Here is what it is:
<Safety Derrick Lamp, more commonly know as a Yellow Dog Lamp or Yellow Dog Lantern, because when seen from a distance it was said that the yellow flames looked like the eyes of a dog. Patent number 126,688:
In an oil region the greatest care must be taken to provide safe lamps for use about the derricks, where they have to be suspended at various heights, and are liable at any moment to be struck by a shaft, or by the carelessness of a workman be knocked down or dropped.
...the accidental fall of a lamp, or failure to tightly secure the lid, might ignite the ever-present oil, which would communicate instantly with the well, and thus destroy, maybe, hundreds of thousands of dollars' worth of property, and, what is not at all unusual from this very cause, many lives.>
