THE METHOD OF MAKING A MACHINE FOR DRYING COFFEE, OR BARLEY, OR ANY OTHER GRAIN, PULSE, FRUIT, SEED, AND BERRIES
Year: 1806

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JAMES
HENCKELI, of the City of London, Merchant, send greeting.
WHEREAS His most Excellent Majesty King George the Third did, by
His Letters Patent under the Great Seal of the United Kingdom of Great
Britain and Ireland, bearing date at Westminster, the Twentieth day of
November, in the forty-seventh year of His reign, give and grant unto me,
the said James Heuckell, my exors, adiñiors, and assigns, His especial licence,
full power, sole privilege and authority, that I, the said James Henckell, my
exors, admors, and assigns, during the term of years therein mentioned, should
and lawfully might make, use, exercise, and vend, within England, Wales,.
and the Town of Berwick-upon-Tweed, an Invention communicated to me by
a certain foreigner, of "THE METHOD OF MAKING A MACHINE FOR DRYING COFFEE,
OR BARLEY, OR ANY OTHER GRAIN, PULSE, FRUIT, SEED, AND BERRIES;" in which
said Letters Patent there is contained a proviso, obliging me, the said James
Henckell, by an instrument in writing under my hand and seal, to cause a
particular description of the nature of my said Invention, and in what manner
the same is to be performed, to be inrolled in His Majesty's High Court of
Chancery within six calendar months after the date of the said recited Letters
Patent, as in and by the same (relation being thereunto had) may more fully
and at large appear..

page_text: NOW KNOW YE, that in compnance with the pro
James Henckell, do hereby declare that the said Invention is described in
manner following, that is to say):-
1st. A main axletree, spindle, or shaft, in one piece or more, connected by
one or more coupling boxes, or bolted together with a bearing at or near each
end, and at intermediate distances when wanted, and a squaro to fit the wheel,
or other mechanical contrivanco by which the motion is to be communicator;
and by means of coupling-boxes, or wheels, any number of these machines may
be put in motion by the same power.
2d. Wheels, circles, and arms placed thereon, all or of any them, more or
fewer, in proportion to the length of the bearings, and if required, these may be
strengthened by additional circles, arms, or other supports, at the option of the
Patentee or other person authorised by him, which will be varied in proportion
to the strength of the machinery and the weight to be supported.
3d. Barrels or cages of any shape or dimensions, fastened to any part of
these circles, arms, or other supports, or connected therewith by spindles or
axles, which may be either short bearings or in different lengths, to support a
single barrel or cage, two or more together, or the whole of a row by one piece,
and theso barrels or cages may be strengthened, if required, by inside circles
and supports. The number larger or smaller, as may best suit the situation
wherein the machines are to be placed. They may be made either close or
with apertures to let out the vapour that may arise from the substances
intended to be dried. If close, they must be provided, if necessary, as will
generally be the case, with valves to permit the escape of that vapour; or,
although close in other respects, one aperture or more should be made in the
side, which may give vent to the vapour without letting out the substances
intended to be dried, and there must be an opening or door to each of these
barrels or cages to receive and discharge their contents. The rotatory motion
of the machine, which may be obtained by manual labour, with a winch,
with or without wheels, brasses, or other contrivances usually employed by.
workmen to lessen the resistance, or by water, steam, wind, cattle, or any other
mode that shall be found more convenient, expeditious, or less expensive than
manual labour; this rotatory motion will continually operate in changing the
position of the different particles intended to be dried, and this operation may be
still increased, if required, as likewise the particles be prevented from cohering
by one piece or more of wire or network placed within the barrels or cages, in
the same direction as the shaft, or obliquely, by pins, ledgers, or other stops
fastened on the inside, or by serpentine or winding grooves or ledges calculated
to give an oblique direction to a part or the whole of the substances to be dried.

page_text: And when it shall be found requisite or convenient, a double motion may be
given by additional wheels to the whole, or any part of these barrels or cages,
-one with the main axis and another round their own. It may sometimes
happen that an immediate contact with the barrels or cages would injure the
quality or colour of the article intended to be dried; but this may, in most
if not all case, be prevented by the interposition of other substances which
would not be liable to the same inconvenience. This machine may be adapted
to such a variety of scales, such different degrees of heat, and used for such
different substances, that it is not possible to enumerate the materials, from the
hardest metal to paper, that would, in each of these cases, be the most appro-
priate for the several component parts thereof. These cages or barrels may
likewise operate as sieves, and by placing different wires or other perforated
substances at convenient distances, one within another, they may be made to
produce by the same motion such a number of divisions as shall be wanted.
4th. A fire stove, furnace, or any other means of creating warmth, to give
to the apartment containing the machine the degree of heat that may be
wanted, and where accuracy is required, a thermometer will be useful. When
fire is used for the purpose of obtaining a first motion to the axletree, spindle,
or shaft, that fire may be so contrived or placed as to give to the apartment
containing the machine a part of or all the heat required for the article in-
tended to be dried.
5th. Greater dispatch may be obtained by laying the substances intended to
be dried on one or more platforms, shelves, or troughs, some time before it is
intended that they shall be put into the barrels or cages; and if a little inclined,
the moisture will be the more easily drained from them, or they may have bot-
toms made of wire, or any other perforated substance, with or without a close
bottom underneath. If made to turn on a swivel, the substances to be dried will
be the more easily discharged from a higher to a lower situation; or the same
purpose may be effected by trap doors should these shelves or troughs be
closed by a ledge at the end or side, that ledge may be made to let down, or an
occasional aperture be made therein by means of a sliding door. It may, also,
be adviseable to spread whatever is intended to be dried, before it goes into the
barrels or cages, on the upper surfaces or ceiling of the apartment containing
those barrels or cages or on shelves or troughs placed above it in the manner
already described, as the warmth thereby acquired will curtail the subsequent
operation; or, when different machines are used, the substances to be dried
may be transferred from one barrel or cage to another, as often as shall be
found convenient. And those machines may be so placed that the same fire,
stove, or furnace, may impart different degrees of heat to each.

page_text: 6th. The contrivances already mentioned for the shelves or troughs may
be useful in removing the articles, when dried, to some other place.
In witness whercof, I, the said James Henckell, have hereunto set my
hand and scal, the Fourteenth day of May, in the year of our Lord
One thousand eight hundred and seven.
(L.S.)
AND BE IT REMEMBERED, that on the Fourteenth day of May, in the

said, and all and every thing therein contained and specified, in form above
written. And also the Specification aforesaid was stampt according to the
