Improvements in Brooches.
I, JEAN BERTHOND, of l'Isle sur Venage, Switzerland, Inventor, do hereby
declare the nature of this invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:
My invention refers to brooches for personal wear, and the object is to remedy the
defects in brooches as hitherto made.
Amongst the causes which produce the rapid deterioration of brooches, the most
common is the necessity of forcing the brooch pin out of its natural position, in order
to insert it in the metallic catch which keeps it in position so as to fasten the
brooch.
Inasmuch as this movement causes the pin to undergo a great lateral pressure,
the pin gradually curves and gets out of shape (unless it be made of tempered steel)
and so at last the brooch becomes useless. But if on the other hand the pin is
strong, this pressure bears entirely upon its support, which yields little by little
to the pressure and the support gives way. Generally, though not always, it is
the hinge which suffers because it is the most delicate part.
The object of this invention is to obviate the inconvenience I have hereinbefore
mentioned. In order to attain this object, I add to the movement which the
pin is accustomed to make, a movement parallel to the surface of the brooch.
The combination of these two movements allows the pin to accomplish without
resistance, all the movements required by the fastening of the brooch to various
garments.
1 give the pin this additional movement by making its support turn upon a
pivot which is soldered or otherwise secured to the brooch and consequently
immovable.
In the accompanying drawings I have illustrated the application of my invention,
like letters of reference indicating corresponding parts throughout the figures.
Figure 1 is a perspective view of the back of a brooch with my invention applied
thereto.
Figure 2 shows the pin of a brooch and its hinged support provided with
a pivot.
Figure 3 shows another mode of applying my invention, and
Figures 4 and 5 show various plates of metal for fastening the pivot to the body of
the brooch.
A is the body of the brooch, a is the pin which is binged at b, said hinge allowing
the pin to move in a plane vertical to the surface of the brooch, e is the support
which is provided with a pivot d to allow the pin to move in a plane parallel to the
surface.
The pivot d may be applied in two ways:
It may be riveted or otherwise fixed upon the back face of the brooch if the said
face is of sufficient strength and its shape allows of this arrangement, or if this cannot
be employed, the pivot d may be riveted or otherwise secured to a small independent
plate of metal, said plate being afterwards fixed upon the brooch. Figure 3 shows
this last-mentioned mode, e being the small plate of metal, d the pivot which is firmly
riveted thereto, the end of the said pivot being formed into a button by the act of
riveting. This riveting allows sufficient play to the pin to allow it if required, to
describe a complete circle round the pivot.
This independent plate of metal with the pivot secured thereto is likewise fixed to
the brooch which may be done by cement, glue, rivets, screws or otherwise, according
to the material of which the brooch is made.

page_text: This plate must be made of some material of sufficient resistance to stand the
strain to which it is subjected. Its shape may be varied to suit various forms of
brooches, and if desired, it may be made as shown in Figure 5, raised in the centre to
which the pivot is riveted or otherwise secured and fastened to the brooch by pins,
screws or other means.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to bo performed, I declare that what I
claim is:
In a brooch having an ordinary brooch pin hinged in the usual way, the
combination of a pivot attached to hinge aforesaid, in the manner and for the
purposes set forth and illustrated in the drawings annexed.
