PROVISIONAL SPECIFICATION.
Improvements in Stoves for Drying Textile Materials and Fabrics.
We, HUGH WYLIE, Turkey-red Dyer and Printer, of Cordale and Dalquhurn
Works, Renton, in the County of Dumbarton, North Britain, and ROBERT
PATTERSON TORRANCE, of the same works, Engineer, do hereby declare the
nature of this invention to be as follows, that is to say :-
This invention has for its object to secure improved and more regular drying.
and ventilating action and economy of fuel in stoves for drying textile materials
and fabrics, the improvements being advantageously applicable to stoves such
as are employed in Turkey-red and similar works.
In stoves of the kind referred to heat is applied by means of flues at the bottom
of the building, through which flues the fire gases pass from one or more furnaces;
and air heated by the flues ascends through perforated floors and acts on the goods
arranged in flats one over the other, the moisture finally escaping at the top of the
building.
By the present invention, instead of constructing the flues, as heretofore upon
the ground so that a considerable part of the heat is conducted down into the
ground and wasted, they are constructed upon a floor formed by iron plates
supported on girders so as to have an air space beneath them. The floor plates
are perforated excepting at the parts carrying the flues; and the air to be heated
by the flues and to ascend up through the goods is admitted through openings
provided with regulating dampers or valves, into the space below what may be
termed the flue floor. The air thus admitted not only prevents or very much
diminishes the radiation of heat to the ground but also takes up the heat that
would otherwise be radiated or conducted downwards, and consequently causes
considerable economy of fuel. The ascending air is also more uniformly heated
and rendered more uniform in its action, in consequence of being admitted below
the flue floor and being distributed by the perforations in that floor, than it is when
admitted as in existing arrangements into the space immediately over the flues,
or at upper flats.

COMPLETE SPECIFICATION.
Improvements in Stoves for Drying Textile Materials and Fabrics.
We, HUGH WYLIE, Turkey-red Dyer and Printer, of Cordale and Dalquhurn
Works, Renton, in the County of Dumbarton, North Britain, and ROBERT
PATTERSON TORRANCE, of the same works, Engineer, 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, that
is to say :-
This invention has for its object to secure improved and more regular drying
and ventilating action and economy of fuel in stoves for drying textile material

page_text: and fabrics, the improvements being advantageously applicable to stoves such
as are employed in Turkey-red and similar works.
In stoves of the kind referred to, heat is applied by means of flues at the bottom
of the building, through which flues the fire gases pass from one or more furnaces.
By the present invention, instead of constructing the flues, as heretofore upon the
ground so that a considerable part of the heat is conducted down into the ground
and wasted, they are constructed upon a floor formed by iron plates supported
on girders so as to have an air space beneath them. The floor plates are perforated
excepting at the parts carrying the flues; and the air to be heated by the flues
and to ascend up through the goods is admitted through openings provided with
regulating dampers or valves, into the space below what may be termed the flue
floor.
And in order that our said invention and the manner of performing the same
may be properly understood we hereunto append a sheet of explanatory drawings
to be hereinafter referred to and showing in vertical section a simple arrangement
of drying stove as provided with our improved heating apparatus.
As shown in the drawings the drying stove consists of a building, A, having
several flats; and the heating is effected by means of flues in the ground flat.
Fire
gases pass from two furnaces (not shown) along two flues, B, one at each side in
the ground flat of the building, and extending the length of the building. At
the further end the flues, B, are connected by short cross flues indicated by dotted
lines to flues, C, through which the fire gases return to the front, whence
they pass again to the further end by flues, D, finally returning through iron
flues, E, which communicate with a chimney. The flues, B, C, D, E, are
constructed or carried upon a floor, F, formed by iron plates supported on
girders, G, so as to have an air space, H, beneath them. The floor plates, F,
are perforated excepting at the parts carrying the flues, or there may be openings
of any convenient size between the flues; and the air to be heated by the
flues, B, C, D, E, is admitted through grated openings provided with regulating
dampers, or valves, J, into the space, H, below what may be termed the flue
floor, F. The air thus admitted not only prevents or very much diminishes the
radiation of heat to the ground but also takes up the heat that would otherwise
be radiated or conducted downwards and consequently causes considerable economy
of fuel. The ascending air is also more uniformly heated and rendered more
nniform in its action in consequence of being admitted below the flue floor, F,
and being distributed by the perforations or openings in that floor, than it is when
admitted as in existing arrangements through windows, K, into the space, L,
immediately over the flues or by windows, M, into the various flats. The air
heated by the flues ascends through perforated floors, N, and acts on the goods.
suitably arranged in each flat, the moisture finally escaping at the top of the
building, A. If at any time it is desirable to diminish the heat of the air some
cold air can be admitted through the windows, K.
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 :-
In stoves for drying textile materials and fabrics forming an air space beneath
the fire gas flues, and causing the air to be heated to pass through such spaces,
substantially as and for the purposes herein before described.
