PROVISIONAL SPECIFICATION.
Improvements in Cap Spinning and Twisting Machinery.
I, ALFRED AMBLER, of Prospect Mills, Wilsden, near Bingley, in the County
of York, Spinner, do hereby declare the nature of this invention to be as
follows:-
"
This invention relates to improvements in cap spinning and twisting machinery
and its primary object is to obtain an uniform "drag: or tension on the yarn as it
is twisted and wound on to the bobbin.
The said improvements consist in imparting a varying rotary motion to the
spindle and cap. The cap is arranged to revolve at its minimum speed whilst the
yarn is being wound on to that part of the bobbin having the largest diameter, and
the speed of the cap is gradually increased until its maximum speed is reached
when the yarn is being wound on to the smallest part of the bobbin.
"
The spindle may be mounted and driven somewhat similar to a flyer" spindle
but in this case the driving cylinder is driven at a varying speed by means of a
conical driving pulley or in any other convenient manner.
Dated this 6th day of June 1895.

Improvements in Cap Spinning and Twisting Machinery.
I, ALFRED AMBLER, of Prospect Mills, Wilsden, near Bradford, in the County
of York, Spinner do hereby declare the nature of this invention and in what
manner the same is to be performed, to be particularly described and ascertained in
and by the following statement :-
"
This invention relates to improvements in cap spinning and twisting machinery
and its primary object is to obtain an uniform "drag or tension on the yarn as it
is twisted and wound on the bobbin.
The said improvements consist in imparting a varying rotary motion to the
spindle and cap. The cap is arranged to revolve at its minimum speed whilst the
yarn is being wound on to that part of the bobbin having the largest diameter, and
the speed of the cap is gradually increased until its maximum speed is reached
when the yarn is being wound on to the smallest part of the bobbin.
Reference is to be had to the accompanying sheets of drawings forming a part
of this Specification, in which similar letters of reference indicate corresponding
parts in each of the figures.
Figure 1, represents an elevation of a portion of a cap spinning frame in which
such parts are shown as are necessary to illustrate the application of my
improvements thereto.
Figure 2, represents an end view and Figure 3 represents a plan view of the
same.

page_text: The tube driving cylinder A is mounted and arranged in the usual way to drive
the wharles B of the tubes revolving upon the spindles C, and the caps D are
carried on the tops of the spindles in the usual manner. Instead however of the
spindles C being stationary they are mounted in step bearings E in the bottom
rail E2 along each side of the frame and in bearings formed in the upper
rails E 3, E3 so that they are free to revolve in a similar manner to "fly". spindles.
The spindles C are provided with driving wharles B2 connected by the driving
tapes C 2 in any convenient way to the spindle driving cylinder C3 mounted in
bearings C4 on the end frames F at each end of the machine.
To impart a varying rotary motion to the cylinder C 3 this cylinder is driveu as
now described.
A pulley A 2 is mounted on the end of the shaft A 3 of the cylinder A, which
cylinder is assumed to be driven from the opposite end. The pulley A 2 is
connected by the driving belt A 4 to the pulley G fixed on the end of the shaft G 2
mounted in bearings formed in the end frame F and the cross frame F 2. A long
conical pulley G 3 is fixed on the shaft G 2 and is connected by the strap G4 to
the conical pulley H the axis of which is parallel to the axis of the cone G 3 but
the larger end of the one cone is opposite the smaller end of the other. The
cone H is fixed on a shaft H2 mounted in a similar way to G2 and has a
pulley H 3 on its outer end connected by the driving belt H4 to the pulley C5
which indirectly drives the cylinder C 3.
To vary the speed of the cylinder C3 in relation to the cylinder A the belt G4
is moved laterally to and fro from end to end of the cones G3 and H by means of
the travelling belt forks J, J embracing the belt G4 as it passes on to the cone H
and J 2, J2 embracing the belt as it passes ou to the cone G 3. The shanks J 3
and J 4 of the forks J and J 2 are fixed to the carriage J 5 mounted on the slide
rod J 6 fixed to the frames F and F 2 and the slide is coupled by the link K to
the arm K 2 of the bell crank lever K3 mounted upon the stud K4 projecting
from the bracket K 5 fixed to the end frame F. The arm K 6 of the lever K3
carries an anti-friction roller K 7 which bears upon the periphery of a heart
shaped cam N which cam at each revolution vibrates the lever K3 and thereby
moves the belt forks to and fro on the said cones. A weight K8 suspended from
the end of the arm K 6 keeps the anti-friction roller K 7 against the periphery of
the cam N. Guide rods J 8 and J 9 are provided to steady the belt forks.
The cam N is fixed on the cross shaft N 2 mounted in bearings in the side
rails N 3, N 3 (not shown in Figure 1) and driven by the worm wheel N 4 fixed
upon the said shaft. The worm N 5 engaging N 4 is secured on the end of the
short shaft N 6 mounted in bearings N 7 secured to the end frame F and this short
shaft is driven by the spur wheel N 8 engaging the pinion wheel N 9 fixed to the
pulley C 5 mounted upon the stud O2 projecting from the end frame F. The
pulley C 5 is driven by the belt H4 from the pulley H 3 fixed on the projecting
end of the shaft H 2. The cylinder C3 is also driven by the pinion wheel N 9
through the medium of the intermediate wheel P engaging the spur wheel P 2 on
the cylinder shaft C 6.
The belt G4 is preferably made with one edge thicker than the other as shown
in Figure 4 which represents a view ou a larger scale of the cone H with the belt
shown in section thereon. The thicker edge of the belt is placed towards the
smaller end of the cone H and in order to enable it to be similarly placed on the
cone G 3 the belt is twisted half way round both as it passes to and from
the cone G 3 as shown in Figures 2 and 3.
The spindles C may be driven from the cylinder C3 in any convenient manner
as for instance a number of them on each side of the frame may be driven by one
tape C2 as shown in Figure 3. In this case intermediate pulleys R2 loosely
mounted on studs R 3 fixed in the rails E2 and the tapes C2 pass round these as
it is passed from one wharle to the other.
