Improvements in Studs and the like for Fastening Collars, Shirts,
and other Articles of Wearing Apparel.
1, GEORGE MORGAN EVANS, Watchmaker and Jeweller, Lucknow Place,
Ystalyfera, 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 :-
My improved stud or the like for the purposes set out in the title consists
essentially of two parts and the construction will be readily understood from the
accompanying drawings in which Fig. 1 shews the stud when closed and Fig. 2
when it is opened.
Both figures shew the stud in section and similar letters in each refer to the
same parts.
The head a of the stud bas fastened to or forming part of it the tubular stem b.
The stem b is sufficiently large in inside diameter to go easily over the outside of
the tubular part c of the base of the stud. The base proper d is more or less
circular or of any other suitable form and has a rim e all round it. The tubular
part c opens into d. At or near the rim e I provide two supports f, between which
is pivotted one end of the lever g, to the other end of which is pivotted another
lever of about the shape h. The lever h is encircled by a spiral spring i which is
retained in position by the projection j on the lever h, and the projection or ring k
inside the tubular part c. I provide a slide / one end of which passes an aperture
in the rim e and can be pushed to and fro by the upstanding extremity m.
slide is bent or has an opening in it so that when pushed to and fro it will not
interfere with the lever h. The other end of is provided with a projection n
immediately under the lever g.
This
I arrange in making the stud that the lever g is by the action of the spring i
kept lower at the end where it is pivotted to h than it is where pivotted to f, and
the projection n is made of sufficient height that when the slide is drawn out the

the stud, is slid over c and the slide pushed in, whereupon the catch o passes
through the slot r, and catches against the bottom edges of the tube as shewn in
Fig. 1, and prevents the withdrawal of the base from the head.
I have described a stud constructed in accordance with my invention, but I do
not confine myself to the exact proportions, relative positions, or conformation of
the various parts herein before mentioned or referred to as any or all of them can be
varied considerably without departing from the spirit of the invention.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. In studs or the like having the head and base separable from one another, the
combination of levers, slide, projections, spiral spring and catch acting together and
forming an arrangement whereby the bead may be connected with or disconnected
from the base, the whole substantially as described in the above Specification and
exemplified in the accompanying drawing.
Dated this 9th day of September 1895.
