Improvements in and in on WORD
Imparting Motion to the Spindles in Spinning Machines.
I, JAMES YATE JOHNSON, of 47 Lincolns Inn Fields in the County of Middlesex,
Gentleman, do hereby declare the nature of this Invention, which has been commu-
nicated to me from abroad by Etienne Charles Armand Masson-Pinel, of Lenclos,
Aube, in the Republic of France, retired spinner, to be as follows:-
This Invention of improvements in apparatus for driving or imparting motion to
the spindles of spinning machines consists essentially in providing means such as the
mechanical arrangements hereinafter described or their equivalent for automatically
regulating and maintaining the tension of the driving cords by which motion is
transmitted to the said spindles.
In the case of machines in which the spindles are driven by a drum cylinder or
tin roller rotating on a vertical axis one endless cord is employed to drive all
the spindles being carried from the drum first round the wharves of two
spindles for example, then back to the drum, and thence round two other
wharves and so on, the wharves being arranged in different horizontal planes so that
the cord follows an inclined or helical path. At a suitable point between the drum or
tin roller and the wharves one or more lengths of the driving cord is or are caused to
pass round a tension pulley or pulleys carried by a frame sliding in guides or carried
on a pivoted arm so as to be capable of moving in a direction approximately at right
angles to the cord. This frame is connected to an adjustable or other counter-weight
working in or on vertical guides and which acts upon the driving cord through the
frame and tension pulley in such a manner as to regulate and maintain the tension of
the said cord perfectly uniform and thus obviate all the disadvantages or defects
in the spinning arising from the unequal tension of the cords in the ordinary
arrangements.
In the case of tin rollers or cylinders working on a horizontal axis a single cord is
employed as before to drive a large number (say 30 or 50 or upwards) of spindles
the cord being caused to pass from a wharve at one end of the series, for example, to
the cylinder and thence round the second wharve back to the cylinder again and so
on throughout the series until it is worked to the other end of the cylinder. Here

page_text: the cord after passing round the last wharve is carried round a guide pulley or pulleys
to a tension pulley operated by a vertically guided counter-weight as hereinbefore
described (or the tension pulley might be directly connected to the said weight if
preferred). From this tension pulley the cord passes round another guide pulley or
pulleys and back to the wharve at the other end or beginning of the series.

The counterweight is arranged to act upon a rocking lever connected with a stop
motion provided with suitably balanced weights whereby, in case the cord breaks,
the machine is instantaneously and automatically stopped by shifting the belt for
example.
The driving cord is preferably composed of strands of cotton, hemp, china grass or
ramie, or other suitable fibres, which are first plaited separately, then twisted separately
and combined in any desired number to form a cord.

I JAMES YATE JOHNSON of 47 Lincolns Inn Fields in the County of Middlesex
Gentleman do hereby declare the nature of this invention which has been com-
municated to me from abroad by Etienne Charles Armand Masson-Pinel of Lenclos
Aube in the Republic of France, retired Spinner and in what manner the same is
to be performed to be particularly described and ascertained in and by the following
statement :-
This Invention of improvements in and in connection with apparatus for driving
or imparting motion to the spindles of spinning machines consists essentially in
providing means such as the mechanical arrangements hereinafter described or their
equivalents for automatically regulating and maintaining the tension of the driving
cords or the like by which motion is transmitted to the said spindles.
In the case of machines in which the spindles are driven by a drum cylinder or tin
roller rotating on a vertical axis, one endless cord or the like is employed to drive all
the spindles, the said cord being carried from the drum first round the wharves of two
spindles for example then back to the drum and thence round two other wharves and
so on, the wharves being arranged in different horizontal planes so that the cord
follows an inclined or helical path.
At a suitable point between the drum cylinder or tin roller and the wharves a
length or lengths of the driving cord is or are caused to pass round a tension
pulley or round tension pulleys carried by a frame sliding in guides or carried on a
pivoted arm so as to be capable of moving in a direction approximately at right angles
to the cord.
This frame is connected to an adjustable or other counterweight working in or on
vertical guides and which acts upon the driving cord through the frame and tension
pulley in such a manner as to regulate and maintain the tension of the said cord
perfectly uniform and thus obviate all the disadvantages or defects in the spinning
arising from the unequal tension of the cords in the ordinary arrangements.
In the case of tin rollers or cylinders working on a horizontal axis a single cord is
employed as before to drive a large number (say 30 or 50 or upwards) of spindles
the cord being caused to pass from a wharve at one end of the series for example to
the cylinder and then round the second wharve back to the cylinder again and so on
throughout the series until it is worked to the other end of the cylinder. Here the
cord after passing round the last wharve is carried round a guide pulley or pulleys to
a tension pulley operated by a vertically guided counter weight as hereinbefore
described (or the tension pulley may be directly connected to the said weight if

