HOW IT IS OPERATED
The conductor uses controlling valve to operate
the elevator; this valve performs the triple service
of admitting water into the cylinder to cause the
plungers ascent; of discharging it, to permit It's
descent; and of combining It. to bring the car to
stop The company's double ported controlling
valve, with its differential safety pilot valve mo-

1t may be remarked that size and strength of
these cables, which are excessive, the service de-
manded of them being considered should enable
them to wear well: indeed. it is said that 1t has
never been found necessary to renew the cables OF
punger elevators. The small costs for repairs in
this elevator are not solely due to the fact that
these are rarely required to be made but also to
the easy access which be had to all the work

ITS SAFETY OFFICIALLY RECOGNIZED.
From among the essential features of elevators its
freedom from repairs must be selected by reason OF
it's vital importance. as most highly recommending
reduction of costs; it is generally conceded for in
stance that suspended elevator out Of repair, or
rather not in first class repair. is a menace TO
human life. The fact that the law requires sucn
tyne of elevators to be equipped with safety ap-
pliances establishes the truth Of the foregolnS
necessity is recognition that with it nothing can

TO- 1T ECONOMIES SPACE
But the question OF economy will not down.
for it will always be the one most considered by
owners. especially owners of the finer class Of
buildings wherein every inch of space counts. The
Standard, which takes up comparatively little
room. should strongly commend itself to these As

IT SAVES DAMAGE SUITS.
There is yet another form of economy which
should invite the attention of owners and which
has thus far only been limited at-they are liable,
as common carriers. to damage suits; and not in
frequently the amounts awarded plaintiffs will
far exceed the entire amount of insurance that can
be carried upon an elevator. And it must be under
stood that manufacturers liability steps IN 20

in The Tribune of February 8. 1904 in which an
official of an elevator company one of the ma
