R. L, a corporation of Rhode Island
Application January 2, 1936, Serial No. 57,238
13 Claims. (Cl. 40-140)
This invention relates to buckles, clasps and
like devices for connecting the ends of wrist
watch straps, bands, bracelets and similar arti
cles and more particularly to devices in which
Cl
interchangeable initial letters or other ornamen
tal insignia. may be mounted.
One object of the invention is to provide a
fastening device for straps, bands or bracelets
having a novel construction and arrangement of
elements for mounting and displaying inter
changeable initial letters or other character
elements.
Another object of the invention is to provide
an extensible clasp of the type indicated com
prising a plurality of hinged members adapted
to be folded into overlying relationship in a cover
member with means in the cover for mounting
the character elements.
Another object of the invention is to provide a
2-0‘ device of the type indicated including a movable
plate which overlies the character elements to
hold them in place and a slidable extension mem
2
ber for adjusting the length of the clasp which
latter member overlies the plate and holds it in
engagement with the character elements.
Another object of the invention is to provide
an extensible clasp of the type indicated having
with its parts folded into overlying relationship
and showing the ratchet-means for latching the
extension member in adjusted position;
Fig. 5 is an enlarged transverse sectional View
taken on line 5—5 of Fig. 4 showing the offset
marginal ?ange and. cooperating plate for hold
ing the character elements in the cover member;
Fig. 6 is a perspective view of the cover member
of the clasp showing the holding plate raised to
its inoperative position to permit the interchange
able character elements to be mounted in the
opening;
Fig. '7 is a view similar to Fig. 6 showing the
plate folded into closed position and the exten
sion member in position to be slid into the cover 15
member; and
Fig. 8 is a perspective view of a modi?ed form
of character element adapted to be set in the
opening in the clasp.
The present invention relates generally to an _
extensible clasp or buckle including a cover mem
ber in which interchangeable character elements
are mounted to be exposed to View through a
suitable opening formed therein. Preferably, the
cover member has an o-ifset marginal ?ange
around the opening forming a recess in which
the character elements are set and the latter
a releasable detent on the retaining plate which
have extended ends which overlie the ?ange. A
cooperates with the adjustable extension. member
30 to limit the outward sliding movement of the
plate overlies the character elements and a re
movable extension member slides in the cover
latter.
I
Still another object of the invention is to pro
vide a clasping device of the type indicated hav
ing an attractive and ornamental appearance, a
simple and compact structure, and one which is
adapted for use over long periods of time with
out repair or replacement of its parts.
Further objects of the invention are set forth
in the following speci?cation which describes a
40 preferred form of construction of the device, by
way of example, as illustrated by the accompany
ing drawing. In the drawing:
Fig. l is a perspective view showing the oppo
site ends of a. two-part bracelet connected to
member and bears against the plate to maintain
the character elements properly positioned in the
recess. The clasp is preferably of the type in
which a plurality of sections are hingedly con
nected to adapt them to be unfolded to lengthen 35
the bracelet and to be folded’ into overlying rela
tionship when on the wrist, but the clasp itself
may take other forms. In the present embodi
ment of the invention the clasp isjprovided with
a slidable extension member and ratchet or simi
lar latching means for holding it in adjusted po
sition.
A releasable detent means is also pro
mounted in the cover member and exposed to view
through an opening therein;
Fig. 3 is a plan view of the clasp illustrated with
vided on the plate which cooperates with the slid
able extension member to limit-its outward move
ment with respect to the cover member.

Referring to the drawing, one form of clasp 2
is herein illustrated for connecting the opposite
sections 3 and 4 of a two-part bracelet, but it
will be understood that other forms of clasps
or buckles may incorporate the novel features of
the present invention. The clasp 2 as illustrated
its sections in extended relationship and showing
the cooperating parts for retaining the character
namely: a base member ‘I, an intermediate hinged
gether by the present improved clasping device;
Fig. 2 is a longitudinal sectionalview illustrat
ing the clasp with its pivoted sections in extended
relationship and showing the character elements
elements in position in the cover member;
Fig. 4 is a plan view of the clasp illustrated
comprises three pivotally connected sections,
connecting member 8 and a top member or cover
9. These several members may be constructed as
_2,108,892
stampings struck up from thin sheet-metal stock
and curved slightly to conform to the contour of
the wearer’s wrist. The base member ‘I may be
constructed in the form of a relatively ?at plate
I5 having side ?anges I I folded upwardly there
from. The opposite ends of the plate portion Ill
extend beyond the side» ?anges I I and are curled
around tov form hinge loops I2 and I3 for con
its lateral edge portions from which the ?anges 3|
depend.
The eifect of this is to provide a raised
panel on the top of the cover 9 and a ?at recess
43 on the under side of its plate portion 30 for
a purpose as later explained. The character
elements 4|] may be in the form of initial letters
of any suitable design, preferably of a thickness
equal to the depth of the recess formed by the
nection respectively with the end link of one of offset ?ange 44, and provided with extended end
the bracelet sections 3 and at the other end with 'bars 45 which engage the'?ange 44 on opposite 10
the intermediate connecting member 8 of the sides of the opening 4|. The character elements
are thus exposed to View in the opening 4| , being
clasp. The side ?anges II have detent projec
tions I4 at their sides which cooperate with the held in their proper spaced relationship by the
cover member 9 when the parts of the clasp are bars 45 the ends of which abut. Any desired
15 folded into closed or clasped relationship in a combination of initial letters may be set in the 15
manner as later more fully explained.

