PROVISIONAL SPECIFICATION.
Improvements in Heating and Humidifying Apparatus.
We, WILLIAM HULME, Junior and JAMES HULME both of Moor Nook Sale, in the
County of Chester, Market Gardeners, do hereby declare the nature of this invention
to be as follows:-
The improvements which are the subject of this invention relate to the means for
obtaining a warm humid atmosphere in greenhouses or other structures where such
an atmosphere is necessary, either for the growth of plants, or for the purposes of
manufacture: In this invention we form pipes either of wood, metal or other
suitable material which we place in one or more lengths around the inside of green-
house or other structure : At convenient places in the pipes herein above described
and on the upper tier of such pipes when two or more lengths are employed we
construct an aporture or apertures with walls or sides extending from said pipes so
as to form bottomless troughs: We keep those troughs supplied with hot water by
means of the circulation of water which we cause to pass in a heated state first
through the upper length of pipe and as it cools flowing into the lower set of pipes.
Theso troughs are provided with covers, by which the amount of steam or vapour
passing into the air is regulated: said covers may also be provided with openings for
the like purpose.

COMPLETE SPECIFICATION.
Improvements in Heating and Humidifying Apparatus.
Wo, WILLIAM HULMк, Junior and JAMES HULME, both of Moor Nook Sale, in
the County of Chester, Market Gardeners, do hereby declare the nature of this inven-
tion and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement :-
The improvements which are the subject of this invention relate to the means
employed for obtaining a warm and humid atmosphere in greenhouses or other
structures where such an atmosphere is necessary, in order either to facilitate the
growth of plants or for manufacturing purposes. In this invention we form pipes
either of metal or other suitable material which we place in one or more lengths
around the inside of a greenhouse or other structure: At convenient places in the
pipes herein above described, and on the upper tier of such pipes when two or more
rows of pipes are employed we construct an aperture or apertures with walls or
sides extending from said pipes so as to form bottomless troughs. We keep these
troughs supplied with hot water by means of the circulation of water which we cause
to pass in a heated state first through the upper length or row of pipes and as it
cools flowing into the lower set: These troughs are provided with covers by which
the amount of steam or vapour passing into the air is regulated: said covers may
also be provided with openings for regulating the amount of moisture for the like
purpose: In order more clearly to describe this our invention we have annexed
hereunto a sheet of drawings: in the several views therein shown, similar letters refer
to similar parts: the lengths of pipes b may be made to suit the size of building for
which they may be required: Fig. 1 represents a length formel of several pipes b
in one of which a humidifyer or vaporizer c is constructed by means of an aperture d
formed in upper part of said pipe and surrounded with sides or walls e which thus
form bottomless troughs f: We construct a cover g to fit on said trough so as to be

capable of being wholly or partially removed when required : Fig. 2 represents a
length of piping in which we form a number of divisions for vaporizing. In this
view the trouglis fare constructed as in Fig. 1-Fig. 3 is transverse section of trough
or humidifyer drawn through line A. A. Fig. 4, represents a range of piping in which
one or more humidifyers or vaporizers may be constructed on the upper tier as
shown The heated water is caused to pass along the pipes in the direction indicated
by arrows shown on drawing, by entering at a and flowing towards the outlet at v :
The atmosphere is rendered more or less humid according to the extent the covers g
are opened or removed. Fig. 5 represents plan view of a fixed cover formed so that
the amount of vapour which is allowed to escape from trongh may be regulated by
the slide without removal of cover. Figs. 6 and 7 are respectively a plan view and
Jongitudinal section of a cover formed with a slide theroin: In these views the
slide h may be moved longitudinally by the handle ; working in slot k so as to open
or close the apertures 1, or both cover and slide may be lifted off and removed by
means of said handle j.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what
we claim is
•
A heating and humidifying apparatus which may be employed to obtain a warm
damp atmosphere in a greenhouse or other structure, consisting of one or more troughs
formed in a pipe or pipes with covers for regulating the supply of moisture to tho
atmosphere, in the manner substantially as herein before described and as illustrated.
