'
The object of this Invention is an improvement in solitaires, whereby the front
and back portions are capable of being opened out or drawn apart without being
entirely separated for facilitating the adjustment of the solitaire upon the shirt
wristband or other article of dress, and to be closed or pushed nearly close together
for securing the two ends of the wristband, and to prevent the back plate of the
solitaire releasing itself from the button hole while the garment is in wear, the
two portions being held secure by a spring appliance in the opened out or in
the closed position.
My Invention consists in fitting on the barrel of the front plate of a solitaire a
collet, or in making the barrel with a projecting ring, over which two "shaped"
ends of a divided collar are compelled to engage by the flexibility of a spring, to
which the two ends are attached or formed as part of same. The spring portion is
preferably of bow shape, and held in position by being placed in the "burred" over
edge of the front plate. The divided collar ends are provided with two clip pieces
projecting slightly over the end of the barrel to engage into one or other of two
annular recesses formed on the stem of the back plate, the stem being free to slide
within the barrel of the front plate to the extent or distance apart only of the two
annular recesses. The portions of the stem between the two annular recesses is
bellied to enable the clips or locking portions of the shaped spring ends to become
released from the recesses and to open out that the bellied portion may pass the
clips remaining in contact with a pressure due to the strength of the spring bow
that the back plate cannot move unless extra exertion be used to overcome that
strength.
Other forms of springs and clip ends may be employed, the essential novelty of
the Invention being a telescopic-actioned solitaire with self locking appliances,
and without becoming separated when the front and back portions are drawn
out.

The object of this Invention is an improvement in solitaires, whereby the front
and back portions are capable of being opened out or drawn apart without being
entirely separated for facilitating the adjustment of the solitaire upon the shirt
wristband or other article of dress, and to be closed or pushed nearly close together
for securing the two ends of a wristband, and to prevent the back plate of the
solitaire releasing itself from the button hole while the garment is in wear, the two
portions being held secure by a spring appliance in the opened out or in the closed
position.

My Invention consists in fitting on the barrel of the front plate of a solitaire a
collet, or in making the barrel with a projecting ring, over which two "shaped"
ends of a divided collar are compelled to engage by the flexibility of a spring, to
which the two ends are attached or formed as part of same. The spring portion is
preferably of bow shape, and held in position by being placed in the "burred" over
edge of the front plate. The divided collar ends are provided with two clip pieces
projecting slightly over the end of the barrel to engage into one or other of two
annular recesses formed on the stem of the back plate, the stein being free to slide
within the barrel of the front plate to the extent or distance apart only of the two
annular recesses. The portion of the stem between the two annular recesses is
bellied to enable the clips or locking portions of the shaped spring ends to become
released from the recesses and to open out that the bellied portion may pass the
clips remaining in contact with a pressure due to the strength of the spring bow
that the back plate cannot move unless extra exertion be used to overcome that
strength.
Other forms of springs and clip ends may be employed, the essential novelty of
the Invention being a telescopic-actioned solitaire with self locking appliances,
and without becoming separated when the front and back portions are drawn
out.
The manner of carrying my Invention into practice is shown in the annexed
Sheet of Drawings.
Figure 1 is a sectional view of the front plate a of a solitaire or stud, which
may be used for either the wrist band, collar, or shirt front, according to the size
of the article and its intended use; b is a barrel on the back of the front plate u,
and has a collet, or it may be a projecting ring c, as shown, for notch portion d of
a bow shaped spring e, Figure 2, to take position and hold itself securely against
vertical action when the stein fand back plate g, Figure 3, are pulled out or pushed
in, the lips h, h, of the spring c engaging themselves in the recess i or j of the
stem f, as the case may be, to lock the article in a closed condition upon the two,
three, or four plys of fabric, or in an open state, to permit of the solitaire or stud
being easily removed in the usual manner. Figure 4 represents in action the
stud or solitaire with the stem pushed in, and in Figure 5 with the stem pulled
out.
Figure 6 represents a stud or solitaire for, say, a shirt front. This solitaire has
a plate upon the stem that the back pleat of the shirt may be lodged between it
and the back shank A, and the front pleat between the plate and the front plate
B, the solitaire being held securely in position on the back pleat by the spring
lips h, h, which engage in the recess i when the stem is pushed, as before explained.
This middle plate arrangement is applicable to other parts of article of dress.
Figure 7 represents in section a front plate with the barrel b attached to the
back shell k.

page_text: In the form of barrel shown in Figure 7 I notch the lower part near the shell /:
for the passage of the two lips h, h, of the spring e, which I purpose (for this
arrangement) to make of the slape shown at Figures 9 and 10, this spring being
of ring shape of flat form to find a lodgment in the "bezel" of the solitaire or
stud, as at Figure 9.
Figure 11 shows this arrangement of solitaire or stud complete with the stemn
pushed in.
This telescopic arrangement of stud or solitaire permits of many modifications of
springs and shape of stems, and also of the recesses into which the lips of the
springs may engage for locking the article in a closed or an open condition, but I
prefer the recesses to be annular that the back plate or the front plate may have
a freedom of action to be turned round upon the stem, or the stem within the
barrel, which in certain cases may be stamped in from the shell or otherwise.
Figure 12 represents in section a wrist or collar stud or shirt stud with my
spring and barrel appliances within the back plate g and shell k, or it may be the
front plate and shell, according to the finish of the article, such as enamelling,
engraving, or mounting of the same.
Figure 13 shows another form of spring for the locking action of my solitaire or
stud stein, the two ends of the metal being turned in and shaped to embrace the
stein to a greater extent than that shown by the other forms of springs heretofore
referred to.
The following important and peculiar features of my Invention are, the stem
can readily be lengthened to facilitate its insertion, and shortened to make it secure
in wear, locking in either the opened or closed positions, but does not separate into
parts.
The advantages resulting from the principle of my Invention are,―
1st. As a shirt stud having a smaller back than is usual it can be casily inserted
without injury to the linen. It is rendered perfectly secure by locking, and as
when locked all friction is avoided it cannot wear the button holes.
2nd. The sleeve or cuff stud combines with tho above advantages great comfort
in wear, as the back being small and shutting close on the linen cannot hurt the
wrist. It is also free from unsightly projections.
3rd. The collar stud readily adjusts itself to varying thicknesses of linen, is
equally comfortable in wear, and is also specially adapted for the wrist bands
where four thicknesses of linen have to be secured.
Having now described the nature of my said Invention, and in what manner
the saine is to be performed, I declare that I claim,―
The improvement in solitaires, whether for cuffs, collars, shirt fronts, or other
articles of dress, whereby a telescopic or pushing in action of a back plate may be
effected to close it against the front plate, or vice versa, and in contact with the
fabric, and a pull out action without separation thereof for enabling the solitaire to
be removed, the solitaire being self locked when the stem is in a closed or an open
position, as herein before described.
In witness whereof, I, the said Ebenezer Dobell, have hereunto set my hand
and seal, this Fourth day of June, in the year of our Lord One thousand
