IMPROVEMENTS IN MACHINERY PAR SPINNING PLAY AND OTHER FIRRES"
Year: 1869

page_text: LETTERS PATENT to Joseph Newton, of Leeds, in the County of
York, Machine Maker, for the Invention of "IMPROVEMENTS IN
MACHINERY PAR SPINNING PLAY AND OTHER FIRRES"
PROVISIONAL SPECIFICATION left by the said Joseph Newton at the
Office of the Commissioners of Patents, with his Petition, on the
18th February 1869.
I, JOSEPH NEWTON, of Leeds, in the County of York, Machine Maker,
do hereby declare the nature of the said Invention for "IMPROVEMENTS IN
MACHINERY FOR SPINNING FLAX AND OTHER FIBRES," to be as follows:-
In the Specification of a former Patent granted to David Cochrane
on the 11th day of June 1866 (No. 1588) was described the con-
structing spinning frames with the saddles which support the axes of
the two pairs of pressing rollers each supported by a single bracket or
arm.
According to my Invention, in place of making the supports which
carry the saddles with projecting pins to enter into slots in the saddles
as described in the above-mentioned Specification, I form the support

page_text: with two parallel checks between which the centre portion of the
saddle is received; a pin carried by these cheeks and passing across the
space between them enters a slot in the saddle, and the saddle is thus
supported. The saddle is formed with parallel sides which fit between
the two parallel cheeks of the support, consequently the cheeks may
be formed to fit against the sides of the saddle for any desired portion
of its length, whilst the central portion of the saddle in which the slot
is made and which fits between the cheeks may also be made of
sufficient depth to give steadiness. By thus constructing the saddles
and their brackets or supports a large bearing surface is obtained to
prevent any lateral motion of the saddle, and in addition, as the sides
neither of the saddles nor the brackets have any projections from them,
they may be fitted by grinding or filing at a very small cost. The
bearing for the axis of the pair of the lower pressing rollers is fitted into
a notch or recess at the lower end of the saddle in the manner usual
and well known. The bearing for the axis of the upper rollers is
capable of being moved to and from the fixed bearing by sliding it
along a slot formed longitudinally in the saddle, and it is fixed by a
screw, as described in the Specification above mentioned, but in addition
I also form notches along the edges of this slot, and employ a collar
around the screw having a projection on its under side, which by means
of the screw may be pressed into one or other of these notches, and
thus the moveable bearings on all the saddles of a spinning frame may
readily be fixed at one even distance from the fixed bearings carried by
such saddles. Each of the saddles is also arranged to be acted upon by
a spring or weight so as to draw the pressing rollers against the drawing
and retaining rollers as is usual.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Joseph Newton in the Great Seal Patent Office
on the 18th August 1869.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOSEPH
NEWTON, of Leeds, in the County of York, Machine Maker, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Eighteenth day of February, in the year

page_text: of our Lord One thousand eight hundred and sixty-nine, in the thirty-
second year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said Joseph Newton, Her special licence that
I, the said Joseph Newton, my executors, administrators, and assigns,
or such others as I, the said Joseph Newton, 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
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 "IMPROVEMENTS IN MACHINERY
FOR SPINNING FLAX AND OTHER FIBRES," upon the condition (amongst others)
that I, the said Joseph Newton, my executors or administrators, by an
instrument in writing under my, or their, or one of their hands and
seals, 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 Joseph Newton, do hereby declare
the nature of the said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the
following statement thereof, that is to say:-
In the Specification of a former Patent granted to David Cochrane
on the 11th day of June 1866 (No. 1588) was described the construct-
ing spinning frames with the saddles which support the axes of
the two pairs of pressing rollers cach supported by a single bracket
or arm.
According to my Invention, in place of making the supports which
carry the saddles with projecting pins to enter into slots in the saddles
as described in the above-mentioned Specification, I form the support
with two parallel cheeks between which the centre portion of the saddle
is received; a pin carried by these cheeks and passing across the space
between them enters a slot in the saddle, and the saddle is thus sup-
ported. The saddle is formed with parallel sides which fit between the
two parallel checks of the support, consequently the checks may be
formed to fit against the sides of the saddle for any desired portion of
its length, whilst the central portion of the saddle in which the slot is
made and which fits between the checks may also be made of sufficient

