so Tor some time. The other furnaces are
reported banked owing to the idlenesS of the
rail mill, which is closed for repairs. AT
the works of the United States Iron and lin
Plate Company considerable experimenting
has lately been made in order to determine
the best method by which to manufacture
plates for commercial use.
AT the Duquesne Forge Company's works
two Stirling boilers, with an aggregate
horse power of 500, are being added. Me-
chanical stokers will be used. At the works
OF the Sterling Company, located near the
above works, a new boiler house has recently
been erected and a battery of four boilers
and other improvements made in order to
meet the increasing demand for the high
grade of steel manufactured by the company.
The Duquesue Tube Works have completed
ironclad additions to three departments
which will be used for asserting and storing
the various sizes of tubes, as we'll as increas-
ing the capacity of the plant, the sizes of
the additions being 751140 feet, S5x125 feet
and 50xSO feet.
An Increase of Capacity.
The Pennsylvania Tube Company, in
order TO enlarge their capacity for manu-
facture, are compelled to make use of their
old warehouse. A new warehouse 100x400
feet and built entirely Of iron, is now being
erected. At the drilling and fishing tool
works of Ireland & Hughes, on Twenty-first
street, the firm has just occupied their new
machine shops and offices. The additions to
the forge are about completed. A very
novel piece of mechanism is being used at
these shops. 1t is a movable steam hammer
patented by an employe of the firm. 1t
is operated by swing joint and can
be worked in any position and is
claimed it can do the work of three men,
The Walworth Manufacturing Company,
which recently occupied a portion of the
old Continental Tube Works out Second
avenue for the manufacture of metallic
telegraph and electric poles, but was COM
PEELED to remove when the old lease ex-
pired, is now erecting a building 36x136
feet in rear of the keystone mill to pursue
their former work.
AT the Edgar Thomson plant the inten-
ton OF the. firm to shut down on the 7th
inst, which was previously noted in THE
DISPATCH, did not go into effect until the
l4th inst, as it was necessary to wait a
week to complete an order Several very
important improvements will be made at
these works, the nature of which have pre-
Vionsly been fully described in these col
umnS. The improvements viii greatly in
crease the capacity of the works and enable
the firm to cheaper the cost OF produc-
tion, and will include three new 10
ton converters, new blooming mill, a
new rail mill engine, new chargers,
improved hydraulic machinery and 20 new
boilers which will be equipped with mechan-
lcal stokers. Among the furnaces, "E, ,"
I'D" and 'A'' are out for repairs, but the
other furnaces will continue in operation.
Sixteen new boilers. with the necessary
buildings and stacks, are being added to tie
steam plant and many additions are being
made to some Of the casting furnaces.
The Largest of Its Kind.
A. the Homestead Steel Works the work
of erecting the new 36-inch beam mill,
which will be the largest of its kind in the
world, is progressing rapidly. Mr.. J. A.
Potter. the superintendent of this plant, has
recently invented train of four high rolls
which will be used for rolling heavy armor
and other steel plates. The firm have award
ed the contract for the construction of the
rolls to Robinson, Rea & Co. The first and
fourth rolls are each 34x110.> while the Sec
ond and third or middle pair are of the same
length, but only half as heavy. The weight
of the four rolls exclusively is 20 tons, while
that of tine housings is 80 tons 1t is claimed
that while the small rolls do the rolling the
large rolls bear the immense pressure, that
the danger of breaking is not half so great
as in ordinary rolls, and even then the break
age must necessarily be in one of the two
small rolls.
Messrs. P. Barrow and j. J. Broderick,
puddlers at the American Iron Works OF
Jones & Laughlin, have applied for letters
patent on new pudding furnace. In the
new furnace one half is movable, and the
other half stationary. That part of the fur
mace in which the iron is to be melted re-
sembles cylinder and will revolve. It
IS bullt on standing platform.
and constructed to hold from
1,5o0 to 5000 POUNDS of iron. The
furnace in which the balling process is per-
formed Is very little different from the pres
ent style of furnace. The draught stack
will remain stationary, but all other parts
of the furnace including the fire box will be
moveablt. From the revolving furnace the
iron passes in semI-liquid state through a
conveying trough in the bottom to the ball
ing furnace. 1t is claimed that puddler
can turn out from seven to eight heats with
the new furnace in the same time that it
now requires to make five, and that there is
a saving of $500 per year on each furnace
over the present style of furnace.
Reports of New Industries.
1t is reported the Nimick & Co. have pur-
chased the Fairehance furnaces with the OBJ
ject of moving their mills to Fairchance.
