croft Street, Cleethorpes, in the County of Lincoln, do hereby declare the nature
of this invention to be as follows:
A broad cast iron shoe to be used upon the otter trawl boards for deep sea
fishing, the advantage over the shoes now in use being that it is much broader
therefore it will assist in keeping the boards in an upright position which is very
necessary it is also reversable so that when one side is worn down it can be
reversed and will be as new, the shoes now in use are very narrow and frequently
allows the boards to fall on the back which is a great disadvantage.
The shoe is sledge shaped 3 ft. 5 in. long, 6 in. high (in. broad and is fixed
en the bottom of the board and travels on the bottom of the sea.

Improvements in the Construction of Cast Iron Shoes for the Otter
Trawl Boards for Deep Sea Fishing.
We, TOM GREEN, Joiner, 71, Fildes Street, Grimsby, WILLIAM BROADBENT,
Jeiner, 62, Granville Street, Weelsby, and JoHN MARKHAM YOUNG, Ships Hus-
band, 15, Bancroft Street, Cleethorpes, all in the County of Lincolnshire, 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:
Our invention relates to what are commonly known as otter trawl boards for
deep sea fishing, and has for its object the providing of the bottom of each board
with a broad cast iron shoe for the purpose of keeping the boards in an upright
position when in the water, this being necessary, as if the boards fall over on
their backs or faces as the ordinary construction of boards frequently do, the
mouth of the net is closed, thus preventing the catching of fish, and in addition,

cannot be disentangled, this in many cases necessitating the cutting of the warps
to free the boards.
DESCRIPTION OF DRAWINGS.
Fig. is a view of the front side of an otter board, with our improved shoe
applied.
Fig. 2 is an end view of Fig. 1.
Fig. 3 is a sectional view on the dotted line 1, 2 of Fig. 1.
Fig. 4 is a side view of half of our improved shoe when in two pieces.
Fig. 5 is a transverse sectional view of shoe looking towards rounded end.
Figs. 4 and 5 are drawn to a larger scale than Figs. 1, 2 and 3.
For the purpose of our invention, we construct our improved shoe A for otter
trawl boards with an enlarged bottom or sole B preferably taper shaped from
the bottom of the shoe to the top in outside configuration, that is wider at the
bottom than at the top, a channel C runs the whole length of the shoe inside to
take the board D such channel C being preferably narrower at the bottom than
at the top, the board being bevelled off or reduced at the bottom to fit within the
channel which by being reduced, more firmly grips such board. The shoe may
have its ends rounded in an upward direction, as shown at E, in which case the
ends of the board would also be rounded to fit therein.
The shoe is provided with holes F to take bolts G, which pass through both the
shoe and the board, thus firmly binding them together, and the shoe may be in one
piece running the whole length of the board, or it may be in two or more pieces
as desired, in the latter case a plate or plates H may be employed at the part
where the two or more pieces meet, passing down between the board and the shoe
and bolted through for giving greater strength and security, also slots or holes J
may be made in the board, and bolts K having enlarged tapered heads may be
passed up through taper holes in the sole of the shoe, and through the holes
aforesaid, where a nut is screwed on the end of the bolt nipping it up tight so that
if the shoe wears away by moving on the sea bottom these bolts still keep it in
position until the taper head is worn away, which would not be until the shoe
was worn out.
Our improved shoes are reversible, thus allowing of them being turned to
opposite ends of the boards as they become worn on one side or the other, thereby
forming a new wearing surface, they may also be made any suitable size to fit
the various constructions of boards, and may be of cast iron, cast steel or other
suitable metal or material, and if desired may be an even thickness throughout
instead of taper as shown.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed we declare that what we
claim is: :-
1. A shoe A, for the bottom of otter trawl boards, consisting of one or more
pieces of metal, with a broad bottom or sole B, and having a taper or straight
channel C therein, to take the board, holes F to take the bolts, and with or
without upturned ends E, strengthening plates H, and taper bolts K, in the
manner and for the purposes substantially as shown and described.
