CATCH FOR USE IN DETACHABLY SECUR
ING THE ENDS 0F BRACELETS, CHAINS,
AND OTHER ARTICLES TOGETHER
Arthur Micallef, Cranston, R. I.
Application May 9, 1935, Serial No. 20,625
2 Claims.
My invention relates to improvements in spring
catches for use in detachably securing the ends
of bracelets, chains and other articles together.
It is preferably constructed in a form to detach
5 ably secure the ends of flat articles together, such
as a bracelet made out of pierced flat members
hingedly secured together, after said bracelet has
been laid around the wrist.
An object of my invention is to provide a catch
for use in detachably securing the ends of said
articles together, the prong portion of which may
be an integral part of, or be rigidly attached to
1
an adjacent flat article portion and the compart
ment portion of which may be rigidly attached
to an adjacent fiat article portion, preferably rig
idly attached in such a manner that the catch
itself may appear to be a component part of the
adjacent flat members and which is so designed
to be of such small proportions as not to inter
20 fere with the pierced or other designs on the flat
adjacent portions of the bracelet or article.
A further object of my invention is to provide
a spring catch, sure and positive in its action and
constructed of a minimum number of parts.
A further object of my invention is to provide
25
a spring catch which will automatically lock, be
permanently retained in locked position by a
spring and which may be readily and easily de
tached after depression of the slide member
30 thereof.
A further object of my invention is to provide
a catch means which will permit pivoting be
tween the parts thereof in a locked position in
order to readily bend around the wrist.
35
These and such other objects of my invention
as may hereinafter appear will be bestI under
stood from a description of the accompanying
drawing which illustrates an embodiment thereof.
In the drawing, Fig. 1 is a front elevation of
40 my improved spring catch in locked position with
both the prong means and compartment por
tion thereof rigidly attached to the adjacent flat
bracelet portions.
Fig. 2 is a rear elevation of the parts of my
45 invention shown in Fig. 1.
Fig. 3 is a perspective view of the parts of my
invention shown in Fig. 1 with the prongs de
tached from the compartment portion.
_
Fig. 4 is a vertical, longitudinal sectional View
50 taken along the line Ll-ll of Fig. 3 through the
(Cl. 24-230)
adjacent thereto and about to be inserted within
the slots of the compartment portion.
In the drawing, wherein like characters of ref
erence indicate like parts throughout, Ill gener
ally indicates a spring catch constructed in ac- 5_
cordance with my invention, as stated adapted for
use in detachably securing the ends of bracelets,
chains or other preferably flat articles together,
comprising prong means I2 and a compartment
member I4. As stated hitherto, my invention is 1o
particularly adapted for use in. bracelets, having
flat pierced or otherwise ornamented portions
hinged together to make up the bracelet, or other
solid portions immediately adjacent the catch
I0 and as shown in my preferred embodiment l5
includes the rprong means I2, rigidly projecting
from one end I6 of a flat article, and the com
partment member I4 of my invention having the
inner vertical edge 20 thereof integrally attached
to the other end 22 of the bracelet or other Ilat
article, each end I 6 and 22 in the embodiment
shown comprising the flat members I6 and 22
of a bracelet each having respectively, the prong
means I2 and compartment member I4 integrally
attached thereto.
25
In the preferred embodiment of my invention
shown, I provide two flat prong means I2, each
vertically spaced from the other and rigidly pro~
jecting from the end I6 of said fiat article, ñrst
outwardly as rat 24 substantially in the plane 3
thereof and then substantially at right angles
forwardly as at 26 and with the front 28 thereof
terminating in a cam surface 30 inclined rear
wardly from the top to bottom. Each forwardly
projecting portion 26 is also provided with an 35
indentation in a horizontal edge thereof, in my
preferred embodiment the indentation 32 in the
bottom edge thereof. The other cooperating por
tion of my invention rigidly attached to the oppo
site end 22 of said bracelet comprises in. the.v em- 40
bodiment shown an oblong hollow compartment
member I4 having the inner vertical edge 20
thereof rigidly secured by solder or by other
means to said end 22 of said bracelet to integrally
project therefrom, it being obvious that if de- 45
sired the entire ñat portion 22 of the bracelet
and the compartment member It may be stamped
or molded from flat stock and the compartment
member formed by bending the ends and edges
thereof over to form said compartment member 50

tion thereof pressure may be released on the
slide extension 54 permitting the spring means
to raise said slide member 42 to permit the
portions 50 thereof to slide into the indentations 30
32 of said prong means I2. While I have shown
the spring means 56 as being mounted on the'
lower portion of the compartment member I4, it
is obvious that it may be mounted in the upper
portion of the compartment member I4, the ex 35
