TO ALL TO WHOM THESE PRESENTS SHALL COME, we, SAMUEL
RICHARDS, of Nottingham, in the County of Nottingham, Cotton
Doubler, JOSEPH STUBBS, of Manchester, in the County of Lancaster,
Machine Maker, and JAMES GLOVER, of Nottingham aforesaid, Over-

WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Tenth day of June, in the year
of our Lord One thousand eight hundred and seventy-five, in the
thirty-eighth year of Her reign, did for Herself, Her heirs and suc-
cessors, give and grant unto us, the said Samuel Richards, Joseph
Stubbs, and James Glover, Her special license, that we, the said
Samuel Richards, Joseph Stubbs, and James Glover, our executors,
administrators, and assigns, or such others as we, the said Samuel
Richards, Joseph Stubbs, and James Glover, our executors, admini-
strators, 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 FOR DOUBLING AND WINDING YARNS OR THREADS OF COTTON AND
OTHER FIBROUS MATERIALS," upon the condition, amongst others, that
we, the said Samuel Richards, Joseph Stubbs, and James Glover, by an
instrument in writing under our hands and seals (or under the hand and
seal of one of us) should particularly describe and ascertain the nature
of the said Invention, and in what manner the same was to be
performed, and caused the same to be filed in the Great Seal Patent
Office within six calendar months next and immediately after the date of
the said Letters Patent.

page_text: NOW KNOW YE, that I, the said Joseph Stubbs, do hereby declare
the nature of our said Invention, and in what manner the same is
to be performed, to be particularly described and ascertained in and
by the following statement and accompanying Drawings, that is to
say:-
Our Invention relates, firstly, to an apparatus to be applied to
'doubling frames, whereby what are commonly called snarls and lashed
broken ends are avoided. This part of our Invention is shewn at Fig. 1,
which represents a section of a portion of a doubling frame. At 1, 2,
are the top and under rollers, over which two threads to be doubled are
conducted, as shewn by the red line, but each of these threads passes
over a roller 3, or its equivalent, which is carried by a spring 4, the
other end thereof being attached to the framework 5. Over this roller
the threads pass, as shewn by the red line, on their way to the flyer, and
by their tension slightly pull down the spring 4, which therefore exerts
a slight elastic force upon the said yarns, and by keeping them distended
prevents them from forming snarls; but, in addition to this result,
suppose one of the threads to break between the roller and the spindle,
then the reacting elasticity of the spring 4 will flirt up the portion of
the thread which is upon the roller 3, and prevent the broken end from
lashing with the other threads. It will be evident that a weight might
be substituted for the elastic force of the spring 4.
Another part of our Invention also includes the use of the aforesaid
roller 3 with its spring or weight over which the threads pass, the object
in this case being to break the remaining thread or threads at the back
of the machine, so as to prevent roller waste or yarn from passing on to
the bobbin. This part of our Invention is shewn at Figs. 2 and 3, the
course of the threads being as before indicated by the red line. In this
instance however we have shewn a weighted lever instead of the spring
before referred to. This lever is shewn at 6 carrying as before the
roller 3, over which the threads pass. The said lever is capable of turning
upon a center 7 carried by the framework, and at its end opposite to
that of the roller 3 carries an adjustable weight 8, by means of which
the tension upon the threads may be regulated. The lever 6 is provided
with a wedge-shaped cross piece 9, and upon the frame is a simlarly
formed cavity 10. The Drawing shews other parts, to which we shall
hereafter refer in connection with another part of our Invention.
When a thread breaks the lever 6 is released from tension, and then

page_text: turns upon the centre 7, by which means the part 9 passes into the
cavity 10, and clamps the remaining thread or threads, which being
then pulled forward by the rollers become broker..
Another part of our Invention is designed to prevent the lapping of the
material on the roller when an end breaks, and is shewn at Figs. 2 and 3
before referred to. Upon the lever 6 we place a roller 11 in contact
with the surface of the ordinary top roller 1. When therefore the said
lever 6 is pulled down by the tension of the yarn, as above described, the
roller 11 pressing against the said top roller 1 keeps it in its working
position, but when a breakage takes place, and the lever 6 turns upward,
then the roller 11 also passing upward allows the top roller 1 to run
downward, and in doing so it arrives upon an incline 13, which carries
it away from the surface of the bottom roller by the dotted line, and
the driving therefore ceases. Of course the spring 4 might take the
place of the lever 6, and although we have shewn the above-described
parts of our Invention combined they may be used separately if
desired.
Another part of our Invention refers to winding machines, in which
what are commonly called clearers are employed, and our object is so to
construct such clearers that when a knotty part occurs in the yarn or
thread the attendant shall not be able to lift it out of the clearer, and
allow it to pass. This improvement is shewn in two views at Figs. 4 and 5,
and also in the enlarged detached views, Fig. 6. At 15 is the ordinary
slit of the clearer formed by two adjustable parts 16, 17, to the former
of which is adapted a curl 18 projecting into a recess 19 formed in the
part 17. In adapting the yarn or thread it is passed down the slit 15 as
usual, and conveyed past the curl 18. If it be attempted to raise it
from that position, in order to lift it from the slit, it is guided to the
left-hand side of the curl, which then prevents it from passing any
further.
Figs. 7 and 8 represent a modification in construction. In this instance
20 is the ordinary sheet-metal clearer, the curl 18 being attached thereto
on one side of the slit 15, which curl is then enclosed by a casing 21
formed in two parts, and soldered or otherwise attached to the
clearer.
In Fig. 5 we have shewn a second clearer 23 adapted to the back of
that shewn at 16, 17, and this may be used in all cases if desired, the
better to secure the clearing of the yarn.

page_text: Having thus described and ascertained the nature of our said Inven-
tion, and the manner in which the same is to be performed, I desire it
to be understood that we claim as secured to us under the above in part
recited Letters Patent, and for the purposes above set forth,-
