County of Lancaster, Patent Agent. "IMPROVEMENTS IN PREPARING JUTE YARN
EMPLOYED IN THE MANUFACTURE OF QUICK MATCHES' OR FUSE USED FOR
FIRING BLASTING CHARGES." A communication from abroad by Richard Francke,
of the Firm of Munch and Company, of Niderau, Saxony, Empire of Germany.
The objections to quick matches and fuse having gutta-percha covering is, that
such become hard and brash after a short storing and therefore unserviceable for
blasting work below water, and that they are expensive. As a remedy for the
defects I have found a new and improved method of preparing the jute-yarn
employed in manufacturing quick-matches and fuse, and which is as follows:-

The objection to quick matches and fuse having gutta percha covering is, that

blasting work below water, and that they are expensive.
As a remedy for the defects I have found a new and improved method of pre-
paring the jute yarn employed in manufacturing quick-matches and fuse, which is
as follows:-
One part of sugar of lead;
One part of dissolved alum; and
One part of glue; to which I add with water, the quantity
of water, more or less considerable, corresponding with the quality to be obtained.
After having steeped the jute yarn some days in the aforesaid solution the yarn
is dried and spun into quick matches in the ordinary way. After the spinning the
finished quick-matches are impregnated with tar or other resinous substance. The
quick-matches or fuse prepared and impregnated in the manner described may be
preserved several years without loss of their good qualities; they do not become
brash and broken, and are of a much lower price than the quick-matches or fuse
having gutta percha covering:
Such being the nature and object of this my said Invention the same will be
fully understood from the following description thereof:-
In the manufacture of quick-matches according to this Invention I prepare a
solution of the ingredients following, and in or about the following proportions :—
One part of sugar of lead;
One part of dissolved alum; and
One part of glue; to which I add with water, the quantity
of water, more or less considerable, corresponding with the quality to be obtained.
After having steeped the jute yarn some days in the aforesaid solution the yarn is
dried and spun into quick-matches in the ordinary way. After the spinning the
finished quick-matches are impregnated with tar or other resinous substance.
The quick-matches or fuse prepared and impregnated in the manner described
may be preserved several years without loss of their good qualities; they do not
become brash and broken, and are of a much lower price than the quick-matches
or fuse having gutta-percha covering.
Having thus fully described the nature and particulars of this said Invention,
together with the manner in which the same is to be or may be performed or
carried into practical effect, I would have it understood that I claim,-
The use of the solution composed of ingredients herein described in the preparing
jute yarn, to be employed in the manufacture of quick-matches or fuse, for purposes
set forth.
In witness whereof, I, the said Walter Brierley, have hereunto set my hand
and seal, this Twentieth day of March, in the year of our Lord One thousand
Witness,

Clerk to Walter Brierley,
