We, WILLIAM ROBERTSON, and JAMES GUTHRIE ORCHAR, of Wallace Foundry,
Dundee, in the County of Forfar, North Britain, Engineers, do hereby declare the
nature of this Invention to be as follows: that is to say:
Our said Invention relates to machinery for dressing and beaming yarns, and its
object is to improve the construction or arrangement and the operation of the part of
the machinery by which the yarns, after being dressed and dried, are beamed or wound
on a beam or roller ready for the loom. Our improvements are applicable to various
widths of machine, and are especially advantageous in the case of wide machines.
Our improvements are also applicable for beaming undressed yarns.
In carrying out our Invention the beaming section of the machinery is arranged as
usual in machinery to which our improvements are applicable, upon a framing which
occupies a middle position between two other framings carrying the dressing and
drying apparatus, there being spaces between the middle framing and. the others to
allow the attendant, workers to pass across. The two portions of yarns from the two
dressing framings are led by guide rollers in the usual way so as to be wound together
upon the beam, which is placed in the centre of the middle framings. As the yarns
are being wound upon the beam they are pressed upon it by upper and lower rollers
which are in the form of hollow cylinders or tubes, and are of a length to fit in
between the end disks or flanges of the beam. In one modification one tube is above
the beam and the other beneath it, the latter giving support, and each meeting the
pressure of the other, and preventing the beam from yielding in the middle as it is
liable to do when of considerable length. The pressing tubes may in some cases be
placed at the sides of the beam, but are in all cases, by preference, diametrically
opposite to cach other. In the arrangements with the pressing tubes above and below
the beam, the lower tube is, in one modification, supported in a fixed position on two
or more pairs of rollers on shafts carried in bearings on brackets fixed to the framing
there being one or more intermediate brackets as well as end brackets when the
machine is made for long beams. When the lower tube is in a fixed position the
beam itself as well as the upper tube must rise as the diameter of the yarn on the
beam increases; and for this purpose the end spindle or journal to which the driving

page_text: power is applied is entered into the inner end of a short shaft carried in a long bearing
in a frame piece which is movable vertically in guides upon one of the end frames of
the machine. The outer end of the short shaft has fixed on it a spurwheel gearing
with a smaller spurwheel which latter is fixed to a larger spurwheel, and the two spur-
wheels thus fixed together are kept in gear with the spurwheel on the short shaft by a
link connecting their centre to the tubular bearing of the short shaft in such a way as
to allow of the vertical movement of that shaft along with the beam. The larger
spurwheel of the two fixed together gears with a spurwheel on a short shaft or stud
in a fixed position, and to which the centre of the two spurwheels is connected by a
link allowing of a slight horizontal movement of those wheels in accommodating
themselves to the movement of the beam.
The upper pressing tube is held in position and pressed downwards by pairs of
rollers on shafts carried by brackets upon a girder extending from one end frame to
the other and working in vertical guide slots in the end frames. The ends of the
girder are connected to vertical racks in convenient positions outside of the lower parts
of the end frames; and these racks have gearing with them pinions on a shaft which
can be turned by means of a spurwheel and pinion for raising or lowering the racks
and parts to which they are connected. The spindle or journal at the end of the
beam opposite to the driving end is simply entered into a vertical guide slot in a
bracket placed a little within the end frame, the parts at both ends being arranged to
allow of conveniently entering and removing the beam.
In another modification the position of the centre of the beam is fixed and the
lower pressing tube descends whilst the upper one rises. The movement of the lower
tube is controlled by racks like those hereinbefore described for the upper tube, and
these racks gear with the same pinions but on opposite sides so as to move reversely,
In this case the upper tube and its accessories will counterbalance the lower tube and
its accessories, whilst any desired pressure can be applied by weights arranged to act
through the pinion shaft or in any other convenient way.

Improvements in Machinery for Dressing and Beaming Yarns.
