Year: 1870

page_text: LETTERS PATENT to Henry Manton and James Henry Mole, both
of Birmingham, in the County of Warwick, Goldsmiths, for the
Invention of "IMPROVEMENTS IN SWIVELS."
Sealed the 30th August 1870, and dated the 15th March 1870.
PROVISIONAL SPECIFICATION left by the said Henry Manton and
James Henry Mole at the Office of the Commissioners of Patents,
with their Petition, on the 15th March 1870.
'WC, HENRY MANTON and JAMES HENRY MOLE, both of Birmingham,
in the County of Warwick, Goldsmiths, do hereby declare the nature of
the said Invention for "IMPROVEMENTS IN SWIVELS," to be as follows: :―
Our Invention consists of the improvements hercin-after described in
swivels, the said improvements being specially applicable to swivels for
watch guards or chains, locket chains, and other like chains, but are also
applicable to chains for other purposes.
Our Invention relates to that part of swivels called the loop, that is,
the rotating ring at the head of the swivel, to which ring the guard or

page_text: "
other chain is attached; and our said Invention consists in constructing
the said loop and attaching it to the body of the swivel in the manner
herein-after explained, whereby great security in the attachment of the
loop to the body of the swivel is obtained combined with neatness of
appearance.
According to our Invention we provide the loop of the swivel with a
shank or stem, and place upon the said shank or stem a perforated
collar or ring. We then fix the collar to the shank or stem by rivetting
or expanding the end of the shank or stem or forming thereon or
attaching thereto a head. The collar is by this means fixed to the loop,
but the said loop is capable of rotating in the said collar. That part of
the collar nearest the rivitted end of the stem is of less diameter than
the other part, a shoulder being thus formed at the junction of the two
parts. The combined loop and collar is attached to the body of the
swivel by soldering; that is to say, the body of the swivel is hollow or
tubular and receives the rivetted end of the stem and also the reduced
part of the collar, which reduced part of the collar accurately fits the
hollow of the body, the shoulder at the said reduced part resting on the
top of the tubular body. When the collar of the swivel loop has been
fitted in the top of the tubular body of the swivel the said collar is
soldered to the said body. The loop is thus fixed very securely to the
body of the swivel while it is free to rotate upon the said body.
The inside of the loops of swivels made according to our Invention are

filed by the said Henry Manton and James Henry Mole in the
Great Scal Patent Office on the 10th September 1870.
TO ALL TO WHOM THESE PRESENTS SHALL COME, wc, HENRY
MANTON and JAMES HENRY MOLE, both of Birmingham, in the County
of Warwick, Goldsmiths, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fifteenth day of March, in the year
of our Lord One thousand eight hundred and seventy, in the thirty-
third year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto us, the said Henry Manton and James Henry Mole, Her

special licence that we, the said. Henry Manton and James Henry Mole,
our executors, administrators, and assigns, or such others as we, the
said Henry Manton and James Henry Mole, our executors, adminis-
trators, 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 SWIVELS,"
upon the condition (amongst others) that we, the said Henry Manton
and James Henry Mole, our executors or administrators, by an instru-
ment in writing under our or their hands and seals, or under the hand
and scal of one of us or them, 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 James Henry Mole, on behalf of
the said Henry Manton and myself, 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
thereof, that is to say :-
Our Invention consists of the improvements hercin-after described in
swivels, the said improvements being specially applicable to swivels for
watch guards or chains, locket chains, and other like chains, but are also
applicable to swivels for other purposes.
Our Invention relates to that part of swivels called the loop, that is,
the rotating ring at the head of the swivel, to which ring the guard
or other chain is attached; and our said Invention consists in con-
structing the said loop and attaching it to the body of the swivel in the
manner herein-after explained, whereby great security in the attachment
of the loop to the body of the swivel is obtained combined with strength
and neatness of appearance.
According to our Invention we provide the loop of the swivel with a
shank or stem, and place upon the said shank or stem a perforated collar
5 or ring. We then fix the collar to the shank or stem by rivetting or
expanding the end of the shank or stem, or forming thereon or attaching
thereto a head. The collar is by this means fixed to the loop, but the
said loop is capable of rotating in the said collar. That part of the

