Improvements in the Method of and Apparatus for Removing the
Residue or Excess of Roving or the like from Bobbins or Tubes
used in Spinning.
We, ALFRED TAYLOR, of Lower Townhouse, Littleborough, in the County of
Lancaster, Manager, and OSCAR SCHOFIELD, of Oakenrod House, Rochdale, in the
aforesaid county, Cotton Spinner and Manufacturer, do hereby declare the
nature of this invention to be as follows:-
Our said invention relates to improvements in the method of and apparatus
for removing the residue or excess roving, or the like, left on the bobbins or
tubes used in spinning, as is well understood.
After the building of one or more set of cops upon the spindles, say for
example in a spinning mule, there is usually a slight residue of roving left on
the supply bobbins. Under one method of removing such roving the bobbins
are taken from the creel and the roving cut from the bobbins by means of a
knife. This practice is not only slow and laborious, but the bobbins rapidly
become scored or grooved by the cuts from the knife whereby their durability is
affected. In addition, the scores or cuts in the bobbin are apt to harbour oil
which is ultimately taken up by the roving so that the quality of the spun yarn
is impaired.
Under another method the tubes or bobbins are slightly tapered so that the
residue or excess roving may be stripped off, but this is in itself an evil as many
of the full rovings are apt to slip too, owing to the tapering formation of the
tubes.
According to our invention we propose to remove such excess roving from the
bobbins or tubes by mechanical means, and without any cutting of the roving
whatever, at the same time using a tube of an equal diameter throughout.
In a suitable arrangement for carrying our invention into effect we provide
a shaft mounted in bearings carried in a suitable frame or support. This shaft
is furnished with fast and loose pullies for driving purposes.
Strung upon the said shaft are a number of drums or pullies, against the
peripheries of which, bear a similar number of rollers sustained in suitable
bearings supported from the frame of the machine. When the drums or pullies.
strung upon the shaft revolve, they frictionally operate the said rollers. The
bobbins are placed on loose spindles, skewers, or creel pegs, suitably supported
in front of the said drums or pullies, the bobbins being caused to revolve by
reason of their contact with the said drums or pullies.
When the machine is in operation the attendant slips the bobbins containing
the roving upon the loose spindles, skewers, or creel pegs, and throws the end
of the roving to the bite of the revolving drum and roller, which parts rapidly
draw off the roving from the bobbin and lower the same into a suitable receptacle.
The roving preferably passes over a guide arranged between the spindle and the
bite of the drum and roller or this guide might be made to support the bobbins.
We may arrange for more than one bobbin to bear against each drum or pulley
if thought desirable.

page_text: By means of our invention the length of roving is removed from the bobbin
without cutting the fibre, the life of the bobbin is indefinitely prolonged, and
the absence of cuts on the bobbins prevents oil soaking through and staining the
roving so that the quality of the yarn produced is much improved.

