Improvements in the Manufacture of Dynamite.
I, CARL OLOF LUNDHOLM, of the Ardeer Factory, in the County of Ayr, North
Britain, Chemist to Nobel's Explosive's Company, Limited, do hereby declare the
nature of this Invention to be as follows, that is to say :-
My said Invention has for its object by an improvement in the preparation of the
absorbent material employed in the manufacture of dynamite, to render the dynamite
not liable to injury or deterioration by water or moisture, but even capable of acting
effectively whilst immersed in or saturated with water.
The absorbent material ordinarily used in making dynamite, and known as
kieselguhr, or infusorial earth, consists principally of silica; and in the several
varieties of silicious earths including those known as diatomite, desinid earth, white
peat, and others, there is associated with the silica more or less organic or carbo-
naceous matter. For the purposes of my Invention I take a natural silicious earth
having a notable proportion of organic or carbonaceous matter, and I carbonise such
earth by heating it in retorts or other suitable vessels without access of air. The
carbonised natural earth so obtained I employ instead of ordinary kieselguhr or
uncarbonised silicious earth as an absorbent for the nitroglycerine in making
dynamite.
The extremely intimate combination of silica and carbon obtained as described has
the property of retaining the nitroglycerine in a manner to strongly resist its
separation or deterioration by water.
Dated this Twenty-eighth day of September 1888.

Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed, 1 declare that I
am aware of the Specification of Grune's Patent No. 16116 of 1887 and I lay no
claim to anything described and claimed therein, but what I claim is
-
The improvement in the manufacture of dynamite consisting in employing as the
absorbent of the nitroglycerine the substance obtained by carbonising a silicious
earth naturally containing organic or carbonaceous matter, substantially as and for
the purposes hereinbefore described.