We, WILLIAM ROBERTSON, and JAMES GUTHRIE ORCHAR, of Wallace Foundry
Dundee, in the County of Forfar, North Britain, Engineers, do hereby declare the
nature of this invention and in what manner the same is to be performed, to be particu-
larly described and ascertained in and by the following statement, that is to say:―
Our said Invention relates to machinery for dressing and beaming yarns, and its
object is to improve the construction or arrangement and the operation of the part of
the machinery by which the yarns after being dressed and dried, are beamed
or wound on a beam or roller ready for the loom. Our improvements are
applicable to various widths of machine, and are especially advantageous in the case
of wide machines. Our improvements are also applicable for beaming undressed
yarns.
In particularly describing our improvements we will hereinafter refer to five sheets
of explanatory drawings which are hereunto appended and which represent two
modifications of machinery as mado according to our Invention. Figure, 1, on
sheet, 1, is a diagram showing the general arrangement of the complete machine.
Figure, 2, on sheet, 2, is an end elevation of one modification of the beaming
mechanism, figure, 3, on sheet, 3, being a side elevation corresponding to figure, 2,
but drawn to a smaller scale; whilst figures, 4, and 5, on sheets, 4, and 5, are similar
views of the second modification of the beaming mechanism. In these drawings tho
same reference numerals are used to mark the same or like parts wherever they are
repeated.
In carrying out our Invention the beaming section of the machinery is arranged as
usual in machinery to which our improvements are applicable, upon a framing, 6,
figure, 1, which occupies a middle position between two other framings, 7, carrying
the dressing and drying apparatus; there being spaces between the middle framing, 6,
and the others, 7, to allow the attendant workers to pass across. The two portions of
yarns, shown by peculiarly dotted lines, 8, are led from the two dressing framings, 7,
in the usual way round guide rollers, 9, 10, so as to be wound together upon the
beam, 11, which is placed in the centre of the middle framing, 6.
As the yarns are
being wound upon the beam, 11, they are pressed upon it by upper and lower
rollers, 12, 13, (figures, 2, and 3,) which are in the form of hollow cylinders or tubes,
and are of a length to fit in between the end disks or flanges of the beam, 11. In
the modification shown in figures, 2, and 3, one tube, 12, is above the beani, 11, and
the other, 13, beneath it, the latter giving support, and each meeting the pressure of
the other, and preventing the beam from yielding in the middle as it is liable to do
when of considerable length. The lower tube, 13, is supported in a fixed position on
two or more pairs of rollers, 14, on shafts, 15, carried in bearings or brackets, 16,
formed on horizontal frame pieces, 17, which are fixed to the end frames or gables; 18,
of the machine, there being one or more intermediate brackets, 16, as well as
end brackets when the machine is made for long beams. The lower tube, 13, being
in a fixed position the beam, 11, itself as well as the upper tube, 12, must rise
as the diameter of the yarn on the beam increases; and for this purpose the end

page_text: spindle or journal to which the driving power is applied is entered into the inner
end of a short shaft carried in a long bearing, 19, in a frame piece, 20, which is
movable vertically in guides upon one of the end frames, 18, of the machine. The
outer end of the short shaft has on it a spurwheel, 21, gearing with a smaller spur-
wheel, 22, which latter is fixed to a larger spurwheel, 23, or on the same shaft or
spindle, and the two spurwheels, 22, 23, thus fixed together are kept in gear with the
spurwheel, 21, on the short shaft by a link, 24, connecting their centre to the tubular
bearing, 20 of the short shaft in such a way as to allow of the vertical movement of
that shaft along with the beam, 11. The larger, 23, of the two spurwheels fixed
together gears with a spurwheel, 25, on a short shaft or stud in a fixed position, and to
which the centre of the two spurwheels, 22, 23, is connected by a link, 26, allowing of
a slight horizontal movement of thoso wheels in accommodating themselves to the
movement of the beam. The spurwheel, 25, has in gear with it a pinion, 27, on the
first-motion shaft, 28, which has on it fast-and-loose pulleys, 29, for a driving belt.
