We, SAM, HALLam, Engineer, of 13 Clitheroe Street, Slade Lane, Longsight,
Manchester and EDWARD TILSTON, Draughtsman of 37 Clitheroe Street, Slade Lane,
Longsight, Manchester, do hereby declare the nature of this invention to be as
follows:-
With the object of obviating or mitigating the increased drag that occurs in Ring
Spinning, Throstle, or other Frames when winding upon small diameters, or upon
the bare spindle, we employ a central winding spindle, driven, in the ordinary.way,
by a band from lower druin or drums, and an outer inverted Cup, flyer or other
suitable device, so constructed, as to take a ring of any suitable form or diameter. to
receive traveller, at its upper end or lip.
This cup, flyer, or device being rotated by a band from an upper rovolving drum
or drums.
The spindle carrying the inverted cup, flyer, or device, is hollow, so as to, allow
is
the passage, through it, of the above mentioned central winding spindle, and pro-
vided with a Wharve, or Whorl to receive band from upper drum or drums; which
drum or drums are driven by band, belt or otherwise, in such a manner, as, that their
speed of rotation, can be varied at will, to suit the character and count of yarn
required to be spun or twisted.
The lower drum or drums are driven at a constant uniform speed as in ordinary
Ring Spinning or Throstle Frames. The central winding spindle is driven by lower
drum or drums, and passes through spindle carrier secured to rail, and has a longi-
tudinal groove or channel of suitable length formed in it, to take key, or pin, or end
of screw attached to Wharve or, Whorl carrier, and has a bearing in, a footstep
secured to a lifting rail, which lifting rail, has an upward an downward movement
given to it by suitable gear as in ordinary Ring Spinning or Throstle Frames.
The Wharve or Whorl carrier enters into and rotates; in a suitable bushed cavity.
formed in spindle holder or carrier.
The power of giving to the upper drum, or drums, a greater, or less, uniform
rotative velocity, enables for each variety and count of yarn, such, a constant.number
of revolutions to be, given to inverted cup, flyer or device carrying Ring that the
movement of the traveller upon it, relatively to the Ring, and therefore, the drag or
pull upon the yarn can be made least or nil when it is being wound on the bare
spindle at.its least diameter.

We SAM. HALLAM of 13 Clitheroe Street, Slade, Lane, Longsight, Manchester, in
the County of Lancaster, Engineer, and EDWARD TILSTON, of, 37 Clitheroe Street,
Slade Lane, Longsight, Manchester aforesaid, Draughtsman, 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, and accom-
panying-drawings:.....
Our Invention relates, to spinning and doubling frames, and has for its object, to

page_text: prevent or lessen the increase of drag which occurs at the times when the yarn is
being wound upon the bare spindle or upon the smaller diameters of the cop or of
the mass of yarn upon the tube or bobbin as the case may be. We mount the ring
upon a cup or ring carrier which receives a revolving motion from a drum which is
driven at a speed which can be varied without effecting the speed of the drum which
drives the spindles so that the retarding effect of the ring upon the traveller may be
lessened or neutralised or even if desirable the ring may out run the traveller.
In order that the nature and object of our Invention may be understood we will
describe the same more fully with reference to the accompanying drawings.
In the said drawings Fig. 1 represents a spindle with its mountings represented
in section and Fig. 2 is a corresponding view of a modification in the construction
and arrangement of some of the parts. In the said Figs. a is the spindle is the
ring-carrier and c is the ring. The ring carrier is driven by means of the whirl d
and the spindle by means of the whirl e.
The ring carrier is in the form of a cylindrical cup having the ring secured to its
upper edge. The said cup is secured to the whirl d which is fixed or formed upon a
sleeve d' which can be lifted out of its bearing: In Fig. 1 the said sleeve revolves
within a tubular spindle driver el which is mounted to revolve in a bolster f which is
secured to the fixed rail g and is formed with an oil cup f¹. The said bolster is
fitted with suitable- linings which are adapted to act as bearings for the spindle
driver and the latter is similarly provided with bearings for the sleeve d¹. The
spindle driver extends downward through the lower end of the bolster and is slotted
to receive two keys h. h which enter key grooves which are cut in the spindle so
that the latter is caused to revolve when the spindle driver is rotated by the action
of a band upon the whirl e.
A nut or collar e upon the lower end of the spindle driver prevents the latter from
being lifted out of its bearings when the sleeve is withdrawn. Lubricant from
the cup has access to the interior of the bolster and of the spindle driver in order to
lubricate the bearings in the same. A tube i fixed in the spindle driver extends
upward above the level of lubricant in the oil cup in order to check the escape of
lubricant. The spindle is steadied by fitting a bearing in the lower end of the
driver e but is free to slide in such bearing. It will be seen that as the spindle
and the ring carrier are driven independently of each other the speed of the latter
may be varied to any desirable extent without interfering with the speed of the
spindle. The modification illustrated by Fig. 2 differs from Fig. 1 principally in
that a tube e fixed inside the spindle driver extends upward within the sleeve d¹ and
the whirld and drives the spindle by means of keys h. h fitted into slots near the
upper end of such tube. In this example the sleeve d¹ revolves upon the tube e³ and
clears a recess bored in the spindle driver and the spindle is guided and steadied by
means of a lining bush e. If preferred the spindle might be made with one or more
flat sides in part of its length and slide in correspondingly shaped bearings so as to
dispense with the necessity for grooving the spindle. The means whereby we drive
the spindle and the ring carrier are indicated in Figs. 3 and 4 in which such parts as
are not necessary to the sufficient illustration of our Invention do not appear. Fig. 3
is a view.on a vertical plane which would cut across the width of the frame. The
row of spindles upon each side of the frame is represented by a.
The spindles are driven by a drum & ordinarily known as the tin roller. Bands
extend from this drum right and left to the whirls e. e whereby the two rows of
spindles receive revolving motion as is usual. The drum is driven in the usual or
in a suitable manner the means for actuating this drum not forming any part of our
invention. The ring carriers are driven by a second drum m by means of bands n
extending right and left to the whirls d. To this second drum we impart a revolving
motion which can be varied in speed to suit the stage of the winding on or cop
building and also to suit, varying counts and qualities of yarn. In practice we
transmit motion from the shaft k¹ upon which the driver k is fixed to the shaft of
the drum m by means of pullies capable of being expanded and contracted but if
preferred cone pullies or other suitable means may be employed.

