the revolving barrel. This outer open
Ing is In the front Of the gun.
As the projectile moves out through
the gun barrel the barrel itself Is ron
tinuinS Its rotary movement. The
force and speed with which the ball
leaves the gun. therefore, Is the re-
sultant of two forces, its radlal force
acquired by Its motion out through
the barrel and the peripheral force,
which is the force acquired from be-
Ing rotated about the shaft at n ate
of $50 feet a second.
When the muzzle of the gun barrel
has lust reached the opening in front
the ball, due to the timing device
which let it into the barrel at Just the
proper point In It's revolution, Is at
the end of the barrel and ready to fly
out in a straight line with the force
acquired from its centrifugal motion.
For each revolution OF the gun barrel
q single p~rojectile Is automatically fed
into the breech block at a definite
point of the r%otatlonal movement, n
is released from the b~reech-bloek ana
permitted to enter the barrel at an
other equally definite point Of the ro-
rational movement.
1000 Shots a Minute.
The centrifugal gun, according to
the tests just made by the war de-
partment, Is capable of firing about
1000 balls q minute. When 1t Is de-
sired to cease firing the feed from
the hopper is shut of, stopping the
flow of balis into the breech-block.
Then the motor is stopped. Other
wise the balls would continue to be
elected at a decreasing range as the
motor slowed down.
The hopper Is n patented container
with a revolving bottom itted with
grooves. AS the machine gunner turns
a crank or handle the balls are ground
one by one into a tube which leads to
the breech-bleck. Instead of grinding
them out by hand, the same power
that operates the gun may be utilized
to drive the mechanism OF the hop
per.
As now designed two men can carry
the machine aud tripod. and two moro
men can transport the batteries.
"Fire control with our gun Is con-
slant" said Mr.. Moore. "There Is no
smoke, noise or fash. Instead OF e
900 men being exposed TO enemy nrs
and covering much ground and area.
less men than make mp one squad
would be used In operating our gun.
and the Gre control would come from
one central point. Distributing our
guns ct certain intervals would cover
an enoruous front line. The lack OF
fire or noiss from our gun conceais
the position Of the same and prevents
the enemy from s~scertainins its 10.

Ii Is a well known fact that bullets
fred from a gun held rigid viii not
all strike Ina the same place, but win
show n lateral and vertical spread.
Mr.. Moore has figured that the lateral
spread of q ball from the centrifugal
gun Is approximately five feet for each
hundred feet that the ball travels. and
the vertical spread three feet for each
hundred feet. Thus. at a distance OF
300 feet the centrifugal gun would
cover a street Is feet wide for a dis
lance OF nine feet above the ground.
at the rate of 1000 shots a minute.
thereby rendering anybody's chances
OF remaining alive In that area II
ceedingly slim. The territory that
could be covered by the gun without
aiming It increases correspondingly as
the range Is Increased.
Major Moore explained that he felt
free TO discuss the mechanism and
principles &C the gun because the re-
~strictions placed upon him not 10 re-
veal or discuss any details connected
with the gun have recently been lifted
by the war department.
