PROVISIONAL SPECIFICATION.
Improvements in Chenille Machines.
I, CARL KNAUER, of Apolda, Germany, Upholsterer, do hereby declare the
nature of this invention to be as follows:-
This invention relates to improvements in the construction of chenille machines,
whether for producing cut or uncut chenille, which have for their object firstly to
do away with the necessity for a moveable carriage and rails therefor, which take
up considerable space, and secondly to enable both uniformly twisted chenille to be
produced in great lengths, as also to enable the degree of twist to be regulated
according to the nature of the material employed.
The accompanying drawing shews my improved construction of chenille machine
for the production of cut chenille; Fig. 1 shews a side view, Fig. 2 a front view,
Fig. 3 a back view, and Fig. 4 a plan.
Figs. 5 to 10 shew detached details. The framing of the machine consists
essentially of the uprights a and the horizontal beams b, forming a lower and an
upper frame. From the right hand end, Fig. 1, there is introduced between the
first pair of uprights aa further horizontal beam 1 between and parallel to the
beams, and which are fixed to a. On these beams are carried the bearings of
the driving shaft A¹ carrying a strap-, cord-, or chain-pulley A from which the
pulley m of the shaft m is driven by means of the endless cord or chain B. The
pulley m has several grooves, in one of which is placed an endless cord / which is
led over guide pullies n n on the framing to the two winding-on mechanisms C at
the left hand end of the machine so as to drive these. To the right of the latter,
Fig. 1, are also two mechanisms D arranged side by side, for twisting, these
mechanisms being driven by an endless cord 'passing over guide pullies n' n¹
fixed to the framing.
The winding-on mechanisms C as also the mechanisms D for twisting are carried
by cross bars e resting on longitudinal rails c'.
The winding-on mechanism C is shewn detached in longitudinal section in Fig. 5,
and contains a spindle d the bearings e of which are fixed to the framing c. The
spindle is made tubular at the right hand end, the hollow being made to extend
somewhat beyond the speed-pulley, fixed or formed thereon.
Between the latter and an army fixed to the spindle, a longitudinal slot do is
formed in the spindle d and in this slot is placed a pulley 1. The arm g one part
of which is radial while the other part runs parallel with d, and which is situated in
the plane of the pulley 1, carries several pullies 22 rotatable in the same plane
as 1.
Within the cylindrical space described by the rotation of g is a bobbin / mounted
loose on the spindle d, and having several grooves h¹ in one of which is placed a
cord i, the ends of which are attached to a freely suspended weight k. The
spindle d is driven by the cord from the pulley m.
The mechanism D for twisting which is shewn in Figs. 6, 7 and 8 in longitudinal
and cross section and plan, consists essentially of a hollow spindle d' rotated in
bearings el, by means of the endless cord passing round a speed-pulley f¹ thereon.
An arm g fixed to this spindle d' and which is partly radial and partly parallel to
the spindle, carries at the end of the latter part, which is directed away from the
pulley, two pullies 5 and 6.
Within the cylindrical space described by the rotation of this arm is situated a
drum o, rotatable on the spindle d', the surface of which is roughed, for the
purpose hereinafter explained, and which is fixed to the grooved pulley p.

page_text: mis puney P nas a cora passing partly round it, the two ends of which are
attached to a free hanging weight k¹.
In the part of the hollow spindle between the speed pulley and the arm g' is
formed a longitudinal slot d' at each end of which is a roller 3 and 4. The formed
but unspun chenille passés through the hollow spindle d' from holes in the arms 23
on the right hand side of the mechanism D, and is led over the roller 3 to the
roller 5 on the arm and from this it passes round part of the circumference of the
drum o and thence to the roller 6.
From the latter the chenille is passed over roller 4 to the interior of the spindle d'
through which it is then led to the winding-on arrangement C.
The winding on apparatus C and the twisting mechanism D operate in the
following manner.
