PROVISIONAL SPECIFICATION.
An Improvement in Greenhouses and such like Structures,
I, JOIN THOMAS BURROWS FAIRBAIRN, of The Edentown Nurseries, near the
City of Carlisle, Horticulturalist, do hereby declare the nature of this invention
to be as follows:-
My invention relates to the construction of green-houses or the like in such
manner that the sloping glass roof frames can be readily removed, and can then
be utilised for covering garden frames, or protecting spaces occupied by tender
crops or for other horticultural purposes.
The roof frames, instead of being separate and arranged to slide up or down
the slope, are arranged to run on rollers along the length of the green-house
and are hinged together, the hinges at the one edge of each frame being set
opposite to those at the other edge, so that the frames, when they are withdrawn
from the roof, fold one over the other in zig-zag fashion on to a truck or other
conveyance by which they can be removed. They can be replaced by unfolding
them successively and drawing them along the roof to their proper positions,
where they are secured by suitable fastenings.
When they are used for protecting crops, they can be unfolded and run along
rails more or less elevated, or along wire ropes supported at suitable intervals
above the ground.
Each glass frame may have a hinged window for ventilation. When the
roof slope is of considerable width, the frames may be mado in several parts,
forming tiers which can be separately withdrawn and replaced.
The lower edge of each upper frame, in this case, is made to overlap the upper
edge of the frame immediately below it, so as to cover the junction of the frames
from the weather.

An Improvement in Greenhouses and such like Structures.
I, JOHN THOMAS BURROWS FAIRBAIRN, of The Edentown Nurseries, near the
City of Carlisle, Horticulturalist, 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 the construction of greenhouses or the like in such

page_text: manner that the sloping glass roof frames can be readily removed, and can then
be utilised for covering garden frames, or protecting spaces occupied by tender
crops or for other horticultural purposes, as I shall describe with reference to
the accompanying drawings.
Fig. 1 is a longitudinal section, and
Fig. 2 is a transverse section of a greenhouse with roof frames according to
my invention. Fig. 3 is a perspective view shewing the application of the frames
to cover an area of ground. Fig. 4 is a section to an enlarged scale of parts
of adjacent frames.
The roof frames a instead of being separate and arranged to slide up or down
the slope, are arranged to run on rollers b along the length of the greenhouse
and are hinged together, the hinges at the one edge of each frame being set
opposite to those at the other edge, so that the frames, when they are withdrawn
from the roof as shewn in Fig. 1 fold one over the other in zig-zag fashion on
to the ground or on to a truck or other conveyance by which they can be
removed.
They can be replaced by unfolding them successively and drawing them along
the roof to their proper positions, where they are secured by suitable fastenings.
The edge of each frame is preferably made as shewn in Fig. 4 to overlap the
edge of the next, and in the lower of the two overlapping parts is formed a
small gutter to run off water entering between the frames.
When they are used for protecting crops they can be unfolded and run along
rails more or less elevated, or along wire ropes supported at suitable intervals
above the ground.
Each glass frame may have a hinged window for ventilation. When the
roof slope is of considerable width, the frames may be made in several parts,
forming tiers which can be separately withdrawn and replaced.
The lower edge of each upper frame, in this case, is made to overlap the upper
edge of the frame immediately below it, so as to cover the junction of the frames
from the weather.
Having now particularly described and ascertained the nature of this
invention and in what manner the same is to be performed, I declare that what
I claim is:-
-
1. The construction of the glass roof frames of greenhouses and the like and
their supports so that the frames can be run longitudinally off the roof in zig-
zag folds, substantially as described.
2. The combination of the glass roof frames above referred to with rails or
their equivalents supported above the ground, substantially as and for the purpose
set forth.
