AN IMPROVED MACHINE FOR WINDING SPOOLS OR BOBBINS FOR NET MAKING MACHINES
Year: 1884

page_text: THOMAS HELYEAR, West Street, Bridport, Dorset, Engineer and Machinist do
hereby declare the nature of my invention for AN IMPROVED MACHINE FOR WINDING
SPOOLS OR BOBBINS FOR NET MAKING MACHINES, to be as follows:-
The spools or bobbins are driven by friction, by such means you can stop one
bobbin or all of them, or work them one or all at any time while the machine is
running, they can be stopped as long as you think proper or they can be put to
work in an instant by my lever motion. The traverse is self acting or by cams,
levers, or eccentrics you can shift it from one end to the other while the machine is
running. And plates on the bottom of spools or bobbins to prevent them slipping
off while the machine is in motion.
My machine is made of iron, and the spindles for bobbins to go on are horizontal,
driven by bevel friction. A lever attached to each spindle, by lifting this lever on
a rest the spindle will be stationary as long as this lover is on the rest, and by lifting
it off the rest the spindle is in motion immediately. If the work should break, they
do not want to stop the machine but they stop one or more bobbins or spools
according to the work that has broken down, and all the other parts can still be
working. The plates for holding the spools or bobbins on the spindles are let in
to the bottom of the spool or bobbin. The spindle that it goes on has a pin through
it and this spool or bobbin with plate on is put on this spindle, there is a slot in the
plate that fits on the pin through the spindle, it can go no further on or off till it is
taken off, and to take it off is no trouble. The traverse is self-acting from one end
to the other of the spool or bobbin, backwards and forwards, or I have a motion
which can be attached, when the traverse has run out to the end of the bobbins or
spools, with cams, eccentrics and levers, I can shift the traverse, in one minute from
one end to the other of the bobbin or spool without stopping the machine, so my
machine can be kept running from 6 o'clock in the morning to six 6 o'clock at night
and not want to stop to take off or put on work. For winding cotton I use reels
fixed, on above the bobbins or spools, they never want to be taken off to put the

page_text: work on, it is put on while they are in their places and the machine running, by
that means the machine will do a great deal more work with less hands.
The traverse is worked with two hearts or cams and two screws the length the
traverse is required to work. That depends on the length of the spools. The
traverse can be worked backwards and forwards continually till the spool or bobbin
is full, or you can start the traverse at one end of bobbin or spool and work it till
it gets to the other end, and if you wish to be continually working one end I have
4 half-nuts attached to levers, cams, and eccentrics, that can stand in the middle of
the machine and open those nuts at both ends and shift the traverse back to the
other end in one instant without stopping the machine, and you can be continually
working from one end if required.

page_text: I, THOMAS HELYEAR of West Street, Bridport, Dorset, Engineer and Machinist,
do hereby declare the nature of my invention for "AN IMPROVED MACHINE FOR
WINDING SPOOLS OR BOBBINS FOR NET MAKING MACHINES," and in what manner
the same is to be performed to be particularly described and ascertained in and by
the following statement:―
The object of my invention is the provision of a machine for driving spools or
bobbins by friction in such manner that one or all or any number of a set of
bobbins may be worked or stopped whilst the machine is in motion. The traverse
is self neting and may be shifted from one end of its travel to the other end also
whilst the machine is in motion. At the bottom of the spools or bobbins are plates
by which they are secured to their spindles.
Referring to the accompanying three sheets of illustrative drawings:—
Fig. 1. is an end elevation of a machine constructed in accordance with my
invention.
Figs. 2 and 3 are respectively a front elevation and plan of the same, and
Figs. 4 and 5 are respectively an end view and a longitudinal section of one of
the bobbins on a large scale, clearly shewing the details of its construction.
In the whole of the figures similar parts are indicated by the same figures or
numbers of reference.
1 are vertical standards connected together by the longitudinal girders 2, on
which are carried bearings 3, for the bobbin spindles 4, at one end of each of which
is mounted a bubbin 5, the other end of each of the bobbin spindles 4 carrying a
bevel friction wheel 6 so that it may freely slide thereon guided by a feather, a
certain distance in a longitudinal direction, but always revolving with the bobbin
spindle. 7 are bevel friction wheels fixed on the main driving shaft 8 for actuating
the bevel friction wheels G and consequently the spindles 4 and bobbins 5. The
wheels 6 are put in and out of gear with the wheel 7 by lowering and raising the
end 9 of the bell crank lever 10, mounted on a bracket 10° supported by a bar 10b
running lengthwise of the machine, which bell crank lever 10 operates the bifurcated
clutch lever 11 through the link 12, the lever 11 being pivotted to a bracket 13 fixed
to the girder 2. The end of the bell crank lever is weighted with the weight 14 so
as to keep the bevel wheels 6 and 9 normally in gear with each other and when
these are put out of gear, the end 9 of lever 10 rests on the supporting bracket 15
fixed to the longitudinal bar 16.
The bobbins are prevented from turning round on, or slipping off their spindles
by means of the arrangement shewn in Figs 4 and 5. The pin 17 is fixed in the
spindle 4 and is then passed into the bobbin through an end plate 18 with an
aperture to allow of such passage. At the back of the end plate and either fixed to
or formed in one piece with the same are two hollow stop brackets 19 the raised
sides 20 of which prevent the spindle from turning beyond a short distance without
carrying the bobbin with it. When the spindle is at the end of such short distance,
the pin 17 will then have travelled past or across the aperture in the end plate 18
and will thus be prevented from slipping out of the bobbin 5 endwise. The end
plate 18 is secured to the bobbin 5 by screws 21.
Motion is communicated to the machine from the main driving shaft 8, through
the toothed wheels 22, 23, 24, 25; to the shaft 26 on which are fixed cams 27.

