IMPROVEMENTS IN SPINNING, DOUBLING, AND THROWING ORGANZINE SILK
Year: 1849

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, THOMAS
ROCK SHUTE, of Watford, in the County of Hertford, Silk Throwster, send
greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Royal Letters Patent under the Great Seal of the United Kingdom of Great
Britain and Ireland, bearing date at Westminster, the Fifteenth day of De-
cember (One thousand eight hundred and forty-nine), in the thirteenth year
of Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said Thomas Rock Shute, my exors, admors, and assigns, Her especial
licence, full power, sole privilege and authority, that I, the said Thomas Rock
Shute, my exors, admors, and assigns, or such others as I, the said Thomas
Rock Shute, my exors, admors, 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, Wales, and the Town of Berwick-upon-Tweed, my Invention of
"IMPROVEMENTS IN SPINNING, DOUBLING, AND THROWING ORGANZINE SILK;" in
which said Letters Patent is contained a proviso that I, the said Thomas Rock
Shute, shall cause a particular description of the nature of my said Invention,
and in what manner the same is to be performed,, by an instrument in writing
under my hand and seal, to be inrolled in Her Majesty's High Court of Chan-
cery 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
Thomas Rock Shute, do hereby declare that the nature of my said Invention,
and the manner in which the same is to be performed, are fully described and
ascertained in and by the following statement thereof, reference being had to
the Drawings hereunto annexed, and to the figures and letters marked thereon,
that is to say:-
My Invention consists of improvements on machinery now in use for
spinning, doubling, and throwing organzine silk. And in order that my
Invention may be fully understood and readily carried into effect, I will pro-
ceed to describe the means pursued by me.
DESCRIPTION OF THE DRAWINGS.
Figure 1 shews a front view of so much of machinery used for spinning,
doubling, and throwing silk, as will enable me to describe my improvements.
Figure 2 shews a transverse section of the same parts. a, a, are two
spindles, with bobbins b, b, on which is wound raw silk; and the requisite spin
is put thereon by motion communicated by straps or bands to the spindles a, a,
as heretofore. The separate ends of raw silk, from the two spindles a, pass
through the apparatus for equalizing the tension of the two threads, and such
apparatus also serves to break the second raw thread, should one of them have
been previously broken by any cause. This part of the apparatus and its
mode of working was fully described in the Specification of: my former Patent.
The two ends of raw silk pass around the bent stem c, which is of glass, and
thence over the wheel or pulley d, which is grooved, and also made rough, so
as, when aided by the india-rubber wheel f, to obtain a holding of the silk, in
order that the doubled silk may be prevented slipping and be drawn up
thereby at a regulated speed, depending on the rate at which. motion is com-
municated to the axis of the wheel d by the toothed wheel e, which is driven
by a cog wheel in the ordinary manner. f is another wheel or pulley, having
a hoop or band f¹ of india-rubber, vulcanized or prepared, as is now well under-
stood, so as not to be prejudicially acted on by heat and cold. The pulley or
wheelf is borne constantly down by a suitable spring 9, the frame h (which
carries the axis of the wheel or pulley) moving on an axis to allow of the
wheel or pulley f being raised from contact with the wheel d, when necessary
to pass the doubled silk between the wheels or pulleys d and f. The doubled
silk then passes over the bent stem i, which is of glass, and thence down to
the fly of the throwing spindle j, which throws the doubled silk, and also winds
it on to a bobbin k, such bobbin being caused to rise and fall in the manner
heretofore practised.

which the same is to be performed, I would have it understood that I do not
confine myself to the details as shewn and described, so long as the peculiar
character of any part of my Invention be retained. But what I claim is,
the application of the parts f, f, and g, acting with the part d, as described.
In witness whereof, I, the said Thomas Rock Shute, have hereunto set
my hand and seal, this Twelfth day of June, in the year of our Lord
