Improvements or commette WICK 332
I, EDWARD LYON BERTHON, of The Vicarage, Romsey, Hants, Master of Arts,
do hereby declare the nature of this invention to be as follows:-
This invention relates to certain improvements in or connected with sea anchors,
or what are known as drogues.
The invention consists in making the frames of such anchors or drogues in two
parts jointed together at their ends, so that they can be folded close together, or be
opened out when required.
The two half frames have canvas attached and a portion of said canvas forms a kind
of bag which holds the water when the drogue is thrown overboard to immerse it to
the desired depth and act as a drag. The canvas bag is of tapered shape and near
the end I arrange a cord, or it may be a chain, so that when the drogue has to be
emptied of water previous to being hauled inboard, that end is easily lifted by a
boat hook for that purpose.
Any number of lines can be run from the two side frames to a ring to which the
drag line can be affixed.

COMPLETE SPECIFICATION.
Improvements in or connected with Sea Anchors.
1 EDWARD LYON BERTHON of The Vicarage, Romsey, Hants, Master of Arts, do
hereby declare the nature of my said 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 certain improvements in or connected with sea anchors
or what are known as drogues.
The invention will be clearly understood by the annexed drawings.
Figure 1 is a plan elevation with the frame opened out and looking into the bag.
Figure 2 is a side elevation, and Figure 3 a folded up frame, the bag being within it.
The invention consists in making the frames of such anchors or drogues in two
parts A, B, jointed together at their ends C, C, so that they can be folded close
together and retain the bag within them or be opened out when required for filling
with water when thrown overboard.
The two half frames A, B, have canvas D attached and a portion of said canvas
forms a kind of oval conical bag which holds the water when the drogue is thrown
overboard to immerse it to the desired depth and act as a drag. The canvas bag D is
of tapered shape and near the end I arrange holes E, E, or a cord or it may be a
chain so that when the drogue bas to be emptied of water previous to being hauled
inboard that end is easily lifted by a boat hook for that purpose.
Any number of lines F can be run from the two frames A, B, to a ring or bight G
to which the drag line or warp can be affixed.
'
I have in the drawings shown the drogue or sea anchor with elliptical shaped
frame A, B, but it may be of any other shape and if holes be made at or near the
apex or the bottom of the bag the oozing out of the water through those holes will
materially assist the action of the drogue, and facilitate the water leaving the bag
when being hauled in.

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. Making the frame of a drogue or sea anchor to fold, substantially as shown on
the annexed drawings.
2. Hinging part frames of a sea anchor or drogue for folding towards and against
each other as and for the purpose described.
