Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to a vehicular system having vehicles
arranged in a plurality of banks and it has particular relation to
an indicator for indicating the operation of any number of such
banks.
Although the invention is applicable to vehicles of various
descriptions arranged for operation in horizontal directions,
vertical directions or in directions intermediate the horizontal
and vertical directions, it is particularly suitable for an
elevator system having a plurality of elevator cars arranged in a
plurality of banks for serving the various landings or floors of a
building and will be described as applied to such an elevator
system.
2. Description of the Prior Art
In plural bank elevator systems it has been the practice to provide
a separate panel position and motion indicator or traffic director
panel for each of the banks. This practice not only results in
substantial initial and maintenance costs but requires substantial
space.
SUMMARY
In accordance with the invention a single panel motion and position
indicator is provided to indicate the operation of a number of
banks of elevator cars in a given building. A scan system is
arranged to display consecutively and intermittently the
operational condition of each bank of cars from the single
indicator. Provision is made for overriding the scan system for the
purpose of displaying continuously the operational condition of any
of the banks. The override may be manually controlled or it may be
in response to a predetermined condition of one of the banks.
It is therefore an object of the invention to provide a plural bank
vehicular system with a single indicator for indicating the status
of any of the banks.
It is a second object of the invention to provide a system as set
forth in the preceding paragraph wherein a scan system sequentially
displays the operational condition of each of the banks.
It is a third object of the invention to provide a system as set
forth in the preceding paragraph with overriding means for
displaying continuously the operational condition of any of the
banks.
BRIEF DESCRIPTION OF THE DRAWINGS
Other objects of the invention will be apparent from the following
description taken in conjunction with the accompanying drawings in
which:
FIG. 1 is a view in front elevation of an elevator system embodying
the invention;
FIG. 2 is a view in front elevation of a panel position and motion
indicator embodying the invention;
FIGS. 3 to 6 are schematic views with circuits shown in straight
line form of a control system suitable for controlling the
indicator of FIG. 2.
DESCRIPTIONS OF THE PREFERRED EMBODIMENTS
Referring to the drawings FIG. 1 shows an elevator system having
several banks of elevator cars. Although any number of banks may be
employed it will be assumed for present purposes that three banks
VB, VB' and VB" are provided. Each of the banks may have any
desired number of vehicles or cars. For present purposes it will be
assumed that each of the banks has four elevator cars.
The banks of vehicles or cars may be of any desired construction.
However in order to simplify the presentation of the invention it
will be assumed that each of the banks is similar to that shown in
the Santini et al. U.S. Pat. No. 2,740,495. Unless otherwise stated
the conventions employed in such patent will be employed here. By
reference to the aforesaid patent it will be understood that the
vehicle bank VB has four elevator cars A, B, C and D. Each
component of the banks VB' and VB" is identified by the same
reference character employed for the bank VB with the addition of a
prime for the bank VB' and of a double prime for the bank VB". Thus
the elevator car A' of the bank VB', and the elevator car A" of the
bank VB" correspond to the elevator car A of the bank VB.
In FIG. 1 a bank VB is arranged to serve landings or floors 1 to 10
inclusive of a building. A bank VB' is arranged to serve the first
landing or floor and landings 11 to 19 inclusive of the same
building. For the bank VB' the landings or floors 2 to 10 inclusive
may constitute an express zone through which the elevator cars run
without stopping. The bank VB" is assumed to serve a first floor
and floors 20 to 28 inclusive of the same building. In this case
the floors 2 to 19 inclusive constitute an express zone through
which the cars of the bank VB" run without stopping.
In order to display the status of the elevator system a panel
position and motion indicator is provided which may form a part of
a traffic director panel TD. This panel is shown located at the
first or main floor but it is to be understood that similar
information may be provided at any other desired points such as in
a machine room. The status of each of the banks is displayed
sequentially on the panel. For example the condition of the bank VB
may be displayed for ten seconds followed by the display of the
status of the bank VB' for ten seconds and thereafter followed by
the display of the status of the bank VB" for 10 seconds. This
cycle of display may be continued indefinitely. As previously
explained, under certain conditions the panel may be arranged to
display information continuously for any one of the banks.