The chenille coming from the arm 23 becomes twisted together at that part
between 23 and the spindle d', in consequence of the rotation of the latter and of
the fact that the chenille passes from the roller 3 in an inclined direction to
the roller 5, thereby forming a crank arm, at the same time passing between knives
to be presently described, which cut the chenille, the latter being held stretched by
the winding-on apparatus C and by the drum o as will be presently explained.
1.
14.
At the same time assuming that for the moment no forward feed of the chenille
takes place, the drum o will be rotated in consequence of the fact that the chenille
cannot slide upon its roughened surface, such rotation taking place at the same
speed as that of the hollow spindle and in consequence hereof the cord is made
to slide over the pulley p. If, however, the chenille is fed forward so that,
in consequence of the corresponding lengthening thereof, a pull is exerted on the
circumference of the drum o which produces the friction exerted at the circum-
ference of the pulley p' and which causes the drum o to be retarded in its rotation
to an extent corresponding to the forward feed, then such a shifting of the drum o,
relatively to the spindle d¹, will take place, that the tension of the chenille between
the said knives and the roller 3 will be further increased. By regulating the size
of the weights kk a greater or less tension of the chenille can be effected, as
by this means the degree of the brakeing of the pullies p and will be varied.
This brakeing of the pullies p and h¹ may also be effected by means of springs or
equivalent appliances in place of weights. The bobbin h of the winding-on
apparatus will generally stand still in consequence of the friction produced by the
cord i which is placed in one of the grooves of ', so that the arm g that revolves
round the bobbin / will wind the chenille on to the latter. If, however, a tension
occurs in the chenille which can be overcome by the frictional resistance produced
by the cord i, no further chenille will be wound on. The more or less tight
winding on of the chenille can therefore be controlled by attaching a larger
or smaller weight or by placing the cord with the weight k from a smaller upon
a larger groove of h', or vice versa. In the last described manner the resistance of
the drum o of the twisting apparatus can also be varied. The action of the two
weights and assist each other reciprocally, as a drawing back of the chenille
can only occur when an unwinding thereof from the bobbin ½ takes place. There
may however be exerted an increased resistance by an increased brakeing action on
the bobbin as compared with that on the drum o if required, because the chenille
that has been wound on attains gradually an increased' circumference, whereby
a drawing back of the chenille will be prevented. The winding on of the chenille
which prevents the subsequent kinking thereof can be effected' by allowing the
winding on apparatus C to run somewhat slower than' the twisting apparatus D.
The winding on apparatus C may also be employed for the twisting process without
having a separate appliance for this purpose.
I will now describe the right hand part of the chenille machine shewn in Fig: 1.
It contains the device E for connecting the threads, for cutting the same, and' for
feeding the same forward. The device E for combining the threads which is shown
partly in side view and partly in longitudinal section at Fig. 9' and' in front view at
Fig. 10, consists of a bobbin carrier 7, which' rotates upon' a' hollow axis 8, being

page_text: driven by an endless cord 9. The latter passes over guide rollers 10 and IU' and 18
driven from the pulley m. The bobbin carrier 7 is provided, as in the example
shown, with two bobbins 11 which are mounted rotatable on spindles and are
From each of these
prevented from rotating freely by means of spring brakes 12.
a thread 13 passes off to the left. These threads are supported by a ring 14
connected by arms 15 with the cylindrical boss of the bobbin carrier 7, the ring
being stationary but adjustable in position. This ring 14 has in the present case a
central circular hole through which a tongue 16 of rectangular section extends
some distance to the left. This tongue 16 is connected by pins with the hollow
axis 8, so that on the rotation of the bobbin carrier 7 the threads 13 are coiled
round the part of the tongue 16 projecting to the left beyond the ring 14. Along
each vertical side of this tongue passes a warp thread 17 while between the latter
and the tongue 16 two wires 18 pass, perpendicularly one above the other. The
correct position of these warp threads and wires is secured by forming the tongue 16
at the sides with longitudinal grooves 16¹ while the feed of these parts, to be
presently described, is effected in such manner that first the wires 18 are applied to
the grooves 16 and afterwards the warp threads 17. After the warp threads 17
and wires 18 held by the tongue 16 have been wound round with the weft
threads 13, as above described, such wound part of the tongue moves to the left,
and the knife 19, to be presently described, comes into action by cutting the weft
threads as may be desired between the wires 18. The cut threads thus produced
which are carried by the warp threads 17 and 21 are in the first place pressed by
the wires 18' against the rollers 22. The wires 18 afterwards both run over
rollers 20 in a direction which is different from that of the warp threads 17. The
latter are now joined by other warp threads 21 which pass over the rollers 22.
