WILLIAM WALTON URQUHART and JOSEPH LINDSAY, both of Dundee, in the
County of Forfar, North Britain, Engineers. IMPROVEMENTS IN MACHINERY
FOR DRESSING AND BEAMING YARNS."
This Invention has for its object to improve the arrangement of the various parts
of machinery used for dressing and beaming yarns, and in carrying it out,
according to one modification, parts are provided for separately dressing and drying
two sets of yarns, which are afterwards beamed together or wound upon one
beam. The beaming apparatus occupies a central position, and the separate dressing
and drying sections are arranged towards opposite ends. The several sections of
the apparatus are made with distinct and detached frames designed to give the
attendant workers convenient access to the various parts, instead of there being, as
in many existing machines, one or more long unbroken framings involving loss of
time in getting from one part to another. At each end of the machinery the yarns
drawn in the usual way from a bank or frame of bobbins are passed between rollers,
the lower one of which dips into a trough of starch or other dressing material, and
aro next subjected in a usual manner to a rotating brush. The yarns then leave
the dressing frame and proceed either to a single large steam-heated drying
cylinder, or to a pair of such cylinders mounted one above the other on a separate
framing, and when more than two drying cylinders are used another separato
framing is provided to carry the additional cylinder or cylinders. From the last
drying cylinder the yarns are led at a considerable elevation to guide rollers at the
top of the beaming frame, the guide rollers for the two sets of yarns from opposite
ends of the machinery being near together, and the yarns passing down between them
to a single lower guide roller, from which last they proceed together to the beam,

page_text: A pressing roller with raising and lowering gear is provided in the usual way for
acting on the yarn as it is being wound on the beam. Whilst the winding action
is proceeding the beam is supported by movable brackets which can be moved out
of the way when the beam is being entered or removed, the beam being temporarily
supported by chains and lifting gearing. The framing of this beaming section is
specially arranged to facilitate the introduction and withdrawal of the trucks or
barrows employed for conveying the beams to and from the machine. At one side
there is a broad vertical side frame, but at the other side the frame is made with
its lower part one-sided, but with a foot extending from the bottom of the complete
side so as to be under the middle parts of the machine. With this construction a
considerable space is left clear between one side of the beaming section and the
adjacent drying section, and in this space the truck or barrow can be conveniently
turned after receiving the beam without requiring to he moved out transversely
before being turned. Rotatory fans are provided near the yarns at the parts where
they leave the drying cylinders to drive off vapor; and between the drying
cylinders and the beaming mechanism the yarns pass at a sufficient height to allow
an attendant worker to pass freely across beneath the yarns.

by the said William Walton Urquhart and Joseph Lindsay in the Great Seal
Patent Office on the Sth March 1881.
WILLIAM WALTON URQUHART and JOSEPH LINDSAY, both of Dundee, in the
County of Forfar, North Britain, Engineers. "IMPROVEMENTS IN MACHINERY FOR
DRESSING AND BEAMING YARNS."
Our said Invention has for its object to improve the arrangement of the various
parts of machinery used for dressing and beaming yarns, and in carrying it out,
according to one modification, parts are provided for separately dressing and drying
two sets of yarns, which are afterwards beamed together or wound on one beam.
The beaming apparatus occupies a central position, and the separate dressing and
drying sections are arranged towards opposite ends. The several sections of the
apparatus are made with distinct and detached frames designed to give the
attendant workers convenient access to the various parts, instead of there being, as
in many existing machines, one or more long unbroken frainings involving loss of
time in getting from one part to another. The framing of the beaming section
is specially arranged to facilitate the introduction and withdrawal of the trucks or
barrows employed for conveying the beams to and from the machine.
And in order that our said Invention, and the manner of performing the same,
may be properly understood, we hereunto append a Sheet of explanatory Drawings
to be hereinafter referred to, and representing our improved machinery.
Figure 1 on the accompanying Sheet of Drawings is a general plan of the