Referring to FIG. 2 the panel TD has three vertical rows of
numerals representing floors of the buildings. Thus the row FL
contains numerals 1 to 10 arranged in the order of the floors and
representing the floors 1 to 10 inclusive which are served by the
bank VB. The numerals in the row FL' represent the floors 1 and 11
to 19 arranged in the order of the floors and served by the bank
VB'. In this row the floors 2 to 10 inclusive constitute an express
zone which is represented by the letter X. Finally the row FL"
contains the floors represented by the numerals 1 and 20 to 28
inclusive arranged in the order of the floors and served by the
bank VB". Here the floors 2 to 19 constitute an express zone which
is represented by the letter X.
At any one time the information displayed on the panel TD is
specific to only one of these rows FL, FL' or FL". The specific row
which is effective is indicated by the lighting of one of three
lamps FL, FL' or FL" which are associated respectively with the
banks VB, VB' and VB". Each lamp if desired may be located behind a
jewel which in FIG. 2 is given the shape of an arrow pointing to
the associated row of numerals.
Lamps VL, BVL, CVL and DVL when illuminated indicate that cars A,
B, C and D of the bank VB are in service and that this bank is
being displayed on the panel TD. It will be noted that these lamps
are arranged in a horizontal row.
In an analogous manner the lamps VL', BVL', CVL' and DVL' are
arranged in a horizontal row and are illuminated only when the
associated cars of the bank VB' are in service and the operation of
this bank is being displayed on the panel TD.
In an analogous manner lamps VL", BVL", CVL" and DVL" are
illuminated when the respective cars of the bank VB" are in service
and their operation is being displayed on the panel.
The lamps VL, VL' and VL" of the A cars of the three banks are in a
vertical row which also contains car position lamps P1, PX and P2
to P10 inclusive arranged in the order of the floors. Similarly the
lamps BVL, BVL' and BVL" for the B cars of the three banks are
arranged in a vertical row which also contains position lamps BP1,
BPX and BP2 through BP10 arranged in the order of the floors. In a
third vertical row are arranged the lamps CVL, CVL' and CVL" for
the C cars and position lamps CP1, CPX and CP2 to CP10. Finally a
fourth vertical row contains the lamps DVL, DVL' and DVL" for the D
cars of the three banks together with the position lamps DP1, DPX
and DP2 to DP10 inclusive.
Horizontal and vertical lines through any illuminated car position
lamp provide the coordinates for locating any car in the building.
For example assume that the lamp P9 is illuminated. A vertical line
through this lamp indicates that the illumination represents the
position of one of the A cars of the three banks depending on which
of the lamps VL, VL' and VL" is illuminated. A horizontal line
through the same position lamp indicates that the car is at the 9th
floor, the 18th floor or the 27th floor depending on which of the
three lamps F1, F1' and F1" is illuminated. Thus if the lamps P9,
VL and F1 are illuminated the elevator car A of the bank VB is
located at the 9th floor. As a further example if the lamps P9, VL"
and F1" are illuminated the elevator car A" of the bank VB" is
located at the 27th floor. If the elevator car A' is in its express
zone and if the lamp F1' is illuminated the lamp PX also is
illuminated to indicate that such car is in its express zone. If
the lamp P1 is illuminated one of three cars associated therewith
must be at the first floor for the reason that all cars serve the
first floor.
When one of the lamps VL, VL' and VL" is illuminated one of the
direction arrows UD for up direction or DD for down direction in
the same vertical row is illuminated for the purpose of indicating
the direction for which is set the car having its lamp VL, VL' or
VL" illuminated. If the elevator car A, A' or A" is conditioned to
bypass, a bypass lamp BP will be illuminated when the lamp VL, VL'
or VL" associated with the bypassing car is also illuminated.
Direction and bypass lamps are similarly provided for the B, C and
D cars of the three banks.
A vertical row of up-floor-call registering lamps is provided for
indicating registered up floor calls. Each of these lamps UL1 to
UL9 is horizontally aligned with the appropriate one of the car
position lamps for the associated floor. Thus if the lamp UL9 is
illuminated the horizontal line passing through said lamp indicates
that an up floor call has been registered for the 9th, 18th or 27th
floor dependent on which of the lamps F1, F1' and F1" is
illuminated.
In an analogous manner lamps DL2 to DL10 inclusive arranged in a
vertical row in the order of the floors indicate when a floor call
is registered requiring service in the down direction. Thus if the
lamp DL9 is illuminated a horizontal line through this lamp
indicates that a down floor call is registered for the 9th, 18th or
27th floor dependent on which of the lamps F1, F1' and F1" is
illuminated.
For each of the banks a dispatcher may be employed for
automatically dispatching elevator cars from a predetermined floor.
