Year: 1876

page_text: LETTERS PATENT to Frederick Weintraud and Richard James Secundus Joyce,
of No 18, Alderinanbury, in the City of London; Manufacturers, for the
Invention of "IMPROVEMENTS IN SOLITAIRES OR SLEEVE AND COLLAR STUDS."
PROVISIONAL SPECIFICATION left by the said Frederick Weintraud and
Richard James Secundus Joyce at the Office of the Commissioners of Patents
on the 31st August 1876.
FREDERICK WEINTRAUD and RICHARD JAMES SECUNDUS JOYCE, of No. 18, Alder-
manbury, in the City of London, Manufacturers. "IMPROVEMENTS IN SOLITAIRES
OR SLEEVE AND COLLAR STUDS."
This Invention relates to improvements in solitaires or sleeve and collar studs.
Hitherto it has been the practice to make solitaires or studs with a couple of
spring catch plates, which can be.pushed in by the hand when desired to release the
stem for the removal of the article from the sleeve or collar, the spring or springs
returning the plates to their normal position, that the shank when pushed in may
exert a pressure and force the plates apart for its rim to pass the plates, then
returning under the action of the springs for the shank to become engaged and the
solitaire to be thereby secured. Now it has been found that the smallness of the
chamber in which to place the springs limits their action and causes frictional
contact upon the coils or helices, that the springs after a little while refuse to act,
consequently great difficulty is experienced by the wearer both in putting the
solitaire in place in the sleeve or collar and in removing it therefrom.
By our Invention the chance of the above difficulty happening is avoided,
and the solitaire is capable of being opened or closed with greater facility and
certainty.
The Invention consists in fitting a sliding plate between the two shells forming
the back and tho inner plates of a solitaire, that it may be moved outwards by a
withdrawal pressure upon or against a knob, a button, or a ring on its outer end.
The sliding plate is formed with a tongue which is capable of springing into a
recess formed in the inner plate, for the purpose of making the sliding plate remain
Dine 21

page_text: in its position after having been pushed back, and to limit the distance to which the
slider plate can be drawn out.
The inner plate has a recess across it in which the sliding plate is free to move,
and is so arranged as to preserve its direct to-and-fro travel.
The inner end of the sliding plate has a semicircular recess or notch for taking
over the rim of the shank after the stem has been pushed into the shank, the sliding
plate being then pushed in for fastening the solitaire.
In opening this solitaire the sliding plate has only to be pulled outwards by its
knob or ring when the front portion can be removed.

the said Frederick Weintraud and Richard James Secundus Joyce in the
Great Seal Patent Office on the 28th February 1877.

This Invention relates to improvements in solitaires or sleeve and collar studs.
Hitherto it has been the practice to make solitaires or studs with a couple of
spring catch plates, which can be pushed in by the hand when desired to release the
stein for the removal of the article from the sleeve or collar, the spring or springs
returning the plates to their normal position, that the shank when pushed in may
exert a pressure and force the plates apart for its rim to pass, the plates then
roturning under the action of the springs for the shank to become engaged and the
solitaire to be thereby secured. Now it has been found that the smallness of the
chamber in which to place the springs limits their action and causes frictional
contact upon the coils or helices, that the springs after a little while refuse to act,
consequently great difficulty is experienced by the wearer both in putting the
solitaire in place in the sleeve or collar and in removing it therefrom.

.
The Invention consists in fitting a sliding plate between the two shells forming
the back and the inner plates of a solitaire, that it may be moved outwards by a
withdrawal pressure upon or against a knob, a button, or a ring on its outer end.
The sliding plate is formed with a tongue which is capable of springing into a
recess formed in the inner plate, for the purpose of making the sliding plate remain
in the locked position after it has been pushed in. The tongue also limits the
distance to which the slider plate can be drawn out by its contact with the edge of
the outer shell.
The inner plate has a recess across it in which the sliding plate is free to move,
and is so arranged as to preserve its direct to-and-fro travel
The inner end of the sliding plate has a semicircular recess or notch for taking
over the rim of the shank after the stem has been pushed into the shank, the sliding
plate being then pushed in for fastening the solitaire.
In opening this solitaire the sliding plate has only to be pulled outwards by its
knob or ring when the front portion can be removed.
Our Invention will he clearly understood by the annexed Drawings, in which
Figure 1 represents a detailed view of the sliding plate a with its knob b, by which
it can be drawn out by the pressure of the thumb or of the thumb and finger, to
release the forked end c from its contact with a rim d on the inner end of the
tubular stem e, shown detached in Figure 2, which tube takes over a plug stem m
projecting from an inner plate 2. The other end of the stem has a shank plate fas
on ordinary solitaires of this kind. The sliding plate a has a tongue g to ride upon

page_text: a sunken portion of the inner plate i, shown separately in Figure 3, the sunken
portion itself forming a groove in which the sliding plate a can be moved to and
fro. The tongue g takes into the recess h when the sliding plate a is pushed
nwards, and serves as an abutment to hold the sliding plate in a locked position.
The sliding plate a is held in the groove of the inside plate by the touch of the side
walls of the groove which it fits, and also by the tension of the tongue, which serves
also as a spring and becomes depressed when riding over the flat portion of the
sunken part of the inner plate between the recess h and the inner periphery of the
outer or back shell 3, shown separately in Figure 4. The up pressure of the spring
tongue g is resisted by the fit of the back shell, between which and the inner plate
the sliding plate a moves, as is more particularly shown in the sectional view
Figure 5, in which the sliding plate is represented as pushed in and the shank
locked.
Figure 6 represents a backing of paper, leather, or other material, which is fitted
in between the inner plate i and the face of the solitaire, which face may be of
glass or other body, ornamented or enamelled or not, as desired.
The sliding plate a is prevented leaving the solitaire when it is drawn outwards
to release the fastening by the tongue g taking against the inner periphery of the
back shell j, as in Figure 7.
We are aware that springs to act upon or against bolts or catches have been used
in solitaires and collar studs as locking mediums to catch and lock the.shank tube
within the body of the article, and therefore forms no part of our claim, but what
we do consider novel and as our present Invention which we do claim is,―
Firstly. The construction and employment of a sliding plate with single or double
legs at one end, to engage into or against a shank to form the locking medium
within a solitaire or like article, as described and shown in the annexed Drawings.
Secondly. We claim the combination of a grooved and recessed inner plate with a
sliding plate within, or to solitaires or like article, as described and substantially as
shown.
In witness whereof, we, the said Frederick Weintraud and Richard James
Secundus Joyce, have hereunto set our hands and seals, this Twenty-eighth
