Improvements in Bobbins and Carriages used in Lace-making
Machines.
ARTHUR PARSONS of Eldon Chambers Nottingham Gentleman and EDWIN
WHITWORTH of the same Town Consulting Engineer do hereby declare the nature of
this invention to be as follows:
The object of this invention is to improve the construction of Bobbins & carriages
& the like us in Lace Machinery and make them in such a manner that they can
be used in a more economical manner than at present.
In the construction of Bobbins & carriages as at present used a flat thin Bobbin
made of brass or any other suitable material is so constructed as to be capable of being
inserted into a receptacle called a carriage.
This carriage is also of metal & is made in such a way that in the large opening
forming the bearing for the Bobbin a small projecting rib of metal is left extending
over a part of its internal opening & this rib enters, between the two flanges or sides
constituting the sides of the Bobbin & holds it in position for rotation within the
carriage.
A spring is also attached to the upper part of the carriage which when in position
presses downwards upon the Bobbin & keeps it on its seat on the projecting rib of
the carriage, an eve is provided at the upper part of the carriage to receive the end
of the thread which is wound on the Bobbin & from whence it is drawn when in use
in the Machine in the act of Lace Making, and the ordinary course in using
Bobbins & Carriages is as follows.
Supposing the Bobbin to be in the Carriage it is taken out by hand & the Bobbin is
passed to the winder who fills it with silk or cotton thread, as may be required, on a
special machine in use in the trade for this purpose & in some cases the Bobbins are
wound singly & in others a number of Bobbins are wound simultaneously but in
either case the Bobbins being wound are replaced in the carriage by hand & the end
of the thread passed thro' the eye or "threaded" & the Bobbin & its carriage is then
replaced in the Machine to be used in making Lace until the time arrives when it is
again emptied & requires refilling & the same routine is gone through as before & as
it is obvious from the structure of the Bobbins that their capacity is small it will be
seen that the Bobbins require taking in & out repeatedly to be rewound.
And in our invention we inodify the construction of the Bobbins & carriages so as
to permit the Bobbins to be refilled without taking them from the carriagos & by so
doing we save in the labour & time & the number of Bobbins & carriages used in
this machinery being very large we obtain a considerable advantage. In constructing
Bobbins & carriages in our improved manner we do not depart from the main
features of ordinary Bobbins & carriages so that existing Bobbins & carriages can be
altered according to our invention, Supposing that an ordinary Bobbin & carriage
is required to be altered according to our improvements we only thin down or
remove a portion of the carriage so as to allow a small part of the periphery of the
Bobbin to be exposed & this part of the carriage is so modified that altho' it allows
the periphery of the Bobbin to be partly exposed yet it is effectually guarded from
injurious contact with any of the threads used in the machine & this modification of
the carriage can be arranged to take place either on the top or bottom or the side of
the carriage without interfering with the result. We also modify the construction*
of the Bobbin in the following manner, on one or both of the sides of the Bobbin
&preferably near the periphery we place a small projecting piece of metal attached to
& forming part of the flange, but so constructed as to have no effect upon the use of
the Bobbin normally but of such a form as that supposing the Bobbin to be in its

page_text: n
place in the carriage & ŉ thread applied to the part of the carriage thinned down or
inodified in form & the Bobbin rotated, the projecting portion of the Bobbin
constituting a self acting feed engages with the thread or end of the thread & it is
wound without any further trouble it may be used on any part of the Bobbin, at
bottom or at any intermediate position in the side. The feed part or small piece
engaging the thread or end of the thread can be made in several forms without
departing from the general effect as above described.
And also instead of being a piece added on to the Bobbin it may be a piece
taken away from it & forming a narrow slit preferably at the periphery & made in
such a position that the normal operations of the Bobbin & carriage shall not be
interfered with.
This method of constructing our improvement is particularly suited to single
winding & in any of its modifications the general feature of securing the thread &
starting the winding without any trouble or loss of material may be employed on
ordinary Bobbins taken from their earringes & wound in the ordinary way & is of
considerable advantage. Some of the Bobbins used in the Lace machinery after
filling are heated or steamed & put into a press in order to bring the Bobbins back to
the normal thickness, the operation of winding or filling tending to spread or open
out the Bobbins & in order to enable this to be done under our improvement we place
a series of plates or dises between the Bobbins & carriages so that one plate falls
between two adjacent Bobbins & we construct them in such a manner that on
pressure being applied to the top of a series or number of Bobbins & earringes so
arranged the thrust is borne by the Bobbins alone without interfering with the
carriages & they can be heated or steamed & pressed in the ordinary way.

