PROVISIONAL SPECIFICATION..
Improvements in Apparatus for Breaking Up or Opening Cotton
and other Textile Materials.
ALFRED HITCHON, Machinist, Globe Works, Accrington, do hereby declare
the nature of this invention to be as follows: --
My invention relates to machinery through which cotton or other fibrous material
is passed to be broken up cr opened by same, by means of spiked rollers. Such
spiked rollers are formed in various ways to give the desired form of spike. These
spiked rollers are built up or made by threading and fixing in close contact a number of
star or spike shaped rings sections or segments on a shaft, the ends of the shaft
forming the necks of the roller. The star or spike shaped rings are of equal
diameter and duplicate formation in every respect. By this method, this well
known type of roller is built up to any desired width.
These spiked drawing rollers when placed in the machine are made to run in
pairs, each successive pair being placed at a suitable distance from the preceding
one, and also made to revolve at an accelerated surface speed, the result being
that a certain amount of opening action is imparted to the material passing between
the said rollers. In some cases each roller in any individual pair is made to revolve
at an unequal surface speed to its fellow roller, so that each pair of rollers has or
imparts within itself an opening action, but as each pair of rollers have to do duty
in passing cotton to succeeding pairs the difference in surface speed of the relative
rollers is very limited...
In this my new invention I build up my rollers with star or spiked shaped rings
of specific different diameters in such a manner that a small ring on one roller
intersects with a large ring on its fellow roller. These star or spiked shaped rings
may be threaded on the shaft in repetition order of one or more of large diameter
and then one or more of small diameter, to the full length of the roller.
If desireable, more than two different diameters of star or spike shaped rings may
be used.
By using rollers of this description revolving at constant speeds, I obtain different
surface speeds in the same roller, thereby giving a greater opening or breaking up
power than has been obtained hitherto. The spiked rings of the larger diameter
being placed to intersect with the smaller, a stretching action is obtained between
the points of the alternate large rings in each roller.
Dated this Eleventh day of September 1895.

ALFRED HITCHON Machinist Globe Works Accrington 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 :-
My invention relates to machinery through which cotton or other fibrous

Such spiked rollers are formed in various ways to give the desired form of spike.
The spiked rollers are built up or made by threading and fixing in close contact a
number of star or spike shaped rings sections or segments on a shaft, the ends of
the shaft forming the necks of the roller.
These star or spike shaped rings are of equal diameter and duplicate formation
in every respect.
By this method, this well known type of roller is built up to any desired
width.
These spiked drawing rollers when placed in the machine are made to run in
pairs, each successive pair being placed at a suitable distance from the preceding
one, and also made to revolve at an accelerated surface speed, the result being that
a certain amount of opening action is imparted to the material passing between
the said rollers. In some cases each roller in any individual pair is made to
revolve at an unequal surface speed to its fellow roller, so that each pair of rollers
has or imparts within itself an opening action, but as each pair of rollers
have to do duty in passing cotton to succeeding pairs the difference in surface speed
of the relative rollers is very limited. .
In this my new invention I build up my rollers with star or spiked shaped rings
of different diameters in such a manner that a small ring on one roller intersects
with a large ring on its fellow roller. These star or spiked shaped rings may be
threaded on the shaft in repetition order of one or more of large diameter and then
one or more of small diameter, to the full length of the roller. If desireable,
more than two different diameters of star or spike shaped rings cast in single rings
or two or more may be used.
By using rollers of this description revolving at constant speeds, I obtain
different surface speeds in the same roller, thereby giving a greater opening or
breaking up power than has been obtained hitherto. The spiked rings of the
larger diameter being placed to intersect with the smaller, a stretching action is
obtained between the points of the alternate large rings in each roller.
Such being the nature and object of my invention, I will now make reference
to the accompanying sheet of drawings, which fully illustrates the means I employ
for making the same effectively :-
Fig. 1 represents one pair of rollers made up of the star or spike shaped rings of
varying diameters as described, shewing the long tooth points coming in opposition
to the point of the shorter tooth ring of each roller alternately in rotation
respectively with each tooth in its companion roller.
Fig. 2 is a single pair of rings.
Fig. 3 is an end view of same.
Fig. 4 shows an end view of four pairs of my improved rollers to illustrate how
the long tooth of star wheel rings are placed to intersect with their companion
rings that have the shorter teeth to give the stretching action to the fibrous material
passing between the same.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what I
claim is
Textile fibre drawing or opening rollers having ring or line of spike tooth like
formations of different diameters which are placed to intersect to another ring or
line of teeth on the fellow rollers, to which they are made to revolve in one or more
pairs as described and illustrated by the accompanying sheet of drawings forming
nart of this specification
