Improvements in or connected with Machinery or Apparatus for
Preparing for Spinning and Spinning Cotton and other Fibrous
Materials.
I, WILLIAM HENRY RHODES, of 5 Lime Grove, Longsight, in the County of
Lancaster, Machinist, do hereby declare the nature of this invention to be as
follows:-
My invention relates to machinery or apparatus for preparing for spinning and
spinning cotton and other fibrous substances, and consists in arrangements by which
I am enabled to impart additional twist to the sliver, slubbing or roving while
unwinding it from the bobbin or tube upon which it has been wound and thus to
employ a sliver, slabbing, or roving formed with a less amount of twist than is
usually necessary.
In performing my invention I mount the slubbing or roving bobbin, spool or tube
from which the sliver, slubbing or roving is to be unwound upon a fixed peg
projecting from a rail or board. I draw off the sliver, slubbing or roving from one
end of the bobbin, spool or tube upon which it has been wound and upon the said
sliver, slubbing or roving I place a tube through which the sliver, slubbing or
roving passes while being unwound from the bobbin, tube or spool. Upon the
upper end of the tube before mentioned I form or secure an enlarged part or
collar. While the sliver, slubbing or roving is being unwound from the bobbin,
spool or tube, the tube before mentioned will travel around the bobbin, spool or
tube preventing the portion of sliver, slubbing or roving being unwound from passing
into contact with the other portion of the sliver, slubbing or roving upon the bobbin,
tube or spool.
The lower end of the tube before referred to also tends to separate the portion
of the sliver, slubbing or roving being unwound from the other portion of the sliver,
slubbing or roving.
I surround the bobbin spool or tube from which the sliver, slubbing or roving is
being unwound, by a shield or guard placed in an inclined position in regard to the
bobbin, spool or tube such shield or guard preventing the tube before referred to
from falling too low and from receiving a swinging motion by the unwinding of the
sliver, slubbing or roving.
To enable the sliver, slubbing or roving to be readily inserted in the tube before
mentioned I form in the said tube a slit or slot formed preferably as a spiral or I
may cause the sliver, slubbing or roving to be passed through the said tube in any
other suitable manner.
The sliver, slubbing or roving while being unwound from the end of the bobbin,
tube or spool upon which the sliver, slubbing or roving has been wound will for
every time it revolves around such bobbin, tube or spool receive one turn of "twist,"
my invention thus enabling me to employ a sliver, slubbing or roving formed with
a less amount of twist than has hitherto been usually necessary, the additional twist
imparted by means of my invention imparting such strength to the sliver, slubbing
or roving as is requisite to support such sliver, slubbing or roving in its passage
from the bobbin, tube or spool upon which it had been previously wound to the
drawing or other rollers of the machine by which it is to be subsequently treated.
By being enabled to form slivers, slubbings or rovings with a less amount of twist I
am enabled by increasing the speed of the drawing rollers of the machines above
referred to, to increase the quantity of slivers or "slubbings" or rovings'
produced by a machine without increasing the speed of the spindles of such
machinery or by maintaining the rollers at their usual speed, to decrease the speed

Improvements in or connected with Machinery or Apparatus for
Preparing for Spinning and Spinning Cotton and other Fibrous
Materials.
I, WILLIAM HENRY RHODES, of 5 Lime Grove, Longsight in the County of
Lancaster, Machinist, 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 or apparatus for preparing for spinning and
spinning cotton and other fibrous substances, and consists in arrangements by which
I am enabled to impart additional twist to the sliver, slubbing or roving while
unwinding it from the bobbin, spool or tube upon which it has been wound and thus
to employ a sliver, slubbing or roving formed with a less amount of twist than is
usually necessary.
In performing my invention I mount the slubbing or roving bobbin, spool or
tube from which the sliver, slubbing or roving is to be unwound upon a fixed peg
projecting from a rail or board. I draw off the sliver, slubbing or roving from one
end of the bobbin, spool or tube upon which it has been wound and upon the said
sliver, slubbing or roving I place a tube through which the sliver, slubbing or
roving passes while being unwound from the bobbin, tube or spool. Upon the
upper end of the tube before mntioned I form or secure an enlarged part or collar.
While the sliver, slubbing or roving is being unwound from the bobbin, spool or
tube, the tube before mentioned will travel around the bobbin, spool or tube
preventing the portion of sliver, slubbing or roving being unwound from passing
into contact with the other portion of the sliver, slubbing or roving upon the bobbin,
tube or spool.
The lower end of the tube before referred to also tends to separate the portion of
the liver, slubbing or roving being unwound from the other portion of the sliver,
slubbing or roving.
I surround the bobbin, spool or tube from which the sliver, slubbing or roving is
being unwound, by a shield or guard placed like the bobbin, spool or tube in an
inclined position such shield or guard preventing the tube before referred to from
falling too low and from receiving a swinging motion by the unwinding of the sliver,
slubbing or roving.
I may cause the sliver, slubbing or roving to be passed through the said tube by
means of a hook or in any other suitable manner.
