THE ELEVATOR PLANT.
A building so magnificent in size and
construction and so perfect In every thing
relating to appointments for the convent
euce of the tenant and eace of access to all
its apartments would be incomplete with
out the especial feature, nowadays at
tached to all modern structures. of the
elevators. giving speed of access combined
with absolute safety and affording relief
from apprehension or accident.
Ranking foremost among the appliances
with which this building is equipped are
the elevators, which are from the famous
mandatory OF the Cahill & Hall Elevator
Company. located at 214-2l6 Mission street
in this city. The acme OF improvement in
this important Fl I'D of mechanical in
genuity has been combined in the elevator
plant of this great structure. Every device
suggested by cOnsummate experience in
this branch of manufacture has been
avaiIed of until the standard of perfec-
tion has been absolutely reached.
Two elevators have been provided. one
each at the front and rear. TIE ore in the
hallway on Ca ifornia street is to be used
exclusively for passenger traffic, and gives
access to the upper floors, while the other
is placed in the rear, and is devoted exclu-
svey for freight and heavy traffic. The
passenger elevator is of the latest improved
hydraulic type, and is styled the 'Hy-
draulic Compensating Elevator" In this
style of elevator the iron CONFERENCE.-The,
which are so obnoxious in ordinary hy-
draulic elevators. are entirely done away
with, the dead weight of the cage being
counterbalanced by forcing portion
of the water back into the COM
preston tank. The elevator Is equipped
with every improvement known up to
this time calculated for affording the
rFoc fatu nd Nil
arranged that in the event OF the speed at
which it is set bring exceeded it will auto
matically stop within distance Of two
feet. It's capacity will raise fourteen per-
sons at a motion of 600 feet per
minute. although it is the intention
to limit the speed TO 400 feet III
that time. The valve is operated by a
lever in the cage. the elevator being also
equipped with patent cutoff valve which
stops at the upper and lower landings au-
tomatically independent of any action OF
the attendant.
In the superior finish of the car, smooth
ness of operation and perfect safety this
elevator is not surpassed by any in the
country.
The freight elevator has been especially
constructed for raising heavy weights,
such as safes, &C., and is OF the most sub
stantial character in every respect. A
weight of 6OOO pounds can be raised by it
with perfect ease and safety. and it is
equipped with every improvement to
guard against possible accident.
Both elevators are operated by the
pump and CO impression tank system. The
large steel compression tanks are located
in the basement, and in close proximity 10
them and adjoining the engine-room are
the two powerful steam pumps. The
plant, being in duplicate. iusures an un-
interrupted elevator service at all times.

manufacturers, who are now engaged upon
a similar plant for the Union Trust Com

j. q. Grannis. the junior member of the
firm. and were carried to successful COM
pelion under his superintendent.
The entire building is heated. The sys-
tenn of ventila ton used in this building Is
the first that has been successfully applied
to any building In San Francisco and is
known as the Vacuum system.
The air is drawn from the outside to
heaters and thence through galvanized
iron ducts, none smaller than 12x14 inches
in size. thus giving an opportunity of
rapidly changing the air with low velocity
The air is then carried into the rooms
above, where it fills its appointed mission.
An immense fan in the basement is con-
tinually drawing the foul air below. and
thus the atmo sphere OF the rooms above is
completely changed every twenty minutes
