PROVISIONAL SPECIFICATION.
Improvements in Swivels for Chains, Cuff Links, Bags, Straps, and
other Articles.
I HENRY EDMONDS of No. 38 Radnor Road, Handsworth in the County of
Stafford, Jeweller do hereby declare the nature of this invention to be as
follows:-
My invention consists in constructing and arranging in the manner hereinafter
described the parts of swivels for chains, cuff links, bags straps and other articles,
whereby the opening of the bows of the swivels is facilitated and the manufacture
of the swivels simplified and ecouomised.
Instead of opening and closing the bow of the swivel by means of a spring closed
jointed tongue piece on the bead or collar of the swivel, as usual, I use a closing
tongue piece capable of a sliding motion to and from the open side of the bow for
opening and closing it; and 1 make the bow, its stem and the eye of the swivel
and a spring snap fastening for retaining the sliding tongue piece in its closing
position from one piece of wire as hereinafter described.
In constructing a swivel according to my invention I solder or otherwise fix to
the hollow bend or collar of the swivel, an inclined tongue piece which when
advanced by the bend or collar towards the bow closes the gap or opening in and
completos the said bow and thereby connects the swivel to the chain or other
article with which it is used. The bead or collar carrying the sliding tongue
piece, works upon the stem of the swivel and the lower half of the stem is provided
with a short limb which constitutes a spring snap fastening which snaps upon the
lower edge of the hollow bead or collar when the sliding tongue piece has reached
its closing position and thereby retains the said tongue pieco in its place for closing
the bow. By pressure upon the bead or collar it is disengaged from the spring
soap fastening and the sliding tongue piece may be withdrawn to open the bow.
In this way the opening and closing of the bow of the swivel is very readily effected
by the sliding of the head or collar upon the stem.
lu making the combined bow, stem, eye and spring soap fastening, 1 take a piece
of wire and double it upon itself near one end for a short distance and make from
the doubled end at the bend the eye of the stem and the spring snap fastening.
Upon the doubled part of this wire, which constitutes the stem of the finished bow,
the hollow bead or collar carrying the sliding tongue piece is threaded and the
part of the wire above the doubled part and bead, is bent into the open sided bow,
a aboulder at the junction of the bow with the top of the stem acting as a stop to
limit the advance of the sliding tongue piece to close the bow.

other Artioles.
I, HENRY EDMONDS, of No. 38 Radnor Road, Handsworth, in the County of
Stafford, Jeweller, do hereby declare the nature of my invention and in what
manner the same is to be performed to be particularly described and ascertained in
and by the following statement :-
My invention consists in constructing and arranging in the manner hereinafter
described the parts of swivels for chains, cuff-links, bags, straps and other articles,
whereby the opening of the bows of the swivels is facilitated and the manufacture
of the swivels simplified and economised.
Instead of opening and closing the bow of the swivel by means of a spring closed
jointed tongue piece on the bead or collar of the swivel as usual, I use a closing
tongue picce capable of a sliding motion to and from the open side of the bow for
opening and closing it; and I make the bow, its stem and the eye of the swivel
and a spring snap fastening for retaining the sliding tongue piece in its closing
position from one piece of wire as hereinafter described.
In constructing a swivel according to my invention I solder or otherwise fix to
the hollow bead or collar of the swivel an iuclined tongue piece which when
advanced by the bead or collar towards the how closes the gap or opening in
and completes the said bow and thereby connects the swivel to the chain or
other article with which it is used. The bead or collar carrying the sliding
tongue piece, works upon the stem of the swivel and the lower half of the stem
is provided with a short limb which constitutes a spring snap fastening which
snaps upon the lower edge of the hollow bead or collar when the sliding tongue
piece has reached its closing position and thereby retains the said tongue piece
in its place for closing the bow. By pressure upon the bead or collar it is
disengaged from the spring snap fastening and the sliding tongue piece may be
withdrawn to open the bow. In this way, the opening and closing of the bow
of the swivel is very readily effected by the sliding of the bead or collar upon
the stem.
In making the combined bow, stem, eye and spring snap fastening, I take a
piece of wire and double it upon itself near one end for a short distance and
make from the doubled end at the bend, the oye of the stem and the spring snap
fastening. Upon the doubled part of this wire, which constitutes the stem of the
finished bow, the hollow bead or collar carrying the sliding tongue piece is
threaded and the part of the wire above the doubled part and bead, is bent into
the open sided bow or into a closed bow, a shoulder at the junction of the bow
with the top of the stem acting as a stop to limit the advance of the sliding
tongue piece to close the bow.
I will now proceed to describe with reference to the accompanying drawing the
manner in which my invention is to be performed.
In order that the construction and action of my invention may be the better
understood I have shown my improved swivels drawn to a large soale.
Figures and 2 represent a swivel for a chain or other article constructed
according to my invention, Figure 1 showing the bow closed by the sliding tongue
piece and Figure 2 showing the bow opened by the withdrawal of the said sliding
tongue piece;
Figure 3 is a cross section of the swivel taken on the line A A Figure 1 and
Figure 4 represents the body of the swivel without the hollow bead or collar

