CERTAIN IMPROVEMENTS IN MACHINERY OR APPARATUS EMPLOYED IN SPINNING COTTON, WOOL, SILK AND OTHER FIBROUS SUBSTANCES
Year: 1861

page_text: LETTERS PATENT to Benjamin Brown, of Bury, in the County of Lancaster,
Mechanic, and Richard Hacking, of the same Place, Machine Maker,
for the Invention of "CERTAIN IMPROVEMENTS IN MACHINERY OR APPARATUS
EMPLOYED IN SPINNING COTTON, WOOL, SILK AND OTHER FIBROUS SUBSTANCES."
Sealed the 21st January 1862, and dated the 25th July 1861.
PROVISIONAL SPECIFICATION left by the said Benjamin Brown and
Richard Hacking at the Office of the Commissioners of Patents, with
their Petition, on the 25th July 1861.
We, BENJAMIN BROWN, of Bury, in the County of Lancaster, Mechanic, and
RICHARD HACKING, of the same Place, Machine Maker, do hereby declare
the nature of the said Invention for "CERTAIN IMPROVEMENTS IN MACHINERY
OR APPARATUS EMPLOYED IN SPINNING COTTON, WOOL, SILK, AND OTHER FIBROUS
SUBSTANCES," to be as follows:-
Our Invention applies to a certain description or manufacture of spinning
machines called "throstles" or "throstle frames," in which a horizontal "rack"
and pinion or toothed wheel is employed in connection with the ordinary "heart
wheel" for effecting the lift of the "copping rail," in order to regulate the
winding of the yarn on to the bobbins.
Hitherto this "rack," which extends across the "throstle" and operates
upon the copping motion on each side, that is, upon each set or row of spindles,

page_text: has been formed all in one piece or casting, and having the rack teeth cast
with it, whereas our improvement consists in so arranging this motion that
the regularity and certainty of the lift of the "copping rail" may be effected
to the utmost by simply having the "racks" of teeth made separate and
independant of their carrying or supporting bar or rail, being attached thereto
by a screw bolt, capable of sliding in a groove or slot in such bar or rail, and
adjusted by means of a horizontal screw and nut at the outer ends, so that by
the slightest turn of which said screws the "racks" may operate upon the
copping motion, and regulate the "lift" of the "copping rail," as required.
SPECIFICATION-in-pursuance of the conditions of the Letters Patent, filed
by the said Benjamin Brown and Richard Hacking in the Great Seal
Patent Office on the 25th January 1862.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, BENJAMIN
BROWN, of Bury, in the County of Lancaster, Mechanic, and RICHARD HACKING,
of the same Place, Machine Maker, send greeting..
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-fifth day of July, in the year of our Lord One
thousand eight hundred and sixty-one, in the twenty-fifth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto us,
the said Benjamin Brown and Richard Hacking, Her special license that
we, the said Benjamin Brown and Richard Hacking, our executors, adminis-
trators, and assigns, or such others as we, the said Benjamin Brown and
Richard Hacking, our executors, administrators, and assigns, should at any
time agree with, and no others, from time to time and at all times there-
after 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 "CERTAIN
IMPROVEMENTS IN MACHINERY OR APPARATUS EMPLOYED IN SPINNING COTTON, WOOL,
SILK, AND OTHER FIBROUS SUBSTANCES," upon the condition, amongst others,
that we, the said Benjamin Brown and Richard Hacking, by an instrument
in writing under our hands and seals, or under the hand and seal of one of us,
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.

page_text: 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 per-
formed, to be particularly described and ascertained in and by the following
statement and accompanying Drawings (that is to say):-
"
Our Invention applies to a certain description or manufacture of spinning
machines called "throstles" or "throstle frames," in which a horizontal
"rack" and pinion or toothed wheel is employed in connection with the
ordinary "heart wheel" for effecting the lift of the "copping rail "in order to
Hitherto this rack,"
regulate the winding of the yarn on to the bobbins.
which extends across the "throstle," and operates upon the copping motion on
each side, that is, upon each set or row of spindles, has been formed all in one
piece or casting, and having the rack teeth cast with it, whereas our improve-
ment consists in so arranging this motion that the regularity and certainty of
the lift of the "copping rail "may be effected to the utmost by simply having
the "racks" of teeth made separate and independent of their carrying or
supporting bar or rail, being attached thereto by a screw bolt capable of sliding
in a groove or slot in such bar or rail, and adjusted by means of a horizontal
screw and nut at the outer ends, so that by the slightest turn of which said
screws the "racks" may operate upon the copping motion, and regulate the
"lift" of the "copping rail," as required.
In order that the Invention may be better understood and explained in
detail, I have hereunto attached a Sheet of Drawings made about half the
real size, illustrative of the peculiar formation of the rack, and a sectional view
of part of a "throstle" frame, shewing its application, drawn about four inches
to a foot, similar letters of reference being marked upon corresponding parts.
Figs. 1, 2, and 3, represent respectively a plan, sectional, and back view of
the improved construction of "rack;" and Fig. 4 shews the application of the
same to the copping rail. In the various Figures a, a, is the bar upon which
the plates of teeth b, b, are fitted and secured by the bolt c, c, passing through
slots therein, the regulation of the "racks" being adjusted by means of the
screws d, d. The object, desired to be effected by forming the rack so as to be
adjustable is the regulation of the "lift" of the copping rail in order to adjust
the bobbins with regard to the flyers, so that the yarn may be properly wound
on the barrel of the bobbin.
Having now described the nature of the said Invention, together with the
method of carrying the same into practical effect, I would remark, in con-
clusion, that I claim the regulation of the "lift" of the copping rail for
adjusting the height of the bobbins in throstles, and similar machinery, by the

page_text: employment and use of an adjustable rack, in contradistinction to the rigid
or unadjustable form at present in use, as herein-before described, set forth,
and fully illustrated in the Drawings attached.
In witness whereof, I, the said Benjamin Brown, have hereunto set my
hand and seal, this Twenty-fourth day of January, in the year of our
Lord One thousand eight hundred and sixty-two.
BENJN. BROWN. (L.S.)
