EDWARD KENWORTHY DUTTON, of St. Ann's Churchyard, Manchester, in the
County of Lancaster, Patent Agent. "IMPROVEMENTS IN APPARATUS EMPLOYED
IN THE REELING OF OR UNWINDING OF YARN OR THREAD FROM RING THROSTLE
BOBBINS, AND OTHER BOBBINS OR PIRNS." [A communication from abroad by
Wilhelm Gustav Heinrich Peltzer, of Kheydt, in the Empire of Germany.]
The Invention relates to the reeling-off or unwinding of yarn and thread from
bobbins in the formation of hanks, or in apparatus for winding, gassing, or doubling,
or in other apparatus wherein the yarn or thread is unwound from the bobbin
upon which it is spun, and is particularly applicable in the treatment of yarn which
has been spun in ring-throstles or has been wound upon bobbins similar to those
used in such throstles. The bobbins are sustained by carriers which are hinged to
a fixed rail or board. In or on each carrier is mounted or fixed a spindle adapted
to receive a bobbin. Above each spindle is a curl or guide through which the yarn
is led as it proceeds from the bobbin. The said curl or guide is fixed in, or to, or
formed upon a part which is hinged to a second rail or board. The upper point or
end of each spindle enters the corresponding curl or guide. Each bobbin carrier is
BO formed and hinged as that when not sustained it yields so as to incline the
spindle and bobbin outwards. So long as the end of the spindle is within the
curl or guide the said spindle is sustained in a vertical, or nearly vertical, or in a
working position. When the guide carrier is raised by the attendant the spindle
end is released and the bobbin carrier yields, whereby the spindle is inclined out-
wardly and the empty bobbin can be readily replaced with a full one. The said
bobbin carrier is then raised and the guide lowered, or raised and lowered, so that
the end of the spindle enters the guide. As the spindle is sustained by bearing
•

page_text: against the inside of the guido, and as the yarn has to pass between the spindle
and guide at the point of contact as each coil is unwound, a degree of tension is
obtained and the tendency to the formation of snarls is checked. In a modifica-
tion the lower end of the spindle is jointed to a rail or to a part attached to the
framing, or the lower end of the said spindle passes through a hole in the said rail
or part, the said hole being larger than the said spindle, and in order that the
spindle may be inclined forwards for doffing. The extreme lower end of the spindle
is enlarged to prevent withdrawal when doffing, or a nut, ball, or collar is screwed,
rivetted, or attached to the said end. This arrangement permits of the spindle to
have a certain amount of freedom in all directions, so that the upper end can move
across and around the said curl or guide. The lower part of the spindle, or a part
fixed or formed thereon, or to or on the said bobbin carrier, is or may be turned to
suit the bore of the lower end of the bobbin. The part to which the guide carrier
is hinged is or may be adjustable upon suitable standards to suit different lengths
of spindles. The yarn passes from the curls or guides over a suitable drag rail, as
is usual.

the said Edward Kenworthy Dutton in the Great Seal Patent Office on the
15th August 1879.
EDWARD KENWORTHY DUTTON, of St. Ann's Churchyard, Manchester, in the
County of Lancaster, Patent Agent. "IMPROVEMENTS IN APPARATUS EMPLOYED
IN THE REELING-OFF OR UNWINDING OF YARNS OR THREAD FROM RING THROSTLE
BOBBINS, AND OTHER BOBBINS OR PIRNS." A communication by Wilhelm Gustav
Heinrich Peltzer, of Rheydt,-in-the-Empire-of-Germany.
The Invention relates to the reeling-off or unwinding of yarn and thread from
bobbins in the formation of banks, or in apparatus for winding, gassing, or
doubling, or in other apparatus wherein the yarn or thread is unwound from the
bobbin upon which it is spun, and is particularly applicable in the treatment of
yarn which has been spun in ring throstles, or has been wound upon bobbins
similar to those used in such throstles. The lower end of each spindle is jointed
to a rail or to a part attached to the framing, or the lower end of the said
spindle passes through a hole in a fixed rail or part, the said hole being larger than
the spindle in order that the said spindle may incline or be inclined forwards for
doffing. The upper end of the spindle enters a curl or guide which is arranged to
be raised when the spindle is to be inclined forwards. The extreme lower end of
the spindle is enlarged to prevent withdrawal from the rail when doffing, or a nut,
ball, or collar is screwed, riveted, or attached to the said end. This arrangement
permits the spindle to have an amount of freedom in all directions from the
perpendicular, so that the upper end can move across and around the said curl or
guide. The lower part of the spindle or a part fixed or formed thereon is or may
be turned to suit the boro of the lower end of the bobbin. The part which carries
the curls or guides is or may be adjustable upon suitable standards to suit
different lengths of spindles. Modifications in the arrangement will be described
hereinafter.
And in order that the said Invention may be fully understood, I have attached
hereunto a Sheet of Drawings made about the full size and marked with letters of
reference. Referring to the said Drawings Fig. 1 represents a side elevation, and
Fig. 2, a front elevation of a single spindle, and of so much of the parts of a
winding frame as is necessary to the proper illustration of the Invention, the
arrangement illustrated being considered to be the most suitable. In the said
Figs. A is the said spindle which is carried by a rail B, which sustains a number of
spindles as will be understood. Upon the said spindle is formed a collar c which is
rounded upon the side next to the rail. The lower part of the spindle passes
through a hole which is drilled or formed in the rail. This hole is a little larger
than the part of the spindle which passes through it, and is bell-mouthed or
chamfered as indicated in the Drawing. On the lower end of the spindle is rivited,
screwed, or secured a button d which serves to attach the spindle to the rail, so
that when the bobbin is doffed the lower end of the spindle is not withdrawn from
the hole in the rail. The arrangement permits of a degree of movement of the
spindle in all directions from the perpendicular. Upon the spindle is fixed or
formed a part e which is turned or formed to fit the bore in the lower end of each
bobbin for which the spindle is adapted. The curl ƒ is fixed to a part g which is
mounted upon a rod h which extends along the frame so as to carry a number of
such parts.. The part g is forked so as to sit upon the rod and is secured in position
by means of a pin which passes through a groove formed in the underside of the
said rod. The said groove is so formed as to permit of the part g being turned
upon the rod into the position somewhat as indicated by the dotted lines in Fig. 1.
The method of mounting the said part or any equivalent part to which the curl
may be fixed, may be varied so long as the arrangement permits of the said curl
being raised clear of the upper end of the spindle. It will be seen that the upper
end of the spindle enters the curl f, and as the said spindle is free to incline in all