page_text: dressing and beaming machinery, and Figure 2 is a corresponding side elevation;
Figure 3 is an elevation showing certain details connected with the beaning
apparatus, and Figure 4 is a diagram to be hereinafter referred to. In these
Drawings the same reference numerals are used to mark the same or like parts
wherever they are repeated.
At each end of the machinery the yarns 5 drawn in the usual way from a bank
or frame of bobbins, which is not shown in the Drawing, are led to a dressing
machine or frame G, and therein passed between rollers 7, the lower one of which
dips in a trough 8 of starch or other dressing material, and are next subjected in
a usual manner to a rotating brush 9. In some cases however the yarns are not
subjected to the action of a rotating brush. The yarns 5 on leaving the dressing
frame G proceed either to a single large steam-heated drying cylinder, or to a pair
10, 11, of such cylinders mounted one above the other on a separate framing 12.
From the last drying cylinder 11 the yarns 5 are led at a considerable elevation to
guide rollers 13 at the top of the beaming frame 14, the guide rollers 13 for the two
sets of yarns from opposite ends of the machinery being near together, and the
yarns 5 passing down between them to a single lower guide roller 15, from which
last they proceed together to the beam 16. A pressing roller of the ordinary
elongating and shortening kind may be provided for pressing on the yarns as they
become wound on the beam 16, but we prefer to employ an improved arrangement,
which will be understood from Figure 3 taken in connection with Figures one and
two. For pressing immediately on the yarn on the beam 16, we employ a tube or
hollow cylinder 17, made of a length to fit easily between the end discs of the
beam 16; and we provide separate tubes (17) for the different sizes of beam used
in connection with the dressing and beaming machinery. The tube or cylinder 17
is itself pressed on by two rollers 18, carried by brackets 19 formed or fixed on a
horizontal bar 20 placed transversely with its ends guided by the side frames 21, 22.
On a rod 23, extending between the brackets 19 at opposite sides, there are movable
hooks 24, which enter the ends of the tube or cylinder 17, and support it when it
is not resting on a bean 16. The bar 20 has vertical rack-toothed bars 25 fixed
to it, and it is raised and lowered by their means, they gearing with pinions on a
shaft 26, geared by a spur wheel and a pinion to a shaft 27, having a hand-wheel 28
fixed to it; these parts and other accessory details, excepting the cylinder 17,
on rollers 18 being similar to the corresponding parts of existing beaming machines.
Whilst the winding action is proceeding, the beam 16 is supported in movable
brackets 29, which can be moved out of the way when the beam is being entered or
removed, the beam being temporarily supported by chains and lifting gearing
in the usual way. The framing 21, 22, of this beaming section is especially arranged
to facilitate the introduction and withdrawal of the trucks or barrows employed for
conveying the beams 10 to and from the machine. At one side there is a broad
vertical side frame 22, but at the other side the frame 21 is made with its lower
part one-sided, but with a foot 30 extending from the bottom of the complete side
so as to be under the middle parts of the machine. With this construction a
considerable space is left clear between one side of the beaming section 14 and the
adjacent drying section 10; and in this space the truck or barrow can be conveniently
turned after receiving the beam without requiring to be moved out transversely
before being turned. Rotatory fans 31 are provided near the yarns 5 at the parts
where they leave the drying cylinders 10, 11, to drive off vapor; and between the
drying cylinders and the beaming mechanism the yarns pass at a sufficient height
to allow an attendant worker to pass freely across beneath the yarns.
It is to be understood that various details that have not been bereinbefore
referred to, are to be applied in any suitable manner usual with existing machinery
for the same purpose. The main driving gearing is arranged at the side of the
central section or beaming frame 14 opposite to that at which the beam trucks or
barrows are entered and withdrawn, and longitudinal shafting 32 communicates
motion to the moving parts of the end sections or dressing frames 6, this shafting 32

page_text: being placed in a low position so that attendant workers can easily step over it, or
over a projecting casing enclosing it.
When more than two drying cylinders (10, 11) are required, a separate framing
may be added for carrying each additional cylinder or pair of cylinders; or a framing
with one additional cylinder may be placed above, or constructed as an upward
extension of each dressing frame 6, as indicated by dotted lines at 33, in Figure 2.
When this modified arrangement is adopted, the yarns are by preference led round
the drying cylinders, in the manner indicated in the diaphragm, Figure 4.
Having thus particularly described our said Invention, and the manner of
performing the same, we have to state that we do not restrict ourselves to the precise
details herein described or delineated, but that what we believe to be novel and
original, and claim as the Invention secured to us by and in terms of the herein-
before in part recited Letters Patent, is,—
1. The arranging or combining together of the parts of machinery for dressing
and beaming yarns, substantially in the improved manner herein before described.
2. The making of the several sections of the dressing and beaming machinery
with distinct and detached frames, substantially as and for the purposes herein before
described.
3. The constructing of the framing of the central or beaming section with
one-side-frame--one-sided,..substantially as and for the purposes bereinbefore
described.
4. The combination of the tube or hollow cylinder (17) with the two rollers (18)
for pressing the yarns upon the beam-as-they-are-being_wound thereon, as herein-
