GATLlNG'S INVENTION.
A New and, II Successful. Priceless Method
Of Casting Heavy Guns.

n New ana, III successful, Priceless Method
Casting Heavy Guns.
DIR. X. j. Gatling, the inventor OF
the gun which bears his name, and
which has been In use In nearly every
country which uses the arms OF modern
civilization In It's warfare, has invent
ed a new method Of making heavy
ordnance, wlech. it is claimed by his
friends. IL calculated 10 rcvolutioniZe
the gun-making industry of the world.
One or two attempts have been made
In this country 10 east guns OF solid
steel, and bore them out aftcrward,
but they have been practically steel
ingots bored out, and none OF them
have yet been shown 10 be sufficiently
perfect 10 meet the requirements which
heavy ordnance should fulfill. DR..
Gatling's invention, which is already
patented In this and several other
countries, consists In making guns
cast from the highest grade OF steel,
In such manner as 10 shape around
IA central core which is formed by tho
casting instead of being left TO tho
work of the borer, and this central
core is utilized for the purpose of cool
ing the casting from the interior out
ward before the exterior cools, rs IN
the ordinary gun casting. BY tho
new process DR.. Gatling makes
the metal cool gradually on
tho inside from the surface OF the
core, while the outside OF the casting is
kept at IA high temperatures The
metal Is thus forged, so TO speak, by
its own action from tho interior out
wardly, and tho creation OF IA hard, re-
sisting arch on the exterior of tho
casting, at which point the full forco
OF the high power exercised by tho
exploding ingredients within the gun
oxerts itself, Is thus avoided. or
course the method by which DIR. CAT
ling secures the cooling OF the gun
from the core outwardly is, for tho
present, his own secret, but il IL IL as
effective and practicable rs he claims,
and his friends believe, IL seems likely
90 work IA wonderful change In tho
The old way of making guns used
by Krupp, Armstrong and other IA
nous manufacturers Of ordnance Is
based on the building-up plan. The
gun is cast in many pieces, which arc
then put together in the proper shape.
This Is n costly and n long process.
many months being required for the
completion OF every gun. Tho pro-
posed new Gatling gun, cast OF solid
steel around n central core, and al
lowed TO cool by the new process Mt
the same gradual rate In oil parts Of
the entire piece, can be finished, IL Is
claimed, In about two months and at n
much less cost OF money and
labor than that required for the
Krupp or any other gun now made.
The advantage Of casting the cannon
in one piece. instead OF building IL
from several pieces, Is apparently n
great one, which can be understood
by anybody having the slightest idea
OF the work of casting ordnance.
Preparations are now being made TO
cast two six-inch guns by the new
process and test them thoroughly, and
DR. Gatling IL confident that their
superiority will be established at once.
When the guns are ready representa-
tivcs OF foreign Governments as well
IA our own will be invited 20 witness
the tests, and it IS hoped they will bo
so successful as 20 demonstrate tho
thorough superiority Of the new Cat
ling system over any other In tho
world and will result in the transfer
OF the gun-making industry from
Europe 20 America.
DR.. Gatling's invention also covers
the use OF certain other metals in COM
bination with the steel, which, it Is
claimed. will impart more homo
gcncity and strength 20 the steel.
The compound will have IA power OF
resistance greater than that Of any
metal thus far known or used In tho
manufacture OF guns. A company has
already been formed with the object
OF establishing manufactory for the
new Calling N y Times.
