COMPLETE SPECIFICATION.
Improved Means and Method for Glazing Greenhouses and
the like.
I JOHN MAKEPEACE of The Gardens Dilhorn Stoke on Trent Builder do
hereby declare the nature of this invention and in what mauner the same is to be
performed, to be particularly described and ascertained in and by the following
statement-
The object of this invention is to provide a system of glazing suitable for
greenhouses, vineries, conservatories and other like structures which said system
shall be simple inexpensive, and effective to a degree not obtained by any systems of
glazing now in use.
I provide simple sash bars running from the ridge of the roof to the eaves, these
sash bars are flat on the top, and are placed at distances from centre to centre equal
to the width of the panes of glass it is proposed to employ. On the top surface of
the sash bars I place a layer of putty so that when the edges of adjacent sheets of
glass are pressed together the putty is partially squeezed up between them owing to
the slight irregularities of the faces of the cutting edges and then a thoroughly
watertight joint is effected.
For the farther securing the sheets of glass, I provide small lead clips of equal
length to the width of the sash bars and about " wide, these clips are rebated on the
underside of one of the longer edges. A clip is placed at the foot of each sheet of
glass on every sash bar and so adjusted that the sheet of glass fits into the rebate of
the clip and is thus supported and secured; the remaining portion of the clip serves
to keep in position the sheet of glass immediately below. It will thus be seen that
there is a
clip at each corner of every sheet of glass, and at the same time every clip
assists to secure four sheets of glass. The row of panes next the ridge have their top
edges fitted into a rebate in the capping, and secured with putty in the ordinary way.
And the same treatment is observed in the case of the ends of the roof where the
row of panes from ridge to eaves have their edges placed in a rebate in the end rafter
and secured with putty. The clips are fixed to the sash bars by galvanized "screws
one to each clip. And as the panes of glass fit closely to each other it is necessary
to cut away a small portion of the corner of each pane to allow the screw to pass
through to the sash bar. In order that my Invention may be more fully understood
I will now proceed to describe the accompanying sheet of drawings, in which the
like letters of reference indicate the like parts throughout.
Figure 1 shews a section of a roof glazed in accordance with the principles of my
Invention. A A represents the lead clips before described. B is a lead clip of a
different form to secure and support the bottom row of panes, this clip is a simple
hook of the same width as the other clips, or otherwise as desired. Fshews the
galvanized screws and G the sheets of glass. U is the sash bar which carries the
glazing-the sash bars themselves are supported by purlins and rafters according to
the span and extent of the roof. D represents the ridge capping and E indicates the
eaves gutter.
Fig. 2 is a plan to a larger scale illustrating the joint of four panes of glass and
shewing one of the lead clips securing the corners of the said four adjacent sheets of
glass as before described. A is the lead clip. F is the galvanized iron screw and
G G G G are the sheets of glass. C is as before the sash bar. The vertical dotted
lines indicate the sash bar the horizontal dotted lines shews the lap of the panes of
glass and the circular dotted lines shew how the glass is cut away to take the
screw.
Fig. 3 illustrates how the panes of glass are cut to allow of the passage of the
screw which fastens the clip and the two lower panes to the sash bar as before
mentioned.

page_text: An advantage of this system of glazing is that it may be executed with ease by
persons who have had little or no experience in glazing. It is further very cheap
and light and perfectly wind and water-tight.. A further advantage is that there
are no outside rafters or sash bars and consequently no external painting is
required.
The general appearance of a roof glazed according to my invention, is that of one
immense sheet of glass bounded only by the ridge and the end rafters.
As my invention is capable of some modification without departing from the
principle thereof I do not restrict myself to materials, dimensions, or to the precise
form or placement of the parts thereof.
Having now particularly described and ascertained the nature of my said Inven-
tion, and in what manner the same is to be performed I declare that what I
claim is :-
(1.) Improved means and method of glazing for greenhouses, vineries, and the
like all as herein described in the specification and illustrated by accompanying
drawings.
(2.) In improved means for glazing greenhouses and vineries the use of a rebated
head clip in combination with a galvanised iron screw for the purpose of securing
together sheets of glass which are hedded in putty upon a sash bar all as before
stated in this specification and illustrated in accompanying drawings.
