3 Claims.
My present invention relates to the jewelry art,
and more particularly ‘to a novel construction of
lock ‘ring.
‘
‘
The principal object of the present invention is
to provide a lock ring for chains, bracelets, neck
laces and‘ similar articles, which is safe and sure
in'its posing and locking action.
Another object of- the presentinvention is to
provide a lock ring ‘which will withstand strain
and
wear.

sheet stock. The base member 211 (Figs.4 and 5)
comprises a flat ring portion 22 open at the cen

in open or closed position, said means including a
clusive may be used. In this form, the base 32,
Fig. 10, is formed with straight parallel side edges
and rounded ends. One end is pierced to form
the opening 33 to which the chain end is perma
nently attached. The other end is also pierced,
as at 34, and a gap 35 provided in the side edge
to permit insertion of the other end of the chain
or the like. A slot 36 is positioned between the
openings 33 and 34 and is curved parallel to the
opening 34. One side wall of the slot is provided 10
at the center with the node 31.
The lock member 38 for this form is identical-J
to the herein above-described lock member 2|, _ _

ber and a ?nger tab on said lock member adapted
to snap by said node when said lock member is
axially moved into open or closed position.

member mounted on said base member over said

member having a central opening aligning with
the gapped opening in said base and having a gap
with a central opening 4| and gap 42. In assem

the lock member 38 is positioned over the extrud
ed portion with the tab 40 extending into the slot
36. The extruded portion is swedged to lock the
parts together, The operation of this form is
similar to the one shown in Figs. 1 to 7.
}
While I have described certain speci?c'embodi
ments of my invention, it is obvious that changes
may be made in the size, shape, and relative ar
rangement of parts without departing from the
spirit and scope of the invention as de?ned in
the appended claims.
