THOMAS KNOWLES of Turton near Bolton in the County of Lancaster, Cotton
Spinner "IMPROVEMENTS IN APPARATUS FOR WEIGHING AND ASCERTAINING THE
COUNTS OF YARNS OR THREADS' SUCH APPARATUS BEING ALSO APPLICABLE TO
OTHER PURPOSES,"
My invention relates to apparatus for weighing and ascertaining the counts of
yarns or threads and consists in arrangements whereby I cause the weight of a
given length of yarn or thread to indicate, by means of a scale the number or
count of such yarn or thread aforesaid.
To accomplish this I employ a scale beam supported by a bracket attached to a
suitable base plate. To one end of such scale beam is attached a scale pan or other
similar receptacle to receive the yarn or thread of which it is desired to ascertain
the number or count. To the opposite end of the scale beam above referred to I
attach a scale pan or other similar part for receiving a weight or weights. One
of the arms of the scale beam aforesaid is formed to receive a weight which is
capable of being slidden along the said arm. I also provide weights which when
applied to the end of the scale beam above referred to opposite to that above
mentioned as carrying the length of yarn or thread to be weighed, shall represent
certain counts, and the weight above referred to as sliding upon one arm of the
scale beam gives the intermediate counts which are indicated by means of a pointer
attached to the said sliding weight and a suitably graduated scale or dial secured
to the base plate previously named.
.

page_text: The graduated scale or dial or the weights above referred to may have others
substituted therefor when it is desired to weigh or ascertain the numbers or counts
of greatly varying lengths or counts of yarn or thread.
I have hitherto referred to weighing yarns or threads for the purpose of ascer-
taining their counts or numbers but I would have it understood that my invention
may
be employed for other purposes such as indicating the value of a given
weight or quantity of material or other relative proportion of weight to length or.
valoa.

My Invention relates to apparatus for weighing and ascertaining the counts of
yarns or threads and consists in arrangements whereby I cause the weight of a
given length of yarn or thread to indicate by means of a scale the number or
count of such yarn or thread aforesaid-To accomplish this I employ a scale beam

formed to receive a weight which is capable of being slidden along the said arm-
I also provide weights which when applied to the end of the scale beam above
referred to opposite to that above mentioned as carrying the length of yarn or
thread to be weighed, shall represent certain counts and the weight above referred
to as sliding upon one arm of the scale beam gives the intermediate counts which

page_text: In order that my invention may be better understood and more readily carried
into effect I will now proceed to describe the same reference being made to the
drawing hereunto annexed in which Fig: 1 is a front elevation and Fig: 2 a side
view of Fig: 1 looking in the direction from A to B of Fig: 1 similar letters of
reference being applied to corresponding parts in each of the figures-At a is a
base plate to which is attached a pillar or bracket b The upper end of the pillar
or bracket b is provided with projecting parts c. d-Within the interior. of the
pillar or bracket b and capable of being slidden longitudinally therein is a rod e-
To the base plate a is secured a pillar f-Passing through a slot formed in the
pillar fis a lever g capable of being turned upon a pin h passing through the
pillar f―The end g₁ of the lever g passes beneath a pin e' projecting from the
rod e-Upon the end g₁ of the lever g being depressed as shown the end glis
elevated and carries with it the rod e-The upper end of the rod e is formed with
two projecting parts j k At l is a scale beam the arms of which are equal in all
respects such scale beam being provided with a centre m formed with knife
edges n. n¹ projecting from opposite sides of the scale beam and resting upon the
upper end of the parts j. k which are formed with flat surfaces to receive such
knife edges n. n. Suspended from the end of the scale beam is a hook O and
from the end of the said scale beam 7 is suspended a rod p provided with a
circular flange g the hook O and the rod p with the flange g being equal in weight-
Scale pans or other receptacles may be substituted if desired for the hook O or
flange q-Carried by the pillar or bracket b is an arm r the end ¹ of which carries
an upright pieces through which is formed a slot through which passes the end l'
of the scale beam -Carried by the arm r and secured thereto by screws is a
graduated plate t which is parallel with the plane of oscillation of the scale beam
Projecting from the scale beam is a bracket u secured thereto by means of a
screw, secured to the bracket u and projecting downward therefrom is a finger v
which passes in front of a scale w secured by screws to a bracket x. secured to the
pillar or bracket b by means of a screw-I will assume that the apparatus above
described is intended to be used for ascertaining the counts of yarn included
between the numbers sixty and eighty in which case the scale on the plate t will
be graduated in the following manner-I take a determined length of yarn, a
length I have found convenient in practice being two leas or two hundred and
forty yards a hank being equal to seven leas or eight hundred and forty yards, and
hang it upon the hook Ŏ-I also take a weight y shewn in Fig: 3 such weight
being in the form of a circular disc in which is formed a slot y* which enables such
weight y to be placed upon the rod p so as to rest upon the flange a suspended
from the scale beam -I also provide another weight z shown by Figs: 4. 5 of
which Fig 4 is a front view and Fig: 5 a side view of the weight -The
weight is formed with projecting jaws z' ' and also with a pointer the
jaws z..z are so formed that the weight can be placed upon the arm C of the
scale beam the jaws 2.2 enabling such weight to be slidden longitudinally
upon the scale beam while the pointer z³ indicates its position relative to the
graduations upon the plate t-The weight z is shown upon the scale beam 7 at D-
For convenience of description I will assume that the two leas of yarn above
referred to are formed of what is known as count N° 70s or yarn of which seventy
hanks of eight hundred and forty yards each weigh one pound avoirdupois―The
weight y and the weight z must be so proportioned that they shall balance the two
leas of yarn suspended from the hook O when the pointer is at a point about
midway between the ends of the scale t-This point is then marked and
numbered 70-I then by calculation or by means of yarn or thread or weights
placed upon the hook O in a manner similar to that above described find the
position upon the scale beam 1 to which the weight z must be slidden to balance
two leas of yarn or thread of the count numbered eighty when such yarn or thread
is placed upon the hook 0 1 then mark the scale t at the point indicated by the
pointer z³ in its last position, this point is then numbered eighty-I then in a
similar manner find the position to which the weight & must be slidden to balance
:

page_text: two leas of yarn or thread or a weight equivalent thereto of count number sixty
and mark and number such position upon the scale t-Having thus obtained the
points which indicate the numbers of yarns numbers sixty seventy and eighty
I then by calculation or by means of weights in a manner similar to that above
described find the position for the remaining numbers from sixty one to sixty nine
both inclusive and from seventy one to seventy nine both inclusive and mark and
number them upon the scale t
I will now proceed to describe the manner in which the apparatus above
described is employed for ascertaining the counts of yarns or threads-Having
obtained two leas of the yarn or thread of which it is desired to ascertain the
count, it being known that such count is between numbers sixty and eighty.
suspend such yarn or thread upon the hook O and I then slide the weight z
longitudinally upon the arm C of the scale beam until the finger varrives
opposite the centre division of the scale was shown in the drawing then if the
yarn or thread is of count N° 70 the pointer will be opposite to the graduation
numbered seventy on the plate t but if such yarn or thread is finer than count N° 70
the weight z will have been slidden towards the left hand end of the scale upon
the plate t but if the said yarn or thread be coarser than count N° 70 the weight z
will have been slidden towards the right hand end of the scale upon the plate t the
position of the weight upon the scale beam indicating by the finger the
number or count of the yarn or thread-In order that the apparatus above
described may be employed to ascertain the numbers or counts of yarns or threads
of a great variety of numbers without employing a scale beam of inconvenient
length or a scale having graduations inconveniently close together or an incon-
venient number of loose weights y. z I use a series of separate plates or scales t¹.
t2t shown in Figs: 5. 6. 7. 8. such scales t¹ 2 3 being formed of sheet metal or
other suitable material and being provided with holes 1. 2. such holes corresponding
respectively to pins 3. 4 projecting from the plate t upon which the said plates or
scales t¹. may be placed-The scales or plates t¹. t. 3 are provided with
graduations marked thereon which represent the numbers or counts of yarn or
thread from 80s to 140s both inclusive, the scales or plates t¹ t t having been
graduated in a similar manner to the plate t previously described-I also employ
other weights y¹ y³y shown respectively in Figs: 9. 10. 11 which when in use are
placed upon the flange q and weights .. 26 shown respectively by Figs 12. 13. 14
which when in use are placed upon the arm C of the scale beam the weights y'. 24
being used in conjunction with the plate t the weights y with the plate and
the remaining weights y³ z in conjunction with the plate 3-The scales t¹ t² t³
with the scale t attached to the bracket or pillar b include the numbers of yarns or
threads from sixty to one hundred and forty both inclusive It will be readily seen
that similar scales and weights may be employed for ascertaining the numbers
or counts of yarns or threads of numbers higher and lower than those above
referred to
When the apparatus is not in use the lever g is liberated and the rode and
parts j. k thereof upon which the centre m of the scale beam l rests will be lowered,
such lowering of the rode and the parts j. k will cause the scale beam / to be lowered
until projecting parts m' m² formed upon the ends of the centre m will rest upon
the projections c. d when the end 2 of the scale beam will be supported by the
lower end of the slot formed in the upright part 8
By using the apparatus above described I am enabled to ascertain the numbers
or counts of yarns or threads with greater ease and certainty than by the use of
any apparatus in use heretofore-I have hitherto referred to weighing yarns or
threads for the purpose of ascertaining the counts or numbers thereof but I would
have it understood that my Invention may also be employed for other purposes
such as indicating the value of a given weight or quantity of material or other
proportion of weight to length or value as for instance weighing letters to ascertain
the amount of the postage therefor
