This invention relates to 'a safety remote control andlocking. system for doors or gates,`. particnlarly -t-hose o n rapid transit. 'electricvcars o notber` public utility vehicles, and'ha's for its'object: first, theprovision o'f a locking system controlled and operated independently of the door operating and vcontr'ol system whereby closed 'are locked in that position and are the doors' .When 6 with -the locking system to show the locked or unlocked condition ofthe doors;1second, the'provision of a simple and effective door lockingV device which automatically operates upon closure of the door to lock itf'in`its closed position and whichrnust positively lactuated before. it is possible to open thea To'jthis end,"lockingdevices are 'atlixed 'adjacent'to one or more doors' and are pro- :videdithf'associate 'devices for selective v' actuationthreotand for operating .the 'in I i dica't'imfineanslf-l The indicating means" o'pf' eratedV-by' these Vdevices' -naly be located in af guards'g'positfip'n'and'at'such other positions onthecali.' train or lvehicle as'will best l .serve to"- indicate .tothose' in charge .of theA doors-the locked orvunlocked position of any or--allcar do'rsf'' One' embodiment'of' the .lo :ki|igdevice which has been found to be particularly effective and which is readily adapted for use in conjunction with the electro-pneumatic door opening an'd closing controlsnot'v in "general use comprises` a pivoted latch or bolt or other member positively retained, which is adapted to lock and hold the door in its closed position until a retaining latch is released. Other'forms of the 'locking device may be' employed which may omit the retaining latch or have other modifications which are suitable for the place or position in which they are iised. The control system for tlielccking device operates the locking.,lr device' independently of the door opening;r and closing system and 'requires the operator to manipulate the lock-v ing control before the door opening control or 'to manipiilate the combined control ac' gram. vIn. order thatthelocked or -unlocked condition of the doors may be indicated to the operator or others, a system.

of electric' vsi als may be employed which are controll vhy means associated lWith-the Alcks. In this'way, the-operator ormotor-jj man or both are informed whether'for not" the door or doors are actually-locked or 'unlocked rather than -merely closed'orv-open.

In accordance with the invention; the

door operatingmechanism and the locking mechanism may b e either electrically, mech'- "anically or pneumatically controlled or operated by independent systems, or' one 'may be controlled vby one forml of these 'energies and operated -byfanotherfand vice versa or an other independentactuating means or combination of actuating Ameans may be employed. t

Heretofore, it has utilize one control to both'f'releas'e the locking' device and vopen -thedoors ofv a'. car or the like. In some cases; movement ofthe open ing means effectedthe release' of the locking means. The' locking of doors has also been obtained moving the'door opening lever` East deadcenter.' All of these' methods have een found-to be exceedingly j rinsatisfactory in that 'they `provideno positive" system' of locking andA indicating theloeked condition, 'the' cont-rol and operationbfwhich 'was' in" de'pendentl'of the doorjcontrolfa'nd Operating system.` It' was quite' possiblein these sys-v "tem's for passengers to intentionally or va'c' eidentally 'manipulate' the vsingle vcontrol andI l cause'the door'or doors to open.; Moreover,

in some systems passengers .could 'actually l v forcet'he door open against the air -pressure holding itor tripth'e small'latch securing it andthus vgrain entrance after the doors were closed by the operator and when the car was ready. to sta-rt'.

It is often the ease that doors'heeomestuckl in he closed position so' that the door opening evice does not'ex'ert sufficient force to open the door, but, however, exerts a ,con-

In these dmwings:

l `ig. l is a, vie-.v of one form of the device as applied to :i door and shows schematically thc arrangement and relation of the door opening,r device, the-locking,r means and the indicating means. i

F ig. 2 is a sectional view of a preferred form of locking mechanism.

Fic'. 3 is a view showing an arrangement of electric switches for the indicating means. F ig. 4 illustrates a wiring diagram of the lock release mechanism, the fuards iiidicatin lights and the motormans indicating lig its and F ig.l 5 shows the positions of the indicator light switch and circuits.

