page_text: LETTERS PATENT to Ephraim Smith. of Carlisle Street, in the County
of Middlesex, Goldsmith, for the Invention of "AN IMPROVEMENT IN THE

Sealed the 26th July 1861, and dated the 30th January 1861.
PROVISIONAL SPECIFICATION left by the said Ephraim Smith at the
Office of the Commissioners of Patents, with his Petition, on the 30th
January 1861.
I, EPHRAIM SMITH, of Carlisle Street, in the County of Middlesex,
Goldsmith, do hereby declare the nature of the said Invention of "AN IMPROVE.
WENT IN THE MANUFACTURE OF SWIVEL RINGS. ESPECIALLY APPLICABLE TO SWIVELS
AND WATCH KEYS," to be as follows:-
Mr Invention is intended to refer chiefly to swivels used for attaching
watches and other articles to guards and chains and to watch keys, and con-
sists in the means of securing the ring or eye to the body of the swivel or other
attic to which it is to be fixed, as hereafter explained. Hitherto the ring
Es secured by a pin or stud being passed through it and fastened by a
Washer or by an enlarged head or burr being formed on the end of the pin inside
the ring, or by both, the ring being free to swivel or turn round the pin. Now, I
contect the ring by a tang or tangs formed in a piece with, or united to it, and

page_text: depending therefrom, which I so fashion that on being placed inside the body,
the body may be pressed or closed thereon in such manner as to allow of the
tang or tangs swivelling or turning in the body without allowing it or them to
be withdrawn therefrom.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Ephraim Smith in the Great Seal Patent Office on the
30th July 1861.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, EPHRAIM
SMITH, of Carlisle Street, in the County of Middlesex, Goldsmith, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Thirtieth day of January, in the year of our Lord
One thousand eight hundred and sixty-one, in the twenty-fourth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said Ephraim Smith, Her special licence that I the said Ephraim Smith, my
executors, administrators, and assigns, or such others as I, the said Ephraim
Smith, 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 THE
MANUFACTURE OF SWIVEL RINGS, ESPECIALLY APPLICABLE TO SWIVELS AND WATCH
KEYS," upon the condition (amongst others) that I, the said Ephraim Smith,
my executors, or administrators, by an instrument in writing under my or
their, or one of their hands and seals, should particularly describe and ascer-
tain 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 1, the said Ephraim Smith, do hereby declare
the nature of my 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 thereof, reference being had to the Drawings hereunto annexed,
that is to say:-
My Invention is intended to refer chiefly to swivels used for attaching
watches and other articles to guards and chains and to watch keys, and con-

page_text: sists in the means of securing the ring or eye to the body of the swivel or other
article to which it is to be fixed, as hereafter explained. Hitherto the ring has
been secured by a pin or stud being passed through it, and fastened by a washer,
or by an enlarged head or burr being formed on the head of the pin inside the
ring, or by both, the ring being free to swivel or turn round the pin. Now, I
connect the ring by a tang or tangs formed in a piece with or united to it and
depending therefrom, which I so fashion that on being placed inside the body,
the body may be pressed or closed thereon in such manner as to allow of the
tang or tangs swivelling or turning in the body without allowing it or them to
be withdrawn therefrom.
Figure 1 of the accompanying Drawings is a view on an enlarged scale of
the ring and tang of a swivel, made in the manner before described; Figure 2
is a view of the body; and Figure 3 shows the tang fitted into the body and
pressed or closed up; Figure 4 is a view of a swivel partly in section, in which
the top of the body is made to form a tang, the ring being formed with a bell
or tube which is pressed in upon the tang, and within which the tang is free to
revolve; Figure 5 is a similar view of a swivel, in which the body embraces
the tang, the former being pressed or closed up as in the previous cases.
And having now described the nature of my said Invention and in what
manner the same is to be performed, I declare that I claim, the construction
of swivel rings with a tang or tangs inserted and secured in the body substan-
tially in manner and for the purpose herein-before described and illustrated in
the accompanying Drawings.
I also claim the modification shewn at Figure 4.
In witness whereof, I, the said Ephraim Smith, have hereunto set my
hand and seal this Thirtieth day of July One thousand eight hundred
EPH SMITH. (L.S.)
