PROVISIONAL SPECIFICATION left by the said George Hewitson
at the Office.of the Commissioners of Patents, witli his Petition,
on the 5th February 1853.
I, GEORGE HEWITSON, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN MACHINERY OR APPARATUS FOR MEA-
SURING OR INDICATING THE LENGTH OF YARN AS IT IS SPUN OR WOUND ON
BOBBINS OR ROLLERS" to be as follows:-
My Invention relates to a method of ascertaining the quantity or
length of yarn spun by cach spinning machine, or wound on bobbins
or rollers. I accomplish by fixing an indicator in any convenient
position on the spinning frame, to be worked from the drawing
rollers, or on machines or apparatus used for winding or warping,
and consists of two worm wheels upon the same centre, and worked

page_text: by the same worm; one of the said wheels to have 59 teeth, and the
other 60, the under wheel having an index in an opening and finger
in the upper wheel of 59 teeth, showing the numbers. The advan-
tages of this indicator consist in its giving a correct estimate of the
quantity of yarn spun or wound in any given length of time, thus
giving a stimulus to the hands employed; and the index having to
revolve only about 30 times a week, its durability will be almost
incalculable.
I desire it to be understood that this is merely an outline de-
scription of my said Invention, which will be more fully explained
in my Complete Specification.
SPECIFICATION in pursuance of the conditions of the Letters
Patent, filed by the said George Hewitson in the Great Seal
Patent Office on the 5th August 1853.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I,
GEORGE HEWITSON, of Bradford, in the County of York, Machine
Maker, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Royal Letters Patent, bearing date the Fifth day of February, in
the year of our Lord One thousand eight hundred and fifty-three, in
the sixteenth year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said George Hewitson, Her
especial license that I, the said George Hewitson, my executors, ad-
ministrators, and assigns, or such others as I, the said George Hewitson,
my executors, administrators, and assigns, should at any time agree
with, and no others, from time to time and at all times thereafter
during the term therein expressed, should and lawfully might make,
use, exercise, and vend, within the United Kingdom of Great Britain
and Ireland, the Channel Islands, and Isle of Man, an Invention for
"IMPROVEMENTS IN MACHINERY OR APPARATUS FOR MEASURING OR INDI-
CATING THE LENGTH OF YARN AS IT IS SPUN OR WOUND ON BOBBINS OR
ROLLERS," upon the condition (amongst others) that I, the said George.
Hewitson, by an instrument in writing under my hand seal,.

page_text: should particularly describe and ascertain the nature of the said In-
vention, and in what manner the same was to be performed, and
cause the same to be filed in the Great Seal Patent Office within six
calendar months next and immediately after the date of the said
Royal Letters Patent.
.
NOW KNOW YE, that I, the said George Hewitson, do hereby.
declare the nature of my said Invention, and in what manner the
same is to be performed; to be particularly described and ascertained.
in and by the following statement (that is to say):
My Invention relates to an improved method of ascertaining or
registering the quantity or length of yarn spun by each spinning.
machine, or wound on bobbins or rollers by other machines, which:
I accomplish by fixing an indicator of peculiar construction in 'any.
convenient position on the spinning frame, or on machinery or:
apparatus used for winding, warping, or other similar purposes.;
This indicator or apparatus consists of the arrangement or working
of two worm wheels or tangent wheels upon the same centre, and,
worked by the same worm; one of the said wheels having fifty-nine.
teeth, and the other sixty, the under one being provided with an
index which shews in an opening of the top one, and a finger fixed
to the upper wheel of 59 teeth shews or indicates the quantity of
yarn spun or wound. The said worm is fixed on a vertical rod or
shaft, which revolves, and thus turns the tangent wheels, and on
the top of the said vertical rod is fixed a pinion, which receives
motion from another wheel or pinion driven by the machinery; for
instance, in spinning it is driven from the drawing roller shaft, the
teeth in the said wheel being so' calculated that for every sixty re-
volutions the worm turns the inner tangent wheel one tooth, and
thus moves only one figure of the index. The advantages of this:
indicator consist in its giving a correct estimate of the quantity of
yarn spun or wound in any given length of time, giving thereby a
stimulus to the hands employed, and enabling the master to ascer-
tain the quantity produced by each machine; and the index having
to revoke-only about thirty times a week, its durability will be
almost incalculable. This improved apparatus will be easily under-

page_text: stood by reference to the accompanying Sheet of Drawings, in which
the same letters of reference are used to represent similar parts,
where different views or diagrams are shewn. Fig. 1, represents a
front elevation; Fig. 2, a side elevation; Fig. 3, a plan; and Fig. 4,
a view of the inner tangent wheel. a, represents the bottom wheel
of sixty teeth; b, the top one of fifty-nine teeth; c, the finger or
indicator; and d, the worm; e, the pinion, which is worked from the
roller of the spinning frame, or from a similar power in other
machines, to which this indicator is applicable.
Having thus described the nature and particulars of my said In-
vention, I desire it to be distinctly understood that I do not confine
myself to the exact details herein described, nor to the precise
number of teeth in the tangent wheels, as such may be varied or
modified without departing from the principle thereof. But I claim
as of my Invention, and which to the best of my knowledge and
belief has not been hitherto used within this realin, the construction
of an indicator as herein described applicable to the measuring of
yarns or thread as it is spun or wound.
In witness whereof, I, the said George Hewitson, have here-
unto set my hand and seal, this Fourth day of August, One
thousand eight hundred and fifty-three..
GEORGE HEWITSON. (L.S.)