The two warp threads 17 and 21 which hold between them the cut threads
produced by the thread 13 pass, after having been somewhat twisted by the
mechanism D, through the openings of the adjustable arms 23 and into the
twisting mechanism D in order to be operated upon thereby in the above described
manner.
The connection of the fixed hollow axis 8 with the framing is effected by
casting 24 carried by two horizontal bearers b. On this casting 24 there are
mounted the rollers 22 with spring action in such manner that they are
automatically pressed against the tongue 16. They are for this purpose mounted
rotatably near the middle of arms 25 which are pivoted upon a pin 26 at one end
thereof while the other end is acted upon by a spring 27 connected to both arms.
The casting 24 also has a vertical hole 24' in which is mounted the knife carrier 28
and also the knife 19 in a rotatable manner. To the lower end of the knife
carrier 28 which passes through the casting is attached a rocking arm 30. To the
other end of this rocking arm is connected a rod 32 with a slotted connection 31,
the other end of such rod being connected in a similar manner to the rocking
arm 33. The latter rocks upon a pivot 34 on the framing and the free end thereof
is acted upon by a cam 35. This cam is fixed on a shaft 36 carried by the framing
and receives its motion by means of the cord pulley 37 on the latter which is driven
from another pulley 38 on the driving shaft A¹ by means of an endless cord 39
which is led over adjustable guide rollers 40 and 41. During the continuous
forward motion of the warp threads, wires and weft threads, the fixed knife 19 cuts
the weft threads as these are presented to it. If, however, shaped chenille is to be
produced, the above named parts 19, 28, 30, 32, 33, 35, 37, 38, 40 and 41 are
driven by the cord 39. In consequence hereof, the knife carrier 28 will be turned
in the casting 24 to the right or to the left according to the cam 35. The knife 19
carried by the knife carrier 28 between the wires 18 then effects the cutting of the
weft threads from the centre of the knife carrier 28 in circular arcs to the right and
to the left. The shape of the chenille is consequently dependent upon the form or
size of the cam 35, the cord pullies 37 and 38 and the connecting rods 30, 32
and 33. The forward feed of the warp thread 17 is effected in such a manner that
in passing each from a bobbin 42 at the rear end of the machine they are led each

page_text: by a roller 43 into the hollow axis 8. The warp threads 21 pass each from a
bobbin 44, and passing over a guide roller 45 which is adjustable relatively to the
casting 24, they pass to the above named rollers 22. The speed of the bobbins 42
as also of those 44 is regulated by weights 421 and 44' which exert a tension upon
a cord 42° and 44° passing into a groove of the bobbin. The warp threads are
thus wound off to an extent corresponding to the pull exerted by the twisting
apparatus. The wires 18 on the other hand are fed forward by toothed wheel
transmission the first wheel of which, 46, is fixed on the driving shaft A'. By
means of the intermediate wheels 47 to 52, the rotary motion of the driving
shaft 46 is transmitted to a shaft 53 carried in bearings at the rear of the upper
end of the chenille machine. On this shaft 53 is a pulley 54 having five grooves.
