i
steam and furnishing power, with bat
terry of boilers centrally located, and the
steam distributed through underground
pipes, is so comparatively new that it can
scarcely be said to have attracted general
attention. 1t is nevertheless fact that
steam is being successfully used in many
cities already in this manner, and the
plan is gaining adherents rapidly. AT the
outset the work was more or less crude
but great improvements have been made
since it was originally begun. 1t is prob
able that few years hence what now
seems very satisfactory will prove to be
crude as compared with what will then
be in vogue. In Denver, Dubuque, Mil
waukee, Lockport, n Y, and
various other cities the ap-
plication of steam IN this manner
has proved success, and St. Paul can be
added to the list where, on moderate
scale, it is in practical operation. st. Paul,
too, has the advantage over other cities,
in that she has the inventor of the only
practical process for applying steam IN
this manner. Mr. Z. T. Osborne of this
city began getting patents for this work
ten years ago. He now has eighteen pat
one claims. One of Mr.. OsbOrne's patents
enables him to tap street main for re-
pairs when full head of steam is on.
This enables repairs to be made without
interfering with the consumers, except at
the exact point where the difficulty oc-
ours. He will also be able to supply steam
for five engines, enabling them to render
service more promptly than by

H. NJ. Carpenter, of the paper
house of Averill, Russell s. Carpenter, is
interested with Mr Osborne in the own
ership of these patents 1t has required
several thousand dollars to secure them,
but 1t can Justly be said that no town or
city can distribute steam through its
Osborne's patents. The royalty promises
TO yield the inventor, in % short time, an
income which will prove handsome
fortune annually.
The following is brief synopsis of Os
borne's patent duplex system of heating
for cities and towns by steam:
First--This system, as It's name implies, is
composed of two or more distinct circulations,
one the main or street system, and the others
the local OF house system. The local or
house system, is subdivided into public build
ing system, business block system and resi-
dence system; each system having its own
peculiar appliances, adapted for its own re-
guirements, each system being entirely indie
pendent and distinct from the other
Second-All the water of condensation is
returned directly to the boiler, and the con
sumner has no connection or control OF the
main cirCulatory system.
Third-Heat only is furnished. The con-
sumner can use it for any purpose desired, eth
er for heating, cooking or power. or all, as the
case may be.
Fourth-The street system and its connec-
ton are subject at will to any desirable and
nearly constant pressure, and the consumer
takes any quantity of heat required and uses
it i'll any shape or for any purpose desired,
carrying on its own apparatus, either high or
low pressure,as circumstances may require.
Fifth-The quantity of heat furnished to
any one or more parties is accurately measured,
and the measurement recorded in dollars and
cents and the meter is at all times open for in
specton by both furnisher and consumer, but
is beyond being tampered with by either party,
and the accuracy of the meter can be tested at
any time.
Sixth-All the water is returned back into
the boiler at high temperature, thereby over
coming two highly important and detrimental
objections so common i'll all other systems:
First, no wastage in water; second, large
saving in fuel, thereby reducing the expense
of both water and fuel very materially. The
water being returned to the boiler at high
temperature, the boiler being free from lime
and scale, the capacity of the boiler increased
and the outlay for boiler plant largely reduced,
and for the same reason, the life of the boiler
is very much increased and the cost of repairs
very much reduced.
Seventh-In this system the main return
pipe may be used as steam pipe for summer
use, or while the main steam pipe is being re-
paired, altered or changed, also in case of
break in the main steam pipe from any cause
whatever, the return main can be used as by
pass, and the supply of steam continued, and
only so much of the steam main as may be
disabled would be thrown out of use tempor-
arily.
Eighth-1his system having been brought
to its present state of perfection by an nengineer
who for many years has been wholly engaged
in the steam cheating business, and being famil-
lar with all the requirements thereof, has all
the details carefully wrought out not only to
meet the most advanced state of the art in ac-
complishing this most economical and scien-
tific result, but the details of manufacture and
distinct cost of special parts, and the construc-
ton of the apparatus are likewise carefully at
tended to. A few of the details are named below,
to-wit: In construction, arrangement, mode
for attachment to the main in any place with
out the expense of valves, and the attachment
can DC InhuC ut any Llllle UtLn OF Without lne
pressure on the main, or without hindrance to
consumer.
Any section of main can be shut off at any
time without the use of large and expensive
valves.
The expansion joints are very simple, easily
made, on general fitting, and can be packed
at any time without shutting off steam from
the main. This is a very important matter.
When the small supply of feed water re-
guired is taken from city main, the entire
street system together with the boilers is
automatic. Fuel being added to keep the fire
up, the height of water in the boiler, or in
other words the water line thereof is its own
regulator. The only water to be supplied to
the boiler is that which is lost by various
small leakages that may occur.
Mr.. Osborne has numerous testimonials
from practical engineers approving his
plans as noted above. They especially
commend the meter by which the con-
sumner is able to determine exactly what
amount Of heat he consumes. The con-
sumer can regulate his consumption at
will or according to his necessities. He
can heat one room or whole building,
as the case may be, regulating it as
readily as gas is controlled by
lighting greater or less
