IMPROVEMENTS IN SPINDLE BOLSTERS OF SPINNING FRAMES
Year: 1872

page_text: LETTERS PATENT to Alexander Melville Clark, of 53, Chancery Lane,
in the County of Middlesex, Patent Agent, for the Invention of
"IMPROVEMENTS IN SPINDLE BOLSTERS OF SPINNING FRAMES."-A com-
munication from abroad by Charles Franklin Wilson and Jesse
Edward Folk,, both of the City of Brooklyn, County of Kings, and
State of New York. United States of America.
PROVISIONAL SPECIFICATION left by the said Alexander Melville
Clark at the Office of the Commissioners of Patents, with his
Petition, on the 2nd December 1872.
I, ALEXANDER MELVILLE CLARK, of 53, Chancery Lane, in the
County of Middlesex, Patent Agent, do hereby declare the nature of
the said Invention for "IMPROVEMENTS IN SPINDLE BOLSTERS OF SPINNING
FRAMES," to be as follows:-
The spinning bolsters of spinning frames in consequence of the rapid
revolving motion of the spindle is very liable to wear and to be drawn

page_text: by the thread out of place, and many attempts have been made and
much ingenuity expended to insure such a lubrication of the spindle as
will prevent it from wearing, but such attempts have hitherto been but
partially successful.
This Invention is designed to accomplish the desired object, and
consists in a revolving cup and journal box within a shell, and in the
mode of confining the same in the rail of the spinning frame, the con-
struction and arrangement of parts being as herein-after described.
The cup which is attached to the spindle revolves in an annular space
between the box and the shell which surrounds it, the upper portion of
the shell being an oil reservoir provided with an orifice for introducing
oil the top of which is formed to tightly enclose the spindle without
causing friction. The orifice for the oil is made with a punch which
leaves a lip which is turned in so as to form a guard to the spindle when
the oil is introduced. The oil introduced into the reservoir or chamber
runs down the spindle to the bottom of the box, from whence it works
into the cup, the centrifugal force then carrying it up to one or more
apertures in the journal box provided with projecting lips which break
the upward current and force the oil through the apertures and in
contact with the bearing or spindle. A constant circulation of the oil is
thus kept up so that the spindle constantly runs in oil. Orifices in the
shell opposite the apertures in the box are also provided. A nut beneath
the rail screws on to the shell and securely fastens the bearing to the
rail.
These bolsters are usually secured to the rail by means of set screws
bearing against the side. This mode is objectionable when an outer
shell is used, as the end of the screw is liable to spring the shell and
displace the box. By means of the nut the box bearing is brought
to its proper place with very little trouble and in the most perfect
manner.
The cup is made slightly flaring from the shoulder of the spindle
upward, and this feature is found to be essential, as the oil will work up
an inclined surface by centrifugal motion, when it will remain stationary
in a chamber or on a surface with parallel sides.

filed by the said Alexander Melville Clark in the Great Seal Patent-
Office on the 27th May 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ALEXANDER
MELVILLE CLARK, of 53, Chancery Lane, in the County of Middlesex,
Patent Agent, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Second day of December, in the
year of our Lord One thousand eight hundred and seventy-two, in the
thirty-sixth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Alexander Melville Clark, Her special
licence that I, the said Alexander Melville Clark, my executors, admi.
nistrators, and assigns, or such others as I, the said Alexander
Melville Clark, 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 SPINDLE BOLSTERS OF SPINNING FRAMES," a com-
munication to me from abroad by Charles Franklin Wilson and Jesse
Edward Folk, both of the City of Brooklyn, County of Kings, and State
of New York, United States of America, upon the condition (amongst
others) that I, the said Alexander Melville Clark, 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 Alexander Melville Clark, 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 Sheet of
Drawings hereunto annexed, and to the letters and figures marked
thereon (that is to say) :-

the spindle as will prevent it from wearing, but such attempts have
hitherto been but partially successful.
This Invention is designed to accomplish the desired object, and
consists in a revolving cup and journal box within a shell, and in the
mode of confining the same in the rail of the spinning frame, the con-
struction and arrangement of parts being as herein-after described.
The accompanying Drawing represents a vertical central section
showing this improved spindle bearing attached to the rail. Similar
letters of reference indicate corresponding parts.
A is the spinning frame rail; B is the spindle; C is the shell which
surrounds the bearing box; D is the box; and E is the cup attached to
the spindle, which cup revolves in the annular space between the shell
and the box, as seen in the Drawing. The upper portion of the shell is
an oil reservoir. The top of the shell is formed to tightly inclose the
spindle without causing friction. F is an orifice for introducing oil. This
orifice is made with a punch, which leaves a lip G, which is turned in so
as to form a guard to the spindle when the oil is introduced. The oil
which is introduced into the chamber H runs down the spindle to the
bottom of the box, from whence it works into the cup E. The centrifugal
force now carries it up to the apertures J (one or more).

oil through the apertures and in contact with the bearing or spindle.
A constant circulation of the oil is thus kept up so that the spindle
constantly runs in oil. I, I, are apertures in the shell opposite the
orifices J. L is a nut which screws on to the shell beneath the rail and

remain stationary in a chamber or on a surface with parallel sides.
Having described the nature of the Invention and the manner in
which the same is to be performed, I declare that what I claim as the
Invention to be protected by the herein-before in part recited Letters
Patent is,
1st. In combination with a spindle and box the cup E, substantially
as shown and described for the purpose set forth.
2nd. The fastening nut L, substantially as and for the purposes
described.
3rd. A spindle bolster consisting of the shell C, box D, and cup E,
arranged substantially as described.
4th. The orifices I and J, and lips K, as and for the purposes set
forth.
5th. The orifice F, and lip. G, in combination with the shell of a
spindle bolster, substantially as and for the purposes described.
In witness whereof, I, the said Alexander Melville Clark, have
hereunto set my hand and seal, this Twenty-seventh day of May,
in the year of our Lord One thousand eight hundred and seventy-
three.
