between the ranks of combs if more than one rank is used. The yarns are led through
the clearing comb or combs and over the said revolving or oscillating bar or part

yarns as they pass through the combs and thus subjecting the entire circumference of

Improvements in Means for Facilitating the Clearing and Cleansing
of Yarns and Textile Fibres in Winding and other Machinery
used in the Manufacture and Preparation of Yarns and Fibres.
I HENRY TETLOW of Varley Street, Oldham Road, Manchester, in the County of
Lancaster, Heald and Wire Manufacturer, do bereby 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 and accompanying
drawings:-
My said Invention relates to improved means for facilitating the clearing and
cleansing of yarns and textile fibres from inequalities and impurities during the process
of winding or otherwise during the treatment or manufacture of such yarns and
fibres. In the specification of an invention for which I have obtained Her Majesty's
Royal Letters Patent No. 3212 of the year 1886, 1 described certain forms of clearers
consisting of fixed combs made from flat wire similar to the dents of loom reeds, the
said flat wire being finished on the edges or sides so as to present a square edge to
the yarn passing through the clearer. The said dents were set to any desired pitch
corresponding in fineness to the yarn upon which the clearer was intended to act.
In using the said clearing combs, I have found that the impurities and portions of
fibre and fluff removed from the yarns are sometimes apt to collect at the front of the
combs and either choke and break the yarn or form knots thereon. To obviate this
defect I keep shifting the position of the yarn between the dents, or the combs them-
selves may be moved so that the yarns do not pass through the combs constantly at
the same point or level. By preference I move the yarns up and down in the combs
by means of a revolving or oscillating flat or oval or cam shaped or square or
polygonal bar, shaft or part which is situated behind or in front of the combs, or
between the ranks of combs if more than one rank is used. The yarns are led
through the clearing comb or combs and over the said revolving or oscillating bar
or part which causes the yarns to rise and fall as they pass through the comb or
combs. This rising and falling motion has probably the effect of giving a rolling
movement to the yarns as they pass through the combs and thus subjecting the entire
circumference of each yarn end to the clearing and polishing effect of the dents, but
in any case the actual results show a manifest and important advance in the quality,
appearance and finish of the yarns. It will be evident that instead of having a
revolving or oscillating bar or part to move the yarns up and down during their
passage through the combs the combs themselves might be raised and lowered the
ultimate effect being the same. In some instance I might attach a series of combs
to a revolving shaft or axis, the said revolving arrangement of combs acting upon the
yarns in the manner aforesaid. The revolving or oscillating or reciprocating or
sliding bars or parts, for moving the yarns up and down or the rising and falling or
revolving combs are operated from any suitable part of the mechanism of the winding
frame or apparatus to which my invention is applied.
In order that my 'said invention may be properly understood I will now proceed to
describe the same more particularly and with reference to the annexed sheet of
drawings which clearly illustrates several modes of carrying my invention into
practical effect.
Fig. 1 of the said drawings is a view of the chief working parts of one side of a
winding frame as they would appear in a cross sectional view of such a frame. The
ends of the frame and those parts of the mechanism which are not essential to the
illustration of my invention are left out of the drawing.
Fig. 2 is an enlarged sectional view of the chief modification of my improved
means for causing the yarn to rise and fall as it passes through the clearing and
cleansing combs.
Fig. 3 is a front elevation of part of Fig. 2 the front comb being removed to show
the vibrating bar more clearly.