In the same plan with and at the same height as the pulley 54 there is a second
pulley 9 on the side of the rollers 20 opposite to 54, and which has only four
grooves. Round these pullies 54 and q the wires 18 are made to travel several
times, the upper ends situated between the rollers being made to pass through the
hollow axis 8, the tongue 16, as also the rollers 20 and 22, the wire being made to
pass from a bobbin 56 at the rear end of the machine into the first groove of the
pulley 54, while the part of the wire running off the fifth groove of this pulley is
wound up on a bobbin 57 arranged by the side of 56, but which is driven from the
shaft 53 by means of pullies 58 and 59 and an endless cord 60.

COMPLETE SPECIFICATION.
Improvements in Chenille Machines.
I, CARL KNAUER, of Apolda, Germany, Upholsterer, 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 relates to improvements in the construction of chenille machines,
whether for producing cut or uncut chenille, which have for their object firstly to
do away with the necessity for a moveable carriage and rails therefor, which take
up considerable space, and secondly to enable both uniformly twisted chenille to be
produced in great lengths, as also to enable the degree of twist to be regulated
according to the nature of the material employed.
The drawing accompanying my Provisional Specification shews my improved
construction of chenille machine for the production of cut chenille; Fig. 1 shews a
side view, Fig. 2 a front view, Fig. 3 a back view, and Fig. 4 a plan. Figs. 14, 44
and 5 to 10 shew detached details to an enlarged scale.
The framing of the machine consists essentially of the uprights a and the
horizontal beams b, forming a lower and an upper frame. From the right hand
end Fig. 1, there is introduced between the first pair of uprights
a a farther
horizontal beam 61 between and parallel to the beams b, and which are fixed to a.
On these beams are carried the bearings of the driving shaft A' carrying a strap,
cord, or chain pulley A from which the pulley m² of the shaft m is driven by means
of the endless cord or chain B. The pulley m has several grooves, in one of which
is placed an endless cord which is led over guide pullies n n on the framing to the
two winding-on mechanisms C at the left hand end of the machine so as to drive
these. To the right of the latter Fig. 1, are also two mechanisms D arranged side
by side, for twisting, these mechanisms being driven by an endless cord passing
over guide pullies n' n¹ fixed to the framing. The winding-on mechanisms Cas
also the mechanisms D for twisting are carried by cross bars c resting on longitudinal
rails c¹.
The winding-on mechanism C is shewn detached in longitudinal section in Fig. 5
and contains a spindle d the bearings e of which are fixed to the framing c c. The

page_text: spindle d is made tubular at the right hand end, the hollow being made to extend
somewhat beyond the speed pulley f fixed or formed thereon.
Between the latter and an arm g fixed to the spindle, a longitudinal slot d, is
formed in the spindle d and in this slot is placed a pulley 1. The arm
one part
of which is radial while the other part runs parallel with d and which is situated
in the plane of the pulley 1, carries several pullies 2, 2 rotatable in the same plane
as 1.
Within the cylindrical space described by the rotation of g is a bobbin / mounted
loose on the spindle d and having several grooves in one of which is placed a
cord, the ends of which are attached to a freely suspended weight k. The
spindle is driven by the cord from the pulley m.
The mechanism D for twisting which is shewn in Figs. 6, 7 and 8 in longitudinal
and cross section and plan, consists essentially of a hollow spindle d' rotated in
bearings e by means of the endless cord passing round a speed pulley "thereon.
An arm fixed to this spindle and which is partly radial and partly parallel to
the spindle, carries at the end of the latter part, which is directed away from the
pulley, two pullies 5 and 6.
Within the cylindrical space described by the rotation of this arm is situated a
drum e,
rotatable on the spindle d', the surface of which is roughed, for the purpose
hereinafter explained, and which is fixed to the grooved pulley p.
P
This pulley has a cord passing partly round it, the two ends of which are
attached to a free hanging weight k¹.
