page_text: LETTERS PATENT to Alfred Vincent Newton, of the Office for Patents,
66, Chancery Lane, in the County of Middlesex, Mechanical
Draughtsman, for the Invention of "IMPROVEMENTS IN THE CON-
STRUCTION OF RINGS FOR RING SPINNING."-A communication from
abroad by Cyrus Bullard Morse, of Rhinebeck, in the State of New
York, United States of America.
Sealed the 9th October 1868, and dated the 20th April 1868.
PROVISIONAL SPECIFICATION left by the said Alfred Vincent
Newton at the Office of the Cominissioners of Patents, with his
Petition, on the 20th April 1868.
I, ALFRED VINCENT NEWTON, of the Office for Patents, 66, Chancery
Lane, in the County of Middlesex, Mechanical Draughtsman, do hereby
declare the nature of the said Invention for "IMPROVEMENTS IN
STRUCTION OF RINGS FOR RING SPINNING." to be as follows:-
This improvement consists in part in providing rings for ring and
traveller spinning manufactured from tubes of highly carbonized cast
steel, the tubes being formed by a process whereby the metal is com-

close in texture to be susceptible of taking a smooth polish on its
surface and so uniform as to wear alike at all parts of the same.
The improvement further consists in part in an improved method
of manufacturing rings for ring and traveller spinning from tubular
metal.
The improvement also consists in part in providing for attaching the
rings to the ring rail in an adjustable manner, whereby a central position
of the spindle with reference to the ring may be more readily secured.
According to the first part of the Invention cylindrical tubes are
provided of highly carbonized cast steel which is submitted to great
pressure while in a molten state in the mould or to the centrifugal
action of high velocity in a rotary mould whereby the metal is very greatly
solidified and made homogeneous. From such stock rings of uniform
texture may be finished up without any previous forging, rolling, or
working in any manner and by reason of the metal being highly cat-
bonized they may be tempered in the wearing part at a very low heat
which is not so liable to cause the rings to become untrue by the undue
expansion consequent on a high degree of heat being required as in
low steel or as in the process of case hardening.
in
According to the second part of the Invention, a metal tube of suitable
internal and external diameter and of any convenient length is placed
any suitable hollow mandril, lathe, or machine with suitable mechanical
devices for holding the same while being operated upon and a finished
ring is formed on the end of the said tube and cut off before removing
or changing the tube in the lathe. After this the wearing portion of
the ring is tempered or hardened and the remaining portion being
protected by a composition of clay, alum, soapstone, or any other non-
conducting material remains untempered, the portion or parts to be
hardened or tempered being submerged in a lead bath or subjected
to other requisite processes for heating for tempering. The untempered
portion prevents the tempered or hardened portion from springing and
setting untruly in the act of hardening.
According to the third part of the improvement the rings are pro-
vided with ears or lugs, one on each side, on a line with the bottom
of the same, which are perforated with elongated openings whereby
they may be secured to the rail in an adjustable manner so that they
may be moved to adjust them with reference to the spindle. which

or according to another plan the lugs may be arranged on a separate
ring into which the travellers ring may be fitted and held by a
set screw.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Alfred Vincent Newton in the Great Seal Patent
Office on the 19th October 1868.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ALFRED
VINCENT NEWTON, of the Office for Patents, 66, Chancery Lane, in the
County of Middlesex, Mechanical Draughtsman, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twentieth day of April, in the year of
our Lord One thousand eight hundred and sixty-eight, in the thirty-
first year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Alfred Vincent Newton, Her special
licence that I, the said Alfred Vincent Newton, my executors, adminis-
trators, and assigns, or such others as I, the said Alfred Vincent
Newton, 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 "IMPROVEMENTS IN THE CONSTRUCTION OF RINGS FOR RING SPINNING," being
a communication to me from abroad, upon the condition (amongst others)
that I, the said Alfred Vincent Newton, 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 Alfred Vincent Newton, 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

page_text: in and by the following statement, reference being had to the Drawing
hereunto annexed, and to the letters and figures marked thereon (that
is to say)-
This improvement consists in part in providing rings for ring and
traveller spinning manufactured from tubes of highly carbonized cast
steel, the tubes being formed by a process whereby the metal is
compressed in the process of casting to render it homogeneous and
sufficiently close in texture to be susceptible of taking a smooth
polish on its surface and so uniform as to wear alike at all parts of
the same.
The improvement further consists in part in an improved method
of manufacturing rings for ring and traveller spinning from tubular
metal.
The improvement also consists in part in providing for attaching
the rings to the ring rail in an adjustable manner whereby a central
position of the spindle with reference to the ring may be more readily
secured.
Hitherto the method of making rings has been to take blanks of
iron or low steel formed by punching, forging, or swaging, or cut
from tubes at great labor and expense and after making the same
of suitable size and dimensions to form a ring to place the ring in
a chuck and bore the interior, then to drive it on a mandril to true
its edges and exterior, and again to place it in a chuck to be grooved
and finish it. After this it is case hardened in the usual way and
inserted into holes in the rail which may be and often are more
or less out of line with the spindles. Many serious objections to
placing a thin rough .uneven tubular blank in a chuck exist, among
which may be mentioned that it is forced out of its true shape so
that when taken out of the chuck it springs back to nearly its
original form, and driving it on to a mandril to turn it forces it out
of true again, also when driven off it springs again, and thus when
the ring is finished it is out of round to a greater or less extent;
moreover, when case hardened according to the present method these
inequalities of the ring in shape and thickness greatly tend to make
it more imperfect, causing it to make bad work and soon to wear.
unevenly, and become worthless.
According to the first part of the Invention cylindrical tubes are
provided of highly carbonized cast steel which is submitted to great

page_text: pressure while in a molten state in the mould or to the centrifugal
action of high velocity in a rotary mould whereby the metal is very
greatly solidified and made homogeneous. From such stock rings of
pretty uniform texture may be finished up without any previous
forging, rolling, or working in any manner, and by reason of the metal
being highly carbonized the rings may be tempered in the wearing
part at a very low heat, which is not so liable to cause the rings
to become untrue by the undue expansion consequent on a high degree
of lieat being required as. in low steel or as in the process of case
hardening.
According to the second part of the Invention a metal tube of
suitable internal and external diameter and of any convenient length
is placed in any suitable hollow mandril, lathe, or machine with
suitable mechanical devices for holding the same while being operated
upon and a finished ring is formed on the end of the said tube and
cut off after it is finished before removing or changing the tube in
the lathe. After this the wearing portion of the ring tempered or
hardened and the remaining portion being protected by a composition
of clay, alum, soapstone, or other non-conducting material remains
untempered, the portion or parts to be hardened or tempered being
submerged in a lead bath or subjected to other requisite processes
for heating for tempering. The untempered portion prevents the
tempered or hardened portion from springing and setting untruly in
the act of hardening.
According to the third part of the improvement the rings are
provided with ears or lugs, one on each side, on a line with the bottom
of the same, which lugs are perforated with elongated openings
whereby the rings may be secured to the rail in a manner that will
allow of their being moved to adjust them with reference to the spindle
which is liable to change position from time to time from various
causes: Or according to another plan the lugs may be arranged on a
separate ring into which the travellers ring may be fitted and held
by a set screw.
In the accompanying Drawings, Fig. 1 represents à plan view of
a ring constructed according to this Invention and provided with an
adjustable holder; Fig. 2 is a sectional elevation of the same, and
Fig. 3 represents a finished ring previous to being cut from the end
of the tube from which it has been manufactured,
