page_text: We SAMUEL NEWTON and THOMAS NEWTON of Barker Street Strangeways
Manchester in the County of Lancaster Machinists do hereby declare the nature of
this Invention to be as follows:-
Our Invention relates principally to the throstles used in the spinning of cotton
or other textile materials but is also applicable wholly or in part to roving frames
or other frames used in the preparation of cotton or fibrous material. The
principal object of our Invention has been to produce mule cops upon the throstle
frame or otherwise to produce upon such frame cops which can be used for the
same purposes as mule cops. To this end we employ a positively driven ring to
impart the twist; we impart a varying speed to the spindle for winding on and
we impart a quick return movement to the copping rail so as to produce the
Crossing which gives coherence to the cops. The spinning ring slides up and down
upon the limbs of a flyer or upon a suitable cage or part, which receives a revolving
motion from the tin roller. The said ring is grooved exteriorly or is otherwise
adapted to engage with a carrier which is secured to the copping rail so that as
the said rail rises and falls the ring is moved up and down. In our experiments we
have used fingers entering a groove in the ring but we may greatly vary this part
of our invention as for example we may employ frictional drivers to impart motion
to the rings. The winding on motion is imparted by a second tin roller which
receives motion from the ordinary tin roller shaft or from a suitable shaft in the
frame. Upon the winding on tin roller shaft is mounted to slide a cone which is
slotted to clear arms which project from the shaft and which keep the band in
position. As the winding on proceeds the cone is slid upon the shaft the cone
being proportioned to increase the speed of the tin roller as the copping rail rises so
that the cop is built up with uniform tension. The said cone is shifted by means
of a fork which is carried by a sliding bar and this bar receives motion from a
revolving cam which acts upon a bowl or part which is suitably connected with
the bar so that the traversing of the bar is effected. The cam is so forined as that
when the copping rail has reached the top of its lift the said sliding bar is per-
mitted to make a quick return movement the copping rail also making a quick
lowering movement whereby an effect similar to the backing off of the mule is

page_text: produced. The copping rail is controlled in its movements by a double set of
inclines the one set being carried by the aforesaid sliding bar and acting upon the
parts which sustain the rail so that the said rail moves in unison with the said
bar. The second set of inclines sustains the said sliding bar and by gradually
raising or lowering the bar according as the parts may be arranged causes the cop
to be built up in successive conical layers as is usual. The said second set of
inclines is acted upon by a screw which is alightly turned at each traverse of the
said sliding bar by means of a ratchet and pawl the pawl lever being acted upon by
an incline carried by the said bar. The cam which acts upon the said sliding bar
is shaped to have a variable effect on the bar according as one part or another is in
contact with the bowl the cam being shifted in the direction of its axis or the
said bowl being shifted in the same direction during the building of the cop bottom
until the regular building up of the cop commences. The inclines which act upon
the copping rail may be carried by a special bar or a cam may be used instead of
such inclines and other modifications may be made in the copping motion especially
in the cases wherein our invention is applied to roving frames or to other prepara-
tion machinery. We prefer to work the frames in pairs the cop building motions
being arranged in a headstock between the two frames in a pair in a similar
manner to the ordinary mule. As the spinning and winding on operations are
continuous there is not the same loss of time as in the mule so that a larger
quantity of yarn can be produced in a given time on our improved frame.

page_text: and Preparation of Textile Materials.
We SAMUEL NEWTON and THOMAS NEWTON of Barker Street Strangeways,
Manchester in the County of Lancaster, Machinists do hereby declare the nature
of this invention and in what manner the same is to be performed to be particu-
larly described and ascertained in and by the following statement and accompanying
drawings:—
'
Our Invention relates principally to the throstles used in the spininng of cotton
or other textile materials but is also applicable wholly or in part to roving frames
or other frames used in the preparation of cotton or fibrous material. The principal
object of our invention has been to produce mule cops upon the throstle frame
or otherwise to produce upon such frame cops which can be used for the
same purposes as mule cops. To this end we employ positively driven rings to
impart the twist; we impart a varying speed to the spindles for winding on and
we impart a quick return movement to the copping rail so as to produce the
crossing which gives coherence to the cops.
Our Invention will be best understood when the same is described with reference
to the accompanying sheet of drawings which are made to a scale of about one
and a half inches to the foot. In the said drawings Fig. 1. is a front elevation of
the central portion of a spinning frame constructed in accordance with our
invention. Fig. 2. is a vertical cross section on the line A. and Fig. 3. a vertical
cross section on the line B. In the said Figs. a. a. are two headstock standards
through which pass the shafts of upper and lower tin rollers b. c. The lower tin
roller drives the spindles d. and the upper tin roller the spinning rings e. these
parts appearing on a larger scale in Figs. 4 and 5. Each ringe is formed with
two inner grooves which are occupied by the limbs of a flyer f. the arrangement
being such as that the ring is compelled to revolve with the flyer but is free to be.
carried up and down sliding upon the limbs of the flyer. The flyer is formed with
a hollow neck which works in a bearing in a fixed rail g. a warve h. upon the said
neck receiving the driving band whereby a revolving motion is imparted from the
upper tin roller. In the example the ring e. is formed with a circumferential
groove into which enter the fingers of a carrier i, which is secured to the copping
rail j. so that as the said rail rises and falls the ring is moved up and down
sliding upon the limbs of the flyer as aforesaid. The spindles d. are mounted in
footsteps carried by the fixed spindle rail k. and each spindle extends upwards
through the neck of the flyer and the centre of the ring. The yarn proceeding
from the drawing rollers passes through a curl or guide upon the ring and is
twisted by the revolutions of the ring and is also wound upon the spindle the
building up of a cop upon the spindle being governed by the concerted revolving
movements of the spindle and upward and downward movements of the copping
rail. The lower or winding on roller c. receives motion from the shaft of the
upper or spinning roller shaft b. by means of a band Z. which passes around carrier
•