page_text: depth to give steadiness. By thus constructing the saddles and their
brackets or supports a large bearing surface is obtained to prevent any
lateral motion of the saddle, and in addition, as the sides neither of the
saddle nor the brackets have any projections from them, they may be
fitted by grinding or filing at a very small cost. The bearing for the
axis of the pair of lower pressing rollers is fitted into a notch or recess
at the lower end of the saddle in the manner usual and well known.
The bearing of the axes of the upper rollers is capable of being moved
to and from the fixed bearing by sliding it along slot formed longitu-
dinally in the saddle, and it is fixed by a screw, as described in the
Specification above mentioned, but in addition I prefer also to form
notches along the edges of this slot and employ a collar around the screw
having a projection on its under side, which by means of the screw may
be pressed into one or other of these notches, and thus the moveable
bearings on all the saddles of a spinning frame may readily be fixed
at one even distance from the fixed bearings carried by such saddles.
Each of the saddles is also arranged to be acted upon by a spring or
weight so as to draw the pressing rollers against the drawing and
retaining rollers as is usual.
Having thus stated the nature of my Invention I will proceed to
describe more fully the manner of performing the same.
At Figure 1 of the Drawings hereunto annexed is shown a front view
of so much of a spinning frame as is necessary for shewing the manner
in which I prefer to carry out my Invention; Figure 2 is a transverse
section taken through the same parts of the spinning frame; Figures 3
and 4 shew one of the saddles separately; and Figures 5 and 6 shew one
of the brackets or supports by which the saddles are carried.
The form of the bracket and saddle is clearly shewn by these
views; the bracket I prefer to form of cast iron, and the opposite surfaces
of the two cheeks a, a, are cast to receive the saddle between them,
holes are also bored through the cheeks to receive the pin 6 which is to
support the saddle. I cast the saddle in either brass or iron, and the
fixed bearing c I fit to it in the ordinary manner. The two parallel
sides of the saddle are finished up either by grinding or otherwise until
the saddle is of a width to fit between the checks of the bracket; the
notches c¹, c', are also cut in its edge, as shewn, and the slot c² is brought
to the proper width to receive the pin b. The portion of the saddle in
which the slot is formed is in order to give steadiness made deeper than

page_text: the other parts of the saddle, as is clearly shewn by the Drawings. The
moveable bearing is fitted to the saddle in such a manner that it can
be slid towards or from the fixed bearing as is usual and be- fixed to
the saddle at any desired point by a binding screw c', around which is
placed a collar c³ having a tooth or projection, as above described, to enter
one or other of the notches c'. I form such notches in the process of
casting the saddles. In Figures 1 and 2 of the Drawings d is the hori-
zontal beam, which runs from end to end of the spinning frame as is usual;
to this are attached the brackets which are to support the saddles, and
also other brackets e, e, to support the upper and lower back rollers g,g,
as is usual. The bearings carrying the upper back rollers are capable
of being slid along the brackets e, e, and held in any position by
screws, as shewn, and lines are formed along the edge of each saddle,.
so that all the upper bearings can readily be set at one even distance
from the lower fixed bearings. k, k, are the lower pairs of front or
pressing rollers, the axles of which are received in the fixed bearing
of the saddle, and 1, 1, are the upper pairs of front or pressing rollers,
the axles of which are received in the moveable bearings c³, c; p is a
weighted lever for drawing the saddle and the rollers carried by it
towards the back rollers in the ordinary manner.
Having thus described the nature of my Invention, and the manner
of performing the same, I would have it understood that what I claim
is, the constructing the saddles of spinning frames and the supports
or brackets which carry them, substantially as herein described.
I also claim, forming the central portion of a saddle which is received
between checks on its support or bracket deeper than the other portions
of the saddle in order to obtain steadiness.
In witness whereof, I, the said Joseph Newton, have hereunto
set my hand and seal, this Seventh day of August, in
the year of our Lord One thousand eight hundred and sixty-
nine.
