Lancaster Mechanical Engineer do hereby declare the nature of this invention to
be as follows:-
:-
This Invention relates to improvements in yarn winding machinery and more
particularly to the method of guiding the yarn in cross winding frames, and it has
for its object to prevent the shocks and vibrations which ordinarily arise from
sudden reversals of motion in the thread guiding apparatus.
These Improvements consist in an adaptation, combination or arrangement of the
parts hereinafter specified for the purpose of substituting a gradual reversal for the
sudden reversal of the traversing motion of the thread guide.
The thread guide is made very light and attached to its rod in such a manner
that its motion may be governed by that of the thread guide rod and by means of a
spring or springs and controlling points or stops, or by the motion of a parallel rod
or its equivalent in conjunction with the motion of the thread guide rod.
Assuming that the thread guide is a light vertical rod having the pig tail or
guiding point at its upper end and that it is pivotted to the thread guide rod at one
fourth its length from the bottom, it follows that the thread guide constitutes a
lever having the ratio 3: 1. If the thread guide is kept in a vertical position by
means of springs attached to the thread guide rod the motion of every part of the
thread guide will correspond with that of the thread guide rod. But if the lower
end of the thread guide is prevented from moving by fixed or adjustable points or
stops, the power of the spring is overcome and the thread guide assumes an inclined
position. If the lower end of the thread guide is prevented from moving the speed
of the guiding point to that of the thread guide bar will be as 3: 1 that being the
ratio of the lever.
It follows that by adopting such an arrangement as that hereinbefore assumed
the speed of the guiding point may be varied to any desired extent by varying the
proportions or ratio of the lever or on the contrary, if the guiding point is moved
exactly as required for correct winding, the speed of the thread guide rod may be
reduced to any desired amount by varying to the required extent the ratio of the
lever.

page_text: Taking the ratio for the lever already given, 3: 1, the speed of the thread guide
rod may be reduced to one fourth so long as movement of the lower end of the
lever is prevented but otherwise the motion of the guiding point will be equal to
that of the rod. Hence the fixed or adjustable points coming in contact with the
lever are adjusted to give the required acceleration or retardation at the desired
points so that the bulk of the thread guide apparatus reverses its direction at a
reduced speed and the sudden reversal is performed by the light lever and the
machine may be run at a higher speed.
This arrangement may require a modified form of heart wheel or cam.
The springs hereinbefore referred to may be dispensed with in which case the
lower ends of the thread guides are connected to a second rod parallel with the
thread guide rod. This second rod may be driven by a heart wheel cam or by
other suitable means so that its motion relatively to the motion of the thread guide
rod produces motions in the guiding point corresponding to those herein before
described as being obtained by the use of springs and stops.
Various modifications and combinations of the apparatus may be employed or
adopted for the same purpose. Thus, the thread guide may be carried upon a
block or ring sliding in or upon a fixed rod. The block or ring may be driven by
an oscillating three pronged fork the central tine of which is in effect shorter than
the outer ones. The short tine moves the block or ring from and to near each end
of the traverse at either of which points the block or ring has compressed a
spring and is liberated from contact with the middle tine of the fork. The spring
then pushes the thread guide in the opposite direction until it is arrested by an
outer tine of the fork the motion of which has now been reversed. The central
tine now engages with the ring or block and carries it to the other end of the
traverse when the operation of reversal is repeated.

