PROVISIONAL SPECIFICATION.
Improvements in Studs, Solitaires, and the like.
We THOMAS MORTON, and JOHN HENRY CROWDER, both of 405 Lodge
Road, in the City of Birmingham, Manufacturers, do hereby declare the nature of
this invention to be as follows:-
This invention relates to improvements in studs, solitaires, and the like, in which.
such articles consist of two parts, and consists primarily in the improved means-
by which the removable front part or head of the stud is secured to the back.
The said front or head consists of the stud front or ornament proper to which
is attached a stem or leg. At or near the outer end of this leg, an all around
groove is made, and the extreme is preferably pointed or coned.
Again. The back is formed, having a tubular stem, and a somewhat bell-
mouthed back plate or flange to which is attached an outer backplate so as to
provide a hollow space between such two back plates. Between such two back.
plates, and usually secured in the aforesaid flange-is a steel spring claw disc..
This steel spring claw disc, is cut and perforated, so as to leave a diametrical
cross bar, sufficient metal however being left upon each side of this bar, which,
when turned up, and suitably shaped towards each other, shall form spring claw
clips which may take into or engage with the groove in the stem aforesaid of
the front part. Preferably a central hole is also perforated in the cross bar, so
that the point of the stem shall have freedom, and also that any accumulative
dust &c. may fall therethrough.
Its action will now be readily understood:-When the stem of the front part
is pressed down into the tube of the back part, its front end is forced between
the claws which occupy a place in the bell mouthed part of the flange, until they
fall into the groove with a click, and firmly holds it there. By however applying
a similar force, it may be withdrawn.

We, THOMAS MORTON, and JOHN HENRY CROWDER, both of 405 Lodge.
Road, in the City of Birmingham, Manufacturers, 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 studs, solitaires, and the like, in which
such articles consist of two parts, and consists primarily in the improved means by
which the removable front part or head of the stud is secured to the back.
I have appended hereunto an illustrative drawing to which reference is herein
made.
Fig. 1, is a general view of the front or head part of the stud &c.
Figs. 2 and 3, are detail views in sectional elevation and plan of the tubular stem

page_text: Figs. 4 and 5, are detail views in elevation and plan of the steel spring
claw disc.
Figs. 6 and 7, are detail views of the back cover plate.
Fig. 8, is a sectional view showing the stud complete with the two parts attached
to each other.
The front or head consists of the stud front or ornament proper 10, to which is
attached the stem or leg 11. At or near the outer end of this leg, an all round
groove 12 is made, and the extreme end 13 is preferably pointed or coned.
Again. The back is formed, having a tubular stem 14, and a somewhat bell-
mouthed back plate or flange at 15, to which is attached an outer backplate 16, so
as to provide a hollow space between such two back plates. Between such two
back plates, and usually secured in the aforesaid flange-is a steel spring claw
disc 17. This steel spring claw disc, is cut and perforated, so as to leave a
diametrical cross bar 18, sufficient metal however being left upon each side of this
bar, which, when turned up, and suitably shaped towards each other, shall form
spring claw clips 19, 19, which may take into or engage with the groove 12, in the
stem aforesaid of the front part. Preferably a central hole at 20 is also perforated
in the cross bar 18, so that the point 13, of the stem shall have freedom, and also
that any dust &c. may fall therethrough.
Its action will now be readily understood:-When the stem 11, of the front
part, is pressed down into the tube 14, of the back part, its front end is forced
between the claws 19, 19, which occupy a place in the bell mouthed part of the
flange, until they (the said claws) fall into the groove 12, with a click, and firmly
holds it there. By however applying a similar force, in the opposite direction it
may be withdrawn.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :
In a stud, solitaire or the like, the combination with a front such as 10, having a
stem 11, with groove 12, of a tubular back part having within it the steel plate 17,
upon which are formed the claws 19, 19, as shown and specified.
