Improvements in Apparatus for Driving the Spindles in Machinery
for Spinning, Doubling, and Twisting.
We, CHARLES WILLIAM JONES, of the City of London, in the county of Middlesex,
produce dealer, THOMAS MILBURN, merchant, and ALFRED MACDOUGALL, barrister,
both of the City of Toronto, in the county of York, and all in the Province of
Ontario, in the Dominion of Canada, do hereby declare the nature of our invention
for IMPROVEMENTS IN APPARATUS FOR DRIVING THE SPINDLES IN MACHINERY FOR
SPINNING DOUBLING AND TWISTING, and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following statement:-
Our invention relates to devices used in machinery for spinning doubling
twisting etc. of fibrous materials in which the spindles are placed in one or more
rows and are driven by bands from one or more central cylinders or drums, for
making the tension of said bands uniform.
The object of our invention is to provide a device of the simplest description that
can be cheaply manufactured and easily applied and that shall more effectually attain
its object.
Fig. 1 is a top view of that part of a machine showing the spindles, driving bands
and driving cylinder, having my improvements applied.
Fig. 2 is a cross section of the same.
A is the framing of a spinning doubling or twisting machine, B the banding,
C the driving cylinder and D the spindles having the wharves d, plain arrows
indicating the direction in which the various parts are running. A row or section
of a row of spindles is grouped together in one series and driven by one endless band
or cord B running from the cylinder C around the wharve d of the first spindle in
the group or series, then back to and around the cylinder again and so on to the last
spindle in the group or series, then passes around the cylinder again and back and
around a guide pulley D' at each end of the group or series journaled into or
near one of the spindle rails and back to the cylinder C. Opposite the centre
spindle of the group or series, or opposite the space between the two centre spindles,
the band, instead of passing to and around one of the wharves forms an extra or
slack loop passing over a grooved pulley E. The pulley E is journaled in a
clevice Ei held slidingly in a guide bracket F and secured to a cord e which is drawn
towards the spindles and passes over a friction pulley E" and is counter balanced
by a weight E
The counterweight E exerts a continuous and uniform tension on the cord e and
pulley E and thereby on the loop b, thus taking up the slack of said loop and of
the entire band by cord, B.
It will be seen that in the above arrangement the ends of the banding or cord B need
not be spliced to any exact length and that any variation of length due to expansion
or contraction or any other cause will be readily compensated by the rise or fall of
the counterweight and will not effect or vary the tension of the same.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
In a machine for spinning doubling twisting etc., of fibrous materials, the combina-
tion with the driving cylinder and spindles of the endless band B running continuously
forwards and backwards hetween and around the cylinder and a series of spindles
passing over a guide pulley at each end of the series and forming a loop 6 running
over a pulley E, a pulley E taking the loop b and journaled in a guided clevice E¹

the cylinder and counter balanced by a weight E and running over a friction
pulley E and the weight E secured to said cord e, substantially as set forth.
