ELECTRIC MOTORS.
The Uses to Which They Are
Being Put in San Francisco.

The comparatively recent extension OF
the underground electric conduit system
from Spear and Market streets on the east
to Market, Hayes and Larkin streets on
the west has rendered possible very wide
use of electric power, to say nothing OF
electric light, under the most advantage
Gus circumstances. From Market street
there are underground branches of the
system extending along Mason, Eddy,
Powell, Stockton, Ellis, Grant avenue,
Geary, Kearny, Montgomery, Post, San
some, Suffer, Bush, Battery, Pine, Califor-
MIA, Davis and Drumm streets, while on
the south side of Market street the con-
duits are laid on Third and Main streets,
are being put in on Mission, and are to be
laid on Beale, Fremont and First streets.
In the large area covered by this system
all kinds of machinery are driven by cleo
trio motors operated by the tapping of the
underground wires. Some idea of the va
ried uses to which this electric motive
power is put may be conveyed by quoting
the different establishments in which the
power has been installed since the begin
ming of the current year: Frank d Co.,
leather-trimming machinery; J. G. Nolan,
shoe MANUFACTURER San Francisco Plating
Works; Eagleson & Co., sewing ma
chinery; II. Block & Co., gloye-making;
store supplies, etc.; Columbia WOODEN
mills. clothing; EUening Post, type-setting
machinery; John Hoey, woodworking
machinery; Odd Fellows Hall, driving
pumping machinery; Pope Manufacturing
Company, bicycle repairing machinery;
Shasta Mineral Water Company, bottling
machinery; Peoples Palace, for the Royal
Uot (1ar II
Publishing, routing machines; Mark
Strouse, sausage machines; Rothschild q
Wise, sewing machines; Schroeder Paint
Company, paint mixing machinery;
Heyneman e. Co., sewing machines; Re-
we're Rubber Company, rubber making
machinery.
No less than six hundred different es-
adjustments thus use electric motors for
the operation of machinery of different
kinds or for the driving of their elevators.
AT present about so per cent of the motors
are employed to operate elevators, and
among those buildings in which the n.y.
draullc rams operated by electric motors
have been recently introduced are the fol-
lowing: Delmonico; Gutzkow, on Market
street, between Fifth and Sixth; Berk-
SHIRE Hotel; Hillsdale Hotel, on Sixth
street; Pacific Union Club, and Dewey
& Co.
Quite recently new form of elevator
mas been invented and is now to be seen
IN operation at the works of the Electrical
Engineering Company on Main street
This is an elevator operated directly by
electricity without the Intervention of any
other power Architects and elevator
men who have seen it at work are unani-
nous in approval of it. The peculiar adj
vantage of the elevator is that it only uses
Just sufficient power to perform the work
required of it. There is no waste of power.
In the ordinary hydraulic elevator the
maximum power is always put forth
whether the load to be moved is great or
small, thus entailing considerable waste
OF power. In the electric elevator the
power automatically adjusts itself to the
load to be moved.
The advantages of using power from
central source of supply are very numer-
Gus. The motor occupies very little space
as compared with the room required for
steam engine and boiler, the power-user
always knows just how much power he Is
using and can cut it off instantly when he
does not require it, having no fires to bank,
no steam to keep up until it is needed.
The doctrine of centralizing power is
comparatively new one, and seems likely

cisco.
