Year: 1866

page_text: LETTERS PATENT to George Lowry, of Salford, in the County of Lan-
caster, Engineer, for the Invention of "IMPROVEMENTS IN MACHINERY FOR
SPINNING FLAX AND OTHER LIKE FIBROUS MATERIALS."
Sealed the 1st March 1867, and dated the 4th September 1866.
PROVISIONAL SPECIFICATION left by the said George Lowry at the
Office of the Commissioners of Patents, with his Petition, on the
4th September 1866.
I, GEORGE LOWRY, of Salford, in the County of Lancaster, Engineer, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN
MACHINERY FOR SPINNING FLAX AND OTHER LIKE FIBROUS MATERIALS," to be as
follows:-
The object of this Invention is to simplify and improve certain parts of a
spinning frame for flax and other like fibrous materials where the rove is drawn
out or elongated, and consists in adapting adjustable bearings for the ends of the
axle of the top pressing roller to work in; also I construct the saddle to hang
by an adjustable bearing upon the axle of the said top pressing roller, or upon
a suitable rod or bearing provided for the same; the length of the saddle is
capable of adjustment by means of a screw and nut attached thereto in order
to suit the length of reach required for spinning different classes of material.
Also I construct the bolsters or bushes in which the spindles run in spinning
and roving frames with a loose wa-her, which has its upper edge rounded in

page_text: contact with the collar on the bolster, suitably shaped to receive it, so that on
screwing tho bolster to the rail tho round edge of the washer allows the
bolster to be adjusted to any little inequality in the bore or other like
derangement.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said George Lowry in the Great Seal Patent Office on the
4th March 1867.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GEORGE
LOWRY, of Salford, in the County of Lancaster, Engineer, send greeting..
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fourth day of September, in the year of our
Lord One thousand eight hundred and sixty-six, in the thirtieth year of Her
reign, did, for Horself, Her heirs and successors, give and grant unto me, the
said George Lowry, Her special licence that I, the said George Lowry,
my executors, administrators, and assigns, or such others as I, the said
George Lowry, 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 "IMPROVEMENTS IN
MACHINERY FOR SPINNING FLAX AND OTHER LIKE FIBROUS MATERIALS," upon the
condition (amongst others) that I, the said George Lowry, 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 George Lowry, 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 following
statement :-
The object of this Invention is to simplify and improve certain parts of a
spinning frame for flax and other like fibrous materials where the rove is
drawn out or elongated, and consists in adapting adjustable bearings for the
ends of the axle of the top pressing roller to work in; also I construct the

page_text: saddle to hang by an adjustable bearing upon the axle of the top pressing
roller or upon a suitable rod or bearing provided for the same; the length
of the saddle is capable of adjustment, by means of a screw and nut attached
thereto, in order to suit the length of reach required for spinning different
5 classes of material. Also I construct the bolster or bushes on which the
spindles run in spinning or roving frames with a loose washer, which has its
upper edge rounded in contact with the collar on the bolster suitably shaped
to receive it, so that on screwing the bolster to the rail the round edge of
the washer permits the bolster to be adjusted to any little inequality in the
bore or other like derangement.
And in order that my Invention may be readily understood and carried
into effect I will proceed to describe the accompanying Sheets of Drawings,
reference being made to the figures and letters marked thereon.
DESCRIPTION OF DRAWINGS.
Figure 1 is an end elevation, partly in section, and Figure 2 is a plan
showing part of a machine for spinning flax and other like fibrous materials
to which my improvements aro applied; Fig. 8, a sectional elevation with the
saddle removed in order to shew adjustable bearing. Such portions of the
machine as are not shown in the Drawings are constructed in the ordinary
manner.
a is the top pressing roller; 6 is the adjustable bearing, seen best in Figure 2;
e is the saddle made without cross arm, and provided with notches, and weighted
in the ordinary manner, but constructed as will be hereafter described; fis
the bearing, open at the bottom, by means of which the saddle e is suspended
on the axis of the top pressing roller a; one end of the bearing fis tapped
and inserted into a slot in the saddle c, so as to be actuated by the screw g
which moves in suitable bearings in saddle e. The tightening screw h which
can move in a slot in front of the saddle e is for the purpose of fixing the
bearing when the saddle e has been adjusted to the proper position for
spinning.
The modo of operation is as follows:-When a shorter reach is desired
the usual screw i is turned round so as to cause the top roller j to approach
the bottom roller k to the required distance, as in machines of the ordinary
construction; the top pressing roller a in the meantime remaining in the
bearings b. The set screw d having been slackened the bearing bis adjusted,
and the set screw d is screwed up; the tightening screw his then slackened,
and the screw g is moved round so as to cause the bottom pressing roller
to approach the top pressing roller a, so as to acquire the requisite position

page_text: for spinning, after which the tightening screw h is screwed up and the machine
is ready for work.
Figure 4 is a sectional elevation of the bolster used in spinning and roving
frames. is the washer, which is shaped to fit the under side of the collar y
on the bolster, and serves to adjust the bolster should the hole in which it
enters be not true.
What I claim as of my Invention is,―
Firstly, placing the axes of the top pressing rollers in machines for spinning
flax and other like fibrous materials in adjustable bearings, so as to accommodate
any length of reach required for spinning different classes of materials.
Secondly, the method shown and described in reference to Figures 1 and 2
for effecting the required adjustment of the said bearings, and also the adjust-
ment of the bottom pressing rollers.
Thirdly, constructing the saddles of machines for spinning flax and other
like fibrous materials without cross arms, so that any size of bottom pressing
rollers can be used.
Lastly, the mode of adjusting the bolsters using in roving and spinning
frames by means of a convex washer beneath the collar on the same, as
herein-before described.
In witness whereof I, the said George Lowry, have hereunto set my
hand and seal, this First day of March, in the year of our Lord One
thousand eight hundred and sixty-seven.
