PROVEMENTS IN STOP MOTION WINDING DOUBLING FRAMES."

page_text: Letters Patent for the same, and have made solemn Declaration that
I, the said Thomas Unsworth, am the true and first Inventor thereof.
NOW KNOW YE, that I, the said Thomas Unsworth, do hereby
declare that the following Complete Specification, under my hand and
seal, fully describes and ascertains the nature of the said Invention, and
in what manner the same is to be performed in and by the following
statement:-
On the 30th day of September 1873, I lodged a Provisional Specifi-
cation of an improvement made by me in an Invention for "Self Stop
Winding Frames," for which Letters Patent were granted to me and
Edward Whalley on the 7th day of August 1871, Numbered 2077.
My present Invention consists of the before-mentioned provisionally
specified Invention with additional improvements and more perfect
arrangements for guiding the yarn by revolving guide pulley (taking
away the friction from very soft yarn or material), moveable drag boards
(to vary the tension of the yarn), revolving creel pegs (for winding from
the bobbin so made and arranged as to allow the winding of the softest
yarn that can be spun), guide wires fixed above the drag board (to
increase or decrease the drag or tension), a quadront or orther shaped
balance stop tip ended lever (being another mode of instant stopping
when an end breaks). This lever acts as a drag board as well as a stop
lever.
My improvements chiefly relate to "stop motion winding doubling
frames" having a detective apparatus to instantly stop the bobbin or
spool when a thread breaks or when the cop or bobbin runs empty.
.
Hereunto I annex a Sheet of Drawings in the several Figures of
which similar parts are marked by corresponding letters of reference.
Fig. 1 is an end view of frame shewing the two" self-stop motions" in
position, one on each side representing the two different modes of.
stopping; Fig. 2 is a side view of the same; Fig. 3, a plan; Figs. 4, 5,
6, 7, 8, 9, 10, 11, 12, and 13 are detailed parts necessary to the full
developement of my Invention.
A, A, is the frame of the machine; B, the stand board for carrying
the cops or bobbins; C, a board hinged on to board B, specially for

page_text: carrying bobbins, and so made as to be set at any desired angle for the
more easy off winding of the yarn ; D, bobbius and cops; E, friction eye
used when heavy tension is required (but not with soft yarn); F, breast
drag board; G, eyelet end of thread lever; H, a carrier bar bracket for
keeping up yarn from eyelet G; H¹, bracket for carrying same; I, taking
up bobbin; J, friction roller driving the taking-up bobbin by the friction
on the yarn as taken up, which tends to the more firmly laying of such
yarn on the bobbin; K, a double sided L lever; L, fulcrum bracket for
carrying the lever N, O; P, the tipping end of tread lever; Q, bracket
for carrying K, lever by fulcrum pin 2 at the knee; R, headstock for
carrying rod S for stopping the P end of thread lever from going too
high, and for carrying such thread levers by rod 3, Figs. 5 and 10; T, a
mangle wheel reversing motion for winding on take up bobbin; 4 is a
rod for communicating action from same to slide bar 5; U, is a guide
pulley for the more casily carrying the yarn to the take up bobbin when
the yarn is very soft and not strong enough to bear friction anywhere';
V is the end of a lever same as N, O, lever before mentioned, and used
for the same purpose in another mode of self-stopping, which is done by
the quadrant or other shaped lever W, X; Y is headstock for carrying
the same; Z, a breast board or front plate to carry them; 6, is the driving
friction roller running the whole length of the machine where any number
of take up bobbins may be arranged for on each side of the machine;
7, is a stop bar, against which the driven friction rollers driving take up
bobbins comes in instant contact on the dropping of the M end of L lever
K; a, is a jaw lever bracket fulcrummed by spindle 8 to the frame 9, which
carries roller or friction plate 6 to keep take up bobbin in its place, and
to assist in evenly laying the yarn on bobbins.
Having particularly described my Invention in detail, I will now
proceed to describe its actions.
Fig. 1 shews the two modes of applying my Invention. The yarn
passes on the left-hand side from the bobbins through tension eyelet E,
over breast drag board F (which I cover with flannel or cloth) over bar
H, and then through eyelet end of thread lever (which holds it up in
the position shewn) to take up bobbin I, which is driven by friction

page_text: When an end breaks the eyelet end G of thread lever falls down,
which being fulcrummed on to bar or stud 3, brings up P end of the said
thread lever, lifting the O end of the lever O, N, fulcrumed at a¹, of
bracket L, having a shelved leg b¹ immediately under fulcrum a'. While
the yarn is whole and winding the end M of double sided L lever K
rest upon the shelf of leg b', but when an end breaks the O end of the
O, N, lever is lifted by P, thus drawing the shelf of leg b¹ from under
M end of lever K, which falling brings over the upper end of L lever by
reason of its being fulcrummed at the knee, carrying thereby the driven
friction roller (carrying take up bobbin) from the driving friction roller
in instant contact with the front bar 7.
On the other or right-hand side of the same Figure 1 I have shewn
cops to wind from, which, if tension be required, I take the thread
through eyelet E round bar E¹ over quadrant or other lever W, X, and
over guide pully U to take up bobbin I, same as discribed on the other
side of frame.
When an end breaks the W end of W, X, quadrant or other shaped
lever falls, which being fulcrummed to bracket Y by pin X', lifting up X
end of such quadrent or other shaped lever on which rests V end of N
lever having a shelved leg b' fulcrumed and acted upon, same as the O, N, 1
lever described on the other side of the frame; Fig. 13 is an enlarged view
of this O, N, lever in detail; Fig. 11 is a yarn guide fixed on the slide
bar for guiding the yarn on to take up bobbins; Fig. 9 is guide pulley for
soft yarn, also fixend on slide bar, the one may be substituted for the
other to suit the yarn as required; Fig. 12 is a revolving creel peg fixed
into angle board C, off which to run the bobbins at any angle.
Having fully described my Invention and the ways I work it, I desire
it to be known that I do not confine myself to the precise details I have
had occasion to describe and refer to, as many variations may be made
without deviating from the principle or main features of my Invention,
but what I claim is,―
First. The double-sided L lever K, with its connections and actions
with frictions roller J and front stop bar 7, Fig. 4, substantialy as and
for the purpose herein-before set forth.,
Second. The friction roller b, Fig. 1 and 8, guide pully U, Fig. 9,
substantialy as and for the purpose herein before sot farth

page_text: Third. The quadrant or other shaped lever W, X, or any other modifi-
cation of the same, and the general arrangement of the several parts,
substantialy as and for the purposes herein-before set forth.
In witness whereof, I, the said Thomas Unsworth, have here-
unto set my hand and seal, this Sixth day of April, in the
year of our Lord One thousand eight hundred and seventy-
four.