pullies m. m¹ the latter being mounted in a loaded swivel frame n. whereby an
uniform tension of the band is maintained. Upon the shaft of the roller c. is
mounted a cone o. which. is fitted to slide upon a fast key. The said cone is slotted
to clear arms p. which carry rings p¹ and which project from the shaft and are
fixed thereon these arms and rings serving to keep the band Z. in position so that
the cone can be slid to and fro without dragging the band out of the direct line.
As the winding on proceeds the cone is slid upon the shaft by means of a fork g.
shown in Fig. 6. which fork is fixed to a sliding bar r. which receives motion from a
cam not shown in the drawings and which transmits the said motion through a
regulating lever 8. The cone is suitably proportioned to increase the speed of the
winding on roller as the copping rail rises so that the cop is built up with uniform
tension. The lever 8. is provided with a screw which works in a nut in a part which
is connected by a link t: with the bar r. and which is also jointed to the link u
upon which the cam acts. A ratchet wheel v. upon the upper end of the screw engages
with a finger or pawl which is hinged to a part carried by the framing so that as
the lever vibrates to and fro the screw is rotated. At the commencement of the
building up of the cop bottom the nut is near the lower or inner end of the lever
and as a consequence a short traverse is imparted to the bar r. and the band is
only moved to and fro on the smaller end of the cone but as the building up
proceeds the nut is slid toward the outer end of the lever whereby the length of
traverse of the bar r. is increased. When the bar is moved endwise the fork slides
the cone upon the roller shaft and as the band is kept from moving with the cone
a part of the cone of a larger or smaller diameter is brought into position to be
acted upon by the band according as the cone is slid in one direction or the other.
The parts are so arranged as that during the rising of the copping rail the cone is
moved in the direction from left to right so that the speed of the spindles is
increased and on the contrary when the copping rail is being lowered the cone
is moved from right to left so as to decrease the speed of the spindles. A stud
tipon the bar r. enters a slot in a part w which is formed or fixed upon a second
bar w. which is formed with an incline. A bowl upon a vertical rack x. rests
upon the said incline and the said rack gears with a pinion which is fixed upon a
shaft y. which communicates the rising and falling movements to the copping rail
in the ordinary manner. The aforesaid cam which acts upon the link u. is suitably
shaped to impart through the described media a slow rise to the copping rail
corresponding to the winding on movement of the mule faller and a quick fall
corresponding to the movement made by the mule faller when the spindles "back
off" so that the cops become built up in a similar manner to the cops of ordinary
mule twist. The winding on is advanced so as to build up the cops by means of
the inclines z. which support the bar w. Upon the said bar are studs or bowls
which rest upon the said inclines vertical guides a¹ preventing the said studs from
sliding down. The bar or part carrying the said inclines is mounted to slide end wise
and is acted upon by a screw which is provided at the outer end with a ratchet
wheel b, seen also in the detached view Fig. 7. One end of the bar w, is prolonged
and is shaped to act upon a lever c¹ which carries a pawl which engages with the
said ratchet wheel. During each movement of the bar w. from left to right the
said lever is depressed and the screw is thereby rotated the other end of the lever
being loaded or acted upon to give the return movement to the lever.
Each slight
fotatory movement of the said screw has the effect of slightly moving the inclines
toward the left hand-in the direction of the arrow-whereby the bar w. is lowered
and as a consequence the points of highest and lowest positions of the copping rail
are raised to a suitable degree and the cop becomes built up. The headstock is
supposed to be in the centre of a frame and to have spindles arranged in rows
extending right and left. The rings & may be otherwise mounted than in or upon
the carriers i. as for example each ring might be kept in place by means of three
wheels or pullies and be driven by one of the three in which case the flyer f. could
be dispensed with.
