1 Claim. (Cl. 'l0-456)
This invention relates to improvements in key
The invention is particularly directed to struc- I
tural features of improvement in a key case of
5 the type wherein the key holders are mounted
in such a way that they may be conveniently re
moved and replaced, when desired. An example
of this type of key case will be found in United
States Letters Patent No. 1,908,846, granted May
10 16, 1933, on an invention of Carleton H. Howe.
In the key case of such patent, the key holders
are held against removal from their supporting
member by a reciprocable locking device which
can be manually moved against the opposing
15 force of a spring to a position wherein the key
holders, or. any one thereof, may be removed from
the supporting member.
In this type of key case, the’ spring is relied on
to retain the reciprocable device in locking posi
tion. Removal of the spring from the case is pos
20 sible and accidental loss of the spring can and
has in some instances occurred. Without the
spring, the locking device loses all of its effective
ness in insuring against loss of keys from the case.
Thus, even though the locking device has been
carefully designed to function effectively to pre
vent loss of keys, its effectiveness depends wholly
on the spring. Without the spring the key case
cannot function and is useless.
This invention has for its object to provide in
a key case of the class described, a means for
positively retaining the spring of the locking de
.vice in the key case against loss or removal, there
by providing added insurance against loss of keys
35 from the case and a substantially fool-proof con
Other objects will appear as the detailed de
scription proceeds and will be pointed out in the
appended claim.
The invention will be disclosed for illustrativel
purposes in connection with reference to the ac
companying drawing, in which:

In the drawing, I have shown my invention in
connection with a key case of the type disclosed 10
in the above named patent. This case includes
a suitable folder of leather or the like, usually
having a central section I0 and two iiaps I I, fold
able in overlapping relation over the central sec
tion and capable of being held in such relation by
interengageable snap fastener elements I2 and I3.
Secured to the central section IIJ, as by rivets
I4, is a plate I5 of thin metal having its upper
edge portion rolled over as shown to provide a
hollow and partly cylindrical portion I6.
key holders I'I, which may be of the form shown
in the United States Letters Patent No. 1,968,989,
granted August 7, 1934 on an invention of Warner
R. Buxton, are provided with ball heads I8 which
are mounted in the hollow portion I6 and en 25
able the key holders to swivel as well as swing.
The portion I6 has transverse slots I9 therein,
one for each key holder. Each slot has a width
such as to freely receive the neck portion 20 of
the key holder and of such length as to enable 30
the key holder to swing from its normal pendant
position upwardly through an angle of about 180
degrees. Each slot at its upper end terminates
with an enlarged portion 2l of a size and shape
such as to enable the ball head I8 to pass there 35
through. Normally,> these enlargements are
closed by the parts 22 of a locking device 23,
which is mounted on the plate I5 to slide in the
direction of the axis of tubular portion I6 from
the position shown in Fig. 6 to that shown in 40
Fig. 7. When the device 231s positioned as shown
in Fig'. '7, recesses 24, provided in the upper edge
of device 23, register one with each of the en
largements 2l and enable the key holders to be
removed by withdrawing the ball heads I8 there 45
The locking device 23 is mounted in the same
general manner disclosed in the above-named
Howe patent. It has a part 25 which extends
into a slot 25 formed in the lower wall of the 50
tubular portion I'B and is held between the plate
I5 and the long side wall of slot 26. This portion
25 has shoulders 21 one at each end thereof,
which by abutment with the end walls of slot
26 limit the extent of sliding movement of the 55
device 23. A spring 28 tends to hold the lock
ing device in the position shown in Fig. 6 and the
right hand shoulder 21 then abuts the right hand
end of slot 26, as shown in Fig. 4. To move the
locking device from the position shown in Fig.
6 to that shown in Fig. 7, a ñnger piece 28 is pro
rounded wall of tubular portion I6 as a pivot.
