IMPROVEMENTS IN SPINNING MACHINERY
Year: 1884

page_text: I FRANCIS WILLIAMSON of Griffe Mill near Haworth in the County of York,
Spinner and Manufacturer, do hereby declare the nature of my Invention for
IMPROVEMENTS IN SPINNING MACHINERY, to be as follows:-
This Invention relates to certain improvements in spinning machinery and has
for its object the arrangement of the machine in such a manner, that when any
desired number of yards are spun on to the bobbins or tubes, the frame will be
stopped automatically independent of the lifter plate; this I accomplish in the
following manner :-
To the front bottom roller shaft above the spindles I secure a wheel which gears
with other wheels secured to a shaft mounted above the cylinder and extending
for a portion of the length of the frame; near to the other end of this shaft I
secure another wheel to which is fixed a projecting pin which comes in contact
with a rachet wheel every revolution, moving the same one or more teeth.
In connection with the rachet wheel is a cylinder, on the circumference of which
may be placed card plates which move with the cylinder every time the same is
actuated by the before named projecting pin. To one of these card plates is
secured a pin, the number and speed of the plates being regulated proportionate to
the number of yards of yarn to be given out by the front rollers, and when the
desired length has been spun on to the bobbins or tubes, the last named pin comes
in contact with a coupling on the stop rod, disconnecting the same and thereby
allowing one portion to be moved by means of a spring or weight and moves the
belt from the fast pulley to the loose pulley, thus stopping the machine.
Or my object may be accomplished without the card plates, by making the
cylinder of larger diameter and with a pin secured in the circumference, the
cylinder revolving proportionately less for the number of yards spun and when the
pin comes in contact with the coupling, the rod is disconnected and the driving
belt moved on to the loose pulley in the manner as before described.

page_text: I FRANCIS WILLIAMSON, of Griffe Mill near Haworth, in the County of York,
Spinner and Manufacturer, do hereby declare the nature of my Invention for
IMPROVEMENTS IN SPINNING MACHINERY, 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 certain improvements in spinning machinery and has
for its object the arrangement of the machine in such a manner that when any
desired number of yards are spun on to the bobbins or tubes, the frame will be
stopped automatically independent of the lifter plate and consists in connecting by
means of wheels one of the front roller shafts of the machine to actuate a cylinder
on which may be mounted card plates to one of which is secured a projecting pin,
which on coming in contact with one portion of the coupling on the stop rod
disconnects the latter thereby allowing one portion of the stop rod to be moved
by a weight or spring and move the belt from the driving pulley to the loose
pulley.
-
In order that my Invention and the manner of performing the same may be
better understood, I will further describe the same by reference to the accompanying
Drawings in which Figure 1 represents the end elevation of such portions of
spinning frame as are required to explain my Invention Figure 2 is a front view
of the same Figure 3 is an end view of the cylinder and catch wheel and Figure 4
is a view of the form of coupling I use on the stop rod.
:
The machine is driven by a belt running on the driving pulley A in the usual
manner and motion to the bottom front roller shafts as well as to the other
ordinary working parts of the machine are communicated in the usual manner.
To one of the front bottom roller shafts B I secure a wheel C which gives
motion by means of wheels C¹ and C² to the shaft D which is carried by suitable
brackets and to which is secured a pinion wheel E that gears with the wheel F to
which is secured a projecting pin G.
On each revolution of the wheel F the pin G comes in contact with the rachet
wheel H moving the same the distance of one or more teeth. In connection and
rotating with the rachet wheel H is what is usually termed a card "cylinder
upon which is mounted the card plates J which move with the "cylinder" every
time the same is actuated by the before mentioned pin G, the spring S keeping
the card plates and cylinder in position except when actuated in the manner
described.
The speed at which the "cylinder" is rotated, and the number of card plates J
mounted on the same are regulated by the number of yards of yarn to be delivered
by the front rollers B, a few of which are shewn on the shaft and when thus
regulated and the desired length has been spun on to the bobbins or tubes, the
pin K which is secured to one of the card plates J comes in contact with one
portion of the coupling secured to the stop rod L, raising the portion of the
coupling M, thereby allowing the weight P to slide the stop rod and belt guide R
in the direction of the arrow, moving the belt from the fast pulley A to the loose
pulley A thus stopping the machine.
My object may be carried into effect by dispensing with the card plates J and
substituting a cylinder of larger diameter for the small one in connection with
the rachet wheel H. When this method is adopted, the cylinder revolves
proportionately less for the number of yards spun, and to the circumference of the

page_text: cylinder I secure a pin similar to the pin K in card plates which on coming in
contact with the portion of the coupling M disconnects the rod and stops the
machine in the manner as before described.
On applying my Invention to the heavier class of spinning machines commonly
known as roving frames, the length of the roving is also measured as it is delivered
by the front rollers and spun on the bobbins, the machine stopping in the manner
as before described when a given number of yards are upon the bobbins, thus it
will be easily understood by persons conversant with spinning machinery that by
filling a yarn spinning frame with rovings thus prepared, all the rovings will be
done at about one and the same time thus to a very great extent the yarn is free
from piecings in consequence of the rovings, all running out about the same time
thus requiring less attention on the part of the operator until the empty roving
bobbins require replacing with full ones.
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:-
The stopping of spinning machinery by disconnecting the coupling on the stop
rod L substantially in the manner described and as illustrated by the accompanying
Drawings.
