page_text: LETTERS PATENT to George Perkins, George Wimpenny and Joseph Hampson
Evans all of the City of Manchester in the County of Lancaster for an
Invention of "IMPROVEMENTS IN RING-SPINNING MACHINERY "
PROVISIONAL SPECIFICATION left by the said George Perkins, George
Wimpenny and Joseph Hampson Evans at the Office of the Commissioners of
Patents on the 16th June 1882.
GEORGE PERKINS, GEORGE WIMPENNY and JOSEPH HAMPSON EVANS all of the
City of Manchester in the County of Lancaster, "IMPROVEMENTS IN RING-SPINNING
MACHINERY
"
Our Invention relates to ring spinning machinery and in the first place to the
ring and traveller used in such machinery and more particularly to the travellers
which are intended to guide the yarn more closely to the cop than in the case of
the old travellers which had no movement towards the spindle. One description of
traveller which we employ is carried within a deep groove which is cut in the
inner surface of the ring. The traveller may be varied in form so long as each
end runs in the groove and the part which guides the yarn is free to move towards
and from the spindle. A simple form consists of a single piece of wire bent at one
end into a hook or eye through which the yarn passes to the guide which is formed
by bending or looping the wire. In a modification the guide is free to move upon
the traveller so as to be self adjusting. The traveller or guide in some cases may be
made from sheet metal. Another description of traveller consists of a light carriage
which carries an arm which swivels upon a vertical axis. The said carriage is
formed with clips which enter inner and outer grooves formed in the ring. The
free end of the said arm runs in the inner groove which is made sufficiently deep
to retain the said end at the same time that the said arm which carries or is formed
with the yarn guide is free to swivel. The said arm may be made of wire which
is coiled at one end and is mounted by such end upon a wire or pin upon the
carriage the said wire or pin being formed to serve as the first guide through which
the yarn passes to the guide upon the arm. In the second place we arrange for the
lower end of the bolster of the upper bearing to be close to the upper surface of
the whorl" or warve and we turn or form a groove on the said lower end of the
bolster. When it is desirable to stop any spindle the band can be slipped out of
the groove in the "whorl " into the said groove on the bolster.

SPECIFICATION in pursuance of the conditions of the Letters Patent filed
by the said George Perkins George, Wimpenny and Joseph Hampson Evans
in the Great Seal Patent Office on the 15th December 1882.

Our Invention relates to ring spinning machinery and in the first place to the
ring and traveller used in such machinery and more particularly to the travellers
which are intended to guide the yarn more closely to the cop than in the case of
the old travellers which had no movement towards the spindle. The traveller
which we employ is carried within a deep groove which is cut or formed in
the inner surface of the ring. Each end of the traveller runs in the groove and
the part which guides the yarn is free to move towards and from the spindle. The
traveller may consist of a single piece of wire bent at one end into a hook or eye
through which the yarn passes to the guide which is formed by bending or looping
the wire; or the traveller or the guide upon the traveller may be made from sheet
metal. In the second place we arrange for the lower end of the bolster of the
upper bearing to be close to the upper surface of the whirl or warve and we
turn or form a groove on the said lower end of the bolster. When it is desirable
to stop any spindle the band can be slipped out of the groove in the "whirl" into
the said groove on the bolster.

In order that our Invention may be fully understood we have attached hereunto
a sheet of drawings made to a scale of about twice the full linear dimensions of
the examples selected for illustration. In the said drawings Fig: 1 which is partly
in section illustrates the whole of our Invention. Fig 2 is a plan view of a ring
with one of our improved travellers in position and Fig: 3 illustrates a modification
in the form and method of producing the traveller. Fig: 4 illustrates a modification
in the ring. In Fig 1 a, a, are portions of two ordinary spindles which are mounted
to revolve in bolsters or long collars b, b, which are secured to a rail c as is usual.
The rings dare mounted in ring brackets e which are secured to a back lifting
rail in accordance with a former invention for which Letters Patent number 876
of this current year have been granted to us this being the method of mounting
which we prefer but the rings may be mounted in the usual or in any suitable
manner, One of the rings is represented in section to the right-hand in Fig 1
wherein it will be seen that a deep groove or recess d¹ is turned or cut in the ring
penetrating for some distance from the bore of the ring the form of the ring being
made suitable to the production of this groove. The traveller g is made of steel
wire bent into the form clearly represented in Figs 1 and 2. One end of the wire
is bent into a hook gl and a part intermediate between the ends is looped and bent
to form a yarn guide g³. The ends which run in the groove are curved or bent as
shown or into any suitable form which will impart steadiness to the traveller and
will furnish sufficient wearing surface. The guide g¹ may be made as a circular
eye or curl or be of any suitable form and the second guide g² may be varied in
form or may be made as a separate piece and be attached to the limb of the
traveller or be mounted to slide thereon so as to be self-adjusting. The traveller is
sprung into its position within the groove the curved form of the limb of the
traveller facilitating its insertion within the groove. In Fig: 3 the traveller is
represented as being made of sheet metal and for this purpose we prefer to use
sheet steel. In practice we should punch blanks from sheet metal and stamp or
form these blanks into the required shapes. By this formation we obtain an

page_text: increased area of wearing surface at the ends which run in the groove. We may
harden or harden and temper either the ring or the traveller or both. Fig: 4
illustrates a form of ring which may be used with our improved traveller. In this
example the ring is formed in two parts d and d¹. This formation is suitable for
adoption when making hardenened steel rings as the two parts can be separately
polished and finished after the hardening process in order to obtain a smooth
surface within the groove The part d' may or may not be removed for the
introduction of the traveller It will be seen on reference to Fig 1 that the lower
ends of the bolster are extended dowards to the "whirls" h, h or the latter are
brought close up to the lower ends of the bolsters. A groove i is formed in
the outer surface of the end of the bolster and the upper flanch of the "whirl" is
made smaller than usual so that the driving band can be readily slipped out of the
groove in the "whirl" into the groove i on the bolster whenever it is desirable to
stop one of the spindles. By this means we are enabled to stop a single spindle
without arresting the motions of the others. In some cases instead of forming a
narrow groove, the lower part of the bolster might be reduced in diameter for a
certain distance as shewn on the bolster to the left in Fig: 1.
Having now fully set forth the nature of our said Invention and the manner in
which we carry the same into practical effect we would have it to be understood
that we claim in ring-spinning machinery :-
:―
First the traveller g in connection with an internally grooved ring substantially
as set forth and indicated hereinbefore and in and by the accompanying drawings.
Secondly a traveller made of wire bent so as to produce yarn guides, hooks or
eyes and having bent or curved ends or parts which run in an internal groove turned
or formed in a ring substantially as set forth and indicated.
Thirdly a traveller having yarn guides or eyes and suitably formed to be
sprung into position within a ring formed with an internal groove in which the
two ends of the traveller run substantially as set forth and indicated.
And lastly the groove in the lower end of the bolster in connection with a
suitably formed whirl running close to the bolster end substantially as and for the
purpose set forth and indicated.
In witness whereof, We the said George Perkins, George Wimpenny and
Joseph Hampson Evans have hereunto set our hands and seals this
fourteenth day of December in the year of our Lord one thousand eight
hundred and eighty-two
