COMPLETE SPECIFICATION.
I WILLIAM EDWIN HEYS of 34 Blackfriars Street Salford in the County of
Lancaster Mechanical Engineer do hereby declare the nature of my Invention
for IMPROVEMENTS IN MACHINERY OR APPARATUS EMPLOYED IN SPINNING
DOUBLING TWISTING OR WINDING COTTON WOOL SILK OR OTHER FIBROUS
MATERIALS and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
These improvements relate to machinery or apparatus employed in spinning
doubling winding or twisting cotton wool silk and other fibrous material and
consist in applying thereto an apparatus or arrangement for regulating the tension
of the bands or cords which drive the spindles of such machinery.
It is found difficult by any means at present in general use to secure an uniform
tension for these bands or cords and in the attempt to secure this uniformity the
bands or cords are strained and consequently stress is put upon the spindles and
their bearings.
By these improvements comparatively slack bands or cords are used and the
amount of wear and tear are greatly reduced while the consequent uniformity
of motion results in the production of a more even yarn cop or bobbin.
And in order that this Invention may be more readily understood and carried
into practical effect I have hereunto appended a Sheet of Drawings the Figures
thereon being marked with letters of reference similar letters denoting similar parts
in each of the Figures.
Fig. 1 is a sectional elevation and Fig. 2 is a plan of a portion of a machine
having my improvements applied thereto.
Between the "tin cylinder "C" of the machine and the spindles I fix two rods
or shafts E E¹ the ends of which may be attached to the frame sides or to brackets
fixed upon the frame sides or in any suitable manner so that the rods or shafts are
enabled to maintain positions parallel to the tin cylinder C. Upon the rods or

page_text: shafts E E¹ I mount a number of arms B or levers A each of which carries at its
outer end a small grooved pulley whirl or wharve G. The arms A or levers B are
free to move or swing upon the rods E E' and the wharves G G are free to rotate
in their bearings or upon their spindles or axes. An arm or lever is provided for
cach spindle. On one side of the machine or where the bands or cords pass or
drive from the top of the tin cylinder C to the spindles the simple weighted arms
or levers B are employed the weight of which coming upon the cords or bands
through the wharves G put sufficient tension upon the cords or bands to enable
them to drive the spindle or bobbin without slip. On the opposite side of the
machine or where the bands or cords run from the bottom of the tin cylinder to
the spindles the counterweighted levers A are employed and the tension is put
upon the cords or bands from below through the action of the counterweights F.
In either case the weight or tension is exerted upon the band or cord through the
freely rotating wharve G and upon that portion of the band or cord. which is
passing towards the spindles. By this arrangement the "going on
band or cord is directed in a straight or approximately straight-line to the spindle
wharve D and the risk of the cord slipping or coming off that wharve is reduced.
It will be understood as hereinbefore referred to that the bands or cords are put
in position slack so that all the required tension may be put upon them by means
_of_the_levers or arins A-or-B-and-the-wharves G G.
33 part of the
Where the spindle wharves-D-have-to-move upwards and downwards a little
more slack may be left in the bands or cords so as to permit the-alternate-
lengthening and shortening of the distance between the tin cylinder and the
wharves D without putting any direct stress upon the bands.
In the accompanying Drawings I have illustrated my improvements as applied
to a machine-or-apparatus-having-one-tin-cylinder-only-but the same may be
applied in a similar manner to machines or apparatus-having-two-cylinders.
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,
In machinery or apparatus employed in spinning doubling twisting or winding
cotton wool silk or other fibrous materials, regulating the tension of the bands or
cords which drive the spindles or bobbins by means of weighted or counterweighted
arms or levers A or B and the whirls, or wharves G G substantially as hereinbefore
set forth and described and as illustrated on the accompanying Sheet of Drawings.
