Improvement in Otter Trawl Nets.
SAMUEL BUCKINGHAM, Fisherman, 47, Duke Street, Gt. Grimsby, Lincolnshire,
and I, JOHN ELTON, of 59, Duke Street, New Clee, Grimsby, in the County of
Lincolnshire, Buoy Manufacturer, do hereby declare the nature of this invention
to be as follows:-
The object of our invention is to so arrange and construct otter trawl nets, so as
to lessen their liability of lifting, the foot rope of the bottom when fishing. That
part of the trawl net, called the wings, now in use, are the same as used in the
ordinary beam trawl net. They are braided with creasings on the outer salvage,
and narrowings on the inner salvage. The consequence is that the ends is.
oblique, causing the net, when made fast to the otter board, (which is square)
to drag or girt, consequently lifting the footrope of the bottom. To obviate this
inconvenience our invention preferably is to braide the wings with no creasings
on the outer salvage and narrowings on the inner salvage until they are the
required width, and then to braide a straight salvage, making the ends square.

improvement in Otter Trawi Iets,
We, that is I, SAMUEL BUCKINGHAM, of 47, Duke Street, New Clee, Grimsby, in
the County of Lincolnshire, Foreman, and I, JOHN EPTON, of 59, Duke Street,
New Clee, Grimsby, in the County of Lincolnshire, Buoy Manufacturer, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following state-
ment;
-
The object of this invention is to so construct and arrange otter trawl nets, so
as to give them a more open flow and there-by diminish the liability of lifting the
footrope from the bottom when fishing.
To further elucidate this invention we here explain that the part of the net
technically known as the wings is the peice of net fixed between the square and the
footrope, the square being the top or upper part of the net and the footrope being
a thick rope which should when fishing always be on the bottom and to which all
the lower edges or underneath parts of the net are indirectly attached:
The wings form the two sides of the front part of the net, and it is to this part
of the net to which our invention applies.

page_text: G is the wing line.
Fig. 1 shows the old type of wing with fly-meshes C and creaseings D from end to
end, when working it forms an oblique peice of net, the end of the wing being made
fast by means of the wing-line G, to the otter board F, this obliquity causes it to
pull or drag thwartwise from the bottom upwards, as shown in Fig. 3.
For the purpose of our invention we preferably set up our wings at from two to
three hundred meshes, we then preferably make our wing with flymeshes C on
the lower selvege B, and either with or without creaseings 1) on the upper selvege A
until the wing is reduced to the required width, we then despence with both
creaseings I and fly meshes C, and then make a double selvege A at the top, and
also a double selvege B at bottom, there-by making a wing of square net to the
otter board ', and placeing less strain on the wingline G, this has the effect of
doing away with the obliquity, and consequently with the thwart pull, thus
allowing the net to be always full and open, and the footrope, E, always on the
bottom.
Having now particularly described and acertained the nature of this inven-
tion and in what manner the same is to be performed, we declare that what we
claim is:-
I In otter trawls the constructing of wings when sufficiently reduced with
straight selveges, despenceing with both creascings and flymeshes, for the purposes,
shown and described.
2. The making of the end of the wing square to the otter board in the manner
and for the purposes shown and described.
3. The general arrangement and construction of wings for otter trawls for
the purposes substantially, as shown and described.
