8.  Q. What is the duty of the engineer in event of his discovering a safety appliance which is in an unsafe condition when taking an engine from roundhouse territory?

A. He should report at once to the person in authority so that necessary repairs may be made before engine goes into service.

=Pyle-National electric headlight=

1.  Q. Why are electric headlights applied to locomotives?

A. Electric headlights are applied to locomotives so that the engineer may have a clear view of the track for enough ahead of the train to enable him to protect the company’s property in his charge.

2.  Q. How far ahead of the engine should the arc headlight illuminate the track?

A. Not less than from fifteen to twenty telegraph poles.

3.  Q. State how you would focus the lamp.

A. First, would adjust back of the reflector so front edge of reflector will be parallel with front edge of case.  Second, adjust the lamp to have point of copper electrode as near the center of reflector as possible with carbons as near the center of the chimney holes as you can set them.  Third, have the locomotive on straight track.  Now move the base of the lamp around until you get a parallel beam of white light straight down the center of the track, then tighten the lamp down.

4.  Q. If the light throws shadows upon the track, is it properly focused?

A. No.

5.  Q. If the light is properly focused, that is, if the rays are leaving the reflector in parallel lines, but the light does not strike the center of the track, what should be done?

A. When the light rays are thrown out in parallel lines and they do not strike the center of the track, it denotes that the headlight case is not set straight with the engine, and the entire case on base board must be shifted until the shaft of light strikes the track as desired.

6.  Q. What can you do to insure a good and unfailing light for the entire trip?

A. By carefully inspecting the entire equipment before departing on each trip, and know that there are no wires with insulation charred or worn off, that all screws and connections are tight, commutator clean and brushes set in brush holder in proper manner.  Carbon in lamp of sufficient length to complete trip, and that the carbon will feed through the clutch freely and rests central over the copper electrode.  Copper electrode cleaned off, oil in both bearings and see that steam does not blow at stuffing box gland.

7.  Q. What kind of oil and how much would you use in the bearings of the electric headlight equipment?

A. Would use the best grade of black or engine oil furnished for both bearings and only enough oil in oil cellar that the revolving loose oil ring may trail through the oil.  When bearings are supplied with oil cups, use a heavy oil such as good engine or valve oil.
