Year: 1880

page_text: LETTERS PATENT to John Pearson, of Golcar, near Huddersfield, in the County
of York, Manufacturer, for an Invention of "IMPROVEMENTS IN APPARATUS
FOR SPINNING, DRAWING, AND TWISTING FIBRES."
PROVISIONAL SPECIFICATION left by the said John Pearson at the Office
of the Commissioners of Patents on the 29th January 1880.
"
JOHN PEARSON, of Golcar, near Huddersfield, in the County of York, Manu-
facturer. IMPROVEMENTS IN APPARATUS FOR SPINNING, DRAWING, AND TWISTING
FIBRES."
This Invention relates to improvements in spinning, drawing, and twisting fibres,
and is applicable to mules; and by the same a great saving in time, labour, and
cost of machinery is effected, as well as a softer and nicer handling yarn being
produced.
The Invention is constructed as follows:-I attach to an ordinary spinning mule
two sets of bobbins and rollers, the same being carried in extra stands or brackets,
and connected and driven by extra gear wheels and pinions; one set of bobbins,
may carry one color of roving, another set another color. The rovings from both
sets of bobbins pass to and between the ordinary front rollers and are both spun
and twisted at the same time and in the same machine, thus dispensing with the
twisting frames and half of the mule, as well as producing a nicer handling and
softer spun yarn than when done separately in the several machines.
Or several sets of bobbins may be used to one or more rollers of sufficient
diameter, as convenient.

JOHN PEARSON, of Golcar, near Huddersfield, in the County of York, Manu-
facturer. "IMPROVEMENTS IN APPARATUS FOR SPINNING, DRAWING, AND TWISTING
FIBRES."
This Invention relates to improvements in spinning, drawing, and twisting fibres
(applicable to mules), by means of which a great saving is effected in time, labour,
and cost of machinery, as well as a softer and nicer handling yarn being produced.
This Invention is constructed as follows:-I attach to an ordinary spinning mule
an extra set of bobbins and rollers, the same being carried in extra stands or
brackets, and connected and driven by gear wheels and pinions; one set of bobbins
carry one color of roving, another set another color. The rovings on the bobbins are
brought direct from the condenser, pass to and between the ordinary front rollers,
and are both spun, drawn, and twisted at the same time in the same machine; they
are then ready for the loom, thus dispensing with the twisting frames and half the
mule, as well as producing a nicer bandling and softer spun yarn than when done
separately in the several machines. Or several sets of bobbins may be used to one
or more lines of rollers of sufficient diameter, as convenient.
Such being the nature and object of this my said Invention, in order that the
same may be fully understood, I have hereunto annexed one Sheet of Drawings
illustrative thereof, and have marked the same with Figures and letters of reference.
DESCRIPTION OF DRAWINGS.
Figure 1 shows an end elevation of my arrangement with rollers, bobbins, and
gearing for same.
Figure 2 is a plan view of Fig. 1.
A is extra line of bobbins; B, ordinary line of bobbins; C, C, are the rollers
carried in brackets or stands D, D, and connected and driven by gear wheels E, F, G;
the wheels H and J connecting front rollers K, K; the broken line from bobbin A
representing one color of roving, and the full line from bobbin B representing
another; both rovings passing to and between the front rollers K, K, are spun,
drawn, and twisted, as described; the speed of the rollers may be varied by altering
the change gear wheels.
Having thus fully described the nature and particulars of this my said Invention,
I would have it understood that I claim,-
The application and arrangement for spinning, drawing, and twisting at the
same time on the same frame, such as described and illustrated.
In witness whereof, I, the said John 'Pearson, have hereunto set my hand
and seal, this Twenty third day of July, in the year of our Lord One
thousand eight hundred and eighty.
