I WILLIAM TAYLOR, of 19 Hill Street, Oldham, in the County of Lancaster,
Engineer, do hereby declare the nature of said Invention for IMPROVEMENTS IN
DRIVING MECHANISM FOR SPINNING AND DOUBLING FRAMES, 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 improvements in the driving mechanism of ring or throstle
spinning and doubling frames and the objects of my improvements are, first, to enable
increased speed to be imparted to the machine when required without necessarily
increasing the diameter of the driving pulley on the main shaft or reducing the
diameter of the pulley on the tin roller shaft, and, secondly, in machines where two
tin rollers are employed to drive the second roller positively and at the same speed as
the first without the use of toothed gearing.
In carrying my Invention into effect I employ a countershaft supported in bearings
bolted to the end frame of the machine, this countershaft carries a band wheel with
preferably two grooves for an endless rope or band which passes round a grooved
pulley on the end of each tin roller shaft and also over a tension pulley.
In a modification of my Invention I employ a separate rope or band to drive each
tin roller and a separate tension pulley for each rope.
My invention may also be applied to machines in which a single tin roller is
employed.
And in order that my Invention may be fully understood and readily carried into
effect I will describe the accompanying two Sheets of Drawings reference being had
to the figures and letters marked thereon.
Figure 1 is an end view and Fig. 2 a side view partly in section of a spinning or
doubling frame with two tin rollers to which my Invention is applied and Fig. 3 is a
view representing the end of a spinning or doubling frame to which a modification of
my improvements is applied.
In Figs. 1 and 2-a is an additional end frame projecting beyond the ordinary end
frame a, see Fig. 2; bb the shafts of the ordinary tin rollers for driving the spindles.

which are not shown, on each shaft is secured a double grooved pulley cc¹ respectively;
d is a countershaft supported in brackets ee' bolted to the end frames aa¹. The
countershaft carries a pair of fast and loose pulleys of which the fast pulley
which is driven by means of the belt, from the driving shaft is secured io a flanged
bush keyed on the shaft. To the flange of the bush is bolted a pulley i with two
g
grooves for the endless driving rope or band j. Secured to the frame a at a² is a
bracket which carries a stud on which is mounted loosely a tension pulley / a
screw mpasses through the stud which can be moved up and down in the bracket to
alter the position of the pulley and adjust the tension on the ropej by turning a
handwheel m' fixed on the screw m.
The course of the endless rope or band is as follows:-Starting from the joint X
the rope is first taken under the double grooved pulley e of the tin roller & then up to
and over the tension pulley 1, then to the pulley of on the tin roller shaft back
to the tension pulley 1, down again to the pulley c¹, up to the driving pulley i, down to
the pulley e back again round the pulley and down to the point X near the pulley c
where the ends of the rope are pieced together. In this manner both the tin
rollers are driven at a uniform speed by one endless rope the tension on which is
readily governed by the adjustable pulley 1.
The use of the countershaft d permits of great change of speed without increasing
or altering the size of the driving pulleys on the main shaft or reducing the size of
those on the tin rollers the speed being changed readily by simply altering the size of
the rope driving pulley i.
In the alternative arrangement, Fig. 3, instead of driving the tin rollers by one
rope they are each driven by an independent rope respectively which may be
either single or double each endless rope having a separate adjusting or tension
pulley P
In frames where only one tin roller is employed the endless rope or band which
may be used either double or single would be taken from the grooved pulley on
the countershaft round a grooved pulley on the tin roller shaft and over a tension
pulley.
Having now particularly described and ascertained the nature of my said Invention
and in what manner the same is to be performed I declare that what I claim is-
1. Driving the tin rollers or tin roller of a spinning or doubling frame by means
of an endless rope or ropes from a pulley on a countershaft substantially as herein
described and as illustrated by the Drawings.
2. In a spinning or doubling frame the combination with a grooved pulley on a
countershaft and grooved pulleys one on each tin roller shaft of an endless rope or
ropes adjustable as to tension said countershaft being driven from the main driving
shaft substantially as herein set forth.
3. In a spinning or doubling frame with one tin roller the combination of a
grooved pulley on a countershaft a grooved pulley on the tin roller shaft and an endless
rope adjustable as to tension substantially as herein set forth.