Should the main dispatcher fail an auxiliary dispatcher may be
arranged to take over automatically the dispatching function for
each of the banks. For indicating failure of one or more of the
main dispatchers three lamps EL, EL' and EL" are provided. The
illumination of any one of the lamps EL, EL' and EL" indicates
failure of the main dispatcher for the associated one of the banks
VB, VB' and VB".
A lamp is provided for each of the elevator cars for the purpose of
indicating when illuminated that the associated elevator car is in
service. For example lamps VL1, VL1' and VL1" are provided
respectively for the A cars of the three banks VB, VB' and VB".
Below each of the lamps a key switch KS is located. Each of the key
switches may be operated for the purpose of placing the associated
elevator car in or out of service.
Finally, the panel TD includes a scan control SC having a
four-position knob. With the knob in the "auto-scan" position
illustrated in FIG. 2 the system is arranged to present
sequentially on the panel TD information concerning the status of
each of the banks. For example information concerning the bank VB
is displayed for a period such as 10 seconds. This is followed by a
display for a period of 10 seconds of information concerning the
bank VB'. The cycle is completed by information concerning the bank
BV" which may also be displayed for 10 seconds. This cycle may be
repeated indefinitely.
When the knob of the scan control SC is turned to a position VB the
system is arranged to show continuously on the panel TD information
concerning the bank VB. Rotation of the knob to the position VB'
arranges the system to show continuously on the panel TP
information concerning the bank VB'. Finally rotation of the knob
to the position VP" arranges the system to show continuously on the
panel TD information concerning the bank VB".
Turning now to the circuits for providing the desired operation of
the panel TD FIG. 3 shows a positive bus L1 and a negative bus L2
representing a suitable source of direct current. Three selector
relays BR, BR' and BR" are employed for selecting respectively the
banks VB, VB' and VB" for presentation on the panel TD. When the
selector relay BR is energized and picked up it closes its make
contacts BR1 to connect an auxiliary positive bus LB to the main
positive bus L1. Circuits connected between the auxiliary positive
bus LB and the common negative bus L2 then are effective for
presenting on the panel TD the status of the bank VB. In a similar
manner when the selector relay BR' picks up it closes its make
contacts BR1' to connect an auxiliary positive bus LB' to the main
positive bus L1 for the purpose of presenting the status of the
bank VB' on the panel TD. Pickup of the selector relay BR" connects
the auxiliary positive bus LB" through the make contacts BR1" to
the main positive bus L1 for the purpose of displaying the status
of the banks VB" on the panel TD.
The energization of the selector relays is controlled in part by
the scan control SC. When this control is in its "autoscan"
condition the selector relays are energized successively in
repetitive cycles through a sequencer SQ. This sequencer may be of
any construction suitable for successively energizing the selector
relays. For illustrative purposes the illustrated sequencer SQ is
of the commutator type wherein a movable contact SQ2 is rotated
about its axis at a uniform rate. Three commutator segments SQ1,
SQ1' and SQ1" are located to be engaged successively and
repetitively by the movable contact SQ2. The coil of the selector
relay BR is connected between the commutator segment SQ1 and the
negative bus L2. Similarly the selector relays BR' and BR" have
their coils connected respectively between the commutator segments
SQ1' and SQ1" and the negative bus L2. During each revolution of
the movable contact SQ2 the coils of the three relays are
successively connected for energization across the buses L1 and L2
through the scan control SC, break contacts ME1 of a master relay
ME and a switch 401.
Under certain conditions it may be desirable to display the status
of certain of the banks for periods longer than those employed for
the remainder of the banks. For example if a down peak occurs on
the bank VB' during a period in which the banks VB and VB" are
subjected to relatively light traffic the system may be arranged to
display the status of the bank VB' for longer periods of time. To
this end the switch 401 may be manually opened and a switch 403 may
be manually closed to replace the sequencer SQ by a sequencer SQA.
The sequencer SQA is similar to the sequencer SQ except for the
dimensions of the three commutator segments. By inspection of FIG.
3 it will be noted that the sequencer SQA is arranged to display
the status of the bank VB' for a longer period during each
revolution of the movable contact.
Although the switches 401 and 403 may be manually operated, if the
down peak or other governing condition occurs at a definite time
each day these switches may be controlled by a timer to open and
close at the required times. Alternatively if the bank B' has a
relay which places it on down peak operation this relay may be
arranged to operate the switches 401 and 403. Such a relay DP is
shown in the aforesaid Santini et al patent.