The sliver, slubbing or roving while being unwound from the end of the bobbin,
tube or spool upon which the sliver, slubbing or roving has been wound will for
every time it revolves around such bobbin, tube or spool receive one turn of
"twist," my invention thus enabling me to employ a sliver, slubbing or roving
formed with a less amount of twist than has hitherto been usually necessary the
additional twist imparted by means of my invention imparting such strength to the
sliver, slubbing or roving as is requisite to support such sliver, slubbing or roving
in its passage from the bobbin, tube or spool upon which it had been previously
wound to the drawing or other rollers of the machine by which it is to be subse-
quently treated.
By being enabled to form slivers, slubbings or rovings with a less amount of
twist I am enabled by increasing the speed of the drawing rollers of the machines
above referred to, to increase the quantity of slivers, or "slubbings" or "rovings
22

page_text: produced by a machine without increasing the speed of the spindles of such
machinery or by maintaining the rollers at their usual speed to decrease the speed
of the spindles without lessening the amount of slivers, slubbings or rovings
produced by the machines.
In order that my invention may be more readily understood I will now further
describe it with reference to the accompanying drawing in which the same letters
of reference are applied to corresponding parts in all the figures and the scales
to which the various figures are drawn are indicated.
Fig. 1 is a side elevation partly in section showing the arrangements in which my
invention consists and
Fig. 2 is a plan of that which is shown in Fig. 1.
Fig. 3 is a side elevation illustrating the manner in which the arrangements
illustrated in Figs. 1 and 2 are applied in a machine for preparing for spinning or
spinning cotton or other fibrous substances.
Fig. 4 is a longitudinal section and
Fig. 5 a plan illustrating the tube which I place upon the sliver, slubbing or
roving to be unwound from a bobbin, tube or spool and
Fig. 6 illustrates a hook which may be employed in passing the sliver, slubbing
or roving through the said tube.
In Figs. 1 and 2, a is a bobbin, spool or tube from which the sliver, slubbing or
roving is to be unwound. The bobbin, spool or tube a is as has been described
above, mounted upon a fixed peg 6 which may be made of any suitable material
but preferably of wood. The peg is secured by means of a screw b¹ in a
bracket c.
I draw off the sliver, slubbing or roving from one end of the bobbin,
tube or spool a as is indicated by the dotted line A and upon the said sliver,
slubbing or roving I place a tube d through which the sliver, slubbing or roving
passes while being unwound from the bobbin, tube or spool a. Upon the upper
end or part of the tube d which is shown upon a larger scale in Figs. 4 and 5,
I form or secure an enlarged part or collar d.
While the sliver, slubbing or roving is being unwound from the bobbin, spool or
tube a the tube d will travel around the bobbin, spool or tube a and prevent the
portion of sliver, slubbing or roving which is being unwound from passing into
contact with the other portion of the sliver, slubbing or roving upon the bobbin,
tube or spool a.
The lower end of the tube d also tends to separate the portion of
sliver, slubbing or roving which is being unwound from the other portions of such
sliver, slubbing or roving which remain wound upon the bobbin, spool or tube a.
The enlarged part or collar d' upon the tube d is chiefly of service in preventing
the portion of sliver, slubbing or roving which is being unwound from the bobbin,
spool or tube a from coming into contact with the angle or part a¹ of the sliver,
slubbing or roving upon the bobbin, spool or tube a when the sliver, slubbing or
roving is being unwound from the lower part of the bobbin, tube or spool a. I
surround the bobbin, spool or tube a from which the sliver, slubbing or roving is
being unwound with a shield or guard e of which the part e¹ is formed in one with
the bracket c and the part e' is formed of a piece of sheet metal secured to the
part el in any suitable manner as for instance by means of screws or rivets. The
part e of the shield or guard e being provided with a flange e³ and being also
formed with a conical recess e¹ which as is indicated in Fig. I receives the lower
conical portion a² of the sliver, slubbing or roving wound upon the bobbin, spool or
tube a serves to prevent the tube d from falling too low and thus becoming caught
beneath the said conical part a² or the base a³ of the bobbin, spool or tube a. The
part 2 of the shield or guard e as will be hereinafter more fully explained prevents
the tube from receiving a swinging motion by the unwinding of the sliver,
slubbing or roving and from passing too rapidly around the bobbin, spool or tube a.
When the arrangements illustrated by Figs. 1 and 2 are being applied to a machine
for preparing for spinning or spinning cotton or other fibrous substances the
bracket c is secured to another bracket which like the bracket c is as is indicated
in Fig. 3 made of a form and size adapted to the position in which the bobbin, tube

page_text: or spool a to be supported thereby is required to be placed. The pegs b upon which
the bobbins, spools or tubes a are to be mounted and the shields or guards e are for a
purpose to be hereinafter explained placed in an inclined position as indicated in
Fig. 3. The brackets are secured to a board or base g by which are supported
standards of which. one only is shown, supporting a bar or rail i provided with
hooks or guides over or through which the slivers, slubbings or rovings unwound
from the bobbins, tubes or spools a pass on their way to the rollers k of the
machine. The parts of the shields or guards e are as is indicated in Fig. 3
placed in such position that they are at the lower sides of the bobbins, spools or
tubes a upon the pegs b.
