I, WALTER THORNTON LINTON, of 18 & 19, Red Lion Square, in the County of
Middlesex, American Merchant, do hereby declare the nature of my invention for
"AN IMPROVED
APPARATUS FOR DRYING PREPARED COCOA NUT AND SIMILAR
COMPOUNDS," and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:~
My invention relates to the construction of an improved apparatus to be used for
drying prepared cocoa-nut, and similar compounds; and is particularly applicable
for drying preparations of cocoa nut compounded under Letters Patent granted to
me, 7th January, 1885, being No 241 of that year; although I would have it
distinctly understood that my invention is not restricted practically to the drying
of the cocoa nut compound described in the specification of the above Letters
Patent, inasmuch as it may be used advantageously for the purpose of drying
similar compounds requiring, for the purpose of efficient desiccation, a treatment
of the kind which a drying apparatus constructed according to my invention is
capable of exerting.
In carrying my invention into practical effect, I provide a drying table heated
by a series of pipes lying immediately under it. These pipes are heated, preferably,
by live steam. This table is fixed at a convenient distance from the floor. The
space under the table is closed in, so as to form a drying chamber, access to which
is provided for by making one side removeable. Through the opening, or door, thus
produced, a drying trolley is introduced into the chamber. The trolley may be a
multiple one, that is, fitted with shelves, one above the other, or may be replaced
by a shelf, or shelves, sliding on suitable supports; and above, the before mentioned
table, I may, when desirable, erect other drying tables.
It is obvious that, according to my invention, the user enjoys two varieties of
applied heat from one source, the one on the drying table, where there would be
free escape for the moisture, and the other in the drying chamber, where the
temperature would be higher, and the escape of the moisture less rapid in conse-
quence of its being confined; although, when desired, the drying chamber may be
fitted with ventilating apparatus, with a view to make the process of drying, going
on therein, proceed under the saine conditions as obtain above the drying table.
In practical use, the wet compound is placed first upon the drying table, and
finished in the chamber, or vice versa, according to whether it is desired to expel
the moisture rapidly, or slowly, at first, This, of course, depends upon the nature

apparatus can be made in series, i.e. tables and chambers side by side, the conditions.
of moisture and temperature obtaining in the latter be capable of regulation as
above described, it is evident that the capabilities of my invention are such as to
be readily utilised as soon as the requirements of the compound to be dried, are
known.
In order that my invention, and the means by which the same can be carried
into successful operation, may be thoroughly understood, I will proceed to describe
the same in detail, referring in so doing to the accompanying drawings, which are
to be taken as part of this specification and read therewith, and in which like parts
are, throughout, marked with the same reference letter.
I would however have it distinctly understood that I do not confine myself to
the precise construction illustrated in the drawings, which are presented only as
showing one application of my invention which I find in practice to be succesful.
From the foregoing explanation of its principles and essential features, it is
evident that the arrangement illustrated is capable of considerable variation, while
still embodying the essence and substance of the invention.
Figs. 1 and 2 are respectively front elevation and plan, shewing my invention
constructed as a three-table-and-chamber-apparatus.
A, A, A, are the tables preferably of sheet iron rivetted to angle irons a, a, a,
which are, in turn, carried by the substructure, B, which may be either of masonry,
timber, or any other suitable material; and either standing independently on the
floor, of the factory, or built into the factory walls.
If it is desired to arrange the drying tables in series one above the other, the
partitions, A¹, and ends of the substructure (if any), would be raised and fitted with
angles to carry the additional tables or rather shelves.
C, C, C, are the chambers between the tables, A, and the factory floor, D. The
areas of these, as well as those of the tables, are decided by the particular require-
ments of the case.
+
E, E, E, are the drying trolleys, dotted in side elevation in Fig. 2, of any
convenient shape and depth. Angles or bars, e, e, may be laid to facilitate their
travelling straight.
In the figure the drying chambers are shown as permanently closed behind, by a
wood back e¹, their fronts are consequently fitted with doors not shewn in the
figures.
The heat required is supplied, preferably by live steam, fed into the main, G,
from which it is conducted into any suitable or convenient type of coil, or gridiron,
pipes, g. 9, g, arranged under the drying tables, A. I do not confine myself to any
particular shape of heating pipe, whether of the gridiron or coil type. In Fig. 2,
the left hand chamber is fitted with a gridiron heater, the pipes of which are
parallel with the front of the apparatus, while those of the heater of the middle
chamber are at right angles with the front.
If preferred, other than pipe heaters may be used, but I illustrate steam pipe
'heaters as the most convenient.
Each heater is, preferably, fitted with its own supply valve, g¹. H is the exhaust
pipe, and, h, the condense.
I do not illustrate any ventilating device to abstract the evaporated vapour from
the chambers, as devices for this purpose are sufficiently well known, as well as the
methods of applying them.
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
1. In an apparatus for drying prepared cocoa nut and similar compounds, the
combination of heater, g, of any convenient type; drying table, A; and drying
chamber, C; the whole substantially as described, with reference to the accom-
nanving figures.

3. In an apparatus for drying prepared cocoa nut and similar compounds, the
combination of heater of any suitable type; drying chamber, C, fitted with shelves

4. The arrangement in series, e.g., side by side, of either of the above defined
combinations, substantially as claimed and described with reference to the accom-
panying figures.
