page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
KENWORTHY, of Blackburn, in the County of Lancaster, Cotton Spinner, send
greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Letters Patent under the Great Seal of Great Britain, bearing date at
Westminster; the Eleventh day of March, One thousand eight hundred and
forty-three, in the sixth year of Her reign, did, for Herself, Her. heirs and
successors, give and grant unto me, the said William Kenworthy, Her espe-
cial licence, full power, sole privilege and authority, that I, the said William
Kenworthy, my executors, administrators, and assigns, and such others as
I, the said William Kenworthy, my executors, administrators, or assigns,
should at any time agree with, and no others, from time to time and at all
times during the term of years therein expressed, should and lawfully might
make, use, exercise, and vend, within England and Wales, and the Town of
Berwick-upon-Tweed, my Invention of "CERTAIN IMPROVEMENTS IN MACHINERY
OR APPARATUS CALLED BEAMING OR WARPING MACHINES;'" in which said
Letters Patent is contained a proviso that I, the said William Kenworthy,
shall cause a particular description of the nature of my said Invention,
and in what manner the same is to be performed; to be inrolled in Her
Majesty's High Court of Chancery within six calendar months next and
immediately after the date of the said in part recited Letters Patent, as
in and by the same, reference being thereunto had, will more fully and at
large appear.

page_text: NOW KNOW YE, that in compliance with the said proviso, I, the said
William Kenworthy, do hereby declare that the nature of my said Invention,
and the manner in which the same is to be performed, is particularly
described and ascertained in and by the Drawings hereto annexed, and the
following explanation thereof, that is to say :-'
My Improvementsin Machinery or Apparatus called "Beaming orWarping
Machines," relate particularly to machines so called or known, and now com-
monly employed in cotton and other woven manufactures for the purpose of
beaming or warping" the threads or yarns, that is, winding them upon
a roller or beam from the bobbins upon which they have been spun, prior
to their being stiffened or dressed preparatory. to placing them in the loom
for weaving, wherein they are intended to constitute the warp, threads, or
yarns.
These improvements consist, firstly, in the application of suitable mecha-
nism to the ordinary beaming or warping machine, for the purpose of
reversing the motion of the beam or roller, upon which the yarns are being
wound by power in the event of a thread or yarn breaking, in order that the
broken ends may be readily found, and again united or tied up, to make the
warps or yarns perfect, this necessary reversing of the beam or roller having
hitherto been done by the hands of the workman, and with a considerable
expenditure of time and labor. And
Secondly, these improvements consist in the application and arrangement
of other suitable mechanism to be used in the said machines, either in con-
junction with the said reversing apparatus, or separately. and unconnected
therewith, for the purpose of" taking up the slack," or preserving the tension
of all the unbroken threads which would otherwise be left loose between the
beam and the bobbins (as the beam is reversed) whilst the unbroken threads
are being tied up. This requisite operation has also hitherto been performed
by the hands of the operator, and is by the present improvement accomplished
by self-acting machinery. As the "beaming or warping" machine, its ope-
ration and use, is well understood by persons conversant with the manufacture
of woven fabrics, it is only necessary for me to describe the application of
any improvements, and their mode of operation, in connection with such
machines.
Having now described the nature and object of my Invention, I will pro-
ceed to exhibit the manner in which the same is to be performed; for which
purpose I have attached to these presents a Sheet of Drawings representing,
in several views, an ordinary beaming or warping machine (drawn at about
one-eighth the real scale), with my improvements applied or attached thereto,

