lMcresAfOnt Keely's Mighty Motor.

The New York San has the follow
ing A iSan reporter paid a visit to the
machine shop of Messrs. Sergeant &
Chillingworth, in this city, where one
of the keely motor generators is being
made.S 1t is intended to be of 100-horse
power, but by operating it rapidly it
will give it power of 800 horses. Its
height will be about seven and a half
feet. At present the parts are either
lying completed on the floor or in pro-
cess OF preparation. Among the former
is bed OF cast iron, seven and half
feet long and three feet seven inches
vide, upon which the superstructure Of
chambers and their accessory tubes will
be raised. The chambers are about
two feet in diameter, and vary in height
from two to two and half feet. They
are of massive steel, and their hollows
vary'from four 10 six inches in diane
ter, leaving the walls necessarily OF very
great thickness and capable of bearing
an enormous pressure. The difficulty
has hitherto been in obtaining metal
which would retain the vapor. ~
Experiments with a generator of
about 50-horse power on low pressure
gave entire satisfaction to the company,
and Mr.. Keely was advised to construct
larger machine. He, therefore, two
years ago, began one of 1,000-horse
power, to be endowed with sufficient
Strength to stand the requisite force
with perfect safety. The next expert
ment was with a generator of 1000
horse power, constructed of gun-metal.
A pressure of 6, 6,000pounds to the square
inch did not burst this metal, but
caused the yapot to oOze completely
through It's pores, much to the astonish-
ment of the bystanders.
This gun metal was of the best COM
position used, and comprised 80 per
cent. of copper, IA per cent. of tin, and
the rest of lead and zinc. 1t was then
thought that phOsphor bronze would
answer, the purpose, but the vapor
oozed through that at still less pres
sure. The virtues of wrought iron and
steel are now to be tried. The cham
bers of Mr.. Keely's 1,000-horse genera
tor in Philadelphia have stood press
ure of %, 800 pounds to the square inch
in the lower part, and 10000 pounds in
the upper, and retained the vapor, but
small globe at the top of one of them,
which, it was thought, could be safely
constructed of gun metal, allowed the
vapor to escape. A new one is under
construction, together with some minor
parts, and by June l a trial will'proba-
bly, be made, and one small machine
of 5-horse power will likewise be tried.
The chambers have stood a pressure
of 10000 pounds. The inventor and
the stockholders are perfectly satisfied
with the feasibility of the theory. The
only point now Is to get metal sufficient
ly dense to retain pressure.
Whsn it is considered that machines
driven by steam rarely or never create
a pressure of over 200 pounds to the
square inch, the enormous force of the
Keely motor, and its immense capacity
for propulsion, can be realized. The
power will be generated by a vaporiz
ing of water mechanically, and without
the agency of heat. The expense of fue
will thus be saved. Those interested
claim to have been misunderstood il
saying that pint of water only would
be needed for the propulsion of a train
of cars between this city and Philadel
phia and back. They meant that i.
five gallons were used for: an engine O-
100-horse power, a pint only might be
lost by yaporization through the pores
of the metal. None at all might. be lost
The water, after being vapOrized, anC
passing through the various tubes ant
chambers, does its allotted work upor
the engine, is reeondensed into it
former state, and, again becoming vap
orized, starts again upon its mission o
mighty pressure.
The capital stock of the Keely MOto
Company is S1,O00,000, divided int
20, 900 shares. Many shareholders, dis
heartened at the repeated failures, ant
the adverse comments of scientific men
have sold out at heavy loss, but other
are hopeful. 80 -
