My present invention relates to dress orna
ments, and has particular reference to a new and clasp;
Figure 3 is a view similar to Figure 2, showing
improved type of clasp ornament.
While I have disclosed my invention as applied
to a clasp ornament, it is to be understood that
as to certain phases thereof it is not. necessarily
restricted to such application.
'
It is among the general objects of my inven
tion to provide, in a dress ornament of the clasp
10 type, novel means for locking the clasp so as to
prevent its opening when it is in use, as when it is
mounted on an article of apparel.
While other types of locking arrangements for
dress ornaments, and in particular for clasp or
15 naments, have heretofore been attempted, they
are usually relatively complicated, inefficient, and
unreliable in operation, cumbersome, unattractive
in appearance, and relatively expensive to manue
facture. Many of them are further of limited
20 utility because their locking mechanism is only
operative in a few positions of the clasp and or
nament members, so that the clasp may be safe~
one of the locking positions of the locking ar
rangement;
Figure 4 is an enlarged sectional view substan
tially on the line 4——4 of Figure 3; and
Figure 5 is a side view of Figure 1.
In the drawing, l0 indicates one of the mem
bers of a clasp ornament, while l2 indicates the 10
other member. One of these parts, as the mem
ber l0, may be ornamentally contoured and sur
faced and will hereinafter be referred to as the
ornamental member; while the other member
I2, which is intended to oppose the member ID in
the clasping or clamping function, will herein
after be referred to as the clasp member; and
these parts are pivotally united by the arrange
ment about to be described, whereby they may
be brought into substantially parallel superposed
relation as shown in full-lines in Figure 5 or into
a spread or opened relation as shown in dot-and
dash lines in Figure 5.
The clasp member I2 is shown as provided with
an inturned portion l4 having pintles or trun 25
nions l6 extending therefrom. The latter are
adapted to be received within ori?ces 28 in the
upstanding or out-turned ears I8 of a bearing
plate 20 that is carried by-the ornamental mem
ber 10, being fastened thereto in any suitable
manner, such as soldering. These parts func

invention to provide in a dress ornament, such prongs 22.

as a clasp ornament, locking means in the form ornament in position after they have engaged a

overcome these objections by providing a locking
arrangement in a dress ornament that is simple,
effective, unobtrusive, and inexpensive to manu

Figure 1 is a rear plan view of a clasp orna
ment showing my invention applied thereto;
Figure 2 is an end view, on an enlarged scale,
55 with the locking means in inactive position, that
projecting outwardly therefrom.
It will be observed that by turning the cam
24 about its axis, it may be caused to assume
(a) a position such as indicated in Figure 2 55

in which its lobe portion 24' is out of engage
ment with the plate 2%, thereby permitting the
clasp member 92 to move freely about the hinge
axis, or (b) a position shown in Figure 3 in
which its lobe portion 24’ frictionally engages

thickness.
It will be understood further that by proper
the plate 23] and thereby limits the extent to
tion between the contacting parts to prevent any
possibility of the cam moving as a result of
which the members i@ and 52 may be separated.
Since the cam engages the plate ‘is on one
side of the hinge
as clearly appears from
it is obvious that movement
10 Figures 1 and
of the member 52 is limited only in one direc
tion by the cam. Movement of the member i2
in the other direction, however, is limited by
the fabric against which the ornamental mem
ber l8 may be caused to press.
In Figure ‘l, I have indicated the locking posi
design, the pitch of the cam surface may be so
proportioned that there will be su?‘icient fric
pressure of the member l2 against it. This result
may be secured by making the cam 21% of circular
contour, as illustrated, although it will be under- 10
stood that I do not’ necessarily restrict myself to
such circular contour.v
In general, it will be understood that changes

art without departing from the spirit and scope
of the invention as expressed in the appended
claims. It is, therefore, intended that these de

when the clasp members HQ and i2 are in face~
to-face relationship, as shown.
by engagement ti ereoi' with the fabric or with
each other, while the cam prevents movement
in the other direction.
It will be understood that the locking position
in Figure 3 is only one of many positions in which
the locking function may be effected by the cam
M, which may be moved into all intermediate
positions between those shown in Figures 2 and 3
and also beyond those shown in Figure 3, and
may perform this locking function in any of
these positions. The exact position of the cam
while performing its locking function depends
, on the conformation of the clasp members and
the dimensions and con?gurations of the parts
that they embrace. It will be observed that
in the locking position shown by way of example
in Figure 3, the ears 26 are at approximately
right angles to their position as shown in Fig
ure 2, in which latter position the cam performs
no locking function.
It will be seen that one of the outstanding
advantages of a clasp constructed according to
my invention is that the locking function may
. take place in a large number of relative posi
tions of the ornamental and the clasping por
tions, so that it is adaptable for use on fabrics
or other materials of a thickness varying be
tween wide limits, instead of being restricted,
as many such devices are, to a few locking posi
tions, whereby such a device attains its maximum
Having thus described my invention, and illus
trated its use, that which I claim as new and
desire to secure by Letters Patent is-—
