Improvements in studs and solitaires
Year: 1886

page_text: I JOHN COMPTON WEEKS JEFFERYS of 19 Hargrave Park Road, Holloway in
the County of Middlesex Manufacturing Jeweller do hereby declare the nature of
this invention to be as follows:-
This invention relates to certain Improvements in studs and solitaires the same
being applicable to that class of articles referred to under my former Patents
No. 15213 dated 19th November 1884, and. No. 7574 dated 22nd June 1885 and
No. 628 dated 14th January 1886; the object being to provide a spring sleeve to
cover the pillar of the stud, solitaire or such like article and to form the centre
pillar with a flat side or sides or enlargement thereof so that in turning the parts
of the stud around to bring the lower movable part or parts into locked position
the flat or flats or enlargement of the centre pillar will act as a cam or eccentric
to "spring" the sleeve apart or open or so as to exert its resillient force to act
more powerfully upon the parts than can be done with the spring as hitherto
employed in such like articles. Further the stamped springs and plates hitherto
used may be dispensed with in employing this invention and so cheapen the
production of such studs by so much.
This preceeding description will be clearly understood from perusal of the said
former specifications or by comparison with the well known "Jeffery's Bi-climax
Solitaire" already on the market.
The sleeve will be made conveniently from drawn tubes of eliptical or flat cross-
section and then applied as a cover to the main pillar of the solitaire.
The lengths of tube so employed may be cut across on one side by a cut
diagonal or otherwise so as to form two open portions or arms of the sleeve which
will be expanded and will act as springs by reason of the turning of the camlike
centre pillar.
In a modification of this invention the said spring sleeves will not be cut
through but will be continuous and in this case the drawn flat tubes will be
corrugated or fluted vertically so allowing of expansion and contraction by turning
the parts with the centre pillar or in its contracted form serving as spring stop to
hold the parts in open or locked positiou.

the County of Middlesex, Manufacturing Jeweller, do hereby declare the nature of
this invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-
This invention relates to certain Improvements in studs and solitaires, the same
being applicable to that class of articles referred to under my former patents
No. 15213 dated 19th November 1884 and No. 7574 dated 22 June 1885 and
No. 628 dated 14th January 1886, the object being to provide a spring sleeve to
cover the pillar of the stud or solitaire or such like article and to form the centre
pillar with a flat side or sides or enlargement therof so that in turning of the
stud around to bring the lower movable part or parts into locked position, the flat
or flats or enlargement of the centre pillar will act as a cam or eccentric to
'spring" the sleeve apart or open so as to exert its resillent force to act more
powerfully upon the parts than can be done with the springs as bitherto employed
in such like articles. Further the stamped springs and plates hitherto used may
be dispensed with in employing this invention, and so cheapen the production of
such studs by so much.
<<
This preceding description will be clearly understood from perusal of the said
former specifications or by comparison with the well known "Jeffery's Bi-climax
Solitaire" already on the market.
The sleeve will be made conveniently from drawn tubes of elliptical or flat cross
section and then applied as a cover to the flat pillar of the solitaire. The lengths
of tube so employed may be cut across on one side by a cut diagonal or otherwise
so as to form two open portions or arms of the sleeve, which will be expanded and
will act as springs by reason of the turning of the cam like centre pillar.
In a modification of this invention the said spring sleeves will not be cut
through but will be continuous and in this case the drawn flat tubes will be
corrugated or fluted vertically so allowing of expansion and contraction by turning
the parts with the centre pillar or in its contracted form serving as spring stop
to hold the parts in open or locked position.
In the accompanying sheet of drawings Fig. 1. is an under plan view partly in
section of a stud or solitaire constructed according to this invention, with the
shoe or foot plates removed in order more clearly to show the section of centre
pillar and the spring sleeve piece-said shoe plates being indicated in dotted lines
as in the position for entering the button hole.
Fig. 1 is a vertical section of the stud complete (without the head ornament).
Fig. 2 is a like view to Fig. 1. showing the foot plates partly opened by revolving
the head and centre pillar and expanding the spring sleeve. Fig. 2ª being a
vertical section thereof on line x.
Figs. 3. 3 4 and 4ª are similar views showing a modification of the invention
by the employment of a centre pillar and spring sleeve. of corrugated or fluted
section.

page_text: In Figs. 3 and 3º the foot plates are shown as when locked in the fully opened
position and Fig. 3b is a side view from the right of Figs. 3 and 3*.
Figs. 5. 5 5b 6. 6" 6" 7. 8 and 8ª are details of parts and modified forms of the
spring sleeve.
Figs. 9 and 10 show the spring sleeve applied to a stud or solitaire of the class
referred to in my former letters Patent No. 7574 dated 22 June 1885 'and
represented in Figs. 1 and 10 of the drawings accompanying the said specification.
a is the head of the stud or solitaire which will receive such ornamention or be
covered by, or will receive a plate of precious or superior metal as required.
b is the spring sleeve, drawn as described and of section required as seen in
Figs. 1. 2. 3. 4 and 8, and in dotted lines Figs. 9 and 10 of the drawings. The
spring sleeve b may be stamped out as shown in Fig. 8 and be bent to the form as
shown in Fig. 8³, it may also be fluted or corrugated.
The centre pillar g is shown in Figs. 1 and 2 flatted on the sides which acts
when turned by the head (and with it the foot plate g¹ or round back f) as a cam
to spring the sleeve b open as shown in Fig. 2. or as shown in Figs.
and 4 &
fluted centre pillar ġ is used with the corrugated sleeve b and acts similarly.
The part d, c shown in Figs. 5. 5ª and 5b detached, turns freely about the centre
pillar g; and is restrained only by the spring sleeve b. The action of the parts of
the solitaire shown in Figs. 9 and 10 are, as before stated, the same as is described
in reference to and shown in Figs. 1 and 10 of the drawings of the Specification
of my former patent No. 7574 dated 22 June 1885 but simplified by the application
of the spring sleeve b instead of the spring plate and springs a³ a* of the said
specification.
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
In a stud, solitaire, button or such like article, having a turning pillar g, the
spring sleeve b, acted upon, and brought into action by the turning operation of
the said pillar g, of the stud or solitaire body, constructed and operating as and for
the purpose herein set forth.
