IMPROVEMENTS IN SADDLES FOR FRAMES USED IN THE SPINNING OF FLAX OR OTHER FIBROUS SUBSTANCES
Year: 1868

page_text: LETTERS PATENT to John Roberts Batty, of Leeds, in the County of
York, Machinist, for the Invention of "IMPROVEMENTS IN SADDLES
FOR FRAMES USED IN THE SPINNING OF FLAX OR OTHER FIBROUS
SUBSTANCES."
Sealed the 17th November 1868, and dated the 21st May 1868.
PROVISIONAL SPECIFICATION left by the said John Roberts Batty
at the Office of the Commissioners of Patents, with his Petition,
on the 21st May 1868.
I, JOHN ROBERTS BATTY, of Leeds, in the County of York, Machinist,
do hereby declare the nature of the said Invention for "IMPROVEMENTS
IN SADDLES FOR FRAMES USED IN THE SPINNING OF FLAX OR OTHER FIBROUS
SUBSTANCES," to be as follows:-
In spinning frames now in use the common adjusting saddle is worked
by the guide of a stand fixed on the beam of the spinning frame.
My improvements consist in what I call a link saddle constructed
with three links which is attached to the beam and is applicable with
or without stands. The first link is fixed at one end to the beam and
at the other to the second link, to which it is joined by an ordinary

page_text: loose joint, and the second and third links are attached to each other in
like manner as the first and second links. The advantage of this
arrangement is that the same saddle will give the same "nip" to a
smaller as it does to a larger roller.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said John Roberts Batty in the Great Seal Patent
Office on the 21st November 1868.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
ROBERTS BATTY, of Leeds, in the County of York, Machinist, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-first day of May, in the year of
our Lord One thousand eight hundred and sixty-eight, in the thirty-first
year of Her reign, did, for Herself, Her heirs and successors, give and
grant unto me, the said John Roberts Batty, Her special licence that I,
the said John Roberts Batty, my executors, administrators, and assigns,
or such others as I, the said John Roberts Batty, my executors, adminis-
trators, and assigns, should at any time agree with, and no others, from
time to time and at all times thereafter during the term therein ex-
pressed, 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 "IMPROVEMENTS IN SADDLES
FOR FRAMES USED IN THE SPINNING OF FLAX OR OTHER FIBROUS SUBSTANCES,'
upon the condition (amongst others) that I, the said John Roberts
Batty, my executors or administrators, by an instrument in writing
under my, or their, or one of their hands and seals, should par-
ticularly 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 John Roberts Batty, 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

page_text: by the following statement, reference being had to the Drawing hereunto
annexed, and to the letters and figures marked thercon (that is to
say):
:―
In spinning frames now in use the common adjusting saddle is worked
by the guide of a stand fixed on the beam of the spinning frame.
My improvements consist in the employment of what I call a link
saddle which is constructed of three parts connected together by flexible
joints and is attached to the horizontal beam of the machine and may be
adapted to the spinning frame either with or without stands.
In the accompanying Drawings I have shewn a small portion of a
spinning frame. Fig. 1 is a transverse vertical section, and Fig. 2 a front
view of the drawing part of a spinning frame with my improvements
adapted thereto. A, B, C, are the three parts of the self-acting link
saddle complete.
The first part A is a kind of bracket which is secured to the fixed
horizontal beam D of the spinning frame; B is a link for connecting
the first part A. or fixed bracket to the saddle C by an ordinary loose
or flexible joint; E is a slide for altering the reach; and F a lever
bracket for carrying the spring or weighted lever G, and to the upper
end of this lever G is jointed the rod N whereby the pressing rollers K
and L (or either, as the case may be) are weighted; H is the water
trough; I, the top drawing roller; J, the bottom drawing roller; K is
the top pressing roller; and L is a bottom large sized pressing roller;
M is a bottom small sized pressing roller, shewn by dots in Fig. 1,
and may be used instead of the larger roller L. The pressing rollers
are made of wood, gutter percha, or other suitable material. The rod N
carries at its outer end a knife edge which bears against the saddle
piece C and thus transmits pressure from the weighted lever G to the
saddle C, thus giving an uniform pressure whatever sized roller may
be used. O is the guide for the roving, and P is the adjusting screw
for raising or lowering the slide E for the purpose of altering and
adjusting the reach; Q represents the end of the frame on which the
bar D is mounted; R is a guide to keep the bottom pressing roller L
or M even with the bottom roller J. The advantage of this arrangement
is that with the same saddle the same "nip" may be given with a
smaller as with a larger roller.
Figures 3 and 4 represent a modification which is in fact merely a
mechanical equivalent for the link B, Fig. 1, in place of which arms

page_text: or pins a, a, are fixed transversely in the top end of the saddle C and
work in the forked socket B', as shewn in the Drawing. In this
instance a small bottom pressing roller M is shewn in place of the
larger one L, shewn in Fig. 1, but if desired a large roller, as shewn by
dots in Fig. 3, may be used in this arrangement.
Having now described my Invention of "Improvements in Saddles
for Frames used in the Spinning of Flax or other Fibrous Substances,'
and having explained the manner of carrying the same into effect, I
claim as the Invention secured to me by Letters Patent as aforesaid,
constructing the saddles of spinning frames of three parts jointed or
connected together as herein set forth for the purpose of rendering
the "nip" of the pressing rollers uniform without reference to the size
of the pressing rollers.
In witness whereof, I, the said John Roberts Batty, have here-
unto set my hand and scal, the Nineteenth day of November,
in the year of our Lord One thousand eight hundred and sixty-
eight.
Signed and sealed by the said
John Roberts Batty in my
presence,
JA. W. HAMILTON RICHARDSON,
JOHN R. BATTY. (L.S.)
Solicitor,
Leeds.
