SWIVEL CONNECTER
William A. H. Wells, Edgewood, It. I.
Application Mayl22, 1937, Serial No‘. 144,193
6 Claims.
This invention relates to a connecting device,
particularly of the character used on the end of a
watch chain or the like for connecting the chain
to the ring in the stem of-a watch, and is some
5 times referred to as a swivel; and has for one
of its objects the construction of such a device
which will e?ectively prevent the removal of the
spring actuated tongue when the parts are in
,
1
is-
'20
assembled position.
'
,
,
Another object of the invention is the provision
of means to prevent the twisting of the tongue
about a longitudinal axis through the tongue and
thus prevent the wings which extend beneath the
end wall of the body of the connecter from being
so disposed that they may be removed through
the opening in the end wall of the connecter.
Another object of the invention is ‘to form a
guide for the directing of the spring which urges
the tongue toward one extreme of its position in
place.
‘
-
Another advantageous feature of the invention
which is incidental to the objects thereof is to
(Cl. 24—240)
suit I have provided a pair of ?ngers on the end
of the shank of the hook which extends into the
body to effectively prevent the twisting of the
tongue and removal thereof, and also these ?ngers
serve the advantageous purpose of providing a 5
guide for the insertion of the spring in place while
also preventing ?ne shot which is used in the tub
ing of these devices from entering the connecter
to clog up its operation; and the following is a 3
more detailed description of the present embodi- m
mentof this invention, illustrating the'preferred
means by which these advantageous results may
be accomplished:
With reference to the drawing, [0 designates
the hollow body 'of the device which is provided 15
with an end wall ll having an opening l2 therein
of the shape shown in Fig. 7. A stud I 3 extends
from the body to receive a swivel collar l4 which
may rotate thereabout and is held in position by
the riveting over or heading l5 of this stud I 3. 20v
A ring I6 is rockably mounted in a bearing I‘! in
the swivel collar I4, it being bent into abutting
prevent shot which may be used for the tubing . relation with the collar as at l8 at the diametri
of the connecter from getting into the hollow cally opposite portion of this collar.
25 body of the connecter.
'
'
.
With these and. other objects in view, the inven
tion consists of certain novel features of construc
tion, as will be more fully described, and'partic
30
ularly pointed out‘in the appended claims.
In the accompanying‘ drawing:
'
Fig. 1 is an elevation of the connecter ?nished;
Fig. 2 is a central sectional view thereof with
the tongue in closed position;
'
. Fig. 3 is a view similar to Fig. 2 of the tongue
35 in open position;
.
‘
.
Fig. 4 is a sectional view on line 4-4 of Fig. 2;
Fig. 5 is a sectional view on line 5P5 of Fig. 3
showing only the tongue and the fingers and their
relationship on the end of the hook;
Fig. 6 is a sectional view of the hollow body of
the connecter;
,
.
Fig. 7 is an end view of the body of the con
necter;
-
Fig. 8 is a top plan view of the shank and tongue
45 in one stage of their formation;
Fig. 9 is a central sectional view of the struc
ture shown in Fig. 8.
In the use of connecting ‘devices of the char
acter here shown, often referred to as swivels, it
frequently occurs that thetongue which is spring
pressed to closed position becomes twisted permit
ting removal of the tongue from the opening in
the hollow body, and it is known that if the swivel
be struck in a certain manner the tongue will
55
often be displaced; and in order to avoid this re
. The shank and tongue are ?rst fashioned in a
single piece 20, as shown in Figs. 8 and 9. By a
suitable striking or pressing operation wings 2|
are formed at one end ‘of the bar 20 by providing
a suitable cup 22 therein to spread the stock in
the desired manner. The other end 23 of the bar
20 is formed bifurcated by providing the slot 24
and I bend the ?ngers 25 at either side of the slot
laterally or at right angles to the bar, as shown
in Fig. 9, prior to the bending of the bar 20 into
generally the shape of a loop, as illustrated in
Figs. 1 and'2. -
'
After the bar is bent into the loop shape indi
cated and forming the opening 26 the wings 2|
are inserted through the opening l2 by disposing
them longitudinally of this opening and then the we
loop-shaped bar 20' is rocked through 90° to dis
pose the wings beneath the end walls ll of the
hollow body and the other end of the bar, com
prising the laterally extending ?ngers 25, are
inserted through the opening, and this last in 5
serted portion of the bar is soldered in position
as at 21, shown in Figs. 2 and 3.
.
The spring 28, shown in Figs. 2 and 3, is then
positioned in the slot 24 between the ?ngers 25 by
inserting the bent portion 29 thereof into the
position shown having the one arm 30 in a recess
3| between the ?ngers with its end adjacent the
abutment 32 formed by this recess, while the other
end or arm 33 is disposed within the recess 34

with its end adjacent the abutment 35 formed by
tion extending toward and in su?iciently close
this recess.
proximity to said wings so as to prevent twist
The tongue portion 36 is then formed distinct
from the hook portion 31 and its shank 38 by
through an angle of 90°, and a spring having a
severing along the line 39 on an angle, as illus
trated in Figs. 1, 2 and 3, so that the end 40
of the tongue 36 will abut the beveled end 4|
of the hook so as to come to a complete stop
and alignment, which is desired. Rocking of the
tongue takes place by reason of the iconyex arou
ate surface :42 of the wing riding within the
' concave surface 43 of the body portion of the
device and is guided by the edges of the opening
15 I2 in the end wall ll of the body.
