Improvements in Bracelets.
I, CARL BACHEм of Pforzheim in the Grand-Duchy of Baden, German
Empire, Jeweller do hereby declare the nature of this invention to be as
follows:-
The object of my invention is to provide bracelets with a solid shutting mechanism
of most simple construction and having no parts jutting out from the surface of the
bracelet.
For this purpose I divide the annular bracelet into two parts and connecting the
ends on the one side of the semi-circular parts by a joint allowing the two
branches to be laterally moved one against the other, provide the other ends
respectively with a slit and with a projection lying within the body of the bracelet
when closed.
In order to make my invention more clear, I refer to the accompanying drawings,
in which similar letters denote similar parts throughout the different views.
Fig. 1 shows the bracelet completely opened.
Fig. 2 shows the bracelet nearly shut.
Fig. 3 shows the bracelet completely shut and partly in elevation.
Figs. 4 to 6 show a modification of the shutting device, in the same position
respectively as shown by Figs. 1 to 3.
The ends of the bracelet opposite the joint j are sloped and covered by oblique
plates p p¹, one of which p is slitted and the other pl provided with a nose or
hook h. When the opened bracelet is to be shut the branches 6 b¹ are moved
against each other and the outer curved rim of nose his pushed against the under
part of plate p. Now the branches b¹ will act as springs in such a manner that
they withdraw a little, thus allowing hook h to slide upon the oblique plate p and
then to enter the slits of that plate. The bracelet is thus firmly shut, the noose
or hook being held within the slits of plate p by the elastic power of the bracelet
itself.
In order to allow opening of the bracelet without drawing the branches b b¹
to the left and to the right respectively, the inner rim of the hook h is also
curved, and the opening of the bracelet may be effected now by moving the two
branches in contrary sense to the direction in which the bracelet was shut
before. The outer curved rim of the hook will slide then again upon the oblique
plate p till leaving it and the branches 6 b' may be turned then back to the position
shown in Fig. 1.
The inner curved rim of the hook h is intended to prevent the bracelet from
break in case of mistakingly trying to open the bracelet in wrong manner.
A modification represented by Figs 4 to 6 has the same purpose for its object
and prevents the bracelet from break in still a better way by the following con-
struction. The hook h formed as shown by Figs. 4 to 6 is near its base provided
with a slits adapted to catch behind the oblique plate p when the hook his pressed.
into the slits of plate p in the manner explained above. As clearly to be seen in
Fig. 6 it is rendered impossible now to open the bracelet in wrong way, the hook h
holding the two branches 6 b' firmly connected in case the wearer of the bracelet
should try to open it wrongly. The bracelet with this modification is opened in
exactly the same manner as described above. Both constructions of the shutting
mechanism of the bracelet are not in the least liable to get out of order as there

together by their own elasticity.

COMPLETE SPECIFICATION.
Improvements in Bracelets.
I, CARL BACHEM of Pforzheim, in the Grand-Duchy of Baden, German
Empire, 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 :-
The object of my invention is to provide bracelets with a solid shutting mechanism
of most simple construction and having no parts jutting out from the surface of the
bracelet.
For this purpose I divide the annular bracelet into two parts and connecting
the ends on the one side of the semi-circular parts by a joint allowing the two
branches to be laterally moved one against the other, provide the other ends
respectively with a slit and with a projection lying within the body of the bracelet
when closed.
In order to make my invention more clear, I refer to the drawings, sent in with
Provisional Specification, in which similar parts are denoted by similar letters
throughout the several views, and in which :-
Fig. 1 shows the bracelet completely opened;
Fig. 2 shows the bracelet nearly shut;
Fig. 3 shows the bracelet completely shut and partly in elevation ;
Figs. 4-6 show a modification of the shutting device, in the same position
respectively as shown by Figs. 1 to 3.
The ends of the bracelet opposite the joint are sloped and covered by oblique
plates p p¹, one of which p, is slitted and the other p¹ provided with a' nose or
hook h. When the opened bracelet is to be shut the branches 6 b₁ are moved
against each other and the outer curved rim of nose h is pushed against the under
part of plate p. Now the branches 6 6 will act as springs in such a manner, that
they withdraw a little, thus allowing hook to slide upon the oblique plate p and
then to enter the slit s of that plate. The bracelet is thus firmly shut, the nose
or hook being held within the slit s of plate p by the elastic power of the bracelet
itself.

.
Tu order to allow opening of the bracelet without drawing the branches 6 6¹ to
the left and to the right respectively, the inner rim' of the hook is also curved,
and the opening of the bracelet may be effected now by moving the two
branches 66 in contrary sense to the direction in which the bracelet was shut
before.
The outer curved rim of the hook h will slide then again upon the oblique
plate p till leaving it and the branches 66' may be turned then back to the position
shown in Fig. 1.
The inner curved rim of the hook his intended to prevent the bracelet from
break, in case of mistakingly trying to open the bracelet in wrong manner.
A modification represented by Figs. 4 to 6 has the same purpose for its object
and prevents the bracelet from break in still a better' way by the following con-
struction The hook formed as shown by Figs. 4 to 6 is near its base provided
with a slits adapted to 'catch behind the oblique plate' p when the hook his
pressed into the slit s of plate p'in the manner explained above. As clearly to be
seen in Fig. 6 it is rendered impossible now, to open the bracelet in wrong way,
the hook holding the two branches firmly connected in case the wearer of

page_text: the bracelet should try to open it wrongly. The bracelet with this modification
is opened in exactly the same manner as described above. Both constructions of
the shutting mechanism of the bracelet are not in the least liable to get out of
order as there are no parts to be moved except the two semicircular branches,
which are held together by their own elasticity.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what
I claim is :-
In a bracelet: The combination of the two branches of the bracelet, the ends
opposite the hinge being sloping and covered by oblique plates, one of which is
provided with a nose or equivalent fastening device and the other with a slit, the
same being adapted to enter the slit, substantially as set forth.
Dated this 23rd day of May 1891.
