CERTAIN IMPROVEMENTS IN MACHINERY OR APPARATUS FOR WARPING WORSTED, LINEN, COTTON, SILK, OR WOOLLEN YARNS
Year: 1838

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, DAVID
WILKINSON SHARP, of Bingley, in the County of York, Worsted Spinner, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Royal
Letters Patent under the Great Seal of Great Britain, bearing date at
Westminster, the Thirtieth day of January, in the first year of Her reign, did,
for Herself, Her heirs and successors, give and grant unto the said David
Wilkinson Sharp, Her especial licence, full power, sole privilege and authority,
that I, the said David Wilkinson Sharp, my executors, administrators, and
assigns, and such others as I, the said David Wilkinson Sharp, my executors,
administrators, and assigns, should at any time agree with, and no other,
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 FOR WARPING WORSTED, LINEN,
COTTON, SILK, OR WOOLLEN YARNS;" in which said Letters Patent is contained a
proviso, that I, the said David Wilkinson Sharp, shall cause a particular
description of the nature of my said Invention, and in what manner the same
is to be performed, and to cause the same 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.
NOW KNOW YE, that in compliance with the said proviso, I, the said
David Wilkinson Sharp, do hereby declare that the nature of the said Inven-

page_text: tion, and the manner in which the same is to be performed, is particularly
described and ascertained in the Drawing hereto annexed, and the following
explanation thereof, that is to say :-
My improvements in the machinery or apparatus for warping worsted, linen,
cotton, silk, or woollen yarns, consist in the adaptation of certain mechanism
to that part of warping apparatus called "the warping mill (that is, the reel or
cylinder upon which the yarn is to be wound), for the purpose of driving the
same and causing it to perform its necessary evolutions by power instead of
by manual labour, as heretofore practised. For the more perfect illustration
of my Invention, I have attached to these Presents a Drawing of an ordinary
warping apparatus, with my improvements applied. In Figure 1, a, a, a, is the
creel supporting the bobbins b, b, b, from which the thread or yarns proceed to
the frame c, c, called the "jack," or "heck," where the yarns are adjusted and
laid in the proper order, by passing through the eyes or guides with which this
frame is furnished; the threads or yarns are hence conducted to the warping
mill or reel d, d, upon which they are to be finally wound. This cylinder or
warping mill (which has formerly been worked by hand) is now driven by an.
alternate rotary motion, by means of the driving apparatus exhibited above.
Upon the horizontal shaft e, e, there is a conical drum f, which receives motion
through the strap 9 passing from a similar drum upon the line shafting of the
warping room. There is a bevilled pinion h upon the shaft e, which is placed
between the two bevilled wheels i, i, fixed upon the vertical shaft k, but so
arranged that the pinion shall be in gear with but only one of the bevilled
wheels at a time. Supposing now the bevilled pinion h to be in gear with the
lower bevil wheel i, it will be seen that if a cord or band be passed from the
pulley upon the vertical shaft k to the pulley m upon the shaft n, carrying.
the reel or warping mill, the mill will be made to revolve in one direction,.
and the yarns to be successively wound upon it heliacally from the top to
bottom as the jack descends, and as it rises to wind the threads upon the mill
the reverse way. To preserve their continuous lengths, the yarns must be
passed round the pin with which the warping mill is usually provided, and the
mill caused to wind on the yarn from bottom to top, by throwing the bevil
pinion into contact with the upper bevilled wheel i, which will necessarily
drive the warping mill in the opposite direction. The "jack" or "heck"
frame is provided with a handle or lever o, for the purpose of throwing the
bevil pinion h in and out of gear with the bevel wheel i; this lever must of
course be suitably attached to the shaft which carries the bevilled roller h,
and by shifting the handle o from the notch p to the notch 9 in the jack frame,
the bevilled gearing may be regulated as required, or by placing it in the
เ

page_text: centre notch r, the whole may be put out of geer, and the warping mill
allowed to be at rest. It will be seen in Figure 2 that I propose to employ
bevilled wheels or pullies with plain friction surfaces only instead of gearing,
the surfaces being covered with leather, and this mode of driving I prefer
as being more readily adjusted.
Having now described my improvements, and the manner in which they are
to be performed, I wish it to be understood that I claim as my Invention, the
driving of mills or reels for warping yarns by power, and by means of similar
apparatus to that above described and represented in the Drawing attached.
In witness whereof, I, the said David Wilkinson Sharp, have hereunto
set my hand and seal, this Fourth day of June, in the year of our
Lord One thousand eight hundred and thirty-eight.
DAVID WILKINSON (L.s.) SHARP.
AND BE IT REMEMBERED, that on the Fourth day of June, in the first
year of the reign of Her Majesty Queen Victoria, the said David Wilkinson
Sharp came before our said Lady the Queen in Her Chancery, and acknow-
ledged the Instrument aforesaid, and all and every thing therein contained
and specified, in form above written. And also the Instrument aforesaid
was stamped according to the tenor of the Statute made in the fifty-fifth year
of the reign of His late Majesty King George the Third.
