Smack Owner do hereby declare the nature of said Invention for "IMPROVEMENTS
IN TRAWL GEAR" to be as follows:-
:-
According to my Invention I mount each trawl head upon a number or series of
wheels or rollers (preferably three) the series being granulated in diameter and
mounted in the bottom of the trawl beads by which means trawling is considerably
eased and facilitated less labour is required for moving the apparatus about and a
great saving is effected in trawl warps and beams.

page_text: I, ROBERT PORTER, of 10 High Street, Lowestoft, in the County of Suffolk,
Smack Owner do hereby declare the nature of said Invention for "IMPROVEMENTS
IN TRAWL GEAR" and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement :-
According to my Invention I mount each trawl head that is to say the end
frames or supports of the trawl beam upon a number or series of wheels or rollers
mounted in the bottom of the said trawl heads end frames or supports by which
means trawling is considerably eased and facilitated less labour is required for
moving the apparatus about and a great saving is effected in trawl warps and
beams and less sail or canvas is required for trawling operations.
And in order that my said Invention may be fully understood I shall now
proceed more particularly to describe the same and for that purpose shall refer
to the several Figures on the annexed Sheet of Drawings the same letters of
reference indicating corresponding parts in all the Figures.
Figure 1 is a front elevation and Figure 2 is a side view of trawl gear constructed
according to my Invention. A is the trawl beam to the ends of which the trawl
heads or end frames or supports -B are fixed. The said heads end frames or
supports are provided with rollers or wheels C mounted upon axles supported in
the lower part of the heads frames or supports so that when the gear is in operation
the beam and heads frames or supports run upon these rollers or wheels. The
rollers or wheels may be in any suitable number but I prefer three to each head us
shewn and they may be all of the same size or may make them of graduated
size the larger ones in front and the smaller ones behind as shewn in dotted lines
in Figure 2. Or the larger ones may be behind and the smaller ones in front, as in
Figure 3.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed I declare that what
I claim is-
First. Providing the heads end frames or supports of trawl gear with wheels or
rollers substantially as and for the purposes herein before described and illustrated
by the accompanying Drawings.
Second. Providing the heads, end frames or supports of trawl gear with wheels
or rollers of graduated size substantially as and for the purpose herein before
described and illustrated in dotted lines in Figures 2 and 3 of the accompanying
Drawings.
