I have come to regard an elevator indicator with a feeling of wonder.
Some years ago, when the "planchette" first came out, I remember that
it acquired quite a reputation as a particularly erratic piece of
mechanism, but for real mystery and _innate cussedness_, on general
principles, commend me to the indicator. Why, I have known an indicator
after registering a nice water bill, to deliberately and without
provocation commence taking it all off again, by going backward. This
crab-like maneuver the agent readily explained by saying the "ratchet
had turned over," but even he was unable to show us how to make the
bills after these peculiar gyrations. I also find that it is quite a
favorite amusement for indicators to stop entirely, like a balky horse,
after which no amount of persuasion will bring them to a realizing sense
of their duty.
Even at the best, these indicators are very apt to get out of order,
necessitating greater watchfulness in supplying elevators than for any
other purpose for which water is furnished.
Accidents in connection with the use of elevators are common throughout
the country, and in Kansas City had, until within a short time, become
of altogether too frequent occurrence. The great cause of this I believe
to be due to the fact that the parties who usually operate elevators
are the very ones who know least about them; the corrosion of pistons,
crystallization and oxidation of cables, and many other disorders common
to elevators, being matters they do not comprehend. The frequency
and fatality of these accidents in Kansas City finally led the city
authorities to appoint an Elevator Inspector, who is under heavy bond,
and whose duty is to examine every elevator at least once a month, and
to grant license to run only such as he deems in safe condition. Thus
far since the establishment of this office we have had no serious
accidents, which leads me to the belief that in most cases a monthly
examination will discover in time the causes of many terrible
casualties; also that it is not safe to operate elevators unless so
inspected by some competent person.
The hatchways of elevators in large buildings are points greatly feared
by firemen. They well know that when a fire once reaches this shaft, it
takes but a moment for it to be carried from floor to floor, until the
building is soon past saving. Although this great danger is well known,
it is the exception rather than the rule to provide elevators with
fire-proof hatches. A properly constructed elevator should, it seems
to me, be provided with hatches, or better still, built within brick
fire-proof walls, with openings to be kept closed when not in use. In
this way costly buildings, valuable merchandise, and many lives would be
saved from fire every year.
