IMPROVEMENTS IN SOLITAIRES, STUDS, SLEEVE LINKS, AND OTHER LIKE ARTICLES
Year: 1878

page_text: LETTERS PATENT to Oliver Prust Martin, of Edgbaston, in the County of
Warwick, Jeweller, for the Invention of "IMPROVEMENTS IN SOLITAIRES,
STUDS, SLEEVE LINKS, AND OTHER LIKE ARTICLES."
PROVISIONAL SPECIFICATION left by the said Oliver Prust Martin at the
Office of the Commissioners of Patents on the 31st May 1878.

LIKE.
Solitaires are generally so constructed as to have a straight stem, and at the
extremity thereof a back rigidly attached thereto. Instead of this I provide in.
place of the said straight stem two arms springing from the centre, and raised to a
point equidistant from each other. They are by preference curved in form, and
they are caused to hold at their extremities a back, circular in shape, which swings
readily in an axis provided. Thus when it is desired to insert the stud into the
cuff or linen the circular back is swung within the arms, so as to enter the button
hole easily in a lengthwise direction, and when it is once through the aperture it is
at once secured in its position by being turned half round.
The same principle of a revolving back herein-before described may, if desired,
be so applied as to allow the back to revolve outside (instead of inside) the arms,
as will be readily understood.

Solitaires are generally so constructed as to have a straight stem, and at the
extremity thereof a back rigidly attached thereto. Instead of this I provide in
place of the said straight stem two arms springing from the centre, and raised to a
point equidistant. They are by preference curved in form, and they are caused to
hold at their extremities & back, circular in shape, which swings readily on an axis
provided. Thus when it is desired to insert the stud into the cuff or linen the
circular back is swung within the arms, so as to enter the button hole easily in a
lengthwise direction, and when this back is once through the aperture it is readily
secured in its position by being turned half round.
That my Invention may be fully understood I have annexed Drawings thereof
which I now proceed to describe.
There are eight Figures in the Drawing, and similar letters of reference indicate
similar parts in all the Figures.
A is the front of the stud, shewn in elevation in Figs. 1 and 3, in section in
Fig. 2, and in plan in Figs. 4 and 5. B, B, are two curved arms projecting from
the front A, and having their extremities united by a pivot bar C, which has a
rectangular section, as shewn in Fig. 2.
The back of the stud consists of two discs D and E, held together by means of
their raised edges D', E¹, as seen in Fig. 2. The pivot bar C traverses the space
between the two said discs,and lies in a slight recess F, formed in the disc D, being
held in place by a flat transverse blade spring G, seen in Fig. 2, and shewn in detail
in Fig. 8.
The rim of the disc D is notched at its opposite sides, as seen in Fig. 6, and the
rim of the disc E is similarly notched, as shewn in Fig. 7, for the purpose of ad-
mitting the pivot bar C when the two discs are placed together, so as to enclose the
said pivot bar.
In Fig. 1 the back is shown in a position for being passed through a button
hole.
In Figs. 2 and 3 the back is shewn turned into a position parallel with the
front A, so as to secure the stud in the button hole.
The action of the spring G upon the square pivot bar C is such as to cause the
back to retain either of the aforesaid positions, and to require some degree of
force to turn it from one position to the other.
Having now described the nature of my Invention, and the manner in which
the same may be carried into effect, I desire it to be understood that I do not
limit myself to the precise details herein-before described, and illustrated in the
accompanying Drawings, as the same may be varied or modified to some extent
without departing from the nature of my said Invention, but what I do claim as
the Invention to be protected by the herein-before in part recited Letters Patent is,
connecting the back of a stud, solitaire, or other similar article with its front by
means of two arms springing from the centre of the back of the said front plate,
and raised to a point equidistant, and holding at their extremities a back or disc
which swings readily on the axis provided, so as to allow the said back or disc to
make a complete revolution when required, and to enable it when turned half round
to enter the button hole in the plane of the suspending arms, and when through the
button hole to be secured in position by being turned half round so as to bring it

position, substantially as herein-before described, and illustrated in the accompany-
ing Drawings.
In witness whereof, I, the said Oliver Prust Martin, have hereunto set my
hand and seal, this Twenty-seventh day of November, in the year of our Lord
One thousand eight hundred and seventy-eight.
