The reference numeral l indicates a bank lobby
and 2 designates a counter extending along one
side of the lobby, there being a cellar or basement
3 beneath the lobby and a .doorway 4 affording
entrance to the lobby. Tracks 5 are set inthe
walls at the sides of the doorway and a vertically
movable door 6 is slidably ?tted to these .tracks,
said door consisting of a frame ‘I and rods or bars
8 secured rigidly in and extending between the
top and bottom of the frame. The door is nor

support, as a wall or column in the cellar, and it
will Joe-noted that the pivot is .near one end of
the latch, the short end of the latch engaging over
the projection ill and being beveled 0r tapered on
its upper side to provide acam to permitthe pro
jectio-n to ride‘ easily thereover when the door is
descending. The latch is yieldably held in its
active position by a contractilespringlz suitably
50 anchored atone end andhaving its opposite end
connected With-the latch by a cable l3 which is
secured upon, theouter side of the latch or latch
arm, as at l3’. Pivoted between its ends upon
the-bracket H is anuprightkeeper M, the lower
end of whichrforms aihook :15 engageable under
der a pulley 22 on‘ the adjacent wall, and then up
to and over a pulley 23 on the cellar ceiling. From 15
the pulley 23, the cable is carried to a treadle 24
arranged back of the counter where it may be
easily operated by a teller or other employee. The
treadle is shown in detail in Figure 4 and com
prises a stem slidably mounted in and extending
through the ?oor of the banking room, a spring
25 between the ?oor and the head of the treadle
yieldably holding the treadle raised and a suit
able stop 26 on the treadle below the ?oor limiting
the upward movement. A bell crank lever 21 is
mounted adjacent the treadle and has one end
attached to the cable 20, the opposite end of the
lever being formed with a slot 28 receiving a pin
or stud 29 on the treadle.
It will now be under
stood that if the treadle be depressed, the bell 30
crank lever will be rocked to exert a pull through
the cable 20 to rock the keeper out of engagement
with the latch whereupon the door will be free
to rise.
A weighted means including a platform 29’ 35
carrying weights 730 is mounted for slidable move
ment on a pair of upright guide posts 3|, and a
cable 32 connects the platform with the lower
end of the door 6, the cable 32 being secured to
the door through the medium of an eyed member 40
32' shown in Figure 5, and ‘the intermediate por
tion of the cable is trained about suitable ‘pulleys,
with the result it will be seen that when the door
is lowered, the weighted means will be suspended
near the ceiling as shown by dotted lines in Fig
ure 1. The platform has secured thereto and
rising therefrom a pair of sleeves 3-0’ that are
threaded on the uprights to act as guiding means '
{for the platform and the weights 30 have recessed
sides to receive the sleeves therein, as‘ shown in 50
Figure 1. When the latch is released, the weighted
means will drop, as shown in full lines in Figure
l, and the door will be pulled up to close the door
way 4. The latch will yield to the upward move
merit of the door, thus increasing the tension of

Generally, there is a table or desk 33 in the
bank lobby for the use of a watchman or other
attendant. We provide a treadle34 under this
15 table which is connected to one end of a~lever
35 suitably fulcrumed between its ends on the
cellar ceiling and having its oppositeend at
tached to a branch cable 36 which is united with
the cable 2!] so that depression of the treadle-34
will cause the same action as depression of the
Formed on the side edge of the door, at its lower
end, are downwardly pointing ratchet teeth 31,
and a pawl 38 is arranged adjacent the door near
the ceiling of the basement to engage the teeth
and lock the door in its raised position. The pawl
is pivoted at its lower end and inclines toward
the door so that the teeth may ride under the
pawl which will automatically drop under the
ratchet teeth, being pressed thereto by a spring
39 arranged in any suitable convenient manner.
Between the pawl and the door is a crank arm
40 on the inner end of a rock shaft 4| which may
It will be noted that the latch 58 is disposed
nearly vertically and is pivoted near its lower end,
its lower shorter arm being engaged with the 10
catch 51 and a spring 59 acting to maintain the
engagement between the latch and the catch.
The latch is pivoted upon a bracket or panel 60
and the spring is disposed above the panel and
connected with the latch by a cable 6| as at 6|’.
A keeper 62 is pivoted between its ends upon the
panel 60 above the latch and has its end adjacent
the latch formed with a hook or shoulder 63 to
be engaged by the upper end of the latch which
will be thereby held against rocking. The keeper
is also provided with an eye 64 at its shouldered
end to which a cable 65 is attached so that if a
pull be given the cable, the keeper will be lifted
out of engagement with the latch and the weight‘
54 will at once act, the upward movement of the 25
keeper being limited by stop pins 66, 61 on the
panel above the keeper. The cable 65 extends up
from the keeper to and over a pulley 68 and to a
trip lever 69 to which it is connected by a spring
10, as shown. The trip lever is pivoted between 30
its ends within an opening ‘H in the wall of the
main doorway, and it will be readily noted that
both arms of the lever are curved. The free end

ing, the side of the crank arm 46 bearing against
the side of the pawl and a second crank arm 42
being provided on the outer end of the shaft.
When force is applied to the crank 42 to rock the
shaft, the crank 40 will be rocked against the
pawl to swing the latter out of engagement with
the door, thereby permitting the door to be pushed
down to its lowered position. ' A cable 43 is at
tached to the crank 42 and extends therefrom
to a crank 44 on the bolt or tumbler of a locking
mechanism 45, the key to which is to be held by
the police force or other authorities. The locking
mechanism may be of any approved design and
is illustrated in a conventional manner only. As
50 shown in Figure 2, the locking vmechanism is dis
posed in a compartment 46 at one side of the
main doorway 4 and the entrance to this com
partment is to be controlled by the police.
A horizontally movable door 41 is arranged to
roll across the doorway 4 at the outer side of' the
door 6, said door 41 consisting of bars 48, movable
through guide openings provided therefor in the
wall of the doorway 4, and a post 49 connecting
upper limit of its movement, its side edge will ride
over the free end of- the trip lever and rock the
lever to pull upon the cable 65 thereby lifting
the latch as described, whereupon the door 41
will be projected across the door opening.
To the end of the keeper 62 remote from the
cable 65 is attached a cable 12 which'is held taut
by a spring 13 above it, and attached to and

er are cables 74 which pass around suitable guide
pulleys to treadles 15 located at convenient or
strategic points in the banking room and corre
sponding in all essential respects to the previously
described treadle 24. By depressing a treadle 15,
the horizontal door may be operated to close the
main doorway, even though the vertical door
should fail, but generally the vertical door will
operate and will automaticallyset the horizontal
door in motion.
The door 41 has rearwardly projecting ratchet
teeth 16 on its upper edge and a pawl 11 is pivot
ally mounted above the door to drop into engage
ment with one of the teeth when the door is closed
to thereby lock the door closed. The bolt of the
lock 45 is provided with a crank arm 18 at its 60
the inner ends of the bars and equipped with a
roller 50 at its lower end to facilitate its travel.
A cable 5| is attached to the post 49 and extends inner end and a pin 19 on said crank arm extends
therefrom longitudinally of the door to a pulley ' under the pawl 11 so that when the lock is opened
52 on the wall of the compartment 46, then the pawl 11 will be rocked up out of engage
