TRUVIDIONAL DIBUIE RATIOA
Improvements in Machines for Compressing and Cutting Leaf or
Cake Tobacco.
I CHARLES JAMES Fox Millwright and Engineer of 61 and 65 Kings Cross Road
St. Pancras in the County of Middlesex do hereby declare the nature of this invention
to be as follows:-
This invention relates to improvements in machine for compressing and cutting leaf
or cake tobacco.
The machines now generally used for that purpose consist with other mechanical
arrangements in the use of an iron wheel or drum geared on its periphery with
wood upon which the tobacco is pressed and drawn forward towards the knife and
the tobacco cut to the degree of fineness required the wood part of the drum is
thus gradually cut away or otherwise injured and requires frequent renewal of the
parts so cut away or injured and this is a costly and troublesome operation.
My present invention has for its object the more perfect method of compressing
and cutting the tobacco also to avoid in a great measure the so frequent renewal
of the roll or block upon which the tobacco is cut.
For the purpose of carrying out my said invention I place two series of rolls
fluted or plain (or both) in such numbers as are most suitable one train of rolls
at top and one train of rolls under having an inclined space between them at such an
angle as will ensure a gradual and uniform pressure upon the tobacco which is
drawn forward to the cutting knife and is cut upon a suitable flexible or other
material roll most advantageous for the purpose for instance such as vulcanite or
like material or compounds.
The upper series of rolls are mounted in a metal frame adjustable as required
by means of movable levers or other convenient means so that the dead weight of
such frame and rollers bears on the tobacco and compresses same while being fed
forward to the knife-such adjustment also allowing the two series of rolls to be
moved apart for putting in the tobacco at starting.
The knife is adjusted and actuated in any well known or convenient manner and
the series of feed and compressing rolls are also actuated by the well known ratchet
and wheel motion to give the desired intermittent feed motion or in any other
suitable manner.

Improvements in Machines for Compressing and Cutting Leaf or
Cake Tobacco.
I CHARLES JAMES Fox Millwright and Engineer of 61 and 65 Kings Cross Road
St. Pancras London in the County of Middlesex 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 improvements in machines for compressing and cutting
leaf or cake tobacco and has for its object the compressing and cutting of the various
classes of tobacco (which require cutting in a simpler more regular and consequently
more perfect manner than by the methods and machinery hitherto used and consists
in the construction and arrangement of a tobacco cutting machine in which the leaf
or other tobacco received into a trough or box is drawn forward and submitted to

page_text: a yiolding pressure by and between two series of rollers either fluted roughened
plain or any or all of them which convey it to the mouthpiece and it is there cut
to the required degree of fineness.
The machines now in use are of various constructions but the machine now most
generally used for tobacco cutting purposes consists with other mechanical arrange-
ments in the use of an iron wheel or drum geared on its periphery with wood upon
which the tobacco is pressed and drawn forward towards the knife and the tobacco cut
to the degree of fineness required the wood part of the drum is thus gradually cut
away or otherwise injured and requires frequent renewal of the parts so cut away or
injured and this is a costly and troublesome operation. Moreover the tobacco is both
compressed and cut upon the same roller or drum which is obviated by my present
invention.
My present invention has for its object the more perfect compressing and cutting
the tobacco also to avoid in a great measure the so frequent renewal of the roll or
block upon which the tobacco is cut.
For the purpose of carrying out my said invention I place two series of rolls fluted
or plain (or both) in such numbers as are most suitable one train of rolls at top and
one train
rolls underneath having an inclined space between them at such an angle
as will ensure a gradual and uniform pressure upon the tobacco which is drawn
forward to the cutting knife and is cut upon a solid roll of suitable flexible material
most advantageous for the purpose for instance such as flexible vulcanite or the like
material or compounds.
The upper series of rollers are mounted in a metal frame adjustable as required by
means of movable levers or other convenient means so that the dead weight of such
frame and rollers bears on the tobacco and compresses same while being fed forward
to the knife-such adjustment also allowing the two series of rolls to be moved apart
for putting the tobacco therein between at starting.
The knife is adjusted and actuated in any well known or convenient manner and
the two series of feed and compressing rolls are also actuated by the well known
ratchet and wheel or equivalent motion to give the desired intermittent feed motion
or in any other suitable manner.
And in order that my said invention may be the more easily understood and readily
carried into practice I will now proceed to further describe same by the aid of
the accompanying drawings reference being had to the letters and figures marked
thereon.
Figure 1 is a plan or top view of my machine for compressing and cutting tobacco
without the connecting rod and with shaft and bearings shown in section.
Figure 2 is a side elevation of the machine showing the knife back shaft adjusting
screw worm and wheels for feed rolls and worm and wheel for raising the weights
when required.
Figure 3 is a front elevation with the carriage of swan neck removed and Figure 4
is a longitudinal section through the dotted line on Figure 1.
In each Figure the same letters of reference indicate similar and corresponding
parts of the machine throughout.
A A base of machine.
BB B carriage frames or standards bolted to base plate.
Croll of solid india rubber vulcanite or other suitable flexible material upon which
the tobacco is cut such roll being mounted upon and revolved by a spindle and toothed
wheel thercon (not shown).
D D D lower train of feed rollers.
EE E upper train of compressing feed rollers.
FF movable frames for the top train of rollers and upon which the top part of the
mouthpiece is fixed.
G G lovers for raising the movable blocks and for carrying the weights.
HH links for connecting levers to movable frames.
I weights for compressing.
Jworm and wheels for raising frames and top train of rollers E E E.

page_text: I wish it to be understood that I do not intend to confine myself to the precise
details hereinbefore described as the same may be varied without departing from
the nature of my said invention neither do I confine myself to any number of
rollers D D D and E E E as the number thereof respectively may be varied if desired
and as found suitable.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed 1 declare that what I
claim is
:-
1. In machines for compressing and cutting tobacco the use and application under
the tobacco of a series of rollers such as D D D arranged to act substantially in
the manner and for the purposes hereinbefore described and illustrated in the
drawings hereunto annexed.
2. In tobacco cutting machines of the character herein before set forth the use
and application of a solid roller C of suitable flexible material in combination and
acting in conjunction with top and bottom series of rollers such as D D D and E EE
substantially in the manner and for the purposes herein before described and illus-
trated in the drawings hereunto annexed.
