Improvements in Glazing Roofs, Skylights, Horticultural Buildings,
and the like.
GEORGE EMERTON of Westoning in the County of Bedford Carpenter and
Builder do hereby declare the nature of this invention to be as follows:-
The object of my invention is to provide simple and cheap means for securing
glass in roofs skylights horticultural buildings and the like without the aid of putty
which shall be extremely convenient and efficient both in so securing the same and
in removing and replacing the same when desired.
To carry out this object I plough a longitudinal groove preferably rectangular
in section out of each side of all the bars of the roof skylight horticultural building
or other thing that is to be glazed which groove extends the whole length of the
bar and is at the desired distance from the upper or outer surface thereof and
parallel therewith or thereabouts. I then take a sheet of metal or other suitable
material it may be zinc and therewith cover the upper or outer surface of the
bar and I force it into the grooves on both sides and below the grooves I spread
the lateral edges of this sheet out at right angles or thereabouts to the plane of
the bar and projecting as far therefrom as may be desired and these projecting
lateral edges can most conveniently be bent into the shape of a gutter. The
pieces of glass whether of a square or an oblong or other suitable shape are slid
one by one into the complementary grooves of the two opposing bars from and
through the bottoms thereof and when one piece has attained its desired position I
secure it therein by a disc preferably of metal which is pivoted eccentrically on the
side of one or it may be of both of the bars above the groove therein in such wise
that it acts as a cam and in the upper or intermediate cams a detent or projection
or recess is made whereby the lower edge of this piece of glass is held and retained
the next piece of glass is then slid along the grooves until its upper edge passes
the desired distance under the lower edge of the upper piece of glass when it in its
turn is secured in position by one or more other and similar cams and so on until
the whole space between these two opposing bars has been glazed when the last
cam without a detent or projection only presses down the last piece of glass on the
lower edges of the grooves and then I can very conveniently eccentrically pivot on
the lower end of the bar a square or other plate which can be so turned as to
engage the lower edge of this last piece of glass. To remove the glass this process
is reversed the plate and the last cam are so turned that the lowest piece of glasso
can be drawn out of the grooves and then the other cams are successively so
turned that the other pieces of glass can successively also be drawn out of the
grooves.
When a part of the roof or skylight or other thing is to be made to open
separately it can be hinged as is usual at its upper edge which hinge would be
covered in the ordinary manner and the outer lateral edge of the sheet that covers
as aforesaid each of the outer bars of this part would not be guttered but would be
formed to cover the bar of the fixed part of this roof skylight or other thing next
to this opening and of course these outer bars would not require grooves on their
outer sides and the lower edge of this opening part can be raised by an hinged bar
or other usual and suitable appliances.

Improvements in Glazing Roofs, Skylights, Horticultural Buildings,
and the like.
I GEORGE EMERTON of Westoning in the County of Bedford Carpenter and
Builder 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 this my invention is to provide very simple and cheap means for
securing glass in roofs skylights horticultural buildings and the like without the
aid of putty which shall be extremely convenient and highly efficient in so securing
the same while at the same time whensoever it may be necessary or desirable so to
do the glass can quickly and easily be removed and then replaced.
In order the more clearly to explain this my invention and in what manner the
same is to be performed I refer to the accompanying drawing wherein
Figure 1 is an elevation of the side of a part of one of the bars of a roof or
skylight or horticultural building or other thing that is to be glazed according to
these my improvements.
Figure 2 is a transverse section of the same taken at a bin Figure 1 and
Figure 3 is an elevation of the lower end of the same.
All the bars A of the roof or the skylight or the horticultural building or the
other thing that is to be glazed are made of any usual or other desired sizes and
shapes and sections as may be suitable in each particular case and as a general rule
out of each side of cach bar A. I plough or I otherwise create therein a groove B
of the necessary dimensions for the purposes hereinafter stated and which most
conveniently can be and preferably is rectangular in section as is shewn in the
drawing and this groove B extends the whole length of the bar A and is at the
desired distance from the upper or outer surface thereof and is parallel with such
upper or outer surface or thereabouts. I then take a sheet D of metal or other
suitable material it may perhaps preferably be zinc and of the proper dimensions
for the purposes hereinafter stated and therewith I cover the upper or outer
surface of the bar A and I bend it down and over this upper or outer surface of
the bar A and [ force it into the grooves B on both sides and below these
grooves BI spread out the lateral edges of this sheet D at right angles or there-
abouts to the plane of the bar A and projecting as far therefrom as may be desired
or as may be arranged for by the breadth of the sheet D and these projecting
lateral edges can most conveniently and suitably be bent into the shape of and can
form gutters E as is shewn in the drawing and the whole length of the bar A is 80
covered and fitted with this sheet D made and arranged and formed in manner as
herein before described preferably in one piece or length although two or more
pieces or lengths may in like manuer be used when desired which pieces or lengths
could be joined together or could be caused to overlap each other or could be
otherwise treated in any usual and suitable manner.
The pieces of glass whether of a square or an oblong or other suitable shape
are slid one by one successively into the complementary and opposing grooves B
of two adjacent bars A from and through the bottoms thereof and when one piece
of glass F has attained its desired position I secure it therein by a disc H
preferably of metal which is pivoted eccentrically as is shewn at H' on the side of
one or it may be of each of the bars A above the groove B therein in such wise
that it can act as a cam and in or on each of the upper or intermediate cams I a
detent or projection or recess K is so formed and created in any convenient and
usual or other manner as to be capable of holding and retaining the lower edge of
this piece of glass F and it is also very convenient to form on this cam H the lip
or prolongation L whereby it is obvious that when the cam H has been properly
turned therefor and when the piece of glass F has been slid along the grooves Ba

