PROVISIONAL SPECIFICATION.
Improvements in Shirt-studs.
1, ALBERT ADAMS of 13 & 14 Cornmarket Street Oxford Wine Merchant's
Assistant do hereby declare the nature of this invention to be as follows:-
This invention has for its object an improved construction of shirt stud; applying
specially to such studs, as secure the collar to the shirt.
The improvement consists in making the stud so flexible as to cause no undue
pressure upon the throat, or chest.
In order to accomplish this object, I construct the stud as follows:-
A piece of metal wire possessing the necessary elasticity is coiled round in a
close spiral; forming the disc-like base of the stud. That end of the wire which
is nearer the centre of the disc, is then coiled around a suitable mandril, and forms
the stem of the stud; the mandril being withdrawn.
The small head of the stud may then be secured to the stem by soldering, or
other means.
Or; the base having been coiled as above described; the head, and stem of the
stud may be secured to the base, by means of solder or otherwise.
Dated this 20th day of January 1891.

COMPLETE SPECIFICATION.
Improvements in Shirt-studs.
I, ALBERT ADAMS of 29, Storer Road, Loughborough late of 13, and 14 Corn-
market Street Oxford Wine Merchant's Assistant 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 of this invention is to construct shirt-studs in such a manner that,
while securely fastening the shirt, or collar, they will be so flexible as to cause no
injurious pressure upon the chest, or throat of the wearer.
To this end, the invention consists in the novel construction hereinafter described,
and claimed, whereby said end is attained.
The invention is illustrated in the accompanying drawings.
Figure 1 represents a side elevation of the shirt-stud,
Figure 2 a plan of the same,
Figure 3 is a side elevation of a modified form of stud,
Figure 4 is a sectional plan of the said stud.
Similar letters of reference designate corresponding parts in all the figures.
A represents the flexible base of the stud, made up of metal wire, coiled into the
form of a spiral; the innermost end of the wire being coiled into a cylindrical
spiral, forming the shank of the stud as shewn at B in Figure 1. The head of the
stud is firmly secured to the said cylindrical-spiral shank, preferably by solder.
Figure 3 designates the stud having a flexible spiral base A; the inner end of
the coil A being firmly attached, at Ď, to the tubular shank B, of the stud; the
connection being made preferably by means of solder.
The head of the stud C, which may be set with precious stones, is fixed securely
to the shank B, or the head may be made in one piece with the shank.
The flexible base of the stud allows of considerable angular motion of the
shank B, about its point of attachment to the coil A; whereby such lateral strains

page_text: as may come upon the shank have no tendency to cause the base of the stud to
press unduly upon the wearer.
The coiled cylindrical stem B in Figure 1. gives greater flexibility to the stud,
and at the same time facilitates the insertion of the head of the stud through the
holes left for that purpose.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, declare that what I
claim and desire to secure by Letters Patent is :
A shirt-stud having a flexible base, made up of a spirally-coiled wire; the said
flexible base being firmly attached to the cylindrical, or spirally coiled shank;
substantially as and for the purpose herein described.
