EXPLOSIVE COMPOUND.1,054,515.
I. Drawing.Specifiation of
Application ffled May 27To all wAom it may concern:
Be it known that I, CHARLES F. DIPPEL,
a citizen of the United States, residing at'
Brenham, in the county of Washington and
5 State of Texas, have invented certain new
and useful Improvements in Explosive
Compounds, of which the following is a
specification.
This 'invention relates to explosive com-
10 pounds of that character employing as a
base potassium chlorate or its equivalent,
the object of the invention being to provide
an explosive compound of this particular
type which is free from the defects of prior
15 explosives of its class' and which embodies
substantial advantages resulting from its
particular combination of ingredients and
their 'specific coaction, as hereinafter fully
described.
20. In carrying my invention into practice I
provide an explosive compound consisting,
essentially, of potassium chlorate, two parts,
white granulated sugar, one part, and alco-
hol sufficient to slightly moisten the mass,
25 although more or less alcohol may be used
according to the rapidity of ignition desired
or period for which the compound is to be
kept before use. In practice, denatured
alcohol (such as grain alcohol containing
30 a denaturing substance consisting of or in-
cluding petroleum benzin or other volatile
hydrocarbon) is preferably employed.
The compound is prepared in suitable
quantities by simply mixing the ingredients
35 in the proportions named. This can be
done by putting the potassium chlorate and
granulated sugar in a tube or receptacle,
sprinkling the alcohol thereon, and then
stirring and mixing the mass by means of a
40 wooden paddle. The compound is then
sealed for use or sale in air-tight receptacles,
thereby evaporation of the alcohol is elimi-
nated or reduced to the minimum.
The compound thus manufactured is
45 ready for immediate use, but does not
deteriorate or become dangerous with age,
and hence possesses desirable keeping quali-
ties. Experiments have shown that quanti-
ties of this compound manufactured sixteen
50 months ignite as rapidly and explode with
the same force a, quantities.recently made.
It has also been demonstrated that the com-'
pound may be safely mixed and handled, as
it does not explode by attrition or concus-
55 sion, in which respect it differs from allletters Patent. Patented Feb. 25,1913.
1912. Serial No. 699,872.
prior chlorate of potash explosives with
which I am. familiar, and does not require
the dangerous use of caps to explode it, as
it may be set off by means of a fuse as in the
use of ordinary explosive powders. How- eo
ever, it may be exploded by the use of caps,
if desired.. Unless this compound is con-
fined, it will not explode upo ignition, but
will simply burn up.
The explosive can be made into sticks of 65
suitable size, which can be used for blast-
ing under water or for overhead blasting.
These sticks are made by pressing the com-
pound into molds, of such size as desired,
immediately after mixing. After being 70:
thus pressed into molds and dried therein,
the sticks are hard and when subjected to a
spark will explode with the same degree of
force as the powder. For use under water,
the sticks must be wrapped in oil paper, or 75'
coated with paraffin. These sticks, unlike
dynamite, do not become dangerous with
age, are not dangerous in handling, and do
not explode by concussion, and are there-
fore a more uiseful exposive than dynamite.. 80
The coating of these sticks with paraffin
will serve to prevent evaporation of the
alcohol. Sodium chlorate may under some
conditions be used with advantage instead
of and as a substitute for potassium chlo- 8'5
rate, and such- modification is held to fall
within the scope of the invention.
This improved explosive compound has
considerably greater strength than gun-
powder or blasting powder, and approxi- 90
mately the same explosive force as forty per
cent. dynamite, but has greater blasting
power than dynamite of this strength, as,
unlike dynamite, it gives a high degree of
breaking power in all directions. It is 95
highly desirable for use in blasting in mines,
tunnels, quarries and other inclosed spaces,
as it does not generate any inconvenient or
annoying amount of noxious gases and in-
volve the loss of time and expenses incurred 100
in ridding a mine'of gases after a blasting
operation. Moreover, the explosive is
cheap, and by its use a greater amount of
material. may be blasted out with a given
amount of explosive than by the use of any 105
of the ordinary blasting powders. The
compound may also be used as a smokeless
powder for firearms, as it will not foul or
otherwise injure the gun.
It is well known that many attempts have 110
