Hitherto in the printing of yarus and threads it has been customary in "filling"
or winding the yarn or thread upon the printing drums in order to spread the yarn
equally over the surface of the drum to make use of a travelling guide or guides.
The said guide or guides has or have been attached to a bar to which lateral
motion was given by means of a worm suitably operated by a train of wheels.
The closeness with which the yarn has been wrapped upon the drum has been
determined by the speed at which the bar and guides. have been traversed

has proved to be fairly satisfactory when the whole of the yarn to be wound
upon the drum has been of the same thickness but, has been unsatisfactory when a
drum has been filled with yarns of different thicknesses, as when the traverse motion
has been adjusted for the thicker yarn, the thinner yarn has been too sparsely spread
on the drum and vice versa.
According to our invention instead of making use of a traversing bar to which
is or are attached the guide or guides, we use a revolving bar, the speed of which
is regulated and can be varied as required by change wheels or other suitable
means. Upon the said revolving bar we mount in such a manner as to revolve
with it, what we term sections; according to one arrangement the length of each
of these sections is determined by the space which the yarn controlled by the said
section should occupy on the drum. The space which should be occupied on the
drum is determined according to the thickness of the yarn.
Each of these sections is screw-threaded the number of threads on each section
being the same irrespective of its length.
Whilst the screw-thread on the section may itself be used as a guide for the
yarn we find it advantageous to provide each section with a guide or guides
actuated by the screw thread on the section, and by this means effecting the suitable
distribution of yarn as it is wound upon the drum. According to another arrange-
ment we construct each section of equal length and vary the number of screw-

possible at the same time to distribute the yarn with different sections upon the
surface of the drum as close or as open as may be required with one speed of the
revolving bar, we find it advantageous, in order to prevent the unnecessary multi-
plication of sections to be able to vary the speed of the said bar.

We, JOHN CROSSLEY & SONS, LIMITED, of Dean Clough Mills, Halifax, in the
County of York, Carpet Manufacturers, and URIAH BAIRSTOW, of Dean Clough
Mills, aforesaid, Commercial Clerk, 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 to improvements in machinery used for colour printing
on yarn, threads or the like of worsted and other materials whereby yarns or
threads of different thicknesses can be simultaneously filled or wound on the
printing drum and guided thereon by traversing guides at speeds proportionate
to the thicknesses of the yarns so as to obtain a regular or even distribution on
the drum.
Hitherto in the printing of yarns and threads it has been customary in "filling"
or winding the yarn or thread upon the printing drums in order to spread the yarn
equally over the surface of the drum to make use of a travelling guide or guides.
The said guide or guides has or have been attached to a bar to which lateral
motion was given by means of a worm suitably operated by a train of wheels.
The closeness with which the yarn has been wrapped upon the drum has been
determined by the speed at which the bar and guides have been traversed
and the train of wheels has been so arranged that the speed could
be varied to any required extent by means of change wheels. This method
has proved to be fairly satisfactory when the whole of the yarn to be wound
upon the drum has been of the same thickness but has been unsatisfactory when a
drum has been filled with yarns of different thicknesses, as when the traverse motion
has been adjusted for the thicker yarn, the thinner yarn has been too sparsely spread
on the drum and vice versa.
According to our invention instead of making use of a traversing bar to which
is or are attached the guide or guides, we use a revolving bar, the speed of which
is regulated and can be varied as required by change wheels or other suitable
means. Upon the said revolving bar we mount in such a manner as to revolve
with it, what we term sections; according to one arrangement the length of each
of these sections is determined by the space which the yarn controlled by the said
section should occupy on the drum. The space which should be occupied on the
drum is determined according to the thickness of the yarn.
Each of these sections is screw-threaded the number of threads on each section
being the same irrespective of its length.
Whilst the screw-thread on the section may itself be used as a guide for the
yarn we find it advantageous to provide each section, with a guide or guides
actuated by the screw thread on the section, and by this means effect the suitable
distribution of yarn as it is wound upon the drum. According to another arrange-
ment we construct each section of equal length and vary the number of screw-
threads throughout the length of each section. Whilst we are aware that it is
possible at the same time to distribute the yarn with different sections upon the
surface of the drum as close or as open as may be required with one speed of the
revolving bar, we find it advantageous, in order to prevent the unnecessary multi-
plication of sections to be able to vary the speed of the said bar.
To enable our invention to be fully understood we will describe how the same
can be carried into practice by reference to the accompanying drawings, in
which:-
Figure 1 is an elevation of machinery for printing yarns, threads, and the

different lengths;
Figure 2 is a section on the line 2-2 Figure 1:
Figure 3 is a view similar to Figure 1 with the framing and gearing omitted
but shewing the sections of equal lengths.
Figures 4 and 5 are respectively a front elevation and a side elevation of one
form of yarn guide drawn to a larger scale:

A is the usual revolving printing drum on to which the yarn is to be wound.
a is our revolving bar mounted in bearings b, b and carrying at one end a gear
wheel c adapted to be driven from a gear wheel d on the driving
shaft e through the medium of change wheels f, g. By employing
different sizes of change wheels, the speed of the revolving bar
can be varied relatively with the speed of the drum A so as to lay the threads
closer together or farther apart on the drum as desired. h, h¹, 12, 1³ are the
screw-threaded sections mounted upon the bar a so as to revolve with it by
suitable means such for example as by means of a key i engaging with a key-
way in the bar a, as shewn clearly in Figure 2. The several sections are held
in position upon the revolving bar a by collars j, j fixed by screws j¹, j. k, k are
the guides for the yarn, a pair of such guides being arranged in conjunction with each
of the sections h, h¹, 12, h³, the said guides being in the form of wire loops or
eyes. Each pair of guides is mounted upon a base 7 adjustably attached by a
set screw m to a screw-threaded boss or nut n engaging with the screw thread
of one of the sections on the bar a. Instead of a pair of guides one only or more
than two may be used. o is a bar arranged in lugs o¹ on the nuts n and serving
to keep the yarn threads clear of the said nuts, the said bar being secured to
one of the lugs by the screw o² but sliding in the others.
The sections h, h', h2, h3 are formed with screw threads of different pitch
according to the thickness of yarn they guide to the drum. For instance the screw
thread on the section h serves to operate the guides for the thinnest yarn while
that of the section h³ serves to operate the guides for the thickest yarn. As the
same number of convolutions of each kind of yarn will be wound upon the drum
it will be seen that each kind will cover a greater or less width of the drum's
surface than the others. For this purpose the sections (as shewn in Figure 1)
are made of different lengths, each pair of guides in connection with each section
serving to guide yarn onto a part of the drum corresponding in width with the
length of its section. In Figure 3 the sections are shewn as of equal length, but
in this case, however, only a part of each section is utilized for covering a corre-
sponding width of the drum with yarn.
Instead of the yarn being traversed by the travelling guides k, k, k, k it may be
traversed and guided by engaging with the screw thread of each section as will
be obvious.
Instead of the yarn guides described, we sometimes employ single guides of
the kind illustrated in Figures 4 and 5 each of which is provided with an eye k
for the passage of the yarn and a spring body adapted to clip one of the
sections h, h1, h2, h3 a tongue 21 being provided designed to engage with the
screw threads of the sections.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is:
1. In machinery for printing yarn, threads or the like the combination with
the printing drum of means whereby yarns of various thicknesses are simultaneously
filled or wound on the drum and guided thereon by traversing guides at speeds
proportionate to the thicknesses of the yarns for the purpose, described.
2. In machinery for printing yarn or the like in which the yarn is filled or wound
upon a printing drum, the combination with the said drum of revolving screw-

page_text: threaded sections whereby yarns of different thicknesses are simultaneously filled
or wound on the drum and guided thereon at speeds proportionate to their thick-
nesses as described.
3. In machinery for printing yarn or the like in which the yarn is filled or
wound upon a printing drum, the combination with the said drum of a revolving
bar carrying detachable screw-threaded sections having screw-threaded bosses
or nuts each carrying a guide or guides for the passage of the yarn and
whereby the yarns are guided at speeds proportionate to their thicknesses sub-
stantially as described.
4. In machinery for printing yarn or the like in which the yarn is filled or
wound upon a printing drum, the combination with the said drum of a revolving
bar carrying detachable screw-threaded sections having screw-threaded bosses
or nuts each carrying a guide or guides for the passage of the yarn and
of means whereby the speed of the bar can be varied relatively with that of the
drum, substantially as described.
5. In machinery for printing yarns of the kind described in the preceding claiming
clauses the employment of a yarn guide, substantially as described and illustrated
in Figures 4 and 5 of the accompanying drawings.
6. The improved mechanism for printing yarns, threads and the like, arranged
and operating substantially as described and illustrated in Figures 1 and 2 and
in Figure 3, respectively of the accompanying drawings.