`vReferring now to Fig. 1, a sliding ca'r door 4 is .shown with its pneuniatically open ated actuating cylinder 5, the operation of which is' controlled by the electrically oper? ated valve 6. .The iston within the c linder 5 operates the oor 4 by means ov the arm 2 and associate devices. The apparatus enclosed by the dotted line 7 .comprises the locking and indicating devicepro'per. The arm 8 is adapted to catch and hold the door as shown and a retainingr lever 9 is adapted to be operated by the solenoid 10. The can block 11, l'iearing switch contacts, is arranged at one end of the lever 9. The indicatin lights, for example 12 and 13, are controller by' these switch contacts and are adapted to indicate to the guard or other train-man, the lockedor unlocked condition vof the doors, but additional lights and circuits may be provided for, indications at other places if desired. T he switch 15 controis theopening'fa'nd closingr of the door and the switch 14g preferably a push button, controls the unlocking of the door. VThese two controls arei'ilaf'eilfso as to be convenicntly. 'opcratcdsimultancously or selectively with one hand-and tfhe indicating lights are ilaccd'so, to be veasily visibleV to the guard. The eucrgryfor the electrical circuits may be 'supplied from any convenient source.

The operation of the system shown in Fig. 1 is as` follows: l'n order to o en the door 4;, which is shown in the close position retained by thelocking arm 8, the guard first operates the lock control switch 14. This.

encrgizes the solenid 10 which iictuates the lever'!) withdrawing itfroin its retaining position bclnnd tlie`arni 8 and at the same time changing the cani contacts to, indicate When 1 6 automatically forces the arm 8 intolmi# tion behind the door 4 and draws the retain-f ing lever 9 into place. behind `the locking:r arm"l 8. Should the door opening control switch be operated without previously operatingA the lock release switch, the door would bc prevented from opening as it could not push the arin 8 out of its path,pdue to the'inter.

locking action' of the arm 8 .with the retain'- ing lever 9. A series circuit 18 includes si' lamp 12, preferably green, vand the contacts 17 on the cam 11. If only one Vlock is used, the circuit will be completed through ,con` ductors 53 and 54; ordinarily, however,

more than onev door' is to'be locked. and the2 conductors 53 and 54 .lead tk the locks on the other doors and includecontacts such' 113,17' on each lock.. When all doors'are closed and `locked all the contacts such as 17 will be closed by a wiper 55, the series circuit 18 will be oomplete'and the `lamps 12 will'be lighted. It is to be noted that the circuit 18 is included in each of the door indicating sstenis and requires 'that al! doors be loc edbeforethe circuit is coinlete. A multiple circuit 40 includes a amp 13, preferably red, and the contacts 19 on the ca m 1l. A similar circuit provided for each lock used and it is preferable for simplicity that all these multiple circuits include thesame red lamp I3. door or doois'be 'open the lamp 13, preferably red, will be lighted duc to its circuit being completed at 1 9.

The locking and switching device is best understood by reference to Fig. 2. The metal box or ytraine 7 supports and contains the entire device and 'is provi led with lugs or holes 20 for attachment tithe frame or other portion of the car. 'l`li ox structure is divided by a diagonal web"2l for reinforcement against great strain brought abou'lI by an attempt to open a locked door. arm 8, suitably shaped. is mounted within the box 7 on a pivot 22 and extends thri'mgdi an opcniin.f 255 in thc bok into the path of the door which it is desired to lock.

