Improvements in Fastenings for Solitaires and other analogous
articles.
We TноMAS MORTON, of Lodge Road, Hockley, Tool Maker, and WILLIAM
PEARCE, of 52 Hylton Street, Jeweller, both in the City of Birmingham do
hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in the combination and arrangement of
parts constituting the fastening and unfastening mechanism of what are known as
two part solitaires and other similar articles. Its primary object is to provide a
direct pressure locking action in combination with a part rotating unlocking
mechanism, and in the various parts therefor.
It consists somewhat as follows:-We provide upon the back part a flat tubular
shank whose outer edge preferably terminates with a bead or other similar finish.
At each narrow side of such tube and below the beaded edge beforenamed, an
opening is made for the purpose hereinafter stated. Upon the underside of the
front part is secured a cam plate, having two or four cam surfaces. Preferably
upon the rear of this cam plate is a rectangular shaped projection which takes into
a similarly shaped hole in the collar or back plate to which the solitaire front is
secured, for facilitating the securing of the said cam plate to the collar by
soldering &c. Below such plate is carried an inner tubular shank, similar in shape
to the one already described, and also capable of freely sliding therein.
At each of the narrow sides of this inner tube is also made an opening. At the
upper end of this tube is a circular shell by which it may be connected to the cam
plate aforesaid or its equivalent. Within this inner tube is now placed a double
winged bolt, that is, having a bolt on each side which protrude through the
openings on each side of the tube and also stand forward a little of the outside of
the tube. The lower end of this bolt is made springwise (or it may be in two parts)
so that the two winged parts or bolts may be compressed inwards when desired.
Between the two upright sides forming the bolt is further placed a spring, whose
tendency is always to keep them open, that is, to press the winged bolts beyond
the openings in the tube.
The whole of these parts are now connected to the cam plate, by rolling over
the edge or flange of the tube shell on to the said cam plate, but allowing it freedom
to rotate therein.
In some cases the method of connecting these parts to the collar or back plate
may be modified, as for instance the inner tube may be made without the shell at
its upper end, or if at all, it may be a flat disc only. In the centre of the plate to
which the cam plate is attached is a small hole. A similar countersunk hole is
also made in the bottom or closed end of the inner tubular shank. The double
winged bolt is in this case made in two parts, the lower end of each being bent and
shaped to afford the necessary spring action in themselves. A connecting pin is
now passed through the bottom of the shank, passing between the two parts of the
bolt and also through the hole in the back plate or collar, where it is soldered or
otherwise made fast. The shank and its contents are thus made to partly rotate
upon the said central pin.
Its action is briefly thus:-Upon passing the inner tubular part which is on the
solitaire head, into the exterior tubular part which is on the solitaire back, the
5 outstanding bolts are forced inwards until they come opposite the openings in
the latter, when the spring action at once forces them outwards into such openings,
their upper ends catching underneath the tops of such openings, and thus the two
narts are locked together with a direct straight push.

page_text: To liberate the head of the solitaire, it is only necessary to slightly turn the head
round, when the cam plate compresses or withdraws the two sides of the bolt
within the tube, and the one part is free from the other.
Various alterations may be made in the précise details of this our invention
without departing however from its nature.

