COMPLETE SPECIFICATION.
Improvements in Studs and Solitaires.
I HENRY THOMAS OCTAVIUS JONES of 95 Chatsworth Street, Liverpool in the
County of Lancaster Gentleman 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 :-
The object is to provide studs or solitaires so constructed as to be readily
introduced into position and when so introduced be securely retained.
My invention consists essentially
:-
In the combination of a suitable head with a fixed pivotted or flexible shank,
such shank being provided with two swivelling bars recessed or otherwise made
so as to become locked when required, at right angles to each other.
DESCRIPTION OF THE DRAWINGS.
Figs. 1 and 2, are perspective views of a stud or solitaire under my invention in
which a head a is secured to one end of a shank b, the other end of which is
fitted with cross-bars c, d, one or both of which are free to turn or swivel on
the said shank. The said crossbars are formed with locking recesses e which
hold the said bars in the position shown in Fig. 1. To prevent the said bars
from becoming unlocked and assuming the position shown in Fig. 2, a spring is
advantageously used. When the bars are in the position shown in Fig. 2 the stud
or solitaire may be readily placed in and removed from position.
Fig. 3 is a perspective view of a modified stud or solitaire in which the shank
is divided and connected by a link y.
Fig. 4 shows a modification in which both ends of the shank are fitted with
crossbars. The shank is here shown in two parts connected by a link but it may
be in one part only as shown in Figs. 1 and 2.
Figs. 5 and 6 are elevations and Fig. 7 is an end view of a stud or solitaire
under my invention in which the shank b is loose from the head a, and has one
of the crossbars c attached to it whilst the other crossbar d is made with a locking
Prie 8d1

page_text: recess e and is attached to the head a. The bars c, d, are shown in locking position
in Figs. 6 and 7.
In all the views the same letters denote like parts.
It will be evident that only one of the bars may be secured to form a lock and
that many shapes of heads, bars, and locking recesses and projections may be used
and that springs may be placed in any suitable position to retain the bars locked
without departing from my invention.
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 :-
First. The combination of crossbars and shank for the purpose set forth.
Second. The combination of a head, crossbars, and shank for the purpose set
forth.
Third. The combination of a head, crossbars, shank, and locking devices for the
purpose set forth.
