PROVISIONAL SPECIFICATION.
Improvements in Arrangements applicable to Ring Spinning and
Doubling Frames for Facilitating the Doffing thereof.
We, GEORGE SHEPHERD, of Bacup in the County of Lancaster, Cotton Spinner
and Manufacturer, and HENRY MIDGLEY, of the same place, Manager, do hereby
declare the nature of this invention to be as follows:-
When a set of spools or pirns are full of yarn or thread in ring spinning and
doubling frames, they have to be removed from the spindles and replaced with
empty spools or pirns which operation is termed "doffing."
Our invention relates to arrangements for facilitating this doffing operation so
that it may be effected more conveniently than hitherto and in less time, by which
saving of time in doffing there is consequently a greater production of yarn or
thread.
Our invention consists in applying to the front of the frames so as to be
readily removed and replaced when required, arrangements having receptacles for
holding in a convenient position empty spools or pirns, and a trough or receptacle
for holding spools or pirns filled with yarn or thread.
The receptacles for empty spools are at a convenient distance apart, and will
hold as many spools or pirns as there are spindles between the receptacles and may
be made to hold as many as can be conveniently taken in one hand. These
receptacles are in an inclined position or otherwise so that all the empty spools
pirns in one receptacle can be grasped at the same moment by one hand of the
attendant.
or
The empty spools or pirns are placed in the receptacles by the attendant between
the times of doffing when not otherwise occupied.
The full spools are drooped into the trough or receptacle for them and can when
the attendant is at liberty be readily pushed along the trough until they come to a
gap in it from which they drop into a box, skip or other suitable receptacle
below the trough.
We prefer to make the receptacles for empty spools or pirns and the trough,
out of tinned plate, having hooks or brackets secured at intervals which catch upon
the lower rail of the frame and are secured by a turn button against the upper
rail-but these receptacles and troughs may be made of other material and arranged
and secured in any other convenient manner to the front of the frame.

Improvements in Arrangements applicable to Ring Spinning and
Doubling Frames for Facilitating the Doffing thereof.
We, GEORGE SHEPHERD, of Bacup, in the County of Lancaster, Cotton
Spinner and Manufacturer, and HENRY MIDGLEY of the same place, Manager,
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 :—
When a set of spools or pirns are full of yarn or thread in ring' spinning and
[Price 821

page_text: doubling frames, they have to be removed from the spindles and replaced with
empty spools or pirns which operation is termed "doffing."
Our invention relates to arrangements for facilitating this doffing operation so
that it may be effected more conveniently than hitherto and in less time, by which
saving of time in doffing, there is consequently a greater production of yarn or
thread, also a considerable reduction in the cost of pirns, spools or bobbins.
Our invention consists in applying to the front of the frames so as to be readily
removed and replaced when required, arrangements having receptacles for holding
in a convenient position empty spools or pirns, and a trough or receptacle for
holding spools or pirns filled with yarn or thread.
The receptacles for empty spools are at a convenient distance apart, and will
hold as many spools or pirus as there are spindles between the receptacles, and may.
be made to hold as many as can be conveniently taken in one hand. These
receptacles are in an inclined position or otherwise, so that all the empty spools or
pirns in one receptacle can be grasped at the same moment by one hand of the
attendant.
The empty spools or pirns are placed in the receptacle by the attendant between
the time of doffing, when not otherwise occupied.

The full spools are dropped into the trough or receptacle for them and can when
the attendant is at liberty be readily pushed along the trough until they come to a
gap in it from which they drop into a box, skip or other suitable receptacle below
the trough.
We prefer to make the receptacle for empty spools or pirns and the trough, out
of tinned plate, having hooks or brackets secured at intervals, which catch upon the
lower rail of the frame and are secured by a turn button against the upper rail;
but these receptacles and troughs may be made of other material and arranged and
secured in any other convenient manner to the front of the frame.
"
Fig. 1, is a front elevation showing so much of the parts of a "ring frame as
will be necessary for fully explaining our invention, and
Fig. 2, is a sectional elevation in a plane at a right angle to the plane of
Fig. 1.
In Fig. 1, a, is the rail in which the spindles are secured, such spindles being
those known as "self contained" that is to say, the screw threaded stem of the
part d, forming the tubular bearing for the spindle is passed through a hole in the
rail a, and is secured thereto by a screw nut d*, and the spindle having the sleeve d¹,
carrying the warf d², is inserted in the tube forming its bearing.
In Fig. 1, only one spindle is shown with an empty spool, pirn or bobbin d³, upon
it at one end, and the positions of other spindles are only indicated in Fig. 1, by,
centre lines d'.
This Fig. 1, shows only a part of one side of a "ring" frame which are made of
any desired length.
b, represents the rail below the spindle rail à; and c, the copping or ring rail,
carried upon the upper ends of rods, not shown, at- intervals sliding up and down
in bearings in the rails a and b.
Those parts of the drawings above referred to are ordinary and well known
parts of "ring frames."
Between the rails a and b, there is a thin plate e, formed by preference of
tin-plate, the front of which is also made into a trough e', as shown best in
Fig: 2.
These trough plates e and el, are made of any desired and convenient length
with a bracket e², near each end, which brackets when in position hook. upon the
upper. side and back edge of the rail b, as shown best in Fig. 2, and each length of
plate trough e and e', is secured when in position by buttons e³, turning on screws
or pins inserted and secured in the front of the spindle rail a.
The vertical plate e, of each trough, has a hole in it at intervals to which, a
tube e, is secured, as shown best in Fig. 2, which tubes et, form pockets.or
receptacles into which the empty tubes, pirns or bobbins f, are inserted, the small

page_text: ends of the tubes, pirns or bobbins being downwards, and the large or head ends-
upwards in an inclined position by preference.
One only of these tubes, pirns or bobbins is shown in the receptacle in Fig. 2,-
and in one receptacle shown in Fig. 1, but seven are inserted in each receptacle,.
because seven spindles are intended to be served by each pocket or receptacle but
this may be varied if desired, but we find that seven spindles and seven pirns for one:
receptacle is a convenient number.
The tubes, pirns or bobbins in one pocket or receptacle in an inclined position,
are readily grasped by one hand, and the operative removes the full pirns or
bobbins with one hand and replaces them by empty pirns or bobbins by the other
hand when doffing, the full pirns or bobbins being dropped into the trough to be
pushed along when the doffing operation is finished to the end of the trough at
either end of the frame or to suitable gaps in the bottom of the trough e', through
which gaps, the full pirns or bobbins will drop into a skip, box or other receptacle
below, placed to receive them.
The empty pirns or bobbins are filled into the receptacles ready for the net.
"get "
to be doffed, at. intervals, while the operative is not otherwise occupied
while the frame is spinning.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we.
claim is.
1. The combination with "ring frames" of arrangements, for holding a number-
of empty pirns or bobbins, at intervals substantially as and for the purpose.
hereinbefore described.
"
2. The combination with "ring frames of arrangements, for holding a number-
of empty pirns or bobbins, at intervals with a trough or receptacle for pirns or
bobbins filled with yarn or thread, substantially as and for the purpose hereinbefore
described.
3. The combination with "ring frames" of arrangements or devices, for holding
a number of empty pirns or bobbins at intervals, with a trough or receptacle for
pirns or bobbins filled with yarn or thread substantially as and for the purpose
hereinbefore described and illustrated by the drawings.
