PROVISIONAL SPECIFICATION.
An Improved Fastening or Stay for the Lights of Garden Frames.
JOHN JARVIS Horticultural Builder "Avondale " Halifax Road Cambridge do
hereby declare the nature of this invention to be as follows:-
An iron plate 3" long 1" wide ths" thick or thereabouts, having an eye or
staple riveted into the centre of same, to which is attached a peice of flat iron,
" wide x " thick or thereabouts, it having a hole punched or drilled near to
one end larger enough (for it to "work" easily on staple). The length of same
to be 9" to 12" or to any length required. At intervals along the edge (of the
said peice of flat iron) incisions or slots are made extending to the centre of the
said peice of flat iron & then taking a downward course for about of an inch.
Then upon
the bottom rail of light or sash is screwed an iron plate in the centre
of which a Tee peice of iron is riveted, the top or head of the T peice running
parallel with the plate; also with the centre of gravity; the shank of Tee peice
being about " long the top or head being about 1" long made out of round iron
or thereabouts.
To apply the same, take the above flat iron bar (the plate of which is screwed
on to the outside of garden frame near to the top edge, just underneath the
Tee peice on the bottom edge of light take the flat iron bar in one hand & with
the other hand raise the light to height required bring the shank of Tee peice to
rest into slot nearest to the shank upon which it will rest, securely until the light
is lifted up & the flat peice of iron is moved to admit of light being lowered.

The top end of the above bar of flat iron has an open slot running down the
same about 1" deep by ths" wide or thereabouts, to receive the shank of
Tee peice; (this is to set the light open to the full length of flat bar). But in
conjunction with the same, a round peice of inch bar iron, 3 ft. long or any length
required with one end flattened down (for about 4" along the bar) flattened to an
inch wide by a " thick or thereabouts, having in its centre a slot 1" wide x 2 in.
long or thereabouts, to admit of the top or head of the aforesaid Tee peice, (the
bottom end of iron bar is pointed to stick into the ground,) by taking the bar of
iron & holding in position parallel with the top or head of Tee peice which will
admit of same easily, then lowering the other end of iron bar to the ground the
top end becomes instantly locked on to the shank Tee peice, thence raising the
light to any height required up to the full length of the said bar.
This is for setting the light open for filling &c. of frame.

COMPLETE SPECIFICATION.
An Improved Fastening or Stay for the Lights of Garden Frames.
I, JOHN JARVIS, Avondale Halifax Road Cambridge Horticultural 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:-
My invention relates to a new or improved prop or stay for the lights of garden
frames, green houses, hot houses and the like.
This prop is fully illustrated in the accompanying drawings, in which
Figure 1 is a side view showing the application of my improved prop or stay to
the glass frame of a garden frame.

page_text: Figure 2 is an elevation of the prop, and Figure 3 a modification thereof.
Figures 4 and 5 are two elevations at right angles to one another of another
form of prop.
Figures 6 and 7 are respectively a side view and a plan of a staple and plate.
Figures 8 and 9 are respectively a side and a front view of a device for con-
necting the garden frame to the prop.
My improved prop consists of a flat bar a terminated with a fork 6 at the top
and with a rounded end a' at the bottom whereby it is pivoted to the garden
frame F, while it is furnished along one of its vertical edges with a series of
notches 1, 2, 63, 64, 6º.
'
The end a¹ is connected to the garden frame F by means of an eye or staple c
rivetted or otherwise fixed to a plate d secured by screws e to the end of the
frame F, while the device shown in Figures 8 and 9 is likewise screwed into the
end of the glass frame f. and consists of a T piece rivetted or otherwise fixed to a
plate. This T piece is composed of a head y and of a shank g' which is
designed to enter one of the notches b', 6² according as the frame f is to be
more or less raised, while the said head y assists in fully securing the frame f in
a raised position, its end projecting below the end of each notch as clearly shown
in Figure 1. The prop shown in Figure 3 instead of terminating with a fork b.
(Figure 2) by means of which the frame f. may be supported in its highest
position, is terminated with a handle i whereby it may be conveniently manipulated;
this prop being more specially applicable to front lights or overhead ventilators.
When it is merely required to support the frame fin a raised position at a
constant height, the prop or stay shown in Figures 4 and 5 may be used. This
prop consists of a cylindrical rod j having a pointed end k and terminated at the
top with a flattened and enlarged part 1 furnished with a central slot m.
point is forced into the ground, and the head g of the T piece fixed to
the frame is passed through the slot m until the shank g¹ rests upon the lower
end of the latter.
The
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 improved stay or prop for supporting the lights of garden frames, hot-
houses and the like, and its two modifications substantially as herein described and
shown and for the purpose set forth.
