Republic of France, Manufacturer.]
Improvements in and relating to Spinning, Doubling, Twisting,
Winding, and similar Frames.
I, HENRY HARRIS LAKE, of the firm of Haseltine, Lake, & Co., Patent Agents,
45 Southampton Buildings, in the County of Middlesex, 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 spinning, doubling, twisting, winding and similar frames,
and has for its object to keep the feed rollers or cylinders which in the frames
heretofore employed receive an oscillating movement in a fixed position. This
oscillating movement was designed to keep the fed thread constantly stretched,
notwithstanding the irregularity in the winding up resulting from the variation of
the diameters for the winding, and the perturbing action of the thread carrier guide
chariot which in its upward and downward movement alternately relaxed or
stretched the thread.
For enabling the feed cylinders to be kept in a fixed position and yet maintain a
constant tension of the thread I now act upon the speed of the winding up which
must be varied proportionately to the aforesaid causes, that is to say in proportion
to the variations of the diameters for the winding up and in proportion to the
movement of thread guide carrier chariot. But for enabling the speed of the
winding up to be acted upon in this manner it is necessary to isolate it as it were by
the use of a device which will produce directly the number of revolutions for the
winding up in the same manner as a device producing directly the number of
revolutions of the feed cylinders.
In fact up to the present time the winding up has not been effected directly in
the frame described in a former Patent No. 10,962 of 1884 and hereinafter termed
the Chapon frame; the speed of the winding up is the result of the difference
between the speed of the cone and of the spindle, that is to say N being the
number of revolutions of the cone, N¹ the number of revolutions of the
spindle, N-N will be the number of revolutions for the winding up. Now
the number of revolutions N¹ of the spindle being obtained directly by causing its
operation to start from the number of revolutions N of the cone, and the number
of fictitious revolutions N, N¹ was obtained only indirectly.
I
In lieu of producing the numbers of N and N¹ directly and by difference N-N'
may produce the number of revolutions N and N-Ni directly and by difference
the number of revolutions N', because N'-N-(N=N¹).
I thus produce in reality not only N and N but also their difference N-N'
which will as it were be isolated and constitute a speed which may be directly
increased or diminished.
For realizing this desideratum the operation N₁ of the spindles must be effected
by the subtraction of two movements N and N-N', that is to say upon the
shaft O' of the spindles must be arranged a subtraction apparatus which on the
one hand receives the speed N and on the other hand the speed N-N', and which
will transmit to the shaft the differences between these two movements.
It is the differential movement on which this subtraction apparatus
differential movement may be obtained with spur wheels or with bevel wheels, the
principle remains the same, the proportions of the gearing alone vary.
based this
Figures 1, 2 and 3 represent the movement with spur wheels such as it is applied
to the machine; the movement comprises:
(1) A wheel C provided interiorly with 60 teeth, this wheel being loose upon the
shaft O which drives the spindles.

page_text: (2) Two intermediary wheels d d with 20 teeth, carried by the differential
wheel D and gearing with the interior wheel C and also with the pinion f keyed
upon the shaft O' of the spindles.
(3) The differential wheel D with 75 teeth, likewise loose upon the shaft O' of
the spindles.
(4) The pinion with 20 teeth, keyed upon the shaft O' of the spindles.
According to the number of teeth the interior wheel communicates three times
its own speed to the keyed pinion f, whilst the differential wheel communicates four
times its own speed to this pinion. The direction of rotation of the interior and
differential wheels being the same the speeds which they transmit to the pinion f
that is to say to the shaft O' of the spindles will be in the opposite direction and
therefore they will be deducted.
One of the parts of the differential movement must communicate to the shaft O'
of the spindles a speed equal to that of the shaft of the cones.
For this purpose
I arrange upon the nave or socket of the interior wheel a wheel b gearing with
the pinion a fixed upon the shaft O of the cones, the proportion being; the
interior wheel therefore moves at of the speed of the shaft of the cones, but as
it transmits three times its own speed the pinion will receive from the interior
wheel a speed which is equal to that of the shaft of the cones.
I therefore say that the wheel C receives from the shaft of the cones a speed
equal to of that of this shaft; in like manner the wheel D, the operation of which
is effected from the shaft A (Figure 4) through intermediate wheels of any desired
proportions, must receive a speed equal to of that which it must transmit to the
pinion f. This operating device is constructed in such a manner that the length
wound up is equal to the length fed. It is therefore in my power, according to
what has been stated, to produce directly the speed for the winding up N-N¹.
