PROVISIONAL SPECIFICATION.
Improvements in Balance Apparatus for Ascertaining Counts or
Numbers and Weight of Yarn.
I, GEORGE THOMAS, of the firm of George Thomas and Co. of 28 Deansgate,
Manchester in the County of Lancaster, Engineer, a communication to me from
abroad by Emil Staub, of Emilienstrasse, 2, Leipzig, in the Empire of Germany,
Spinner, do hereby declare the nature of this invention to be as follows:-
This invention is chiefly applicable to those yarn balances for which Letters Patent
No. 6703 were granted to Henry Bernoulli Barlow (a communication to him from the
said Emil Staub) on the 19th May 1886.
In carrying out this invention I attach to the stand of the yarn balance a plate
preferably of metal on which is fitted an adjustable sliding piece provided with several
horizontal rows of graduated lines forming scales for the different yarns of which the
counts are to be ascertained.
The balance apparatus is made preferably as described in the Specification above
referred to with certain additions notably that of a sliding weight upon the beam.
which weight acts also as a pointer or indicator to the graduated scales.
The yarn to be tested or weighed must be accurately measured, it matters not
whether it be in one length or several short lengths say taken from a small sample of
cloth; the yarn is then put on the hook at one end of the beam the scale being in
position for the class of said yarn the sliding weight is now moved along the beam
until the latter is parallel with the horizontal arm of the balance the pendulum being at
rest in its normal position. The length of the yarn in millimetres is then divided by
the number indicated by the sliding weight and the result is the number of the count
of yarn.
For instance, suppose the length of yarn to be 2400 m/ and the
sliding weight to point to 60 on the scale then 100 = 40) and this will be the number
of the count of the yarn.
00
This method for ascertaining the counts of yarn is the same for yarns of all fibre
excepting silk; with silk on the contrary the number on the scale has to be divided
by the length of the yarn to obtain the number of the yarn.
In combination with the balance and scale I propose to employ a short rule say
10 centimetres long on which yarn or rovings can be carefully wrapped to form
a small skein which is then ready to be-placed over the hook.
Although I have described the measuring scale as in millimetres a different scale
might be employed.
In cases where the count of a very short light length of yarn is to be ascertained I
propose to employ auxiliary weights representing say five or ten times the weight of
the yarn and I place this weight on the hook in order to obtain a more accurate
result.

page_text: 10 centimetres long on which yarn or rovings can be carefully wrapped to form a

Although I have described the measuring scale as in millimetres a different scale
or measure might be employed.
In cases where the count of a very short light length of yarn is to be ascertained I
propose to employ auxiliary weights representing say five or ten times the weight of
the yarn and I place this weight on the hook in order to obtain a more accurate
result.
Having now particularly described and ascertained the nature of this said invention
as communicated to me by my foreign correspondent and in what manner the same is
to be performed I declare that what I claim is :-
The herein described improvements in yaru testing balance apparatus consisting of
the use and application of an adjustable plate provided with a number of scales for the
different yarns to be tested in combination with a single hook and a sliding weight on
the beam or balance arm all substantially as specified.
