Fastening Device for Bracelets and the like.
I, ADOLF MURRLE of Pforzheim in the Empire of Germany, Manufacturer of
Jewellery, do hereby declare the nature of this invention, and in what manner
the same is to be performed, to be particularly described and ascertained in and by
the following statement :-
The object of this invention is to provide a fastening for bracelets, necklaces,
dog collars and the like which prevents such articles from becoming accidentally
detached from the arm or neck of the wearer.
The fastenings for bracelets, necklaces and the like hitherto devised for the
purpose of preventing loss of the same fail to fulfil their purpose, as they do not
afford absolute immunity against such loss.
This improved fastening however does absolutely prevent the accidental
detachment of the bracelet necklace or the like from the person of the wearer.
The accompanying drawings show how the object above indicated is attained by
the new fastening.
In Figs. 1 and 14 is shown in plan and side elevation (partly in section) a treble
hoop bracelet, in which the two halves a and b of the bracelet turning on a hinge c
are pressed against one another by providing one half a with a suitable flexible
wire d, a definite portion whereof (of any suitable length) passes into the hollow or
drilled part b. At one end this wire carries a button or projecting part w, against
which bears a spiral spring surrounding said wire.
The other free end of said spring bears against the front of the part a, or preferably
against the lock plate g of the part which plate is perforated for the passage of the
wire c. Now when the two parts of the bracelet turn on hinge e, the wire d is
withdrawn from part 6 and tension is put upon the spring by the button w, as soon
as the parts are released, the elasticity of the spring causes the bracelet to close up
again.
Figs. 2 and 24 also show an elliptic bracelet which, however, consists of only
two hoops. In this the closing of the parts a and b is effected by two wires d,
and corresponding springs f. Here a central picce e is employed, to which the
wires are attached.
In other respects, this bracelet is constructed substantially in a similar manner
to that above described.
In Figs. 3 and 34 is shown a bracelet consisting of two pieces not hinged
together.
The two parts are connected by two wires d engaging with springs in the same
way as above set forth, so that when the parts a. b. are separated, tension is put
on the springs, the parts being brought together again by the elasticity of the
springs.
For necklaces, dog collars or the like, the springs may be contained in the part e
and the wires attached to the necklace or collar, the piece e being made somewhat
larger for this purpose.
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 what I
claim is :-
(I) In a fastening device for bracelets and the like, the combination of a spring
