PROVISIONAL SPECIFICATION left by the said William John Lemon at the
Office of the Commissioners of Patents on the 4th December 1876.
WILLIAM JOHN LEMON; of Enniskillen, in the County of Fermanagh, Ireland.
"IMPROVEMENTS IN THE MANUFACTURE OF TOBACCO, AND IN THE MACHINERY OR
APPARATUS EMPLOYED THEREFOR."
This Invention relates, firstly, to the manufacture of roll or coil tobacco with a
false core of peculiar construction on which the tobacco is first rolled; and, secondly,
to improvements in the construction of machinery or apparatus for steaming and
pressing such tobacco.
My new or improved false core is constructed of a hollow cylinder of suitable
thin sheet metal, in which I place one or two metallic or wood cylinders.
My improvements in the machinery for steaming and pressing the tobacco consist
in connecting the upper steam chamber by means of a cross bead and guides to a
horizontal bar, through which passes a screw which may be driven in any suitable
manner, so as to raise and lower the upper steam chamber. The said screw and
cross bar also serve to raise the ring or plate of the lower steam chambers by means
of pins or studs of the proper length passing through the lower chamber.
I also employ a metallic ring or rings which is or are placed between the press
plates; within these rings I fit a ring of thin sheet metal, by which means I am
enabled to produce coil or roll tobacco with clean edges, which require no subsequent
trimming.
The employment of the said rings in combination with the herein-before described
false cores enables me to dispense with the central holes in the present press plates.
The berein-before described false core may or may not be left in the roll or coil of
tobacco.

page_text: Figure 1 is a front elevation of the apparatus for steaming and pressing roll or
coil tobacco, the apparatus being shewn closed or screwed down; Figure 2 is a similar
view, shewing the upper heater or steam chamber raised.
In these Figures a is the upper or steam chamber bolted or otherwise suitably
fastened to the cross head b connected to the upper ends of the vertical guides or
bars c, c; these bars c being connected at their lower ends to the horizontal bar d,
through which works the screw e having the cog wheel f at its lower end, such cog
wheelf being operated by a worm or cog wheel driven by hand or power; g is the
removeable steam chamber or heater, fastened in any suitable manner to the lower
heater h fixed on the bench or table i; j is the rising-and-falling ring shewn in
dotted lines; l, k, are the rods or bars fixed to the under side of the ringj, the said
rods or bars k, l, passing through holes in the lower chamber or heater h and bench
or table . The moveable chamber or heater g is shewn in detached enlarged view
in elevation at Figure 5, and plan Figure 9, while Figure 6 is a vertical section of
the same. This heater is formed of a double cylinder of any suitable metal or
metals, but preferably of malleable iron or steel; the space between the two
chambers forms a steam space and allows of the tobacco being heated or steamed
more equally and thoroughly than by the ordinary method of top and bottom
heaters only. The chamber g may be made of any other suitable shape than that
shewn.
Figures 7 and 8 are detached enlarged views of the ordinary heaters a which I
use in combination with the improved heater g.
The operation of the apparatus or machine is as follows:-The upper heater a
being raised, as shewn in Figure 2, the tobacco is placed in the chamberg and the

page_text: screw e is set in motion, thereby bringing down the upper heater a into the position
shewn in Figure 1. When the tobacco is sufficiently pressed and heated the motion
of the screw is reversed, so as to raise the heater a; and when the horizontal bar d
comes in contact with the rods or bars h, k, it also raises these rods or bars, and
thereby the ring j, which forces the tobacco upwards out of the cylinder g, so as to
allow of its being easily removed.
This machine may, if required, be employed for simply setting and preparing the
tobacco in the cylinder or heater g, which may then be lifted off and placed in a
hydraulic press, as shewn in Figure 3, the heater shewn in Figure 7 being employed
to press the tobacco.
In Figure 3 it will be seen that a number of the improved heaters or chambers g
are arranged on steam shelves with the ordinary top heaters a, steam being conveyed
thereto in all cases by. means of flexible pipes, or by any other suitable known
means.
Figure 4 shews an arrangement of using the improved cylinder heater g in
combination with double heaters, the cylinders g being built up one above the other,
with the double heaters placed between them; Figure 8 is a detached enlarged view
of one of these double heaters.
Figure 10 is a plan; Figure 11, an elevation; and Figure 12, a vertical section
of my new or improved false core employed in the manufacture of roll or coil
tobacco; is a light metallic cylinder or case in which fit the two wooden
cylinders m, m; n is a hole through the axis of the cylinders, or the cylinders may
be made solid; Figures 13, 14, and 15, are similar views to Figures 10, 11, and 12,
except that only one wooden cylinder or block is employed instead of two.
Figures 16, 17, and 18, shew in plan, elevation, and section respectively, another
construction of false core consisting of two metallic cases m, m, one fitting insido
the other; m, n, flanges on the ends of the cases m, m, but these flanges may be
dispensed with.
Although in the Drawing I have shown my new or improved. false cores
cylindrical in form it, will be understood that they may be inade of any other
suitable form.
The employment of these new or improved false cores in the manufacture of roll
or coil tobacco enables me to dispense with, and thus avoid the waste of the present
unsaleable corc. In using these cores they are opened out to the width of the
tobacco before it is pressed, the tobacco is rolled on the core, and as the pressing
operation takes place the inner block (or blocks) or the inner case slides in the outer
case, the length of which is equal to the height of the roll when finished.
To enable me to avoid the waste and dispense with the labour of trimming the
ragged edge of coil tobacco when the ordinary press plates are used I employ a light
metallic ring o, Figure 19, encircled by two strong rings 1, 2, together equal in
beight to the inner ring o; or I may employ an inner ring o, Figure 20, encircled
by one heavy ring only. These rings are placed between the ordinary press
plates.
Having thus described the nature of my said Invention, and the best means with
which I am acquainted for carrying the same into effect, I wish it to be understood
that I do not confine myself to the precise details herein laid down and shewn in
the Drawing, as the same may be varied without departing from the peculiar
character of my Invention, but what I do claim is,―
Firstly. The method of and arrangement for putting the pressure on the top
heater and the employment of the rising-and-falling ring for raising the pressed
material out of the moveable heater when the top heater is raised in the manner
described and shewn in Figures 1 and 2 of the accompanying Drawing.
Secondly. The construction and employment of a double moveable heater so as to
form a steam chamber, substantially as and for the purposes herein-before described
and shewn in Figures 3, 4, 5, 6, and 9 of the accompanying Drawing.
Thirdly. The maufacture of roll or coil tobacco with a false core, as and for the
purposes herein-before described.

page_text: Fourthly. The construction and employment of the false cores herein-before
described and shewn in Figures 10, 11, 12, 13, 14, 15, 16, 17, and 18 of the accom-
panying Drawing.
Fifthly. The construction and employment of the rings to be placed between the
ordinary press plates, substantially as and for the purposes herein-before described
and represented in Figures 19 and 20 of the accompanying Drawing.
In witness whereof, I, the said William John Lemon, have hereto set my
hand and seal, this Thirty-first day of May, in the year of our Lord One
thousand eight hundred and seventy-seven.
