Fig. 1 of the drawing illustrates a cord-bracelet
of usual construction comprising a pair of looped
cords II and I2 having their ends gripped in
fasteners or end-clasps I3 forming the subject
matter of the present invention. The clasps I3
are connected together by a separable link I5
of usual construction which embraces bails I6
formed on the clasps. At the outer closed end
of the loops of the cords I I and I2 are end-pieces
or connecters il adapted to be attached to the
balls of a Wrist-watch or similar parts of other
articles of jewelry or the like. Metal loops I8 of
usual construction are also provided for encir
cling the cords II and I2 to hold them in parallel
relationship.
As more clearly shown in the detailed views of
the drawing each clasp I3 comprises a box-like
body-member or holder 20 having a top wall 2l
of a contour corresponding with the contour- of
the end of the bracelet and side Walls 22 and 23;
it being understood that Figs. 2 to 10, inclusive,
illustrate the clasp in inverted position or bottom
side up. The bottom edges of the side walls 22
and 23 are bent inwardly to provide flanges 24 60

extending from one end of the body-member 2|!
to a point adjacent the opposite end. At one
end of the member 20 the walls'22 and 23 are
narrowed with the top wall 2| curved down
wardly in conformity therewith. Adjacent this
tapered end the top wall 2| is apertured at 25
to form the bail I6, previously referred` to. The
otal connection between the elements causes the
gripper-element 21 to be bodily moved longitu
dinally to a position where the ends of the teeth
30 underlie the top‘portion 2| of the body-mem
ber 20 to secure the bracelet end to the fastener.

The gripper-element 21 is in the
15 -form of a relatively narrow plate 28 having _pin
tles 29 projecting laterally at one end and pref
erably formed integrally with the plate. At its
opposite end the gripper-element 21 is widened
to form a crossbar having depending sharp
20 pointed teeth 30 for engaging the cord or other
type of bracelet and a tapered or wedge-shaped
spacing tooth 3| for engagement between thecords to force them apart. The crossbar at the
toothed or gripping end of the element 21 forms
v25
shoulders 32 projecting outwardly from the sides
of the plate 28 in opposite directions for engage
ment with the flanges 24 on the body-member 20.
Adjacent the end of the gripper-element 21 from
which the pintles 29 project the plate 28 is de
30 formed to provide a. transverse recess or groove
33 for a purpose later to be described.
'.
The gripper-element 21 is adapted to be drawn
longitudinally into the body-member 20 by an
actuating member 34 shown in detail in Fig. 10.
35 The actuating member 34 is in the form of a
lever having side ñanges 35 extending from one
end to a point adjacent its opposite end and at
this latter end the lever is slightly curved to form
a ñnger-piece 36. Adjacent the end of the actu
40 ating lever 34 opposite from the finger-piece 36
the side flanges 35 are provided with bearing
,apertures 31 for receiving the pintles 29 on the
gripper-element 21 to provide a pivotal connec
tion between the two elements. The opposite side
45 flanges 35 are so spaced as to straddle the plate
28 of the gripper-element 21 so that the two ele
ments may be folded one over the other. The
outward faces of the ilanges 35 are also adapted to
llt closely between the inwardly-directed flanges
50 24 of the body-member 20 and are provided with
bearing apertures 38 intermediate their ends
adapted to be alined with the bearing apertures
26 in the side walls 22 and 23 of the body-mem
ber 20.
'I'he actuating lever 34 is pivotally mounted on
55
the body-member 20 by a pin 39 extending
through the alined bearing apertures 26 in the
side walls of the body-member 20 and the aper
tures 38 in the flanges 35 of the actuating mem
60 ber 34, the ends ofl the pin 39 being riveted or
headed over to retain the pin in position. The
actuating lever 34 when thus mounted is adapted
for rotation from an open position, shown in
Fig. 4, to a closed position as shown in Fig. 3,

4D being provided on the outer faces of the side
iianges 35 of the lever for engagement with the
inwardly-directed ilanges 24 on the body-mem
ber 2U to latch the lever in its closed position.
70 During this rotation of the actuating member
34 the pivotal connection between the pintles 29
and bearing apertures 31 of the articulated actu
ating and gripping elements is moved from one
side to the other of the pivotal axis about which
the actuator rotates. This movement of the piv
will thus be positioned outwardly beyond the end
of the body-member 29 so that its laterally 15
projecting shoulders 32 will clear the outer ends
of the inwardly-directed flanges 24. The grip
per-element 21 is next rotated on its pintles 29
to a rearward position overlying the actuating
element 34 with the transverse recess or groove 20
3_3 providing a clearance for the pin 39 as shown
in Fig. 4. 'I‘he ends of the bracelet cord may
then be laid in the body-member 20 between the
sidewalls 22 and 23. When the ends of the
cord are properly positioned in the body-mem
ber 20 the gripper-el^ment 21 is turned back to
the position shown in Fig. 6 and the ringer
pressed thereagainst to force the teeth 30 through
the individual cords with the spacing tooth 3|
entered between the cords || and | 2 to spread
them apart. The lever-extension- or linger-piece
36 is then grasped to rotate the actuating mem
ber 34 about the pivot-pin 39 as shown in Fig. '1
until the detents 40 on its side flanges 35 engage
under the inwardly-directed flanges 24 >on the
body-member 20 Ito latch the clasp in a closed
position. During this rotation of the actuating
member 34 the pivotal connection formed by the
pintles 29 engaging the bearing apertures `31
at the end of the gripper-element 21 is displaced 40
from one side to the other of the pivotal axis or `
pin 39 about which the actuating lever rotates.
This relative longitudinal movement of the piv
otal connection between the articulated mem
bers causes the toothed end of the gripper-ele
ment 21 positioned exterlorly of the body-mem
ber 20 to be drawn thereinto. As the gripper
element 21 is pressed firmly against the cords | |
and |2 its shoulders 32 are carried into engage
ment with the inturned flanges 24 on the body
member 20 to lock it in position with the ends 50
of the teeth 30 and 3| extending through and
between the cords held in close cooperative rela
tionship with the top wall 2| of the body-member
to positively grip and secure the end of the cords
to the clasp. When the parts of the clasp are in
their closed gripping relationship the actuating
member 34 overlies the gripper-element 21 to
provide a'smooth under surface with the side
flanges 35 positioned between the flanges 24 and
straddling the plate-portion 28 of the gripper
element.

From the foregoing description it will be ob
served that the invention provides a novel con-_
struction and arrangement of elements in a fas
tener or end-clasp for positively holding the ends
of a bracelet. It will be further apparent that
the present fastener acts to grip the ends of the
cord exteriorly of the holding or body-member
so that the longitudinal movement of the gripper 70
element will draw them into the holder to insure
a positive grip and secure anchorage therefor.
Due to this novel and improved method of op
eration of the device it is not required to push
the ends of the cord clear into the clasp before 75

closing its parts to grip the ends and, conse
quently, the ends are less apt to become frayed.
Moreover, since the ends of the cord are drawn
into the clasp by the gripper-means instead of
being pushed outwardly as in previously used de

portions or lugs only are necessary to pivotally
mount the actuating member and provide a guide
way for engaging the shoulders 32 on the gripper
