LOCKING
MECHANISM
FOR
BUILDING
STRUCTURES
Steve J. Hodos, San Francisco, Calif.
Application March 3, 1937, Serial No. 128,762
3 Claims. (Cl. 292-33)
This invention relates broadly to improvements
in locking mechanism for’ building structures and
has particular reference to a combined motor
operated and manually operated locking means
5 which functions to lock the doors of banks and
like places wherein considerable cash is kept on
hand to prevent the escape of burglars who enter
these structures with intent to burglarize the
same.
’
The principal object of the invention is to pro
vide a locking mechanism for bank doors and
like structures which may be either remotely con
trolled by a motor operating mechanism or that
may be manually controlled within the struc
ture.
Another object of the invention is to provide
a combined motor controlled lock of the class
described that will instantly lock either double
or single swinging doors from a concealed point
20 preferably in the ?oor below the door or doors.
A further object of the invention is to provide
a locking mechanism of this type that may be
operated from an enclosure such as an adjoin
ing vault or it may be remotely controlled from
CA either the inside or the outside of the structure.
A still further object of the invention is to pro
vide a locking mechanism of the class set forth
that is positive in operation, is comparatively
simple in construction and that may be installed
b: O in any structure.
Other objects and advantages of the invention
will become apparent with reference to the sub
joined speci?cation and the accompanying draw
ing in which:---

Figure 1 is a sectional diagram of my improved
locking mechanism as it would appear installed
in a' banking or other structure and showing the
operating motor and manual control arranged
in a vault within the structure;
Figure 2 is an enlarged sectional detail showing
110
one of the cam operated locks in locked position
beneath one of the doors of the structure; and
Figure 3 is a transverse section of the same
, taken on the line 3-3 of Figure 2.
In banking and like structures employing my
system wherein swinging doors are utilized and
a burglar enters these swinging doors, said doors
may be readily locked so that when he once enters
the structure he is imprisoned therein until the
oi?cers arrive.
This system includes swinging doors 5 and 6
hinged in the structure ‘i in the usual manner,
as shown in Figure 1. These doors are provided
with ?xed cam members 8 and 9 arranged cen
trally thereof and under the bottom edges, as
clearly disclosed in Figure 3.
The cams 8 and 9 are convex and are positioned
in slots l0 formed in the floor H and mating
locking cams l2 and i3 are arranged upon rods
14 and I5, said cams l2 and I3 being ?xed to the
rod l4. These cams l2 and I3 being concave
and arranged to move laterally of the cams 8
and 9 from central neutral positions to locking
position which locking position is shown in Figure 10
2. In this manner a wedging action is effected
so that the cams 8 and 9 are locked to the cams
l2 and 13 thereby locking the doors against move
ment on their hinges.
_
The mechanism for operating the cams l2 and 15
I3 thru the action of the rod l4 comprises a mem
ber 16 operated by the motor l1, pinion l8, and
rack l9 meshing with said pinion l8 so that
when the motor is energized thru the medium of
the battery 2|] and its circuit and when the switch 20
2| is closed, the rod I4 is moved to operate said
cams l2 and I3 relative to the cams 8 and 9, the
element l5 acting both as a guide and a conduit
to carry the circuit wires.
theRemotely
circuit and
located
mayswitches
be utilized
22 are
to energize
includedthe
in
motor I1 from either the inside or the outside of
the structure. Suitable bearings 23 are posi
tioned upon a sub-?oor 24 arranged under the
structure floor H and house the rod l4 and the 30
conduit 15, and conduit merely acting as a guide
and prevents turning of the rod I4 ‘and the cams
l2 and I3.
-
A manual control lever 25 is also operatively
connected to the motor shaft and may be used to 35
operate the device in case the circuits are ren
dered useless by the cutting of the wires.
In Figure 1 of the operating mechanism has
been shown enclosed in a vault 26 or other suit
able enclosure within the structure as in a bank.
I claim and desire to secure by Letters Patent
of the United States the ‘following;
1. A device of the class described comprising
means capable of being installed in a building
structure having swinging doors, comprising ?xed
cam means positioned on said swinging doors,
additional cam means cooperating therewith to
lock said doors, and motor driven means for ac
tuating said second cam means.
2. A device of the class described comprising
means capable of being installed in a building
structure having swinging doors, comprising ?xed
cam means carried by said doors and movable
cam means cooperating therewith to wedge said
?xed cam means when moved relatively thereto, 55

and motor mechanism associated with said mov
able cam means to cause said wedging action.
3. A device of the class described comprising
means capable of being installed in a building
structure having swinging doors, comprising ?xed
cam members mounted under said doors and
movable cam members associated therewith and
‘capable of Wedging said ?xed cam members
against movement to lock the doors, a motor ac
tuated means for operating said movable cam
members from neutral positions to locking posi
tion, and a remote control for said motor.
