or astragal and often a piece of zinc bent
in the form of a "S" hook hung on the top of the bottom pane as the glass is laid
pane after pane between the before mentioned rafters, and then lay on what is
known as a "face putty" along the rafter on the outside of the glass.
This method frequently fails in keeping the glass in position and invariably causes
leakage.
To avoid the use of the before mentioned brad or zinc, I provide a double pointed
clip turned down at right angles, made of brass, copper, zinc, or steel, or any other
suitable material see Figures 1 and 2.
The glass is then laid in the rebates of the rafters or astragals forming the roof
of a glass structure (with or without "bed putty”).

page_text: I then take my clips (handed) and drive them into the rafters in their respective
positions fitting them at each bottom angle of each pane of glass (Figure 3) the
panes are thus kept permanently in their position-the use of "face putties"
rendered absolutely unnecessary.
The clip being double pointed fixes each pane, and prevents the glass from slipping
down, and from rising up or being misplaced from any cause (except breakage)
which is very essential in such work as horticultural building.
The clip can be easily withdrawn by using a bradawl for the purpose of repair.
In order to provide for fixing small panes of glass, I make the clip in a modified
form, as shewn in Figure 4.
The accompanying illustrations describe the above particulars
Figure 1 a drawing of the referred to clip turned down at right angles and forming
the clip (right hand).
Figure 2, similar to Figure 1 (left hand).
Figure 3 section of glass roof shewing the clips partly driven in to retain the
glass in its position.
Figure 4 shewing the clip modified (as referred to above) for small panes of glass
and can be used either hand.
Having thus particularly described and ascertained the nature and purpose of
this my invention and in what manner the same is to be performed, I declare
that what I claim is ;
A clip made of metal or other suitable material for the better fixing, securing and
maintaining the glass (or other material used in a similar manner) in conservatories
greenhouses, and horticultural or other buildings, to act substantially and for the
purpose hereinbefore set forth.
