page_text: We WILLIAM BLACKBURN Worsted Spinner, and SAMUEL BLACKBURN Foreman
Mechanic, both of Clarence Mills and Brook Mills Cleckheaton in the county of
York seek leave to amend the specification of Letters Patent, No. 3606 of 1885,
as shown in red ink in the copy of the original specification hereunto annexed :—
Our reasons for making this Amendment are as follows :—
To make the specification read more clearly and correctly.
DECISION.
I hereby grant leave to the above named William Blackburn and Samuel
Blackburn to amend the said Specification in the manner proposed.
J. CLARK HALL,
Deputy Comptroller.

page_text: Improvements in the Method of and Apparatus for Driving the
Spindles of Machinery for Spinning and Twisting Fibres.
We WILLIAM BLACKBURN Worsted Spinner and SAMUEL BLACKBURN Foreman
Mechanic both of Clarence Mills and Brook Mills Cleckheaton in the county of
York do hereby declare the nature of the said Invention for "IMPROVEMENTS IN
THE METHOD OF AND APPARATUS FOR DRIVING THE SPINDLES OF MACHINERY FOR
SPINNING AND TWISTING FIBRES," to be as follows:-
The object of our invention is to give a long traverse, and so use long bobbins
also to insure a regular twist in spinning and twisting fibres.
I employ pivotted brackets which carry the shafting upon which the tin
cylinders are mounted, the bands pass as usual from the cylinders to the wharles,
but as the spindles and lifter rail rise or fall, on one side the frame, the cylinder
follows and so any length of traverse, can be given to the spindles, connecting rods
are preferably used, from the pivotted brackets, to the lifting rail, to insure no
strain upon the bands by the driving belt, this apparatus ensures equal tension" on
the bands, from the top to the bottom of the traverse of the spindles.

page_text: We WILLIAM BLACKBURN Worsted Spinner and SAMUEL BLACKBURN Foreman
Mechanic both of Clarence Mills and Brook Mills Cleckheaton in the county of
York, do hereby declare the nature of the said Invention for "IMPROVEMENTS
IN THE METHOD OF AND APPARATUS FOR DRIVING THE SPINDLES TUBES OF
MACHINERY FOR SPINNING AND TWISTING FIBRES," 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 our invention is to give a long traverse, and so use long bobbins,
also to insure a regular twist in spinning and twisting fibres.
Instead of the cylinder. being mounted on a fixed shaft, I employ pivotted
brackets, which carry the shafting upon which the tin cylinders are mounted, the
bands pass as usual from the cylinders to the wharles but as the spindles tubes
and lifter rail rise or fall on one side of the frame, the cylinder follows, and so any
length of traverse can be given to the spindles tubes: or connecting or radius rods
may be used from the pivotted brackets, to the lifting rail, to insure there being
no strain put upon the bands by the driving belt, this apparatus insures equal
tension on the bands from the top to the bottom of the traverse of the spindles
tubes, and will do with or without the radius or connecting rod.
DESCRIPTION OF DRAWINGS.
Fig. 1 shews an end elevation in section of spinning frame, with my improve-
ments attached, but without the radius rod.
Fig. 2 shows an end elevation in section of spinning frame, with my improve-
ments attached, and radius rod.
Fig. 3 is a plan of Fig. 2, partly in section.
A is the frame, B the bracket or bearing pivotted at C, (on cross piece M) and
carrying the cylinder D, E are the bauds, driving the wharles F, ofn the spindles G,
H is the lifter rail, J the cap; as the spindles tubes and lifter rail rise or fall, on
one or other side of the frame, the cylinder moves on its pivot following the pull
of the bands towards one or other side of the frame, according to the position or
traverse of the spindles tubes, thus the bands are kept at one equal tension, from
the top to the bottom of the traverse of the spindles tubes, without strain, so
insuring even and regular twist, at the same time there is little or no wear and
tear of the bands, and less friction upon the spindles, the frames can be driven
with one fourth of the power, if required radius or connecting rod K, may be used
from the pivotted brackets B, to lifter rail H (see Figs 2 and 3) to prevent any
possibility of strain being put upon the bands by the driving belt.

page_text: Having now particularly described and ascertained the nature of our said
Invention and in what manner the same is to be performed we declare that what
we claim is :-
1 In spinning and twisting fibres mounting the cylinder on pivotted bearings
(with or without connecting rod) so that it may move on its pivot, and allow any
length of traverse to be made with equal tension upon the bands, giving a regular
twist to the yarn.