page_text: and before the tongue piece is separated from the bow part of the swivel as
hereinafter described.
The same letters of reference indicate the same parts.
b is the bow of the swivel; o is the stem and e the short limb of the stem,
constituting the spring snap fastening, for retaining the hollow bead or collar f
carrying the sliding tongue piece g. The said hollow bead or collar f slides apon
the stem c, e aud when in the advanced position Figure 1 the sliding tongue piece g
fixed to it closes the gap or opening hin and completes the bow b and thereby
connects the swivel to the article with which the swivel is to be used; and when
the sliding tongue piece g is in the withdrawn position Figure 2 the article may
be connected to or withdrawn from it. In advancing the sliding tougue piece g
into its closing position Figure 1, the bead or collar working over the stein e, c,
compresses the spring limbe of the said stem and when the sliding tongue piece
has reached its closing position oue side of the lower edge of the said bead or
collarsnaps into the groove i in the limb e of the spring snap fastening and retains
the said tongue piece securely in its place as illustrated in Figure 1. By pressure
upon the bead or collar it is disengaged from the spring soap fastening i, e and
the sliding tongue piece 9 may be withdrawn to open the bow as illustrated in
Figure 2. Between the top of the stem c and the bow b is a shoulder k which
acts as a stop to limit the advance of the sliding tongue piece to close the bow.
The bead or collar of the swivel may either be made in halves and soldered
together edge to edge or made in one piece, the top and bottom of the bead having
axial holes to permit it to work upon the stem and spring snap fastening o, e; and
the bead or collar instead of having a spherical figure may have a cylindrical or
other figure; or the bead or collar may be made in one piece with the sliding
tongue piece as hereinafter described. The combined bow, eye, and spring snap
fasteuing represented in Figure 4 is made preferably from a piece of wire nearly
half round or semi-circular in cross section in the following manner. The piece of
wire is first bent or doubled upon itself for a short distance near one end and
fashioned at the bend into a circular form so as thereby to form the eye d, the stem c
and the limb or spring suap fastening e. While the wire above the stone is iu
the straight or unbent form, the hollow bead or collar fis passed or threaded onto
the said straight stem; the upper half of the wire above the stem e is now bent
into the complete or closed bow b of the swivel. The part g of the bow to form
the sliding tongue piece of the swivel is next cut obliquely at the dotted line from
the complete bow and the separated piece is soldered or otherwise connected to the
bead or collar as represented in Figures 1 and 2 and the swivel, after the
formation of the groove i in the limb e, is complete.
Although I find it convenient to obtain exactness in the sliding tongue piece first
to make the complete bow and afterwards to cut the sliding tongue piece from it
yet the sliding tongne piece may be otherwise made.
Instead of retaining the sliding tongue piece in its place to close the bow by a
spring soap fastening, a coiled spring may be used for that purpose. This modified
swivel is represented closed in Figure 5 and open in Figure 6 and the combined
stem, bow and sliding tongue piece of the same detached in Figure 7. In this case
a tubular box m is made to surround the lower part of the stem c, the bead or
collar carrying the tongue piece 9 sliding over the said hox; n is a coiled spring
in the box m the said spring bearing at top against the interior of the bead or
collar and tongue piece g and at bottom against the closed end of the cylindrical
box m. The box m is fixed to the stem e, e by soldering the bottom end of the
said stem to the interior of the bottom of the box. When the bead or collar fis
depressed to open the swivel, the spring n is compressed as illustrated in Figure 6
and when the bead is released the pressure of the compressed spring n advances
the bead and its sliding tongue piece 9 and retains the latter in its closing
position as illustrated in Figure 5. In this modification the loop d of the swivel is
made separate from the stem and bow and is soldered to the bottom of the spring

page_text: box m, the stem c, bow b and, tongue piece 9 being made from one piece of wire as
described with respect to Figure 4.
In making the bend and sliding tongue piece in one piece I proceed as follows.
I take the sheet metal blank represented in front elevation and section in Figure 8
and make from the part p the bead and from the part q the tongue piece of the
Swivel. To effect this I first cup or give a concave figure to the part p of the
blank and bend the part q at the required angle to the said part pas represented
in section in Figure 9. The cupped part p is next bent at its middle the sides of
the doubled parts being brought parallel or nearly parallel to one anothor as
represented in section in Figure 10 and the parallel parts are then bent or
fashioned into a globular figure and their edges joined by soldering. Figure 11
represents the finished bead. marked p'. The combined head and sliding tongue
piece is thus made from one piece of sheet metal and may be used in place of the
separate bead. and tongue piece hereinbefore described and the soldering of the
-tongue piece to the head thus avoided.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that I claim
as my invention of "Improvements in swivels for chains, cuff links bags, straps
and other articles" :-
First. Opening and closing the bows of swivels by means of a sliding tongue
piece carried by a. bead or collar working over the stem or spring box of the
swivel, whether the sliding tongue piece be retained in its advanced position to
close the bow by a spring snap or other like fastening or by a coiled spring
substantially as hereinbefore described and illustrated in Figures 1, 2, 3, 4, 5 and 6
of the accompanying drawing.
Secondly. Making the combined bow, stem, eye, and spring snap fastening of the
swivel to be used with the sliding tougue piece and bead or collar claimed in the
first claim, from a single piece of wire bent and fashioned as herein before described
and illustrated with respect to Figure 4 of the accompanying drawing.
Thirdly. Making the combined bow and stem of the swivel to be used with the
spring pressed sliding tongue piece and bead or collar, from a single piece of wire
bent and fashioned as hereinbefore described with respect to Figure 7 of the
-accompanying drawing.
Fourthly. Making the bead and sliding tongue piece of the swivel from a blank
of sheet metal by the combination of processes herein before described and illustrated
in Figures 8, 9, 10 and 11 of the accompanying drawing.
