I FRIEDRICH EDUARD AUGUST BÜSCHE of Schwelm, Westphalia in the Empire
of Germany Manufacturer do hereby declare the nature of this invention to be
as follows:-
"
This invention has for its object a new mode of imparting a constant tension
to the bobbin threads of Braiding machines whereby such machines can be driven
at a much higher speed than has heretofore been found practicable under the
ordinary arrangement of tension weights or springs. Heretofore the maximum
of speed which could be imparted to such machines was dependent on the effect
of inertia acting on the tension weights for so soon as the speed of the machine was
increased to such an extent as to cause the weights to adhere to the sides of the
hobbin carriers according to the law of inertia, and thereby prevent their free descent,
the threads remained during the traverse of the bobbin carriers, without change and
the threads were consequently without tension, especially on the passage of the bobbin
carriers through the inner circuit of the sliding or guide plate and the braid produced
presented so unequal and defective an appearance as to be unsaleable. For the same
reason all attempts at remedying this important defect by the substitution of tension
springs for the weights also failed as the natural relaxation or slackening of the
springs during the inner traverse of the bobbin carriers produced the same
inconvenience as the periodic cessation of the action of the tension weights.
Now according to my invention I remedy. the above defects by arranging the
tension springs or weights in such a manner that they shall exert a determined
uniform tension on the threads whatever may be the position they occupy during the
working of the machine. For this purpose I use by preference a Braiding machine
of the German system and the arrangement I am now about to describe is intended
or such a machine the variation in the arrangement which will be imparted to
he other forms of braiding machines will readily be understood by analogy. The
ower end of the spring is attached a small sliding block inside the tubular bobbin
carrier which carrier is provided at its lower portion with two longitudinal slots on
pposite sides through which and through the sliding block there is passed

page_text: transversely a pin which projects from opponite sides of the bobbin carrier. Upon
the pivots which carry the notched disc wheels there are mounted bosses formed with
double or continuous inclined surfaces the amount of inclination being in proportion
to the shortening or contraction of the threads produced during the passage of the
bobbin carriers from the outer towards the inner portion of the slotted guide plate.
The said inclined surface is repeated on each side of the boss in such a manner that
the highest point in the inclined path shall correspond to the suminit of the exterior
circuit of the bobbin carrier and the lowest point to the summit of the interior circuit.
The projecting end of the aforesaid pin passes under the said inclined surface and both
are bevelled in order to ensure the certain engagement of the pin under the inclined
path of the succeeding boss before quitting the previous one, even in the least
favourable positions of the bobbin carriers, that is to say whilst they are passing
from the interior towards the exterior of the guide plate. The uniform action which
the springs exert upon the bobbin threads is due to their change of position produced
by the action of the inclined surfaces upon the sliding blocks in proportiou to
the shortening or contraction of the threads. The same arrangement is equally
applicable to tension weights instead of springs but where I use weights I would by
preference arrange the bosses with inclined grooves or slots (instead of the inclined
surfaces) wherein the said pins of the sliding blocks may travel with a certain
free play.
According to a modified arrangement the pivot carrying the notched disc wheel
is bored for the free passage through it longitudinally of a sliding spindle which
receives an up and down movement by being connected at its lower end by an arm
to a second vertically sliding spindle the upper end of which is provided with a pin
acted upon by a double or continuous incline on the boss of the notched disc wheel.
A horizontal disc or semicircular projection is connected with the upper end of the
first mentioned vertically sliding spindle and moves up and down along with it and
this disc by acting upon the pin in the sliding block of the bobbin carrier governs or
controls the action of the spring or tension weight as the case may be.
If desired the vertical movement of the spindle inside the pivot which carries the
notched disc wheel may be produced by mechanical means, entirely independent
of the notched disc wheel, so as to regulate as required the raising or lowering of the
aforesaid disc which acts upon the pin of the tension spring or weight. This
disc is by preference of a semicircular form in order that it shall only operate during
the inner circuit of the bobbin carriers.
