Improvements in the Manufacture of Matches.
I, WILLIAM HOPKIN AKESTER, of St. Olaf's Road, Fulham, Middlesex, Elec-
trician, do hereby declare the nature of this invention to be as follows:-
This invention relates to the manufacture of matches, and has special refer-
ence to the preparation of the explosive ingredients used in such manufacture
in such a manner as to modify or eliminate their spontaneous exposive qualities
so as to enable such constituents to be manipulated or worked with less danger
to the apparatus or operatives employed in the manufacture, and to prevent
their decomposition or oxidation and liability of spontaneous combustion or
explosion after manufacture and when stored for use.
To this end, the invention is characterized by the preparation of red or amor.
phous phosphorus and of potassium chlorate for use in such manufacture, by
grinding such ingredients, separately, under benzol in which is dissolved a
quantity of paraffin wax or other suitable solid hydrocarbon soluble in benzol,
with the object of intimately admixing the particles of such explosive consti-
tuents and of coating the same with a film of wax or the like material which
will attain the desired object.
I may use suitable proportions of such explosive materials so prepared in any
suitable combination with other materials ordinarily employed in the manu-
facture of match compositions.

Improvements in the Manufacture of Matches.
I, WILLIAM HOPKIN AKESTER, formerly of St. Olaf's Road, but now of 7, Alles-
tree Road, Fulham, Middlesex, Electrician, do hereby declare the nature of this
invention and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement:-
--
This invention relates to an improvement in the manufacture of strike-any-
chlorate
and
where matches, and has for its object so to prepare red phosphorus or
of potash as to avoid the risks at present incidental to their use in admixture
in such manufacture and also the dangers incidental to the packing and trans-
port of matches tipped therewith, and thus to render the use of such phosphorus

page_text: in such manufacture (which is much to be desired on account of such use con-
ferring complete immunity from phosphorus necrosis) commercially practicable.
To this end, the invention is characterized by the preparation of such ingre-
dients, namely, the red phosphorus and chlorate of potash, or either of them,
for use in such manufacture, by grinding such ingredients, separately, or either
of them, per se, and before mixing the same with each other or with any binding
material used in such manufacture, under benzol in which is dissolved a sufficient
quantity of paraffin wax or other suitable solid hydrocarbon soluble in benzol
to saturate the benzol therewith, with the object of intimately admixing the
particles of such respective ingredients or either of them with and coating the
same with a film of wax or the like, which will enable such ingredients to be
safely used in association in the subsequent manufacture of a strike-anywhere
match composition.
After such grinding treatment, the whole is left for a sufficient time to enable
the treated particles of the red phosphorus or chlorate of potash to settle, after which
the supernatant liquor is decanted, after which the benzol is evaporated from
the remaining phosphorus or chlorate of potash leaving the same in a powdery
condition with the particles thereof coated with wax as desired.
Such ingredients so prepared may be used in association in such manufacture
in any suitable proportions, in combination with any binding materials ordinarily
employed in or suitable to such manufacture, or, either of such ingredients so
prepared may be used in association with the other thereof not so prepared in
any suitable proportions and in combination with any such ordinary or suitable
binding materials in such manufacture.
Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed, I declare that what
I claim is:
The preparation of red phosphorus and
ΟΙ
chlorate of potash for use in the
manufacture of strike-anywhere matches consisting in grinding each or either
such substance under benzol saturated with paraffin wax or other solid hydro-
carbon soluble in benzol, and evaporating the benzol taken up by the mass of
the treated substance so as to leave the particles of the latter coated with the
wax or the like, as set forth, and the employment in the manufacture of strike-
anywhere matches of red phosphorus and
chlorate of potash so treated.
