We, LEON PAUL CONARD of 48 Langham Street in the County of Middlesex,
Engineer, CHARLES FERDINAND VEIT of 28 Bartlett's Buildings in the City of
London, Merchant and GEORGE DICKMAN of 41 Cheapside in the City of London,
aforesaid Merchant, do hereby declare the nature of our invention for IMPROVE-
MENTS IN STUDS AND SOLITAIRES to be as follows:―
The object of this invention is to produce a stud or solitaire which when placed
in position in the shirt front or wristband will automatically lock itself therein.
In carrying out our invention we form the head of the stud or solitaire in two
parts one of which, the front for example is capable of sliding in the other or back
part.
The back part is formed with a broad flat shank or stem and to this stem are
hinged in any convenient manner a pair of semicircular flaps which are arranged to
open in opposite directions.
The shank or stem is pierced in two places to receive two small rods which are
binged to the front of the head and also one to each flap in such a manner that by
pressing or pulling on the front of the head the flaps will be either brought
together or opened as required. Whichever action takes place the return motion
will be effected by means of a spring placed in the head between the front and
back parts.
To insert the stud or solitaire in the button hole it will be necessary first to
close the flaps, this we prefer to do by pressing on the front of the head which will
push the two small rods and thereby rotate the flaps on their hinges. When the
stud is in position and the pressure on the head is removed the front of the head
under the influence of the spring will return to its normal position and in doing
so will pull on the small rods and open the flaps or bring them into a position at
right angles to their former position and thereby form a circular back to the stud
or solitaire.
The head of the stud or solitaire may of course be ornamented by chasing of the
insertion of pebbles or gems or in any convenient manner.

COMPLETE SPECIFICATION.
We LEON PAUL CONARD of 48 Langham Street in the County of Middlesex,
Engineer, CHARLES FERDINAND VEIT of 28 Bartlett's. Buildings in the City of
London, Merchant and GEORGE DICKMAN of 41 Cheapside also in the City of
London aforesaid, Merchant do hereby declare the nature of our invention for
IMPROVEMENTS IN STUDS AND SOLITAIRES and in what manner the same is to be
perforined, to be particularly described and ascertained in and by the following
statement :-
This invention relates to that class of studs or solitaires in which the back of
the stud is formed of a flap or flaps hinged to the shank the object of the invention
being to produce a stud or solitaire which when applied to the shirt front, wrist
band, or other part will automatically lock itself therein.
The invention consists in imparting a rocking motion to the hinged flap or flaps
by means of a sliding rod or rods pivotted to the flap or flaps and working in the
stem, the rod or rods being caused to slide in one direction by means of direct
pressure and in the other direction by a spring or springs..
In the accompanying drawings we have shown our invention as applied to both
single and double flap solitaires. Fig. 1 is a top view of a two flap solitaire taken
on the line of Fig. 3. Fig. 2 is a sectional elevation showing the flaps closed.
Fig. 3 is a sectional elevation of the solitaire in its normal position with the flaps
open. Fig. 4 is an elevation taken at right angles to Figs. 2 and 3. Fig. 5 is an
underside view of the solitaire with the flaps open and Fig. 6 is a side elevation of
the sliding rod detached.
a is a hollow head which receives a disc b. c is a stem or shank which is
secured to the head a by soldering or otherwise, d d are flaps which are hinged to
the shank c, e is a forked rod which is secured to the back of the disc b, (see
Fig. 6). Each prong of this forked rode is pivotted or hinged to one of the
flaps d.
..
In the centre of the head a square hole is formed and the central portion of
the shank c is recessed to receive the forked rod. c. Inside the head, springs ff
are secured which springs press on the underside of the disc and force it outwards
as seen in Fig. 3 thereby drawing on the forked rod with which the disc is
connected and keeping the flaps open..
To insert the fastener in say a wrist band, the disc bis depressed so as to drive
down the forked rod and bring the flaps into the position shown at Fig. 2 in
which position they are passed through the button hole. When through, the
pressure on the disc b is removed and the flaps are drawn by means of the
springs facting on the underside of the disc to which the forked rod is secured
into the position shown at Fig. 4. It will be evident that in place of the forked
rod we may employ two separate rods which will be pivotted both to the disc b
and to the flaps d.
In Figs. 7, 8 and 9 we have shown a slight modification in the means for
depressing the forked rod c. Fig. 7 being a sectional elevation showing the flaps
open. Fig. 8 a similar view taken at right angles to Fig. 7 and Fig. 9 a sectional
plan

page_text: In this modification the head a is hollow as before and the disc b is soldered to
the top. The forked rod e is formed with a large head and carries a coiled spring f.
gg are two wedges which project slightly beyond the head a on opposite sides
thereof in such a manner that they may be pushed inwards The pushing in of
these wedges will drive down the forked rode and close the flaps preparatory to
their being inserted in the button hole. On releasing the pressure the wedges
will be drawn outwards by the action of the spring e which drives up the enlarged
head of the forked rod against the wedges and forces them apart at the same time
opening the flaps.
In Figs. 10, 11 and 12 we have shown our invention as applied to a single flap
back. The single flap d is hinged along; the centre line to the shank c and a
single rode is pivotted to the flap on one side of the centre line. This rod is.
secured to a disc bas in the first described arrangement and by depressing the
disc b the flap d will be caused to rock on its hinges and one half will lie along
side the shank while the other half will project downwards beyond the shank.
It will be evident we may also employ the wedges to drive down the single rod.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is. to be performed we declare that what
we claim is
Constructing studs and solitaires. with a hinged flap or flaps constituting the
back of the stud or solitaire to which we connect a sliding rod or rods for
imparting a rocking motion to the flap or flaps in the manner and for the purpose
above set forth.
