A. About 30.
13. Q. How often should the ball bearings be oiled?
A. About three times a week.
14. Q. How often should the governor be oiled?
A. Before leaving every trip.
15. Q. What kind of oil should be used?
A. Valve oil.
16. Q. Is it necessary to clean the electrode every trip?
A. No.
17. Q. Why?
A. The dynamo is provided with shunt fields which build up the current regardless of the arc light.
18. Q. What are the two causes of lamp burning green?
A. Speed too high, or wires to the lamp being reversed.
19. Q. If the carbons burned away too fast, but otherwise the lamp appeared to be burning properly, where would you look for the trouble?
A. It would indicate that tripping spring No. 209 was too tight.
20. Q. If tripping spring No. 209 was being annealed from heat and sparks were noticed at the clutch, where would you look for the trouble?
A. Flexible wire No. 251 would be broken.
="BUDA-ROSS" ELECTRIC HEADLIGHT=
1. Q. What are the three essential elements in the "Buda-Ross" electric headlight equipment?
A. Steam turbine engine, dynamo directly connected on the same shaft, and self-focusing arc lamp.
2. Q. At what speed should the turbine run?
A. 2,800 revolutions per minute.
3. Q. How is the speed controlled?
A. By a centrifugal governing device.
4. Q. How does the steam enter the turbine?
A. Through a main valve which is perfectly balanced in all steam pressures directly and impinged on the buckets directly from a nozzle.
5. Q. About how much opening should this valve have?
A. About one-fourth of an inch.
6. Q. Can the lift of this valve be changed?
A. Yes.
7. Q. How?
A. By adjusting the inner sleeve of the valve with a common monkey wrench after removing cap nut on top of turbine.
8. Q. Can this be done while the light is burning?
A. Yes.
9. Q. What is necessary to do this?
A. Take a monkey wrench and screw the inner sleeve down to the right to reduce the lift, and to the left to increase the lift. In reducing the lift you reduce the speed, and by increasing the lift you increase the speed.
10. Q. Is there any other method of setting speed?
A. Yes.
11. Q. How?
A. By removing oil box on the turbine cap and adjusting the nuts on the governor studs on the face of wheel.
12. Q. Is any provision made for operating the light with low pressure steam?
A. Yes.
13. Q. What?
A. An auxiliary valve is used which operates automatically at any predetermined pressure, which is adjusted by an adjusting stem at the bottom of the engine and which can also be adjusted while the light is burning.
14. Q. What kind of oil should be used in the "Buda-Ross" bearings?
A. Cylinder or valve oil.
15. Q. What style of generator is used.
A. An iron-clad type with no outside magnetism.