page_text: The traversing apparatus for distributing or guiding the thread or twine along
the bobbins is in duplicate, that is to say, it is similar at each end of the machine,
consequently it will be sufficient to describe one of the said apparatus, which is as
follows:--
.
The cam 27 communicates through the roller 28 an oscillating motion to the three
armed lever 29, 30, 31, on the centre stud 32 on the bracket 33 which is securely
fixed to the main frame 1. On the arın 31 is a counter weight 34 for the purpose

arm 30 is a stud pin 35 to which is jointed the connecting rod 36 the other end of
such connecting rod being connected to the crosshead 37 by cross pin 38. The cross-
head 37 is keyel or otherwise securely fixed to the spindle 39 which is attached to
the head 40 of the traversing carriage constructed of the two heads 40, 41
firmly secured together by means of the distance bars 42, 43. In the centre of
the traversing carriage is fitted a screw 44 passing through the whole length of the
carriage and secured longitudinally by collars 45 and nut 46. Ono end of the
screw is provided with a toothed wheel 47 and pawl 48 with pawl lever 49 this
latter working in the inclined guide frame 50. The whole of the traversing carriage
slides along the bars 51 which pass through the heads 40, 41 and are secured at their
ends to the angle brackets 52, 53 fixed to a sole plate 54 attached to the main frame
by bolts and the jib stay 55. The ends 29, 30 of the lever 29, 30, 31 are provided
with slots to admit of the adjustment of the stud pins and consequently allow the
travel of the traversing carriage to be varied within certain limits depending on the
length of the slots.
Mounted upon the three standards and sole plates are three supporting guides 56
for carrying the long traversing beain 57 which extends the whole length of the
machine as shewn and having a number of thread guides 58 fixed vert cally over
the centre of the different bobbin spindles. At each end of the traversing beam in
position vertically over the screw 44 in the traversing carriage is a bracket 59
carrying the tongs shaped levers 60 jointed at 61 the ends of which are formed
with internal screw threads corresponding to the thread of the screw 44 in the
traversing carriage. The jaws 62 may be caused to embrace the screw of the
traversing carriage by means of mechanism to be presently described. On the
upper part of the bracket 59 is fitted a disc plate 63 free to rotate round the
stud 6 and provided with slots 65 through which the ends of the tongs shaped
levers are inserted, the slots being formed after the manner of spirals or involutes it
will be seen that any rotary movement of the disc plate will cause a corresponding
opening or closing of the levers 60 and will consequently cause the screw threaded

is a crank pin 66 connected to the long connecting plate 67 which is guided on the
beam 57 by means of screws 68 working in the slots 69. The connecting plate 67
is moved in either direction by the lever 70 thus turning the disc plate through the
desired angle.
On the standards 71 are mounted reels for receiving the banks of thread or twine
to be wound upon the bobbins.
I will now proceed to describe the mode of operating the machine.
The bobbins having been placed upon their spindles and the hanks of thread o
twine to be wound placed upon the reels the free ends of the thread or twine ar
passed through the guides 58 and attached to their respective bobbins. The weighted
onds 9 of the bell clank levers 10 are then released from the supporting brackets 15

turned, causing (through the plate 67 and crank pin 66) the disc plates 63 to turn
in such manner as to open the threaded jaws 62 free of the screws 44. The
traversing beam 57 is then pushed forward into the required initial position fo
commencing the winding operation on the bobbins, that is, into such a position tha
the guides stund vertically over the conical portion of the bobbins; the jaws 62 ar
then caused to embrace the screws 44 of the traversing carriages by turning the
lever 70. The machine is then set in motion, the traversing mechanism causing the

page_text: traversing beam 57 to guide the thread or twine over the conical portion of the
bobbins and back again. During the double stroke of the traverse, the levers 49
of the pawl mechanism have been caused to travel up and down the slot in the
inclined frame 50 thereby causing (through the action of the pawl and toothed
wheel 48, 47 the screw to turn through an angle sufficient to advance the traversing
beam through a distance equal to double the thickness of the thread or twine to be
wound, thus at every double stroke of the traversing apparatus the initial position
of the traversing beam is advanced so that the bobbins are wound by a series of
conical or capping windings each winding being a step in advance of the other until
the bobbins are filled.
By reversing the bobbins on their spindles and the pawls 48 I am enabled to
wind from the opposite extremity of the traverse.
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,
