IMPROVE- MENTS IN SPINNING MACHINERY
Year: 1864

page_text: LETTERS PATENT to Brice Wilkinson Barwick and William Hartley,
both of Keighley, in the County of York, for the Invention of "IMPROVE-
MENTS IN SPINNING MACHINERY."
PROVISIONAL SPECIFICATION left by the said Brice Wilkinson Barwick
and William Hartley at the Office of the Commissioners of Patents,
with their Petition, on the 23rd August 1864.
We, BRICE WILKINSON BARWICK and WILLIAM HARTLEY, both of Keighley,
in the County of York, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN SPINNING MACHINERY," to be as follows:-
Our Invention has reference to that part of the spinning frame known as
the front top roller, and has for its object the substitution of a roller more
readily manufactured, and more durable than those in ordinary use, possess-
ing in addition the property of greater "kindness" to the wool or other fibre
under operation.
Our improvements consist, firstly, in the use of one or more vulcanized
india-rubber or caoutchouc rings, instead of the cloth and leather now used.
This ring or these rings is or are supported by two discs (made of cast iron
by preference) baving flanges on their outer edges, and provided with centre
holes to receive the arbor or shaft, which is adapted as usual to carry
two rollers, and is furnished with collars towards the centre to retain the

page_text: inner discs in position, parts towards the outer end being screwed in order
that the outer flanged discs may by means of nuts on such screws be retained
in their position, and the india-rubber ring or rings be held tight between the
flanges; or the inner disc may be provided with a neck on the centre suffi-
ciently long to receive the outer disc, which in such caso has its centre
bored out to receive the neck, the end of which is screwed to receive a nut,
the two discs being tightened against the india-rubber or caoutchouc ring or
rings.
We thus obtain a front top roller which may readily be repaired and
nossessing the qualities before named.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Brice Wilkinson Barwick and William Hartley in the Great
Seal Patent Oflice on the 21st February 1865.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, BRICE
WILKINSON BARWICK and WILLIAM HARTLEY, both of Keighley, in the County
of York, send greeting.
WHEREAS er most Excellent Majesty Queen Victoria, by Iler Letters
Patent, bearing date the Twenty-third day of August, in the year of our Lord
One thousand eight hundred and sixty-four, in the twenty-eighth year of Her
eign, did, for Herself, Her heirs and successors, give and grant unto us,
the said Brice Wilkinson Barwick and William Hartley, Her special licence
that we, the said Brice Wilkinson Barwick and William Hartley, our exccu-
tors; administrators, and assigns, or such others as we, the said Brice Wil-
kinson Barwick and William Hartley, our 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, exerciso, and vend, within the United Kingdom of Great
Britain and Ireland, the Channel Islands, and Isle of Man, an Invention for
"IMPROVEMENTS IN SPINNING MACHINERY, "upon the condition (amongst others)
that we, the said Brice Wilkinson Barwick and William Hartley, our exc-
cutors or administrators, by an instrument in writing under our or their
hands and seals, or under the hand and seal of one of us or them, should
particularly describo and ascertain the nature of the said Invention, and
in what manner the same was to be performed, and cause the same to bo
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 we, the said Brice Wilkinson Barwick and William
Hartley, do hereby declare the nature of the said Invention, and in what
manner the saine is to be performed, to be particularly described and ascer-
tained in and by the following statement thereof, that is to say :—
Our Invention has reference to that part of the spinning frame known as
the front top roller, and has for its object the substitution of a roller moro
readily manufactured and more durable than those in ordinary use, possessing
in addition the property of greater "kindness" to the woo! or other fibre under
operation.
Our improvements consist, firstly, in the use of one or more vulcanized
india-rubber or caoutchouc rings, instead of the cloth and leather now in use.
This ring or these rings is or are supported by two discs (made of cast iron
by preference) having flanges on their outer edges, and provided with centre
holes to receive the arbor or shaft, which is adapted as usual to carry two
rollers, and is furnished with collars towards the centre to retain the discs in
position, the parts toward the outer end being screwed in order that the
outer flanged dises may by means of such screws be retained in their position,
and the india-rubber ring or rings be held tight between the flanges;
or the inner disc may be provided with a neck on the centre sufficiently
long to receive the outer disc, which in such a case bas its centre bored
out to receive the neck, the end of which is screwed to receive a nut,
the two discs being tightened against the india-rubber or caoutchouc ring or
rings as before.
We thus obtain a front top roller which may readily be repaired and
possessing the qualities before named.
This second plan, however, we do not regard as equal to the first, nor
so simple as some other methods illustrated on the accompanying Sheet
of Drawings, to which we refer for the better explanation of our Invention.
DESCRIPTION OF DRAWINGS.
Figure 1 is a front elevation, and Figure 2 a sectional view of a pair of
rollers mado on our improved plan, Figure 3 being a side elevation of
the same. Similar letters denote similar parts in the several Figures.
a is the arbor, carrying the discs b; c is the india-rubber or caoutchouc
ring, held firmly between the two discs 6 by means of the nut d, screwed on
the arbor a. It will be seen that the collars a' on the arbor keep the
rollers the required distance apart, and that the nuts d tighten the discs
against such collars. Figure 4 shows a front elevation and section of the

page_text: cheaper kind of roller, the rings being put upon solid iron dises b, which are
secured to the arbor by screws b'.
Figure 5 shows our Invention applied to an ordinary wooden disc without
flanges, the ring being put on tight, whilst Figure 6 shews the application of
a grooved wooden disc. The discs may be of wood, iron, or other suitable
material, and the rings secured by means of cement, if desired.
Having now shown and described the nature of our Invention, and in what
manner the same may be performed, although numerous modifications of our
improved rollers other than those shown may be introduced, we would have
it understood that, without confining ourselves to the precise details shewn,
we claim as our Invention the application of india-rubber or caoutchouc
rings for the purpose of spiuning substantially in the manner shown and
described.
In witness whereof, we, the said Brice Wilkinson Barwick and William
Hartley, have hereunto set our hands and seals, this Eighteenth day
of February, in the year of our Lord One thousand eight hundred and
sixty-five.
BRICE WILKINSON BARWICK. (L.S.)
WILLIAM HARTLEY.
