do hereby declare the nature of this invention to be as follows:-
I provide a stout framework of wood for the sides & ends, and for the roof I have
rafters of a suitable substance, these I fix to the ridge and to the sill or top of frame-
work at the bottom by nails or screws for permanent buildings. I then fix battens
of a suitable substance across the rafters at any distance that will suit the sizes of
glass intended to be used. I then lay the squares of glass on these battens in rows
similar to a slated roof the bottom ends overlaping the tops of row under it but to
prevent the glass from slipping down or the wet from coming in through the joints,
I have provided pieces of the ordinary church window lead cut the same length as
the squares of glass to be used. To the bottom end of these lead strips I fix a piece
of zinc or other sheet metal bent so as to form sockets for the corners of the squares on
each side to rest in, this metal socket is brazed or sweated on to the lead strip on both
sides and is a little wider than the lead this allows a tack or screw to be driven or
screwed through it into the batten so fixing the lead strip & preventing the glass
from lifting up or slipping down. At the other end of the lead strip I also braze or
sweat on a piece of sheet metal but on the underside only and not bent over the end.
This is left open so that the glass can easily be slipped in either from the inside or
outside of the house.
By this method of glazing no putty or similar substance is required. Broken
squares can be easily & quickly replaced either from the inside or the outside of the
house. The whole of the wood work is covered and protected from the external
atmosphere & can be easily painted from the inside by any amateur there being no
cutting in required it has the merit of being strong light & durable and can be
supplied at a very low price and what is more important it can be maintained at`a
very trifling outlay there being no perishable parts exposed.
•
For the portable buildings I make a similar wood frame work but I provide sockets
made either of cast iron or sheet metal brazed to suit any angle that may be required.
Into these sockets 1 insert the ends of the frame work & fix them with screws.
They are strong & light easily taken to pieces can be closely packed and are not easily
broken.
I glaze them in the same way as the permanent buildings the glass & lead strips
can be easily taken out & packed also in a small compas.

COMPLETE SPECIFICATION.
Improvements in the Construction and Glazing of Greenhouses and
other Structures.
'I, JOHN MCMURRAY LYON, of 304 York Road, Wandsworth, in the County of
Surrey, Builder and House Decorator, do hereby declare the nature of this invention
to be as follows:-
. My invention relates to certain improvements in the construction and glazing of
greenhouses and other structures, and it has for its objects, first, facilitating the
construction and re-construction of portable buildings such as greenhouses;
secondly, glazing the roofs of greenhouses and other structures in such a manner
and

page_text: that broken squares can easily and quickly be replaced, either from the inside or the
outside of the house.
I attain these objects in the manner illustrated in the accompanying drawings in
which Figures 1. and 2 Sheet No. 1. are views in broken side and end elevation
respectively showing the construction of the frame of my improved portable
building. Figures 3. 4. and 5. Sheet No. 1. are views in side and end elevation and
plan respectively of one of the main sockets, and Figures 6. 7 and 8. Sheet No. 1.
are views in side and end elevation and plan respectively of one of the sockets for
the rafters. Figures 9 and 10. Sheet No. 2. are views in plan and section respectively
showing my improved system of glazing or roofing. Figures 11. and 12. Sheet
No. 3. are views on an enlarged scale-in front and side elevation respectively of
one of the carriers for the squares of glass, slate, or other roofing material, and
Figure 13. Sheet No. 3. is a transverse section thereof. Figures 14. and 15 are views
-on an enlarged scale-in front and side elevation respectively showing a modification
in the construction of the carriers.
Throughout the several views similar parts are marked with like letters of
reference.
Referring to Figures 1 to 8. Sheet No. 1. of the accompanying drawings. The
framework of my portable building is connected together by means of suitably
shaped sockets made either of cast iron or sheet metal blocked or stamped into shape
and brazed or sweated at the joints. For an ordinary building four different patterns
would be required, that marked A for the lower members of the frame, B for the
upper members and end rafters, C for the other rafters, and D for the junction of
the rafters with the ridge beam. The various members of the frame are fitted into
these sockets and fixed by spikes or screws, so that they may readily be withdrawn
when it is desired to take the building to pieces. It will be understood that the
size and shape of these sockets will depend entirely upon the size and shape of the
building. The building may be roofed or glazed in the ordinary manner but preferably
by my improved method as it is easily removed and replaced. Figures 9 to 14
Sheets No. 2. and 3, of the accompanying drawings illustrate this, and making
reference to these views I will more particularly describe it. Across the rafters X of
the roof are fixed battens x x etc. at a suitable distance apart proportionate to the size
of the squares of glass or other material to be used. The squares A A etc. are placed
side by side in rows, the bottom ends overlapping the tops of those in the row under
it. The squares are fixed and held in place by means of carriers B formed of ordinary
church-window lead, or its equivalent, cut into the required lengths and closed at one
end either simply by pressure or moulding or by means of a zinc or other metal cap b.
sweated or brazed on to the lead strip as illustrated by Figures 11. and 12. Sheet
No. 2. of the accompanying drawings. On to the back of each carrier B are fixed
by sweating or brazing two strips 61 61 of zinc or other suitable metal. The function
of these strips 6' 61 is to fix the carrier to the battens which they do by being turned
over the edges of the battens x x etc. as illustrated and then secured to the top or
back thereof by means of tacks or screws.
As a modification the cap b. may be made in one piece with the lower strip 6' as
illustrated by Figures 14 and 15 Sheet No. 3. of the accompanying drawings or both
the
cap
b. and the strips 6' 6' may be formed in one piece with the carrier B either by
drawing, moulding, or stamping.
It will be seen that this system is applicable for all kinds of roofs whether glazed,
slated, or covered with squares of any other material, and that it has the advantages
that broken squares can easily and quickly be replaced either from the inside or the
outside of the roof, that the whole of the woodwork of the roof is covered and
protected from atmospheric influences and can easily be repainted from the inside,
and that in case of slating roofs, a considerable saving is effected in the number of
slates required. When this system is used for slating boarded roofs, I form or fix the
strips 66¹ transversely on the carriers B so that they can be tacked or screwed down
to the boarded roof instead of to the battens thereof.
TE
I wish it to be particularly understood that I do not limit myself to the exact

page_text: details of construction herein before described and illustrated by the accompanying
drawings, but hold myself at liberty to make such changes and alterations as fairly
fall within the spirit and scope 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, I declare that what I
claim is ;-
1st. The improved construction of portable buildings as set forth.
2nd. The improved method of glazing or slating roofs as set forth.
3rd. Fixing and supporting squares of glass, slate, or other roofing material by
means of carriers formed of church-window lead, or its equivalent, and having strips
formed on or fixed to them adapting them to be fixed to the battens or boards of a
roof, as and for the purpose set forth.
