PROVISIONAL SPECIFICATION.
Improvements in Balance Apparatus for Ascertaining Counts or
Numbers and Weight of Yarn..
I, GEORGE THOMAS, of the firm of George Thomas & Co., of 28, Deansgate,
Manchester, in the County of Lancaster, Engineer, do hereby declare the nature
of this invention to be as follows:-
My invention relates to improvements in Staub's Yarn Assorting Balances of
the type described in the Specifications to Letters Patent Nos. 6703 of 1886 and
15454 of 1889.
The yarn assorting balance constructed according to my improvements consists
of a standard or pedestal mounted upon a tripod. One of the feet of the tripod is
provided with an adjusting screw by means of which the balance can be adjusted to
its proper position which is indicated by a finger or pointer on a pendulum pivoted
to the pedestal as in the original forms of the balance.
Upon the beam or balance arm, which is fulcrumed on the pedestal as before, I
employ on one side a sliding finger from which a hook depends, and on the other
side two sliding fingers or pointers both without hooks but each equal in weight to
the sliding finger and hook.
A plate provided with several horizontal rows of graduated lines forming scales
is secured to the pedestal parallel to and behind the beam. The narrow part of
this scale, or that corresponding to the side of the beam upon which the sliding
finger and hook is mounted, has only one graduated line indicating counts from 60
to 432 whilst on the other side of the beam the scale has three graduated lines; the
first is similar to that on the narrow part of the scale, another indicates the counts
of the yarn tested from Nos. 10 to 100 and the third is graduated to enable very
light objects varying from say 4 to 14 grains to be weighed.
To ascertain the correctness of the balance the sliding finger with the hook is
moved opposite number 140 on the count graduation and the other sliding fingers
opposite numbers 216 and 432 respectively of the corresponding count graduation,
the beam must then balance.
After having measured the yarn to be tested remove the sliding finger and hook
to that number of the graduation which is equal to the length of thread expressed
in inches, z. if 60 inches of yarn are tested place the finger opposite number 60
and then hang the yarn on the hook. One of the sliding fingers on the other side
is moved so that it indicates the saine number or count on the first graduation so as
to balance the weight of the finger with its hook. Afterwards slide the third finger
until the beam balances then the number indicated by it on the second graduation
gives the exact count or yarn number.
The balance arranged as above described is intended to be used for testing cotton
yarns but by adjusting the relative weights of the fingers it can also be used for yarns
of woollen worsted linen jute etc.
To ascertain the weight of a light object from 4 to 14 grains place the first finger
and hook opposite 216, and the third finger opposite 252.and slide the second finger
until the beam balances. The count indicated by the second finger on the middle
graduation gives the weight in grains.

Improvements in Balance Apparatus for Ascertaining Counts or
Numbers and Weight of Yarn.
I, GEORGE THOMAS, of the firm of George Thomas & Co., of 28, Deansgate,
Manchester, in the County of Lancaster, Engineer, 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:-
My invention relates to improvements in Staub's Yarn Assorting Balances of
the type described in the Specifications to Letters Patent Nos. 6703 of 1886 and
15454 of 1889.
And in order that my invention may be fully understood and readily carried into
effect I will describe the accompanying sheet of drawings reference being had to the
figures and letters marked thereon.
Figure 1 is a side elevation Fig. 2 a plan and Fig. 3 an end elevation of a yarn
assorting balance constructed according to my invention.
The improved balance as now constructed consists of a standard or pedestal a
mounted upon a tripod. One of the feet of the tripod is provided with an
adjusting screw e by means of which the balance can be adjusted to its approximately
correct position which is indicated by a finger or pointer d' on a pendulum d pivoted
at a to the pedestal a as in the original forms of the balance.
Upon the beam or balance arme which is fulcrumed on the pedestal as before, I
employ on one side a sliding finger from which a hook depends, and on the other
side two sliding fingers or pointers g, h, both without hooks but each equal in weight
to the combined weight of the sliding finger and hook ".
A plate provided with several rows of graduated lines forming scales is secured
to the pedestal a parallel to and behind the beam e. The narrow part of this scale i,
or that corresponding to the side of the beam upon which the sliding finger with
the hook is mounted, has only one graduated line indicating inches from 60
to 432; whilst on the other side of the beam e the scale has three graduated lines;
the first, the top line, is similar to that on the narrow part of the scale, another, the
bottom line, indicates the counts of the yarn tested from Nos. 10 to 100, and the
third, the middle line, is graduated to enable very light objects varying from say 4
to 14 grains to be weighed.
To ascertain the correctness of the balance the sliding finger with the hook '
is moved opposite number 140 on the count graduation and the other sliding
fingers g, h, opposite numbers 216 and 432 respectively of the corresponding count
graduation; the beam e should then balance, as the apparatus has been approxi-
mately adjusted by the adjusting screw c; but if it does not it must be made to do
so by again turning the said screw c.
After having measured the yarn to be tested move the sliding finger and hook
to that number of the graduation which is equal to the length of thread expressed
in inches, viz., if 60 inches of yarn are tested place the fingerf opposite number 60
and then hang the yarn on the hook . One of the sliding fingers g, h, on the
other side is moved so that it indicates the same number on the first or inch
graduation so as to balance or compensate for the weight of the finger with its
hook. Afterwards slide the third finger until the beam e balances, then the
number indicated by it on the second graduation gives the exact count or yarn
number.
Though the inch graduation only begins with 60 inches yarns of shorter lengths
down to a few inches can be tested. Also coarse yarns from Nos. 1 to 10 as well
as fine yarns from Nos. 100 to 400 can be assorted with equal facility by this
balance by simply taking relatively shorter lengths of coarse yarns and longer
lengths of fine yarns.

page_text: The balance arranged as above described is intended to be used for testing cotton
yarns but by adjusting the relative weights of the fingers it can also be used for
yarns of woollen, worsted, linen, jute, etc.
To ascertain the weight of a light object from 4 to 14 grains place the first
finger and hook f' opposite 216, and the third finger h opposite 216 and slide the
second finger g until the beam balances. The number indicated by the second
finger g on the middle graduation gives the weight in grains.
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 :-
In a yarn assorting balance-
1. The beam or balance arm e furnished with a sliding finger and hook on one
side of its fulcrum, and on the other side with two sliding fingers each equal in
weight to the first finger and hook in combination with the graduated plate i
substantially as and for the purposes described with reference to the drawings
annexed.
2. The combination with the beam or balance arm e fulcrumed on a standard or
pedestal, of the tripod and an adjusting screw c substantially as and for the
purpose specified.
3. The combination and general arrangements of the parts as shown and
described.