page_text: I, WILLIAM EDWIN HEYS of 70 Market Street Manchester in the County of
Lancaster Mechanical 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:―
This Invention relates to yarn winding machinery and more particularly to
machinery for winding yarn without the use of flanged or similar reels or bobbins
as described in the Specification to Letters Patent granted to Ferdinand Rosskothen
No 1051 dated 9th January A.D. 1884 and it has for its object to prevent the
shocks and vibrations which ordinarily arise from sudden reversals of motion in
the thread guiding motion or apparatus by substituting a gradual reversal of the
traversing motion of the thread guide.
And in order that this Invention may be more readily understood and carried
into practical effect I have hereunto appended a sheet of Drawings having the
various Figures thereon marked with letters to denote the various parts, similar
parts in different Figures being marked with similar letters and reference being
hereinafter had thereto.
Figs. 1. 2 and 3 are diagrams of different modifications of these Improvements
for obtaining the motion of the thread guide.
Upon the thread guide rod or its equivalent S there is mounted a light lever by
means of the pin pivot or fulcrum b to the upper end of which is attached the pig
tail or thread guide c. In its position of rest this light lever may be kept vertical
by means of a spring attached to its lower end the spring itself being carried by
the thread guide rod as in Fig. 1. Since the lever moves with the rod S the motion
of the point c will ordinarily be equal to the motion of S, but if the lower end of
the lever is prevented from partaking of the motion of S by contact with a fixed
point such as m the action of the spring is overcome and the lever assumes the
inclined position indicated in the full line a b c Fig. 1. So long as the point a is
fixed or prevented from following the motion of the rod S its speed as compared
with that of the rod is equal to
a-c
From this it is obvious that the speed of the point c may be varied relatively to
the speed of S by varying the proportions ab and bc of the lever or on the
contrary if the point c is moved precisely as required for correct winding the speed
of the rod S may be reduced to any reasonable amount by choosing suitable propor-
tions for the lever. If for example a b: a c is made equal to 1: 4 the speed of the
rod S may be reduced to one fourth of the speed required for c so long as the point a
is prevented by the fixed or adjustable stop m from following the motion of S.
When the motion of the rod is reversed the action of the spring restores the lever
to the vertical position and the point a being no longer in contact with or controlled
by m the speed of c becomes equal to that of S until it is again accelerated by
contact of the point à with the fixed point m 1 at the opposite end of the stroke.

page_text: The relative motions of the points or parts S and c are indicated in the graphic
diagram Fig. 4 where the speed of the thread guide c is indicated in the dotted
lines and that of the thread guide rod in full lines. The vertical distances
correspond to the motion of the thread guide and the horizontal correspond to
time, one complete cycle of motions being represented. The ratios chosen for the
parts a band a c of the lever equal 1:4. It will be seen that, between the
points m and m 1 the speeds of the rod S and of the thread guide C are equal, but
that the speed of the point C is four times greater than that of the rod S as soon
as and during the period that the lower end of the lever is in contact with the
stationary point m or m 1.
This Invention consists in a combination or arrangement of various parts or
details for the purpose of effecting a quick reversal of the thread guide or
equivalent leading point c with a reduction in the amount of vibration at present
experienced. By this combination or arrangement the heavier portions of the
thread guiding motion or apparatus may be reversed at a reduced speed while the
requisite sudden reversal is effected by the light lever. The vibrations which are
a great defect in existing apparatus of the like character are thus greatly diminished
and the thread winding machine may be run at a high speed with safety.
Fig. 5 represents a heart wheel or cam suitable for actuating the thread guide
rod S.
If springs are employed as illustrated by the diagram Fig. 1 the heart wheel or
cam is shaped as shown by the full line Fig. 5. If no additional motion is used
for the point c the cam or heart wheel must be shaped as indicated by the dotted
lines Fig. 5.
In Figs. 2 and 3. is represented an arrangement for driving the thread guide
positively without the use of a spring. The light lever to which the thread guide c
is attached is connected at its lower end to a rod d which is driven by a heart
wheel, cam or other. suitable means in such a manner that the motion of c resulting
from the respective motions of S and d is precisely that required for correct
winding. In these Figures the rod S is represented as driven or actuated by a
crank pin and slot and the rod d by a suitable heart wheel but either or both the
rods may be driven by other suitable means or one of the rods may be fixed
provided that the resultant motion in c corresponds with the dotted line in the
graphic diagram Fig. 4.
In Fig. 6 the thread guide c is represented as attached to a sliding bracket or
piece e which is capable of motion within a slot in the stationary bar f. The
bracket e is moved or actuated by the three tined fork h. The middle arm or tine 2
of the fork bears against the pin i on the bracket e and moves it to and fro in the
slot but at the end of the traverse the pin slips over the arm or tine 2 and is
pushed to the opposite side by the spring g until it comes into contact with the
arm i.
At the same time the movement of the fork is reversed and the arm or
tine 2 again drives the pin i but from the opposite side. Figs. 7 and 8 shew a
winding frame having horizontal spindles and provided with a combined thread
guiding motion constructed and arranged according to these Improvements.
The construction and arrangement of the apparatus for producing the combined
or resultant motion in c which is the object of this Invention may be varied in
many ways other than those shown on the Drawings and hereinbefore described
and I do not limit myself therefore to the precise details and combinations set
forth.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed I declare that what
I claim is:
