PROVISIONAL SPECT
ION
Improvements in Trawl-warp Fairleaders for Steam and other
Fishing Vessels.
I CHARLES FREDERICK AMOS, trading as Amos & Smith, Engineers, Albert
Dock Works, Hull, do hereby declare the nature of this invention to be as
follows:-
This invention relates to apparatus for hauling in nets of steam and other fishing
vessels.
In fitting up trawlers, it has been found requisite to fix a fairleader on the ship,
for the purpose of guiding the trawl ropes to the steam winch or capstan. Such
fairleader has hitherto been constructed with a roller running loose upon a fixed
pin set in a frame, but this construction has entailed great wear and tear on the
pin and anti-friction roller.
To remove this inconvenience, I securely fasten the pin into the roller, either by
keying it in, or so securing it that the two turn together. The ends of the pin
projecting from the roller, form journals which run in hearings, preferably lined
with brass. To these bearings I fit adjustable caps, by means of which, the wear
of the journals can be taken up in the usual way known to practical engineers, and
all unnecessary wear and tear will be thereby avoided.
Dated this 7th day of February 1896.

COMPLETE SPECIFICATION.
Improvements in Trawl-warp Fairleaders for Steam and other
Fishing Vessels.
I CHARLES FREDERICK AMOS, trading as Amos & Smith, Engineers, Albert
Dock Works, Hull, 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 apparatus for bauling in nets of steam and other fishing
vessels.
In fitting up trawlers, it has been found requisite to fix a fairleader on the ship,
for the purpose of guiding the trawl ropes to the steam winch or capstan. Such
fairleader has hitherto been constructed with a roller running loose upon a fixed
pin set in a frame, but this construction has entailed great wear and tear on the
pin and anti-friction roller.
To remove this inconvenience, I convert the pin into a spindle, and fix the rollers
thereto. The ends of the spindle projecting from the roller form journals which
run in bearings in the frame, which bearings are preferably lined with brass. To

page_text: these bearings I fit adjustable caps by means of which the wear of the journals can
be taken up in the usual way known to practical engineers.
To give access to the lower cap which is contained in the lubricant reservoir,
I provide a detachable piece, which, when bolted to the frame, forins, with the
frame, the lubricant chamber for the lower bearing.
In the accompanying drawing,
Fig. 1 is a vertical section, and
Fig. 2 is a plan or top view of my improved trawl warp fairleader.
A is the frame, made of cast iron, and provided with two bearings for the
reception of the vertical spindle B. Made fast to this spindle, so that it may
rotate therewith, is the antifriction roller C. The lower end of the spindle B is
rounded, and rests upon a steel or other plate fitted to the bottom of the
frame A. The frame is cast with a broad flange forming a base to receive holding-
down bolts.
D D are the adjustable caps for their respective bearings, and E is a detachable
flanged piece made fast by stud screws and nuts to the frame, and constituting with
it the lubricating chamber F. The cap D, it will be seen, is always accessible for
adjustment, to compensate for the wear of the brasses, but in order to gain access
to the cap D', for the like purpose, the detachable flanged piece E must be removed
by first withdrawing the securing nuts from their stud pins.
To prevent undue friction between the roller and the top bearing which serves
to keep the roller and spindle from rising in the frame, the upper cap piece is
provided with a small cup d, from which a diagonal passage leads to the bottom of
the bearing, for the purpose of conducting the lubricant to the top of the roller.
The spindle is covered at the top by a cap b to prevent access of dirt thereto.
From the foregoing description, it will be understood that the wear and tear of
trawl-warp fairleaders, as hitherto constructed, is considerably lessened by my
improved mode of mounting the roller, and providing for the adjustment of the
spindle.
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 :-
The construction of trawl-warp fairleader as above described with reference to
the drawing, whereby the wear and tear of the roller and spindle is materially
diminished.