In order to indicate the unlocked condition of any door, a multiple circuit is provided, which includes two Ifeeders 57 and 59, the feeder 57 having a tap .for each lock except G and E nnd being connected to the ground through the red lamps 13, and

the feeder 59 haring a tap `for cach of the locks and including the positive' terminal of the energy .'-ource'.v A lead 60 is brought to the locks (i and E from the contact 61 on switch' 52. The function of switches 52 will lm explained iii more particularity hereinalici-hut for thc present it is sutlicient to say that in one position the contact (il is connected to contact 6i'. thereby forming a complete circuit throiighthe red lamp 13 to thc ground. It will lie sccn that by this arraugeiiicnt if tlietwo taps 40 at any lock are connected together, thc circuitwill he tomplete-.d through-the red lamps 13. .The contart 33 on the cani liloclc l1 is provided toA complete -tliis circuit wh'encvcr its door is un locked.

ln order to provide an indication for the motorman of thc locked condition of all the doors; :i separate circuit 43, which asses in 'turn through all the locks on all tic doors,

is provided: Assuming that A is the head end of the train :ind thc switch 48 atV that end is thrown so as to close contacts 51, the circuit 43 through the i'notormans signal lli will be completed through the lead 58, which includes in order the contacts 3l in doors E, D, B, C, F and G. The switch l# at the other end of the car should be thi-own so as to connect the terminals 49,. which continues the circuit through the.

j uiii per 47. which is adapted to he connected to thc next can which is similarly arranged. The circuit then passes through all the other' locks in a similar manner and at the rear end of the ti'ain the cir'cuit is completed to the positive terminal of the energy source preferably through switch 50, which is closed only when the reaisignal lamp is mounted. When all of the doors of the train are closed and locked, the circuit43 will be completed ii means of the contacts .'51 on the cam blocks ll, and the motormans signal light 46 will be lighted. Should an) door become unlocked. the circuit will lie broken andthe light 46v will be extinguished. The switch 48 is provided to enable the car to be used in any position in the train and to enable the motorman to operate his door without open-circuitingliis indicating lamp. When the contacts 49 of this-switch are connected the car may be used as a rear car or in an intermediate posit-ion asA the lead 5B is disconnected from the signal 46 and is connected to the lamp switch 50 and jumper terminals 47.

.. lVhen used as a rear car2 the rear signal lamps 'must be mounted in order'to-close motormans door willv now,V comp the switch 50 which controls the energy connectiohs for the motormansfsignal circuit. Thusra positive indication is given to the inotorinan that tlie rear signal lamps are mounted.V When caigcurrcnt is ieiceive'cl and the motormans circuit established through the jumper terminal 4i'. When the switch 48 is thrown so as to-eonnect the terminals 51 the lights 46 are in circuit and this end of the car may he used as tliehead end of the train.

The yellow light circuit 42 is providedA so that the iiiotoriiian may operate his door without confusing the guard on that-.car by lighting the redf'light. To this end the switch 52 which. has been previously referred to is provided which has two positions. In the iosritionstX und Y)shown in Figure 5 t c contacts' Gl'and 63 are connected to contacts 62 and 64 respectively, thereby clos-ing in iosition X the red light circuit 40 am "the green light circuit 18Aat the A end 4of lthe car. .'-nd disconnecting the yellow light circuit 42. In the `other` position the're'cl and greenlight circuits 40 and' .18 through the motormans door E and the adjacent oor D are open and the yellow light circuit 42 is'closedi ln operation the switch 52, which is onthe front end ofthe train, is-thrown' .so that the yellow light circuit is closed and all other switches 52 are thrown so as to connect the red and green light circuits. The unlockin of the ete the yellow light circuit 42 instead o the red light circuit 40 by means of the contact 33- and will ive'a yellow light indication to the guardewho under theseconditions is at thevother end of the car. Should any other door be unlocked, thc red light'circut 4U will be closed as usual and the guard may have a red light indication and a yellow light indication. When all doors .are locked except the motorinans, 'the "guard will have a yellow light indication and a as an intermediate L' green light indication, which for the head car will signify the locked condition of` all doors and will enable him to signal to proceed.

From the foregoing it will be understood that this system of door or gate control provides a simple and ellicicnt means of climi conditions to be met, "the arrangement of meer@ the door locking System and the construction of the various parte may be modified accordinglyA Ielaim:
