COMPLETE SPECIFICATION.
An Improved Collar Stud, Solitaire, or the like.
I, PERCY BISHOP HUTCHINSON, Dental Surgeon, 22 Park Street Walsoken,
Cambs do hereby declare the nature of this invention to be as follows:-
My invention relates to an improved collar stud, solitaire or the like, and has for
its object to provide a collar stud, solitaire, or similar article, the two parts of
which will be readily detachable and attachable, to facilitate the insertion into a
shirt collar, cuff, or the like while at the same time the two parts of such stud
solitaire or the like will not when attached one to the other be liable to accidentally
come apart or work loose.
And in order that the said invention may be the more readily understood I have
shewn same upon the accompanying sheet of illustrative drawings, wherein :-
Fig. 1 is a sectional elevation Fig. 2 a plan of the underside with the cap
removed.
Figs. 3, 4, 5, and 6 are details of the invention (like letters of reference indicate
corresponding parts throughout the figures).
Referring to the drawings a is a steel or other stud shank having a head a¹ at
one extremity and with its other end a' fashioned similar to the head of a crochet
hook, as shewn in Figs. 1 and 3 that is to say it terminates in a point and has a
piece cut out of one side thereby forming a flange at the lower end of such cut-away
part.
This shank a fits into an outer shank or sleeve b formed at one end with a disc
or base b¹ on the under side of which is fixed at 62 a spring c of the form shewn, the
end c' of which spring normally takes up its position over the mouth of the outer
shank or sleeve b.
In operation the shank a is inserted into the upper end of the outer shank or
sleeve and pressed down into same, the head of the said shank a partially
displacing the spring in its passage or pushing same aside until such head a
has passed the spring e, whereupon the latter returns to its normal position and
lies behind the flange and close against the cut-away side, thereby preventing
the withdrawal of such head until same is given a half-turn by means of the milled
head a', whereupon the rounded perpendicular side of the shank a is caused to
present itself to the spring cand consequently allows such headed shank to be easily
withdrawn.
A cap
d is provided, which would be soldered or otherwise secured to the under
side of the disc or base 61, and is formed with a recess or socket d'into which the
head as of the shank a fits when the same is pressed home (Fig. 1).
The disc or base b¹ has preferably formed around its periphery a raised rim 6* so
that when the cap d is fixed upon such disc or base 6 a space is left between the
cap d and the said disc or base 6', as shewn in Fig. 1.
Having now particularly described and ascertained the nature of this said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. In a collar stud, solitaire, or other similar object, the arrangement of the parts
for attaching and detaching the two separable parts, consisting of a shank having a
tapered head flanged on one side at one extremity and provided with a milled head
at the other end, in combination with a receiving shank or sleeve substantially as
described and illustrated.

page_text: 2. In a collar stud, solitaire, or the like, the receiving shank consisting of a sleeve
having at one end a rimmed dise or base provided with a spring constituting
catch for engaging with and holding the flanged head of the inner shank, such disc
or base being closed by a recessed cap, substantially as and for the purpose
described and illustrated.
