page_text: LETTERS PATENT to Thomas Winkles and Thomas Moxon, both of Birmingham,
in the County of Warwick, for the Invention of CERTAIN IMPROVEMENTS IN
SWIVELS FOR SECURING WATCHES TO THEIR CHAINS, ALSO APPLICABLE TO OTHER
ANALOGOUS PURPOSES.”
Sealed the 10th April 1879, and dated the 14th October 1878.
PROVISIONAL SPECIFICATION left by the said Thomas Winkles and Thomas
Moxon at the Office of the Commissioners of Patents on the 14th October
1878.
"
THOMAS WINKLES and THOMAS Moxon, both of Birmingham, in the County of
Warwick. CERTAIN IMPROVEMENTS IN SWIVELS FOR SECURING WATCHES TO THEIR
CHAINS, ALSO APPLICABLE TO OTHER ANALOGOUS PURPOSES."
The object of this Invention is to produce a swivel which shall be simple in its
construction, and at the same time be capable of more securely locking or connecting
the articles to which it may be applied than can be done by the olden method.
Our Invention consists substantially of the following arrangements of parts :—A
base plate, to the upper part of which is connected the ring (or swivel proper), this
being permanently affixed to the chain. To the base of the said plate is arranged
the loop or bow for receiving the watch, working upon a pin freely in either
desired direction, the end of the said bow being formed as a fastener with a corre-
sponding indent or recess for receiving the same in the side of the base plate (in
mechanism this fastening is designated a bayonet catch). To the one side of the
said plate is a second plate moveable somewhat, corresponding in form and working
upon a pin, so that when the fastener of the bow enters the recess this second
plate is moved over; a most secure fastening is thus afforded; the springs hitherto
employed, so complicated and liable to disarrangement, are here dispensed with.

THOMAS WINKLES and THOMAS MOXON, of Birmingham, in the County of

The object of this Invention is to produce a swivel which shall be simple in its
construction, and at the same time be capable of more securely locking or connecting
the articles to which it may be applied than can be done by the olden method.
Our Invention consists substantially of the following arrangements of parts:-A
base plate, to the upper part of which is connected the ring (or swivel proper), this
being permanently affixed to the chain. To the base of the said plate is arranged
the loop or bow for receiving the watch working upon a pin freely in either desired
direction, the end of the said bow being formed as a fastener with a corresponding
indent or recess for receiving the same in the side of the base plate (in mechanics
this fastening is designated a bayonet catch). To the one side of the said plate is a
second plate moveable somewhat, corresponding in form and working upon a pin,
so that when the fastener of the bow enters the recess this second plate is moved
over; a most secure fastening is thus afforded. The springs hitherto employed, so
complicated and liable to disarrangement, are here dispensed with.
And in order that this our said Invention may be fully understood, we shall now
proceed more particularly to describe the same, and for that purpose shall refer to
the accompanying Sheet of Drawings, and to the letters of reference indicated
thereon.
Fig. 1 represents a front view in elevation of a swivel open; Fig. 2, the same closed.
Fig. 3 is also a view in elevation and open; Fig. 4, the same closed.
The same letters of reference indicate the same parts.
a
"
a is the base plate carrying the pin b, upon which rotates the ring c; d is the
loop or bow, the one end of which is connected or pivotted to ".
at that part
indicated at e, and is moveable in one direction lateral by reference to Fig. 1; this
is clearly shewn and prepared to receive the article it is intended for. The other
end of the loop or bow & is studded with a projection f for the purpose of fitting
in a corresponding indent or recess in the base plate a and marked g; h is a plate
working upon a pin at i, and moving in either desired direction, the object of the
said plate being to allow the removal of d, the articles placed thereon, and then
returned to its normal position. The plate h is then brought back again as shewn
by Fig. 2, and a simple and efficacious fastening is thus obtained.
In Fig. 3 and 4 a is the body, in form somewhat circular; b is the pin, upon
which rotates the ring c; d is the loop or bow, the one end of which is pinned or
jointed to that part of the bedy a marked e. To the other end of the loop or bow d
is arranged a projecting catch f. At the base of the body a is a groove, into which
is fitted the ring g, having the loop h, the said ring g rotating in either desired
direction, the object of which is that upon moving the said ring g until the loop h
is immediately opposite to the projecting catch of the loop or bow d, when the
said bow can be released and its purpose effected as shewn at Fig. 3. The bow or
loop d can then again be closed, the ring g removed, until the loop h passes the
projecting catch f, as shewn by reference to Fig. 4, a secure fastening being thus
effected.
Our improved swivels may be made of any suitable metal or material, and be of
any shape or design to suit its innumerable applications, but we may mention that
of securing watches to their chains, to parts of harness, furniture, keys, dog and
other chains; also to bags, satchells, and other like purposes.
Having now described and ascertained the nature of this our said Invention, and the
manner in which the same is or may be performed, we would observe in conclusion

page_text: that we do not limit ourselves to the precise details herein given and shewn on
the accompanying Drawings, as various modifications may be made therein, while
retaining the essential features of our said Invention, but what we claim as new
and desired to be secured to us by the herein-before in part recited Letters Patent
is, "the novel arrangement and combination of parts together forming our improve-
ments in swivels for securing watches to their chains,' which said improvements
are also applicable to other analogous purposes, substantially as herein-before
described and shewn on the Drawings.

In witness whereof, we, the said Thomas Winkles and Thomas Moxon, have
hereunto set our hands and seals, this Tenth day of April, in the year of
our Lord One thousand eight hundred and seventy-nine.
