page_text: I ROBERT ASHTON of 18 Hart's Head, Pike View, Waterloo, Ashton-under-Lyne,
in the County of Lancaster Engineer do hereby declare the nature of this invention
to be as follows:-
-
My said invention relates to the doubling of yarns in the manufacture of driving
bands for spindles. According to the ordinary method the yarns are drawn from
the cops through a funnel by hand on to the floor or into a receptacle from which
they are conveyed to be twisted together. As the operator has to give attention
not only to the pulling through of the yarns but also to the continuity of the ends,
the full number of yarns necessary to form a band cannot always be doubled
together and it is frequently necessary to double the required quantity of yarn in
separate portions and unite them afterwards. According to my invention the
yarns are drawn mechanically through the funnel and coiled upon a revolving
beam or roller upon which they can be transported to the place where the twisting
is carried on.
In using my invention the full number of yarns can at all times be
doubled simultaneously and together and a single operator can attend to more than
one machine whereby I obtain a considerable economy in labour together with an
improved result. In an apparatus constructed according to my improvements the
cops are arranged as usual on a plank or bank and the required number of ends
are passed through holes in a guide board above the cops and thence over a wire
to the funnel, in passing through which they are brought together or "doubled."
After passing through the funnel the yarns thus "doubled"
are coiled upon a
revolving flanged beam. In order that the coiling may proceed with regularity
I fix the funnel to an arm or bracket which projects from a reciprocating traverser
carried by a shaft in proximity to the beam. The said shaft is hollow and contains
a screw having a right and left hand thread. A block or projection from the
traverser engages with the screw thread and is shunted at the end of each traverse
from the right into the left hand screw or vice versâ as in the case of the well
known Horsfall Grinder, so as to traverse the bracket and funnel backwards and
forwards and thus coil the doubled yarns upon the beam. I may however use
reversing gear or other means to reciprocate the traverser and funnel. When the

page_text: beam has become full it is removed with the doubled yarn to be twisted. Bars may
be arranged to put any desired strain or drag upon the yarns while being doubled.
The beam and traversing screw may be driven from a common driving shaft
having a fast and loose pulley. I place the means for operating the belt fork close
to the beam so that the operator on detecting the breakage of an end or other
defect can immediately stop the machine. The arm or traverser may be hinged
or made capable of being turned back so as to take the funnel out of the way
when removing or replacing the beam which receives the doubled yarns.

Manufacture of Driving Bands for Spindles.
I ROBERT ASHTON of 18 Hart's Head, Pike View, Waterloo, Ashton-under-Lyne
in the County of Lancaster Engineer 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 accompanying
drawings:-
My said Invention relates to the doubling of yarns in the manufacture of
driving bands for spindles. According to the ordinary method the yarns are
drawn from the cops through a funnel by hand on to the floor or into a receptacle
from which they are conveyed to be twisted together. According to my invention
the yarns are drawn mechanically through the funnel and coiled upon a revolving
beam or roller upon which they can be transported to the place where the twisting
is carried on. In using my invention the full number of yarns can at all times be
doubled simultaneously and together and a single operator can attend to more
than one machine whereby I obtain a considerable economy in labour together
with an improved result.
And in order that my said invention may be better understood I will now
proceed more particularly to describe the same with reference to the annexed sheet
of drawings wherein Fig. 1 is an end elevation and Fig. 2 a front elevation of the
apparatus constituting my invention.
The mechanism is mounted between two end frames a secured together by
stays b. The beam upon which the doubled yarns are coiled is marked c. and the
said beam is rotated at the required speed from the driving shaft d. The said
shaft d. receives motion from a band passing around the fast and loose pullies e,

page_text: "
A conical roller J. пxed on the snart a. communicates motion by means of a band g.
to a second conical roller h. and a pulley i. on the shaft of the said second conical
roller h. drives the beam c. In front of the beam c. is situated a funnel j. which
during the working of the machine is reciprocated to and fro in front of the beam
so as to coil the doubled yarn in regular layers upon the revolving beam. The
funnel j. slides backward and forward on a hollow shaft k. which contains a right
and left hand traversing screw engaging with a projection from the boss 1 of the
funnel this traversing arrangement being similar to that used in the well known
Horsfall Grinder and forming no part of my present invention. The traversing
screw is driven from the driving shaft d. by means of a band passing over a
pulley n on the end of the screw. In proximity to the funnel j. I arrange a bar l.
over which the yarns m are drawn from the cops which are arranged as usual on a
plank or bank not shown in the drawings. As shown most clearly at Fig. 2 the
yarns m are drawn from the cops from various directions and converge into the
funnel j. through which they are drawn by the revolving beam and thus become
laid together or "doubled before being coiled on the beam. Bars may be
arranged to put any desired strain or drag upon the yarns on their way to the
funnel. The funnel is preferably hinged to its boss as shown so that it may be
turned out of the way when removing the filled beam and replacing an empty
beam. It will be evident that as the coiling on of the doubled yarn on the beam c.
proceeds, the diameter of the beam will increase, and consequently if the speed of
the beam is maintained the yarns will be coiled on with greater velocity. To
obviate this defect I provide means for diminishing the speed of the beam in
proportion to its increasing diameter. This is effected by the employment of the
two conical rollers f. and h. herein before referred to the belt g. being shifted in the
direction of the arrow as the coiling on proceeds. At the commencement of the
coiling on, the belt g. is at the end of the machine marked A. The funnel j.
traverses to the end of the machine marked B. coiling a layer of doubled yarn on
the beam as it proceeds; the direction of motion of the funnel is then reversed and
it returns, laying on another layer of yarn. At the end of this return stroke the
funnel comes into contact with the upper end of a lever o. pivotted on the stay b¹.
At the lower end of this lever o. is a pawl which gears with a ratchet wheel on
the spindle p. which is supported in bearings q. On the inner end of this spindle p.
is a pitch chain wheel r. and on the same axis is a grooved pulley & around which is
coiled a cord or band which sustains a weight t, the pull of the weight thos
tending constantly to turn the spindle p. and chain wheel r. in the direction of the
arrow. The ratchet and pawl however prevent this rotation of the spindle except
at the times when the lever o. is moved at the end of the to and fro traverse of the
funnel j, this movement of the lever o. permitting the ratchet wheel to revolve to
the extent of one tooth or it might be to the extent of two or more teeth as
desired. A pitch chain or band t. is passed around the chain wheel r. and also
around a chain wheel u at the other end of the machine marked B. The lower
portion of the chain carries a belt fork v. which shifts the belt g. on the cones f.
and h. The consequence of this arrangement of parts is that when the lever o. is
moved by the funnel the chain wheel r. revolves slightly so as to move the belt
fork v. in the direction of the arrow and by thus shifting the belt to reduce the
speed of the cone h and consequently of the beam c. This shifting of the belt and
reduction of the speed of the beam takes place at each alternate traverse of the
funnel j. and thus preserves a sufficiently uniform degree of surface speed of the
coiling on periphery of the beam whereby the yarns are drawn from the cops at
an equal speed from the beginning to the end of the operation. When the beam is
full of doubled yarn it is removed and replaced by an empty beam. The belt fork
can be brought back to its original position by turning the hand wheel w. on the
spindle p. The method of driving the machine may vary from that hereinbefore
described and the to and fro movements of the funnel may be obtained by
reversing means other than a right and left hand screw. By means of this
apparatus the full number of yarns can at all times be doubled simultaneously and

page_text: together and as one operator can attend to more than one machine a considerable
economy in labour is effected as well as an improved result.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed I declare that what
I claim is:
1. The general arrangement, construction and combination of apparatus for
automatically doubling yarns in the manufacture of spindle driving bands sub-
stantially as herein before described and shown.
2. In a yarn doubler of the indicated nature traversing the funnel j. auto-
matically to and fro in front of the beam a. so as to coil the yarn thereon in regular
layers in combination with the means for reducing the speed of the beam as the
coiling on proceeds, substantially as hereinbefore described and shown.