According to another modification which may be used in those cases where
a uniform tension of the threads in the extreme position of the bobbin carriers, (that
is to say at the opposite summits of the notched disc wheels or at the crossing points)
may be sufficient.
In this arrangement the acting inclines are fitted only to the inne
side of the slotted guide plate in such a manner that their inclination shall permit o
the free engagement therewith of the beforementioned cross pins when the sliding
block inside the bobbin carrier, is in its highest position which position should
be limited when using tension springs. The inclination of the inclined planes may
also be limited if desired by arranging the sliding block in such manner as to produce
the effect of a differential pulley. Also the weight of the sliding block itself with it
cross pins, may if found desirable be counterbalanced by the action of a spring
arranged underneath the sliding block or otherwise.

page_text: Improvements in Braiding Machines.
I FRIEDRICH EDUARD AUGUST BUSOHE of Schwelm, Westphalia in the Empire of
Germany, 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 :—
My invention relates to the tension devices for imparting the required tension to the
bobbin threads in braiding machines for any kind of braid and containing any number
of bobbin carriers.
The ordinary tension devices heretofore employed in braiding machines cease to
impart a uniform tension to the threads after a certain rate of speed is exceeded and
hence they have the effect of limiting the speed at which the machine can be efficiently
worked as its maximum speed is dependent on the effect of inertia acting on the tension
weights, for so soon as the speed of the machine is increased to such an extent as to
cause the tension weights to adhere to the sides of the bobbin carriers according to the
law of inertia the free descent of the weights is prevented and the threads are conse-
quently left at intervals of time without any tension especially during the passage of
the bobbin carriers through their inner circuit hence the braid produced in such
machines when driven at a speed exceeding the maximum above referred to prosented
so defective an appearance as to be unsaleable.
The substitution of tension springs for tension weights failed to remedy this important
defect because the natural relaxation of the tension springs during the inner traverse
of the bobbin carriers produced the same defect in the braid as the periodic cessation
of the action of the tension weights.
The present invention has for its object:
First, to provide improved means whereby a determined uniform tension may be
imparted to the bobbin threads of a Braiding machine at whatover speed it may be
driven and whatever may be the position which the bobbin carriers of such threads
occupy during the working of the machine with a view to enabling the machine to be
driven at a higher speed than has heretofore been found practicable without injuriously
affecting the quality of the braid produced, and to this end my invention consists in
providing the machine with as many spiral or inclined cam surfaces as it contains
notched disc wheels or drivers which spiral or inclined cam surfaces are inclined in
proportion to the shortening or lengthening of the threads to which they are subject
during the passage of the bobbin carriers on the corresponding notched disc wheels or
drivers and act directly or indirectly upon projecting pins fitted into sliding blocks or
sleceves attached to the lower ends of their corresponding tension springs inside the
bobbin carriers imparting a positive upward and downward movement to the tension
springs and their thread eyes in proportion to the shortening or lengthening of the
threads. When tension weights are used instead of springs the projecting pins are
fixed directly to the weights themselves the sliding blocks being in that case dispensed
with.
These Tension springs when employed in conjunction with inclined cam surfaces
for imparting a positive upward and downward movement thereto as herein before

page_text: described are subjected to considerable wear and tear by their friction against the sides
of the bobbin carriers whereby the original strength of the springs would be impaired
and the braid produced would become consequently defective.
It is therefore desirable to provide means whereby the original strength of the
tension springs may be maintained.
To this end as a developement of and in combination with the improvements set
forth in my provisional specification I provide protecting discs rings or collars at both
ends of the spring which prevent all friction between the spring and the inner sides of
the bobbin carrier and such tension springs with the said collars may further be
surrounded by a light protecting tubular sheath fixed to the thread eye of the spring
or its upper collar the sheath being long enough to cover also the lower collar of the
spring even when in full tension during its work. Or the upper collar of the spring
or its thread eye may be connected with a side bar passing along one side of the
spring and its collars and bent at right angles at its lower end affording free passage
to the wire which connects the lower collar of the spring with the before mentioned
sliding block inside the bobbin carrier but not allowing the lower collar to pass beyond
it thus preventing the spring from being drawn out beyond its range and consequently
protecting it from injury by carelessness on the part of the workman. The same
arrangement also prevents the spring when detached from its sliding block from
thoroughly contracting which if frequently repeated might also prove detrimental to
the spring.

