The subject of water circulation within
steam boilers has become one of vital i'm
portance with manufacturers and steam
users. The duration, or life, of a boiler
largely depends upon its construction with
a view TO the dimensions of the water spaces
around the heating surfaces; also to other
obstruction which might impede the circu-
lation, leaving the impurities to be precip-
itated upon the heating surfaces. causing
scale or incrustation.
All natural water found upon the surface
of the earth, evaporated to dryness, leaves
always visible residue containing QUAINT.
ties OF earthly or saline matter, which have
been dissolved from the rocks and soil:
hence when evaporated within boiler the
water becomes highly impregnated with
these salts, which are rapidly accumulated
and deposited upon the heating surfaces.
greatly deterlorating the steaming Quail
tiles.
Scale has been found to be an Indifferent
conductor of heat to such an extent that
tubes made OF copper, brass and iron, the
conducting power of which are "a, "a and
II, respectively, when clean, show no per-
cepuble difference in their eyaporatiye
power after few days use with ordinary
impurified water
The only known method to obviate this
condition is to cause a circulation of the
water within the boiler, thereby causing
the lighter foreign matter in the circulation
and depositing it, together with the heav-
Ter, IN the leg OF the boiler to be disposed
OF through the blow-off cocks.
If bo of ia,
the inventor conceived the idea which is
herewith presented. 1t has passed from
the ideal TO the practical, and is now in
successful operation on the Southern Pa
citc system, fully demonstrating its eff
cheney. It's action is as follows: The
water passes through the iniectors, enters
the forward end, or smoke-arch, thence
through the forward flue-sheet and under
a copper diaphragm, running back to the
tire-box, slightly turning downward into
the water space.
An indirect current is established draw
ing the water from the main body in the
boiler under the diaphragm, causing q
complete circulation throughout the entire
boiler.
By reason of the circulation an even tenn
pereture is maintained through all parts
of the boiler, which prevents an UNEQUAL
degree OF contraction and expansion, which
Is very detrimental TO the shell and the
| numerous stay-bolts. The steaming quail
ties of boiler are also improved, requir-
Ing reduced consumption of fuel The
| necessity for frequent washings of the
boiler is also obviated.
The invention is attracting great deal
OF attention from leading mechanics
throughout the country, as it is new de-
parture from the common usage, and one
which bids fair to become quite general.
The application of Mr.. Jor6an's inven-
ton 70 locomotive boilers will readily be
understood by mechanics, and especially
by engineers-both of locomotives and
stationary boilers. While it is readily APP
plicable to the latter, it can, by slight mod
ification, be applied 10 all boilers, As he
fore stated, the invention is in successftl
operation by the Southern Pacific Com
pany, and the inventor is almost daily ip
receipt of letters from the Master Me
chanics of other railroads and engineers
making inquiry about it.
Mr.. Jordan is an old resident of this city.
| and veteran of the war, having at one
| time served on the staff of General Hawley
| of Connecticut. He is an experienced en-
gineer, and one of those intelligent me.
| chanics whose minds are ever active in the
| study OF mechanical appliances and i'm.
provements.
TWO MORE SUCCESSFUL INVENTORS.

to II. o. Beatty of this city, for a steam
