speed that the consequent increased rapidity'
of the exhaust causes pressure from the ex-
haust stand. d to be applied to the front side
of the piston in the cylinder 83 through the
5 pipe 103 and such pressure moves the piston
rearwardly thereby causing it to correspond-
ingly actuate the rod 94, partly turn the bell
crank 98 and cause said bell crank through
the instrumentality of..the rod 67, arm 66,
10 .rock shaft 62, arm 64 and links 65 to open
the dampers of the. flash pan.against the re-
sistance of their springs and to hold said
dampers open while the engine is running,
thus furnishing an increased quantity of
15 air for combustion in the fire box. The
openings in the hollow fire bricks forming
part of the. lining of the fire-box furnish
sufficient air for combustion until the flash
pan dampers are open. In practice the
20 dampers will be automatically opened by
the action of the exhaust .steam from the
engines. when the locomotive has reached a
speed of approximately _10 miles per hour.
I have herein shown and described my ex-
25 haust steam actuated damper regulator as for
use on an oil burner locomotive where it will
be evident that the same may also be used in
connection with stationary steam boilers and
engines and for other like purposes and I
30 will have it understood that I will not limit
myself in this particular.
Having thus described my invention I
claim
1. An engine of the class described having
35 a fire box provided with an air inlet box,
dampers for said air inlet box, automatic
means to close the dampers when the engine
is standing, means actuated by the exhaust
and to open the dampers when the engine
o is running..
2. An engine of the class described having
a fire box provided with an air inlet box,dampers for said air inlet box and auto-
matically acting means to close the dampers
when the engine is standing and means to 4&
open the dampers when the engine is run-
ning, said damper opening means including
a fluid pressure operating mechanism con-
nected to and actuated by the exhaust.
3. An engine of the class described hay- 50
ing a fire box provided with an air inlet box,
dampers for said air inlet box, automatically
acting means to close the dampers when the
engine is standing and means to open the
dampers when the engine is running, said b5
damper . opening means including a fluid
pressure operating mechanism connected to
and actuated by the exhaust, and also in-
cluding counteracting springs to close the
dampers when said fluid pressure actuating 60
means is relieved of pressure.
4. In an engine, a fire box having an
air inlet box provided with dampers and
means to normally close the dampers, a cyl-
inder having a feed pipe connecting one end . 6
thereof to the exhaust nozzle stand of the en-
gine, said cylinder having a vent opening
in one side, a piston in the cylinder having
a sleeve open in the feed end of the cyl-
inder and also provided with an opening 70
adapted to register with said vent opening
when the piston is in one position, a piston
rod, and operating connections between the
piston rod and the dampers to open the lat-
ter when the piston is moved by the power 76
of the pressure of exhaust steam in the
nozzle stand.
In testimony whereof I affix my signature
in presence of two witnesses.
