IMPROVE- Dame Tu DomPLING WOOL AND OTHER FIBROUS SUBSTANCES
Year: 1853

page_text: LETTERS PATENT to Frederick William Mowbray, of Bradford, in
the County of York, Engineer, for the Invention of "IMPROVE-
Dame Tu DomPLING WOOL AND OTHER FIBROUS SUBSTANCES."
Sealed the 29th September 1853, and dated the 2nd April 1853.
PROVISIONAL SPECIFICATION left by the said Frederick William
Mowbray at the Office of the Commissioners of Patents, with his
Petition, on the 2nd April 1853.
I, FREDERICK WILLIAM MOWBRAY, of Bradford, in the County of
York, do hereby declare the nature of the said Invention for "IM-
PROVEMENTS IN DOUBLING WOOL AND OTHER FIBROUS SUBSTANCES" to be as
follows:-
The Invention consists in supporting the bobbins from which the
yarns are being drawn, to form a thread in a frame upon a spindle or
axis, to which rotary motion is given in such manner that twist may
be put on the yarn before it passes under the rollers, in addition to the
twist put on by the flyer.

page_text: SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Frederick William Mowbray, in the Great Seal
Patent Office, on the 30th September 1853.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I,
FREDERICK WILLIAM MOWBRAY, of Bradford, in the County of York,
Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Second day of April, in 'the
year of
our Lord One thousand eight hundred and fifty-three, in the sixteenth
year of Her reign, did, for Herself, Her heirs and successors, give and
grant unto me, the said Frederick William Mowbray, Her special
licence that I, the said Frederick William Mowbray, my executors,
administrators, and assigns, or such others as I, the said Frederick
William Mowbray, my executors, administrators, 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 Inven-
tion for "IMPROVEMENTS IN DOUBLING WOOL AND OTHER FIBROUS SUB-
STANCES," upon the condition (amongst others) that I, the said Frederick
William Mowbray, by an instrument in writing under my hand and
scal, should particularly describe and ascertain the nature of the said
Invention, and in what manner the same was to be performed, and
cause 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.
NOW KNOW YE, that I, the said Frederick William Mowbray, do
hereby declare the nature of the said Invention, and in what manner
the same is to be performed, to be particularly described and ascer-
tained in and by the following statement thereof (that is to say):
Heretofore, in doubling yarns of wool and other fibrous materials, it

page_text: has been the practice to support the bobbins from which the yarns are
being drawn upon fixed or stationary spindles, and the only motion
which such bobbins received was a motion each had upon its own, axis
by the act of drawing the yarn therefrom; consequently the only twist
obtained was that produced by the revolution of the flyer in the passage
of the yarns from the drawing, rollers to the flyer; and my improvement
consists in supporting each set of bobbins from which yarns are being
drawn to form a thread in a frame, to which rotary motion is given, in
order to put twist on the yarn in its passage to the drawing rollers, as
well as by the flyer in its passage from the "föllers:
*ontis
But that the Invention may be fully understood, I will proceed to
describe the means pursued by me. I would, however, state that I
have not thought it necessary to show, by drawings, a complete frame
and the different spéed wheels, as such are well understood by persons
acquainted with this class of machinery, but have confined myself to
showing so much only as will enable me to explain a mode of carrying
out my Invention.
DESCRIPTION OF THE DRAWING,
which represents the section of a frame, with my improvements applied.
a, are spindles formed at a', to receive the bobbins b, b; but the same
may be formed to receive other number of bobbins according to the
number of yarns required to be twisted together to form a thread. The
yarn from each bobbin b, passes through eyes c, c, (formed in the
frames c, affixed to the spindles a,) to the drawing rollers d, d, which
are formed and caused to revolve in the ordinary manner, except at a
greater speed, and thence the yarns pass to the flyer and bobbin e, as is
now the practice. Upon each spindle a, is formed a wharve f, around
which, as well as the wharve g, on each spindle e', passes a cord or
band h, from the drum or cylinder i, by which the spindles are each set
in motion.
Having thus described the nature of my said Invention, I would have
it understood that I do not confine myself to the precise details herein
shown and described, so long as the peculiar character of my Invention

page_text: be retained. But what I claim is, the putting twist on to yarns in
their passage to the rollers d, as well as in their passage therefrom to
the flyers.
In witness whereof, I, the said Frederick William Mowbray,
have hereunto set my hand and seal, this Twenty-ninth day of
September, in the year of our Lord One thousand eight hundred
and fifty-three.
FREDERICK WILLIAM MOWBRAY. (L.8.)
Witness, WILLIAM J. SALLITT.
