page_text: I, THOMAS PUGH RICHARDS, of 3 and 5, Salthouse Lane, in the City of Liverpool,
Engineer, do hereby declare the nature of this invention to be as follows:-
This invention relates to drying closets in which hot dry air is used as a drying
medium.
A drying closet according to this invention consists of a somewhat narrow
chamber or chest of considerable length. The internal sides of said chest have
projecting ledges adapted to support trays upon which the articles to be dried are
laid. The two ends of the chest possess a number of swinging doors, one door being
provided for each pair of tray supporting ledges. The trays are fed into the chest
at one end and are pushed, or travel by mechanical means, to the other end, where
they are removed. I prefer the hot dry air to enter at that end of the chest where the
articles to be dried are removed, and to leave at that end of the chest where
they enter. The hot air supply and exhaust pipes (which may be led down the
sides of the chest) may have a number of ports or apertures corresponding with the
number of tray spaces.
A drying closet constructed as above described may be used for drying various
articles, and is particularly applicable for drying certain varieties of sweetmeats,
and also for drying certain varieties of chemicals and other substances and articles
of manufacture.
I, THOMAS PUGH RICHARDS, of 3 and 5, Salthouse Lane, in the City of Liverpool,
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:―
This invention relates to drying closets in which hot dry air is used as the drying
medium.
In the drawings hereto annexed, there are illustrated a drying closet according
to my invention, and an air heater, for heating the air which is supplied to the
drying closet.
Figure 1 is a side view partly in section, Figure 2 a cross-section, and Figure 3

page_text: a sectional plan, of my improved drying closet. Figure 4 is a view of the air
heater which I prefer to employ.
A drying closet according to this invention consists of a chamber or chest a of
considerable length. The interior of the chest a is divided by the shelves b into
a series of separate chambers. Trays containing the articles to be dried are fed
into the chest at the end a¹ and are pushed, or travel by mechanical means, to the
end a, where they are removed. The two ends of the chest possess a number of
swinging doors c, one door being provided for each tray space in the chest. The
doors c at the entrance end of the chest are arranged to swing inwardly to admit
the trays, whilst the doors c of the exit end are arranged to swing outwardly to
permit of their withdrawal.
The closet a is heated by hot dry air, which is preferably produced by the generator
shewn in Figure 4 and which consists of a chamber d filled with tubes e. Air
is forced by the fan f through the tubes e, whilst steam is circulated through the
chamber by the pines g. The air thus heated passes by the pipe h to the
drving closet. From the pipe h ducts h¹ are led into each tray space in the closet.
After circulating through the tray space the air escapes by the ducts into the
outlet pipe i. The ducts and are separately controlled by dampers k and 7 so
that the passage of hot air through each separate tray space may be controlled
at will.
A drying closet constructed as above described may be used for drying various
articles and is particularly applicable for drying certain varieties of sweetmeats,
and also for drying certain varieties of chemicals, and other substances and articles
of manufacture.
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:-
-
In combination, a closet partitioned by diaphragms or shelves into a series of
chambers, hot air inlet and outlet pipes on the exterior of said chest communicating
by separate ducts with each of said series of chambers. dampers on said ducts, and
swinging doors on said chambers, said doors being arranged to swing inwardly at
the entrance end of the 'chamber, and outwardly at the exit end thereof,
substantially as described.
