IMPROVEMENTS IN STUDS SOLITAIRES AND SIMILAR ARTICLES
Year: 1884

page_text: I, JEAN NADAL of 94 Southampton Row in the County of Middlesex, Engineer;
do hereby declare the nature of my invention for IMPROVEMENTS IN STUDS
SOLITAIRES AND SIMILAR ARTICLES to be as follows:-
This invention consists in a novel construction of stud, solitaire or similar
article which will admit of the back passing freely through the button hole without
tearing it.
In carrying out my invention I fix on the back of the head of the stud or
solitaire a long flat stem about the size of the button hole. The outer or free end
of the stem is formed of two semicircular or other suitably shaped pieces which are
hinged to the remainder. The hinges are formed on their inner ends with bevel
teeth into which gears a bevel pinion carried on one end of a rod passing through
the stem the other end of the rod being secured to the head of the solitaire which
is arranged to rotate.
By thus rotating the head the semicircular flaps will be opened that is caused to
assume a position at right angles to the stem, or closed that is form a continuation
of the stem in which position the solitaire can be readily inserted in or withdrawn
from the button hole. A suitable stop will be provided so that the head shall not
turn too far.
A similar effect may be obtained by replacing the pinion by a cross bar and
fitting round the rod or wire a helical spring. This cross bar when the flaps are
closed will lie between them but when the head is turned will open the flaps and
lie in a recess formed for it, being held therein by the belical spring.
In this case the closing of the flaps will be caused by withdrawing the stud or
solitaire from the button hole.
It will be evident that other means may be devised for opening and closing the
flaps by the rotation of the head without departing from the nature of my.
invention.

page_text: I JEAN NADAL of 94 Southampton Row in the County of Middlesex, Engineer
do hereby declare the nature of my invention for "IMPROVEMENTS IN STUDS,
SOLITAIRES AND SIMILAR ARTICLES," and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:-
This invention consists in a novel construction of stud, solitaire or similar
article which will admit of the back of the stud passing freely through the button
hole without tearing it.
In carrying out my invention I form the head of the stud in two parts one of
which fits within the other and is capable of rotating therein. To the back portion
of this head I secure a flat hollow stem of any convenient width and depth. To
the outer or free end of this stem are hinged two semi circular or other suitably
shaped pieces or flaps which are arranged to be opened or closed in opposite
directions by the means hereafter to be explained.
Each hinge is formed on its inner side with bevel teeth into which gears a bevel
pinion carried on one end of a rod passing through the stem, the other end of the
rod being secured by soldering or otherwise to the head of the solitaire so that by
rotating the head in one direction or the other the flaps will be opened or closed.
When it is desired to insert the stud in the button hole the stem is held by the
first finger and thumb of one hand, while the head is rotated by the other hand.
By this means the semi circular flaps will be caused to open, that is to say assume
a position in continuation of the stem. The stem is then inserted in the button
hole and the head is rotated in the opposite direction by which means the flaps
will be caused to assume a position at right angles to the stem and the stud will
thereby be secured in position in the button hole.
A suitable stop will be provided so that the head shall not be turned too far, and
a spring or other suitable means are provided for preventing the head from turning
by itself.
A similar effect may be obtained by replacing the pinion by a cross bar and
fitting round the rod or wire a helical spring. This cross bar when the flaps are
closed will be between them but when the head is turned will open the flaps and
lie in a recess formed therein for it, being held in the recess by the helical spring.
In this case the closing of the flaps will be caused by withdrawing the stud or
solitaire from the button hole.
It will be evident that other means may be devised for opening and closing
the flaps by the rotation of the head without departing from the nature of my
invention.
I have shown in the accompanying drawing a solitaire constructed according to
my invention Fig: 1 being a side elevation partly in section and
Fig: 2 an elevation partly in section taken at right angles to Fig: 1.
a a¹ are the two parts of the head, the part a fits and is capable of turning
witliin the part a. b is the hollow stem to the lower end of which are hinged the
flaps c c. The inner sides of the hinges of the flaps are formed with teeth c¹ into
which gears the pinion d mounted on the end of the rod d the upper end of which
is firmly secured to the part a of the head.

page_text: Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed I declare that what
I claim is
1st A stud or solitaire having a head formed in two parts, a flat stem and a back
consisting of two flaps hinged to the stem and arranged to be opened out or closed
by rotating one part of the head as described.
2nd In a stud or solitaire the back of which is formed of hinged flaps the means
substantially as described for opening out or closing said flaps.
