COMPLETE SPECIFICATION.
I, WILLIAM HARDING of 4 Magdalen Street, Exeter in the County of Devon,
Horticultural Builder, do hereby declare the nature of said invention for
IMPROVEMENTS IN GLAZING GREENHOUSES AND OTHER STRUCTURES" and in
what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:-
This invention consists in the employment, in glazed structures, of zinc bars, made
I-shaped in section, between the upper and lower members of which the sides of
the panes of glass are placed.
"
The panes after having been readily slid into position, are maintained in place
by means of clips secured to the purlins and turned over the lower ends of the
panes.
And in order that my said invention may be properly understood, I now proceed
more particularly to describe the same with reference to the accompanying sheet of
illustrative drawings and the figures and letters marked thereon.
Fig. 1 on the accompanying sheet of drawings represents a front view of part of
a side of a glazed inclined roof, as of a greenhouse or similar structure, constructed
in accordance with my said invention. Fig. 2 is a transverse section of the same.
The panes a, a and b, bare placed, at their adjacent sides, between the upper and
lower members of the zinc bars c and c¹, made I-shaped in section, as shown. The
bar c is secured to the purlin d by the pin or bolt e. After having been readily
slid into position, the panes a and b are maintained therein by the clips m, secured
to the purlin d and turned upwards over the lower ends of the panes.
The panes a¹ and 6¹ are similarly supported at the corresponding purlin next
below, to which the bar c¹ is bolted or otherwise secured.
The top rail A is recessed to receive the top of the bar c and the panes a and b.
The purlin d is similarly recessed to receive the bar c' and the panes a¹ and b'.
Placing and maintaining in position the panes .of glazed structures are, under
this invention, readily effected, and any desired pane may be removed by turning
back the bent ends of the clips supporting it and withdrawing the same from
between the members of the zinc bars.
At the ends of the roof where the panes abut upon the frame, the form of the
zinc bars may be modified to receive the panes at one side only, and the lower
-member may be curved, as shown.
Bolts or pins D secure the bars to the frame.

page_text: The panes are arranged to overlap, and the bars are made in lengths as required.
By making the bars of zinc the requisite degree of stiffness is obtained and
economy effected.
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, in glazed structures, of the zinc bars shaped as illustrated, and
the clips or their equivalent secured to the purlins, whereby the panes of glass are
readily placed and maintained in position or withdrawn therefrom, substantially as
herein before described and shown upon the accompanying sheet of drawings.
Dated this 21st day of January 1884.
