per minute, and when steam was supplied from old boiler plant
pressure was 65 pounds. The following were taken from indicator
tests made under the foregoing circumstances with the breaker
running empty and the run-of-mine conveyor thrown in. The engines
developed 150 horse power, and the speed of the run-of-mine
conveyor was 17 flights, or 68 feet per minute. With eight cars of
coal in the drag, the breaker preparing two cars per minute, the
engines developed 236 horse power.
The breaker is heated by steam and supplied with incandescent and
enclosed arc electric lights throughout.
The steam plant, which furnishes not only the steam required to
operate the breaker, but also the various hoisting engines, pumps,
fans, etc., scattered all over the property, consists of a frame building
50x106 feet, equipped with ten horizontal return tubular
boilers, 72 inches x 18 feet, made by the Vulcan Iron Works, Wilkesllarre,
Pa., with 76 4-inch tubes, each boiler representing 150 horse
power, or a total of 1,500 horse power. The boilers are set in pairs
and are connected to a 16-inch steam line, and operated by forced
draft, a
6x9-foot right-hand, down-discharge Sturtevant fan delivering
the air to a conduit which carries it under and back of the
ash pits. A large space running the entire length of the boiler room,
under the floor and between the wall at the front of the boilers and
another wall parallel to the same, permits the loading of ashes
directly into the cars, where it is run to the entrance, or side, of
the boiler room and hoisted directly to the ash dump. An annex,
29x20 feet, at the rear of the boiler room has been provided for
the Sturtevant fan. A Warren, Webster & Co. 1,500-korse power
feed water heater and purifier, a fan engine and two Jeanesville
feed pumps are also stationed in this annex. The water for the
colliery is obtained from a well on the southern part of the tract,
a distance of more than 4,000 feet, and across a ridge, and is pumped
from the well to a reservoir located on top of the ridge 101 feet,
vertical height, above the well from which it is delivered to the
boilers by gravity, by a Halsey pneumatic pump, with a cylinder
24x28 inches, with a capacity of 150 gallons per minute. The air
is carried from the compressor, which is operated near the boiler
room, through 2^-inch pipes to the pump, which requires no attendant,
starting and stopping as the compressor is
started and stopped
at the boiler plant. The water is pumped and run to the boilers
through a 5-inch pipe, which also supplies the village on the property.
Steam pipe lines have been erected and extended to the various
hoisting engines, pumps, etc., on the property, from this boiler
plant, of a total length of 16,338 feet, from 10 inches to 2 inches in
diameter, and which is,
with the exception of a very small portion
connecting pumps, etc., carried on posts over the surface.
