Improvements in Bracelets, Necklaces, Chains, and the like.
I, ERNEST MURRLE of 11 Charterhouse Street, London, Wholesale Jeweller,
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 :-
This invention refers to bracelets applicable also to necklaces, chains and the
like and consists in a method of construction whereby great flexibility can be
obtained with a positive elasticity in length, while nothing but a metal surface is
visible.
This result is obtained by forming a chain composed of two parts connected
together alternately. One of these parts is a hollow boss or bead, with holes on
two opposite sides, through which enter the ends of a hollow link-bar or tube.
The ends of this link are turned over or flanged inside the boss, so that they
cannot be drawn out, but they can be pushed farther in until they meet inside, and
they have thus an amount of play which is more or less, according to the length of
the diameter of the boss from hole to hole.
Through these tubular links is passed a tension spring of coiled wire or india-
rubber, the ends of which are connected so as to form a ring sufficiently tight to
bold the tubular links in contact.
From this arrangement it follows that the chain so formed can be extended
longitudinally by the distance equivalent to the total play of the links in the
bosses, and the internal spring resisting this elongation causes the elasticity
referred to.
These chains can be grouped or connected sideways and formed into bands
suitable for bracelets and like purposes, and can be combined with suitable devices
and ornaments.
I will now describe my invention with reference to the accompanying drawings
in which,
Fig. 1 shows a portion of a bracelet, of suitable design, in the contracted position,
constructed on my improved system.
Fig. 2 shows the bracelet in the expanded position.
Figs. 3, 4, and 5, show other designs suitable for bracelets or the like.
Fig. 6 shows details of the elastic formation composed of bead, tubular link and
spring.
a is the coiled tension spring which runs through each series of tubes and beads
forming the chain which forms the foundation of the bracelet or necklace.
b is a hollow connecting boss or bead pierced on either side, which may be of
spherical or any suitable shape.
care short connecting tubes forming the links between the bosses bb. The ends
of each link inside the bead are opened out so as to prevent the link from leaving
the bead while allowing a certain amount of play between the links.
The chain of combined beads and links, may be used alone as a bracelet or may
be combined with other devices instances of which are shown in Figs. 3, 4, and 5.

tion, and in what manner the same is to be performed I declare that what I
-claim is :
In a bracelet necklace or chain, the construction of hollow beads or bosses with
tubular links having expanded ends in combination with an internal tension spring,
as herein described and set forth.
