Port Henry.

| SACEs.
During the past two years there has been
constructed on the banks of Lake Cham
plain, near the Port Henry Iron mines, by
the Cedar Point iron company furnaces
that in point Of workmanship and complete
ness of details for the manufacture Of iron
are second to none in the country. In ad
dition to these the Crown Point iron COM
pany have also erected furnaces descrip-
ton of which has already appeared in our
columns, and in this article we propose
giving an account of the new furnaces at
Port Henry.
on which the furnace now stands was for
merly covered with water, it being decs
enough to float lake boats, owing to its
proximity TO the New York and Canada
Railroad, and also from the easy manner
in which boats could be loaded from it,
the place was selectee as being the most
convenient on which to build, and prepar-
atoms were accordingly made for that pur-
pose, and today the furnace stands COM
pleted, perfect in all its arrangements,
noble monument to those who designed and
superintendent its construction. Under the
stack has been laid in cement stone work
to the depth of forty feet and on top Of this
FIRE brick have been placed to the height
of five feet. Under the ovens is thirty-five
feet of stone work, under the elevator rest.
ing upon piles is solid mason work thirty
feet in depth. All of these foundations
with the exception of portion of the elc
vator house, and the engine room rests up
on solid rock, thus making Il foundation
that will last for many years In the con-
struction of the foundations 81 900 perches
used.
| THE STACK
is seventy feet in hcighth by twenty-seven
feet in diameter. 1t is lined with ire proof
brick sixteen feet in the boshes and thirteen
and one half feet in the tunnel head 1t
is closed with a bell and hopper, the bell
being sever feet in diameter which is raised
and lowered by pneumatic cylinder. The
furnace will be blown by six troyers. For
the purpose of supplying the plant with ore
it is provided with one pneumatic elevator
the cylinder being three feet in diameter,
seveaty-two feet stroke, made at the cele-
brated Delemater iron works. The plat
| foro ~; 10, oh IN,
supply all the ore necessary, its capacity
being seven tons at a single lift.
THE CASTING HOUSE
is built of brick, 70xG0 feet 81 feet TO the
caves, with galvanized iron roof. The
furnace has four OF the Withcreil fire brick
hot blast stoves. These are the first ever
erected in this section of the country, but
in other sections are coming into quite gen.
eral use, and by many are considered the
best made. These stoves are 30 feet
high and % feet in diameter, and con-
tain 500 tons of fire brick each, and
have a heating surface of 1900 square
feet each. They are capable of read
lily heating the blast to 1000 degrees
and even higher if the gas could be
procured. All the pipes conducting the
hot air from these stoves to the furnaces
are lined with fine brick from TO IA inches
thick. The furnace will be worked with q
closed front it having chimney the same
size and height as the one connected with
the boiler. The hot gas is brought from
tie tunnel head in wrought iron pipes feet
inches in diameter, which carries the gas
to the hot blast stoves and the boiler. From
flues each feet in diameter connect these
pipes to the boiler and one fiue four feet il
diameter branches from the large pipe tax
ing the gas to the stoves. The large fue,
feet 8 inches in dirmeter sustains a spiral
stairway by which the tunnel head is
reached.
THE BOILER ROOM
is of brick 72x66 feet covered with an iron
roof. 1t contains eight plain cylinder boil
ers each SO feet in length and feet in di-
ameter. These are connected together in
pairs so that any one pair or more can be
used in case of necessity without regard
to the others. Each two boilers are pro
yided with mud drum 10 l-2 feet long, ;
feet in diameter, connected with them also
is steam drum feet long, by 4 feet il
diameter; all the iron used in the construc
ton of the boilers being 3-S of an inch il
thickness, and were constructed by Thoma,
Sutherland of Troy, who also furnished al
the wrought iron work used about the fur
mace.
Each of the boilers are provided will
CRATES so that in case the supply Of hea
from the gases should fail they can be read
lily heated by fire. The main steam pipe
leading from the boilers are is inches II
diameter and 105 feet long. These pipe
being connected with the drums by cop
per pipe, and each pair of boilers are sup
piled with one G inch, Richardson's safet,
valve. Each gang of boilers are supported
by cast iron columns each gang being pro
vided with II beams, each beam being l.
inches deep. These beams rest upon col
} umns, the boilers being suspended from
them For the purpose of draft these boil
ers are connected with one wrought iroi
/. chimney 1l5 feet in height.
THE ENGINE ROOM
is also of brick 60xG6 feet, (under it is
basement l2 feet high) this structure is 3
feet high and also covered with galvanize
: iron roof The engine is a side lever con
densing engine, 1900 horse power, and wa
made by II. G. Morris of the celebrate
Southworch foundry, Philadelphia. Tn
steam cylinder is GO inches in diameter, an
d 8 foot stroke, the blowing cylinder bein
