We, FRANCOIS ALPHONSE BROCHARD pere, and EMILE ANTOINE ALPHONSE
BROCHARD fils, both of Paris, France, Locksmiths, 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 :-
This invention relates to removable glazed frames or covers of iron, wood and iron,
or wood, designed to protect espaliers and counter-espaliers and, in general, fruit
trees and vines against frost, hail, and other inclement weather. This improved
glazed frame or cover besides protecting any produce or crop also promotes the
maturing of fruit, such as cherries, peaches, grapes or the like. The said frame or
cover by reason of its particular construction and simple arrangement on a wall or
other support, possess material advantages over the means heretofore employed as
regards safety, strength, and lightness of the structure.
In the accompanying drawing are illustrated a general arrangement and details of
the glass cover constructed in accordance with our invention.
Figure 1 is a front view of the cover.
Figure 2 a side view of the same.
Figure 3 shows, to an enlarged scale, a supporting rod.
Figure 4 a fang plate to which the supporting rod is fastened.
Figure 5 another fang piece.
Figure 6 a wire or pin bent to the shape of an S.
Figure 7 a hook plate.
Figure 8 a mounting designed to hold the glass plates without the use of putty.
The improved removable glass cover comprises a frame of angle iron, U-iron,
T-iron, or the like, which is placed against a wall or other support and secured by
means of fanged fastening pieces b and plate hooks a on the one hand, and on the
other hand by means of supporting rods g connected with the fang plate c and the
angle iron e forming the lower edge of the cover.
Each of the fang pieces 6 consist of a rod bent so as to form at one end a fang by
spreading its two extremities, and at the other end an opening large enough to

page_text: receive side by side two plate hooks a similar to those represented in Figure 7.
This fang piece can also be made of plate iron."
The fang plate c is of the shape shown in Figure 4. The supporting rod g engages
at one of its extremities with the fang plate c, and at the other extremity with the
lower angle iron e. An S-shaped wire or pin prevents the supporting rod from
leaving the hole in the fang plate c, and the said rod can be disengaged therefrom
only by lifting it vertically.
The glass is maintained upon the iron bars of the frame by means of a mounting
of sheet zinc or galvanized sheet iron, which is of U-shape in transverse section and
provided with flanges (Figure 8). These mountings fit over the web of the T-irons
of the frame, and are kept in place by an S-shaped wire or pin which passes through
holes pierced for this purpose in the iron and mounting. In this manner the use of
putty is obviated and the glass can be removed from the frame and replaced thereon
at will. The mountings employed at the edge of the frame possess only one flange.
Our improved cover is capable of resisting the action of the strongest winds,
without the least danger to the glass. It can be readily mounted and dismounted,
and in good weather can be put away in a very small space after the glass has been
removed. The nature of the materials employed for the cover can be varied without
changing the feature of the invention, for instance wood, or metal and wood combined,
can be employed. in the construction of the same.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is :
A removable glass cover characterized on the one hand by the mode of its arrange-
ment on a wall or other support through the medium of fang plates or pieces b and c,
hook plates a and supporting rods g connected to the lower edge e of the cover frame
and stop wires or pins d, and on the other hand by the mode of securing the movable
glass plates through the medium of U-shaped mountings provided with flanges
(Figure 8) which are caused to press the glass plates against the flange of the T
or irons of the cover frame, substantially as, and for the purpose, described.