portion I9 having side ?anges 20 folded down
stituted. In this latter modi?cation the charac
ter element is in the form of a plate 41 of suitable 20
wardly therefrom. The ?anges 20 have exten
sions at one end pierced with holes to receive a size‘and shape to ?t into the recess formed by the
hinge-pin 2| extending therebetween and passing
offset ?ange 44 and having ornamental insignia
through the hinge loop I3 .on the base member
'| to pivotally connect the two members. At its
opposite end the member 8 is bifurcated to pro
or other embellishment 48 embossed, engraved or
otherwise delineated on its surface.
vide spaced tabs which are curled over to form
in the recess 43 to cause it to overlie the char
hinge loops 23. The main portion of the mem~
ber 8 is cut away centrally throughout substan
tially its full length to provide a rectangular
opening 25 and the edges of the opening are
in engagement with the marginal ?ange 44.
Preferably the plate 49 is pivotally mounted on
the hinge-pin 33 in the opening between the 30
formed with ratchet-teeth 26 for a purpose as
later explained.
The toprelement or cover 9 is constituted by a
relatively ?at plate portion 30 having side ?anges
3| bent downwardly and then inwardly to form
opposite channels or guideways 32.
A hinge-pin
33 extends through holes in the ?anges 3| adja
cent one end thereof and through the spaced
hinge loops 23 on the member 8 to pivotally con
40 nect the latter to the end of the cover member 9.
It will be observed by reference to Figs. 2 and 5
that the sections ‘I and 8 are adapted to be folded
A thin plate 49 of resilient sheet metal is placed 25
acter elements 40 to hold the end bars 45 thereof
spaced bearing loops 23 on the end of the inter
mediate connecting member 8. For this purpose
the end of the plate 49 is reduced in width and
curled over to form a hinge loop 50 surrounding
the pin 33. The width and thickness of the plate 35
49 are substantially equal to the width and depth
of the recess 43 to form a substantially ?at con
tinuous inner face on the cover member 9.

The extension member 35 is constructed from
a strip of sheet-metal cut away to provide a lon 50
An extension member 35, later to be more fully
described, is slidably mounted in the cover mem
ber 9 and joined’ to the end link of the bracelet
section 4 by means of a connecting loop 36. As
thus far described the clasp is similar to those
previously used in the art in that the three sec
tions ‘I, 8 and 9 can be unfolded to extended re
lationship to permit the bracelet to pass over the
'hand of the wearer and then collapsed by fold
gitudinally extending rectangular opening 52.
The metal at the sides of the opening 52 is bent
or folded over to form upwardly extending side
?anges 53 which are folded inwardly on them
selves to provide opposite parallel guiding rails
54. The rails 54 are adapted to closely ?t within
ing the parts into overlying relationship and into
the channels or guideways 32 of the cover mem

gage the wrist. To facilitate the opening out of
ber 9 to hold the extension member 35 bearing
against the pivoted plate 49 while permitting the
the pivoted sections of the clasp the plate por
tion 30 of the cover member 9 is extended beyond
the side ?anges 3| to provide a ?nger-grip 31
under which the ?nger-nail may be inserted.
In accordance with the present invention the
65 cover 9 is adapted to mount interchangeable
character elements which may take the form of
initial letters 49 or any other desired insignia.
To this end the plate portion 39 of the cover 9
is formed with a rectangular opening 4| bounded
70 by a relatively narrow upset ribbed frame 42
shaped to provide an inwardly-directed marginal
?ange 44 offset from the inner face of the plate.
It is to be further noted that at either side of
the framed opening 4| the plate portion 39 of

within the cover member 9. The end portion of
the extension member 35 forms a crossbar 55
for receiving the connecting loop 36 for joining
the clasp to the bracelet section 4. At its inward 65
end the member 35 is provided with a pair of
resilient pawls 56 which project upwardly into
the opening 25 in the intermediate connecting
member 8 when the parts of the clasp are in
folded 01' closed relationship. The pawls 56 are 70
formed with curved ends 51 which project out—
wardly to engage with the teeth 25 on the edges
of the opening 25 in the member 8. The pawls
