And in order that our said invention may be the better understood we will
proceed to explain the same with reference to the accompanying sheet of drawings
in which:-
Fig. 1 represents a section of a greenhouse ventilated according to this invention.
Fig. 2 plan of portion of roof of same shewing ventilating pane.
Fig. 3 side view of ventilating pane.
Fig. 4 view of underside of same.
The same letters denote the same parts in all the figurës.
a is the. sliding pane of glass b c d are bands of copper or other suitable
material passing round the same and soldered or otherwise fastened together
e is a ring attached to the band c to which is secured the cord f passing round
the pulleys and h k is a cleat to secure the cord f so as to retain the pane a
in any desired position.
The pane a is secured to the roof in such a manner as to allow of it being
raised or lowered by the clips l.
When the pane a is lowered an aperture is left between the panes m and n
for the ingress or egress of air when the said pane is raised the said aperture
is closed.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
In a method of ventilating greenhouses and other glazed structures the use of a
sliding pane or sheet of glass surrounded by one or more bands of metal or other
