A communication to me from abroad by
Etienne Charles Amand Masson of Paris in the Republic of. France.
The object of the invention is to drive the spindles of mules and other machines
for spinning doubling and twisting cotton and other fibre simultaneously at an
uniform speed by one belt or cord that passes over the pulleys of a number of
spindles
On the spindles I fit pulleys with a cylindrical surface for the belt to run on and
I form a recess or cup in the upper portion of each pulley to catch the oil that
escapes from the upper bearing and I make a hole or holes descending through the
pulley for the oil to pass through so that it will not get on to the surface of the
pulley
I give motion to the spindles by a driven belt that passes over all these pulleys
and the tension is secured by guide or friction pulleys which cause the belt to press
on the spindle pulleys
These guide pulleys may be fitted with the same arrangement for carrying away
the oil.
The belt after passing along and driving the spindles is carried round small
horizontal guide pulleys on the mule carriage when the invention is applied to a
mule and returns along the carriage over another guide pulley to a loose vertical

headstock, and round a large driving wheel secured to the main shaft from which
it returns to the spindles.
In throstle and doubling frames a similar arrangement of spindle and guide
pulleys is employed for the endless driving belt. The spindle and guide pulleys are
either slightly convex or grooved on their face to suit respectively a belt or cord.
The tension needed to drive the spindles is obtained by means of the row of
guide pulleys (each of which serves to tighten the belt on two spindles) mounted
on short spindles which revolve in bearings in the bolster and footstep rails or in
an independent bracket.

HENRY BERNOULLI BARLOW of Manchester in the County of Lancaster
Consulting Engineer and Patent Agent. "IMPROVEMENTS IN MACHINERY FOR
SPINNING, DOUBLING AND TWISTING A communication to me from abroad by
Etienne Charles Amand Masson, of Paris in the Republic of France
The object of the invention is to drive the spindles of mules and other machines
for spinning doubling and twisting cotton and other fibre simultaneously at an
uniform speed by one belt or cord that passes over the pulleys of a number of -
spindles.
On the spindles I fit pulleys with a cylindrical surface for the belt to run on and
I form a recess or cup in the upper portion of each pulley to catch the oil that
escapes from the upper bearing and I make a hole or holes descending through the
pulley for the oil to pass through so that it will not get on to the surface of the
pulley. I give motion to the spindles by a driven belt that passes over all these
pulleys and the tension is secured by guide or friction pulleys which cause the belt
to press on the spindle pulleys. These guide pulleys may be fitted with the same
arrangement for carrying away the oil.
The tension needed to drive the spindles is obtained by means of the row of
guide pulleys (each of which serves to tighten the belt on two spindles) mounted
on short spindles which revolve in bearings in the bolster and footstep rails or in
an independent bracket.
The belt after passing along and driving the spindles is carried round small
horizontal guido pulleys on the mule carriage when the invention is applied to a
mule and returns along the carriage over another guide pulley to a loose vertical
guide pulley on the headstock, thence to a similar pulley at the back of the
headstock and round a large driving wheel secured to the main shaft from which it
returns to the spindles.
In throstle and doubling frames a similar arrangement of spindle and guide
pulleys is employed for the endless driving belt.
And in order that this Invention may be fully understood and readily carried
into effect I will proceed to describe the accompanying Sheet of Drawings reference
being had to the figures and letters marked thereon.
Fig. 1 is part of a front view of a mule. Fig. 2 is a plan of Fig. 1 but showing
both ends of the carriage. Fig. 3 is an end view of the mule. Fig. 4 is an
elevation and Fig. 5 a plan (on an enlarged scale) of two spindles and pulleys and
one friction or guide pulley. Fig. 6 is a side view partly in section of a friction
pulley carried in a bracket. Fig. 7 is a plan of part of a spiuning or twisting
frame and Fig. 8 is a view of another arrangement for applying and regulating the
tension.
Similar letters refer to similar parts throughout the several views.
a is an endless cord or belt driven by a large pulley a¹. mounted on the driving.
shaft a². of the mule: bb are pulleys with cylindrical surfaces for the cord or belt
to run on secured to the spindles b. and which replace the ordinary spindle
wharves. Each spindle b. revolves in a footstep c in the bottom rail c'. and in a
bolster & in the bolster rail d'. see Fig. 4. A recess or cup c is formed in the
upper portion of each pulley to catch the oil that escapes from the bolster d and
small passages or channels e'. are made descending vertically through the pulley for
the oil to pass through so that it will not get on the surface of the pulley. All
the spindles b'. are driven simultaneously by the endless cord or belt a which passes
over all the pulleys b. Placed between and slightly behind the spindle pulleys b
are friction pulleys which give the necessary tension and cause the cord a to press

page_text: :
on the spindle pulleys b. These friction pulleys fare mounted on short spindles fl.
which have a top bearing in the bolster rail d. and a footstep in the bottom rail c'.,
see Fig. 4 if it is desired to reduce the length of the spindles f¹. the friction
pulley's may be mounted in a bracket g (as shown in Fig. 6) secured to any
convenient part of the machine: or the friction pulleys f may be secured in any
other convenient manner. The spindle pulleys b are always cylindrical in order to
ensure uniform speed of the spindles and the friction surface of the pulleys fis
concave when a cord is employed and slightly covex when a belt or strap is used..
To prevent oil running on to the surface of the friction pulleys f passages may be
made similar to those described for the spindle pulleys b.
The endless cord or belt a after passing between all the spindle pulleys 6 ant the
friction pulleys fpasses over two of the horizontal guide pulleys & mounted on the
mule carriage and returns along the carriage over another guide pulley / to a loose
vertical guide pulley i mounted on the headstock thence to a similar-pulley jat
the back of the headstock and round the driving wheel a'. from which it returns to 1
the spindles.
It will be seen from this description that the length and tension of the endless
cord a remain constant in every position of the mule carriage.
In spinning frames where toothed gearing takes the place of pulleys the driving
shaft of the gear may be used to drive a wheel over which the endless cord or belt
passes.
In Fig. 7 which shows such an arrangement, k is the driving shaft near one end
of which is secured the bevel wheel which drives the bevel wheel . secured
to a vertical shaft . upon which is the large wheel : the endless cord or band a
passes from the larger wheel . to the spindles and friction pulleys fas before
described.
In Fig 8-The tension of the cords can also be obtained by mounting the
spindles of the tension pulleys fin a separate bracket i, guided at the top and at
the bottom and subject to the elastic pressure of a spring z the tension of which is
regulated by the screw v. In this way any of the tension pulleys: f may-be-3
regulated simply and easily and this is an appreciable advantage.
This invention may also be applied to throstle spinning and doubling frames in
which a separate cord is employed to drive each spindle. By this means the
objections to separate cords are overcome as separate cords never drive the spindles
at one uniform speed and cause bad work and waste when they break or get so
slack as to require taking up.
This invention can be applied at small cost to all existing spinning doubling and
twisting frames whether driven by hand or power and in new mules the carriage
can be made narrower and lighter.
Having stated the nature of this Invention and described the manner of 4
performing the same.
I declare that I claim
1. The use of an endless cord or belt for driving the spindles of mules throstle
spinning frames and other spinning and doubling frames for the purposes
described.
2-The combination of the pulleys b fixed to the spindles b'. with the friction
pulleys for the purpose described and as shown in reference to Figs. 4, 5 and 6.
In witness whereof I the said Henry Bernoulli Barlow have hereunto set my
hand and seal this twenty third day of April One thousand eight hundred
and eighty three.
