do hereby declare the nature of my invention for AN IMPROVEMENT IN THE MANU
FACTURE OF THE GIMP USED BY ANGLERS to be as follows:-
4
With the object of strengthening and rendering more lasting the gimp now used
by anglers, I add to the floss silk interior of the gimp two or more strands-
(according to the thickness of the gimp) of very fine ductile wire. The wire would
be added also to those inferior gimps where the interior is not of pure floss silk,.
but mixed with cotton or some such material.

3 do hereby declare the nature of my invention for AN IMPROVEMENT IN THE MANU-
FACTURE OF THE GIMP USED BY ANGLERS and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:
The ordinary gimp used by anglers is a line of twisted floss silk or some other
similar material served round with fine brass, copper or other metal wire.

page_text: In my Invention one or more strands of fine wire are added to the floss silk,
thereby rendering the gimp not only stronger but at the same time more durable.
Any strong wire answers for the purpose but one of the best metals is a patent
composition called "phosphor-bronze," which has great tensile strength, is fairly
ductile and does not rust. In the very small sizes of gimp such as that known as
No. 000, it is desirable to use only one strand of phosphor-bronze wire which is laid
in the centre of the floss-silk before the twisting commences. The manufacture
then goes on after the ordinary method: the size of the wire used must depend on
the amount of strength required. In the larger sized gimps, a single wire can also
be used, and this gives great strength and is specially suitable for use in sea-fishing,
but it renders the gimp very stiff. For kinds of angling where more pliant gimp
is required it is better to use a number of very fine wires which are mixed with
the silk before it is twisted, the ordinary process of gimp manufacture being after-
wards followed. Where it is desirable to manufacture this gimp at as low a cost as
possible the silk can be mixed with cotton or some other similar cheap substance,
or entirely replaced by it, for the strength of the gimp lies mostly in the interior
wire. The guage of the single strand of wire in the 000 gimp and the number of
strands of wire in the larger sizes should be varied according to the amount of
strength and pliancy required-the thicker the wire the greater the strength and
the less the pliancy. An advantage claimed for this invention besides those
already mentioned is that jack, mahseer, and other fish having mouths armed
with teeth, are less likely to bite through it than through ordinary gimp.
I do not claim novelty for my invention for any other gimp than the gimp used
by anglers.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is
An improvement in the gimp used by anglers, by the admixtufe of one or more
strands of fine wire with the silk or other substance of which the interior of the
gimp is composed.