page_text: Fig. 4 is a portion of a plan view of Fig. 2.
Fig. 5 is a separate view of a portion of a clearing comb.
Figs. 6. 7. 8. and 9 are sectional views of modifications of my invention.
Referring in the first instance to Figs. 1 to 5 of the drawings the dotted line
marked a represents in all cases the yarn or yarns which is or are being operated
upon. The yarns a in Fig. 1 are led from the cops through the eyes c and through
the cleansing brushes d to the front rank comb e thence over the interposed vibrating
bar to the second rank comb y and thence to the eyes h of the stop motion after
which the yarns pass over the top rollers i and are wound upon the bobbins j which
lie in frictional contact with and are driven by the revolving pullies k on the central
driving shaft of the frame. The dotted line e indicates the centre of the frame, the
parts just described being repeated on the other or left hand side of the frame. The
combs e and and the bearings of the vibrating bar fare carried on the breast heam
or stay m which is a part common in the construction of such a frame as I have
illustrated The combs e and g are made from flat wire or dents in accordance with
the specification of my Patent No. 321286 already referred to, an example of a portion
of a comb in its setting w being given at Fig. 5. The subjects of my present inven-
tion are more particularly the various means for obtaining a change in the position
of the yarns or of the combs relatively to each other while the cleaning or cleansing
operations are being carried on. The vibrating bar f illustrated in Figs. 1 to 4 is
one of the methods I employ and the method which after practical trial I consider to
be the most simple and useful. The said bar fis or may be of the sectional form
more particularly shown in the enlarged view Fig. 2 and is of any suitable length
corresponding to the frame. The bar is reduced at the ends so as to form journal
necks which are carried in bearings n which appear in Figs. 1 and 2. One end of
the said neck f is extended as shown in Fig. 3 so as to carry a lever o. The said lever
is bored or slotted to take a pin or stud p and a connecting rod q extends from the stud p
to a similar stud on a collar on the end of the driving shaft as clearly shown in the
detached view Fig. 1 of the drawings. As the shaft revolves the lever o is vibrated to
and fro and consequently the bar fis similarly vibrated. The amount of vibration may
be regulated by adjusting the stud p in the slot in the lever o. In Figs. 1, 2, and 3
the bar is shown upright and the amount of vibration is indicated by the dotted
lines shown on both sides. The amount of rise and fall thus given to the yarn is
indicated by the distance appearing between the yarn a and under dotted line y
Fig. 2. The bar f may be either smooth on the top edge or it may be notched or
serrated as in Figs. 3 and 4. When the invention is in operation the yarns are led up
to the combs and passing through the same and over the top of the vibrating bar f
are moved up and down in a vertical plane so that the position of the yarn between
the dents of the combs is continually being changed the liability of the yarns to stick
and choke between the dents of the combs being considerably lessened. Another
advantage arising from my invention is that by the rising and falling of the yarn a
rolling contact with the sides or edges of the dents is set up and the entire cir-
cumference of the yarn is acted upon, the yarn being thus more completely cleansed
polished and finished than heretofore whereby the quality, appearance and value of
the yarn is considerably enhanced. It will be evident that the bar instead of
vibrating as described might be made to revolve, or the bar might be made double,
as at f Fig. 6, and revolved, the journal of the bar being in such a case fitted with
a pulley instead of the lever o the said pulley being driven by a cord or belt from a
similar pulley on the driving shaft 1. Instead of a bar of the indicated section, a
square or triangular or other shaped bar might be used. By another modification
which is illustrated at Fig. 7 I carry the bar f³ in slides and so raise the bar
up and down perpendicularly by means of a connecting rod from a suitable
moving part of the frame, or the bar f³ may be reciprocated in any other suitable
manner. When I use the rising and falling bar f³ I do so in conjunction with a
double rank of combs made in accordance with my aforesaid previous patents.
Instead of causing the bar f to rise and fall it is evident that the combs e, g might
be carried in slides or levers and be moved up and down instead of or in combination

page_text: with the vibrating or reciprocating bar f. In Fig. & I have shown the combs e. and g
as being mounted on a frame z and arranged to vibrate on a pivot u. In this case, the
bar fis dispensed. with and the yarn a is acted upon by the combs e. g as they vibrate
upon the pivot. u. The pivot u and the combs might be operated by the arrangement
shown at Fig. 1. In Fig. 9 I show another modification in the mode of actuating
the combs. In this case I mount the combs e. e', g. g¹ upon a central revolving
carrier which is caused to revolve from any suitable moving part of the frame,
whereby the combs are caused to act upon the yarns a with the results described with
reference to the foregoing Figs. It will be evident to mechanicians that the fore-
going mode for giving motion to the lifting and lowering bars or parts and to the
combs are by no means exhaustive, and I am well aware that further modifications in
such methods might easily be devised. For example the combs and carriers instead
of being moved up and down, or vibrated on a pivot, or revolved as described and
shown might be moved in a circular path by an excentric, crank or other means.
Instead of using a double rank of combs as in the drawings I might use a greater
number of ranks than two. My invention is applicable to all machines used in
the manufacture preparation or treatment of yarns in which it is desirable or
customary to cleanse or clear the yarns from inequalities and imperfections as
aforesaid.
Having now particularly described and ascertained the nature of my said Inven-
tion and in what manner the same is to be performed I declare that what 1
claim is :-
(1) In yarn cleansing and clearing apparatus of the indicated description the
employment of a vibrating or reciprocating bar or part either plain or serrated
on its top edge for raising and lowering the yarn as it is in the act of passing
between the dents of the cleansing and clearing combs for the purposes and
substantially as described and shown in Figs. 1 to 4 of the drawings.
(2) The revolving bar f2 for the purposes and substantially as described and
shown in Fig. 6 of the drawings.
(3) The reciprocating bar in combination with a double rank of my improved
and patented clearing combs substantially as described and illustrated at Fig. 7 of
the drawings.
(4) The double rank of combs arranged to oscillate upon a central pivot for the
purposes and substantially as described and shown at Fig. 8 of the drawings.
(5) The revolving arrangement of cleansing and clearing combs for the purposes
and substantially as described and as illustrated in Fig. 9 of the drawings.
