PROVISIONAL SPECIFICATION.
Improvements in Scutchers or Machines for Opening and Preparing
Cotton or other Fibrous Substances.
I WILLIAM NOTON 93 Windsor Road Oldham Lancashire Cotton Spinner do
hereby declare the nature of this invention to be as follows:-
My invention relates to scutchers or machines for opening and preparing cotton
or other fibrous substances and consists in an arrangement of that part of the
scutcher or opening machine known as the piano motion. The piano motion
consists of a set of levers which placed under one of the feed rollers indicates
the thickness of the cotton or fibrous substance passing into the machine. To
get the average thickness of the cotton or fibrous substance I hang from the
indicating levers a number of levers in such a manner that by coupling them
together in several series I reduce them at last to one from which by other levers
the strap on the cones is operated to rise and fall. To facilitate the free play of
the hanging levers I use in one way knife edges as in weighing machines and double
links to connect the levers.

COMPLETE SPECIFICATION (AMENDED).
Improvements in Scutchers or Machines for Opening and Preparing
Cotton or other Fibrous Substances.
I, WILLIAM NOTON, of 93, Windsor Road, Oldham, in the County of
Lancaster, Cotton Spinner, 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 scutchers or machines for opening and
preparing cotton or other fibrous substances and consists in an arrangement of relates
to that part of the scutcher or opening machine known as the piano motion. The
piano motion consists of a set of levers which placed under one of the feed rollers
indicates the thickness of the cotton or fibrous substance passing into the machine.
To get the average thickness of the cotton or fibrous substance, hang from the
indicating levers a number of levers in such a manner, that by coupling two together
in several series, I reduce them at last to one, from which by other levers the strap
on the cones is operated to rise and fall.
To facilitate the free play of the hanging levers 1 use in one way furnish the
same with knife edges, as in weighing machines and use double links to connect the
levers.
And in order that my invention may be more fully understood I have caused to be
appended hereunto one sheet of drawings marked with letters of reference indicating
like parts in the various figures.

page_text: Figs. 1 & 2 are end views and Fig: 3 a sectional side view of my improved piano
motion as applied to a scutcher.
a are the cones of the piano feed motion, bis the strap fork, c are the indicating
levers, and d the feed rollers.
In carrying out my invention and referring to the figures generally, I suspend
from the free ends of each pair of indicating levers c, by means of hooks and eyes,
or otherwise, a link lever e. The series of levers e thus formed, I couple in pairs
by means of links to a second series e', these to a third series e and the latter to
one lever e only.
From the lever 3 is suspended, by means of the rod, made adjustable in length,
the rocking lever h, having its knife edged fulcrum on the block which is vertically
adjustable on the bracket A, secured to the framework of the scutcher. The free
end of the rocking lever is provided with a weight and connected by means of
the rod m to another lever, fixed on the shaft o, mounted in suitable bearings o
on the side of the frame work of the scutcher. Another lever p is fixed on the
shaft o, the free end of which is connected to the strap fork of the feed cones a by
means of the chain p¹.
By preference I form the fulcrums of all the links and levers described knife
edged, so as to minimize friction and thus ensure a free play:
The action of the levers described, is as follows:-
When the amount or thickness of fibres fed between the indicating lever cand the
feed roller d, is above that desired, the free end of one or more of the indicating
levers c ascends and pulls with it the end of the link lever é connected thereto, the
other end thereof serving as a fulcrum, see Fig. 2: This motion by means of the
links: and knife edges is then communicated in a like manner to the remainder of
the series of levers e¹ & e² and finally to the lever which raises the rocking lever h
and the latter by medium of the rod g,.lever p, shaft.o, chain.p', allows the strap.
fork b to rise and fall and thus increase or decrease the speed of the feed rollers d
according to the amount of fibres passing between the same.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed,. 1. deelare-that wish it to
be understood that I do not claim the suspension of a series of levers e e¹ e² e³ from the.
indicating levers c operating the cone strap fork b, but what I claim is-
"In piano feed motions for scutchers or. machines for opening and preparing
cotton or other fibrous substances."
1st. The general arrangement and combination of parts, operating substantially
as and for the purpose set forth.
2nd. The combination with the cone strap fork band indicating levers c, of a
number of levers e, suspended in such a manner from the indicating levers c, that by
coupling two together in several series e¹, e², they become reduced to one e³, from
which, by the medium of other levers, such as h, n, the strap fork is operated,
,substantially as and for the purpose set forth.
Dated this 2nd day of July 1891.