The part 25 is thus swung into slot 26 and the
right hand shoulder 21 thereof is moved against
the. right hand end of slot 26. The device 23
vided on one end of the device, of the form shown
may be held thus positioned with the thumb' of '
in Fig. 5. The linger piece is bent forwardly at
right angles to the device 23 and the upper part
the left hand. The spring 28 is then slid-in place
on finger 38. Then with the thumb of the right
hand the operator compresses the spring and at
10 thereof serves to close the left hand end of tu
bular member I6 and the lower part extends be
low the member I6 so that it may be conveniently
moved with the thumb nail. This finger piece
is set ñush into the end of the tubular member
15 I6 and does not project beyond such end as in
said Howe patent. This arrangement furnishes
additional protection against accidental opera
tion of the locking device and the lower portion
of the finger piece is made small and located be
20 low portion I6 and against plate I5 for similar
outwardly away from the plate, the rounded inner
part of the device 23 engaging the upper rear
the same time pushes downwardly on it to carry
the finger between the lugs 3|. The finger piece
28 seryes to prevent the spring 28 from moving
the locking device 23 to the right and holds it
properly positioned, while the portion I6 is com
pletely rolled down into final form to hold the
locking device in position.
The operation of the key case is the usual one
and is fully disclosed in the above named Howe
The invention, by preventing removal and par
ticularly accidental loss of the spring of the lock
The locking device 23 has an extension from the
part 25 in the form of a narrow finger 38 the sides
of which parallel the axis of the tubular portion
25 I6 and are so spaced as to freely fit inside the
spring 28. The spring seats at one end against
the shoulder formed at the intersection of the
ers. Even if the key holders are not often lost,
the escape of the spring from its position between
ñnger 30 with the part 25. At the other end, the
spring seats against two lugs 3l which are struck
its seats in the key case structure of said Howe
patent, causes the user a great deal of annoyance.
30 up from the left hand end wall of a recess 32,
formed in plate I5 in underlying relation with
spring 28 to provide clearance thereof. The
finger 30 is long enough to span this recess 32
and extend beyond the same far enough to have
35 its free end received between the lugs 3I which
are spaced apart for vthis purpose. Thus, the
spring 28 is, at all positions of the locking device,
held on the finger 30. The only'way in which
the spring can be removed is to remove the finger
40 from between the lugs and this requires bending
up of the ñnger from the device 23 or removal of
the device from plate I5. Removal of the de
vice from plate I5 means bending out the lower
wall of tubular portion I6 from plate I5 and,
45 since both the portion I6 and ñnger 38 are
made of stiif metal, the bending operations neces
sary to release spring 28 are not easily accom
plished, much less are they likely to be effected
accidentally which is whaty the invention seeks
to prevent.
The locking device and its spring are assem
bled before the tubular portion I6 of the plate is
completely formed. With the plate I5 in the
form shown in Fig. 9, the device 23 may readily be
55 slid into place. Then the part 25 thereof is swung
ing device, makes the structure substantially fool
proof and affords added insurance against loss of
keys caused by accidental escape of the key hold 25
The spring, if it escapes, is liable to pop out 30
and move a considerable distance and, being
small, is often diilicult to find. Unless the spring
is found and replaced, the key case is useless
because, as has been described, the spring is the
means which holds the locking device in locking 35
position. The invention saves the user from
annoyances, such as described, and insures that
the locking device will be held in place at all
times except those when it is intentionally re
What I claim is:
-In a key case, a support for a key holder hav
ing an opening through which the key holder may
be removed, a device shiftable from one position
to another to 'cover and uncover, respectively,
said opening, a coil spring for retaining Ísaid
device in one of said positions, seats one for each
end of said- spring and provided one on saidrsup- i
port and one on said device, one seat comprising
a pair of spaced lugs, and an extension from the 50
other seat passing entirely through the spring
and between said lugs and overlapping said lugs
in all positions throughout therange of movement
of said device.