COMPLETE SPECIFICATION.
Improvements in Fastenings for Solitaires and other analogous
articles.
We THOMAS MORTON, of Lodge Road, Hockley, Tool Maker, and WILLIAM
PEARCE, of 52 Hylton Street, Jeweller, both in the City of Birmingham 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 improvements in the combination and arrangement of
the parts constituting the fastening and unfastening mechanism of what are knowń
as two part solitaires, or other similar articles.
Its primary object is to provide a direct or straight pressure locking action in
combination with a part rotating unlocking movement, also the improved com-
bination of some of the parts themselves.
We effect these improvements by the mechanism illustrated upon the accom-
panying drawing, upon which are figures and numbers of reference, similar
'numbers referring throughout the several views to the same thing or part.
Figs. 1, to 21, illustrate the details of the 'parts of this our invention in their
various stages of manufacture.
Fig. 22, shows the head portion of the solitaire complete.
Fig. 23, shows the head portion entering the back part ready for being pushed
"down and locked.
Fig. 24, shows the two parts locked together.
Figs. 25 to 30, illustrate the details of a modification in this our invention.
Fig. 31, shows a sectional view of the modified parts put together.
1, is a tubular piece having a back plate 2, and also openings at 3, 3, and beaded
top edge 4.
These combined parts form the back part of the solitaire.
5, is an inner tubular shank, to the upper end of which is attached the shell 6,
and whose lower end at 7, is closed. Openings are also made at 8, 8. 9, is a bolt
'having double wings 10, 10, and projecting pegs 11, 11, at the top of the upright
sides 12, 12. The bottom part 13, is made springy, so that the two upper ends
may be drawn closer together when required. 14, is an expanding spring.
We now take the bolt 9, and place it inside the tubular shank 5, the wings 10, 10,
projecting through the holes 8, 8. The spring is now placed inside the bolt all as
Seen in Fig. 11.
15, is a cam plate, having two recessed cam surfaces 16, 16. This cam plate 15,
is now secured into the shell 6, by rolling over the edge of the latter as shown in
Fig. 15. The shank 5, and shell 6, however, are free to rotate on the said plate 15.
It will be seen that the projecting pegs 11, 11, enter each into the cam recesses 16, 16.
17, is the collar or back plate, which is now secured to the top of the cam plate 15,
see Fig. 21. In this collar 17, is a hole 18, into which is passed the projection :19,
upon the back of the cam plate 15, and then soldered. This makes it firmer than
'if merely soldered.
•
Any desirable front may now be 'attached to the collar 17, when the article is
complete.

page_text: Again in some cases we may modify the method of connecting the inner tube to
he cam plate, also the cam plate may serve as the back plate or collar. This we
ave illustrated in Figs. 25, to 31. In the inner tube 5, is made the hole 20, to
receive the pin 21. At the top of the tube is made a flat disc 6. The double
winged bolt is in this case made in two parts. 9°, is one half of the said bolt
having its lower end bent into a spring form at 22, and thus dispenses with the
previously described spring 14. Two of these half bolts are now placed in the
tube 5, and the pin 21, passed up the hole 20, between them. The cam plate 15*,
is made in one with the collar or back plate 17", and in the centre of the latter a
hole is made through which the pin 21, is passed and there soldered as seen in
Fig. 31. The tube 5*, and its contents are free to part rotate round the central
pin 21.
The action of this our invention is therefore as follows:--Upon passing the
inner tubular part, which is on the solitaire head, into the exterior tubular part
which is on the solitaire back, the outstanding bolts are forced inwards until they
come opposite the openings in the latter, when the spring action at once forces
them outwards into such openings, their upper ends catching underneath the tops
of such openings, and thus the two parts are locked together with a direct straight
push.
To liberate the head of the solitaire it is only necessary to slightly turn the
head round, when the cam plate compresses or withdraws the two sides of the bolt
within the tube, and the one part is free from the other.
The action of the cam plate upon the projecting pegs of the bolt is shown in
Figs. 16 and 17. In Fig. 16, the pegs 11, 11, are shown as when the solitaire is
locked; but upon turning the head round a little way, the pegs are forced along
the sides of the cams and thus compressed closer together as seen in Fig. 17, and
hence the bolts are drawn inwards clear of the holes on the inner tube, when it may
be withdrawn.
If desired instead of using a cam plate having two cam recesses we may use the
plate 23, shown in Fig. 18, in which there are four of such recesses.
Various alterations may be made in the precise details of this our invention
without departing however from its nature.
Having now particularly described and ascertained the nature of this our said
invention, and in what manner the same is to be performed, we declare that what
we claim is :-
1. In fastenings for sleeve buttons, solitaires, shirt and collar studs, and the
like articles, the combination of a direct straight push locking movement, with a
part rotating unlocking movement, substantially as herein described and illustrated
on the drawings.
2. In fastenings for sleeve buttons, solitaires, shirt and collar studs, and the like
articles, the combination with the front and the cam plate 15 or 23, and inner
tube 5, of a double winged bolt having projections 11, 11, and wings 10, 10, sub-
stantially as set forth and illustrated.
3. The combination with the back part of the fastening, of the part rotating front
tubular part 5, having the double winged bolt 9, and spring 14, and cam plate 15,
all as set forth and illustrated.
4. The modified combination with the tubular part 5ª, of a divided double bolt 9*,
as set forth and illustrated upon the drawings.
5. The modified method of connecting the tubular part 5*, having the divided
bolt 9, to the back plate 17", as set forth and shown.
