AN IMPROVEMENT IN MACHINERY USED FOR SPINNING AND DOUBLING COTTON AND OTHER FIBROUS SUBSTANCES
Year: 1870

page_text: LETTERS PATENT to Benjamin Brown, Manager to Messrs. Walker
and Hacking, of Vulcan Works, Bury, in the County of Lancaster;
for the Invention of "AN IMPROVEMENT IN MACHINERY USED FOR SPINNING
AND DOUBLING COTTON AND OTHER FIBROUS SUBSTANCES."
Sealed the 29th March 1870, and dated the 8th January 1870.
PROVISIONAL SPECIFICATION left by the said Benjamin Brown at
the Office of the Commissioners of Patents, with his Petition, on
the 8th January 1870: --
!
I, BENJAMIN BROWN, Manager to Messrs. Walker and Hacking, of
5 Vulcan Works, Bury, in the County of Lancaster, do hereby declare.
(the nature of the said Invention for "AN IMPROVEMENT IN MACHINERY
USED FOR SPINNING AND DOUBLING COTTON AND OTHER FIBROUS SUBSTANCES," to
be as follows: —
This Invention is designed principally to be applied to those machines
0 O known as "throstles" and "doublers" used for spinning and doubling
cotton, but it is also equally applicable to such machines used for,

page_text: spinning and doubling silk and other fibrous substances wherein the
spindles revolve in bushes or collars passing through a lifting rail, the
top plate of which supports the bobbins, a drag or washer cloth being
interposed between the bobbins and the said plate. A great defect
in these machines has hitherto been that the fibrous edges of the holes
in the washer cloth through which the spindles pass soak up the oil,
and hence the bushes or collars require frequent oiling, and thus
time and oil are both wasted, and the washer cloths were likely to get
displaced in raising and lowering the said rail when oiling.
My improvement is intended to obviate this defect, and consists
principally in casting or otherwise forming; a rim or collar round each
spindle hole in the said top plate of the lifting rail, the said rim or
collar being raised a certain distance above the level of the same, so
that the holes in the washer cloth fit round the said collars, and hence
the washer cloth itself does not touch the spindle and cannot absorb
the oil. By this means I am enabled to prolong the spindle bush or
collar upwards, which by lengthening the bearing will cause the spindles.
to run much steadier and at a greater speed. When the top plate
is raised for oiling the spindle bushes it takes the washer cloth and
bobbins with it, and both in ascending and descending the rims or
collars keep the fibrous edges of the holes in the washer cloth from
contact with the spindles, and hence the washer cloth cannot absorb
the oil and is not liable to be displaced in either ascending or descending,
The said raised rims may be either cast in one piece with the top plate
of the lifting rail, or the spindle holes may be bored out rather larger 2
and the rims inserted in the form of bushes.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Benjamin Brown in the Great Seal Patent Office
on the 7th July 1870.

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, BENJAMIN 30
BROWN, Manager at Messrs. Walker and Hackings, of Vulcan Iron
Works, Bury, in the County of Lancaster, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Eighth day of January, in the year
of our Lord One thousand eight hundred and seventy, in the thirty-third 35

page_text: year of Her reign; did, for Herself, Her heirs and successors, give and
grant unto me, the said Benjamin Brown, Her special license that I,
the said Benjamin Brown, my executors, administrators, and assigns, or
such others as I, the said Benjamin Brown, 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 "AN IMPROVEMENT IN MACHINERY USED FOR SPINNING
AND DOUBLING COTTON, SILK, AND OTHER FIBROUS SUBSTANCES," upon the con-
dition (amongst others) that I,the said Benjamin Brown, 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 Benjamin Brown, 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 and accompanying Drawings (that is to say):
·
"
This Invention is designed' principally to be applied to those machines
known as
throstles and "doublers," used for spinning, and doubling
cotton, but it is also equally applicable to such machines used for spinning
and doubling silk and other fibrous substances wherein the spindles
revolve in bushes or collars passing. through a. lifting rail, the top
plate of which supports the bobbins, a drag or washer cloth being
interposed between the. bobbins and the said plate. A great defect
in these machines has hitherto been that the fibrous edges of the
holes in the washer cloth through which the spindles pass soak up .the
oil, and hence the bushes or collars require frequent oiling, and thus
time and oil are both wasted, and the washer cloths were likely to get
displaced on raising and lowering the said rail when oiling.
My improvement is intended to obviate this defect, and consists
principally in casting or otherwise forming a rim or collar round each
spindle hole in the said top plate of the lifting rail, the said rim or
collar being; raised a certain distance above the level of the same, so
that the holes in the washer cloth fit round the said collars; and hence

page_text: the washer cloth itself does not touch the spindle, and cannot absorb
the oil. By this means I am enabled to prolong the spindle bush or
collar upwards, which by lengthening the bearing will cause the spindles
to run much steadier and at a greater speed. When the top plate
is raised for oiling the spindle bushes it takes. the washer cloth and
bobbins with it, and both in ascending and descending the rims or
collars keep the fibrous edges of the holes in the washer cloth from
contact with the spindles, and hence the washer cloth cannot absorb the
oil and is not liable to be displaced in either ascending or descending.
The said raised ring may be either cast in one piece with the top plate
of the lifting rail, or the spindle holes may be bored out rather larger
and the rims inserted in the form of bushes.
Such being the nature and object of my said Invention for. "An
Improvement in Machinery used for Spinning and Doubling Cotton,
Silk, and other Fibrous Substances," I will now proceed to describe
more in detail the manner in which the same is to be or may be per-
formed or carried into practical effect, and in order that the same may
be clearly understood, I have annexed hereunto a Sheet of Drawings
illustrative thereof, and have marked the same with figures and letters
of reference corresponding with those in the following explanation
thereof.
P
Fig. 1 represents an elevation of an ordinary throstle spindle drawn
about two-thirds of full size with the spindle rail, lifting rail, bush and
bobbin shown in section, and Fig. 2 is a cross section of the lifting rail,
top rail, and bush drawn full size and clearly illustrating my Invention.
a, a, is the spindle; b, b, the bobbin; c, c, the spindle rail; and d, d,
the lifting rail. The top rail e, e, of this lifting rail is cast or formed
with a rim or collar f;f, round each spindle hole (see Fig. 2), which is
raised above the level of the same a certain distance so that the holes
in the washer cloth g, g, fit round the collars and are kept clear of the
bush h, h, and of the spindle when the bobbins are lifted for oiling, as
shown at Fig. 4 in the Drawing. Fig. 3 shows the method of adapting
my Invention to an old rail by boring out the spindle holes in the
rail e, e, rather larger and inserting the rims f, f, in the form of
bushes.
Having now described the nature and object of my said Invention,
together with the manner in which the same is to be or may be per-
formed or carried into practical effect, I wish it to be understood that

page_text: I claim as my Invention, casting, or forming a raised rim or collar
round the spindle holes of the lifting rail or top rail of a throstle,
substantially in the manner and for the purposes above more particularly
described and illustrated by the Drawings annexed.
In witness whereof, I, the said Benjamin Brown, have hereunto
set my hand and seal, this Fifth day of July, in the year of
our Lord One thousand eight hundred and seventy.
BENJAMIN BROWN. (L.s.)
