COMPLETE SPECIFICATION.
Improvements in Elastic Ropes.
1, FREDERICK AYCK BOURN 240 Vauxhall Bridge Road, Pimlico, Gentleman,
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:-
The object of this invention is to provide an elastic rope or cord for the purpose
of taking off the sudden pull or strain on the ropes or chains which occurs in
towing ships or drawing loads, and which so frequently snaps the said cord, rope or
cable when such are subjected to sudden strains.
I take any required length of rope or cord one end of which I fasten to a post
then I separate the strands at the other end to any required extent at the extremity
of which I place inside and between the separated strands a length of solid or
tubular vulcanized indiarubber or some such elastic material and secure the rope
and elastic material firmly together by a lashing. I then stretch the rubber to its
full extent and fasten the stretched end of it to a post or ring then 1 plait or braid
the loose strands over the rubber closely but loosely until the rubber is covered.
I then fasten them together by a lashing and release the temporary lashing then I
plait or braid the remaining strands of the rope or cord closely to the end.
Referring to the annexed drawings
Fig. 1 shows a side elevation of a rope treated according to my invention.
Fig. 2 shews a cross section through line x. y.
a is the rope to the inside of which is secured a piece of indiarubber or other
suitable material by means of a cord or lashing c or other equally convenient
means. The strands of the rope a are so arranged & laced as to permit of the
elongation of the indiarubber when the rope is subjected to strains.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
(1) The improved elastic rope consisting of a piece of indiarubber or such

page_text: suitable material secured at its ends within the strands of a piece of rope
substantially as described & for the purpose set forth.