The axis A (Figure 4) serves as a starting point also for the feed mechanism and
as the lengths fed and wound up must always be equal irrespective of the tension to
be produced, it will be sufficient for varying this tension to vary the speed of the
shaft A.
In this manner the application of the differential movement, besides the principal
object aimed at, which is to isolate the speed for the winding up, has also the
advantage of combining this speed with that of the feed. The isolation of the
number of revolutions for the winding up thus obtained will now enable the variation
of this number of revolutions to be obtained, in view of the inequality of the
diameters for the winding up. In fact the winding up in the Chapon frame which
produces bobbins cops and cocoons is effected not upon a cylindrical part but upon
a cone; in proportion to the upward and downward movements of the thread-guide
the thread is wound up upon an increasing or diminishing diameter, the number of
revolutions for the winding up remaining constant, the lengths wound up increase
therefore from the base to the top of the cone and decrease from the top to the
base which in consequence of the regular feed of the thread during the same time
gives rise alternately to too much or too little tension as above stated.
For regulating this tension the Chapon frame hitherto used provided for an
oscillating movement of the feed cylinders which absorbed the excess of the fed
thread or restituted it at the proper moment. To obviate this oscillating move-
ment of the cylinders I vary the number of revolutions for the winding up in each
movement of the chariot in inverse ratio to the diameters of the bobbin, that is to
say d being the variable diameter for the winding up I vary the number of
revolutions N-N1 so that d n (N-N') shall always be constant and equal to the
length of the fed thread.
The variation of N-N¹ is obtained by the intervention in the mechanism for
producing this movement of a pair of eccentric wheels E and E' (Figure 4). I can
also obtain this variation by other devices, such as transmission by belts adapted
to be displaced upon two cones, or friction shifting between two discs so as to
approach alternately the centres of one or the other, but I use here eccentric wheels
as providing for a more accurate movement.

page_text: In its to and fro movement the thread guide carrier chariot alternately approaches
and recedes from the feed cylinders, it therefore also relaxes or stretches the thread
alternately too much. During the upward movement this length equals the average
feed minus a length equal to the movement of the chariot; during the downward
movement it equals the average feed plus a length equal to the movement of the
chariot.
To obviate this inconvenience and obtain regular tension of the thread it is
therefore necessary to wind up during the upward movement of the chariot a length
of thread equal to the normal length plus the movement of the chariot, and during
the downward movement a length equal to the normal length minus the movement
of the chariot.
For this purpose I combine also with the differential movement a special
operating mechanism in the following manner:
Instead of actuating the differential wheel D (Figure 2) directly by the
mechanism receiving its motion from the shaft A (Figure 4) I actuate directly a
wheel G with the same number of teeth which is placed by the side of it upon
the same axis and like it is loose upon the same support.
These two wheels engage with the same pinion H which for this purpose has a
width equal to that of the two wheels. The pinion H is loose upon an axis carried
by the levers K and K¹ articulated upon the shaft O' of the spindles so as to be
able to move around the wheels D and G without coming out of engagement with
them.
Supposing the pinion H to be at rest, the wheel G communicates through this
pinion to the wheel D a speed equal in amount to and in the same direction as that
which it receives itself from the direct operation for the winding up, but by giving
to the levers K and K¹ which carry the pinion H a rotary movement around the
shaft of the spindles this pinion will turn upon its axis not only under the action of
the wheel G but also under the action of the movement of the levers K and K
which according to its direction will be in addition to or subtraction from the
principal movement. Accordingly by giving to these levers a movement sometimes
in one direction and sometimes in the other, the wheel D will be moved at a speed
equal to the speed for the winding up plus or minus a certain quantity.
The oscillating movement of the pinion H is obtained from the shaft M actuating
the chariot and carrying a crank m the pin of which moves in a slot of the lever P.
It is constructed in such a manner that when the chariot moves upwards the action
of the crank will be in addition to the movement for the winding up, and will be
in subtraction during the downward movement. The extent of the oscillating
movement may be regulated by displacing the crank pin in a slot so as to obtain
exactly a wound up length either extra or less and equal to the movement of the
chariot.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, as communicated to me
by my foreign correspondent, I declare that what I claim is,
The application of the apparatus herein before described to the Chapon frame,
and also to any spinning, doubling, twisting, winding and similar frames to which
the said apparatus may be adapted for the same purposes.