Similar letters refer to similar parts throughout the several views: -
A is a portion of the bed plate and B a portion of the top or guide track plate of an
ordinary German braiding machine. a' is the bobbin mounted on the tubular bobbin
carrier or traveller a. hhare the notched disc wheels or drivers mounted so as to turn
freely on the stud pins f fixed to the bed plate A and r are the gear wheels through

page_text: which the rotary motion of the notched disc wheels or drivers is effected and transmitted
all of which parts are well understood by those familiar with braiding machines. e is
the tension spring of my improved tension device provided at its upper end with the
usual thread eyes and attached at its lower end to a block b sliding freely inside the
tubular bobbin carrier. The adjustment of the tension of each spring separately may
be effected in any well known manner, thus either the lower end of the spring may be
connected with a small winding barrel or spindle e' in the sliding block b as shown
clearly in figures 3, 8, 9, and 11 or which I prefer the lower end of each tension
spring may be attached directly to its sliding block by a simple wire ring or eye or in
any other convenient manner. The distance between the sliding block 6 at the lower
end of the tension spring e and the thread eyes at the upper end of the spring is
always the same in the saine machine-This distance is indicated by the position on
the one part of the thread eye just beneath and in contact with the spool catch n
(figures 1 and 8) so as to be ready to disengage it, and the position on the other part
of the block 6 when at its highest point in the bobbin carrier which latter position it
assumes when the bobbin carrier is at the outer side of the guide track plate as shown
in figures 3 and 8. It will therefore be readily understood that the tension of each
spring can be perfectly regulated by shortening or lengthening the connecting wire
or the wire eye between between the block 6 and the lower end of the spring e but
the mode of adjusting or regulating the tensions of the springs forms no part of my
present invention.
The lower part of the tubular bobbin carrier is formed with two longitudinally
disposed slots & one on each side thereof through which slots and through the sliding
block there is passed transversely a pin c which projects beyond the sides of the
bobbin carrier and works up and down in the said slots. In order to impart still
more steadiness to the pin c it may be provided with a sliding collar or sleeve 6 as
shown in figure 3* outside the tube of the bobbin carrier a and surrounding it closely
but free to slide up and down the said tube. By the employment of this outside
sliding collar or sleeve 6" the internal sliding block may be dispensed with. One of
the projecting ends of the pin c passos under and is maintained in contact with a
double continuous inclined or spiral cam surface or path g₁ formed on a cylindrical
boss or sleeve a fixed upon the upper ends of cach of the stud pins which carry tho
drivers and their gear wheels there being as many of these bosses with inclined
cam paths as there are drivers in the machine. The upper ends of the said stud pins f
are caused to project through and above the surface of the top or. guide track plate B
in order to receive the sleeves or bosses g. Instead of extending the pins fabove the
guide track plate separate studs may obviously be employed which will then be screwed
to the upper ends of the pins f. The amount of inclination or rise and fall of the
continuous inclined cam surfaces or path g' which surrounds each sleeve or boss should
correspond to the amount of shortening of the threads produced during the passage of
the bobbin carriers from the exterior towards the interior of the guido track plate.
The said inclined surface or path is repeated on each side of the boss
or sleeve g which is so adjusted that the highest point of its inclined
path shall correspond to the summit of the exterior circuit of the bobbin
carrier and the lowest point to the summit of the interior circuit of the bobbin
carrier. In order to ensure with greater certainty the engagement of the pin c under
the path g¹ of the next succeeding boss or sleeve g before quitting the previous one
(even when the bobbin carrier is in its least favourable position or whilst in the act of
passing from the interior towards the exterior of the guide track plate) the
corresponding parts of the surface of the inclined path gas well as the pins care
bevelled. The uniformity of the tension imparted by the springs e to the bobbin
threads is due to the change in the vertical position of the said springs produced by
the action of the inclined surfaces g' upon the projecting pins c in the sliding blocks b
or in the outer sliding collars or sleeves the amount of such displacement or
vertical movement being always in proportion to the amount of shortening or
lengthening of the threads.
