Submitted to the War Department
just Before Armlstice Was Signed.
Ever since the publication of a brief
dispatch from Washington q few days
ago to the effect that the war depart
ment was experimenting with q new
type of noiseless machine gun that
substituted centrifugal force for pow
der as a propelling power Edward
Thomas Moore, IN attorney OF New
York. has been receiving letters from
friends asking him IL the gun which Is
being experimental with now Isn't the
same one that he invented and sub
mitted to the war department a few
weeks before the armistice was signed.
To a World reporter Mr.. Moore not
only admitted that the gun was his In
vention, but offered to explain its prin-
ciple. For several years prior to the
war Mr.. Moore, who lives In P~assaic,
N. J., was a major and judge advocate
In the New Jersey National Guard by
appointment of Woodrow Wilson as
governor of New Jersey. When the
United States entered the war Major
Moore was pressed into service by tll
war department and assigned to New
Jersey as inspector of the draft In
that state. His invention OF tho
Moore centrifugal gun" for which
he and Saul Singer Of Cedarsburg. l..
l.. obtained patents. was offered to the
war department shortly before the
signing Of the armistlce. The cessa-
tion Of hostilities delayed experiments
with the gun. but Major Moore left the
invention with the bureau OF stand
ards Tor further tests.
"Oavid Up to Date"
Mr.. Moore says that the Biblical
story Of David Staying Goliath with q
stene which he whirled around his
head in q sling gave him the idea Of
applying centrifugal force TO the OPP
Grafton Of q machine gun. Bringing
David up TO date Is the way he de-
scribed 1t.
There have been other attempts to
invent a centrifugal gun. Mr.. Moore
does not claim to have originated the
idea. He says the French. tho Rus
SLAMS and the japanese have expert
mented with centrifugal guns from
time to time, but were never success
full because OF fhelr failure to control
the dispersion Of the bullets. From
the tests which MFR. Moore conducted
for the war department and those now
being conducted, II would seem that
Mr.. Moore's claim TO fame lies In hav-
ing invented the first practical centrif-
ugal gun.
Control Of the Bullets.
In the gun which Mr.. Moore hns In
vented complete control Is obtained
over the dispersion of the bullets by a
special patented timing device which
feeds the balls into the gun barrel of
a regular rate and elects them at reg
ular intervals and from the same
opening. According to Mr.. Moore, the

Bile of firing a ball a mile and a half
and killing a man at that distance;
also that a ball fired from the muzzle
Of the gun a short distance away has
penetrated seven thicknesses OF heavy
planking. which he says Is one thick
ness more than a bullet from any
army As Colt will penetrate.
Centrifugal force is nothing more
than the tendency which objects have

idly revolved about a fixed center. The
most common utilization OF centrifu-
gal force. is In the modern cream
separator.
Several Problems.
In seeking 70 apply centrifugal force
to a machine gun. however, Mr.. Moore
was confronted with several prob
lens. In the first place, In order to
get sufficient force TO propel q ball
$50 feet a second. which Is the speed
of a bullet from n Colt automatic, sew
eral thousand revolutions OF the gun
barrel a second had to be obtained.
This necessitated the construction OF
"A special type of electric motor TO pro
vide the requisite revolutions. Then
the tensile strength OF the metals en-
tering into the composition OF the gun,
and particularly of Me barrel. had to
be considered. Mr.. Moore's knowledge
OF electric motors, tensile strength OF
metals and OF ballistics being limited.
he consulted experts In those various
lines. and assembled the information
collected from these various sources
before starting to construct the cen
trifugal gun.
The main parts OF the gun as de-
signed by Mr.. Moore consist Of an up
right shaft attached to a powerful
electric motor capable OF giving II q
rotation OF 10000 revolutions a min
ute. Attached to the shaft, and at
right angles to 1t. 10 a hollow steel arm
