Year: 1861

page_text: LETTERS PATENT to George James Wainwright, Charles Timothy Brad-
bury, and John Lawton, all of Dukinfield, in the County of Chester, for
the Invention of "IMPROVEMENTS IN MACHINERY OR APPARATUS POR ROVING,
SLUBBING. OR SPINNING COTTON AND OTHER FIBROUS MATERIALS."
PROVISIONAL SPECIFICATION left by the said George James Wainwright,
Charles Timothy Bradbury, and John Lawton at the Office of the
Commissioners of Patents, with their Petition, on the 15th February
1861.
We, GEORGE JAMES WAINWRIGHT, CHARLES TIMOTHY BRADBURY, and JOHN
LAWTON, all of Dukinfield, in the County of Chester, do hereby declare the
nature of the said Invention for "IMPROVEMENTS IN MACHINERY OR APPARATUS
FOR ROVING, SLUBBING, OR SPINNING COTTON AND OTHER FIBROUS MATERIALS," to
be as follows:-
In the bolster, whether stationary or revolving, we form one or more holes
or openings placed in various parts, passing through to the spindle, so that the
oil or lubricating matter shall pass from one to the other. The interior of
the bolster can have circular grooves or hollows at the top, bottom, or other
suitable part, which may be packed or not, as required.

by the said George James Wainwright, Charles Timothy Bradbury, and
John Lawton in the Great Seal Patent Office on the 14th August
1861.
TO ALL TO WHOM THESE PRESENTS SHALL COME, wc, GEORGE
JAMES WAINWRIGHT, CHARLES TIMOTHY BRADBURY, and JOHN LAWTON, all of
Dukinfield, in the County of Chester, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fifteenth day of February, in the year of our Lord
One thousand eight hundred and sixty-one, in the twenty-fourth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto us,
the said George James Wainwright, Charles Timothy Bradbury, and John
Lawton, Her special licence. that we, the said George James Wainwright,
Charles Timothy Bradbury, and John Lawton, our executors, administrators,
and assigns, or such others as we, the said George James Wainwright,
Charles Timothy Bradbury, and John Lawton, our executors, administrators,
and assigns, should at any time agree with, and no others, from timo 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 MACHINERY OR APPARATUS FOR ROVING,
SLUBBING, OR SPINNING COTTON AND OTHER FIBROUS MATERIALS," upon the con-
dition (amongst others) that we, the said George James Wainwright, Charles
Timothy Bradbury, and John Lawton, our executors or administrators, by an
instrument in writing under our, 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 immo-
diately after the date of the said Letters Patent.
NOW KNOW YE, that we, the said George James Wainwright, Charles
Timothy Bradbury, and John Lawton, do hereby declare the nature of our
said Invention, and in what manner the same is to be performed, to be par-
ticularly described and ascertained in and by the following statement (that is
to say):-
In the bolster, whether stationary or revolving, we form one or more holes
or openings placed in various parts, passing through to the spindle, so that the
oil or lubricating matter shall pass from one to the other. The interior of

page_text: the bolster can have circular grooves or hollows at the top, bottom, or other
suitable part, which may be packed or not, as required.
These improvements will be clearly understood by referring to the figures
and letters on the accompanying Sheet of Drawings, in which Figs. 1, 2,
and 3 are vertical sections of various bolsters having our improvements applied
to them.
In Fig. 1 the spindle is represented at a, the bolster at b, and the outer.
lush, in which the bolster revolves, at c. The bolster is driven in, and:
attached to the bobbin braid d, for the convenience of removal when tho
wheels are worn out. In the bolster aro holes e, communicating between tho
spindle and the outer bush, for the purpose of lubrication, and at the top, as
at f, it is countersunk sufficiently to receive the ordinary supply of oil, which
descends to the holes e, and distributes itself over the outer and inner surfaces
of the bolster and bush. The lower part of the bolster is bevilled as at g,
and gives off the oil as it descends to the spindle, which, as it rises with the
lifting rail, carries the oil again to the holes e, through which it passes as
before, and distributes itself over the outer and inner surfaces of the bolster
and bush, which process is repeated until the oil is worked up; by this means
the upper portion of the spindle is kept free from oil, and thus preserves tho
bobbin from the usual accumulation of dirt.
In Fig. 2, the spindle a works in the bolster b, which is fixed to the
braid c, and revolves with it, turning in the stationary bush d. For the
reception of the oil the top of the bolster is countersunk, as at f, and for
its circulation there are in the bolster ono or more holes, as at g, and in
the stationary bush several holes, as at h and i. Oil is applied at the counter-
sink f. By the revolving of the spindle it passes through the holes g to tho
outside of the bolster, and then through the holes h to the outside of the busb,
and again opens on to the bolster 6 by the holes i. The bottom of the bolster
is bevilled, as at k, and gives off the excess of oil, which, by the rising of the
lifting rail and the revolution of the spindle, returns again by the holes,
as before described.
In Fig. 3, representing the ordinary stationary bolster, to which our improve-
ments are applied, a is the spindle; b, the bolster; c, the outer bush, to which
the bolster is fixed; d, the revolving braid; and e, f, holes, communicating
between the spindle and the braid, for the purpose of lubrication. The top of
the bolster is countersunk on both sides to receive the oil, and the flange g,
on which the braid revolves, is dished out for the same purpose. As the lifting
rail rises and falls, the oil circulates through the holes e, and again flowing to

page_text: the spindle through the holes f.. By all these arrangements the oil is used
over and over again until worked up, thus effecting a considerable saving in
oil and bobbins, and producing an improved quality of work.
Having now described the nature and particulars of our said Invention, and
the manner in which the same is to be performed, wo desire it to be under-
stood that we claim, in machinery or apparatus for roving, slubbing, or spinning
cotton and other fibrous materials the formation and employment of one or
more holes or openings placed in, various parts of the bolster and bush, for
the purpose of passing the oil or lubricating matter from one surface to
the other, as herein described and illustrated in the accompanying Sheet of
Drawings.
In witness whereof, we, the said George James Wainwright and Charles
Timothy Bradbury, for and on behalf of ourselves and the said John
Lawton, have hereunto set our hands and seals, this Thirteenth day.
of August, in the year of our Lord One thousand eight hundred and
sixty-one.

named George James Wainwright and
