We HUGH STEVENSON, of 71 Silver Street, Portland Street, Box Manufacturer,
JOHN WEBB, of 112 Grosvenor Street, All Saints, Manufacturer, and SAM HALLAM,
of 29 Clitheroe Street, Slade Lane, Longsight, Engineer, all in Manchester in the
County of Lancaster do hereby declare the nature of said Invention for IMPROVEMENTS
IN PREPARING, SPINNING, DOUBLING, AND TWISTING, COTTON AND OTHER FIBRE AND IN
THE MACHINERY THEREFOR, to be as follows:-
In applying our Invention to a spinning frame we use the ordinary drawing rollers
and a revolving sleeve or tube supported by a bolster in the spindle rail and driven by
a wharve on the outer part of the sleeve on the upper part of the sleeve is a hollow
cup or ferrule which may have a slit or holes, or a wire or other device fixed across
its opening near the top to the lower part of the sleeve below the spindle rail is
secured a Hyer the legs of which may be connected together by a light metal ring or
rings to guide the yarn on to the bobbin and if desired to form a bearing for the flyer
on the winding spindle; the winding on spindle rests in a footstep in the lifting rail
and is supported above by the usual bolster ; or the spindle may be supported by one
rail only.
The rovings to be spun pass through the drawing rollers as usual and then to the
revolving sleeve, either through the slit or holes or over the wire or other device or
direct into the hollow revolving sleeve by which they are spun or partially spun, the
yarn or roving is then given one or more turns round the leg of the flyer and thence
under the ring on the flyer to the spindle where it is wound on to a tube or bobbin, or
on to the bare spindle as desired.
The above improvements in spinning machinery could be applied to ring and
traveller frames by dispensing with the flyer and prolonging the revolving sleeve
below the spindle rail so that the sleeve forms a spindle, the roving is drawn entirely
through the hollow spindle and passes upward to the ring and traveller carried as
usual by a lifting rail and the yarn is wound on to the bare spindle or a tube.

page_text: The revolving sleeve is or may be driven by a band from the usual tin roller but
the winding on spindle is driven from a special tin drum at the varying speeds
necessary to compensate for the changing size of the cop or bobbin and for the
numbers of yarn to be spun. A method of effecting this is by the use of expanding
pulleys one mounted on the main driving shaft of the machine which drives a second
expanding pulley mounted on the supplementary iin drum shaft for giving motion to
the winding on spindles these pulleys are changed in diameter and driven by
clutches sliding on their respective shaffs both being moved simultaneously by a lever
connected with the usual slaper cam on the heart shaft.
When the foot of the spindle is supported in a lifting rail we propose to connect the
automatic mechanism for stopping the machine when the cops or bobbins are full, to
the lifting rail so as to lower it below its working position and thus the cops or
bobbins are brought into contact with the bolster and lifted slightly on the spindles
sufficiently to enable them to be readily removed by the doffers or doffing mechanism.
Our improvements may be applied to roving spinning doubling and twisting.
COMPLETE SPECIFICATION.
Improvements in Preparing, Spinning, Doubling, and Twisting
Cotton and other Fibre, and in the Machinery therefor.
We HUGH STEVENSON, of 71 Silver Street, Portland Street, Box Manufacturer,
JOHN WEBB, of 112 Grosvenor Street, All Saints, Manufacturer, and SAM HALLAM,
of 29 Clitheroe Street, Slade Lane, Longsight, Engineer, all in Manchester, in the
County of Lancaster, do hereby declare the nature of said Invention for IMPROVEMENTS
IN PREPARING, SPINNING, DOUBLING AND TWISTING COTTON AND OTHER FIBRE AND IN
THE MACHINERY THEREFOR, and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement :-
Our invention relates to improvements in preparing, spinning doubling and twisting
cotton and other fibre and in the machinery therefor and consists chiefly in certain
novel applications of and combinations with a spinning device substantially the same
device as that for which we obtained Letters Patent No. 13440 on the 6th November
1885.
The invention farther consists in an arrangement of mechanism for driving the
winding on spindles when a flyer is employed as hereinafter described at the varying
speeds required.
And in order that our Invention may be fully understood and readily carried into
effect we will describe the accompanying six Sheets of Drawings reference being had
to the figures and letters marked thereon.
Figure 1 is a sectional elevation illustrating the mode of applying a flyer to our
patent spinning device.

page_text: Figure 2 is a view illustrating the mode of applying a ring and traveller to our
patent spinning device.
Figure 3 shows a modification of the ring and traveller arrangement. In Figure 2
the winding on spindle is shown made in one piece with the spinning device but in this
case a separate winding on spindle is employed.
Figure 4 is an end view of the mechanism which we employ to drive the winding
on spindles at varying speeds when a flyer is employed as in Figure 1.
Similar letters refer to similar parts throughout the several views.
For the sake of clearness we have omitted in Figures 1, 2 and 3 those parts of the
machinery which are not necessary for the proper explanation of our Invention.
Referring first to Figure 1-Our spinning device consists as described in the
Specification to the aforesaid Patent of the hollow sleeve or tube a and the wire a'
the spinner being fitted in a spindle rail and receiving its motion by means of
a wharve a driven by a band from a tin drum; on the lower part of the central
tube of the spinner « we secure a flyer e the legs of which are strengthened by a light,
metal ring and a collar The winding on spindle d passes through the collar
and is supported in a bolster el secured to a stationary spindle rail e. The lower end
of the spindled rests in a footstep" carried by a lifting rail and motion is com-
municated to the spindled through the wharve d' by a band on a supplementary tin
drum driven at varying speeds, as hereinafter described with reference to Figure 4 or
in other convenient manner.
The roving passes from the usual drawing rollers (not shown) and preferably
through a guide eye or over a guide pulley to the wire at the roving is wrapped say
once round the wire and then passes down the central tube of the spinner a, is taken
one or more turns round one of the legs of the flyers and under the ring to the
spindle d where it is wound either on to a tube or hobbin or on to the bare spindle as
preferred.
The twist is entirely put into the roving or yarn by the action of the revolving
spinner and the winding on is effected by the action of the flyer in conjunction with
the varying speeds given to the spindle d.
Referring to Figure 2.-Instead of a flyer as in the previous arrangement we here
show a ring and traveller g supported in the lifting rail and instead of the
independent winding on spindle d we prolong the central hollow spindle or tube of the
spinner a.
The roving is carried down this central tube and then upward to the traveller by
which it is guided on to the spindle or to a tube or bobbin thereon, the whole of the
twist being put into the roving or yarn by the action of the wire a'.
A modification of this arrangement is shown in Figure 3 wherein an independent
winding on spindle d is employed as in Figure 1 but this spindle instead of being
carried in a lifting rail is supported in a stationary rail the ring and traveller
being carried in the lifting rail * as in Figure 2. The spinner a and spindle d are in
this case both driven at constant speeds by any convenient means.
Referring now to Figure we illustrate herein one arrangement of mechanism for
imparting the varying speeds required to the winding on spindles & shown in
Figure 1.
In this arrangement we employ two tin drums i for driving the spinners a one
for each side of the frame and a single tin drum j for driving the winding on spindles d
at the varying speeds necessary to compensate for the changing size of the cops or
bobbins and for the numbers of yarn to be spun.
On the shaft of one of the tin drums is mounted an expanding pulley which is
connected by a band k to a second expanding pulley secured on the shaft of the
supplementary tin drum. These pulleys are expanded and contracted in diameter as
required by the action of two clutches connected by a vertical shaft m to a bowl on a
lever held in contact with and operated by the shaper cam on the heart shaft.
Although we have only shown and described our Invention as applied to a spinning
frame, it is obvious that it is equally applicable to preparing doubling and twisting
machinery.

page_text: Having now particularly described and ascertained the nature of our said Invention
and in what manner the same is to be performed we declare that what we claim is
1. The combination with the spinner a, of a flyer and a winding on spindle driven
at varying speeds as required substantially as herein described and as illustrated by
Figure 1.
2. The combination with the spinner a having a hollow winding on spindle formed
with or secured to it, of a ring and traveller substantially as herein described with
reference to Figure 2.
3. The combination with the spinner a of a ring and traveller and an independent
winding on spindle substantially as herein described with reference to Figure 3.
4. The combination with the arrangement illustrated by Figure 1 of expanding
pulleys operated by clutches or equivalents from the heart shaft for the purpose of
imparting varying speeds to the winding on spindles substantially as herein set forth.