page_text: and which parts are particularly distinguished by being shaded with color,the
common parts of the apparatus being drawn in outline only.
DESCRIPTION OF THE DRAWING.
Figure 1 is a plan or horizontal view of a warping or beaming machine, as
seen from above; Fig. 2, a front elevation; Fig. 3, an end view; Fig. 4, a
transverse section; and Fig. 5, a longitudinal section, both taken vertically
through the machine. The framing a, a, a, a, supports the reed b, b, the dis-
tending rollers c, c, c, and the tension rods and wires d, d, d, d, over which the
warps, yarns, or threads e, e, e, e, pass as they proceed from the creel of
bobbins behind (not shewn in the Drawing). These warps, yarns, or threads
pass onwards to be wound upon the beam or roller f.f, ready for the sub-
sequent processes of dressing and weaving. The roller or beam f, f, is caused
to revolve and wind on the yarn by friction of contact with the bed or bottom
roller g,g, on which it bears, this roller being driven by means of the ordinary
driving strap passing around the fast pulley i upon the roller shaft h. In
the event of any one or more of the warps, yarns, or threads e, e, breaking in
their passage from the bobbins to the yarn beam, my improvements come into
effect as follows:-Upon the discovery of a broken thread the workmau
instantly turns (towards the left hand) one of the handles l, l, which are fast
upon the upper end of the vertical shafts m, m; and upon the lower ends of
these shafts there are toothed segments n, n, taking into the racks o, o,
formed upon the cross shaft p.p. To the extremities of this shaft strap guides.
or forks q, q, are attached, which, on the handle / being turned, instantly passes
the driving strap hon to the loose pulley, and at the same time passes another
reverse or crossed driving strap on to the fast pulleys at the other end of the
roller shaft :, and immediately causes that roller, and with it the winding-on
beam f to turn in the reverse direction, and thus give back the threads until
the ends of the broken yarn or thread are tied up, so that the warping or
beaming may proceed. Now, at this time it will be seen that as all the
threads are loosened by the reversing of the rollers f and y, it is necessary to
"take up the slack" of the yarns, or preserve their tension and order whilst
the broken thread is being repaired. For this purpose the cross rods t, t, t, t,
lying over the yarns, are provided, being similar to those in common use,
excepting that these have small rollers upon their ends (bearing on the two
side rails y*), and are made to lower themselves by self-acting means instead
of being supplied by hand, as in common. As the handles l, l, are turned for
reversing the beam or roller, small cams or excentrics u, u, upon the upright

page_text: shafts m, m, shift the levers v, v, slightly working on their fulcrums w, w, the
ends of which, by catching against the hooked end of the sliding frames
yyyy, shift these frames just sufficient to allow the first tension rod t' to
pass over the rounded end of the top or supporting rails y*, and thus to
descend in its grooves, falling to the bottom and preserving the tension of
the threads. The sliding frames y, y, run outwards on the rollers 1, 1, äs
shewn in red lines, allowing as many of the rods t, t, t, t, to fall in their
grooves,, as the slack of the yarn requires; that is, the longer time the
broken yarn is in being repaired, the greater is the amount of slack to be
taken up, and consequently the number of rods to be lowered, one of which
escapes the ends of the rails y* as it slides outwards, being gently pushed by
the falling rod running down its respective groove z, and bearing against the
vertical rail y of the sliding frame. The broken thread being repaired, the
straps and pullies are again reversed, and the yarn or warp beam caused to
turn in the direction for winding on, when the yarns as they tighten up will
raise the tension rods t, t, into their former position, and the counterbalance
weights and chains 2, 2, passing over the pulley 3, 3, and attached to the
sliding farmes y,y, will draw these frames backwards again into their former
position, the upper rail y passing under the rollers on the end of the tension
rods t, t, t, t, and supporting them until they may be again required.
Having thus described the nature of my said Invention, and the manner in
which the same is to be performed, I would remark, in conclusion, that any
reversing motion may as readily be applied for the purpose of enabling the
workman to reverse the action of the yarn or warp beam, as that of the crossed
and open strap above described, as those used in ordinary slide lathes, &c., which
will be evident to any competent mechanic. And also that the action of the
tension rods mayeither be employed in conjunction with such reversing motion,
or separately. But I claim as my Invention the reversing the action of the
yarn or warp beam by power, and the mechanism for working and employing
the rods for preserving the tension of the yarns, threads, or warps in "warping
or beaming machines" when required, as above particularly described and set
forth, whether such improvements be used separately or conjointly.
In witness whereof, I, the said William Kenworthy, have hereunto set
my hand and seal, this Ninth day of September, in the year of our
Lord One thousand eight hundred and forty-three.
WILLIAM (L.s.) KENWORTHY.
