lance would be 1876 Tbs per ton. A

lance would be 1876 Tbs per ton. A
train 400 1876 =7S40; as the adj
hesion requires 5 times this amount
on the driving wheels to cause the
necessary friction between the wheels
and the rails to prevent the wheels
from slipping; thus 400 1876 II
1910 X 5 - $4,000 lbs, the total re-
sistance of the train.
A 16 inch cylinder has POI square
inches and locomotives in. tA",
cylinders. Suppose this to be the
hardest grade on line of road and
working at final steam pressure of
100 lbs per square inch on the pis-
tons; thus 2U1 X 10O=20.10 x2=I
1920 1bs-a little over the resis-
lance. This will be sufficient
force to keep this train running at
speed of 20 miles per hour-sup-
posed to be fed with cold water
When the top of the grade is
reached the demand ceases and the
lever adjusted to suit the line Of
road it has to run over.
AS the hot feed of The heater i
evaporates one quarter more water /
(steam) we have 125 lbs steam pres
sure on the same pistons to deal
with; thus 201 125 = ,125 q
50,25O lbs, being over the resistance
of 500 tons. Adhesive weight 49,
600 lbs.
Suppose the first train is divided
into 20 cars and move forward 20t
miles per hour by a force of 10000
Tbs how many of the same cars
would move at the same rate of
speed by force of 50,250 lbs; thus
% x 50,250 = 10000 = % cars.
If Figures are facts we add by the
hot water feed 5 cars to the train
worth $40 per car, swelling the in
come two hundred dollars a day to
each locomotive.
This brief explanation was not
intended for the purpose of explain
ing the full merits of the heater. | |
would intimate the object of fuel
and hot water feed for the safety of |
the boiler, life and property.
The amount of feed water esti-
mated at one pint is equivalent to
$40 gallons per hour. 1t must be !
remembered on working hard grades
three times more water, whether hot
or cold must be evaporated.
The draft of locomotive depends
entirely upon the quantity of ex-
haust steam forced through contrac-
ted pipes into the stack for vacuum
to excite the fire to generate steam.
The hot water feed generates one
quarter more steam. And at this
critical time of need climbing
grades) we utilize it first for energy,
and then to agitate violent draft to
increase the temperature in the
stack and capacity of the heater,
the harder the engine works. 1t is
thus the more steam is required the
more steam is produced, for all the
steam used in the engine is exhaus-
ted through the stack with great
force and aid, enveloping the heater,
drawing the air through the burning
fuel in its final escape to the open
atmosphere to stimulate the fire to
generate the requisite quantity of
steam.
By this increased evaportion and
improved draft the contracted pipes
can be enlarged diminishing back
pressure in rear of the plstons, con-
siderably adding to the capacity of
the engine the draft is regulated at
pleasure by the ash pan hampers. I
These heaters are inexpensive TO
manufacture and require but very
little care, as can be witnessed by
the Stationarys set up at various
places-one now in operation at the
Mineral Point Zinc Works above re-
ferred to.
This statement is not for the pur-
pose of advertising the heater, but
only to show where railroad COM
panies have as many as 700 loco
motives in operation what figures
will foot up 700 x 200 = 100000.
The enormous sum of one hundred
and forty thousand dollars income
per dag produced by hot water
feed for their boilers-
