page_text: ROBERT HENRY READE Merchant WILLIAM KENNEDY Factory Manager and
JAMES MALLON Factory Foreman, all of York Street Mill, Belfast Ireland do
hereby declare the nature of our invention for AN IMPROVED METHOD AND
APPARATUS FOR CONVEYING, HOLDING, DRYING, AND COOLING WET SPUN YARNS
ON BOBBINS AND PIRNS TO BE DRIED, UNWOUND AND WOVEN to be as follows:-
This invention consists of an improved method of treating the wet spinning
frame bobbins of yarn during the processes of drying and cooling and in the
improved apparatus used for holding and conveying the bobbins to be dried, cooled
and unwound and the pirns to be woven, and it will be understood from the
following description :—
The full bobbins are brought from the wet spinning frames in trays with open
work bottoms having pins formed by raising at a suitable distance apart the
material of which the open work bottom is made, thus forming pins for holding
the bobbins or pirns which is an improvement on the ordinary portable cages or
trays.
Instead of being placed in the drying chambers in theso improved trays with
pins for holding the bobbins, which is the usual way with the ordinary portable
enges, the improved trays are emptied of the bobbins full of wet spun yarns which
are thrown loosely into cages or trays which have open work bottoms without pins
for holding the bobbins, in the drying chamber.
The cylindrical form of the bobbins ensures there being sufficient space about
them to allow of the circulation of air and the consequent removal of the moisture.
The improved trays with pins to hold the bobbins are thus at liberty and can bo
returned to the spinning room to be refilled.
The bobbins full of wet spun yarns are exposed to the heated air in the drying
chamber in the trays with open work bottoms without pins, to allow of the free
circulation of the heated air which is caused to circulate and carry away the
moisture with which it becomes surcharged.

page_text: When the full bobbins have been exposed to this action of the heated nir in the
drying chamber for the required time, they are conveyed to the cooling chamber
in which they are placed loosely in trays having open work bottoms without
pins, to admit of the free circulation of the cool air to which the bobbins are
exposed for a suitable time until they are in proper condition for boing emptied by
being unwound into hanks by reeling or on to spools or pirns which are placed in
the improved trays with open work bottoms with pins for holding the pirns, to bo
conveyed to the looms for weaving as the case may be according to the exigencies
of the case.

COMPLETE SPECIFICATION.
ROBERT HENRY READE, Merchant, WILLIAM KENNEDY, Factory Manager, JAMES
MALLON, Factory Foreman, all of York Street Mill Belfast do hereby declare the
nature of our invention for AN IMPROVED METHOD AND APPARATUS FOR CON-
VEYING, HOLDING, DRYING, AND COOLING WET SPUN YARNS ON BOBBINS AND
PIRNS TO BE DRIED, UNWOUND, AND WOVEN and in what manner the same is to
be performed, to be particularly described and ascertained in and by the following
statement:-
This invention consists of an improved method of treating the wet spinning
frame bobbins of yarn during the process of drying and cooling and in the
improved apparatus used for holding and conveying the bobbins to be dried, cooled
and unwound and the pirns to bo woven.
The process and appliances will be understood from the following description,
reference being had to the drawing herewith in which the same letters and figures
of reference always apply to the same or like parts.
Figures 1 and 2 show the form of portable cage, employed to receive the bobbins
from the wet spinning frames, in which there is a pin for each bobbin.
Figures 3 and 4 shew the forin of portable cage employed to hold the bobbins
during the drying or cooling process.
Figures 5. 6. 7 and 8 shew forms of portable cages employed for carrying bobbins
or pirns to be woven where it is necessary that there should be a separate pin for
each bobbin or pira
The full bobbins are brought from the wet spinning frames in trays or portable
cages with open work bottoms having pins or projections (a) formed in them at
regular intervals by raising or folding the sectoral sectioned wire of which the
open work bottom is formed in a sort of loop at the top so that the projection or
pin (a) is actually larger at the point than at the base and so they retain the
bobbins or pirns more effectually than if made taper or even parallel which is the
usual method.
These loops or projections (a) are formed in the sectoral sectioned wire of which
the open work bottom is formed at suitable distances apart and the wires with
loops or projections are interlaced alternately with each other so as to mutually
support, and steady each other and so as to maintain the projecting pins (a) at
regular intervals.
Instead of being placed in the drying chambers in these trays or portable cages
with pins for holding the bobbins, the portable cages with pins (a) are emptied of
the bobbins full of wet spun yarns which are thrown loosely into cages or trays
which have open work bottoms without pins as illustrated in figures 3 and 4.
The cylindrical form of the bobbins ensures there being sufficient space about them
to allow of the circulation of air and the consequent removal of the excessive
moisture in the yarn whilst in the heated drying chamber which is fitted with
convenient racks for the reception of the trays or cages with open work bottoms
without pins as shewn in figures 3 and 4.

page_text: The trays with pins to hold tho full bobbins are thus set at liberty by being
emptied and can be returned without delay to the spinning room to be refilled.
When the full bobbins in the cages with open work bottoms without pins
Figures 3 and 4 have been exposed to the action of the heated air in the drying
chamber for the required time they are conveyed to the cooling room in which
they are placed loosely in similar trays having open work bottoms without pins,
which permit the free circulation of the ccol air and to which the bobbins full of
yarn are exposed for a suitablo time until they are in proper condition for being
emptied by being unwound into hanks by reeling, or on to spools or pirns. If
wound on to pirns the pirns are placed in an improved form of tray with open
work bottoms formed by interlacing the wire of which they are made and which is
bent or folded at regular intervals so as to form projections or pins (a) as already
described, these trays are used to convey the pirns to the weaver or wherever they
may be wanted.
The improved form of tray or portable cage for pirns is illustrated in figures 5.
G 7 and 8 in both theso cases the looped form of projecting pin (a) and the
alternate interlacing of the wire forming the open work bottom already described
is adopted.
To give facility for carrying these trays and also to protect the pins or loops for
holding full or empty pirns a frame (b) and handle (c) is raised above the pirns
as shewn in figures 5 and 6 or the handles (d) of the pirn cages are placed on two
sides of the trays as shewn in figures 7 and 8.
Having now particularly described and ascertained the nature of our said
. invention and in what manner the same is to be performed wo declare that what
we claim is
1st The construction of portable cages with projections on open work bottoms of
the shape and for the purpose described.
2nd The drying or cooling of wet spun yarn on bobbins thrown loosely into open
work bottomed cages without pins.