When a tube d like that illustrated in Figs. 4 and 5 has been placed upon the
sliver, slubbing or roving to be unwound from the bobbin, tube or spool a placed
upon each of the pegs the said slivers, slubbings or rovings, are conducted over
or through the guides or hooks j and passed between the rollers of the machine
for preparing for spinning or spinning cotten or other fibrous materials. Each
sliver, slubbing or roving while being unwound from the end of the bobbin, spool
or tube a upon which it has been wound will for every time it revolves around
such bobbin, spool or tube a receive one turn of "twist." The pegs upon
which the bobbins a are mounted and the shields or guards e are placed in an
inclined position in order that the motion of the tube d upon the sliver slubbing
or roving being unwound from each bobbin, spool or tube a may be confined
within suitable limits as would be impossible were the axes of the bobbins,
spools or tubes a placed in a vertical position and in order that at each passage
of the tubes d around the lower sides of the bobbins, spools or tubes a in con-
junction with which they are respectively employed the movement of such tubes d
may be checked or temporarily arrested or retarded by such tubes d arriving in
contact with the parts of the shields or guards e in order that the said tubes d
may be prevented from receiving a swinging motion by the unwinding of the
slivers, slubbings or rovings and from moving too rapidly around the bobbins,
spools or tubes a and so causing the slivers, slubbings or rovings to be unwound
therefrom more rapidly than such slivers, slubbings or rovings are caused to pass
between the rollers k.
The tubes may be made of metal and may be of any suitable size, but must
be made so light that the slivers, slubbings or rovings upon which they are to be
placed may support them without being injured strained or broken by the weight
of such tubes and for this reason I prefer that the collar d' upon each of the said
tubes d shall be made of wood.
The radius to which the part 2 of the shield or guard e is bent or formed
must be such that at no time can the tube d become fixed between such part e²
of the shield or guard e and the circumference of the sliver, slubbing or roving
wound upon the bobbin, spool or tube a.
وو
In passing the slivers, slubbings or rovings through the tubes d 1 may employ a
hook such as is illustrated in Fig. 6 which hook is formed of wire and is preferably
secured by a cord or otherwise to the person of the "ereeler
"bobbiner
whose duty it is to replace empty bobbins, spools or tubes by full bobbins, spools
or tubes.
or
Besides the advantages above mentioned my invention has the further advantages
that all the rovings are of approximately equal length from the places where they
leave the bobbins, spools or tubes upon which they are wound to the places where
they pass between the rollers of the machine for preparing for spinning or spinning
cotton and other fibrous substances and thus all the slivers, slubbings or rovings
being subjected to an equal and uniform tension the yarns produced will be
more uniform than those produced with the arrangements hitherto in use and
that the bobbins spools or tubes being stationary the "skewers" and "pots" or
other arrangements hitherto necessary to facilitate the revolution of the bobbins,
spools or tubes on which the slivers, slubbings or rovings are wound are entirely
dispensed with.

page_text: 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:-
1. For use in machinery or apparatus for preparing for spinning and spinning
cotton and other fibrous materials the hereinbefore described arrangements by
means of which a sliver, slubbing or roving being employed may have additional
twist imparted to it while being unwound from the bobbin, spool or tube upon
which it has been wound which arrangements consist in a tube such as d and a
shield or guard such as e arranged and employed substantially as hereinbefore
described in reference to and indicated in and by Figs. 1, 2, 3, 4 and 5 of the
accompanying drawing and for the purpose of enabling the sliver, slubbing or
roving to be drawn off or unwound from one end of the bobbin, spool or tube upon
which it has been wound.
-
2. For use in machinery or apparatus for preparing for spinning and spinning
cotton and other fibrous materials a tube such as d constructed and employed for
the purpose and substantially as hereinbefore described in reference to and indicated
in and by Figs. 1, 2, 3, 4 and 5 of the accompanying drawing placed upon each
sliver, slubbing or roving to be unwound from a bobbin, spool or tube and enabling
such sliver, slubbing or roving to be unwound or drawn off from one end of the
said bobbin, spool or tube.
3. For use in machinery or apparatus for preparing for spinning and spinning
cotton and other fibrous materials a shield or guard such as e formed, arranged and
employed substantially as hereinbefore described in reference to and indicated in
and by Figs. 1, 2 and 3 of the accompanying drawing and for the purpose of
preventing the tube placed upon each sliver, slubbing or roving from falling too
low and from receiving a swinging motion from the unwinding of such sliver,
slubbing or roving.
4. For use in machinery or apparatus for preparing for spinning and spinning
cotton and other fibrous materials the arrangements herein before described and
ilustrated by Fig. 3 of the accompanying drawing which enable each of the
slivers, slubbings or rovings being employed to be drawn off or unwound from the
end of the bobbin, spool or tube upon which such sliver, slubbing or roving has
been wound and so render it possible to impart additional twist to the slivers,
slubbings or rovings being employed while they are being unwound from the
bobbins, spools or tubes upon which they have been wound.