page_text: Fig. 4 illustrates the arrangements which we have made for driving the second
drum m.
Upon the shaft k¹ is fixed a pulley which is formed in two parts one
part o fixed to the shaft and the other part o¹ fitted to slide upon the shaft. Each
part is formed with inclined fingers the fingers upon one part passing between the
fingers upon the other part so that by sliding o' toward o the diameter of the bevel
groove between the two parts is reduced and on the contrary by separating the two
parts the working diameter is increased. The construction and action of this
variable pulley are in accordance with part of an invention for which Letters Patent
number 4995 of the year 1886 have been granted to one of us the said Sam. Hallam
in conjunction with others. A corresponding pulley is fixed upon the shaft m, and
the two pullies are connected by means of an endless band p which passes over
carrier pullies one of which is seen at q it being supposed that the other pulley
would be exactly behind the pulley 9 and therefore would not appear in the drawing.
These two pullies may revolve loosely upon a shaft or be each mounted upon a
separate stud. We prefer that one or both of the pullies shall be adjustable so that
the slack of the band p may be taken up when desirable. A convenient arrangement
would be to mount one of the pullies in or upon a bracket which would be adjustable
upon the framing.
If preferred such bracket may be prepared to slide in planed guide ways and be
acted upon by a screw. The parts o¹ of the two expanding pullies are fitted to
slide upon their shafts and have such sliding movements controlled by means of two
levers r. s which are forked to engage with grooved bosses on the said parts o¹.
The said levers are mounted upon fulcra at t and are coupled together by means of
a connecting link u.
which is
The upper
end of the lever is connected with a rod or screw shaft
acted upon by means of a hand wheel w in which is formed a nut to suit the screw
thread upon the rod v. By turning this hand wheel in one direction or the other
the lever is caused to rock upon its fulcrum to the right or left in the drawing
according to the direction of rotation of the said hand wheel and as the two levers are
coupled together they move in unison. It will be seen that when the rod is moved
in the direction indicated by the arrow the pulley upon m' will be increased and the
pulley upon will be reduced in working diameter whereby the speed of the ring
carriers will be reduced. Preliminary to the commencement of the winding opera-
tion the speed of the ring carriers may be increased to a suitable degree. As the
cop bottom increases in diameter the band wheel may be operated upon at intervals
or the screw shaft may he acted upon automatically so as to reduce the speed of the
ring carriers. It will be seen that at any time the speed of the rings can be altered
as may be considered desirable.
In practice it may not be necessary in all cases to alter the relative speed of
rotation of the rings after such speed has been regulated to suit a certain quality or
count of yarn. The rings may be of any suitable form and travellers of any ordinary
or suitable description may be used in connection with such rings. It is obvious
that a corresponding effect may be obtained by keeping the speed of the rings
relatively constant and varying the speed of the spindles. To effect such a change in
the arrangements it would be only necessary to drive the roller m positively and to
transmit motion from the shaft m to the shaft k¹. We do not confine ourselves to
the exact details of the spindle mountings nor to the means for varying the speed of
the drum m.
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 spindles actuated in the ordinary or in a suitable manner the cup or part
carrying the ring and mounted to revolve independently of the spindle and the
second drum for driving the said cup in combination with means for varying the
speed of such second drum substantially as and for the purpose set forth and
indicated.

page_text: (2) In ring spinning or doubling frames mounting each ring upon a,ring carrier
which can be revolved on the same axis as the spindle by means of, a special drum
and transmitting motion to such special drum by means which will permit of the
speed of the rings being varied relatively to the speed of the spindles substantially as
set forth.
(3) In ring spinning or doubling frames mounting each ring upon a ring carrier
which can be revolved upon the same axis as the spindle and, driving such ring
carriers and the spindles by means of separate drums in combination with means
for varying the speed of one of the drums substantially and for the purposes set
forth.
(4) The ring carrier & secured to the whirl d and the sleeve mounted to revolve
around the axis of the spindle a independently of such spindle in combination with
the special drum m and with the means for varying the speed of such drum substan-
tially as and for the purpose set forth and indicated.