page_text: short distance above this cam H so that the same can be turned back again into
the position shewn in Figure 1 the piece of glass F may be allowed to slide back
downwardly until its lower edge has been caught by the detent or projection or
recess K and then it will be impossible that this piece of glass F can by accident
misadventure or otherwise undesignedly get out of or leave its required and proper
position. The next piece of glass F is then in a similar manner slid along the
grooves B until its upper edge has passed the desired and arranged for distance
under the lower edge of the adjoining next above piece of glass F when in its turn
it is similarly secured in position by another cam or by other cams H made and
fitted and formed and used in manner as hereinbefore described and so on until the
whole space between these two adjacent and opposing bars A has been duly glazed.
The last or lowest cam M can be made and fitted and formed and used in the same
manner as is the cam H hereinbefore described but it is preferably a simple plain
cam without the aforesaid detent or projection or recess and lip or prolongation in
which case when the last or lowest piece of glass has been slid into its desired
position in manner as hereinbefore described this cam M is so turned as to press
the same down on the lower edges of the grooves B as is shewn in Figure 3 and
then I can most conveniently pivot on the lower end of the bar A in the proper
position a plate N of such a size and shape as that when the same is turned into
one position it will engage and retain the lower edge of this last or lowest piece
of glass For it may be as is shewn in Figure 3 the lower edges of the two last
or lowest pieces of glass F on opposite sides of the bar A. and that when the same
is turned into another position or other positions it will release the said lower edge
or lower edges.
To remove the glass this process and cycle of operations hereinbefore described
is reversed that is to say: the plate N if any and the cam or cams M are so
turned as to release the lowest piece of glass and allow it to be drawn out of
the grooves B and then the next above piece of glass F it may be is necessarily
released by falling down in the grooves B out of the reach of the detent or
projection or recess K thus disengaging itself therefrom so soon as the upper
edge of the lowest piece of glass has been withdrawn from under the lower edge
of this next above piece of glass or if this is not necessarily the case this next
above piece of glass can be pushed up far enough to allow the cam or cams H to
be so turned as to release the same and allow it to be drawn out of the grooves B
and so on until all the pieces of glass have successively been drawn out of the
grooves.
When a part of the roof or skylight or horticultural building or other thing that
has been or is to be glazed in manner as hereinbefore described is to be made and
arranged to open separately it can be hinged as is usual at its upper edge which
hinge could be covered in the ordinary manner and the lower edge thereof can be
raised by an hinged or jointed bar or by other usual and suitable appliances. In
this case it is obvious that grooves need not necessarily be created in the outer
sides of the outer bars of this opening part of the roof or skylight or horticultural
building or other thing and the outer lateral edge of that sheet that covers in
nanner as herein before described each of these outer bars would not be bent down
and over and into the outer side of this bar and it may be guttered as herein before
described but would be formed and arranged to spread over and cover the adjacent
outer bar of the fixed part of this roof or skylight or horticultural building or
other thing next to this opening in any convenient and suitable manner and it is
likewise obvious that grooves need not necessarily be created in the outer sides of
these adjacent outer bars of this fixed part of the roof or skylight or horticultural
building or other thing and the outer lateral edge of that sheet if any that covers
in manner as hereinbefore described each of these outer bars could be comple-
mentarily formed and arranged or it may be if desired could be cut away and
removed.
It is also sufficiently obvious that the same method of fitment and arrangement
could be observed and followed in and with the outside or corner bars of the roof

page_text: or skylight or horticultural building or other thing that has been or is to be glazed
in manner as hereinbefore described and no further description or explanation is or
can be needed.
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
The arrangement and combination of parts and appliances constituting my
improvements in glazing roofs skylights horticultural buildings and the like
substantially as hereinbefore described and shewn in the accompanying drawing.