The upper pressing tube, 12, is held in position and pressed downwards by pairs of
rollers, 30, on shafts, 31, carried by brackets, 32, upon a girder, 33, extending from
one end frame, 18, to the other, and working in vertical guide slots in the end frames.
The ends of the girder, 33, are connected by means of crosshead blocks, 34, and
rods, 35, to vertical racks, 36, in convenient positions outside the lower parts of the
end frames, 18; and these racks, 36, have gearing with them pinions, on a shaft, 37,
which can be turned by means of a spurwheel, 38, and pinion, 39, for raising or
lowering the racks, 36, and parts to which they are connected: A ratchet wheel with
pawl' is provided in connection with the pinion, 39, for holding up the racks, 36, and
parts connected to them. In figures, 2, and 3, the beam, 11, is represented as full and
the upper tube, 12, as lifted a little distance above it to allow of its being removed
from the machine. The upper tube, 12, when not resting on the beam is suspended
by hooks, 40, entered in its ends, these hooks being formed on bosses fitted on a rod
fixed to the brackets, 32, and extending along between the shafts, 31, and being
adjustable on the rod to suit tubes of different lengths. The spindle or journal, 41,
at the end of the beam, 11, opposite to the driving end is entered into a vertical guide
slot in a standard, 42, fixed on the frame piece, 17, near the end frame, 18, but
arranged to allow of conveniently entering and removing the beam. It is to be
understood that parts of the machinery which have not hereinbefore been referred to,
are constructed or arranged as in existing beaming machines.
In the other modification which is shown in figures, 4, and 5, the centre of the
beam, 11, retains a fixed position whilst the beaming operation proceeds; and as the
diameter of the yarn on the beam increases the lower pressing tube, 13, descends
whilst the upper one, 12, rises. The racks, 36, which move with the upper pressing
tube, 12, are placed at the upper parts of the end frames, 18, along with the gearing
and parts connected with them instead of being at the lower parts as in figures, 2,
and 3; and handwheels, 43, are fixed on the ends of the shaft of the pinions, 39, for
raising and lowering the racks, 36, and parts connected with them. The movement of
the lower tube, 13, is controlled by racks, 44, formed segmentally on the outer ends of
levers, 45, which are centered on studs fixed to the end-frames, 18, and which have
their inner ends connected by links, 46, to a girder, 47. This girder, 47, replaces the
frame piece, 17, of the first modification, and is made with ends working vertically in
guides formed on the inner sides of the end frames, 18. The racks, 47, have gearing
with them pinions on a shaft, 48, which has handwheels, 49, fixed on its ends, and
which has also ratchet wheels, 50, fixed on it to allow of its being retained in any
position by pawls. The shaft, 48, has also fixed on it pulleys, 51, on which are fixed
and wound belts, 52, passing round guide pulleys and down to a weight or weights,
which are such as acting through the shaft, 48, and its pinions on the racks, 44, and
levers, 45, to cause the lower tube, 13, to be pressed upwards with the requisite
pressure against the under side of the beam, 11.
Instead of having the racks, 36, and 42, of the upper and lower tubes, 12, 13,
respectively controlled by separate gearing they may be arranged to gear with the
same pinions but on opposite sides; and in that case the upper tube and its accessories

page_text: will balance the lower tube and its accessories whilst any desired pressure can be
applied by weights arranged to act through the pinion shaft or in any other convenient
way. The pressing tubes may in some cases be placed at the sides of the beam, but
they are in all cases, by preference placed diametrically opposite to each other.
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 dressing and beaming yarns or for only beaming yarns, the
combining or arranging of the beaming mechanism substantially in the improved
manner herein before described.
2. The combining of two diametrically opposite pressing tubes with other parts of
the beaming mechanism substantially as hereinbefore described with reference to
figures, 2, and 3, of the accompanying drawings.
3. The combining of two diametrically opposite pressing tubes with other parts of
the beaming mechanism substantially as hereinbefore described with reference to
figures, 4, and 5, of the accompanying drawings.
