placed in it's stead. In this door is
a trap door, curved inwards, with
steel plates at the side, against which
the curved part of the door fits When
coal is placed in the hopper, it covers
up the space in front of the door en-
tirely. The machine is then placed
in motion by thottle lever. Back
and forth plunges the ram" with
each stroke throwing open the trap
door, spraying the coal shot into the
fire box, over the entire fire surface.
Air Kept From Fire Box.
AS will be readily seen from this
description, not one bit of outside air
is allowed to get into the fire box, in
this way keeping the temperature
within the box always at an even heat.
The saving in fuel at once becomes
apparent. The even temperature thus
maintained Is greatly effective in
lengthening the age of usefulness Of
the boilers
AS the machine was originally con-
structed the coal was to be placed IN
the hopper by the fireman, but now
conveyor has been devised which
runs through the tender, scraping out
the coal of its own accord and carry
ing it into the hopper, thus making
the entire machine automatic.
However as previously stated, it is
not the mere saving of fuel and Of
boilers, which gives the great signifi-
canoe to the stoker. Every railroad
man knows that the roads of the Unit
| ed States would build larger engines

| that would be put upon the fireman. 1t
is almost impossible now for the firemen
to keep the engines of the present gil
gantic size supplied with coal.
Will Do Work of Five Men.
| The new invention will easily throw
| five times the amount of coal into an
| engine that any man could do, and
again the amount of coal required with
the machine at work is much less. The
possibilities that this device gives to
the engine builder are SO great as to
stagger the thinking man. To illus
trate, one should notice the next mon
| ster engine such as are in use on some
of the local roads, that he happens to
be near. Consider its massive proper
lions and its wonderful strength. Think
that the size is limited by the limit Of
human endurance. Then remember that
| by the workings Of this new machine,
| that limit may be increased by five
| times or more, and ask this question
What will be the result?'
Can Place Coal as Desired.
The stoker does not work continu-
ously, but only as it Is needed to keep
the engine in coal. A device govern
| plunger, controls the placing of the
coal. If the engine burns its coal fast
est at the front of the fire box, the
plunger is kept going at full length
stroke and thus the most of the
coal is thrown to the front of the box
If the coal burns most rapidly, at the
middle at the break of the CRATES as it is
called. the plunger Is kept going at a
two thirds stroke, throwing most OF
the coal in the center of the box and
scattering the remainder before and
book of the center.
Again, if the coal is consumed more
rapidly in the front of the fire box
the plunger works at half stroke
spraying a lesser amount of coal for
ward, but placing most of the load
carried by the stroke in the part near
est the door.
/! A foot lever placed on the outside OF
the hopper allows the fireman to opes
the trap door and look within the fire

! but it is stated that after the fireman
becomes acquainted with the vagaries
of his engine he will know just how
to place his COAL without looking into
the box
Speed is Enormous.
When it is considered that the ram
or plunger can be made to make 2O(
strokes a minute, a slight diea of the
amount Of coal it would be possible t.
throw into an engine by the means o.
the stoker can be gained.
While the saving effected by the
stoker is not it's greatest feature, new.
ertheless it is an item not to be des.
pissed. While it is said that the test.
of the stoker have proven that it will

that if it will but save half a ton pei
