IMPROVEMENTS IN BUTTONS WITH PINS
Year: 1880

Barazia at the Office of the Commissioners of Patents on the 4th October
1880.
JEAN ALFRED RUBINO DE BARAZIA, of La Rochelle, in the Republic of France.
"IMPROVEMENTS IN BUTTONS WITH PINS."
The object of this Invention is the construction of a button fastening precluding
the possibility of accidental loss.
The four Figures of the accompanying Drawing are all on an enlarged scale, and
the same letters thereon serve to indicate the same parts in all the said Figures.
Independently of the head A and of the base B (the forms and sizes of which may
be varied as may be required by use or according to the taste of the wearer), this
fastening consists in two cylinders C and F, the latter entering the former in a
peculiar manner, and which constitute together the stem of A and B.
Fig. 1 represents the external cylinder C in section and attached to the base B,
inside and at the bottom of which is placed a rubber disc E, which acts as a
spring, and which may be replaced by a metallic spring. D is a meta llic pin passed
diametrically and horizontally through the cylinder C in which it is fixed at both
ends.
The inner cylinder F, shewn laterally as in Fig. 2, is also hollow and united
by its upper end to the head A; in its lower edge are cut two slots G, g, of a
peculiar shape, the longer parts of which are vertical, from which they are extended
horizontally at right angles, and which are finally terminated by short notches g
which descend vertically.
Fig. 4 shews the cylinder F developed or laid out flat in order to shew the nature
and the position of its two slots G, g.

page_text: In order to close the button (see Fig. 3), the internal cylinder F is inserted in
the external cylinder C, at the same time turning and pressing lightly thereon
until the two slots G of the cylinder F meet the cross pin Ď of the cylinder C; then
this cylinder F is pushed down to the botton C on the spring E, and then turned
horizontally until arrested by the contact of the cross pin D; then by releasing the
cylinder Fit is pushed up automatically by the spring E, the cross pin D having
entered the short slot g, as shewn in Fig. 2.
In order to separate or open the button, pressure is applied on the head A so as
to liberate the cross pin D from the slots g, and the above mentioned evolutions
are performed inversely.
This kind of fastening may be regarded as a lock of which the cross pin D forms
the bolt.

"IMPROVEMENTS IN BUTTONS WITH PINS."
The object of this Invention is the construction of a button fastening precluding

The four Figures of the accompanying Drawing are all on an enlarged scale, and
the same letters thereon serve to indicate the same parts in all the said Figures.
Independently of the head A and of the base B (the forms and sizes of which may
be varied as may be required by use or according to the taste of the wearer); this
fastening consists in two cylinders C and F, the latter entering [the former in a
peculiar manner, and which constitute together the stem of A and B.
Fig. 1 represents the external cylinder C in section and attached to the base B,
inside and at the bottom of which is placed a rubber disc E, which acts as a spring,
and which may be replaced by a metallic spring. D is a metallic pin passed
diametrically and horizontally through the cylinder C in which it is fixed at both
ends.
The inner cylinder F, shown laterally as in Fig. 2, is also hollow and united by
its upper end.to the head A; in its lower edge are cut two slots G of a peculiar
shape, the longer parts of which are vertical, from which they are extended
borizontally at right angles, and which are finally terminated by short notches g
which descend vertically.
Fig. 4 shews the cylinder F developed or laid out flat in order to show the nature
and the position of its two slots G, g.
In order to close the button (see Fig. 3), the internal cylinder F is inserted in
the external cylinder C, at the same time turning and pressing lightly thereon
until the two slots G of the cylinder F meet the cross pin D of the cylinder C; then
this cylinder F is pushed down to the bottom of Ĉ on the spring E, and then
turned horizontally until arrested by the contact of the cross pin D; then by
releasing the cylinder F it is pushed up automatically by the spring E, the cross
pin D having entered the short slot g, as shewn in Fig. 2.
In order to separate or open the button, pressure is applied on the head A so as
to liberate the cross pin D from the slots g, and then the above mentioned
evolutions are performed inversely.
This kind of fastening may be regarded as a lock of which the cross pin D forms
the bolt.
Having now described the nature of the said Invention, and illustrated the
same in such manner that others will be enabled to carry my improvements into
effect, I claim,—
First. A button made in two parts, one of which consists of the head and of a
cylindrical hollow stem having on its lower edge a notch of the form of an
inverted and the other part of which consists of the base and of a stem which
is also hollow and cylindrical, and which surrounds the notched stem, and which
by means of a horizontal and diametrical pin is engaged with the short notch or
depression at the bottom of the above mentioned notch; the two parts of the
button are maintained in this relative position by the elastic force of a rubber
washer or of a metallic spring, all as above described and shewn in the Drawing.

page_text: Second. The use of this locking system for every other object to which it is
applicable.
In witness whereof, I, the said Jean Alfred Rubino de Barazia, have hereunto
set my hand and seal, this Eighteenth day of February, in the year of
our Lord One thousand eight hundred and eighty-one.
Witnesses,
R. H. BRANDON.