Improvements in the Method of and Apparatus for Removing the
Residue or Excess of Roving or the like from Bobbins or Tubes
used in Spinning.
We, ALFRED TAYLOR, of Lower Townhouse, Littleborough, in the County of
Lancaster, Manager, and OSCAR SCHOFIELD, of Oakenrod House, Rochdale, in the
aforesaid County, Cotton Spinner and Manufacturer, 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_and_
accompanying drawings:-
--
Our said invention relates to improvements in the method of and apparatus
for removing the residue or excess roving, or the like, left on the bobbins or
tubes used in spinning,-as is-well-understood.
After the building of one or more set of cops upon the spindles, say by way of
example in a spinning mule, there is usually a slight residue of roving left on
the supply bobbins. Under one method of removing such roving the bobbins
are taken from the creel and the roving cut from the bobbins by means of a
knife. This practice is not only slow and laborious, but the bobbins rapidly
become scored or grooved by the cuts from the knife whereby their durability is
affected. In addition, the scores or cuts in the bobbin are apt to harbour oil
which is ultimately taken up by the roving so that the quality of the spun yarn
is impaired.
Under another method the tubes or bobbins are made slightly tapered so that the
residue or excess roving may be stripped off, but this is in itself an evil as many
of the full rovings are apt to slip too, owing to the tapering formation of the
tubes.
According to our invention we propose to remove such excess roving from the
bobbins or tubes by mechanical means, and without any cutting of the roving
whatever, at the same time using a tube of an equal diameter throughout.
Our invention will be clearly understood from the following description
reference being had therein to the annexed sheet of drawings, in which:-
Fig. 1 shows in front elevation an apparatus constructed in accordance with
our invention.
Fig. 2 is an end elevation of Fig. 1.
Fig. 3 is a sectional view of the drum and frictionally driven roller.
Figs. 4, 5 and 6 show plan views of bobbins, with the means for supporting
and preventing endwise movement of such bobbins when they bear against the
drums.
Fig. 7 is a detail sectional view and shows a means which may be employed
for shifting the driving belt.
In a suitable form of apparatus for carrying our invention into effect we provide
a shaft a mounted in bearings or brackets 6 secured to a bed plate c which may
be supported in any suitable manner as for instance by standards d. The said

page_text: shaft a is furnished with fast and loose pullies e e¹ for driving purposes the
driving belt being conveniently shifted by means of a pivotted fork f operating
by a sliding bar or rod y arranged across the front of the machine.
Strung upon the shaft a are a number of drums or pullies h, against the peri-
pheries of which bear a similar number of rollers i sustained in bearings formed
in the upper ends of the brackets 6 as clearly shown in Fig. 2.
To prevent trapping accidents the rollers are so mounted as to be free to rise
in their bearings. When the drums or pullies h, strung upon the shaft a
revolve, they frictionally operate the said rollers i. The bobbins A which con-
tain the excess roving A¹ are placed on loose spindles, skewers, or creel pegs 1
the said skewers or the like being suitably supported in front of and against the
said drums or pullies h by means of arms or extensions & formed on or secured
to the rackets b. With the pegs bearing on the arms the top and bottom of
the bobbins prevent endwise movement, the bobbins being caused to revolve by
reason of their contact with the said drums or pullies h.
When the machine is in operation the attendant slips the bobbins containing
the roving upon the loose spindles, skewers, or creel pegs 7, and throws the end
of the roving A to the bite of the revolving drum and roller i, which parts
rapidly draw off the roving from the bobbin the roving falling from the back
of the machine or being lowered into a suitable receptacle. The roving may
pass over a guide m arranged between the bobbin and the bite of the drum and
roller or this guide might be made to support the bobbins as is indicated in plan
view Fig. 5.
In this case endwise movement of the bobbins is prevented by abutment
pieces m secured to the guide m.
We may arrange for more than one bobbin to bear against each drum or pulley,
if thought desirable.
Instead of mounting the bobbins on skewers, the bobbins may be dropped into
and revolve in pockets n formed by securing a plate or strip to the arms b' as
is indicated in the plan view Fig. 6 and the right-hand half of Fig. 1.
An apparatus such as we have described is extremely simple, and can be
worked by a half-timer who can empty twice as many bobbins in a given time as
can be emptied by hand. In addition to this, the length of roving is removed
from the bobbin without cutting the fibre, the life of the bobbin is indefinitely
prolonged, and the absence of cuts on the bobbins prevents oil soaking through
and staining the roving so that the quality of the yarn produced is much
improved.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is:-
1) As a means for mechanically removing the residue or excess roving or the
like from bobbins or tubes used in spinning machines an apparatus consisting of
a drum caused to revolve in a convenient fashion and to drive rollers in contact
therewith the bobbins being supported against the drum and the roving removed
in the manner and substantially as described.
2) The improved apparatus for removing the residue or excess roving from
bobbins and tubes used in spinning machinery constructed arranged and acting
in the manner and substantially as hereinbefore described and shown.
