County of Middlesex, Tobacco Manufacturer, for the Invention of "A
MACHINE OR ADRATATTO FOR COrzna Han
PROVISIONAL SPECIFICATION left by the said John Roberts, at the
Office of the Commissioners of Patents, with his Petition, on. tho
22nd November 1855.
I, JOHN ROBERTS, jun', of Whitechapel Road, in the County of Middlesex,
Tobacco. Manufacturer; do hereby declare the nature of the said Invention
for "A MACHINE OR APPARATUS. FOR COOLING TOBACCO DURING THE PROCESS OF
MANUFACTURE" to be as follows (that is to say):
My Invention, which has for its object the more effectually and expeditiously
cooling of tobacco than by the method at present employed, consists in the
mechanical, construction and arrangement of a machine or apparatus by which
the tobacco (taken.in a heated state from the drying cylinders or chambers
subsequently to the steaming process) is: submitted to a continuous stream or
current of cold air; to effect which object, I cause an open receptacle of any
suitable form to be mounted upon a frame or stand of any convenient height,
and a partition of wire gauze to be placed horizontally within the said recep-

page_text: tacle for the tobacco to be placed upon, leaving between the bottom of the
receptacle and the wirepartition a space or passage to enable the cold air
to circulate freely through the tobacco; immediately beneath and in connection
with the receptacle I place a common blowing fan, which is caused to revolve
rapidly within a vertical case by the aid of multiplying wheels and strap gear
driven by steam or any other motive power, the effect of which, through the
interposition of a spreader for diffusing the draught or current of cold air
superficially over the tobacco situated above it, allows of greater quantity of
tobacco during the process of manufacture being cooled in less time than by
the present custom of exposing it in open trays or receivers to the common
atmosphero.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said John Roberts in the Great Seal Patent Office on the
22nd May 1856.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
ROBERTS, junior, of Whitechapel Road, in the County of Middlesex, Tobacco
Manufacturor, send greeting.
:
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the. Twenty-second day of November, in the year of our
Lord One thousand eight hundred and fifty-five, in the nineteenth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said John Roberts, junior, Her special licence that I, the said John Roberts,
junior, my executors, administrators, and assigns, or such others as I, the said
John Roberts, junior, my executors, administrators, and assigns, should at any
time agree with, and no others, from time to time and at all times thereafter
during the term therein expressed, should and lawfully might make, use,
exercise, and vend, within the United Kingdom of Great Britain and Ireland,
the Channel Islands, and Isle of Man, an Invention for "A MACHINE OR
APPARATUS POR COOLING TOBACCO DURING THE PROCESS OF MANUFACTURE," upon the
condition (amongst others) that I, the said John Roberts, junior, my execu-
tors or administrators, by an instrument in writing under my, or their, or
one of their hands and seals, should particularly describe and ascertain the
nature of the said Invention, and in what manner the same was to be per-
formed, and cause the same to be filed in the Great Seal Patent Office
within six calendar months next and immediately after the date of the said
Letters Patent.

page_text: NOW KNOW YE, that I, the said John Roberts, junior, do hereby declare
the nature of the said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement, reference being had to the accompanying Drawings (that is
to say):-
My Invention, which has for its object the more effectually and expeditiously
cooling of tobacco than by the method at present employed, consists in the
mechanical construction and arrangement of a machine or apparatus by which
the tobacco (taken in a heated state from the steam chamber or pan) is sub-
mitted to a continuous stream or current of cold air; to effect this object, I
cause an open receptacle of any suitable form to be mounted upon a frame or
standard of any convenient height, and a partition of wire gauze to be placed
horizontally within the said receptacle for the tobacco to be placed upon,
leaving between the bottom of the receptacle and the wire partition a space or
passage to enable the cold air to circulate freely through the tobacco. Imme-
diately beneath and in connection with the receptacle I place a common
blowing fan, which is caused to revolve rapidly within a vertical case by the aid
of multiplying wheels and strap gear driven by steam or any other motive
power, the effect of which, through the interposition of a spreader for diffusing
the draught or current of cold air superficially over the tobacco situated above
it, allows of greater quantity of tobacco during the process of manufacture
-being cooled in less time than by the present custom of exposing it in open
trays or, receivers to the common atmosphere.
But in order that this my said Invention may be more fully understood and
readily carried into effect, I now proceed to describe it by the aid of the
accompanying Drawings, reference being had to the letters and figures thereon
marked (that is to say):
Fig. 1 represents a front elevation of my machine or apparatus for cooling
tobacco during the process of manufacture; Fig. 2, a side elevation; Fig. 3, a
transverse vertical section, taken through the dotted line in Fig. 2; Fig. 4,
a longitudinal section, taken through the dotted line in Fig. 1; Fig. 5, a top or
plan view, with the wire gauze partly removed; and Fig. 6, a corresponding
view, with the tray or receptacle removed. In each Figure the same letters
of reference denote similar corresponding parts.
A, A, frame or standard; B, B, tray or receptacle; C, C, bracket standards
or columns for supporting the tray or receptacle; D, D, fan wheel or blower;
E, E, vertical case in which the said blowing fan revolves; F, F, tube passing
through the lower portion of the tray or receptacle; G, G, perforated plate or
spreader, supported on feet for the purpose of diffusing the draught; H, I,

page_text: space or passage for enabling the cold air to circulate freely through the tobacco
in the direction of the arrows; I, I, wire gauze or peforated partition upon
which the tobacco is placed; J, J, frame or stretcher upon which the gauze or
perforated partition is mounted, for the purpose of being readily removed from
the receptacle when necessary; K, K, driving shaft; L, L, plumber block
bearings; M and M', strap wheel and pulley; N, N, driving band or strap;
O, O, forked-head sliding bar, for throwing the shaft in or out of gear with the
engine; P, P, slip bearings in which the said rod works; Q, Q, grooved wheel,
firmly keyed upon the driving shaft, for giving rotary motion to the blower
through the medium of the intermediate multiplying straps and pulley wheels
R and S; T, T, pivot bearings, bolted to the side flanges of the blowing fan,
in which the shaft or axis of the fan revolves; U, tightening screw; V, V, con-
centric openings in the sides of the case for the admission of air to the blowing
fan; W, W, bolts and nuts for securing the framing to the floor.
Having now fully described the nature of this my said Invention, and the
manner in which the same is to be performed, I would have it clearly under-
stood that I do not intend to confine myself to the precise details herein-before
described, as the same might be varied without departing from the general
principle of this my said Invention, or employed for other similar purposes,
such as cooling feathers, coffee, or otherwise, or a V or other fan wheel in
place of the common one, as represented, may be employed; but that which I
do claim as new and of my said Invention is, the general construction and
arrangement of the machinery or apparatus in the manner and for the purposes
herein-before set forth and described.
In witness whereof, I, the said John Roberts, junior, have hereunto set
my hand and seal, this Twenty-first day of May, in the year of our
Lord One thousand eight hundred and fifty-six.