preferred). From this tension pulley the cord passes round another guide pulley or
pulleys and back to the wharve at the other end or beginning of the series.
The driving cord is preferably composed of strands of cotton, hemp, china grass or
ramie, or other suitable fibres which are first plaited separately then twisted separately
and combined in any desired number to form a cord.
And in order that the said Invention may be fully understood I shall now proceed
more particularly to describe the same and for that purpose shall refer to the several
figures on annexed Sheets of drawings the same letters of reference indicating
corresponding parts in all the corresponding figures.
Figure 1 represents a diagramatic side elevation illustrating this Invention as
applied to a spinning machine with roller on a vertical axis.
Figure 2 is a plan of the same.
Figure 3 is an end elevation of tension regulating appliance.
Figures 4 to 9 are modifications hereinafter described.
The tension regulating appliances are fixed to the interior of the carriage of the
machine and close to the cylinder T as shewn in Figures 12 and 3. The tension
appliances consists of a guide A in which slides a support B carrying a spindle D
on which are mounted one or several pullies Caccording to the number of lengths m of
the driving cord used to drive the spindles, the sheaves of which cord are
shewn at n.

One end of a cord X is attached to a pin on the support B. The said cord X
passes over pullies E E and thence under a pulley attached to the counterweight P.
The other end of the cord being carried up and secured to a fixed point as shewn in
Figure 3. This arrangement insures a constant tension in accordance with the weight
used. Figures 5 shews a modification of this arrangement wherein the spindle Dis
mounted on a lever L moveable on a centre at l carried by supports s attached to the
frame work. The extremity of the lever L is fastened to the counterweight P by
the cord X which passes over the pullies E E.
The effect of this method is similar to the former one, all the lengths m of the
driving cord being equally tightened by the action of the counterweight P. In both
these arrangements the counterweight P is shewn as being guided in a frame K.
Figure 4 shews a slight modification in the arrangement of the weight P and
frame K.
When the invention is applied to machines having horizontal driving cylinders, it
may be arranged as shewn in figures 6 to 9.
These figures shew a pulley C mounted on a support B sliding in a guide A under-
neath and at right angles to the cylinder T. The returning lengths m of the single
driving cord on passing over the wharves and cylinder as shewn in figure 7,
its mid-part over the pulley C being deflected and guided in the right path by the
pulleys R carried by the slide A.
passes at
The support B is fastened by the cord X attached to the counterweight P substantially
as in the preceding arrangement.
Figures 8 and 9 shew another arrangement wherein the parts A and B are omitted
one of the lengths m of the driving cord m passing over the pullies M and N and
under the pulley G of the counterweight P.
In all these methods the counterweight should be of a weight determined
beforehand or it might be in the form of a box filled with pieces of lead or
other heavy material so as to afford a means of readily regulating the tension on the
driving cord.
I do not limit myself to the precise details described, for they may vary in
accordance with the different kinds of machines to which the Invention is applied.
This Invention has the advantages that there is great regularity of the product of
the machine and that thicker and more durable cords for driving the spindles can
be used.
To ensure the proper working and durability of the driving cords it is preferred to
manufacture them as aforesaid; the strands being separately plaited and twisted and
then wound together in the number of strands-required..
