IMPROVEMENTS IN THE MANUFACTURE OF WATERLAID ROPES OR WARPS FOR TRAWLING
Year: 1885

page_text: I HENRY WARDale Hall of Barton-upon-Humber in the County of Lincoln
and of No 5 East End, Saint Andrews Dock in the Borough and County of
Kingston-upon-Hull Rope Maker, do hereby declare the nature of my invention
for IMPROVEMENTS IN THE MANUFACTURE OF WATERLAID ROPES OR WARPS FOR
TRAWLING to be as follows
"
-
The object of this Invention is to increase the strength of waterlud ropes or
warps for triwling This I effect either by making such ropes or warps without
any cential heart or by making the central heart el istic if heart is employed
When I close or lay up the warps without any central heart I make each of the
strands out of which the warp is made out of four lisoms instead of three (that is
out of 4 small strands instead of 3 small strands) and I lay up the warp out of 3
such stands instead of out of 4 as in the ordinary method now in use
A warp made in this way is stronger and less liable to flatten on the gunwale of
the vessel when in use and at the same time has equal biting surface on the lags
of the capstan and dummy as the ordinary 12 or 14 lisom warp now in use and
the lisoms are less liable to chafe because each knuckle will be longer
Small hearts may be put in the strands of this warp or not as may be most
advantageous
When I make the rope or warp with a central heart in place of making the
heart of manilla I make it of coir yarn, in order that when the warp is in use and
under great strain the heart may stretch with the rope instead of breaking as
they often do when made of the same fibre as the warp is made In this way by
keeping an entire unbroken heart in the rope the strength of the rope is increased
by the amount of the strength of the heart and in addition when the warp is old
and is unlaid to make running gear and ground-ropes, the heart (which is useless
as the warps are now made it being broken up into short lengths) will under my
improved method remain whole and be useful for a variety of purposes

I HENRY WARDALE HALL of Barton-upon-Humber in the County of Lincoln
and of N° 5 East End Saint Andrews Dock in the Borough and County of
Kingston-upon-Hull, Rope Maker 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 increase the strength of waterlaid ropes or
warps for trawling
This I effect by making each of the strands out of which the warp is made out
of four lisoms instead of three (that is out of 4 small strands instead of 3 small
slands) and I lay up the warp out of 3 such strands instead of out of 4 as in the
ordinary method now in use
Each lisom I form in the ordinary way by preference from Manilla fibre each
strand also I form in the ordinary way from the lisoms except that as above
stated I form them from four lisoms instead of from three Preferably I put a
small heart of Coir or Manilla (preferably Coir) in each strand but the strands
might be made without a central heart if desired
A warp made up as heretofore is shown at Figure 1 and my new warp is shewn
at Figure 2
In Figure 2 A A are the ends of four lisoms forming one of the three strands B
of the new rope. C is a small central heart of this strand
In Figure 1 B B are the four strands of the rope made up as heretofore and D
a central heart around which the strands B are laid
A warp made in my new way is stronger and less liable to flatten on the gun-
wale of the vessel when in use and at the same time has equal biting surface on
the lags of the capstan and dummy, as the ordinary 12 or 16 lisom warp now in
use and the lisoms are less liable to chafe because each knuckle of the lisoms will
be longer
A central heart of elastic coir yarn or other yarn may be put into the three
strand warp if desired-I prefer however to make it without any central heart
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 18
The manufacture of waterland ropes or warps for trawling with three strands each
composed of four lisoms substantially as described either with or without a small
central heart in each strand as desired
