"Improvements in or connected with Trawling Apparatus for Steam
Trawlers or the like."
I THOMAS SUDRON, of 9 Castle Street, Hull, in the County of Yorkshire,
Engineer, do hereby declare the nature of this Invention to be as follows:
The object of my invention, is to provide an improved apparatus for raising and
lowering the otter or trawl boards of fishing vessels from the deck, over the side,
and into the sea, or from the sea, over the side, and on to the deck of such vessel,
as required, for the purpose of dispensing with the unseemly gallows at present in
use, and allowing of them being put out into the sea, or drawn out of the sea and
hauled up on to the deck, without the difficulty and danger to life and limb, which
such operation has hitherto engendered, at the same time, my apparatus acts as
a fairlead for the trawl warp or rope, thus preventing wear and tear.
For the purpose of my invention, I employ a vertical tube or hollow pedestal,
of any suitable height, this tube or the like, is fitted to the deck of the vessel, and
is provided at its bottom end with a roller, preferably mounted in jaws formed
at or near the bottom end of such tube, at any suitable height the said tube is
reduced to form a projection, also hollow, to take a sleeve, which turns around
such reduced part, the bottom of the sleeve preferably bearing on a flange formed
on the aforesaid tube at or near the reduced part.
If desired, balls, rollers, or other antifriction runners, may be placed between
the bottom of the sleeve, and the flange on the tube, to allow of such sleeve turn-
ing freely, and to prevent clogging.
The aforesaid sleeve is provided with jaws to take a roller, over which the trawl
warp passes, such
the said roller moarp is connected to the aforesaid otter boards, and runs over
on the sleeve, down through such sleeve, and through the
tube or pedestal, over the roller mounted at the bottom of such pedestal, to
the winch, to which it may be guided by any suitable number of bollards on the
deck of the vessel.
The boards are hauled on to the deck or dropped into the sea, by this means,
the sleeve working on the reduced part of the tube or pedestal and with the roller
mounted thereon, conforming to any direction of the trawl warp or rope.

page_text: the same is to be performed, to be particularly described and ascertained in and by
the following statement:-
The object of my invention is to provide an improved apparatus, for raising and
lowering the otter or trawl boards of fishing vessels, from the deck, over the side
and into the sea, or from the sea, over the side and on to the deck of such vessel
as required, for the purpose of dispensing with the unseemly gallows at present
in use, and allowing of such otter or trawl boards being put out into the sea or
drawn out of the sea and hauled up on to the deck, without the difficulty and
danger to life and limb which such operation has hitherto engendered. At the
same time, my apparatus acts as a fairlead for the trawl warp or rope, thus prevent-
ing wear and tear.
DESCRIPTION OF DRAWINGS.
Fig 1. Shows a side elevation of our improved apparatus for raising or lower-
ing otter or trawl boards on fishing vessels.
Fig 2. Is a sectional view of Fig 1.
Fig 3. Is a plan view of sleeve, showing jaws.
Fig 4. Is a view through line 1, 2 of Fig 1.
For the purpose of my invention, I employ an appliance, consisting of a vertical
tube or hollow pedestal A, of any suitable height, this tube or the like, is prefer-
ably fitted to the deck of the vessel, by bolts or the like B, and is provided at its
bottom end with a roller C, preferably mounted in jaws D, formed at or near the
bottom end of such tube; at any suitable height, the said tube A is reduced to
form a projection A', also hollow, (or it may be continued straight instead of being
reduced, or be enlarged if found advantageous) to take a sleeve E, which turns
around such reduced or projecting part A', the bottom of the sleeve preferably
bearing on a flange A2 formed on the aforesaid tube or pedestal A, at or near the
reduced or projecting part.
The said sleeve E, may have a hole in it to take a pin, threaded bolt, or the
like F, to bind or hold the sleeve in any suitable position when it is desirable that
it should not turn, the sleeve being held firm when such bolt is nipped up tight to
bite the projection A¹; or if a plain pin is used, holes may be formed in the said
projection at suitable distances apart, the pin when passed through the hole in
the sleeve and into one of the holes in the projection answers the same purpose.
Check pieces G, may be formed or placed in the pedestal A near to the jaws D,
to fill up the space between the roller C and the rounded part of such pedestal at
that part, for the purpose of preventing the warp H from being caught between
the roller C and the inside rounded part of the pedestal A, or if desired, the jaws D
may be continued to form projections inside, for that purpose. If desired balls,
rollers, or other antifriction runners J, may be placed between the bottom of the
sleeve E, and the flange A³, on the tube, such sleeve having preferably a flange E¹
formed on it, the balls or the like.J, running in a circular race, or hollow between
the two flanges A2 and E', to allow of such sleeve turning freely and to prevent
clogging. The aforesaid sleeve E, is provided with jaws K, to take a roller L, over
which the trawl warp H passes, such warp is connected to the aforesaid otter
boards and runs over the said roller L mounted on the sleeve E, down through
such sleeve and through the tube or pedestal A, underneath the roller C mounted
at the bottom of such pedestal, to the winch, to which it may be guided by any
suitable number of bollards on the deck of the vessel.
If desired, a stay M may be employed, running from the top of the sleeve E to
any part of the vessel, for the purpose of acting as a support and giving strength
to the structure. The boards are hauled on to the deck or dropped into the sea
by this means; the sleeve working on the reduced or other part of the tube, which
forms an upwardly projecting part of the pedestal, and, with the roller mounted
thereon, conforming to any direction of the trawl warp or rope.

page_text: 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. An appliance for use on fishing vessels, consisting of a hollow tube A, pro-
vided with a roller or rollers C, and a swivelling top E, provided with a bollard
or roller L, in the manner and for the purpose substantially as shown and
described.
2. The combination of a tube or pedestal A, provided with a projecting part
such as A', roller or rollers C, and with or without flange A³, the sleeve E with
bollard or roller L, and with or without stay M and antifriction runners J, in the
manner and for the purposes substantially as set forth in the accompanying
specification and drawings.
