Year: 1862

page_text: LETTERS PATENT to John Muir Hetherington, of Manchester, in the
County of Lancaster, Machine Maker, and Thomas Jackson, of Stock-
port, in the said County, Manager, for the Invention of "IMPROVEMENTS
IN MACHINERY OR APPARATUS FOR PREPARING, SPINNING, AND
COTTON AND OTHER FIBROUS MATERIALS."
DOUBLING
Sealed the 30th December 1862, and dated the 2nd July 1862.
PROVISIONAL SPECIFICATION left by the said John Muir Hetherington
and Thomas Jackson at the Office of the Commissioners of Patents, :
with their Petition, on the 2nd July 1862.
We, JOHN MUIR HETHERINGTON, of Manchester, in the County of Lan-
caster, Machine Maker, and THOMAS JACKSON, of Stockport, in the said
County, Manager, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN MACHINERY OR APPARATUS FOR PREPARING, SPINNING, AND
DOUBLING COTTON AND OTHER FIBROUS MATERIALS," to be as follows
ן
Our Invention relates, firstly, to a method of lubricating spindles used.in
preparing, spinning, and doubling. For this purpose we construct a chamber,
around the footstep forming a reservoir for the lubricating material, and
through the lower end of the said footstep we bore a hole or holes so that the
oil or other such substance may flow to the spindle..

page_text: Another part of our Invention relates to a method of obtaining the drag in
those ordinary throstle bobbins which are mounted upon the spindles and not
upon tubes, and consists in adapting to the bottoms thereof plates of metal
caused to revolve with the bobbins by means of a pin or other connexion.
The central part of the said plate we use as a bearing for the spindle, and
with this view we furnish it with a projecting part passing into the bobbin ;
between the plate and the rail we adapt a leather or other such washer.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said John Muir Hetherington and Thomas Jackson in the
Great Seal Patent Office on the 2nd January 1863.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JOHN
MUIR HETHERINGTON, of Manchester, in the County of Lancaster, Machine
Maker, and THOMAS JACKSON, of Stockport, in the said County, Manager,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Second day of July, in the year of our Lord One
thousand eight hundred and sixty-two, in the twenty-sixth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto us, the said
John Muir Hetherington and and Thomas Jackson, Her special license that we,
the said John Muir Hetherington and Thomas Jackson, our executors, adminis-
trators; and assigns, or such others as we, the said John Muir Hetherington.
and Thomas Jackson, our executors, administrators, and assigns, should at
any time agree with, and no others, from time to time and at all times there-
after 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 OR APPARATUS FOR PREPARING, SPINNING, AND DOUBLING COTTON AND
OTHER FIBROUS MATERIALS," upon the condition, amongst others, that we, the
said John Muir Hetherington and Thomas Jackson, by an instrument in
writing under our hands and seals (or under the hand and seal of one of us)
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.

page_text: NOW KNOW YE, that we, the said John Muir Hetherington and
Thomas Jackson, do hereby declare the nature of our said Invention, and in
what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement and accompanying Drawing
(that is to say) -
:-
Our Invention relates, firstly, to the lubrication of spindles of preparing,
spinning, and doubling machines. The spindle turns at its lower end in a foot-
step which has a chamber formed around it, provided at its lower end with a
hole or holes through which lubricating material may pass from the said
chamber to the spindle.
Another part of our Invention consists in a method of obtaining the "drag"
for the ordinary throstle bobbins which are carried by the spindles and not by
tubes. To effect this drag, we employ a plate of metal which revolves with
the bobbin by means of a pin or other such connexion. This plate is bevilled
from its outward part towards the centre, and is furnished with a projection
extending into the bobbin.
In the accompanying Drawing these two improvements are shewn in
combination, but they are not necessarily connected, and may be used sepa-
rately, if desired. The spindle is at a, turning at its lower end in a foot-
step 6; formed with this footstep, and extending around it, is a chamber c,
fitted with a cover d, and provided with an aperture or apertures, as at e.
Lubricating material being placed in the chamber c, flows through the aper-
ture e to the spindle, and thus a constant supply is kept up, any superfluous
quantity which passes upward falling again into the reservoir.
Our second improvement is as follows:-The bobbin is at f resting upon a
metal disc g, and the two are caused to revolve together by means of a pin h.
The disc g is bevilled off from its outward circumference towards the centre,
and by increasing or diminishing this bevil, any desired amount of drag may
be attained by causing the flattened part to run in contact with a leather or
other washer, as at i, and thus any great change required in the drag may be
effected by altering the bevil of the disc or any minor change by altering the
size of the washer. The central part of the disc g is provided with a boss k,
which extends into the bobbin, and supports the spindle.
Having thus described and ascertained the nature of our said Invention,
and the manner in which the same is to be performed, we desire it to be
understood that we claim, as secured to us under the above in part recited
Letters Patent,-
Firstly, the use of the lubricating chamber formed around the footstep of
the chindla

page_text: Secondly, the bevilled construction of the metal disc for obtaining and regu-
lating the "drag."
In witness whereof, I, the said John Muir Hetherington, have hereunto
set my hand and seal, the Thirtieth day of December, in the year of
our Lord One thousand eight hundred and sixty-two.
JOHN MUIR HETHERINGTON. (L.S.)