Provision is made for overriding the sequencer. Thus if the scan
control is operated to its position VB the selector relay BR is
connected across the buses L1 and L2 and the sequencer is rendered
ineffective. Similarly operation of the scan control to its
positions VB' and VB" connects the selector relays BR' and BR" for
energization across the buses L1 and L2.
Certain undesirable conditions occurring on any one of the banks
also may operate to override the sequencer. Such a condition may be
over-long operation of a door-hold button on one of the elevator
cars or of a safety edge on one of the car doors if such a
condition obtains on the bank VB while the scan control is in its
"autoscan" position. Thus if a door is held in the bank VB contacts
EB1 of an emergency relay EB connect the selector relay BR across
the buses L1 and L2 for energization. In a similar manner such a
condition occurring on the banks VB' or VB" results in closure to
make contacts EB1' or EB" to energize the selector relay BR' or
BR". The circuits for the relays BR' or BR" are completed through
break contacts EB2. Consequently if the condition occurs
simultaneously on the bank VB and one of the other banks only the
selector relay BR is energized. Also when the selector relay BR" is
energized through the make contacts EB1" the energizing circuit is
completed through the break contacts EB2'. Consequently if a
similar condition is present on both of the banks VB' and VB" only
the selector relay BR' is energized through these circuits.
The emergency relays EB, EB' and EB" may be energized and picked up
in response to undesirable conditions respectively occurring in the
banks. For illustrative purposes it is assumed that this condition
involves undue holding of the door of one of the elevator cars as
represented by pickup of the timing relay YY in the aforesaid
Santini et al patent for the elevator car A or by pickup of a
corresponding relay for any of the remaining cars of the three
banks. Make contacts YY6 operated by the aforesaid relay YY and
corresponding contacts for the remaining cars of the bank VB are
connected in parallel for the purpose of connecting the emergency
relay EB across the busses L1 and L2. Consequently undue holding of
the door of any of the elevator cars of the bank VB results in
pickup of the emergency relay EB. In a similar manner emergency
relays EB' and EB" are picked up as a result of undue holding of
any of the doors of the banks VB' and VB" respectively.
The master relay ME is connected for energization across the buses
L1 and L2 through make contacts EB3, EB3' and EB3" in parallel of
the emergency relays EB, EB' and EB". When ME picks up, its break
contact ME1 opens the L1 line to the automatic sequencers SQ and
SQA.
Illumination of the up floor lamp UL9 indicates that an up floor
call is registered for the 9th, 18th or 27th floor depending upon
which of these banks is being displayed on the panel TD at the time
of such illumination. To this end the lamp is controlled by make
contacts of floor call registering relays UR for the three floors.
The construction and operation of such relays UR will be understood
from the description of similar relays employing the reference
character UR in the aforesaid Santini et al. patent. It will be
noted that the lamp UL9 is connected between the bus auxiliary LB
and the bus L2 through make contacts 9UR8 of an up floor call
registering relay associated with the 9th floor and a rectifier RE.
The lamp also is connected between the auxiliary bus LB' and the
bus L2 through make contacts 18UR8' of an up floor call registering
relay associated with the 18th floor and a separate rectifier RE.
Finally the lamp is also connected for energization between the
auxiliary positive bus LB" and the common negative bus L2 through
make contacts 27UR8" of an up floor call registering relay
associated with the 27th floor and a separate rectifier RE. The
rectifiers prevent one of the auxiliary positive buses from
supplying current to the others of the auxiliary positive buses
when the contacts of one of the up floor call registering relays is
closed.
In a similar manner each of the lamps UL2 to UL8 is associated with
a separate group of three floors the numbers of which are shown in
FIG. 2. Inasmuch as all three banks serve the first floor the lamp
UL1 is controlled by three separate make contacts 1UR8, 1UR8' and
1UR8" operated by the up floor call registering relay 1UR for the
first floor.
In an analogous manner illumination of the down lamp DL10 indicates
that a down floor call has been registered for the 10th, 19th or
28th floor dependent on which of the three banks is being displayed
at the time of such illumination. This lamp is controlled by make
contacts operated by down floor call registering relays DR similar
to those identified by the same designation in the aforesaid
Santini et al. patent. Thus the lamp DL10 is connected between the
auxiliary positive bus LB and the common negative bus L2 through
make contacts 10DR8 of a down floor call registering relay for the
10th floor and a rectifier RE. Further the lamp DL10 may be
energized by connecting it across the auxiliary positive bus LB'
and the negative bus L2 through make contacts 19DR8' of a down
floor call registering relay for the 19th floor and a rectifier RE.
