PROVISIONAL DITIVATION
Improvements in or applicable to the purposes of Forced Draft,
Heating Air, and the like.
I, Sir CHARLES STEWART FORBES, Baronet, of Castle Newe, Strathdon, Aberdeen-
shire, N.B., Gentleman, do hereby declare the nature of this invention to be as
follows:-
My invention consists in improvements in or applicable to the purposes of
forced draft, heating air, and the like, and is carried out as follows:-
In connection with the condensation of steam vapour and for similar purposes
I employ gauze plates or thin perforated laminae each plate being separated from
the other when required by a washer, ring, or the like of soft metal, rubber, rubber
or asbestos cloth, or other suitable material, the whole being held together by
tie bolts passing through end plates or covers having gills or not and fitted with
an inlet and outlet port or ports.
The gauze plates, laminae, or equivalent, project beyond the washers for a
greater or less distance, and in cases wherein the circulation of the air at ordinary
pressure is insufficient to produce the desired cooling or condensing effect the
apparatus described is usually placed in a casing of metal, or the like, and air
blown or sucked through by means of a fan.
My present invention relates more particularly to the utilization of the warmed
or heated air for the purpose of forced draft for heating or warming. To this end
I may employ a pump fan or similar means for forcing air through the projecting
leaves, laminae, or the like of condensers, the air after heating being conducted
to the boiler or other furnace for the purpose of aiding combustion, or
employed for the purpose of warming drying or the like.

Improvements in or applicable to the purposes of Forced Draft,
Heating Air, and the like.
I, Sir CHARLES STEWART FORBES, Baronet, of Castle Newe, Strathdon, Aberdeen.
shire, Gentleman, 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 consists in "Improvements in or applicable to the purposes of forced
draft heating air and the like" and is carried out as follows;-In connection

page_text: ]
with the condensation of steam, vapour, and for similar purposes 1 employ gauze
plates or thin perforated laminae each plate being separated from the other when
required by a washer, ring, or the like of soft metal, rubber, rubber or asbestos
cloth, or other suitable material, the whole being held together by tie bolts pass-
ing through end plates or covers having gills or not and fitted with an inlet and
outlet port, or ports,
The gauze plates laminae or equivalent project beyond the washers for a greater
or less distance, and in cases wherein the circulation of the air, at ordinary pressure
is insuflicient to produce the desired cooling or condensing effect the apparatus
described is usually placed in a casing of metal, or the like, and air blown or
sucked through by means of a fan.
My present invention relates more particularly to the utilization of the warmed
or heated air for the purpose of forced draft for heating or warming. To this end
I may employ a pump, fan or similar means for forcing air through the project-
ing leaves laminne or the like of condensers. for the purpose of warming, drying,
or the like.
The application of my invention will be more clearly understood by reference
to the drawing in which:-
Fig. 1, is a sectional view shewing apparatus arranged for drying.
Fig. 2 shews an arrangement suited for forcing heated air for drying, warming,
or like purposes.
Fig. 3 shews a condenser combined with a blowing engine.
In a former Specification of Letters Patent No. 3027, 1897, I have described
a special form of condenser in which a series of sheets, discs, or other suitably
shaped pieces of metal or metallic gauze separated by packing rings of soft metal.
rubber or similar material are held by tie bolts between metallic end plates, the
gauze leaves or perforated plates projecting to a greater or less distance beyond the
packing rings for the purpose of radiating the heat of the steam or vapour pass
ing through the condenser.
My present invention relates to the utilization of the heated air thus radiated for
drying substances or materials or warming the air of factories, workshops, dwell-
ings, or the like by the means and in the manner hereinafter described.
In one
application see Fig. 1, I may place condensing apparatus of the type referred to or
a series of such 1, to which steam or heated vapour, is conducted as from an adjacent
factory, boiling house, or the like by the pipe 2, in the base of the room, warehouse
or dwelling. 1, Fig. 1, shews such a condenser placed in the basement of a store
in which any type of materials or goods 3, may be suspended packed or spread
out. I employ a fan 4. mounted in the ceiling, sidewall, or in any other suitable
position the fan being so constructed as to exhaust or pull the air through the rooms
in which the goods are stored. It will be understood that the outlet pipe 5, con-
veying the water formed by condensation may be conducted to a hot well 6, or the
like and be used over again for getting steam, or other purposes. I may if
required mount one or more than condenser in the various floors the water condensed
being conducted to a common hot well. In Fig. 2, I have shewn a condenser con-
structed in the manner described but mounted within a metallic shroud or case, a
exhausting fan being bolted to one end of the case, the opposite end being bolted
to the wall in which an aperture is left. It will be understood that upon starting
the fan the cold air from without is pulled through the projecting leaves, laminae,
or plates, the air being warmed by the heat rudiated therefrom. It is then forced
through the building to be warned. I may in some cases employ a pump or
blowing engine 4, as shown in Fig. 3, if more convenient, or 1 may use an equiva
lent device suited for delivering the heated air at a pressure suited for forced
drafi.
I lay no claim to the construction of the condensers referred to herein, and
employed for the purposes of warming drying, and the like. There are cases in
which I am able to warm buildings or dry materials therein by simply placing

page_text: the condensing apparatus in suitable positions without employing mechanical means
for inducing draft.
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:
or like
1. For the purpose of heating air for drying goods warming buildings
purposes, the combination and use of condensing apparatus in which air is heated
by being pulled or forced through or between the extremities of gauze shecis,
perforated metallic leaves or laminae packed arranged and operating in the way
and manner shewn.
2. For the purposes of producing heated forced draft, ventilating, warming,
drying goods or the like the use and employment of a condenser or a series of such
operating for the purposes described combined with a fan, pump, blowing engine,
or like device and enclosed in a case or shrouding.
