PROVISIONAL SPECIFICATION.
A Quicker and More Secure Fastening for Solitaires, Diamond
Stars, Pin and Stud, and all Ornaments that are Transferable.
ALFRED ERNEST EVANS 54 Deburgh Road South Wimbledon Surrey do
hereby declare the nature of this invention to be as follows:-
It is intended to use a bolt and spiral spring on the back piece and a key'd tube
on the front piece so that when the two pieces are brought together and pressed
and turned half way round at the same time, the bolt will fly up and lock itself and
will not come unfastened unless pressed and turned round at the same time; which
will give greater security and be much quicker than the means usually adopted.

This invention relates to studs or solitares and consists in a quicker & more
secure fastening for the heads of same, or ornaments that are transferable from a
pin to a stud or vice versa; the same being carried out as follows.
The upright or stem of the stud is formed hollow and contains a spring the
upper end of which acts upon a pin sliding in slots in the stem this pin carries
with it a collar surrounding the stem of the stud which, at its upper extremity has
two projections which enter a slot in the head of the stud and upon turning the
head to the right and at the same time exerting a slight pressure the aforesaid
projections will enter annular grooves in the head, and will be held in position by
depressions in said annular grooves and the action of the spring aforesaid.