Finally the lamp may be energized by connecting it across the
auxiliary positive bus LB" and the negative bus L2 through make
contacts 28DR8" of a down floor call registering relay associated
with the 28th floor and a separate rectifier RE. In a similar
manner each of the lamps DL2 to DL9 when illuminated represents
that a down floor call has been registered for one of three floors
the numbers of which will be apparent from an inspection of the
panel TD shown in FIG. 2.
Each of the position lamps P1, PX and P2 to P10 in FIG. 4 when
illuminated indicates the presence at the associated floor of one
of the three A cars dependent on which of the banks is being
displayed at the time of such illumination. To this end each of the
cars is provided with a row of contact segments located on the
associated floor selector and arranged in the order of the floors.
These contact segments are engaged by a brush which moves in
accordance with the motion of the associated car. For example the
elevator car A of the bank VB has a row of contact segments j1 to
j10 arranged in the order of the floors 1 to 10 inclusive. The
contact segment for the floor at which the car is positioned is
engaged by a brush jj which moves in accordance with the motion of
the elevator car A. In a similar manner the elevator car A' for the
bank VB' has contact segments j1', jX' and j11' to j19' arranged in
the order of the floors. The contact segment jX' corresponds to the
positioning of the elevator car A' in its express zone. These
contact segments are engaged by a brush jj' which moves in
accordance with the motion of the elevator car A'. The elevator car
A" has a row of contact segments j1", jX" and j20" to j28" arranged
in the order of the floors. The contact segment jX" corresponds to
the location of the elevator car A" in its express zone. These
contact segments are engaged by a brush jj" which moves in
accordance with motion of the elevator car A".
The brushes jj, jj' and jj" are connected respectively to the
auxiliary positive buses LB, LB' and LB". The lamp P10 is connected
between the contact segment j28" and the negative bus L2 through a
separate rectifier RE. Similarly the lamp is connected between the
segments j19' and j10 and the negative bus L2 through separate
rectifiers. Thus if the elevator car A is at the 10th floor (brush
jj engages the contact segment j10) and if the bank VB is being
displayed, the position lamp P10 is illuminated to indicate the
presence of the elevator car A at the 10th floor. On the other hand
if the elevator car A' is at the 19th floor (brush jj' engages the
contact segment j19') and if the bank VB' is being displayed (make
contacts BR1' are closed), the lamp P10 is illuminated to indicate
the presence of the elevator car A' at the 19th floor. If the
elevator car A" is at the 28th floor (brush jj" engages the contact
segment j28") and if the bank VB" is being displayed (auxiliary
positive bus LB" is connected to the main bus L1 through the
contacts BR1") the lamp P10 is illuminated to indicate the presence
of the car A" at the 28th floor. Each of the position lamps P1 and
P2 to P10 operates in a similar manner to show the location of one
of the A cars at the associated floor. Inasmuch as the elevator car
A does not have an express zone a jX contact segment is not shown
for such car. The lamp PX thus indicates presence of one of the
elevator cars A' or A" in the associated express zone when the lamp
is illuminated.
The rectifiers RE are employed for preventing feed from one of the
auxiliary buses to the other auxiliary buses through brushes and
contact segments associated with the position lamps.
The position lamps for the B, C and D cars of the three banks are
similarly associated with the various buses.
The directions of the elevator cars A, A' and A" are shown by an up
direction arrow or lamp UD and a down direction arrow or lamp DD.
When the up direction lamp UD is illuminated it indicates that one
of the elevator cars A, A' or A" is set for up travel dependent on
which of the banks is being displayed by the panel TD at the time
of illumination. The up direction lamp is controlled by make
contacts provided on up direction relays which are similar to the
up direction relay W shown in the aforesaid Santini et al patent.
Thus for the elevator car A the up direction lamp UD is connected
across the auxiliary bus LB and the negative bus L2 through make
contacts W14 provided on the up direction relay of the aforesaid
Santini et al patent and a rectifier RE. For the elevator car A'
the up direction lamp UD is connected between the auxiliary
positive bus LB' and negative bus L2 through make contacts W14' (on
the up direction relay for the elevator car A') and a separate
rectifier RE. For the elevator car A" the up direction lamp UD is
connected between the buses LB" and L2 through make contacts W14"
(on the up direction relay for the elevator car A") and a separate
rectifier RE. Thus illumination of the lamps VL" and UD indicate
that the elevator car A" is set for up travel.
