PROVISIONAL SPECIFICATION.
Improvements in Machines for Rolling and Twisting Tobacco.
I, CHARLES HENRY ANDREW, of 20, Waterloo Road, Stockport, in the County of
Chester, Engineer, do hereby declare the nature of this invention to be as follows:-
This invention relates to that type of machines wherein the tobacco is rolled and
twisted by means of three rollers two of which have sectional surfaces adapted to slide
longitudinally.
The object of my invention is to provide a combination of rollers with sectional
longitudinal sliding surfaces, which centralizes the pressure thereby exerted upon
the tobacco and thus compresses it much harder in the process of rolling and
twisting, than heretofore has been the case.
To this end I employ four rollers in lieu of three as formerly, which I arrange in
a circle at equal distances apart from each other. The said four rollers I set slightly
at an angle to each other so as to compress the tobacco gradually, i.e. at the feeding
end the said rollers are a little further apart from each other than at the delivery
end. Two or more of the said rollers are rendered relatively adjustable to suit
various thickness of twist to be produced and are suitably placed under the influence
of strong springs to compensate for hard substances which might be in the tobacco
or for overfeeding the same and thus prevent breakages.

Improvements in Machines for Rolling and Twisting Tobacco.
I, CHARLES HENRY ANDREW, of 20, Waterloo Road, Stockport, in the County of
Chester, Engineer, 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 that type of machines wherein the tobacco is rolled and
twisted by means of three rollers which have sectional surfaces adapted to slide
longitudinally.
The object of my invention is to provide a combination of rollers with sectional
longitudinal sliding surfaces, which centralizes the pressure thereby exerted upon the
tobacco and thus compresses it much harder in the process of rolling and twisting,
than heretofore has been the case.
And in order that my invention may be more fully understood I have caused to be

page_text: appended hereunto two sheets of drawings marked with letters of reference indicating
like parts in the various figures, Fig. 1, Sheet I, being a side view, Fig. 2 a plan,
Fig. 3 a cross section and Fig. 4 an end view: Figs. 5 & 6, Sheet II, are diagrams
of the rollers.
a is the frame of the machine, b, b', 62, 63, are the rollers by which the tobacco is
rolled and twisted, c the feeding table, d the tobacco, e the covering leaf.
In the drawing all the rollers are shown as provided with sectional surfaces whereas
in some cases two of the rollers may be formed plain.
In carrying out my invention and referring to the figures generally, in lieu of
rolling and twisting the tobacco by means of three rollers as formerly, I employ four
rollers b, 61, 62, 63 in a circle at equal distances apart from each other, the side
rollers b, 62 being in a horizontal and the top and bottom rollers 6', 63 in a vertical
plane.
To permit of producing various thicknesses of rolled or twisted tobacco two or more
of the said rollers are rendered relatively adjustable, in the present instance the side
rollers b, 62, by mounting their ends each in a disc f rendered rotary adjustable upon
the sides g, g of the brackets g', g', which are hinged to a shaft h carried by a semi-
circular bracket i, secured to the frame a of the inachine.
The bottom roller 63 is mounted in two brackets k, k, secured to the roller
bracket g, g
In order to compensate for hard substances which might be in the tobacco or
against overfeeding the tobacco one or more of the rollers 6, 61, 62, 63 may be placed
under the influence of a spring in the present instance the top and side rollers b¹ & b²
respectively, the ends of the top roller b¹ being mounted in blocks guided in the
sides of the brackets and acted upon by the springs (2 whilst the sides g of one of the
brackets gabuts against pins m placed under the influence of springs employed
inside the boss a' of the frame a.
The bracket is hinged to the pedestal n, bolted to the semi circular bracket i
and when it is desired to bring the roller bout of use it can be thrown back as shown
in dotted lines Fig. 4, whilst when in use, secured in its position by means of the
clamping lever o which is hinged to the bracket o¹ on the shaft h and has at its upper
ends screwed studs of adapted to engage between lugs la formed on the bracket and
be secured thereto by means of the nuts o*.
The said rollers are set at an angle to each other so as to compress the tobacco
gradually, i.e. the periphery of the rollers at the feeding end being a little further
apart from each other than at the delivery end.
This effect may be obtained in various ways, as shown in Sheet II, for instance the
rollers and their segments may be formed conical and with their axis mounted at an
angle to each other as shown in Fig. 5, and the distance at the feeding end varied by
changing the roller segments, see dotted lines, or the rollers and their segments may
be formed principally cylindrical and their axis mounted parallel to each other, as
shown in Fig. 6, and the distance at the feeding end also be varied by changing the
roller segments, see dotted lines.
The rollers b, b', 62, 63 are all geared up as shown in Fig. 4, Sheet I, and the tobacco
after having been fed from the feeding table c between the rollers and compressed
thereby, is wrapped by the covering leaf e in the usual way and afterwards fabric p
in tape form fed around the tobacco by means of a roller q placed under the influence
of springs r, r, which roller retains the fabric at the required tension, the covering
leaf may however be put on afterwards.
The said fabric serves to prevent the compressed tobacco when leaving the rollers
from expanding and thus retain it in a high state of compression.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim, is :-
In machines for rolling and twisting tobacco, the use of four twisting and

apart from each other, all substantially as and for the purpose set forth.
