The Pelton Water-wheel Company has
Star mine of Grass Valley, Cal, of such
extraordinary dimensions that a brief
description will be of interest.
This wheel is Is feet in diameter, weighs
10,500 pounds, and is to develop $50 horse
power, running under $50 feet head at 10
revolutions, and is to be directly connected
to the shaft of a Rix duplex compressor,
capacity. The design of the wheel is
original and wholly novel. From cast-iron
hub radiate "a steel spokes, which are con-
nected to rim made up of angle iron prop
erly shaped, having a slot for the buckets
which are bolted to the periphery, the
strain being taken by four heavy steel
truss rods. The wheel is made of this
large diameter for the purpose of giving
proper speed to the compressor under the
high head available. The water power is
applied to the wheel through a variable
nozzle controlled by an automatic regu-
lator, which will maintain a uniform speed
on the wheel, with a variation from full
load down to Is per cent of same, affording
by this means the greatest possible econ
omy of water. The power thus furnished
is to be carried to the mine of the North
Star Company, some 1000 feet from the
power station, to run hosting works, mill
and other machinery connected with the
operations of that company.
