PROVISIONAL SPECIFICATION.
Improvements in Counter-faller Weighting Apparatus for Mules.
1 JOHN MCQUEEN of the firm of Messrs. John Hetherington & Sons Limited
of the Vulcan Works, Pollard Street, Ancoats, Manchester, in the County of
Lancaster, Machine Makers, do hereby declare the nature of this invention to be
as follows:-
My invention relates to the relieving of the weight upon the counter-fallers of
mules used in the spinning of textile materials.
During the run out of the carriage the said weight is relieved by the faller shaft
but when the carriage is near the end of its run out it is necessary to relieve the
tension of the yarn whilst the backing off is taking place. The weighting of the
counter-faller is usually effected by means of a load lever which is connected by
means of a chain with a sector lever upon the counter-faller shaft and this lever
has come in contact with a bowl at the required times so that the lever has been
raised to relieve the weight upon the counter-faller.
I employ a special relieving lever which is connected by means of a spring with
the load lever.
This relieving lever is inclined or is formed with an incline upon which the bowl
or stationary abutment acts to turn the lever upon its fulcrum at the required
times the movement of the lever being transmitted to the load lever through the
spring thereby relieving the weight with less shock and permitting the faller to
be more heavily weighted. In practice I form each of the two levers with two
arms the second arms of the levers being connected by a spring so that when the
incline end of the relieving lever is lifted the load end of the load lever will be
gradually raised.
When the carriage runs in the load lever is gradually lowered so as to put the
weight upon the counter-faller.
་
The construction of the two levers may be varied so long as the connection of
the two is retained.

Improvements in Counter-faller Weighting Apparatus for Mules.
I JOHN MCQUEEN of the firm of Messrs. John Hetherington and Sons,
Limited, of the Vulcan Works, Pollard Street, Ancoats, Manchester, in the
County of Lancaster, Machine Makers, 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 and accompanying
drawings:
My invention relates to the relieving of the weight upon the counter-fallers of
mules used in the spinning of textile materials.
During the run out of the carriage the said weight is relieved by the faller
shaft but when the carriage is near the end of its run out it is necessary to relieve
the tension of the yarn whilst the backing off is taking place. The weighting of
the counter-faller is usually effected by means of a load lever which is connected
by means of a chain with a sector lever upon the counter-faller shaft and this

page_text: lever has come in contact with a bowl at the required times so that the lever has
been raised to relieve the weight upon the counter-faller.
I employ a special relieving lever which is connected by means of a spring with
the load lever.
This relieving lever is inclined or is formed with an incline upon which the bowl
or stationary abutment acts to turn the lever upon it's fulcrum at the required times
the movement of the lever being transmitted to the load lever through the spring
thereby relieving the weight with less shock and permitting the faller to be more
heavily weighted.
The methods which I have adopted when carrying my invention into effect are
illustrated in the accompanying drawings.
In the said drawings,
Fig. 1 is a cross sectional view of a mule carriage with such of the attached
parts as are necessary to the sufficient illustration of
my
invention.
Fig. 2 is a front view of the counter-faller weighting lever and the relieving
lever.
.
In Fig. 1 a--which is drawn as in section-represents the mule carriage is the
winding faller shaft the counter-faller shaft and d the counter-faller weighting
lever these parts being of ordinary formation.
The front end of the lever d is connected by means of a chain with a sector
lever upon the counter-faller shaft as is usual. The weight relieving lever which
I have added is represented by E. In the example this lever is mounted upon the
same fulcrum pin or stud as the weighting lever d but I do not confine myself to
this method of mounting the lever. The relieving lever E is connected with the
weighting lever by means of a spring in such a manner as that when the free end of
the relieving lever is raised a lifting strain is transmitted through the connecting
spring to the weighting lever and the load acting upon the sector c¹ is relieved to
an extent proportionate to the extent to which the end of the relieving lever is
raised. In the example the relieving lever is formed or provided with an upward
extension E and from the upper end of this part a spiral spring f extends down-
ward to the weighting lever and is attached to the same or to a stud or part d'fixed
to the said lever. The relieving lever is sustained in its normal position with
relation to the weighting lever by means of a finger h attached to or formed upon
the lever and bearing upon the weighting lever or the lever may be sustained in
any suitable manner. By preference the finger h or the connection of the spring
with the part E' should be so adjusted as that a slight normal tension is put upon
the spiral spring. The lower edge of the relieving lever is inclined from the
horizontal for some distance from the outer end of the lever as clearly shown in the
drawing.
A fixing 9 is provided with a vertically adjustable rounded block g' and is secured
to the floor in such a position as that the outer end of the relieving lever will come
upon the rounded block when the carriage is near the end of the run out as shown
in the drawing.
It will be apparent that the continued motion of the carriage in the running out
direction-indicated by the arrow-after the outer end of the relieving lever has
touched the block g' will cause the relieving lever to be raised and a tension will
thereby be put upon the spring of whereby the load upon the counter faller will be
relieved to an extent corresponding to the tension of the spring. The degree of
relief can be regulated by adjusting the block g¹.
When the carriage runs in the lever d is gradually lowered or otherwise the
tension of the spiral spring is gradually reduced and the full load is permitted to
act upon the counter-faller.
If preferred a bowl might take the place of the block gl.
Fig. 3 illustrates a modification in the construction of the parts. In this example
each of the two levers d and E is formed with two arms and the additional arms d
and E of the levers are connected by means of a spiral spring f' the arm d³ being
curved upward to take hold of the upper end of the spring. It will be seen that

page_text: when the front arm E of the relieving lever is raised the spring will be put in
tension and will act to draw downward the arm d³ whereby the load upon the
counter-faller will be relieved.
It will be obvious that the arrangements may be otherwise modified without
interfering with the action of the parts so long as there is a spring connection
between the two levers.
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) The combination of parts substantially as and for the purpose set forth and
indicated.
2) In combination with the counter-faller weighting lever of a mule the relieving
lever connected by means of the spring with the weighting lever and adapted to be
acted upon at times by a part fixed to the floor and to be thereby raised substantially
as and for the purpose set forth and indicated.
3) In a spinning mule a relieving lever having a spring connection with the
counter-failer weighting lever and adapted to be acted upon by a fixed part when
the carriage nears the end of its outward run the relieving lever at such time
acting through the connecting spring upon the weighting lever to raise the loaded
end of such lever for the purpose set forth.