The down direction lamp DD for the elevator cars A, A' and A" is
associated with the buses in a manner similar to the association of
the up direction lamp UD except that the make contacts of the up
direction relays are replaced by corresponding contacts X14, X14'
and X14" of the down direction relays. Each of these down direction
relays is similar to the down direction relay X of the aforesaid
Santini et al. patent except for the addition of the illustrated
contacts. Thus if the make contacts X14" are closed and the lamp DD
is illuminated together with the lamp VL" the elevator car A" is
known to be set for down direction. The direction lamps BUD and
BDD, CUD and DUD and DDD are similarly associated with the B, C and
D cars of the three banks respectively. The rectifiers RE again
prevent undesired feed of current from one of the auxiliary
positive buses to the other auxiliary positive buses when one of
the sets of contacts is closed.
The bypass lamp BP when illuminated indicates a bypassing operation
of one of the three elevator cars A, A' or A" dependent on which of
the banks is being displayed by the panel TD at the time of such
illumination. By reference to the aforesaid Santini et al patent it
will be noted that opening of the contacts LMS2 of a load weighing
switch result in a bypassing operation. For present purposes the
load weighing switch also closes contacts LMS6.
A bypass lamp BP is connected between the buses LB and L2 through
the contacts LMS6 of the load weighing switch and a rectifier RE.
Thus if the panel TD is displaying the bank VB (bus LB is connected
to the positive bus L1) and if the elevator car A is loaded to an
extent sufficient to cause bypassing (contacts LSM6 are closed) the
bypass lamp is illuminated. In an analogous manner the bypass lamp
BP is connected across the buses LB' and L2 through contacts LMS6'
and a separate rectifier RE for the elevator car A'. For the
elevator car A" the bypass lamp BP is connected across the buses
LB" and L2 through contacts LMS6" and a separate rectifier RE.
Bypass lamps BBP, CBP and DBP similarly are associated with the B,
C and D cars respectively of the three banks.
The lamps F1, VL, BVL, CVL and DVL all are connected in parallel
between the buses LB and L2. Thus when the bank VB is being
displayed (bus LB is energized) all of these lamps are illuminated.
In an analogous manner the lamps F1', VL', BVL', CVL' and DVL' all
are connected in parallel between the buses LB' and L2 for
illumination when the bank VB' is being displayed. Finally the
lamps F1", VL", BVL", CVL" and DVL" all are connected in parallel
between the buses LB" and L2 to indicate when illuminated that the
bank VB" is being displayed.
In the aforesaid Santini et al patent a motor-generator starting
switch MG for the elevator car A is connected across buses L1 and
L2 through certain contacts. The only difference in the present
case is that this circuit is completed through a key-operated
switch KS. In addition closure of the switch connects a lamp VL1
across the same buses through break contacts YY7 which open when an
undesired operation of the elevator car A occurs. For present
purposes it will be assumed that break contacts YY7 are operated by
the timing relay YY of the aforesaid Santini et al. patent. These
contacts open when the door of the elevator car A are hold open for
an unduly long time.
The contacts YY7 are connected in shunt across a flasher 411.
Consequently when the contacts YY7 open, the flasher is introduced
into the circuit for the purpose of causing the lamp VL1 to flash
or operate intermittently. This flashing of the lamp VL1 indicates
that an undesirable operation is occurring for the elevator car
A.
Similar circuits are employed for each of the elevator cars. Thus
for the elevator car D" of the bank VB" a key-operated switch DKS"
controls motor-generator starting circuits for the car D" and also
controls the illumination of the lamp DVL1".
In the Suozzo U.S. Pat. No. 2,695,077 an emergency relay EM is
employed for controlling the operation of an emergency dispatcher.
Break contacts EM6 are added to this relay for the purpose of
controlling the illumination of the emergency lamp EL for the bank
VB. The lamp is connected through these contacts across the buses
L1 and L2. Contacts EM6' and EM6" for similar relays control the
illumination of the emergency lamps EL' and EL" for the banks VB'
and VB" respectively.
Desirably a common buzzer or bell 413 is placed in operation when
any undesired operation of the system occurs. For illustrative
purposes it will be assumed that make contacts YY8 are added to the
timing relay of the aforesaid Santini et al patent for the elevator
car A. These contacts together with similar contacts for each of
the elevator cars are connected in parallel for the purpose of
controlling the connection of the buzzer or bell 13 across the
buzzer L1 and L2. Consequently if the door of any of the elevator
cars is held unduly the contacts YY8 or similar contacts for such
car are closed to energize the buzzer or bell.
