cam-heads o. The cam-heads o and shanks
rn' are respectively inserted through perfora-
tions in the front plate 10 in a plane defined
by the section-line 4 4 in Fig. 2, and the cy-
5 lindrical heads n, that are peripherally
roughened, loosely contact with the outer
surface of said front plate. The cam-heads
o, which are formed or secured upon the in-
ner ends of the shanks in', are preferably
10 segmental, each having a portion removed,
and the portion that remains is rendered con-
vex on its peripheral edge. The latch-bar
17 is of such thickness and width in its end
portions that the rear edge of the upper
15 member having the hook h thereon will be
opposite the upper cam-head o and have
clearance therefrom, so that the hook h will
be out of engagement with the hook-nose e
on the shackle-bow when the cam-head is
20 turned so that the flat side thereof is oppo-
site the rear side edge of the latch-bar, as is
shown in Fig. 3.
A plate-spring 18 is secured by one end
upon the .casing of the locket and is so bent
25 that the free end has engagement with and
normally presses upon the edge of the limb
17a that is farthest from the lower cam-
head o, thus enforcing contact of the upper
and lower members of the latch-bar 17 upon
30 the cam-heads o.
The relative position of described parts'is
such that upon turning the cam-heads o so
as to cause their convex surfaces to impinge
upon adjacent edge portions of the latch-bar
35 17 the hook h will be forced into locking en-
gagement with the hook-nose e of the shackle-
bow 15, if the latter is closed, a reversed ro-
tatable movement of the heads n serving to
dispose the flat sides of the cam blocks or
40 heads o near the corresponding edges of the
latch-bar 17, thus permitting the spring 18
to retract the hook h by pressure on the limb
17a, as shown in Fig. 3.
Upon the inner surface of the lid or back
45 wall 1.2, near the corner thereon that is ad-
jacent to the opening c' in the casing side
wall when the lid is closed, a locking-lip 19 is
secured, and, as shown, consists of a bent
plate-like finger that lies in contact with the
5o inner surface of the front wall 10 at the open-
ing c' when the lid 12 is closed. The locking-
lip 19 in its portion that contacts with the
inner surface of the front wall 10 when the lid
12 is closed has such thickness as will adapt
55 the hook-nose e on the shackle-bow 15 to
slide down past the lip when said nose is in-
serted into the casing through the opening
c', this insertion obviously adapting the nose
e to hold the lid 12 in closed adjustment.
6o Upon the partition 14 at its side nearest to
the lid 12 a miniature likeness may be se-
cured, and another likeness be affixed uponthe inner surface of the lid. It will also be
seen that a shallow chamber r is formed be-
tween the lid and partition, wherein a lock of 65
hair or the like may be held when the lid is
closed and locked in that condition.
It will be seen in Fig. 1 that a circular row
of spaced indicating-marks s is placed on the
front surface of the front wall 10 around 70
each head n,, these graduations having spaced
numerals or other indicating characters
thereat, and upon each head an index-notch
is formed. The index-notches are so rela-
tively positioned that they will respectively 75
be disposed oppositely a certain scale-mark
s when the hook h is released from the hook-
nose e by a rotatable adjustment of the heads
n, which adjustment if not exact will fail to
release the shackle-bow, and of course the 8o
lid 12 will remain in a locked condition until
the proper combination has been effected by
rotatable adjustment of the heads n. There
may be other heads or knobs p, secured on
the outer surface of the front wall 10 for or- 85
namental effect, and all the heads n p may be
set with jewels s' to enhance the value and
ornate appearance of the locket, which may
be formed of precious metal or be plated
with such metal to give it an ornamental ap- 90
pearance.
Having thus described my invention, I
claim as new and desire to secure by Letters
Patent-
1. A permutation locking device for lock- 95
ets comprising a casing having a front wall, a
rim thereon, and a lid hinged upon the rear
edge of the rim, a shackle-bow having a hook-
nose on one end that enters the casing, said
bow being hinged at the opposite end in the roo
casing, a pivoted latch-bar having a hook on
one end that interlocks with the hook-nose
when the shackle-bar is closed and the hook
on the latch-bar is rocked toward said hook-
nose, a locking-lip on the lid held by the hook, r05
nose when the lid and shackle-bow are closed
means for rocking the latch-bar to lock the
lid and shackle - how, rotatable releasing
means, operative from the exterior of the
front wall, and graduations on said front 110
wall which indicate the release of the lid and
shackle-bow.
2. A permutation locking device for lock-
ets comprising a casing having a rim, a front
thereon and a rear lid hinges on the rim, a 115
shackle-bow held to rock on the casing at one
end, and having a hook-nose on the other end
that enters the casing when the shackle-bow
is closed, a latch-bar held to rock in the cas-
ing and having a hook on one end that may 20
engage the hook-nose, a locking-lip on the lid,
held by the hook - nose when the lid and
shackle - bow are closed, a spring pressing
upon the latch-bar and retracting the hook!93
