In the latest model Of the Stearns line
the Stearns-Knight, new type of motor
is used. The greatest feature Of this
motor Is the use of sliding sleeve valves
In place of the old style cam and spring
operated valves. This valve mechanism
was invented and patented by Charles Y
knight of Chicago, and is perhaps the
greatest development in automobile con-
struction since the use of pneumatic tires.
This principle OF valve operation had al
ready been adopted by Daimler in Eng
land, Mercedes in Germany. Panhard in
France and Minerva in Belgium.
This improvement In the design and
operation OF the valves has eliminated all
noise In this part of the mechanism Of a
gasoline motor. Valve action consists of
two concentric sleeves sliding UP and
down between the piston and cylinder
wallis These sleeves open and close wide
slots or ports opening directly into the
combustion chamber through which the
inlet and exhaust gases pass. These
sleeves are moved up and down by small
connecting rods from a crank or eccentric
shaft In about the same manner as the
slide valves Of a steam engine are operat-
ed. This shaft is driven by a silent chain
and the usual noise Of timing gears is
eliminated; Throughout the whole travel
or the valve their control and quietness
Is absolute. The old style valves were
lifted from their seats by a cam and
brought back again by a heavy spring.
Inc noise OF the cam striking the sleeves
when 1t started to lift and that Of the
valve striking it's seat when closed by the
spring cannot be eliminated. although
many more or less successful attempts
have been made to muffle this noise.
