Improvements in Glazing Horticultural Buildings and Appliances,
and applicable to the Glazing of other Structures.
I, GEORGE JAMES LYON COXHEAD, of 240 St. Ann's Road, South Tottenham,
Clerk, 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 :-
The object of my invention is to produce an improved system of glazing
horticultural buildings, structures and appliances and although primarily intended
for use in the construction of what are known as garden frames is equally adapted
for use in the glazing of larger structures such as greenhouses, conservatories,
photographic and other studios or the like.
In carrying out my invention I make the end bars of the structure to be glazed
single rabbetted and the intermediate bars double rubbetted: the former being
consequently shaped more or less in cross-section, and the latter of inverted
T shape in cross section.
The bars may be made of any suitable material. On the horizontal ledges of
these rabbetted bars I place strips of felt or the like which have previously been
impregnated or otherwise treated so as to be impervious to water. 1 do not
confine myself to any particular mode of waterproofing the felt, as any process
at present in use for the purpose will equally meet the requirements of my
invention. The strips of felt or the like may be of the same breadth as the
width of the horizontal ledges of the rabbets on which they are laid.
On top of the felt I place the sheets of glass of sufficient width to extend from
one vertical ledge of the rabbet to the other and of sufficient length to overlap one
another.
The glass is kept in position by any suitable means, but preferably by metal
holders more or less square or rectangular in section and having a rabbet in one
corner, one side of the rabbet being of about the same width as the thickness of
the glass used in the glazing; but the rabbet may be sloped or stepped to take
various thicknesses of glass. These holders have formed in them a hole passing
through them from side to side and parallel to the rabbet above mentioned.
The holders are placed at the lower corners of the sheet of glass, one at each
side, and are held in position by a nail or the like passing through the hole aud
driven, screwed or otherwise inserted into the vertical ledge of the rabbetted bars
of the frame or other structure. To render the description clearer I annex a sheet
of drawings in which Fig. 1 shows a longitudinal section and Fig. 2 a transverse
section through A. B. of part of a frame glazed by my improved method. Fig. 3
is an isometrical view of one of the holders 8 or keeping the glass in position. The
full lines show the approximate shape when used for one thickness of glass and
the dotted lines, the sloping rabbet for accommodating various thicknesses of glass.
Similar letters refer to the same parts in each of the figures.
a is an end bar or style, b an intermediate one, e c¹ the glass, d the impregnated
felt on which the glass is retained by the rabbet e in the holders. The holders f
are held against the frame by the pins or nails g, passing through the hole made
in each of them for the purpose.
In Fig. 3. e. represents the sloping part of the rabbet when so made to take
glass of more than one thickness.

page_text: I do not confine myself to the relative proportions or actual conformation of
parts as herein described or shown in the accompanying drawings as any or all of
them may be varied without departing from the spirit of my invention.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed declare that what I
claim is :-
1. The method of glazing horticultural and other structures and appliances by
resting the glass on ledges covered with waterproofed felt. The glass being held in
position by special holders, the whole substantially as described in the above
Specification and exemplified in the accompanying drawings.
2. The use of waterproofed felt in glazing horticultural and other structures,
substantially as hereinbefore described and exemplified in the accompanying
drawings.
3. The special holders having straight, sloped or stepped rabbets for accommodating
glass of one or various thicknesses and retaining the same in position substantially
as hereinbefore described and exemplified in the accompanying drawings.
Dated this 28th day of September 1895.
