A New or Improved Strengthening or Reinforcing Ring for Weak or
Worn Finger-rings and the like.
I, JOHANN JOSEPH BOHR, of Saarlouis, Rhine Province, Prussia, Watch-maker.
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 relates to a new or improved strengthening ring by the employ-
ment of which weak or thin finger-rings or the like. which have been worn down
by lengthy use or otherwise reduced may be strengthened or reinforced.
In the accompanying drawing Figure 1 represents a transverse section of such a
strengthening ring; Figures 2, 3 and 4 illustrate various methods of applying the
invention.
The strengthening ring a has the outer form of an ordinary ring. and has in
its internal surface a groove b, the width of which corresponds to that of the
worn or reduced ring e.
In order to strengthen the worn or reduced ring e, it is only necessary to cut it
across and then introduce it in a suitable manner into the groove 6 of the
strengthening ring a (Figure 2). The cross section of the ring c in conjunction
with the ring is thus considerably reinforced or strengthened, and the further
advantage is attained, that the inscription, situated on the inside of the ring c
remains visible. In order to prevent the possibility of the ring e falling out of the
strengthening ring a, it may be soldered together again at the point where it was
cut, and also firmly soldered along its longitudinal edges into the groove b.
The groove situated in the ring a can be made in a variety of ways, for example,
as shown in Figures 1 and 2, by soldering in place suitably shaped rings dd, or
as shewn in Figure 3 by pressing over the internal edges dd. In the latter
case the advantage is simultaneously obtained, that the ring e requiring to be
strengthened, can be wider than the groove b formed in this manner, as the edges
of the worn ring may extend into the space formed by the bent-over parts d',
the dedication or inscription in the ring still remaining visible. If on the other
hand the bent-over edges are so lengthened or extended that, as shown in Figure 4,
they form an inside plate, the inscription in the ring will no longer be visible,
and the finger ring c requiring to be strengthened will be enveloped on all sides by
the strengthening ring a.
In order to insert the worn finger ring into the interior of the strengthening
ring, in the arrangement shown in Figures 3 and 4, it is necessary to cut open
the lanning-over pieces d¹ d'or the inner plate at some point in such a way
that the previously cut finger ring can be introduced at this point into the inside
of the strengthening ring. By soldering both parts, the strengthening ring with
the finger ring, a secure union of both can also be effected in this instance.

page_text: 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-
:-
A strengthening or reinforcing ring for weak or worn finger rings, and the
like, having a groove, recess, or chamber to receive the worn or reduced finger or
other ring, substantially as described with reference to the drawings.