page_text: directions from the perpendicular to some extent, it is only kept in a vertical
position or in its arranged working position by means of the said curl, and as a
consequence the tip or upper end of the spindle tends to be at all times in contact
with some part of the inner surface of the said curl. The method of operating with
the apparatus may be described as follows:-Supposing a bobbin to have become
empty, the attendant raises the curl so that it clears the top of the spindle, which
is then free to fall into an inclined position. In order that the spindle shall tend to
assume a position inclining towards the operator, the surface of the rail b is inclined
in the direction indicated in Fig. 1. When the curl is raised as aforesaid, the
spindle being no longer sustained by the said curl assumes a position somewhat as
indicated by the dotted lines in Fig. 1. The empty bobbin may now be removed
and be replaced by a full one. The spindle is then raised into the working
position, and the curl is brought down or lowered into position to retain the
spindle, as indicated by the full lines. The yarn from the bobbin is passed through
the curl and over a drag-rail i, which may be of any ordinary or suitable nature.
As the yarn is unwound from the bobbin it has to pass at each turn around the
spindle, between the spindle end, and the part of the curl with which the spindle
may be in contact, and it has been found that this imparts a suitable degree of
tension to the yarn, and that the formation of snarls is thereby prevented. The
rod h and drag-rail i are attached to brackets, one of which brackets is seen at m.
The said brackets are bolted to suitable standards indicated by n and can be raised
and lowered upon the said standards so as to make the height of the rod h to be
suitable to the average' length of the spindles. Fig. 3 indicates a modification
wherein the lower end of the spindle is hinged or jointed to a rail k, the centre of
the joint being behind the centre line of the spindle, so that the spindle tends to
incline forwards when released from the curl.
Fig. 4 illustrates another modification wherein the spindle is fixed to a part
which is hinged to a fixed rail. This arrangement permits the spindle to incline
only in one direction, and as a consequence, the contact of the upper end of the
spindle with the curl is not so constant as in the example illustrated by Figs. 1
and 2.
Having now fully set forth and indicated the nature of the said Invention, and
means whereby the same may be carried into effect, I would have it to be under-
stood in conclusion that I claim,―
First, the method of mounting the spindles in the apparatus herein indicated,
substantially as and for the purpose or purposes set forth and indicated herein-
before, and in and by the accompanying Sheet of Drawings.
Secondly, so mounting the lower end of the spindle in a hole or slot, in a rail or
part, as that the said spindle tends to incline from its working position, and is
retained in such position by the curl or yarn guide, substantially as and for the
purposes set forth and indicated.
'
And, lastly, the spindle mounted in a bell-mouthed hole formed in a fixed rail or
part, and provided with a collar c and a button d, and retained in working position
by means of a movable curl or yarn-guide, substantially as and for the purposes set
forth and indicated.
In witness whereof, I, the said Edward Kenworthy Dutton, have hereunto set
my hand and seal, this Fourteenth day of August, in the year of our Lord
