PROVISIONAL SPECIFICATION.
Improvements in Yarn or Thread Winding Machines.
We, BENJAMIN HOLT and FRANK ASHWORTH HOLT, both of Thomas Holt
Limited, of Atlas Iron Works, Molesworth Street, Rochdale, in the County of
Lancaster, Machine Makers and Ironfounders do hereby declare the nature of this
invention to be as follows:-
Our invention relates particularly to the quick reciprocating traverse motion
employed in winding machines for cross winding yarn on to cylindrical spools,
cheeses, or bobbins without flanges, and our chief object is to obtain a silent
traverse motion.
In carrying our invention into effect we employ the usual traverse rail which
carries the thread guides, and we give this rail a quick reciprocating traverse
motion in the following manner :-
Near one end of the rail we prefer to cover two of its sides with a short strip of
leather or other suitable material; this portion of the rail rests between two pairs
of special rollers.
These rollers are larger in diameter on one half of their circumference than upon
the other half, and they are set upon their axes so that when one pair of the
opposite rollers is coming out of contact with the leather on the rail, the other pair
is coming into contact with the leather, and as all four rollers are geared together
it follows that the two rollers on each side of the rail run in opposite directions to
one another, while each pair of the rollers on opposite sides of the rail also run in
opposite directions.
One roller of the set is driven in any convenient manner and transmits motion to
the others as described; as the larger diameter of each pair of opposite rollers acts
upon the leather the rail is traversed in one direction, and as soon as this pair
moves clear of the leather the other pair of rollers comes into contact with the
leather, and carries the rail in the opposite direction, and thus we obtain a silent
and reliable reciprocating traverse motion for the rail with the thread guides.
In order to ensure one pair of rollers having come out of contact before the other
pair comes into contact with the leather on the rail, we propose to make the larger
diameter of each roller a trifle less than one half its circumference, and we employ
suitable stop pieces or buffers for the rail, so that the momentum of the rail will
bring the rubber or other buffer piece against the stop at each traverse after the
rollers have come out of contact with the rail, and give to it a start in the opposite
direction so that the other rollers take hold of the rail and traverse it in the other
direction.
In order to put more or less friction or weight on to the cheeses or crossed
bobbins when being wound we propose to employ a split bearing for each cradle on
the cradle supporting shaft, or studs, and we employ a nipping screw or equivalent
to tighten these bearings and so vary the tension on the cradle shaft, and pressure
on the cheeses, or bobbins.

We, BENJAMIN HOLT and FRANK ASHWORTH HOLT, both of Thomas Holt
Limited, of Atlas Iron Works, Molesworth Street, Rochdale, in the County of
Lancaster, Machine Makers and Ironfounders, 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:—
Our invention relates particularly to the quick reciprocating traverse motion
employed in winding machines for cross winding yarn on to cylindrical spools,
cheeses, or bobbins without flanges and our chief object is to obtain a silent
traverse motion.
In carrying our invention into effect we employ the usual traverse rail which
carries the thread guides, and we give this rail a quick reciprocating traverse
motion in the following manner :-
Near one end of the rail we prefer to cover two of its sides with a short strip of
leather or other suitable material; this portion of the rail rests between two pairs
of special rollers.
These rollers are larger in diameter on one half of their circumference than upon
the other half and they are set upon their axes so that when one pair of the opposite
rollers is coming out of contact with the leather on the rail the other pair is coming
into contact with the leather and as all four rollers are geared together it follows
that the two rollers on each side of the rail run in opposite directions to one
another while each pair of the rollers on opposite sides of the rail also run in
opposite directions.
And in order that our invention may be fully understood and readily carried into
effect we will describe the accompanying sheet of drawings reference being had to
the figures and letters marked thereon.
Figs. 1 and 2 are side elevation and plan respectively of the end portion of a
thread winding machine to which our improved quick reciprocating traverse motion
is applied and
Fig. 3 is a detail of part of the traverse motion.
Similar letters refer to similar parts throughout the several views.
a is the frame of the machine, b the driving shaft on which are mounted a pair of
fast and loose pulleys c c and a grooved pulley d which by means of a band or
cord e and the grooved pulleys f' gives motion to one of the two shafts the other
shaft being driven by a band from the first shaft. The drums g for giving motion
to the paper tubes or bobbins are secured on the shafts and the said tubes or
bobbins are carried in swing cradles h pivoted on stationary rods or bars i.
Supported in suitable brackets on the frame a are two traverse rails ; which carry
thread guides and receive a quick reciprocating traverse motion by means of two
pairs of special rollers k k and 11 which are larger in diameter on one half of their
circumference than upon the other half; these rollers are so set upon their
axes k¹¹ and that when the larger diameters of the rollers k k are in contact
with pieces of leather or other suitable material w attached to the traverse rail j
the smaller diameter of the rollers adjoin the rail j and vice versa; rotary
motion is imparted to these rollers by means of a bevel wheel m secured upon the
driving shaft of the machine, see Fig. 1, and a bevel wheel n mounted upon the
axis of the rollers k; these four rollers kk and 11 are all geared together by four
spur pinions o which gearing gives to each pair of rollers on opposite sides of the
traverse rail, motion in the opposite direction and also drives the pair of rollers kk
in the opposite direction to the rollers 11. On each traverse rail; is a forked
bracket p, see Fig. 3, the shank of which is drilled out to slide upon a rod r carried in
a brackets secured to the frame a of the machine, on a screwed portion at each end

page_text: of this rod is a pair of locknuts t for adjusting the position of a pair of rubber or
other suitable buffer pieces u u' on the rod and in order to ensure that one pair of the
rollers k or shall come out of contact before the other pair comes in contact with
the leather on the rail we make the larger diameter of each roller a trifle less than
one half its circumference.

In front of each traverse rail j is a fixed guide rail over which the yarn or
thread from the bobbins or cops, not shown, passes through the thread guides j¹ to
a paper tube or bobbin carried by the swing cradles h above the driving drums g.
In operation the ends of yarn or thread are brought over the guide rods and
through the guides on the quick reciprocating traverse rails to the tubes or
bobbins in the cradles h; the machine is then ready to be set in motion the yarn
being wound on to the tubes in the shape of cheeses or crossed bobbins by frictional
contact with the drums g, at the same time the traverse rails are moved in the
direction of the arrow, see Fig. 2, by frictional contact with the rollers k k and as soon
as they come out of contact with the rod the momentum of the latter curries it forward
slightly until the bracket p meets the elastic buffer u which gives it a start instantly
in the opposite direction previous to the coming into action of the other pair of
rollers which nip it and carry it forward in the opposite direction until the other
buffer u stops and reverses the movement of the rod j.
When our improvements are applied to a double machine the traverse rails may
each be driven by independent pairs of rollers k k and Il or a single motion may be
employed and the traverse rods connected to move simultaneously in opposite or the
same direction.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
:―
In a yarn or thread winding machine-
1. The arrangement use and application of two or more pairs of rotating rollers,
each roller having one half of its circumference larger than the other half to form a
driving surface and all being arranged to traverse the thread guide rail to and fro
in opposite directions as and for the purposes described and as illustrated in the
accompanying drawings.
2. The combination with the rotating rollers having two diameters for traversing
the guide rail in opposite directions as herein set forth, of elastic buffers placed as
and for the purposes described and as illustrated in the accompanying drawings.
