IMPROVEMENTS IN APPARATUS FOR SPINNING AND TWISTING FIBRES
Year: 1884

page_text: PROVISIONAL SPECIFICATION.
We THOMAS SPENCE TETLEY, Salesman and THOMAS PICKLES Mill Manager
and ALLAN COCKROFT, Overlooker all of Holmfield Mills near Halifax in the
County of York do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN APPARATUS FOR SPINNING AND TWISTING FIBRES " to be as
follows:-
The object of our Invention is to construct the wharles and arrange the bands on
cap frames, so that the wharles are much lighter, being less in bulk, they can also
be driven by comparatively slack bands, which thereby enable us to work the
frames with a longer traverse, minimizing the possibility of slack twist.
We construct our wharles without or almost without any bottom flange, so as
to greatly lighten them, the necks are reduced in diameter, the bands are passed
twice round the necks of the wharles to prevent the two laps from rubbing against
each other, the top lap runs in a slight hollow below the flange of the wharle;
sufficiently below it, we form a second hollow or groove in which the lower lap
runs, just clearing the top lap and preventing rubbing or friction and wearing of
the bands, by this arrangement less power is required, the necks of the wharle's
will do less in diameter so giving a greater speed when driven off the ordinary size
of cylinder, the above arrangements can be applied to existing cap frames, the old
wharles being turned down to come in for one side of the frames.
COMPLETE SPECIFICATION.
We THOMAS SPENCE TETLEY Salesman THOMAS PICKLES Mill Manager and
ALLAN COCKROFT Overlooker all of Holmfield Mills near Halifax in the County
of York, do hereby declare the nature of our said Invention for "IMPROVEMENTS
IN APPARATUS FOR SPINNING AND TWISTING FIBRES" and in what manner the
same is to be performed, to be particularly described and ascertained in and by the
following statement :—
The object of our Invention is to construct the wharles and arrange the bands
on cap, ring, fly and other frames, or mules for spinning and twisting fibres, so
that the bands may be run without it being necessary to have them always tight

page_text: as at present, and so taking less driving power, and causing less friction, wear and
tear, and vibration of frame, also allowing the band to work a much longer
traverse, than at present, owing to tho bands being slack, there will be much less
wear and tear of bands.
We make our wharles on spindles or tubes, with a double groove, in which the
bands run, passing twice round the cylinder, the grooves preventing the two laps,
from rubbing together; in case of a very long traverse, the division between the
grooves is made sufficiently largo to prevent the bands slipping into one groove.
The above improvements can be applied to existing frames, roving, flyer, mules
ring spinning and twisting frames, in many cases the old wharles may be turned
down, and made to come in for the oxisting frame,
DESCRIPTION OF DRAWINGS.
Fig. 1 shews end elevation of wharle and cylinder.
Fig. 2 is a plan of Fig. 1 (wharle in section).
A is the wharle with two grooves B, and C, the band D, is doubled and passes
round each groove of the wharle, and so prevents the bands from rubbing each
other, the band passing twice round the cylinder E, as the band goes round tho
wharle twice, it gives double driving power and so enables the band to be much
slacker than at present, and so minimizes the possibility of slack twist, the tubes
and spindles running much steadier, less power is required; the above construction
of wharle and arrangement of driving can be applied to existing spinning and
twisting frames, mules, and ring spinning frames; in cap frames by putting on new
tubes, and in fly, mule or ring spinning by putting another wharle either above or
below the present one, so as to make a double groove.
Having now particularly described and ascertained the nature of our Invention,
and in what manner the same is to be performed we declare that what we
claim is:-
The combination (on tubes and spindles for spinning and twisting fibres,) of a
double grooved wharle, with one band passing twice round the cylinder and
around each groove of the wharle in the manner and for the purposes as shewn
and described.
