DOOR OPERATING AND‘ LOOKING
MECHANISM
Anthony Schneider, Silverton, Ohio
Application November 13, 1936, Serial No. 110,719
7 Claims. (Cl. 189-7)
This invention relates to control means for a
door whereby the door may be closed and secured,
from a remote location, and thereafter auto
matically released upon the expiration of a pre
determined time interval. The invention is thus
applicable for use in connection with banks, jails,
etc.
An object of the invention is to provide novel
means for actuation, securement, and release of
10 the door, and as will appear, a particular object
is to provide for closure of the controlled doorway
notwithstanding blocking of the normal closing
path of the door.
The exact nature of the invention together with
' further objects and advantages thereof will be
apparent from the following description taken in
connection with the accompanying drawings, in
which Figs. 1 and 2 are views in elevation from
the front and rear respectively, of a swinging or
20 hinged type of door in which the invention is
and Fig. 8 is a detail in sectional elevation as in
the plane of line 8-8, Fig. 2.
55
one or more projections 5, three being indicated,
and for each projection a plunger 6 is mounted in
a bracket 1. For each plunger 5 an actuating
screw 8 is rotatably mounted in the bracket 1,
having threaded relation with the plunger. Co

line 3-3, Fig. 2; Figs. 4 and 5 are views corre
of line 6—-6,, Figs. 3 and 4; Fig. '7 is a diagram

Power means are provided for so closing the
door part lw, shearing the pins 4 if necessary.
For the purpose the door part la is provided with 15
to the lowermost screw 8.
matic view showing the door-controlling circuit;
With reference now to the drawings, the door
shown is mounted for swinging movement be
tween open and closed position to control its doorway, and comprises two parts la and lb, of which
the part la is hinged as at 2 at a side of the door
way. This part la may be of grille type and is so
proportioned with respect to the doorway that in
closed position its free edge will provide a clear
ance from the corresponding side of the doorway
and extending to the bottom of the doorway, of
substantial width but insufficient to permit pas‘
sage of a person therethrough. The other door
part lb: is mounted for normal movement to~
gether with the ?rst door part as a unit, but is
capable under emergency conditions, of move—
ment independent of the ?rst door part. The
second door part which may be solid, is cooper
ative with the ?rst door part for complete closure
of the doorway when in closed position. As here
shown the second door part is hingedly mounted
upon the ?rst door part as at 3 so that it may have
or
From the arrangement described it will be ap
parent that should sufficient force be applied to
the door part la to close the door, notwithstand
ing such obstruction to the door part lb as indi 0
cated at A, Fig. 5, the pins 4 will be sheared and
the doorway effectively barred.
incident drive of all the screws 8 is provided as
by a chain 9 running over sprockets l0, one for
each plunger. For drive of the screws, a motor
where the door is blocked as indicated in broken
30 lines; Fig. 6 is a sectional detail as in the plane
45
as by one or more shear pins 4 replaceably mount
ed as indicated in Fig. 8.
embodied, the door being in closed position and
parts in Fig. 2 appearing in section to show de
tails of construction, the latter View showing also
the door-actuating mechanism; Fig. 3 is a typical
sponding with Fig. 3 but showing the door in Fig.
4 in open position and in Fig. 5 With its parts as

independent swinging motion about an axis ad
jacent the axis 2 as indicated in Fig. 5. To
cause the two door parts to normally move to
gether, a breakable connection is provided such
ll is provided connected by suitable gearing l2
25
It will be apparent that by the arrangement de
scribed and commencing with the door open as in
Fig. 4, operation of the motor in the proper direc
tion to extend the plungers 6, will cause the latter
to engage their projections 5 upon the door with a
camming action and will force the door to the
closed position of Fig. 3, breaking the shear pins
4 if the door part lb be obstructed as in Fig. 5.
The door being thus closed, it is so secured by the
irreversible nature of the drive provided by the 35
screws: 8, but upon reverse operation of the motor
ll to withdraw the plungers 6, the door may be
opened in the usual manner.
A control circuit for the motor ll may be pro~
vided as indicated in Fig. '7, wherein power is had
from the lines L1, L2 and L3. l3 and I4 are three
pole switches, one for each operating direction of
the motor ll. l5 and H are switches arranged
to be thrown by a projection l8 on one of the
plungers 6 as the latter attains the end of a 45
stroke. Thus when the plungers are in the open
position as in Fig. 4, the switches l6 and H are
positioned as in Fig. 7, as the plungers advance
in door-closing direction the switch l6 auto
matically closes, and as the plungers attain the
door-closed position of Figs. 3 and 5, the switch
H which is a double-throw switch, is automat
ically thrown from the position indicated in Fig.
7 to its opposite position.
I9 is a‘ double-throw relay switch controlling
2
2,113,966
the main switches l3 and I4 through their actu~
ating coils |3a and Ma respectively. 20 is an
automatic timing switch controlled by a cam
2| driven by a timing motor 22. 23 is a bell or
other signal device arranged to be energized when
the door is closed by the motor II, and 24 is a
switch by which door-closing by the motor II is
initiated and which may be located remotely from
the door.
Operation for power-closing of the door will
10
be as follows, commencing with the parts posi
tioned as in, Figs. 4 and '7.
Instant depression of the switch 24 completes
a circuit including the coil |3a of the switch l3
15 and starts the motor || operating in closing di
rection to throw the plungers 6. It also throws
the switch l9 to its opposite position from that
shown, which establishes a maintaining circuit
for the coil | 3d and starts operation of the signal
20 device 23 through a circuit including the switch
|‘|. As the projection I8 leaves the switch Hi, the
latter closes. As the plungers complete their
door-closing movement, the projection I8 throws
the switch H which de-energizes the coil |3a
opening the switch | 3 and stopping the motor I |,
and at the same time completes a circuit ener
gizing the timing motor 22 to drive the cam 2|
and de-energize the signal device 23. As the
switch I3 opens, the switch l9 returns to its initial
30 position. This cam and its drive is so arranged
that after a predetermined desired time, say ten
minutes, has elapsed, the cam 2| throws the
switch 20, opening the circuit of the timing motor
22 and stopping this motor, and completing the
circuit for the coil Ma of the reversing switch
It of the motor ||, this circuit including the
switch |6 now closed and the switch | 9.
The
plungers 6 are thus withdrawn by the motor II,
the switch H being permitted to- return to its
original position by the projection l8.
As the plungers attain their initial open posi
tion the switch i6 is opened by the projection I8,
tie-energizing the coil Ma and stopping the
motor ||.
4.5
The cycle of operations is thus completed, the
door is. free to be reopened, and upon resetting of
the timer cam 2| to return the switch 20 to its
shown position the parts are preset for initiation
of another closing cycle by depression of the
'50 switch 24.
Should the door he already closed when the
switch 24 is thrown to initiate the closing cycle,
it will be apparent that the power apparatus will
merely secure it against opening during the timed
55 period described.
Obviously when the power closing apparatus
is in its usual open position as in Fig. 5, the door
may be opened and closed by hand in the usual
manner and it may be provided with an ordinary
60 key-operated look as indicated in Fig. 1 for its
normal securement in closed position.
