cap, II feet in height, of which feet
is to go underground and 8 feet above.
They are on an average 92s on the in
ner diameter and PA inches thick
through. The stem itself is over s
feet. The outer diameter is 11Ns inches.
SPECIAL TOOLS NEEDED
Special tools were needed to com
plete this job, and the iron works Sc
cured these at an expense of $4,000.
One of the bolt hole boring lathes will
bore through 2A inches of iron, "a
holes at one time, in three minutes
automatically. At the same time an
other machine, automatically arranged,
will make rims and screw threads,
the former varying. from one
tthousandth part of an inch to a quar-
ter of an inch, thus saving time and
labor. With these tools the hydrants
will be finished four months ahead of
I the time the contract calls for.
! The contract for the construction
of the hydrants is only one of several
1 large jobs the iron works is working.
/ on at present. One of these is a $780,
600 contract for the casting of differ
ent pieces of machinery for the Nicho
! las syndicate of California, a job that
was taken almost out of the grasp of
! large eastern firm, and the construc-
ton of $4,000 worth of shafting for the
Tonopah Extension company of Ne
vada.
The constant cry of the Union iron
works is for some government aid to
the American merchant marine, and II
this can be secured San Francisco will
have a concern ready, willing and able
TO handle the construction of any sort
of ship that floats the sea-
PATENT STEAM DRIERS
The Hageman & Broderson company's
patent steam driers are another prod
uct of San Francisco brain and en-
ergy that is finding market all over
the world The John Callahan COM
pany, agents for Ed c. Garrett & Co.
of 80 BeaIe street, has the agency for
these devices throughout the United
States and every day orders from all
over the country are coming in, as the
efficiency of the driers becomes known
to engineers. The greatest question
of present day engineering has been
stated to be that of economy, and an
aid in this that will not diminish the
volume of business has been found in
this San Francisco product.
For the development of the highest
efficiency of steam, as used in an en-
CINE, means for eliminating moisture
must be employed, hence in many
boilers. stationary, locomotive and
marine. there has been installed, at
considerable J expense, so called dry
pipes separators, etc, which to GER
tain extent prevent water going over
with the steam, but in no case actually
prevent priming; some of these even
go so far as to retard the flow OF steam
and cause it to be wire drawn, which
greatly reduces the efficiency of the
boiler and engine.
In the IL & B. steam drier is found
an apparatus which has met with the
requirements of the day and is highly
Endorsed by those who have used it.

mechanically by the current of steam to
gravitate before reaching the steam
pipe. 1t saves the necessity of using
/ other methods to prevent priming,
which not only has tendency TO de-
stroy the life of boiler and its con-
I Meeting parts, such as joints, valves,
hacking, etc. but will cause pitting TO
the destruction of tubes and other parts
and the continuous expense of such an
article viii amount to many times more
than the cost of the drier, to say
nothing of dhe immense saving in fuel,
boiler work and other expense attached
to the operation of a plant.
One of the chief advantages of the
IL &. b. steam drier is its simplicity:
it requires no attention: once it is in
stalled it will outlast the life of any
boiler. as it has no working parts to
get out of order.
PACIFIC COAST INVENTION
The Hageman Broderson patented
steam drier is really a steam separator
applied to the inside of boiler directly
under the main stop valve 1t is the
Invention of Hageman & Broderson,
who are both practical marine engin
GERS on the Pacific coast, where this
apparatus has met with excellent sue
cess. being installed on several ships
that were noted for their extremely wet
steam conditions.
This apparatus is adapted to and built
for all types of boilers, but is particu-
larly recommended for marine work. 1t
allows water drawn up mechanically
bv the current of steam to gravitate
before reaching the steam pipe. 1t
occupies a very small space and re-
ouires no attention. 1t has no work
ing parts to get out of order
The steam does not pass through any
choxed openings or wire gauZe, but has
the benefit of the full area of steam
nine and does away with dry pipes,
etc and in many cases has taken the
place of steam domes.
A general idea may be given of the
III e 3 steam drier. 1t is fastened
to the shell of the boiler directly under
the main stop valve and held in posi-
tion nv four small studs The steam
is caused to pass through a series of
mines or bands and in so doing passes
Arough the different areas, which
changes the velocity. but in no way
retards the flow.
