PROVISIONAL SPECIFICATION.
Improved Angled Side Roller Trawl Ports.
ROBERT ELWOOD ELLIS, Shipbuilder, Roseville, Inverkeithing and
ALEXANDER KAY Trawl Owner, 17 Restalrig Terrace, Leith, do hereby declare
the nature of this invention to be as follows:-
The invention consists of a new design and arrangement of trawlports for use in
steam and sailing fishing vessels and the following is a descriptive outline of the
nature of same. The side rollers are fitted at an angle of about 25° off the vertical
line and are made of an extra large diameter and fitted with cap or projecting lip
on top ends. Our object in fitting the rollers at an angle instead of vertical, as
usually done, is to obviate the chance of the warp working across their faces in a
direction not square to their surface, and by angling the rollers this is overcome
with the result that in lying true to their work there is no possibility of jamming
when the warp strain bears on them and by continuing to revolve the wear and tear
of themselves and the trawl-warp is reduced to a minimum. The top portion of
the casting or chair, which is fixed to the side of the vessel, is made with a couple
of projecting horns at the top of the side angled rollers mentioned above. These
horns together with the capped rollers are formed so as to prevent the warp from
jumping or slipping in bad weather-out from the space between the rollers when
the vessel rolls, besides enabling fishing operations to be prosecuted with the warp
outside vessel through the trawlport instead of inside through a block fixed on deck
leading aft-as at present, and are to take the place of the usual portable rod or
pin across the inside of the main part of trawlport. There are also two horizontal
rollers the one of large diameter fitted inside, and one of small diameter fitted
outside. All rollers are made solid and revolve on turned iron or steel pins which
are portable and can be taken out for examination when necessary.
The benefits claimed for the invention are
1st. Reduced cost and extra strength.
2nd. Saving in upkeep of rollers & warp.
Minimum risk of accidents to crew

We, ROBERT ELWOOD ELLIS, Shipbuilder, and ALEXANDER KAY, Trawl
Owner, both of 17 Restalrig Terrace, Leith, in the County of Midlothian, North
Britain, 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 relates to improvements in angled side roller trawl ports for use in
steam and sailing fishing vessels, and has for its object to so arrange the side rollers
at an angle, in lieu of vertical as hitherto, as to obviate the chance of the warp

page_text: working across their faces in a direction not square to their surfaces; and by
angling the said rollers this is overcome with the result that in lying true to their
work and having larger diameter there is no possibility of jamming when the warp
strain bears on them and revolving being ensured the wear and tear of themselves
and the trawl warp is reduced to a minimum.
In describing our invention we will refer to the accompanying drawings.
Figure 1 is a back view, Figure 2.a front view and Figure 3. a plan of our
improved trawl port, and
Figure 4 is a detail.
Referring to the said drawings, we employ a casting or chair A which is fixed,
by suitable means, to the side of the vessel and formed or provided with the
necessary means for carrying both the angled and horizontal rollers B, B' and C, C¹.
The side rollers B, B' are fitted.in the said chair A at an angle of about 25 degrees
off the vertical line, and they are formed or provided at their top ends with caps or
projecting lips, and the top part of the chair A is formed with a couple of pro-
jecting horns G, which along with caps b of the rollers B, B¹ prevent the warp from
jumping or slipping in bad weather out from the space D between the said rollers
when the vessel rolls, besides, enabling fishing operations to be prosecuted with the
warp outside the vessel through the trawl ports, in lieu of inside the vessel through
a block fixed on the deck leading aft as hitherto; said rollers B, B¹ and horus G
thus take the place of and dispense with the ordinary portable red or pin across the
inside of the main part of the trawl port. The said chair A has mounted on its
inside a horizontal roller C and another one C₁ of smaller diameter on its outside so
as to the more effectually guide and facilitate..the working of, the warp and also
-save the chafing of the vessels.side.
All of the foregoing rollers are made solid and are mounted; loosely on turned
iron or steel pins E which are mounted, in such a manner, as to enable them to be
taken out for inspection and repairs when necessary.
The whole arrangement thus forms an efficient trawl. port.
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 what we,
claim is
1st. The general arrangement, construction and combination of the various parts
constituting our improved trawl port, substantially as hereinbefore described and
shown in the accompanying drawings.
2nd. In trawl ports for fishing vessels, mounting the side rollers at an angle of.
about 25 degrees from the vertical line, substantially as and for the purposes
hereinbefore described and shown in the accompanying drawings.
3rd. In trawl ports for fishing vessels having angled side rollers, forming or
providing the said rollers with caps or projecting lips, and also forming or providing
the chair with projecting horns G, substantially as and for the purposes hereinbefore.
described and shown in the accompanying drawings.