Improvements in Bobbins and Carriages used in Lace-making
Machines.
ARTHUR PARSONS of Eldon Chambers Nottingham and EDWIN WHITWORTH of the
same Town Consulting Engineer 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 :—
The object of this Invention is to improve the construction of Bobbins and
Carriages used in Lace Machinery, and to make them in such a manner that they can
be used in a more economical manner than at present. In the drawings hereunto
annexed we shew various views of a Bobbin and Carringo.

page_text: DESCRIPTION OF DRAWINGS.
In figure 1 sheet | A is the carriage containing the bobbin B and we modify the
carriage by cutting a way or reducing it at A figures 1 and 2 so as to allow a
thread to be inserted into the bobbin whilst in the carriage.
The bobbin B contains a small feed piece D attached to the bobbin in such a
manner figures (L. 3. 4 and 5) as to have no effect upon the normal use of the bobbin
but so placed that when the thread is inserted into the bobbin B as shown in
figure 1 and the bobbin rotated as in winding the feed piece D engages with the
thread and commences to wind the thread which then goes on without any further
attention.
Figures 3.4 and 5 show the action of the feed in engaging and retaining the
thread and the position and manner of making the feed piece D it will be seen that
although the feed readily engages the thread when inserted in the bobbin as in
figures 1 and 3 yet when it again comes round as in figure 5 it has no action upon
the thread the feed piece being so constructed as to be guarded in this position
figures 6, 7 and 8 are views showing section of bobbin and feel piece D and the
formation of the bobbin allowing the thread to be seized by the feed piece D when the
thread is in the required position.
Instead of using a food piece inserted in the side of the bobbin as described above
we also use a modification shown in figure 9 where a slot E is cut inside of bobbin
and the thread being inserted in the carriage as in figure 1 and the bobbin B rotated
in act of winding the thread Centers into and is engaged by the slot E and
50 commences the winding, figure 10 shows another modification of our invention
where a driver F carried on the winding spindle G is provided with a slit Finto
which the end of the thread is inserted (after being put in bobbin) and the bobbin
rotated by the winding spindle G the driver F participates in the motion and the end
of thread C being engaged by the driver F the winding is effected.
Figure 11 is a side view shewing driver on same spindle G as the bobbin B.
In figures 12 and 13 we show another modification of our invention in which
the operation technically known as "Threading" (e. inserting the throad Cinto the
eye H in the carriage A) is performed at the same time as starting the winding this
is effected by modifying the construction of the eye H in the carriage in the manner
shewn in figures 12 and 13 sheet 2, a slit H¹ is made in an inclined direction in
carriage A so as to communicate with the eye HI the effect of this is that supposing a
thread Ċ to be inserted into a bobbin contained in a carriage modified according to
our invention as in figures 12 and 13 sheet 2, in order to wind or fill it the net of
placing the thread in the bobbin causes the thread (to first enter into the slit H¹
communicating with the eye H in carriage A and finally into the eye H and so
completes the operation of threading.
It will be observed that the formation of the inclined slit H in the carriage A is
such that a thread being inserted in the position shown cannot readily come out
again the formation of the eye and slit being similar in effect and the ordinary
weavers eye.
In carrying out our invention as shewn and described it will be noticed that the
act of winding the bobbins within the carriages causes more wear in both than is the
case with the ordinary method of winding where the bobbin is removed from
the carriage to be wound and afterwards replaced in the carriage and threaded and
although this is more than counter balanced by the saving in time and labour effected
by our invention we have modified the construction of the carriages so as to meet
this objection this modification is shewn in figures 15, 16 and 17 where the Bobbin
runs in small friction wheels III inserted in the carriage A in such a manner that
the bobbin runs upon them alone instead of the ordinary way (shewn in figures 1
and 2) thus converting the motion into a rolling one instead of a rubbing one.
The method of inserting these rolls or wheels is shown in figures 15 where two
rolls or wheels II' are inserted in the carriage A and one I" is carried by the spring J.

page_text: Figures 16 and 17 are enlarged views showing manner of inserting friction wheels
or rolls, we find that this mo lification runs very easily and with much less wear than
the ordinary construction and is more regular in the pull on thread or in the friction
between babbin and carriages and dispenses with lubricating as at present used. This
enables more delicate threads to be used without so much breakage &..
Having now deseriled and ascertained the nature of our invention and manner of
performing the same we would have it understood that we claim.
1. The construction of bobbins and carriages in meh a manner that they can le
wound without taking the bobbin from the enrriage.
2. The threading the carriage at same time as starting the winding.
3. The modification shown in figures 15. 16 and 17 using friction wheels for the
hobbins and run on.
