LOCAL MACHINERY
FOR OIL IN DEMAND

lures of Pump Governors

ing in large quantities the machinery
which is necessary 10 develop oil con-
sumption. Foremost among the ma
chimes Of this kind built here are oil
burners, pump governors and distillate
running gas engines.
The George Z. Witt company of this
city is one of the firms that deals in
the exclusive manufacture of oil pump
governors and other oil machines and
that sends its finished products to all
parts of the world where oil burning
machinery has been installed. The
pump governors, which form an impor-
tant part of its output, are used for
adjusting and regulating the pressure
Of oil pumping machinery.
Among the other machines and ac-
cessories manufactured by this firm for
use in consumption of oil, which is rap
idly becoming the fuel of the western
world and extending even to the big
mills and factories OF the east and Eu-
rope, are reducing valves, relief valves,
safety valves. oil valves, Little Giant"
improved oil burners. oil pumping sets.
duplex oil pumps, oil heaters, oil tanks,
oil tank gauges, automatic oiling de-
vices, sight feed lubricators and auto
matte oil burner governors.
PUMP GOVERNORS SOUGHT
For the pump governors and the au-
tomato oil burner governors there has
recently been z greater demand than
ever before. This company has been
kept busy supplying all oil machinery
markets, as manifested by its last order
from the Southern Pacific company,
which uses its type Of pump governors
almost exclusively.
the r~pSpnf time there are more
than 1000 of these pump governors in
daily operation, with orders coming in
steadily from every market where oil
is used. They are being operated by
the Southern Pacific railroad, the Ore
zon Short Line. the Western Pacific,
the California Northwestern, the United
States navy for both stationary and
marine purposes, the Wells-F Fargo COM
pany. the Union oil company, the Cali
fornfa canneries' association the city
electric companies, the Sperry -four
company, the Palace hotel, the Fair
mont hotel and the st. Francis hotel.
Where efficiency, curtallment Of eX-
cessive labor costs. saving Of fuel and
little friction and noise are essentials,
these oil burning pump governors are
without comparison. They are revolu-
tionizing the worlds market for fuel,
and san Francisco is the great distrib-
uting point.
The governor is used for various pur-
poses. and owing to its sensitiveness is
adapted for automatically controlled oil
burners and other machines on which
a high grade governor is required.
Other pump governors are made in the
east, but they do not compare with this
local pump. for the reason that the
eastern machines do not offer the same
advantages in adjustment and efficiency.
The local machine will work on a va

.justed and works in any position This
feature appeals particularly to en-
gineers.
MANUFACTURED OF BRASS
The governors made locally are man
ufactured entirely Of brass and are
government gauged. The machine is
a double seated regrinding rebalance
valve. which is another point in its
favor over the eastern article. Con-
sisting entirely of brass the seat is
much better than if only brass lined,
as different liquids used in the latter
type will eventually work under the
seat, causing erosion and retarding the
running. In the governor there are
no blind stufing boxes, which is an
other advantage over the eastern make
as Il gives an opportunity to the en-
gineer to see and regulate the ad-
5usters to the proper running point
in the boxes.
VALVE EASILY ADJUSTED
The valve stem can be adjusted by
turning the head containing the dia-
phragm to right or left and can be regu-
lated by the fireman or any one else
in the absence of the engineer. The
desired pressure is obtained by adjust
ing set screw under the spring All
connections are fitted with extra heavy
ground joint unions. 1t can also be
used for a pressure reducing valve hav-
ing positive cutoff which is guaran-
teed TO be absolutely reliable For
graceful design, workmanship and reg
ulation there is no rival machine that
can compare with ii, as is testified to
by its universal use.
Besides the pump governors. the

pioneer in San Francisco in its line.
which has installed more oil plants
and burners than all competitors com

cern OF the kind in the world. makes a
speciality Of the Little Giant" and in
candescent improved oil burners.
At the present time the company esti-
mates 1000 in daily use throughout the
United States and foreign countries.
The burners have won out in more
than 1000 economy tests against other
burners and have made a saving of so
per cent over other burners for the
Stockton glass works, where four car
loads OF oil are used per week, saving
enough to pay for the burners in three
days. On the Southern Pacific com
pany boats they have made as high as
Z per cent saving, this record being ac-
complished on the largest steamer
burning crude oil on the Pacific coast.
On the largest ferry boat in the world.

coal, saving OF 6S per cent is remark
able, and further shows the possibilities
of California oil and San Francisco
