- the valve casing 6 is shifted about the shaft support 5 by an arm 13 slotted at 14 to receive a pin 15 projecting from one end of an operating'lever 16.

TRAIN Application filed June 25,
To all whom it may concern:
Be it known that LAWRENCE H. LEE, a citizen of the United States, and residing at Tacoma, in the county of Pierce and State of Washington, has invented certain new and useful Improvements in Train Lights, of which the following is a specification.
This invention relates to an improvement in signal lamps, adapted more particularly for use on railroad trains.
The objection to the use of electric current for such lamps is, that such current is liable to failure or the bulb liable to turn out, and as it is absolutely essential that the signal lamp be kept burning at all times required for use, universal recourse has been had to the usual oil as a source of illumination for such lamps.
The present invention is directed to a signal lamp designed particularly as an electric lamp, the lamp including however, a burner for gas supplied from a suitable tank or reservoir, with the construction such that in the event of failure of the electric illumination for any purpose, the gas burner will be automatically shifted to the proper illuminating point, the gas ignited, and maintained until the electric current is restored, whereupon the gas is automatically cut off, the burner shifted from the illuminating position, and the electric bulb properly positioned to furnish the source of illumination.
In the drawings:
Fig. 1 is a View in elevation partly' in section of the improved lamp.
liig. 2 is a horizontal section taken. thru the illuminating chamber, the operating parts being omitted.
Fig. 3 is a side elevation of the same.
Fig. 4 is a diagram of the circuit for the gas burner ignition.
Fig. 5 is a diagram of the circuit for the energizing of the electric control and illumination.
Fig. 6 is a view in partial section of the bottom of the casing, showing the indicator in plan.
Fig. 7 is a side elevation of the same.
The improved signal lamp comprises a lamp casing 1, which for the purpose of the present invention, is divided by a transverse partition 2 into an upper or illuminating chamber and a lower or mechanism chamber. The casing in the upper portion is provided with the usual lenses 3, and rising from the LIGHT.
1921. Serial NO. 480,385.
In the automatic operation of the structure to be hereinafter described, it is designed that either illuminating means, gas or elec tric light, in use at the particular time, shall occupy an advantageous position with respect to the lenses 3, the mechanism thus shifting the gas or electric bulb, as the case may be, into that advantageous position according to which particular illuminant is to be used. Obviously, the valve 7 is controlled in the shifting of the casing 6, so that when the gas burner is upright, or in the illuminating position, the valve will be open to admit gas to said burner, while when the valve casing has been shifted to move the electric bulb into the upright or illuminating position, the valve is closed to cut off the supply of gas.
The valve casing 6 is shifted about the shaft support 5 by an arm 13 slotted at 14 to receive a pin 15 projecting from one end of an operating'lever 16. The lever 16 is pivotally mounted at 17 upon. an upright 18 rising from the partition 2, the short end of the lever beyond the pivotal mounting being connected to a rod 19, which is operative thru the partition.
Arranged below the partition is a sole noid 20 and a core 21 thereof is provided at the lower end with a head 22 and is con nected at the upper end at 23 with the lower end of the rod 19. Thus, when the solenoid is energized, the rod 19 will be at its upper limit of movement, in which position, the electric light bulb will be in illuminating relation to the lenses. Upon the deenergization of the solenoid, the core will drop by gravity, operating the lever 16 to shift the gas burner into operative position. That is to say, the parts will be in the positions illustrated in Fig. 3.
In Fig. 5, the diagrammatic circuit for the use of electricity as an illuminator, is shown to comprise conductors 37, 38, leading from the train source of electric current thru the lamp 9 and solenoid 20. This circuit may. if desired, include a hand switch 39, by which the control of the current may he had. for initial uses of the lantern. In Fig. 4: is shown the ignition circuit for the gas burner, wherein one side of. the battery 10 is grounded, the other side leading thru the primary 41 of the spark coil, the contacts 35, 36, and to ground. The secondary 42 of the coil is grounded at one side and leads thru the spark gap 25 and then to ground.
From the above description, it will be obvious that so long as the train circuit remains in tact, the signal lamp will be lighted by electricity. Under these conditions. the solenoid will be energized, and the rod 19 maintained in its upward limit of movement. If however, the current fails 01' the lamp burns out, the solenoid is deenergized, the core 21 moves downwardly by gravity, the lever 16 is operated, the arm 13 moved, and the valve casing 6 turned on its axis '5. This operation moves the gas burner into illuminating position, at the same time oaenin u) the as su l-'. As
CD D
the rod 27 moves upwardly in this operation, the primary of the spark coil is energized in the manner previously described, and a spark is generated at the gap 25 to ignite the gas issuing from the burner 11.
If the train current is reestablished, the solenoid is again energized and the parts moved in an obvious manner to shift the electric bulb into illuminating position, cut off the gas from the burner 11, and move said burner out of illuminating position.
It is deemed advisable, though not essential, that an indicator be arranged on the signal lamp to advise the trainmen as to whether the lamp is illuminated by electricity or gas. To secure this result, there is arranged in the bottom of the casing a shaft 4C3 mounted in bearings 14; and projecting thru one wall of the lamp casing, being provided on its projected end with an indicator or pointer 4.5. A spring 46 connected to the bottom of the lamp casing and cooperates with the shaft 43 to hold the latter normally in a position to indicate that the lamp is being illuminated by the electric current. An arm 47 is secured to one end of the shaft in line with the head 22 of the solenoid core 21. Thus, as the electric current fails and the core drops by gravity, the head 22 will engage the arm 47 and turn the shaft 43 against the tension of the spring 46, moving the in-- dicator 46 to a position to indicate the use of the gas as an illuminant. The parts will remain in this position until the electric current is restored.
