the City of London, Patent Agent and Consulting Engineer, for the
Invention of "IMPROVEMENTS IN THE MEANS OR APPARATUS FOR LUBRI-
CATING VERTICAL SPINDLES OR SHAFTS IN SPINNING OR OTHER MACHINES."
-A communication from abroad by Victor Dubreuil, of Roubaix,
France.
Sealed the 29th July 1873, and dated the 4th February 1873.
PROVISIONAL SPECIFICATION left by the said John Clayton Mewburn
at the Office of the Commissioners of Patents, with his Petition,
on the 4th February 1873.
I, JOHN CLAYTON MEWBURN, of 169, Fleet Street, in the City of
London, Patent Agent and Consulting Engineer, do hereby declare the
nature of the said Invention for "IMPROVEMENTS IN THE MEANS OR
APPARATUS FOR LUBRICATING VERTICAL SPINDLES OR SHAFTS IN SPINNING OR OTHER
MACHINES," to be as follows :—
The inner part of the collars or bearings in which the spindles of
spinning machines are guided is always smooth, the result of which is

page_text: that after the operation of oiling the oil not being able to attach itself
to the spindle descends gradually of its own weight and soon becomes
spent or useless. This necessitates frequent oiling, and causes differ-
ences in the work, according as this work is produced at a lesser or
greater lapse of time after oiling. Now the object of the present
Invention is to obvinte this defect. The collar or bearing instead of
being smooth is formed with a screw thread which is internal in cases
where the collar or bearing is fixed, and external where the collar or
bearing itself rotates. This screw thread may extend the whole height
of the collar, or be only partial, and its direction, right handed or left
handed, is arranged according to the movement of the spindle or of the
collar, so that the helix of the screw thread in rising may be in the
direction of the movement of the spindle or collar. In this manner an
attractive force is created which tends to make the oil rise in the spirals.
The lubrication is consequently constant, and all the advantages of
permanent oiling are obtained.
SPECIFICATION in pursuance of the conditions of the Letters Patent
filed by the said John Clayton Mewburn in the Great Scal Patent
Office on the 30th July 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
CLAYTON MEWBURN, of 169, Fleet Street, in the City of London, Patent
Agent and Consulting Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fourth day of February, in the year
of our Lord One thousand eight hundred and seventy-three, in the thirty-
sixth year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said John Clayton Mewburn, Her special licence
that I, the said John Clayton Mewburn, my executors, administrators,
and assigns, or such others as I, the said John Clayton Mewburn, 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,

page_text: and vend, within the United Kingdom of Great Britain and Ireland,
the Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS
IN THE MEANS OR APPARATUS FOR LUBRICATING VERTICAL SPINDLES OR SHAFTS
IN SPINNING OR OTHER MACHINES," communicated to me from abroad by
Victor Dubreuil, of Roubaix, France, upon the condition (amongst
others) that I, the said John Clayton Mewburn, 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 John Clayton Mewburn, 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 :-
-
This Invention relates to means or apparatus for lubricating vertical
or nearly vertical spindles or shafts in spinning or other machines.
The inner sides of the collars or bearings in which the spindles of
spinning machines rotate are usually formed smooth, so that when the
lubrication is effected the oil gradually falls quickly down the said
spindles and disappears. The lubrication has therefore often to be
repeated, and the result of the working varies according as it is accom-
plished nearer or further from the time when the lubrication was effected.
The object of this Invention is to obviate the inconveniences above
pointed out, and its nature will be readily understood from the following
description:-The inner sides of the collars or bearings above mentioned
are formed with helical grooves instead of having smooth surfaces, and
these grooves extending from the top to the bottom of the collars or .
bearings, or for a part only of their surfaces, are so arranged with
relation to the movement of the spindles that the molecular attraction
will tend to keep the oil which in the old system quickly ran down in
the spirals of the grooves. For this purpose the direction of the
grooving is the right when the motion of the spindle is to the left, and
vice versa, and being thus rendered constant and self-acting the following
advantages will be obtained:-The machine will work more easily, the
torsion will be regular, the wear will be diminished, and the consumption
of oil will be reduced.

page_text: By means of this Invention the spindle of a machine rotating at the
speed of four thousand revolutions a minute may remain for a week
without the necessity of being again oiled, and the spindle of a self-
acting mill rotating at the speed of six thousand revolutions a minute
need only be oiled every two or three days if its collar or bearing is
suitably grooved according to this Invention.
The Invention is applicable to all spinning or other machines in which
cotton, jute, wool, flax, or silk is to be worked, and the grooving will of
course be modified according to the nature of the collars or bearings, tho
speed of the spindle, and the description of machines.
The Inventor has found by experience that from four to six grooves
in each collar gives good results. The grooving should preferably bo
square shaped; the full or non-grooved part should be about three-
quarters or four-fifths the width of the grooving; and the grooving should
be about a quarter or one-fifth deop, but these proportions are only given
as an example, and may be modified as circumstances may direct.
Having thus described the nature of the said Invention, and in what
manner the same is to be performed, I claim and desire to secure by the
said Royal Letters Patent, forming a helical groove in the inner or outer
sides of the collars, bearings, sockets, spinning spindles, or vertical or
nearly vertical shafts of all kinds of machines for lubricating purposes,
as above described and set forth.
In witness whereof, I, the said John Clayton Mowburn, have here-
unto set my hand and scal, this Thirtieth day of July, in
the year of our Lord One thousand eight hundred and seventy-
