COLLAR BUTTON WITH DETACHABLE HEAD
Hagbarth Sylvester Christophersen, Odense,
Denmark
Application February 3, 1937, Serial No. 123,911
In Denmark February 8, 1936
1 Claim.
This invention relates to a collar stud of the
ldnd having a detachable separate head, i. e.
a head having no secondary function of main
taining the necktie in its proper position and
being therefore independent of devices con
structed for that purpose.
The object of the invention is to provide an
improved construction of collar stud having a
detachable separate head which will be con
10 venient and effective.
According to the invention, a collar stud com
prises a blade or-plate shaped neck or stem, a
slot or slot like hole in the stem disposed near
the front end thereof and elongated in the direc
15 tion of the length of the stem, and a detachable.
head consisting of a mainly V-shaped resilient
clip of metal wire adapted to be pushed through
the slot in a direction transverse to the stem
until it occupies a position in which it is held
20 ?rmly by its own resiliency.
The invention is illustrated in the accompany
ing drawing, in which:-—
Figure 1 shows the button in side elevation,
with the button head in position.
25
Figure 2 a vertical central section of the button
head, detached from the button.
Figure 3 the button plate and neck in top View,

Figures 4, 5 and 6 two modi?ed constructions
30 of the button head.
' In the construction shown in Figures 1-3, | is
the bottom plate of the button, 2 its blade or‘
plate shaped neck or stem which has a great
width in the direction of the button hole, but only
35 a slight thickness at right angles thereto, 3 is a
hole through the button neck, long in the longi
tudinal direction of the same. The button head,
which is pressed into the hole of the button neck
preferably from above, consists of a resilient,
40
mainly V-shaped, clip made from thin, highly
resilient metal wire 4.
The two branch ends of
the clip may conveniently point upward, when
the button is in position, as shown. One branch
(01. 24-104)
below the metal capsule 5. This bend which also
may be provided on the stationary branch of the
clip may be useful for holding the head in posi
tion, when the same has been inserted in the
button neck, with the metal capsule 5 resting
against the upper or lower surface of the button
neck. This button head is very easily gripped
with two ?ngers and inserted into or removed
from the button neck. It does not matter,
whether the stationary or the movable branch of 10
the head is facing the bottom plate of the button.
Figure 4 shows a modi?ed construction of the
capsule 5 according to Figure 2 and viewed at
right angle thereto.
The top of the capsule is
here provided with a lateral projection 'l which 15
facilitates the removal of the detachable button
head when the head is gripped by two ?ngers,
the nail of one of the same resting against the
underside of the said projection.
The metal capsule 5 is a convenience but no 20
necessity.‘ The head may in fact consist solely
of a resilient metal wire 8 bent into V-shape, as
shown in Figure 5, or it may be shaped as shown
in Figure 6, in which the two branches of the
resilient clip 8 are crossing one another.
25
Also other forms of the button head may be
imagined, which allow the head to be maintained
in position resiliently and securely in the button
neck.
Having now particularly described and ascer
tained the nature of my said invention and in
what manner the same is to be performed, I
declare that what I claim is:—
A collar stud comprising a base; a plate shaped
shank projecting at right angle therefrom and
having an elongated slot therein extending from
a point adjacent its outer end towards the base;
and a detachable head extending through said
slot and consisting of a ?attened metal capsule
of somewhat larger size than the slot, a sub 40
stantially V-shaped resilient clip having one leg
secured at one end of the capsule and the other
leg also confined in the capsule, but freely mov
of the clip is ?rmly pinched, at the top, in a
able towards and away from the ?rst named leg,
45 small flat metal capsule 5, into the cavity of which
whereby, when the clip is inserted into the said
the other branch of the clip extends freely in.
slot in a direction normal to the plane of the
shank the head will be held ?rmly in the said
slot due to the resiliency of the clip.
such a manner, that it can move towards and
away from the stationary branch of the clip, but
cannot get out of the capsule.
50
In the construction shown, the movable branch
of the clip has a small inward bend 6, closely
