Improvements in Trawl Heads.
We GEORGE HAVERCROFT HUTESON and JOSEPH HUTESON of Fish Dock
Road Grimsby, Shipsmiths, do hereby declare the nature of this invention to be
as follows:-
This invention has reference to an improved trawl head whereby the breaking
or twisting of the same out of shape by the great strain on them when in use is
prevented. And consists in fixing to the innerside of the trawl head and near the
turrett which carries the bridle or towing rope (preferably within a radius of
20 inches) a connection of any suitable shape and to this we attach what we term
a fairleader, made of chain, rope, wire or any other material, and this passes
through a ring or eyelet upon the other side of the trawl head, a link, fitted to
the loose end of the fairleader, holds the ground ropes. By this arrangement the
strain of the ground ropes comes nearly in a direct line with the bridles and thus
prevents the stretching, twisting or breaking of the trawl heads.

COMPLETE SPECIFICATION.
Improvements in Trawl Heads.
We GEORGE HAVERCROFT HUTESON, and JOSEPH HUTESON, of Fish Dock
Road, Great Grimsby, in the County of Lincoln Shipsmiths 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 has reference to an improved trawl head, whereby the stretching
or twisting of the same out of shape, by the great strain upon them when in
use is prevented or materially reduced.
The duties of trawl heads are threefold.
First as carriers of the trawl beam, and the top part of the trawl-net.
Secondly as a means of connection between the bridle or towing ropes, and the
ground rope, which has the bottom part of the trawl-net afixed thereto.
Thirdly as a sinker for the trawl beam and-net to the bottom of the sea.
First and second of such duties are performed in an unsatisfactory manner
oweing to the way the strain between the bridle ropes and the ground rope is put
upon them. The bridle ropes, or wire are generally about three times the length
of the trawl beam, whereas the ground rope averages from one and a half to
twice the length of the trawl beam, "so that as an illustration the principal
strain bearing parts closely resemble an ordinary shaped boy's kite towing tail
first the trawl heads are made fast, one on each end of the trawl beam, and
oweing to the shortness of the ground rope, which it is not adviseable to lengthen,
on account of the extra expense of net," it causes the trawl heads to pull side-
ways by the toe and twist out of shape, and consequently very often breaks them
in the staple and top part of the frame.

general use. A. is a turrett to shackle bridle, or towing ropes, or wire on to.

which the trawl beam end is made fast, and the same letters refer to similar
parts in

page_text: Fig. 2. in which are illustrated the improvements, for which we are asking
Her Majesty's Royal Letters Patent. By fixing a stud or eye in the place of an
ordinary back plate revit, on the inside of the trawl head frame, marked D. near
to turrett A. this we describe as partly old insomuch as we have made and used
the same in a different form, but no other person or persons have either made or
repaired the same to the best of our knowledge and belief" in the manner shown.
And by fixing an eyelet or fairleader shown by Fig. 3. "to be described as
new to the inside of the sole by a shouldered revit marked E. Fig. 2. the revit
hole in the sole to be countersunk on the underside, to allow for the revit remaining
fast, after the sole is partly worn, the largest or top part of the revit to leave
sufficient room to allow the fairleader to move, so that it can be used on either
side of the frame of the trawl head, to suit whichever end of the trawl beam it is
made fast on.

By passing the toe chain, which is made fast on the ends of the ground rope,
through the cyclet or fairleader Fig. 3. connected with revit E. Fig. 2. and shackle
to stud D. Fig. 2. we make the principal of giveing the strain a lead at such
an angle as will prevent the pulling of the frame of the trawl head to the strain,
thereby either preventing them from stretching and twisting or materially
reduceing the same.
F Fig. 2. is an eye to lash the leech line or side of the trawl-net to.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that we
claim is :
1. A great reduction of labour in construction and especially in repairing same
retaining all the old points of utility and in addition possesing the special
advantages shown herein,
2. We ask the privilege of useing the connection D in the possition shown on
the drawings, or in the revit hole below turrett A, or preferabley in both if
required in combination with which
3. We claim fairleader Fig. 3, with shouldered revit E. Fig. 2. in the manner
shown on the drawings, or any colourable inimitation thereof, in giveing the strain
of the ground rope a lead at such an angle from the toe of the trawl heads as
shown, or on any other style or shape of trawl head" be it made with either,
rope, wire, chain or any other material whatever.
