Agent, do hereby declare the nature of the said Invention for "Im-
PROVEMENTS IN MACHINERY FOR PREPARING, SPINNING, AND DOUBLING COTTON
AND OTHER FIBROUS SUBSTANCES," being a communication to me from

motion of any spindle without interfering with the working of the other
spindles.
In performing this Invention the spindles to be driven are supported

friction pulley, made by preference of leather, but any other suitable
substance may be used; this pulley rests upon another friction pulley
made of cast iron or other suitable substance, fixed on a horizontal shaft,
and on this shaft are fixed as many pulleys as there are spindles to be
driven. This horizontal shaft is driven as usual, and corresponds to the
shaft now in use when the spindles are driven by bevel wheels and
pinions. In front of each spindle and supported by studs fixed in the
bolster rails is a flat vertical rod, the lower end of which is bent at right
angles, and passes under the lower end of the spindle; when it is
required to stop a spindle the attendant slightly raises this rod, and
thereby lifts the friction pulley on the spindle out of contact with the
pulley on the horizontal shaft.

stopping each spindle independently of the others.

and vend, within the United Kingdom of Great Britain and Ireland,
the Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS
IN MACHINERY FOR PREPARING, SPINNING, AND DOUBLING COTTON AND OTHER
FIBROUS SUBSTANCES," being a communication to me from abroad by
Eugene Huret, Manufacturer, and Francois Louis Debruyn, Spinner,
both of Paris in the Empire of France, upon the condition (amongst
others) that I, the said Henry Bernoulli Barlow, my executors or
administrators, by an instrument in writing under my, or their, or one
of their hands and seals, should particularly describe and ascertain the
nature of the said Invention, and in what manner the same was to be
performed, and cause the same to be filed in the Great Seal Patent Office
within six calendar months next and immediately after the date of the
said Letters Patent.
NOW KNOW YE, that I, the said Henry Bernoulli Barlow, do hereby
declare the nature of the said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and
by the following statement (that is to say) :-
:-
This Invention is applicable to slubbing and roving frames, and other
similar machines for preparing cotton and other fibrous substances, and
to machines for spinning and doubling, and it consists in an improved
mode of driving the spindles of such machines, and of arresting the
motion of any spindle without interfering with the working of the other
spindles.
In performing this Invention the spindles to be driven are supported
in two bolster rails, and near the lower end of each spindle is fixed a
friction pulley, made by preference of leather, but any other suitable
substance may be used, this pulley rests upon another friction pulley made
of cast iron or other suitable substance fixed on a horizontal shaft, and on
this shaft are fixed as many pulleys as there are spindles to be driven.
This horizontal shaft is driven as usual, and corresponds to the shaft now
in use when the spindles are driven by bevel wheels and pinions. In
front of each spindle, and supported by studs fixed in the bolster rails, is
a flat vertical rod, the lower end of which is bent at right angles, and

page_text: passes under the lower end of the spindle. When it is required to stop
a spindle the attendant slightly raises this rod, and thereby lifts the
friction pulley on the spindle out of contact with the pulley on the
horizontal shaft.
The above improvements can be applied either combined or separately,
and the apparatus for stopping the spindles can be applied to machines
of the ordinary construction where bevel wheels and pinions are employed.
The advantages obtained are perfect regularity of speed, and con-
sequently of twist, saving of power, avoidance of noise, and great facility
in stopping each spindle independently of the others.
And in order that this Invention may be fully understood and readily
carried into operation, I will proceed to describe the accompanying Sheet
of Drawings, reference being had to the figures and letters marked
thereon.
It
Figure 1 represents a side view of a spindle with a flyer for a throstle
frame to which these improvements are applied, but the improvements
are equally applicable to spindles without flyers; Figure 2 is a front
view of the same, and Figure 3 is a front view of the upper part of the
stop rod. To the lower end of the spindle I is fixed the conical friction
pulley A, which is made by preference of compressed leather, but may
be made of any other suitable material; the pulley A fits accurately on
the circumference of the conical friction pulley B, which is fixed on the
shaft H, to which motion is communicated in the ordinary manner.
is evident that the shaft H must be provided with as many conical
pulleys B as there are spindles to be driven. The spindles are sup-
ported in bearings G, G', in the rails T, and the lower extremity of
the spindle instead of being supported in a footstep as now customary is
without support, and terminates at a little distance from the bent end of
the vertical rod C; this rod is provided with two slots D and E, through
which pass the screws b, and the rod can be raised by the attendant
acting on the handle p, so as to bring the bent end of the rod against
the end of the spindle when it is requisite to lift the conical pulley A
out of contact with the pulley B. In Figure 1 the conical pulleys are
shewn in contact, and when in this position the
revolving at the speed given by the pulley B to the
red lines in Figure 2 represent the position of the parts when the conical
pulleys are disconnected, and the spindle is stopped, the rod C is raised,
and it is held up by the upper screw b, on to which the rod is hooked as
spindle would be
pulley A, but the

