17 Claims. (Cl. ’l0-269)
This invention` relates to a timlelock of the type
adapted to prevent access to a structure.
As is Well known by those skilled in the art,
timelocks are adapted to place structures beyond
VI! human control for certain definite periods of
time.
Thus, a banker having- a timelock on his
safe, is` able in the late afternoon, to set that
timelo’ck to open the safe ín the morning. Once
he closes the door of the safe, it is impossible for
10 anyone to open the safe until the following morn
ing when the time movements run down and op
erate the mechanism in a predetermined manner
well understood by those skilled in this art. Dur
ing the period of protection, should the banker
r be directed to open the safe, he is powerless to do
so. Robbers know this and do not even attempt
for which the regular movement is set, so as to
set up a delayed time period beyond the regular
time period.
My invention makes it possible therefore, to ob
tain a period of time protection beyond the nor
mal protection effective during the night opera
tion of the regular time movement. In mïy in
vention, I utilize the operation of a regular time
movement to release certain mechanism at the
end of the period for which it is set. I then have "i
a. special time movement which must be released
by the said ñrst movement and by a predeter
mined additional operation from the outside of
the safe. This special time movement must then
run for a further predetermined period, generally
ñfteen minutes, before the safe may be opened.
night robberies.
In this way, I am able to forestall early morn
One of the objectionable features of a timelock
of this type is that the safe is automatically
opened or relieved from time protection in the
morning. Thereafter, anyone may open the safe
and obtain access to its contents. In those safes
ing attacks by robbers who know when the run
ning of the regular time movement terminates,
which have in addition combination locks, a rob
ber may force the banker to operate the combina
tion upon the expiration of the time protection
operation on the outside of the safe. Since this
additional operation on the outside of the safe
may take place early in the morning, or possibly
late in the morning, or sometime late in the after
noon, depending upon the conduct of the bank,
it is readily seen that the early morning robber
period.
In recent years, due to the knowledge by rob
bers of this weakness of time locks, the early
morning holdup has' nourished. I'I‘he robbers de
30 termine just when the regular time movements
' are set to run down, which is naturally just be
fore the opening of the bank for regular business.
The banker must be prepared for the possibility
of a heavy demand on him early in the morning,
35 and must set his time lock accordingly even
though he does not intend to open the safe at the
time for which the opening is set. As a matter
of fact, it is sometimes not necessary for the
banker to open the time protected safe until late
40 in the morning, and sometimes not- until late in
the afternoon, depending upon` the amount of
business which is done. The robbers, having laid
their plans, come in early in the morning, hold up
the Watchman, and as each employee enters the
45 bank, they take him under guard and then when
the time movements have run down, they force
the employee having the combination to open the
safe. This opening takes place just before busi
ness hours, the money is obtained, and the rob
’ bers escape.
In my invention, a further running
of a special time movement is necessary after the
running of the regular time movement, and the
running of this special time movement may be
started only upon manipulation of means outside
55 the safe and after the running of the full period
since even after the running of the regular time _
movement, there must be a further wait which
begins only after the predetermined additional
is seriously handicapped. He is always faced
with an enforced waiting period of fifteen min
utes or more.
This wait of fifteen minutes is
exceedingly important and forestalls the opera
tion of the early morning type of holdup.
More in detail, my invention utilizes a series of
three time movements, one of which is set to re
tract the regular detent mechanism of the time
lock after a relatively long period. This move
ment is an emergency movement and is intended
to operate only in case the regular retracting
movement fails to operate as intended.
40
'I'here is a special movement which has contact
with a detent retracting bar and which is adapted
to retract that bar within a short period of time,
usually fifteen minutes, although it may be set
for thirty minutes, or forty-five minutes, as the
case may be. This special movement is normally
maintained wound and stationary by two mecha
nisms, which may be interlocked or independent,
and which may assume many forms.
45
One of
these mechanisms is adapted, preferably but not 50
necessarily, to be moved to movement starting
position upon the operation of the detent con
trolled safe bolt in a retracting direction.
The special movement is also controlled by a
mechanism under the control of a third and regu