In the part of the hollow spindle between the speed pulley f¹ and the arm ¹ is
formed a longitudinal slot d', at each end of which is a roller 3 and 4. The
formed but unspun chenille passes through the hollow spindle d' from holes in the
arms 23 on the right hand side of the mechanism D, and is led over the roller 3 to
the roller 5 on the arm g, and from this it passes round part of the circumference of
the drum o and thence to the roller 6.
From the latter the chenille is passed over roller 4 to the interior of the spindle d¹
through which it is then led to the winding-on arrangement C.
The winding-on apparatus C and the twisting mechanism D operate in the
following manner.
The chenille coming from the arm 23 becomes twisted together at that part
between 23 and the spindle d¹ in consequence of the rotation of the latter and of
the fact that the chenille passes from the roller 3 in an inclined direction to the
roller 5, thereby forming a crank arm, knives to be presently described, having
previously cut the chenille, the latter being held stretched by the winding-on
apparatus C and by the drum o as will be presently explained.
At the same time, assuming that for the moment no forward feed of the chenille
takes place, the drum o will be rotated in consequence of the fact that the chenille
cannot slide upon its roughened surface, such rotation taking place at the same
speed as that of the hollow spindle and in consequence hereof the cord is
made to slide over the pulley p. If however the chenille is fed forward so that in
consequence of the corresponding lengthening thereof, a pull is exerted on the
circumference of the drum o which produces the friction exerted at the circum-
ference of the pulley p and which causes the drum o to be retarded in its rotation
to an extent corresponding to the forward feed then such a shifting of the drum o
relatively to the spindle will take place that the tension of the chenille between
the said knives and the roller 3 will be further increased. By regulating the size
of the weights a greater or less tension of the chenille can be effected, as by
this means the degree of the brakeing of the pullies p and h' will be varied.
P
This brakeing of the pullies p and may also be effected by means of springs or
equivalent appliances in place of weights.
The bobbin of the winding-on apparatus will generally stand still in consequence
of the friction produced by the cord i which is placed in one of the grooves of h¹, so
that the arm that revolves round the bobbin will wind the chenille on to the
latter. If however, a tension occurs in the chenille which can be overcome by the

page_text: frictional resistance produced by the cord i no further chenille will be wound on.
The more or less tight winding on of the chenille can therefore be controlled by
attaching a larger or smaller weight or by placing the cord with the weight k
from a smaller upon a larger groove of ', or rice versa. In the last described
manner the resistance of the drum o of the twisting apparatus can also be varied.
The action of the two weights and assist each other reciprocally as a drawing
back of the chenille can only occur when an unwinding thereof from the bobbin /
takes place. There may however be exerted an increased resistance by an increased
brakeing action on the bobbin h as compared with that on the drum o if required,
because the chenille that has been wound on attains gradually an increased circum-
ference whereby a drawing back of the chenille will be prevented.
The winding on of the chenille which prevents the subsequent kinking thereof can
be effected by allowing the winding on apparatus C to run somewhat slower than
the twisting apparatus D. The winding on apparatus C may also be employed for
the twisting process without having a separate appliance for this purpose.
I will now describe the right hand part of the chenille machine shewn in Figs. 1
and 4, and to an enlarged scale at Figs. 1 and 4*. It contains the device E for
connecting the threads for cutting the same, and for feeding the same forward.
The device E for combining the threads which is shewn partly in side view and
partly in longitudinal section at Fig. 9 and in front view at Fig. 10 consists of a
bobbin carrier 7, which rotates upon a hollow axis 8, being driven by an endless
cord 9. The latter passes over guide rollers 10 and 10' and is driven from the
pulley m. The bobbin carrier 7 is provided, as in the example shewn, with two
bobbins 11 which are mounted rotatable on spindles and are prevented from
rotating freely by means of spring brakes 12. From each of these a thread 13
passes off to the left. These threads are supported by a ring 14 connected by
arms 15 with the cylindrical boss of the bobbin carrier 7, the ring being stationary
but adjustable in position. This ring 14 has in the present case a central circular
hole through which a tongue 16 of rectangular section as shewn to an enlarged
scale at Fig. 10ª extends some distance to the left.
