and Doubling Machinery.
I, CHARLES WILLIAM JONES, of the city of London, in the county of Middlesex,
in the Province of Ontario, in the Dominion of Canada, produce dealer, do hereby
declare the nature of my invention for IMPROVEMENTS IN APPARATUS FOR DRIVING
THE SPINDLES IN SPINNING AND DOUBLING MACHINERY, and in what manner the
same is to be performed, to be particularly described and ascertained in and by the
following statement :—
My invention relates to spinning and doubling machinery in which the spindles are
driven by cords or bands running over a cylinder or drum.
The objects of my invention are the construction of machinery of the class referred
to in such manner that the slack of the band is readily and automatically taken up,
that thereby the yarn or other product is evenly and uniformly drawn and twisted, a
more even and better quality of yarn thread or other product obtained thereby, the
wear and tear of the bands reduced and the useless extra expenditure of driving
power, due to over-tight bands, prevented.
I attain these objects briefly stated in the following manner. All the spindles on
one side of a machine, or one half or other fraction of the whole number of spindles
on one side, are driven by one continuous endless band, running over the wharf of
each spindle and once over the driving cylinder for each spindle and running over
one or more pivoted arms carrying friction pulleys or wharves and provided with
tension springs which tend to tighten the band.
In describing my invention more fully, referonce is to be had to the accompanying
drawing, forming a part hereof and in which
Fig. 1 is a top view of a driving drum and series of spindles driven thereby,
having my improvements applied.
Fig. 2 is a side elevation of the same.
Fig. 3 is a perspective view of a spring or tension arm.
C is the driving cylinder journaled and driven in the usual manner. S are the
spindles carried in and upon rails and journaled as usual and having wharves s, and B
is the continuous endless driving band, giving motion to the spindles from the
cylinder. A A' A' are three pivoted tension arins, each carrying at its end a wharve
or friction pulley a over which the band B passes, and pivoted to a bracket or foot a¹,
adapted to be bolted or otherwise secured to the machine frame with which it forms a

page_text: hinge joint, a spring a¹ being coiled around the hinge pin ɑ™, tending to push the
arm in a straight line with the foot. These arms or brackets are so disposed that
they tend to draw the band passing over the wharves a tight. One of these arms or
brackets, A, is placed between the cylinder C and spindles S, and in the centre of the
row of spindles which the band B is to drive, and this tension arm alone may be
made to suffice, if preferred, and the other two dispensed with and replaced by simple
guide pulleys journaled in fast brackets. Instead of the said fast guide pulleys the
tension arms or spring tighteners A'A' may however be used as shown in the drawing.
Instead of the coiled springs all any other spring may be used that will produce the
same result. The band B is passed under and partly around the cylinder C opposite
the spindle at one end of the row to be driven, then around the wharves of the said
spindle S and again under and partly around the cylinder C and to the wharve of
the next spindle, and so on, until the centre of the row of spindles is reached. Here,
the band B, instead of being passed at once around the wharves of the spindle is
passed over the wharve or pulley a in the tension arm A, then back under and partly
around the cylinder C and then to the wharve s of the next spindle S and so on to the
end of the row of spindles. After all the spindles are thus connected, the band is
passed under and partly around the cylinder C, and then over the pulley or wharve a
in the tension arm A placed opposite said end spindle, thence to the pulley or wharve a
of the tension arm A placed opposite the end spindle at the other end or starting
point, and in line with the former, and then the ends of the band are spliced to form
a continuous endless band running over the wharves s of all the spindles S in the
row and over the wharves a in the tension arms, or one tension arm and two fast
brackets.
In threading the band B, the tension arm or arms A and A' are drawn towards the
cylinder Cagainst the tendency of the springs, so that the reaction of the latter will
move the arm away from the cylinder and take up the slack of the band.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :
1. In spinning and doubling machinery the combination of the cylinder C, a series
of spindles S, friction pulleys a journaled in spring-actuated arms A A¹ and a
continuous endless band B passing over said cylinder, spindles and pulleys a,
substantially as set forth.
2. In spinning and doubling machinery, the combination of a cylinder C, a series
of spindles S, a friction pulley a journaled in a spring-actuated tension arm A, guide
pulleys a journaled opposite the spindles at the ends of the row, and the continuous
endless band B passing over said cylinder, spindles and pulleys a, substantially as set
forth.
3. In a tension device for spinning and doubling machinery, the combination of a
cylinder C, a series of spindles S, a friction pulley a journaled yieldingly, guide
pulleys a journaled opposite the spindles at the ends of the row, and the continuous
endless band B passing over said cylinder, spindles and pulleys a, substantially as set
forth.
4. In a tension device for spinning and doubling machinery, an arm A hinged to
a bracket or foot a¹ and provided in the hinge joint with a spring a", and having
journaled at its end a friction pulley a, in combination with a continuous endless band B,
substantially as set forth.