In the modification shown in elevation and plan at figures 4 and 5 the projecting

page_text: pin c of the sliding block 6 in lieu of being acted upon directly by the inclined cam
surface or path g¹ of the boss g is acted upon by a disc or semi disc k¹ formed on one
side of a cap which is fixed to the upper end of a rod i sliding vertically in the
tubular stud pin which carries the driver h the cap k sliding up. and down over
the projecting upper end of the tubular stud pin and the semi disc k¹ projecting over
the end of the pin c in the sliding block. The lower end of the vertically sliding rod i
is rigidly connected by the arm to a rod m¹ which slides vertically through a guide
bush u screwed into the bottom plate A of the machine. A lateral projection or pin m
on the upper end of the sliding rod m³ is held in contact with the inclined cam surface g¹
by the downward pressure of the helical spring which surrounds the rod m'. This
inclined cam surface in lieu of being stationary and mounted on the upper end of the
stud pin or pivot f of the driver is caused to rotate it being formed in one with or
attached to the boss h¹ of the driver and gear wheel r. As the pin m rises up the
interior of the revolving cam surface g¹ the rod m' is lifted and with it the rod i cap k
and semi-disc thereby allowing of the upward movement of the sliding block with
its pin c.
As the bobbin carrier a is shown in elevation in figures 4 and 6 the sliding
block itself is not seen. When the pin m descends along the inclined cam surface a
downward motion is imparted to the semi-disc k¹ by the action of the helical spring vand
as the projecting pin c passes under the edge of the semi disc k¹ during the traverse of
the bobbin carrier the sliding block will be caused to descend to the extent of the
inclination of the cam surface g¹ that is to say in proportion to the amount of
slackening of the thread the shortening of which draws up the tension spring again
and with it the sliding block and pin c. I prefer the semicircular form of disc
order that it may act upon the pin c of the sliding block during the inward traverse
only of the bobbin carrier.
in
The further modification of my improved spring tension device shown in
figures 6 and 7 may be advantageously employed in those cases where a uniform
tension of the threads in the extreme positions of the bobbin carriers (that is to say at
the diametrically opposite sides or summits of the notched disc wheels or drivers h
or at the intercrossing points) may be deemed sufficient or where a peculiar form of
the guide track prevents the use of the former arrangements. In this modification
1 substitute for the cylindrical boss or sleeve g before described fixed inclined cam
surfaces curved in plan to suit the circular course of the pins c and which are
attached to and project over the edge of a supporting plate or bar w situate above the
inner side of the guide track plate B so that the projecting pins c of the sliding blocks
shall be acted upon by the said fixed inclines g' when the sliding blocks are in their
most elevated position in the bobbin carriers. It is obvious that such an arrangement
can also be used in combination with the arrangement of the cylindrical boss g fixed
on the pivots f.
g
Figure 8 is a further modification of my improved spring tension device wherein
the cylindrical boss or sleeve 9 has its inclined path or cam surface gl so disposed that
the pin c of the sliding block 6 shall rest upon the upper in lieu of upon the under
surface of the said inclined path as described with reference to figuro 3.
In this modification a second spring 1 of greater strength than the tension spring e
is attached at its upper end to the underside of the sliding block b and at its lower
end to the bottom of the bobbin carrier the object of this spring being to draw
downwards the block b and to maintain the pin c in constant contact with the inclined
cam surface g'. In no other respects does this modification differ from the arrangement
shown in figure 3.