lar operating time movement. This regular
movement is the type of movement normally used
in a timelock for moving the bolt obstructing
detent from obstructing position after a predeter
mined period of time. Instead of using this
movement to move the bolt obstructing detent aS
is usual in the art, I utilize it for controlling the
running of the special movement. Thus, the
control mechanism for the special movement is
10 operated by this regular movement after a. period
of time, so as to start the running of the» special
movement to retract the bolt obstructing detent.
While for convenience the two control mecha
nisms for the special movement are shown and
15 described in particular relation to one another,
those skilled in the art will appreciate that many
variations in their relationship may be made
guided by a screw 21 and by further means which
need not be shown here. On the arm 49a of
the detent i9 there is mounted the sliding piece
28 which is adapted to Contact the portion 25
through screw 25d` and move the same against the
arm 2li to move the lever 2 i, and thus move spring
22 into movement releasing and starting posi

In my patent, No. 1,858,964, I show a similar
operation of a lever i@ by a slide piece 2li actuated
by retraction of a bolt 3. Reference should be
made to this patent for a detailed description 15
of the operation of the parts indicated and for a
clearer indication of their function.

are shown in phantom in dotted lines. Fig. 3 is a

and starting of the special movement. Fig. ¿i is

Referring now more particularly to the draw
ing, reference numeral i6 indicates the casing
35 of a regular type of time lock mechanism well
known in this art, while reference numeral il
indicates the cover for this. casing. A retracting
bar i2 is adapted to be moved in a right hand
direction by a pin i3 carried on the dial I4 of
40 special movement C and by a pin i5 on dial i6
of the emergency movement A. The emergency
movement A is generally set for about seventy
two hours or perhaps forty-eight hours and actu
ates the bar l2 only under unusual circum
45 stances, such as the stopping of the special'move
ment C.
The operation` of the bar IZ is adapted, through
the lever arm il' and arm i3 illustrated in Fig. 2,
to operate the bolt obstructing detent i9 against

viewing Fig. 2 that the winding post 3G is fixed to
a disc Si which carries a pin 32 which is oper 25
ated by a plate 33 ñxed for integral movement
with the bolt 29 rthrough the intermediary of
the member 3d. Thus, upon retracting move
ment of the bolt 2S, the plate 33 will contact the
pin 32 to wind the movement in the direction of 30
the arrow shown in Fig. 2. At the same time, a
gear pinion 35 also carried by the winding post
Sil asshown in Fig. 1, operates to move the dial
M through its teeth 36 in a manner which is
common in this art. The teeth 36, however, co
operate with a pinion 3l' which is in frictional en
gagement with the shaft- 3S on which the arm
2d and the lever 2i are supported. Thus, the
movement of the dial lli will act to rotate the
pinion 3l and the friction between pinion 3l
and the shaft 38 moves the lever Z! into move
ment stopping position. A more detailed descrip
tion of this mechanism is presented in my Patent
No. 1,962,933 supra, in which this same mecha
nism is claimed. Thereafter, a setting of the
combination mechanism and an attempted re
traction of the bolt 29 will act to release the
movement from spring 22 on lever 2l as has

already been indicated.

ment will be held in stopped position, due to the
cooperation of the levers 2l and 4B and their
springs 22 and 43, respectively, with the balance
wheel 23. In the morning, at the time set, the
regular movement will have run down and the
bolt 29, the special movement will be released
to move the bolt obstructing detent I9 from ob

for which it is set.

Thus, after the running of the regular move

time protection, and is always protected by a
delayed period until a further manual operation
has taken place.
As I have indicated already, it is possible to

special movement C, and for obtaining the re
sults indicated. I believe my contribution to
the art to be of such nature that I am entitled
to a broad interpretation of the claims appended
hereto.
