page_text: use as applied to hot bed frames, but practically a portable green house, with
adjustable top, as regards height from the ground.
The frame proper could be supported on legs such as K, or provision for sinking
sume into the ground when so required.
The double frame may contain fluid such as water or alcohol, or some compound
not easily acted on by changes of temperature.
The frame may be made to take between brick or other walls, and be capable
of being raised or lowered as before described.
Provision should of course he made for opening the sides or other parts for
ventilation, such as are shown by the hinged ventilators marked L.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what I
claim is:-
1. In hot bed and other frames and structures used, in horticulture, the frame A
in combination with the super-posed frame B, the latter being free to rise and fall
within the other, and means for operating same so that the distance of the frame B
from the mould can be regulated and adjusted, all substantially as and for the
purposes set forth.
2. In combination with such structures as those described, and claimed by
Claim 1, the means described for raising and lowering such frames, all constructed,
arranged, and acting, substantially as and for the purposes hereinbefore described
and illustrated with reference to the accompanying drawing.

PROVISIONAL SPECIFICATION.
Improvements in and connected with Hot Bed and other Frames and
Structures used in Horticulture.
I, BENJAMIN GREEN SKIPWORT, of 40 & 42 Queen Victorin Street, in the City
of London, Outfitter, do hereby declare the nature of my said invention to be as
follows:-
Heretofore in the construction of hot bed and other frames, and structures used
in horticulture, tor forcing or for protecting plants, flowers, and vegetables, from
atmospheric influences, there is not sufficient provision for regulating the distance
hetween, for example, the glass and the mould, the only menus usually provided
in hot bed frames for raising the glass or light, being by the addition of a second
upper frame, placed upon the frame proper.
Now the object of my invention is to so construct and arrange the frame proper,
and its cover, that the height of the latter can be regulated and adjusted with
the greatest facility, and as circumstances may require.
According to my invention I make the frame proper in such manner that it
will receive within it the sides and ends of a super-posed glazed frame. This
glazed frame is or may be supplied with a removable or sliding light or top, and
means are provided for raising or lowering the aforesaid glazed frame.
A convenient construction is, when the frame is of rectangular shape, to make
the frame proper double, by forming an internal and external frame arranged at
such a distance apart, that the top glass frame can pass into the aperture formed
around the frame proper, such aperture being of such a depth as to allow the light
of the glazed frame to come close, if desired to the mould; when the frame proper
is not made double the glazed frame should be arranged to slide inside or outside
the frame proper.
The glazed frame may be raised or lowered and its position adjusted by any
known and convenient mechanical means. I find that one convenient way is to
arrange a rack on both sides, into which a piniou (or pinions) works driven at
the side by a crank handle, with a pawl to stop the rack when required, and
consequently the top glass frame. Or chains or cords passing over pulleys with
counter-weights at the ends, may be employed. Or the height of the glazed frame
might be adjusted by arranging apertures in the side frame through which pins
could be inserted, to retain the glazed frame at any desired height.
By my invention I not only provide a frame with an adjustable top frame for
use as applied to hot bed frames, but practically a portable green house, with
adjustable top, as regards height from the ground.
The frame proper could be supported on legs, or provision for sinking same into
the ground when so required.
The double frame may contain liquid such as water or alcohol, or some compound,
not easily acted on by changes of temperature.
The frame may be made to take between brick or other walls, and be capable
f being raised or lowered as before described.

Improvements in and connected with Hot Bed and other Frames and
Structures used in Horticulture.
I, BENJAMIN GREEN SKIPWORTH of 40 and 12 Queen Victoria Street, in the City
of London, Outfitter, 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:-
Heretofore in the construction of hot bed and other frames and structures
used in horticulture, for forcing or for protecting plants, flowers, and vegetables,
from atmospheric influences, there is not sufficient provision for regulating the
distance between, for example, the glass and the mould, the only means usually
provided in hot bed frames, for raising the glass or light, being by the addition of
a second upper frame, placed upon the frame proper.
Now the object of my invention is to so construct and arrange the frame proper
and its cover, that the height of the latter can be regulated and adjusted with
the greatest facility, and as circumstances may require."
In order that my invention may be readily understood I will describe same
with reference to the accompanying drawings, whereon Fig. 1 is a perspective
view of a frame constructed according to my invention, showing the lights in their
raised or elevated position, and Fig. 2 is a transverse sectional elevation of the
same frame.
According to my invention I make the frame proper A, in such manner that
it will receive within it the sides and ends of a super-posed glazed frame B This
glazed frame B is or may be supplied with a removable or sliding light or top (
and means are provided, such as those hereafter described, for raising or lowering
the aforesaid glazed frame B.
A convenient construction is, when the frame is of rectangular shape, to make
the frame proper A double, by forming an internal and external frame as shown
at Fig. 2, arranged at such a distance apart that the top glass frame Bean pass
into the aperture D formed around the frame proper A, such aperture being of
such a depth as to allow the light of the glazed frame B to come close, if desired,
to the mould. Although not so shewn in the drawing, when the frame proper A
is not made double, the glazed frame B should be arranged to slide inside or outside
the frame proper A.
The glazed frame B may be raised or lowered, and its position adjusted by any
known and convenient mechanical means. I find that one convenient way is to
arrange a rack or ratchet wheel E on one or both sides, driven at the side by a
crank handle F, with a pawl to stop the ratchet when required, and consequently
the top glass frame. The ratchet is mounted on a spindle H to which chains cr
cords are fixed leading from the glazed frame B. Or chains or cords, passing
over pulleys, with counter-weights at the ends, may be employed. Or the height
of the glazed frame might be adjusted by arranging apertures in the side frames
through which pins could be inserted. to retain the glazed frame at any desired
height.
By my invention 1 not only provide a frame with an adjustable top frame for
