IMPROVEMENTS IN MACHINES FOR SPINNING AND TWISTING YARN
Year: 1884

page_text: I HENRY HARRIS LAKE, of the firm of Haseltine, Lake, and Co, Patent Agents,
Southampton Buildings, London, in the County of Middlesex, do hereby declare
the nature of said Invention for "IMPROVEMENTS IN MACHINES FOR SPINNING
AND TWISTING YARN" and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement :—
This Invention relates to machines for spinning and twisting yarn. In such
machines it is important that all the spindles shall run at an uniform speed, so as
to produce a product of uniform quality.
In a spinning machine the rolls are driven at a fixed rate of speed and deliver a
certain quantity of sliver; when the driving-band on one or more of the spindles
becomes too slack such spindle or spindles will not exert as much tension on the
sliver as is exerted by the others, and will not put in the proper twist, so that tho
quality of yarn produced will not be uniform.
The object of this Invention is to overcome these difficulties and to so arrange
the spindle-driving bands that the spindles shall run at an uniform rate of speed,
and it consists essentially in the peculiar construction and arrangement of parts,
whereby the spindles of a spinuing or twisting machine shall each be driven by
two or more bands and each of said bands shall in turn pass around two or more
spindles, as hereinafter described.
In spinning and twisting machines as heretofore constructed, the spindles have
been driven in various ways; in the single-driving cylinder machine the spindles
have usually been driven by a separate band which passes around the driving
cylinder and also around the whirl on the spindle. Such machines have also been
driven by passing the band around the driving cylinder and then around the whirls
of two spindles placed on opposite sides of the spinning-frame. In two-cylinder
machines one spindle on each side of the machine is usually driven by a single band
which passes around the cylinders and the whirls of the opposite spindles.
Furthermore a number of spindles have been driven by one band, but in all of
these arrangements each spindle has been driven by one band only; unless when
two bands were used to drive the spindle, and in all of these methods the spindles

page_text: have been liable to variations in speed because the different bands were liable to
adhere to the several whirls more or less closely, thus causing more or less slip.
In accordance with my Invention the bands are passed around the whole, or
more exactly, the whole periphery of the whirl, and such band is connected with
two or more spindles and each spindle is connected with two or more bands; so
that all of the spindles shall be driven at an uniform rate of speed.
In the accompanying Drawing,
Figuro 1 is a view of a section of a driving-cylinder and parts of three spindles
each of which is provided with a three grooved whirl.
Figure 2 is a plan view of the three whirls shown in Figure 1.
Figure 3 is a view of parts of three spindles each being provided with a five
grooved whirl.
Figure 4 is a view of parts of two spindles each being provided with a five
grooved whirl.
Figure 5 is a view of three spindles each provided with a three grooved whirl
connected with a double band so that the three spindles will be connected and
driven at the same speed.
Figure 6 is a view showing three spindles provided each with a four grooved
whirl and connected by double bands.
Figure 7 is a view of parts of four spindles provided each with a two grooved 1
whirl and a driving-band connecting two of the spindles.
A indicates the driving-cylinder; B, B the spindles; C, C the whirls, and D, D
driving-bands. The direction of movement of the bands is indicated by the arrows
and the different bands are distinguished by arrows in plain lines and those
provided with circles.
Referring to the Drawing, it will be seen that in Figures 1 and 2 the band
passes from the cylinder to the whirl of one spindle, thence around the said whirl,
thence around the whirl of the noxt spindle, thence back over the first whirl and
from thence to the cylinder. Therefore each band passes around the whirls of two
'spindles and each spindle is driven by two bands; thus.interlacing all the bands
with all of the spindles. It is obvious that in this method of driving the spindles, as
well also in all of the methods here shown and hereinafter described, the same band
will drive two or more spindles on the opposite sides of the spinning or twisting
machine, one side only being shown in the Drawing.
Referring now to Figure 3; it will be seen, by following the arrows, that the
band from the driving cylinder passes first around the upper groove on the whirl
on one spindle, thence around the second groove of the whirl on the next spindle,
thence around the first whirl in its third groove, thence around the second whirl in
its fourth groove, and, after passing around. the first whirl in its fifth groove, to the
cylinder. But with this five-grooved whirl, the central loop a instead of passing
back to the first whirl, may be carried from the second to the third whirl, and so
the band extends first around the first whirl, then around the second whirl, then
around the third whirl, in its central groove, and then back again to the second
and first whirls, in the same manner to the cylinder thereby driving three whirls
or six, three on each side of the frame, by one band and also driving each spindle
by three bands, each of which compensates for any slip in the other. Thus all of
the spindles must turn at an uniform rate of speed. Referring to Figure 4 it will
be seen that five grooved whirls may be used; in which arrangement the band
leads from the driving-cylinder to the first groove of one whirl, thence to the
second groove of the second whirl, thence to the third groove of the first whirl, and
so on back and forth from one whirl to the other around the proper grooves and
finally returning to the cylinder.
Referring to Figures 5 and 6, it will be seen that in Figure 5 the grooves in the
whirl are wider than usual, and that in Figure 6 the upper and lower grooves are
wider than the two middle grooves and also that two bands are used to drive the
spindles. In Figure 5 the two bands, indicated by the plain arrow and the circled
arrow, extend to the upper groove of the whirl from the driving cylinder, by

page_text: following the plain arrow of the band on the central spindle, it will be seen to
pass partly around the first whirl in its upper groove, thence around the left-hand
whirl in its central groove, from this to the first whirl, surrounding the same in
the lower groove, while at the same time the other band, indicated by the circled
arrow, passes around the first whirl in the upper groove, thence around the central
groove of the whirl on the right hand spindle, thence back again around the first
whirl and with the other band to the driving-cylinder. Thus the two bands drive
the central spindle and the two adjacent spindles; while at the same time the
central spindle is driven by bands from the adjacent spindles.
In Figure 6 the double band is arranged in the same manner, with this difference,
that in place of the central wide groove, two grooves are used.
Figure 7 illustrates a simple arrangement in which each band drives two adjacent
spindles on the same side of the frame; each spindle being driven by two bands
each of which nearly encircles the whirl. Thus a longer bearing is given upon
each whirl for the band and the positive driving of the spindle is ensured even
with a slack band,
The same band may extend to both sides of the spinning machine so as to drive
four spindles, while each spindle is driven by two bands.
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:-
-
First. The combination of a driving-cylinder and a series of driving bands
extending from the cylinder to the spindles, the said bands being so arranged
that each band shall drive two or more spindles, and the latter being each driven
by two or more bands, substantially as, and for the purpose, set forth.
Second. The combination with a driving-cylinder, and a series of spindles
carrying grooved whirls, of a series of bands extending from the cylinder to the
spindles, the said bands being laced from one spindle to another and surrounding,
or partially surrounding, said spindles, each band being arranged to drive two or
moro spindles, and each spindle being driven by two or more bands, substantially
as, and for the purposes, set forth.
