PROVISIONAL SPECIFICATION.
Improvements in Machines for Covering or Braiding Over Cord,
Rope, Wire, and the like.
I, PETER JENSEN of 77 Chancery Lane, London, Chartered Patent Agent do
hereby declare the nature of this invention (a communication to me from abroad
by Anton Kreidler of 56 Kasernenstrasse Stuttgart, Germany, Manufacturer) to
be as follows :—
The object of this invention is an improved bobbin or spool for covering or
braiding machines of all kinds, such bobbin consisting essentially of an inner or
core part forming the bobbin proper and a flanged sleeve thereon which carries the
covering material.
As is well known the bobbins which carry the covering material (for instance
silk, cotton or jute) in covering and braiding machines are of wood and sometimes
provided with a lateral slit for enabling the removal of same when run empty. If
the working of the machine is to be suitable the number of spare bobbins or spools
must be large and they must be kept ready filled with the covering material. Their
small size however necessitates their frequent removal. Considering that the
bobbins or spools cannot possibly be made exactly alike in all parts it is obvious
that the insertion of a fresh bobbin or spool often may cause interruptions such as
tedious adjustment of the tension, riming up of the holes, tearing of the covering
thread or the core thread by the sticking fast of a bobbin and so on.
The object of this invention is to obviate such defects.
The bobbins for the covering material consist of two separate parts viz. : an
outer bobbin or flanged sleeve made of lashing material taking up little space such
for instance as sheet metal or cardboard and serving to take the covering material
and an inner part or core. The latter always runs upon one and the same spindle ;
it is formed with an annular groove for receiving a cord by means of which the
braking is effected in the usual manner. As the inner part or core is not removed
and each spindle orly requires one such it pays to make it very carefully and well
thus securing a good fit and avoiding the aforesaid interruptions.
In order to ensure that the outer bobbin or flanged sleeve shall be properly fixed
on the inner one it is well to make the latter slightly conical and to make the outer
bobbin or sleeve slit open.
The replacing of an outer bobbin is simply effected by lifting an empty one off
the inner core and putting on a full one instead. To ensure a good connection
between the outer and the inner part a strip of paper or cardboard may sometimes
be interposed. For large bobbins such for instance as used in cable machines
special fastening screws have to be added.
Sometimes the spindle is a metal tube through which the core passes which is to
be covered. Upon this tube is mounted the pulley and upon the latter the aforesaid
compound bobbin. The covering thread passes from the bobbin over a guide pulley
to the core.
Or for other uses the spindle has outside the bobbin a tension weight guided
upon a vertical bar which also carries a movable sleeve with pawl that gears with
a ratchet wheel in the bobbin core or inner part. The thread from the tension
weight passes through an eye on a lever which is held in the horizontal position
by the thread tension.

Improvements in Machines for Covering or Braiding Over Cord,
Rope, Wire, and the like.
1, PETER JENSEN of 77 Chancery Lane, London, Chartered Patent Agent, do
hereby declare the nature of this invention (a communication to me from abroad
by Anton Kreidler of 6 Kasernenstrasse, Stuttgart, Germany, Manufacturer)
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 an improved bobbin or spool for covering or
braiding machines of all kinds, such bobbin consisting essentially of an inner or
core part forming the bobbin proper and a flanged sleeve thereon, which carries the
covering material.
As is well known, the bobbins which carry the covering material (for instance
silk, cotton or jute) in covering and braiding machines are of wood and sometimes
provided with a lateral slit for enabling the removal of same when run empty. If
the working of the machine is to be suitable the number of spare bobbins or spools
must be large and they must be kept ready filled with the covering material.
Their small size however necessitates their frequent removal. Considering that
the bobbins or spools cannot possibly be made exactly alike in all parts it is
obvious that the insertion of a fresh bobbin or spool often may cause interruptions
such as tedious adjustment of the tension, riming up of the holes tearing of the
covering thread or the core thread by the sticking fast of a bobbin and so on.
The object of this invention is to obviate such defects.
Figure 1 of the annexed drawing represents in section the principal part of a
machine for covering cord, rope and the like with the improved spool.
Figure 2 shows the inner core in elevation.
Figure 3 is a similar view of the outer part of the spool forming a flanged
sleeve.
Figure 4 represents a part of a bobbin machine for braiding cords and the like
furnished with the improved bobbin and
Figures 5 and 6 are detail views of the parts of this bobbin.
The bobbins for the covering material consist of two separate parts viz.: an
outer bobbin or flanged sleeve a made of durable or lasting material taking up
little space such for instance as sheet metal or cardboard and serving to take the
covering material and an inner part or core b. The latter always runs upon one
and the same spindle that is to say it is never removed therefrom; it is formed
with an annular groove b¹ for receiving a cord by means of which the braking is
effected in the usual manner. As the inner part or core is not removed and each
spindle only requires one such, it pays to make it very carefully and well, thus
securing a good fit and avoiding the aforesaid interruptions.
In order to ensure that the outer bobbin or flanged sleeve a shall be properly
fixed on the inner core bit is well to make the latter slightly conical as shown in
Figures 2 and 5 and to make the outer bobbin or sleeve slit open as shown for
example in Figure 3.
The replacing of an outer bobbin a is simply effected by lifting an empty one
off the inner core 6 and putting on a full one instead. To ensure a good connection
between the outer and the inner part a strip of paper or cardboard may sometimes
be interposed. For large bobbins such for instance as used in cable machines
special fastening screws have to be added.
In Figure 1 the spindle is a metal tube c through which the cord, rope or wire d
passes which is to be covered. Upon this tube is mounted the pulley e and upon
the latter the aforesaid compound spool a b. The covering thread d¹ passes from
the spool over a guide puller f to the cord, rope or wire d.

weight g, Figure 4, guided upon a vertical bar h which also carries a movable
sleeve with pawl that gears with a ratchet wheel on the bobbin, core or inner
part b. The thread from the tension weight passes through an eye on a lever k
which is held in the horizontal position by the thread tension.
A tension device of this kind works in the following manner.
According to Figure 7 of the annexed drawings which represents in a side view
a braiding machine, the covering threads d' of the single bobbin a
pass through
an eye z in the usual manner, after having passed through a hole of the vertical
bar Figure 4, as well as through the eye of the weight g and that of the lever k.
The weight is therefore lifted according to the proceeding of the braiding
process. Finally the weight g will impinge against the movable sleeve i and its
pawl is brought out of gear with the part b of the bobbin. The bobbin may
therefore turn on its axis and the thread may run down. In consequence of this
movement of the bobbin the weight g and also the pawl of the sleeve i will move
more downward again and the bobbin is prevented from turning.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim as the invention communicated to me is :-
1. A bobbin or spool for covering or braiding machines consisting of an inner
part or core 6 running always upon one and the same spindle and of an outer
detachable part a forming a flanged sleeve upon the core and carrying the covering
material substantially as set forth.
2. The constructions of bobbins or spools as shewn on the drawings.