page_text: shewn in Figure 3. As soon as the broken yarn has been pieced the
attendant unhooks the rod C from the upper screw b, and the spindle is
then at liberty to drop until the friction pulley A again comes in contact
with the pulley B. I wish it to be understood that the particular
arrangement for disconnecting the friction pulleys may be considerably
modified, but the mode described is found simple and convenient in
practice. Although in the preceding description it is stated that the
leather cone A works in contact with a cast-iron conical pulley B, I wish
to observe that both the cones may be made of leather or other hard sub-
stance, the cone A may be made of hardened vulcanized india-rubber,
gutta percha, compressed wood or sawdust, pasteboard, or other suitable
material, and the pulley B is made of cast iron, or both A and B may be
made of leather or other hard substance. The most important point is
to select a substance or material that is hard, compact, homogeneous,
and capable of being turned in a lathe. In treating leather, paper, paste-
board, sawdust, and similar substances, it is first necessary to compress
them, or to compress and glue them by the well-known means. now
employed in preparing cylinders for other purposes.
The main features of this Invention consist,-
First. In an improved mode of transmitting motion by friction, and
obtaining better results than those produced by the most perfect toothed
gearing, and at the same time without noise.
Secondly. In a simple arrangement of mechanism for stopping each
spindle independently of the others. These two improvements may be
used in combination or separately, and it is evident that the apparatus
for stopping the spindles may be applied to machines in which the
spindles are driven in the ordinary manner. I wish also to observe that
these improvements may be applied either separately or combined to
slubbing frames, roving frames, and other machines for preparing cotton
and other fibrous substances, and to mules and throstles for spinning and
doubling. The chief advantages of these improvements are the great
simplicity of construction, the accuracy of the results, the economy of
the motive power, the power of driving the spindles at the greatest
velocity without noise, the dispensing with grease requisite for toothed
gearing, the means of stopping each spindle independently of the others,
the facility it affords for doffing the full bobbins without stopping the
whole machine, and dispensing with the footstep in which the lower
end of the spindle usually works. All these advantages are obtained,

page_text: while the number of attendants is reduced, and the length of a machine
constructed according to these improvements may be considerably
reduced.
Having thus stated the nature of the Invention, and the manner of
performing the same as communicated to me, I declare that I claim,-
First. The improved mode of transmitting motion to the spindles of
machines for preparing, spinning, and doubling cotton and other fibrous
substances by the friction of two cones, one of which is made of metal,
and the other of compressed leather or other suitable hard substance, or
both are made of leather or other hard substance as shewn and described.
Secondly. The improved arrangement of parts for stopping instantly
any spindle independently of the others, as shewn and described.
And, thirdly, the application of the above improvements when used in
combination or separately, as described.
In witness whereof, I, the said Henry Bernoulli Barlow, have here.
to set my hand and seal, this Thirteenth day of January, One
thousand eight hundred and sixty-nine.
