with reasonable success. Certain
skcultles peculiar to that class of
N were overcome only after pro-
ced experiment, so that this par
Elar development is a distinctly
hlern one.
A is only after recognizing these
rs that one is in a position to appre-
,te the beauties Of the big air COM
,SsOr that has just been installed in
Isl Twenty-fourth street, New York,
.hinally for the American Air Pow
Company, but really for the Metro
btan Traction Comapny.
Eben power is stored for future use
compressing air it is higher pres
"a than that which Is used. The
bier the pressure the more work is
hnable from a given volume. Ac-
A.dngly. when any wholesale job,
running a heavy street car for sew
miles, is about to be performed, it
desirable to employ much greater
|sssure at least for storage purposes,
In in any of the other common APP
|'Ieations Of compressed air. The gas

a Producing valve"
mi the huge TASKS or bottles that
~ pEced under the cars to carry the
Impressed air are charged at the sta
inch or more. The compressor that
rgeS these TASKS and the stationary
|age tanks at the power house, then,
be capable of squeezing the air
n to about $500 or $500 pounds to
inch.
BE- plant just installed in West
nty-fourth street is exceptional in
L the first combination ever made
b engine of LOCO horse power with
compressor that develops $500
bis to the inch.
Be air compressor is an exact coun-
art of a steam engine. In the latter
pr, already under high pressure,
pes piston along and develops
Ter thereby. In compressor pow
Pom another source pushes the pis-
and thus squeeZes up air from n
to a high pressure. Just as the
lnSion Of steam is often divided
three or four stages, SO the COM
sion of air is usually effected by
ICES instead Of all at once. The
pressor has four cylinders. The
est has a diameter of 46 inches,
carries on the first part of the
The next has a diameter of "a
eS, the third one is IA inches across
the fourth only 6. But the pistons
ihem all have strokes of the same
th-60 inches.
