IMPROVEMENTS IN "MULE-THROSTLE" SPINNING AND DOUBLING MACHINERY
Year: 1882

page_text: LETTERS PATENT to William Lancaster, of Accrington, in the County of
Lancaster, Machine Maker, and Edward Slater, of Burnley, in the County
of Lancaster, for an Invention of "IMPROVEMENTS IN "MULE-THROSTLE"
SPINNING AND DOUBLING MACHINERY,"
PROVISIONAL SPECIFICATION left by the said William Lancaster and
Edward Slater at the Office of the Commissioners of Patents on the
7th September. 1882.
WILLIAM LANCASTER, of Accrington, in the County of Lancaster, Machine
Maker, and EDWARD SLATER, of Burnley in the County of Lancaster, "IMPROVE-
MENTS IN "MULE THROSTLE" SPINNING AND DOUBLING MACHINERY"
The first part of this invention relates to the novel employment of plates, cups,
or boxes, instead of the ordinary rings, on which plates, cups, or boxes, we place
our fork-shaped dragwire shown and described below and for which fork-shaped
dragwire, letters patent were granted to William Lancaster and Edward Slater
dated the eighth day of September, One thousand eighty hundred and eighty one.
These plates, cups, or boxes, may be made either wholly or partially of steel,
iron, porcelain, glass, wood, or other material. They may also be made in parts
and may have rings fitted inside, on the top, or underneath them, either fast or
loose.
The so called fork shaped drag wires mentioned above may have projections at
one or both ends, which can be made to serve the three fold purpose of conducting
the yarn from the rollers, guiding it to the winding side of the spindle, and holding
the so called "drag wires" in their positions. These so called drag wires can be made
in many shapes some of which are shown in our drawings. These so called drag
wires can if required be covered either wholly or partially by an antifrictional
substance or appliance.
The next part of this invention relates to the use of wheels, or pulleys made
either wholly or partially of flexible material for the purpose of giving motion to
the first moving parts of these machines.
This invention is an improvement on Patent N° 3896, dated the eighth day of
September 1881, as before said.

by the said William Lancaster and Edward Slater in the Great Seal Patent
Office on the 7th March 1883.
WILLIAM LANCASTER of Accrington, in the County of Lancaster, Machine
Maker, and EDWARD SLATER, of Burnley, in the County of Lancaster "IMPROVE
MENTS IN MULE-THROSTLE' SPINNING AND DOUBLING MACHINERY "
This Invention relates to improvements in mule-throstle spinning and doubling
machinery for spinning and doubling yarns of all fibrous material and forming the
same into cops or bobbins.
The first part of this invention relates to the novel employment of Plates, or
dished out washers as shown in Figures 1, 2, 3 and 4 of the drawings, on which
plates or dished out washers we place our so called fork-shaped dragwire (shown
Figures 7, 8 and 9) for which Letters Patent have been granted to us bearing date
the 8th day of September 1881 and numbered 3896, and which plates, or dished
out washers may be used in lieu of the ordinary Rings now in use on Ring Spinning
and Doubling machinery.
These plates may be made either wholly or partially of steel, iron, porcelain,
glass, wood, or other suitable material, and may have Rings fitted inside, outside,
on the top or underneath them, either fast or loose, and may be made without
grooves.
The said plates as they may be constructed in combined materials are shown at
Figures 5 and 6.
The ordinary travellers can be applied to the said plates or dished out washers
as shown in Figure 10 at E and in Figure 11 at F
This Invention also relates to the application of the so called fork-shaped drag
wire, with or without projections or bends, to the plates or dished out washers
shown at the Figures 1, 2, 3, 4 and 5, and which fork-shaped drag wires can be
made to serve the four-fold purpose of conducting the yarn from the rollers, of
guiding it to the winding side of the spindle, of holding the so called drag wires
in their working position, and also of the further purpose of causing the outline
of yarn to act as a fulcrum for the drag wire when it is working away from the
spindle. The projections or bends on these so called fork-shaped drag wires may
serve to regulate the tension or drag on the yarn between the delivery rollers
and the spindles or cops, in order to wind a hard cop and still spin a soft yarn,
when required. These so called drag wires can be made in many shapes, a few
of which are shown in Figures 7, 8 and 9 of the Drawings.
The opening formed by the arms or forks of these drag wires dispenses with
the grooving of the Rings and enables us to use plates, or dished out washers as
shown in Figures 1, 2, 3 and 4, in lieu of grooved Rings as at present used.
These so called fork-shaped drag wires can, if required, be covered wholly or
partially with an anti-frictional substance or appliance.
The Figures 1 at A, 2 at B, 3 at C, and 4 at D, show two of these so called
fork-shaped drag wires in working position.
Having thus described and ascertained the nature of our said Invention and
in what manner the same is or may be performed, we wish it to be understood
that we do not limit ourselves to the precise details given, as the same may be
varied and modified without departing from the principle thereof, and that what
We Claim as secured to us by the herein before in part recited Letters Patent is :--
In Spinning and Doubling machinery :-
Firstly The use of plates or dished out washers substantially as hereinbefore
described and shown on the accompanying Sheet of Drawings at Figures 1 to 6
inclusive.

page_text: Secondly-The use of plates forming Rings without grooves substantially as
hereinbefore described and shown on the accompanying Sheet of Drawings Figures
1 to 6 inclusive.
Thirdly The application of these so called fork-shaped drag wires to our
plates or dished out washers as shown at A Figure 1 and at C Figure 3, and also
in Figures 7, 8 and 9 of the Drawing; and as herein before described; and further
the application of the ordinary traveller to our plates or dished out washers as
shown in Figures 10 (at E) and 11 (at F) as herein before described.
In Witness whereof I the said William Lancaster, for myself and on behalf
of my Co-Patentee, have hereunto set my hand and seal this fifth day
of March in the year of Our Lord One thousand Eight hundred and Eighty
three
