VERTICAL BOILER FEED PUMPS.
When men who manage manufacturing or other
industrial enterprises where pumps are required
find it necessary to purchase a modern pump, they
naturally investigate to determine which make of
pump will afford the best satisfaction for the
duty to which it is to be adopted. In general, as
with most other mechanical equipments, the
pump which combines the features of security,
durability and efficiency with economy in the cost
of maintenance, is the one which the buyer seeks.
There are many types of pumps, and there are
many combinations and adaptations of types of
pumps, and combinations and adaptations of steam
and water cylinders, that are possible for various
uses. But it is the intention here to refer to
that commonly used type of machine, the boiler
feed pump, the design and construction of which
do so much, when the pump is a successful one,
to add to the efficiency and satisfactory results
obtained from its use.
Men who have technical and engineering knowledge
of modern pumps are well aware that the
product of the A. S. Cameron Steam Pump works
is renowned for meeting all the conditions for
which they are designed and proportioned, and
there is scarcely any part of the world that could
be mentioned, where Cameron pumps are not in
satisfactory use. They are sent to districts so
remote from the ordinary transportation facilities,
in the farthermost corners of the world, that the
most primitive means of mule back carriage are
resorted to in conveying the various parts of their
sectionalized pumps to their destination, where
they are then set up.
For boiler feeding the company lists among
other types, the Cameron Vertical Boiler Feed
Pump—an illustration of which is presented herewith.
The photographic reproduction shows a
plain, unassuming vertical piston pump on base,
but where it is known its virtues are appreciated,
since it possesses every necessary attribute of a
perfect direct-acting pump, occupying but little
space and giving the maximum capacity. Although
shown on a base plate, it is sometimes preferred
for marine use to bolt the pump, by means of lugs
cast on the back, to the bulkhead. This has been
done in the case of pumps of this type furnished
to the smaller gun-boats and which have seen quite
active service in the United States navy. In common
with all Cameron pumps, no working part
is exposed except a small part of the rod, which
may also be covered, if necessary. The steam end
may be adapted to work any steam pressure, no
matter how high and the water end is fitted with
Cameron patent priming valves, and a removable
bushing or lining which may be taken out and
replaced with a new one in a few minutes, thus
avoiding any delay when it becomes necessary to
renew the working barrel of the cylinder on account
of wear. Those desirous of becoming further
acquainted with the facts relating to this
or any other type of pump made by the A. S. Cameron
Steam Pump Works, are invited to address
the main offices and plant at the foot of East
Twenty-third street. New York City, and ask for
pamphlet which will be forwarded at once.
Mr. John R. Marshall has resigned the general
superintendency of the Hostetter-Connellsville