This tongue 16 is connected by pins with the hollow axis 8, so that on the rotation
of the bobbin carrier 7 the threads 13 are coiled round the part of the tongue 16
projecting to the left beyond the ring 14. Along each vertical side of this tongue
passes a warp thread 17 while between the latter and the tongue 16 two wires 18
pass perpendicularly one above the other. The correct position of these warp
threads and wires is secured by forming the tongue 16 at the sides with longitudinal
grooves 16' while the feed of these parts, to be presently described, is effected in
such manner that first the wires 18 are applied to the grooves 16' and afterwards
the warp threads 17.
As the weft threads 13 are wound upon the stationary tongue 16 by the rotation
of the spool carrier, they are at the same time applied against the warp threads 17
and wires 18, which in consequence of their motion to be presently described have
the tendency to move laterally out of the grooves 16' of the tongue 16, and are only
prevented from this by the weft threads 13 wound thereon. The frictional contact
thus produced between the warp threads and the wires, on the one hand, and the
coils of the weft thread on the tongue 16 on the other hand, cause the wires and
warp threads as they advance to the left Figs. 4 and 9 to carry forward with them
along the tongue the said coils of weft thread, at the same speed as that at which
the fresh coils are wound on by the rotation of the spool carrier 7.
The warp threads 17 and wires 18, as also the coils of weft thread carried along
thereby in advancing pass between two rollers 22 Figs. 4 and 10, in a circular
groove of which is situated a further warp thread 21, which is led by 22 to the
others as will be presently described. These warp threads 21 are applied to the
outer side of the weft thread coils as at Fig. 10, and after the cutting of the weft
thread are led together with the threads 17 and wires 18 from the roller 22 in a
direction inclined from the centre line of the machine, as shewn at Fig. 4, so that
all the threads and wires in passing away are applied closely to the groove of 22.

page_text: This fact, as also the farther one that by the subsequent twisting action exercised
upon the warp threads by the twisting apparatus D, causes the coils of weft thread
to be nipped so tightly between the several weft threads 17, 21 and wires 18 as to
be brought by these in a tightly stretched condition, on leaving the tongue, against
the vertical edge of the knife 19 so as to enable this to cut the loops in two.
The knife 19, which receives a vertical reciprocating motion as will be presently
described, is arranged so as either to cut through the weft loops at the middle,
between the two sets of warp threads, or nearer to one side than the other, as may
be desired.
After the weft loops have been cut through, the wires 18 separate from the weft
threads 17, 21 the former being led over pulley while each set of the latter,
carrying the cut chenille threads between them, pass through holes in adjustable
arms 23 to the twisting mechanism D in order to be further operated thereby as
already described.
The connection of the fixed hollow axis 8 with the framing is effected by
casting 24 carried by two horizontal bearers b. On this casting 24 there are
mounted the rollers 22 with spring action in such manner that they are auto-
matically pressed against the tongue 16. They are for this purpose mounted
rotatably near the middle of arms 25 which are pivotted upon a pin 26 at one end
thereof while the other end is acted upon by a spring 27 connected to both arms.
The casting 24 also has a vertical hole 24' in which is mounted the knife carrier 28
and also the knife 19 in a rotatable manner. To the lower end of the knife
carrier 28 which passes through the casting is attached a rocking arm 30. To the
other end of this rocking arm is connected a rod 32 with a slotted connection 31,
the other end of such rod being connected in a similar manner to the rocking
arm 33. The latter rocks upon a pivot 34 on the framing and the free end thereof
is acted upon by a cam 35. This cam is fixed on a shaft 36 carried by the framing
and receives its motion by means of the cord pulley 37 on the latter which is driven
from another pulley 38 on the driving shaft A¹ by means of an endless cord 39
which is led over adjustable guide rollers 40 and 41.
