RUNNING-LIGHT SYSTEM AND ,B OARD.

Application filed August 22, 1928 Serial No. 658,799'ir.

To all whom it may concern:

Be it known that I, JOHN W. HAYWOOD, a citizen of the United States, and resident of the borough of Bronx, county of Bronx, city and State of New York, have. invented certain new and useful Improvements in Runnin -Light Systems and Boards, of which t e following is the specification.

The invention relates to running light systems for ships. The invention comprises an improved system wherein each of the ships signals contains two lamps, as is not uncommon, and in which the circuit branches for the two lamps are controlled jointly by a relay and a' switch, in such manner that the switch will complete a path through the coil of the relay and one or other of the branches, according to its position, while the armature of the relay is, adapted automatically to complete a path through the switch, remaining in position, to the other branch, upon failure of the lamp then in circuit with the coil. Upon throw ing the switch the lamp automatically lighted by the armature remains burning, because, while the path established by the armature is broken, a path is restored through the coil and the branch containing this lamp. The relay for each of the running lights controls an indicator on the board corresponding to that light; and in addi-,

tion there is a common alarm the circuit of A which is branched to each of the relays,so

that upon failure of a lamp of any one or more of. the lights this alarm is sounded, calling attention to the condition shown by the indicators. Preferably there is a dual indicator on theboard for each running light, comprising a lam and a luminous indicator card, or legen -bearing member, the latter being read-able in the dark even if the corresponding indicator lamp should burn out.

In the' accompanying drawings forming a arthereof:."

g. 1 is a front elevation of a four-panel board embodying the invention, with one of the panels removed;

Fig.3 is across-section through the frame and one of the panels, the intermediate and major portion of the panel being broken awayfor economy oispace; and

' Fig. 4 is a fragmentary side elevation of a relay. 1

Similar reference numerals indicate like parts in all the figures where they appear.

The board has a main panel 1 and any desired number of panels 1, connected, respectively, with different running lights. The panels 1 are duplicates of each other, and the board illustrated contains three of them, though thenumber may be varied.

The main panel bears a main double-pole single-throw switch 2, fuses 3, 3 and abuzz er 4. Each. of the panels 1 has a triple-pole double-throw switch 5, a fuse 6, a relay 7 and a lamp 8. The wiring will now be explained.

The characters 9, 9 designate the conductors of the supply line, connected with the blades of the double-pole switch 2. Each of the running lights or signals of the ship contains two lamps 10, 10, only one of which receives current at a time. It will be sufficient to consider the main circuit, one

of thevsignals and its circuits and devices.

With the main switch 2 closed and the switch 5 of the adjacent panel 1 in the left-hand position seen in Fig. 1, the circuits may be traced as follows: from line wire 9 and one of the poles of switch 2, to conductor 11 on the panel 1, said conductor having fuse "3 therein, to a main wire 12 on the frame 13 of the board, to conductor-1.4; on the panel 1, to the pivot terminal 15 of 1 one ofthe blades of the switch 5, thence to switch contact 18 at the left, thence by conductor 21 to corresponding contact 18" at the right, to conductor22, to connection 23 connected with the armature 24: of the relay v7, by conductor 25 to the coil 26 of this relay, through the coil to conductor 27 to the mlddle pivot terminal 16 of the switch, through the middle blade to the contact 19 at the left, by conductor 28 on the panel 1 and external conductor 291to the lamp 10 of the signal, by conductor 30 back. to the panel 1'9, by conductor 31 on the panel, containing fuse 6, to conductor 32 on the frame, to main conductor 33 on-the frame, back to panel 1, to. conductor 34 thereon, to conductor 35* containing fuse 3, to the other blade of the switch 2, to the othersupply line 9. If the lamp 10 burns out, the circuit through the coil 26 of the relay is broken and its armature 24 drops, forming electrical connection with two contacts 36 and 37. Thereby circuits are established as follows. Current still flows as just described up to the connection 23 at the armature of the relay. Thence the current passes through the armature to contact 36, thence by conductor 38 to the pivot terminal 17 of the switch 5, through the upper blade of this switch to contact at the left, by conductor 39 to middle contact 19 at the right, by conductor 40 on the panel and external conductor 41 tothe lamp 10 thence back by conductor to the panel, and from this point on as with the clrcuit prev ously traced. Lamp 10 is thus automatically lighted upon the failure of lamp 10.

