PROVISIONAL SPECIFICATION.
Improvements in Hot-bed and similar Frames.
I, LOUIS BOULAT of Troyes, in the Republic of France, Gardener, do hereby
declare the nature of this invention to be as follows
--
The present invention refers to improvements in hot-bed and similar frames and
consists of two single frames hinged together thus forming a frame with a double
fall.
Each of the sides of the hot-bed consists in this instance of preferably sheet iron
fixed to the glass-carrying frame by means of angle irons. The corners of the frame
carrying the glass are braced together by triangular pieces of iron. To the inside of
the longitudinal side pieces is fixed a triangular piece of wood which rests on the
ground. This wood may however be substituted by bent irons rivetted to the side
the upper part thereof forming the angle irons for connecting the side to the frame
proper or the side itself may be bent at the top and fastened to the frame without any
angle iron.
To facilitate the transport of the frames, they are provided with handles and abut-
ments or projections are formed on the top of the sides to prevent one frame
from touching another when piled up in a stack; this prevents the breakage of the
glass.
The middle or ridge of this double frame is supported by a wooden upright fixed
to a plate which rests on the ground. In the top of the upright is fixed a metal
blade passing between the two hinged frames for the purpose of facilitating the
turning of the latter round the axes of their hinges.
The frames are hinged together preferably by simple galvanised iron wire but
they may if desired be hinged together by ordinary hinges rivetted or screwed to
the frames.
By means of these frames a hot-bed of any desired length can easily and quickly
be constructed in any desired place without any preliminary preparation by simply
placing a number of these frames in a line, the ventilating thereof being effected by
lifting one or both sides of the hinged frame and supporting it at the desired height
by a stake or a rack.
The entire hot-bed or part of it may be easily removed from one part of the
ground to another without feaving any trace and a great number of frames when not
used can be easily piled or stacked up in a comparatively small space.
A great advantage of this system of hot-bed is that it obviates the necessity of
constructing frame supporting sides in the ground as is the case with the employment
of the ordinary frames.

Improvements in Hot-bed and similar Frames.
1, LOUIS BOULAT of Troyes in the Republic of France, Gardener, do hereby
is to be
declare the nature of this invention and in what manner the same
performed, to be particularly described and ascertained in and by the following
statement :-
The improved hot-bed frame with two slopes which is the object of the present
application for a. patent is represented in the accompanying drawings, in which

page_text: Fig. 4 a similar view of CD:
Figs. 5, 6, 7, 8 and 9 are views of details.
On examining these figures one sees that this system of hot-beds with double
slopes is formed by the jointed union of two simple frames M N respectively
formed as follows ;-
a is a strip or bar of iron fastened to the upper part of the frame by an angle
iron 6 Figs. 2 and 5 rivetted to it and to which are secured the inverted T irons d
in which the glass is set; these are fastened at the corners by a corner piece of
iron rivetted to the T rods d as shown, in Figs. 1 and 5.
Beneath the angle bar 6 a piece of bevelled wood g is fixed forming a support
for the frame, and which is fixed to the bar a by screws as Figs. 3 and 5 show.
This piece of wood g can be replaced by an iron plate bent to the form g¹ (Fig. 6)
the said iron plate being rivetted to the piece A; and its base which forms a flat
part cannot penetrate into the ground on which it rests.
The iron strip or bar a and the angle iron b may be replaced by a single piece
of iron has shown in Fig. 7, which has the advantage of considerably diminishing
the weight of the frame.
The panes of glass rest on the iron work for holding them and butt against
the angle bar 6 which is very solid and not likely to break and does not require
filling up with patty.
The iron handles n are so placed as to enable the frame to be easily moved;
these handles are fixed by their extended ends beneath the angle iron 6 which
renders them much stronger than merely rivetting on top would.
Some projections m fixed in the same way as the handles n are intended to
prevent the frames from lying flat one on the other when they are being removed
or put away thus preventing the glass of the frame from getting broken.
The ridge piece F (Fig. 8) is supported at the junction of the two pairs of
frames by a wooden support P furnished with a sole plate p resting on the ground;
the top p² of the support P is furnished in the direction of the longitudinal axis
of frames, with a metal blade p³ the aim of which is to permit the rotation of the
latter when being opened.
Fig. 9 shows the entire support P in perspective. As for the joints or hinges
which unite the two frames M N at the ridge piece I prefer them to be constructed
of a simple ligature or coil of galvanised iron wire; they may also be constructed
of ordinary strong rivetted hinges which unite the two frames.
Each of the plane frames M N is in the inclined position of the side of a roof
glazed in two slopes the ridge piece of which is represented by the edge of the
joints or hinges and the length of which may be increased at the cultivator's
pleasure according as he may place a smaller or greater number of pairs of frames
in juxtaposition.
The kind of bot-house formed by the union of these frames is easy of access
and easily ventilated because it suffices to raise the frame from the bottom upwards
and by regulating the opening by means either of a rack or of a toothed bar on
which the bottom of the frame is made to rest.
Each part of the frame can without inconvenience fall back upon the part of the
frame of the opposite side, and can be put into working order without fixing or
setting which permits of their being removed from one garden to another without
any previous work on the spot which they ought to occupy and without leaving any
traces on that from which they are removed.
Being able to be folded one over the other by turning round their hinges, these
frames are easily removed and they can be warehoused in a small space in the open
air in high piles.
This system of frames has another great advantage in the saving of boxes required
by ordinary frames.

page_text: 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 ;-
Hot-bed frames made of metal with double slopes formed by the union by hinges
of two plane frames M. N respectively constructed of a number of bars angles and
inverted tees such as a band d which latter support the glass forming the covering
or roof the said frames being centrally supported at the intersection of two pairs of
frames by a support such as P. which rests simply on the ground the frames being
adapted to be folded one over the other when being removed or warehoused without
fear of the glass being broken by the arrangement of the projections M and of the
handles N the whole substantially as described and illustrated in the accompanying
drawings.