During the continuous forward motion of the warp threads, wires and weft
threads, the fixed knife 19 cuts the weft threads as these are presented to it.
If however, shaped chenille is to be produced, the above named parts 19, 28, 30,
32, 33, 35, 37, 38, 40 and 41 are driven by the cord 39. In consequence hereof,
the knife carrier 28 will be turned in the casting 24 to the right or to the left
according to the cam 35.
The knife 19 carried by the knife carrier 28 between the wires 18 then effects
the cutting of the weft threads from the centre of the knife carrier 28 in circular
arcs to the right and to the left. The shape of the chenille is consequently
dependent upon the form or size of the cam 35, the cord pullies 37 and 38 and
the connecting rods 30, 32 and 33.
The forward feed of the warp thread 17 is effected in such a manner that in
passing each from a bobbin 42 at the rear end of the machine they are led each by
a roller 43 into the hollow axis 8. The warp threads 21 pass each from a
bobbin 44, and passing over a guide roller 45 which is adjustable relatively to the
casting 24, they pass to the above named rollers 22.
The speed of the bobbins 42 as also of those 44 is regulated by weights 42¹
and 44' which exert a tension upon a cord 42° and 44° passing into a groove of the
bobbin. The warp threads are thus wound off to an extent corresponding to the
pull exerted by the twisting apparatus.
The wires 18 on the other hand are fed forward by toothed wheel transmission
the first wheel of which 46 is fixed on the driving shaft A'. By means of the
intermediate wheels 47 to 52 the rotary motion of the driving shaft A¹ is
transmitted to a shaft 53 carried in bearings at the rear of the upper end of the
chenille machine. On this shaft 53 is a pulley 54 having five grooves. In the
same plan with and at the same height as the pulley 54 there is a second pulley q
on the side of the rollers 20 opposite to 54, and which has only four grooves.

page_text: Round these pullies 54 and the wires 18 are made to travel several times, the
upper ends situated between the rollers being made to pass through the hollow
axis 8 the tongue 16, as also the rollers 20 and 22, the wire being made to pass
from a bobbin 56 at the rear end of the machine into the first groove of the
pulley 54 while the part of the wire running off the fifth groove of this pulley is
wound up on a bobbin 57 arranged by the side of 56, but which is driven from the
shaft 53 by means of pullies 58 and 59 and an endless cord 60.
I
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is -
1. A winding-on apparatus for chenille machines wherein the chenille passes in
an axial direction into the hollow of a spindle d and issues from the same in a radial
direction over a support on an arm g of this spindle d and on to the periphery of a
bobbin h rotatable on the spindle, such bobbin being ordinarily prevented from
rotating by means of a strained cord i passing round the same, but being made to
partake of the motion of the spindle as soon as the chenille is subject to a strain
that can
overcome the frictional resistance of the cord whereby the use of a
carriage running on a long line of rails is dispensed with and the degree of tension
of the chenille is capable of being regulated by regulating the frictional resistance
of the said cord on a pulley fixed to the bobbin 4, substantially as described.
2. In winding-on apparatus such as is referred to in the preceding claim, the use
for the purpose of imparting increased twist to the chenille, and providing for a
subsequent untwisting thereof for preventing kinking, of a device for twisting the
chenille wherein the latter is made to enter in an axial direction into the one end
of a tubular spindle d' which revolves faster than the spindle d of the unwinding
apparatus, and from the other end of which the chenille passes in a radial direction,
first over a support on an arm g' fixed to the tubular spindle, and over a roller o on
the said spindle, to the second support from which it passes radially into and axially
out of the tubular spindle again, to the winding on device, the roller o being formed
with a roughened surface for preventing the slipping of the chenille thereon so that
the roller is ordinarily carried round by the tubular spindle at a speed less than
that of the latter to the extent of the forward feed of the chenille but revolves at
the same speed as the spindle whenever the tension of the chenille is sufficient to
overcome the frictional resistance of a strained cord i passing round the roller,
substantially as described.
