of the Commissioners of Patents, with his Petition, on the 6th
July 1874.
.I, THOMAS KENDRICK, of Balsall Heath, in the County Worcester,
do hereby declare the nature of the said Invention for "CERTAIN IM-
PROVEMENTS. IN THE CONSTRUCTION AND FASTENINGS OF SOLITAIRES, SLEEVE. LINKS,
STUDS, AND OTHER ARTICLES OF JEWELLERY," to be as follows:-
-
This Invention relates to improvements in the construction and
fastenings of solitaires, sleeve links, studs, and other articles of jewellery
and consists in the various arrangements herein-after described.
In Fig. 1 of the accompanying Drawings A is a view of the link
complete, and B is a view in section; b is a band spring (or a spiral onc
may be used); c is a movable plate through which the shank & passes;
e is the base; C is an under view of the plate c. In adjusting the link
press upon plate c, whereupon the spring will yield inwards, the aperture
9 in the shank will be exposed to receive the shank of base e, and on
removing the pressure the fastening will be secure. To release, reverse
the action.

page_text: In Fig. 2 A is a view in section, b is a wire or bar on which
slides the spiral spring c, and lips or buttons d; the said lips pass
through a slit or aperture in the base, thereby keeping them straight,
but allowing them to work freely; the slit is shewn in back view e;
or I dispense with spiral spring and substitute a band spring. In this
case I make one lip or button permanent, the other to work in the slot,
its inner end being acted upon by the said spring, thereby allowing it to
retain any desired position. To attach, according to the first part of this
design, place either of the lips through the button holes, and with
pressure the spiral spring will yield, allowing the other lip to pass
through, and upon loosing, the force of the spring will place or force the
lips apart and to each end of the button holes, holding the stud
securely.
In Fig. 3 A is a view in section, & is the bottom part of solitaire the
shank of which passes through the tube c which is round. The shank
has a square foot or shoulder d which is kept in the desired position by
the pressure of the spring e. To attach to the shirt or cuff, place the
solitaire through both button holes, turn the bottom part or cross bar ba
quarter round, and it will be secure until the action is reversed.
"
In Fig. 4 A shows the design complete; b is the back of a with a
volute opening or slot c; d is a plate of metal free to rotate at the back
of b, but held together by the pin e; f,f, are legs or lips, one of which is
fixed to d, and the other loose to work in a straight slot g. By turning
6 round, it forces by means of the volute slot the loose leg in the opposite
direction to the fixed leg, causing them to occupy a position at the
extreme end of the button holes in which they had been previously
placed. To release, reverse the action of b.
In Fig. 5 A is a sectional view; B, an under view; and C, a view of
device complete, with base compressed to pass through hole in shirt to
secure same; a is the base which has a hinge joint; b is a spiral spring
in the tube or stem, pressing upon a, and causing it to retain its
position.
