IMPROVEMENTS IN TRAWLING NETS
Year: 1884

page_text: STEPHEN KEMP, of 8 Holbeck Road, Kennington in the County of Surrey
Mechanic, do hereby declare the nature of my invention for IMPROVEMENTS IN
TRAWLING NETS, to be as follows:-
A permanent sweep rope or line round the net at or just below the ground rope,
having for its object, the closing of the net at will from the vessel, without the
necessity of keeping a constant strain on the line by which the operation is
performed, by passing through rings or thimbles fixed to leather canvas or other
suitable material as a ground work, and so arranged round the net as to secure the
sweep rope in its proper position one end passing through a single sheave block or
ring secured to the other end, and leading to the vessel, the sweep rope to be
provided with two metal cones, one to secure the net open and the other to secure
it shut, by being drawn through a spring lock secured to the under side of the
trawl beam, when the line by which the operation is performed may be cast over-
board and the net will come up shut, thereby securing all fish within the net at
the moment of commencing to haul up.

STEPHEN KEMP, of 8 Holbeck Road Kennington in the County of Surrey,
Mechanic do hereby declare the nature of my invention for IMPROVEMENTS
IN TRAWLING NETS and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement :-
A permanent sweep rope or line round the net, at or just below the groundrope,
having for its object the closing of the net at will from the vessel, without the
necessity of keeping a constant strain on the line by which the operation is
performed, by passing through rings or thimbles fixed to leather canvas or other
suitable material as a groundwork, and so arranged round the net as to secure
the sweeprope in its proper position, one end passing through a single sheave
block or ring secured to the other end and leading to the vessel, the sweeprope to
be provided with two metal cones, one to secure the net open and the other to
secure it shut, by being drawn through a spring lock secured to the underside of
the trawlbeam when the line by which the operation is performed may be cast
overboard and the net will come up shut thereby securing all fish within the net
before leaving the ground, the length of rope between the two cones should be
equal to the circumferance of the net, so that when the cone B1 is drawn through
the lock the net is securely shut, the line from the first cone B need not be
larger than a leadline and may be made fast to the trawl warp 8 or 10 fathoms
above the juncture of the bridles so that it reaches the vessel before the gear is
raised from the ground.
I will now by the aid of accompanying drawings proceed to describe more in
detail means pursued by me in carrying my improvements into effect-fig 1 is a
front view fig 2 is a plan view figure 3 is an end view A is a fixed cheek or
jaw A 1 is a luo e cheek working within a channel. and kept in position by a
spring or springs which springs may be spiral or otherwise and made to any
strength B and B 1 are the cones through which the sweeprope pass and may be
stopped on the rope in any desired position. C is the trawlbeam.
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
The novelty of the lock and cone arrangement substantially as and for the
purpose hereinbefore described and illustrated by the accompanying drawings.
Dated this Seventh day of April one thousand eight hundred and eighty five.