page_text: collar nearest the rivetted end of the stem is of less diameter than the
other part, a shoulder being thus formed at the junction of the two
parts. The combined loop and collar is attached to the body of the
swivel by soldering; that is to say, the body of the swivel is hollow or
tubular, and receives the rivetted end of the stem, and also the reduced
part of the collar, which reduced part of the collar accurately fits the
hollow of the body, the shoulder at the said reduced part resting on the
top of the tubular body. When the collar of the swivel has been fitted
in the top of the tubular body of the swivel the said collar is soldered to
the said body; the loop is thus fixed very securely to the body of the
swivel while it is free to rotate upon the said body.
Having explained the nature of our Invention, we will proceed to
describe, with reference to the accompanying Drawing, the manner in
which the same is to be performed.
Figure 1 represents in front and side elevation a watch chain or other
swivel the loop of which is made and connected to the body of the
swivel according to our Invention; Figure 2 represents a section of the
swivel drawn to a larger scale; Figure 3 is a portion of Figure 2;
Figures 4, 5, 6, and 7 represent the parts of which the swivel is
composed separately. The same letters of reference indicate the same 2
parts in each of the Figures of the Drawings.
a is the tubular body of the swivel; and b is the hook of the same;
c is the rotating loop of the swivel provided with a stem c³; d is the
collar or ring to which the loop c is connected.
In connecting the loop c to the body a we proceed as follows:-We
take the loop, Figure 4, and place upon the stem c³ of the said loop the
collar or ring d, and against the bottom end of the reduced part of the
said collar d we place a ring or washer e. The parts now occupy the
positions represented in Figure 3. By next rivetting or expanding
the end of the stem c² against the washer e the loop c is connected to 3
the collar d, but the said loop c is free to rotate in the said collar, the
washer e on the rotation of the loop c bearing against the bottom of the
reduced part of the collar d. The ring or washer e may be dispensed
with, and the end of the stem of rivetted or expanded against the bottom
of the collar, but we prefer to use the said washer. Instead of making a 3
head or expanded part from the stem itself a separate head may be
soldered or fixed to the stem for the purpose of retaining the collar d on
the said stem. The loop c thus connected to the collar dis secured to

page_text: the tubular body a of the swivel in the manner represented in Figure 2,
that is to say, the reduced part of the collar d is placed within the
tubular body a, so that the said collar rests by its shoulder on the top of
the said body. The collar d is then soldered or otherwise fixed to the
body, and the loop c thereby secured in its place, but is free to rotate
upon the said body. The inside of the rotating loop c of the swivel is by
our Invention without the unsightly projecting head which swivel loops
of the ordinary kind possess, the projecting head being concealed within
the body of the swivel. By connecting the rotating loop to the body
according to our Invention the metal of the body where the loop is
connected to it is of great strength, and the connection is stronger than
when the body is attached to the loop by spinning or burnishing a thin
body on to the loop.
Having now described the nature of our Invention, and the manner
in which the same is to be performed, we wish it to be understood that
we do not limit ourselves to the precise details herein described and
illustrated, as the same may be varied without departing from the nature
of our Invention; but we claim as our Invention the improvements in
making and attaching the loops or rotating rings of swivels to the bodies
of the said swivels herein-before described and illustrated in the accom-
panying Drawing, that is to say, first, connecting the rotating loop or
ring of the swivel to a perforated collar, and afterwards securing the
combined loop and collar to the body of the swivel by soldering or fixing
the said collar to the tubular body of the swivel, substantially as herein
described and illustrated.
In witness whereof, I, the said James Henry Mole, have here-
unto set my hand and scal, this Second day of September, in
Witness,

Clerk to George Shaw,
Birmingham.
