FREE AND SELF-ACTING SADDLE FOR WET FLAX-SPINNING FRAMES
Year: 1864

page_text: LETTERS PATENT to William Leuty, of Lille, for the Invention of "
FREE AND SELF-ACTING SADDLE FOR WET FLAX-SPINNING FRAMES."
Sealed the 26th July 1864, and dated the 23rd March 1864.
PROVISIONAL SPECIFICATION left by the said William Leuty at the
Office of the Commissioners of Patents, with his Petition, on the
23rd March 1864.
I, WILLIAM LEUTY, of Lille, do hereby declare the nature of the said Inven-
tion for "A FREE AND SELF-ACTING SADDLE FOR WET FLAX-SPINNING FRAMES," to
be as follows:
This .Invention of improvements in spinning machinery relates more
particularly to that class of machinery which is employed for spinning flax
by the wet 'method, and consists in a novel construction of. parts for giving
the requisite pressure to the nipping and drawing rollers. In the improved
machine the presser or saddle piece, whereby pressure is imparted to the:
drawing rollers, is suspended from a fixed horizontal spindle, on which are.
mounted loosely brass rollers, which bear against fluted brass rollers behind.
The axles of the drawing rollers below turn in bearings in the-saddle, which

page_text: turns on the spindle above as its axis of motion, so that whatever may be the
diameter of the drawing rollers the nip of the latter on the rollers behind will
always be at the same point. The pressure of the saddle piece is given by
means of a weighted bell-crank lever behind, and is regulated by a rod
provided with a screw and thumb nut at one end, and connected by its other
end to the bell-crank lever.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William Leuty in the Great Seal Patent Office on the
23rd September 1864.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
LEUTY, of Lille, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-third day of March, in the year of our
Lord One thousand eight hundred and sixty-four, in the twenty-seventh year
of Her reign, did, for Herself, Her heirs and successors, give and grant
unto me, the said William Leuty, Her special license that I, the said
William Leuty, my executors, administrators, and assigns, or such others.
as I, the said William Leuty, 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 Invention
for "A FREE AND SELF-ACTING SADDLE FOR WET FLAX-SPINNING FRAMES," upon
the condition (amongst others) that I, the said William Leuty, by an instru-
ment in writing under my hand and seal, should particularly describe and
ascertain the nature of the said Invention, and in what manner the. samé.
I was to be performed, and cause the same to be filed in the Great Seali
Patent Office within six calendar months next and immediately after the date
of the said Letters Patent.
NOW KNOW YE, that I, the said William Leuty, do hereby declare
the nature of my said Invention, and in what manner the same is to be:
performed, to be particularly described and ascertained in and by the fol-i
lowing statement, reference being had to the Drawings hereunto annexed,
and to the letters and figures marked thereon (that is to say)
The improvements which I have made in flax-spinning machines by the

page_text: wet method will be clearly understood by referring to the accompanying
Drawings.
Fig. 1 represents a new or improved system of drawing complete with
brass and boxwood pressing rollers, self-acting saddle or presser, and fluted or
grooved rollers marked 5 and 6; Fig. 2 represents the improved system of
drawing; 8 is the fixed spindle, which forms one of the principal features of
the Invention; A, A, are brass rollers; 4 are fluted boxwood drawing rollers;
5, fluted feeding rollers, also of brass; 6, fluted brass drawing rollers;
7, screwed rod connected at one end to a weighted bell-crank lever, which
gives the pressure, and is provided at the other end with a fly or thumb nut 8
for regulating the pressure of the weighted lever; 9 is a brass horizontal bar
for bearing against the presser or saddle, on the back of which it is capable of
being moved up or down, so that it may be adjusted according to the diameter
of the drawing or pressing rollers. The dotted lines indicate the different
positions of the presser or saddle according to the different diameters of the
boxwood roller 4. Fig. 8 represents the fixed spindle (the new feature)
upon which the rollers A, A, turn, the bearings of which loosely embrace the
spindle or rod of the saddle piece; this spindle 3 rises and falls according to
the requirements of the work, each of its ends enters into the grooves of the
supports B, B, Fig. 1, which are connected to the bearings of the column of the
feeding rollers, and consequently follow its motions; this spindle forms one
of the principal features of the Invention, as it admits of the axes of the
drawing rollers 5 and the hollow rollers A, A, being made nearly coincident,
in consequence of this spindle being stationary, therefore, whether the
diameter of the boxwood rollers 4 be large or small, they will always fall on
the right point of contact on the roller 6, as indicated by the dotted lines in
Fig 2. The employment of this immoveable spindle enables me to dispense
with the supports which would guide the arms of the saddle or presser
according to the old plan, and would hamper the free movements of the
saddle or presser, and would occasion friction and wear at the expense of the
moving power, and also of good work and cleanliness; by thus dispensing with
the use of the arms, rollers of much larger diameter than heretofore may be
employed. This is an important economy, because formerly it was necessary
to diminish the size of the rollers to allow the arms of the presser to pass
freely between the presser and the drawing ruller 6.
Having now described my Invention of a free and self-acting saddle
for wet flax-spinning frames, and having explained the manner of carrying
the same into effect, I claim as the Invention secured to me by Letters

page_text: Patent as aforesaid, the arrangement and construction of parts herein set
forth, or any mere modification thereof, for producing a self-regulating
pressure on the rollers of wet spinning frames.
In witness whereof, I, the said William Leuty, have hereunto set my
hand and seal, the Twenty-second day of September, in the year of
our Lord One thousand eight hundred and sixty-four.
W. LEUTY. (L.S.)
