in the County of Middlesex, Gentleman, for the Invention of "IMPROVE-
MENTS IN MACHINERY OR APPARATUS FOR SPINNING COTTON AND
FIBROUS MATERIALS."-A communication from abroad by James Eaton,.

Sealed the 26th May 1868, and dated the 31st December 1867.
PROVISIONAL SPECIFICATION left by the said John Henry Johnson at
the Office of the Commissioners of Patents; with his Petition, on the
31st December 1867...
I, JOHN HENRY JOHNSON, of 47, Lincoln's Inn Fields, in the County of
Middlesex, Gentleman, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN MACHINERY OR APPARATUS FOR SPINNING COTTON AND OTHER
FIBROUS MATERIALS," a communication to me from abroad by James Eaton,
of Boston, in the United States of America, to be as follows, that is to say:
This Invention relates, firstly, to improvements in cop spindles of spinning
machines, whereby greater facility is afforded for more readily slipping off
the yarn when piecing up; and, secondly, to improvements in the lubrication
of the shafts of the driving drums of spinning machines.
According to the first part of this Invention it is proposed to form the end or
tip of the cop spindles of a slightly reduced diameter, the reduction extending
a short distance down such spindle and forming a shoulder thereon: The

page_text: reduced part may be formed either concentric or eccentric with the axis of the
spindle, and is provided with a helical slot or groove in which the yarn enters
and passes into a small central aperture made vertically in the top of the
spindle.
The second part of this Invention consists in the application of oil or other
Jubricating liquid to the shafts of the driving drums of spinning machines, the
bearing in which such shafts work being provided with a recess for containing
sponge or other suitable absorbent material in such a way as to prevent waste
of the lubricating material and confine its action to the shaft against which it
hears.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said John Henry Johnson in the Great Seal Patent Office on
the 16th June 1868.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
HENRY JOHNSON, of 47, Lincoln's Inn Fields, in the County of Middlesex,
Gentleman, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Thirty-first day of December, in the year of our Lord
One thousand eight hundred and sixty-seven, in the thirty-first year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said John Henry Johnson, Her special license that I, the said John Henry
Johnson, I executors, administrators, and assigns, or such others as I, the
said John Henry Johnson, my executors, administrators, or 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, exereise, and vend, within the United Kingdom of Great Britain
and Ireland, the Channel Islands, and Isle of Man, an Invention for "Iж-
PROVEMENTS IN MACHINERY OR APPARATUS FOR SPINNING COTTON AND OTHER FIBROUS
MATERIALS," a communication from abroad by James Eaton, of Boston, in
the United States of America, upon the condition (amongst others) that
I, the said John Henry Johnson, my executors or administrators, by
an instrument in writing under my hand and seal, 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 imme-
diately after the date of the said Letters Patent.

page_text: NOW KNOW YE, that I, the said John Henry Johnson, 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, reference being had to the accompanying Drawings and to the
letters and figures marked thereon, that is to say :-
The said Invention relates, firstly, to improvements in the cop spindles of
spinning machines, whereby greater facility is afforded for more readily
slipping off the yarn from the tip of the spindle when "piecing up;" and,
secondly, to improvements in the lubrication of the shafts of the driving
drums of spinning machines.
In carrying out the first part of this Invention, which is illustrated by the
annexed Sheet of Drawings, it is proposed to form the end or tip of cop
spindles of a slightly reduced diameter, the reduction extending a short
distance down such spindle and forming a shoulder thereon. The reduced
part may be formed either concentric or eccentric with the axis of the spindle,
and is provided with a helical slot or groove in which the yarn enters and
passes into a small central aperture made vertically in the top of the spindle.
Figure 1 of the accompanying Sheet of Drawings represents the ordinary
form of cop spindle. Figure 2 is an enlarged view of a cop spindle, the
upper end or tip of which is constructed according to the first part of this
Invention; the thread (colored red) is here shown in the position it assumes
when being spun. Figure 3 is a similar view with the thread disengaged
from the tip of the spindle for the purpose of "piecing up." Figure 4 is a
plan of the tip of the spindle corresponding to Figure 3. Figures 5, 6, and
7 are similar views of a slightly modified form of spindle as herein-after
described.
'
a is the main portion of the spindle; b, the cop; c, the thread shown by the.
red line; and d is the tip of the spindle, which in lieu of tapering gradually
into the body of the spindle itself, as shown in Figure 1, is of a slightly
reduced diameter so as to leave a shoulder between this reduced portion and
the main part of the spindle. This reduced portion d of the spindle may
either be made concentric with the axis of the spindle, as shown in Figures 2,
3, and 4, or eccentric thereto as shown in the modified form of spindle at
Figures 5, 6, and 7. In all other respects both spindles are precisely alike.
A curved or helical slot or channel e is formed in each tip d, such slot
commencing at the cylindrical surface or periphery of the lower portion of the
tip d, and terminating in a central aperture f, which aperture should coincide.
with the axial line of the spindle whether the reduced tip d be made concentri-
cally with or eccentrically to the said axis as shown clearly by the respective

page_text: plan views of the two arrangements Figures 4 and 6. By having a
projecting shoulder round the tip d the thread is much more readily dis-
engaged from the curved slot when requisite.
I shall now proceed to describe the second part of the said Invention,
which has reference to a peculiar mode of applying oil or other lubricating
liquid to the shafts of the driving drums of spinning machines, and consists
essentially in providing a recess or recesses of any convenient size and form
in the brasses or bearings in which the journals of the shafts of the driving
drums of spinning machines work, such recesses being filled with sponge or
other suitable absorbent material, in such a way as to prevent waste of the
lubricant absorbed thereby, and confine its action to the journals of the shaft
against which such absorbent material bears..
Having now described and particularly ascertained the nature of the said
Invention, and the manner in which the same is or may be used or carried
into effect, I would observe in conclusion that what I consider to be novel
and original, and therefore claim as the Invention secured to me by the
herein-before in part recited Letters Patent is,-
First. The so forming the tips of the spindles of spinning machines that
the body of the spindle itself shall form a shoulder or enlargement at the
lower portion or base of the tip which is of reduced diameter, and the
application to such a tip of a curved or helical slot or channel terminating at
its upper end in the axial centre line of the spindle, substantially as and for
the purpose herein-before described and illustrated by the Drawings.
Second. The lubricating the journals of the driving drums of spinning
machines by the application of a piece of sponge or other suitable absorbent
material saturated with oil or other liquid lubricant and contained in a recess
or recesses made for that purpose in the brasses or bearings of the said
journals.
In witness whereof, I, the said John Henry Johnson, have to this my
Specification set my hand and seal, this Sixteenth day of June, One
thousand eight hundred and sixty-eight..

NRY JOHNSON. (L.E.)