In the modified arrangement of spring tension device shown in figure 9 a spring
in the lower part of the bobbin carrier presses upwards against the sliding block b and
tends to raise it keeping the pin c always in contact with the underside of the inclined
cam surface g¹ in the boss g thereby overcoming any inertness in the sliding block b
in case the weight of the latter be too heavy in proportion to the strength of the
tension spring e. Although at certain speeds of working tension weights may be
employed in connection with the same controlling arrangements that I have described
with reference to tension springs (Figures 8 and 9 excepted) I find it more

page_text: advantageons when using tension weights to employ the arrangement shown at Figure 10
in which an inclined groove or slot y' is provided in the cylindrical boss or sleeve g
in lieu of the simple inclined path or surface shown in figure 3. The said inclined
groove or slot should be of a sufficient width to allow of a certain amount of free play
to the pin c therein. The sliding block in this arrangement is dispensed with as the
pin c is passed through the lower portion of the weight e" itself. The inclined groove
or slot g¹ is preferable because the inertness of the tension weight e" will also have to
be taken into consideration when the tension weight is to be raised during the traverse
of the bobbin carrier from the inner towards the outer portion of the guide track plate
and the wide slot or groove in the boss g will be better adapted for giving continually
slight pushes to the weight to overcome the effect of inertia. It is obvious that the
cam groove ginust allow the weight e" to be sufficiently raised (the bobbin carrier
being at its outer position) to disengage the spool catch n not only for the purpose of
allowing the thread to run off in the well known manner but also for allowing the
spool thread to be passed through the eyes of tho tension weight consequently the
cam surface should be higher at the outer side than would be required for a tension
spring in order to ensure the sufficient lifting of the weight.
The well known appliance for stopping the braiding machine when a thread is
broken or run off its bobbin will be used in connection with the tension devices
Figures 8, 9, and 10 although not shown in those figures. Such an appliance is
however shown at x in the first described arrangement of spring tension device
illustrated in figures 1 and 2, but as it is well known to those familiar with braiding
machines I have not considered it necessary to mako further reference thereto. The
projecting pins c of the spring tension devices illustrated by Figures 1 to 7 inclusive
may also be made to act upon the usual stop or disengaging mechanism of the
braiding machine provided the longitudinal slots tt in the bobbin carriers bo of
sufficient length to allow the sliding block 6 to descend far enough to bring the pins c
in contact with such stop mechanism.
In order to protect the thread tension springs of my improved braiding machines
from wear and tear by friction against the inner sides of the bobbin carriors whereby
the springs become damaged and of different strength and the regularity of the braid
is greatly impaired, I combine with the tension springs e thereof a disc or collar y y' at
each end as shown in Fig. 11; the upper disc or collar y may be directly connected
with the thread eyes said collars being of larger diameter than the spring e so that when
touching the inner sides of the tubular bobbin carriers a in their free rise and fall
therein they will prevent the spring itself from coming into contact with the inner
sides of the bobbin carriers and thus avoid wear and tear of the spring by friction.
This arrangement may be further improved by the combination therewith of a light
protecting tubular sheath of vulcanito or other suitable material fixed to the thread
eye or to the upper disc or collar y of the spring, in any convenient manner and
surrounding the spring throughout its entire length along with lower its disc or
collar y even when in full tension during the work. The said lower collar y must of
course be free to rise and fall inside the tubular sheath z and the latter must also be
free to rise and fall inside the bobbin carrier a along with the tension spring.
In the modified and still more improved arrangement shown at figure 12 I combine
the said tension springs e and their discs or collars y y¹ with a side bar z' passing
along one side of the spring and bent at a right angle at its lower end through an
opening in which bent part the wire connecting the lower collar y' of the spring with
the sliding block 6 can pass freely but which prevents the said lower collar from being
drawn beyond it thus limiting the full extension of the spring in such a manner that
the spring itself cannot be injured by being drawn out by the attendant farther than
its elasticity would fairly allow. This arrangement further serves to prevent the full
contraction of the spring which by frequent repetition might also prove injurious to
the quality of the spring.
Although I have only shown and described the arrangements for raising
and lowering the tension springs or weights in proportion to the shortening or
lengthening of the threads in a Braiding machine with bobbin carriers as applied to

page_text: what is commonly known as the German Braiding Machine the same may be equally
well applied to the other varieties of Braiding machines and bobbin carriers in use and
any alterations that may be required in adapting my said improvements to other well
known types of braiding machines and bobbin carriers will be readily understood by
those familiar with such machines from the description already given.