'Another circuit branches from the switch terminal 17 through conductor 42 to indicator lamp 8 on the panel 1*, which is thus lighted, to conductor 43, to conductors 32 and, 33 on the frame, and thence back to the supply line as previously traced. In addition to this indication controlled by the armature 24 of the relay, the dropping of the armature itself gives an' indication bymoving the word Burning away from a window in the relay case and bringing the word Out into View, these legends being printed in luminous paint on a suitable card 8 carried by armature. Thus, a double indication is given, and in case the lamp 8 should be out of order, the armature, or electromagnetic device, controlling its circuit, will still afl'ord a signal which is readily discernible in the dark. I

A. third circuit can be traced from the contact 37, by way of-conductor 44 on the panel 1 to a main conductor 45 on the frame, to conductor 46 on the panel 1, to

the buzzer 4, which is energized, by conductor 47 to the conductor and thence backto the supply line. This alarm or sigand inserts a fresh lamp in placeof the denal is given, therefore, when a lamp of any of the ships running lights goes out.

Warned by the alarm the person whose duty it is goes to the board and by the indication on one of the panels 1 is advised as to which of the running lights contains a burned-out lamp. He then throws the switch 5 of thispanel to the other position; that is to say if he finds it at the left he throws it to the right, while if at the right he throws it to the left. Either position is a normal position. He then goes to the light ment of the switch 5 away from contact 20, but another circuit is closed which includes this lamp and the relay coil 26. This circuit includes conductor 14, pivot terminal 15, contact 18, conductors 22, conductor 25, coil 26, conductor 27, pivot terminal 16, contact 19 conductors 40. 41, lamp 10 conductors 30, 31, and so on back to line. The coil 26 being enerized, its armature is automatically raise thus removing the Out sign from View and restoring Burning, and breaking the circuitthrough the buzzer 4, which ceases to sound.

, If now lamp 1O burns, out, (lamp 10 having been replaced), the circuit through the coil 26 is broken as before, the armature drops, and a circuit is completed from the contact 36, through conductor 38, pivot terminal 17, the upper blade of the switch 5, contact 2O at the right, conductor 39" to contact 19, through conductors 28, 29 to lamp 10, back by conductor 30, to conductor 31 on the panel, and so on back to line.

When the-switch 5 is again thrown to the left, *the circuit is again established through the coil 26 and the branch containing the lamp- 10, the armature 24 is restored to its normal condition and the indicators andv alarm are also restored to normal condition.

The board itself will now be described. The top and bottom members of the frame have internal back flanges or ledges 50. In these are mounted forwardly projecting studs 51, three at top and two at bottom in the case of the panel 1, and three at top and three at bottom in the case of each of the panels 1*. These studs are clamped to the flanges by collars 52 at the front and nuts 53 in recesses at the back. The collars '52 may be fast on the studs or abut against shoulders thereon. Wire terminal brackets 54 are clamped between the collars 52 and the flanges 50, in electrical connection with the. studs. The wires which run along the frame are secured to the terminal brackets by binding screws 55. The precise construction and arrangement of the studs and terminals may, however, be varied, though that illustrated is thought to be especially advantageous. I

The terminals 56 of the wiring on the panels preferably compriseplates or strips secured to the backs of the panels by screws 57. These terminals, are located on the board with reference to the corresponding terminals on the frame. In the present construction holes 58 are formed through the panelsand their terminals 56, in positions to take over the studs. This done, insulated nuts 59 are screwed on to the projecting threaded ends of the studs, and the panels are thereby clamped to the frame, and their terminals at the same time electricall connected with "the terminals on the e,

- cuits comprising branches for two lamps, a

without fuss or difliculty. Spring washers 60 may be interposed between the terminals 56 and the collars 52.
