I JOHN ALEXANDER SPARLING of 178 Lancaster Road Notting Hill in the
County of Middlesex Gentleman do hereby declare the nature of my said Invention
for "A NEW MANUFACTURE OF COVERED COTTON OR OTHER CORES AND THE
MACHINERY OR APPARATUS TO BE EMPLOYED THEREIN to be as follows:-
"
My new manufacture consists in the use of a hollow spindle upon which two or
more spools or bobbins of the covering material are placed-the threads from such
spools or bobbins being brought through a moveable top attached to such spindle
which is perforated with holes for that purpose and which is fixed or screwed to
the spindle so as in fact to form part of, and to revolve with it in an outer bearing
large enough for it to work in and which spindle also carries a frame to hold guide
eyes for the threads.
The object of this arrangement is two-fold, first to produce an even covering
with less silk or other covering material than in the usual method by reason of
the threads being separately delivered instead of being all delivered together and
pressed flat as delivered;-and secondly by steadying the end of the spindle to
drive at a greater speed-The spindle carries a screw or worm working into a cog
wheel fixed on an ordinary spindle carrying another screw or worm which works
another cog wheel which is attached to the receiving drum or disc-so that the
speed of the spindle regulates also the speed of the receiving drum or disc.

I, JOHN ALEXANDER SPARLING, late of 178 Lancaster Road, Notting Hill, now
of 32 Norfolk Terrace, Bayswater in the County of Middlesex, Gentleman, 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 has reference to a new manufacture of covered cotton or other
cores and the machinery or apparatus to be employed therein.
I use a hollow spindle upon which two or more spools or bobbins of the covering
material are placed, the threads from such spools or bobbins being brought through
a rotary disc that I call a "top" attached to such spindle and which is perforated
with holes for that purpose and is fixed or screwed to the spindle so as in fact
to form part of and to revolve with it in an outer bearing large enough for it to
work in, and which spindle also carries a frame to hold guide eyes for the threads.
The object of this arrangement is two-fold, first to produce an even covering
with less silk or other covering material than in the usual method, by reason of
the threads being separately delivered instead of being all delivered together and
pressed flat as delivered and secondly by steadying the end of the spindle to
enable it to be driven at a greater speed. The spindle is geared to a wheel fixed
on an ordinary spindle carrying a screw or worm that works a wheel which is
attached to the receiving drum or disc-so that the speed of the spindle regulates
also the speed of the receiving dram or disc.
Referring to the accompanying sheet of illustrative drawings Fig. 1 is a side
view, Fig, 2 a plan, and Fig. 3 an end view of machinery or apparatus according to
my invention. Figs. 4 and 5 are transverse sections on the lines A. B and C. D
respectively Fig. 2. Fig. 6 shews in elevation a modified form of spool or bobbin
carrier. 1 is a hollow spindle or driving shaft to which is or are fixed at or near
one end a driving pulley or pulleys 2, and at its other end a "top" 3. The top
is in the form of a disc with as many holes through it as there are covering threads
to be wound, these holes being inclined to the axis of the spindle as indicated
in Fig. 1. The top rotates in a bearing in the standard or frame 4; the spindle
near its other end rotates in a standard or frame 5, endwise movement of the
spindle being prevented. The spindle 1 being mounted as described may be driven
at high velocity, without liability to injurious vibration. 6. 6 are spools or bobbins
of silk or other covering material; they are mounted upon pins 7, 7 fixed to discs
or carriers 8. 8 secured to the hollow spindle ]. 9, 9 are fallers of elastic material,
such as steel wire, pivotted to projections 10, 10 on the carriers 8. and equal in
number to the spools or bobbins 6. One end of each faller is arranged to bear
against its carrier 8 when in its normal working position, its outer end being bent

page_text: or formed into an eye through which the thread from one of the spools or
bobbins 6, is passed. 11, 11 are guide eyes or hooks formed of wire, secured to the
carrier 8 that is nearest the top 3; they serve to guide the threads passing from
the spools.or bobbins on the other disc or carrier 8 to the top 3. 12 is the grooved
receiving drum or disc round which the covered cotton, wire or other core is
automatically wound during the covering operation. It is secured upon a shaft 13
carried in uprights 14 of the machine frame and receives notion from the hollow
spindle 1 as follows. 15 is a pinion secured to the spindle 1 and gearing with a
toothed wheel 16 secured to a shaft 17 capable of rotating in bearings 18 in or on
the standards 4, 5 and 19. 20 is a worm fixed on the shaft 17 and gearing with a
wheel 21 fixed to the shaft 13 that carries the drun or disc 12 and thus com-
municating motion to the latter when the spindle 1 rotates. 22 is a guide pulley
pivotted to an upright 23; it serves to guide the covered cotton or other core to
the drum or disc 12.
For the purpose of automatically stopping the machine when all the thread has
been drawn from any of the spools or bobbins or in the event of breakage of a
thread I provide a thread or wire 24 one of its ends being secured to a pin 25
whilst its other end is led between a pair of rollers 26 and connected to a lever 27
pivotted at 27* to the standard 5. One end of this lever is so formed that if the
thread or wire 24 stretched between the standards 4, 5, be pulled or pushed
upward or downward, as will hereinafter appear, it will be raised and by contact
with a pin 28 fixed to the back of one of the pulleys 2 will arrest the rotation of
the spindle 1 and thus stop the machine. To enable the lever to be readily raised,
its arin, to which the thread or wire is attached, is nearly counterbalanced either
by prolonging the arm beyond its pivot as shown, or by a spring or springs. 29 is
a pin or stop to prevent the lever arm rising too high. 30 is the core to be
covered; it passes through the hollow spindle 1 as shown.
The operation of the machine or apparatus is as follows:-The ends of the
threads or fibres of silk or other covering material on the spools or bobbins 6 are
each first passed through the eye of its respective filler (and guide eye 11 where
necessary) and then led away and passed separately through a perforation in the
top 3, as clearly indicated in Figs. 1 and 2. The core or wire to be covered is
passed through the hollow spindle 1 and its forward end together with the ends of
the threads or covering to be wound upon it (which ends are suitably arranged
around the said core or wire), are secured to the drum or disc 12 in any convenient
manner. Rotary motion is then imparted to the spindle 1 thereby causing the
covering threads to be simultaneously but separately wound round the core. By
using several spools or bobbins and operating them as above described the
description of silk known as singles may be employed in lieu of the doubled silk
ordinarily used and thus the expense and wa-te that obtain in the process of
doubling may be avoided. Whilst the machine is efficiently working the fallers 9
are drawn by the tension of the threads into about the position indicated in the
drawings but should one of the covering threads become broken or exhausted, the
faller through which it was guided being then relieved of tension will be thrown
out by centrifugal force assuming the attitude indicated by a dotted line in Fig. 2.
so as by contact with the thread or wire 24 to arrest the spindle 1 by means of the
lever 27.
In the modified form of spool or hobbin carrier shown in Fig. 6 three discs 32,
33, and 34 are employed whereof 34 is fixed to the spindle 1. The discs are forced
towards each other by a spring 35 situate between 32 and a fixed collar or stop on
the spindle 1, and are each provided with pins or projections 36 whereon the spools
or bobbins 6 are loosely mounted. The spools or bobbins can be easily removed or
replaced as the disc 32 can be readily moved lengthwise on the spindle 1 towards
the collar or stop, or the discs 32 and 33 from the disc 34, against the action of the
spring 35. The centre dise 33 is provided with a sleeve or long bearing 37 to
maintain it at right angles to the spindle 1 and prevent its shaking.

page_text: 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 I do
not lay any general claim to the covering of cotton or other cores with silk or other
threads, but what I claim is
1. The manufacture of covered cotton or other cores in the peculiar manner
bereinabove described.
2. Machinery or apparatus substantially as described and shewn for the manu-
facture of covered cotton or other cores the arrangement being such that the
threads are separately delivered and wound upon the core as set forth.
3. The arrangement substantially as described for steadying the end of the
spindle that carries the top or perforated disc, and regulating the speed of the
receiving drum by means of that spindle.
