TRAWLING GEAR.

Application led December 6, 1923. Serial No. 678,905.

To all whom, it may come/m.' l

Be it known that we, REN LoUrs MARIE DANIELOU and JACQUES JULES VERI-rouvrir, citizens of the French Republic, residing at Lorient, Morbihan, in the French Republic, have invented new and useful Imprcvem ents in Trawling Gears, of which the following Sis a specification.

This invention relates to the trawling gears used in connection with the ishing nets which are adapted to be towed by a single boat through the intermediary of two cables or hawsers connecting to the boat two boards situated during the fishing at a great distance from one another, these boards being connected on the other hand with the braces of the wings ofthe net by two cables or lines of great length which converge towards the latter.

lVith devices of this class, such as are constructed up to the present, the immers ing of the net in the water and its removal, offer certain difficulties and drawbacks which are obviated by the arrangement which is the object of the present invention.

According to the invention, for each board, the tow hawser is removably attached to one face of said board and the line leading to the brace of the net wing is removably attached to the other face of the board, these attaching points of the hawser and the line being connected by means of an intermediary cable. A

In the appended drawing, given by way of example:

Fig. 1 is an elevation of the board provided with its attaching means.

Fig. 2 is a plan view of the whole devlce in operation and when towed.V

Fig. 3 is a view of the successive cables, after the removal of the board, during the winding of said cables on the fishing winch.

-Fig. 4 shows a modification of the means for connecting the intermediary cable and the board to the line.

As is well known, the hawser 1 connected with the boat is attached at the other end to the board 2 as well as the line"3 whichthe outer face of the board is attached a crows foot 9 carrying a shackle 10.

The hawser 1 carries at its end, towards the board, a turnbuckle 11 and a link 12 which can be engaged in the shackle 7. The

line 3, leading to the net, is provided at its end with a turnbuckle 15 and a link 13 which can be engaged in the shackle 10. A connecting cable 14 extends through the opening 8 of the board and connects together the two links 12 and 13. The length of said connecting cable is greater than the distance w-y between the shackles 7 and 10, during the operation, when the net is towed.

When the trawling net is at the bottom of the water, in order to draw it, that is to -say to bring it on board, each hawser 1 is wound upon the fishing winch, and when the corresponding board is brought out of the water, it is hung upon the bracket adapted toreceive it, the winch is rotated backward so as to slacken the hawser 1, and the link 12 can easily be removed from the shackle 7 The winch is then rotated forward, in order-to wind the hawser 1 and then the cable 14, the shackle 10 thus passing through the hole 8 in the board. The crows foot 9 is thus slackened, so that one can readily remove the link 13 from the shackle 10. One can then wind the line 3 on the winch,- so as to draw in the net. The line 3 is connected, as is known, with the brace of the net wing by a crows foot, and to the` latter is often attached one or more cables proceeding to the top rope and to the ground rope of the net. The ends of the crows foot and the ends of these cables will finally pass through the opening 8 in the board when theA net is brought on deck, and one can thus readilydetach them from the line 3 so as to finally hoist the net on board.

To immerse the net and the boards into lthe water, the inverse operation is performed.

Other means may be used for connecting the intermediary cable 14 to the line 3, while affording the same advantages, i. e.

.while permitting to wind the line 3 by passeoA ticularly adapted for the case in which the cheeks of the drum of the winch will not I and constructed as shown in Figs. 1 and 2. In this case the cable 14 and the line 3 are connected by means of two couplings or splices 25 so arranged that one of the cables is slackened and allows the rapid insertion or removal of a shackle 24 removably attached to the crows Aroot 9.

'It will be seen that b means of this arrangement, one can win the lines 3 as well as the hawsers 1 on the fishing winch instead of having to mount the lines by hand, which latter operation was very difficult, especially in bad weather. The lines can also be manipulated without being obliged to provide on board any additional installations. On the other hand the lines, being no longer manipulated by hand, can have any desired makeup and are no more necessarily made of mixed rope, and all risk of wounds occasioned by steel pieces projecting out of the hemp are 'obviated Lastly, the operation is very rapid, b'oth for the drawing and for the laying; it suffices in fact, for drawing in the net, to hang up the two boards and to remove the shackles Z and 10. The o eration of laying is also easier thanA before, or the risk of engaging the lines or boards in the propeller` is thus considerably reduced, and moreover, the vessel preserves its freedom'of movement during the laying operation which is not possible when this is done by hand. c

Finally, the openin in the board has the advantage of diminis ing the resistance of the water.

It will be understood that the inter-l integral part of the tow hawser or of the line, or of both at a time, the shackles 7 being then connected in a suitable manner with the cable.

The invention is not limited, of course, to the details of construction shown and described, and these have been chosen only by way of example.

Having now described our invention what we claim as new and desire to secure by Letters Patent is 1. A towing-device for trawl nets comprising a towing line adapted to be. connected to one of the net wings, an otter -adapted to be connected to the boat, a detachable shackle for detachably connecting the tow hawser to said brackets, means for detachably connecting the towing line to the outer face of said board and an intermediate cable adapted to connect said hawser to said towing line.

3. A towing device for trawl nets comprising a towing line adapted to be connected to one of the net wings, an otter board, brackets secured on the inner face of said board, a crow foot member secured to the outer face of said board, a tow hawser ada ted to bev connected to the boat, a shackle or detachably connecting the tow hawser. to said brackets, a shackle for detachably connecting `said hawser to said towing line.

' 4. A towing device for trawl nets comprising a towing line adapted to'be connected to one of the net wings, an otter board, brackets secured on the inner face of the board, a crow foot member secured on the outer face of said board, a tow hawser adapted to be connected to the boat, means for detachably,

connecting the `tow hawser with the said brackets, a loop formed at the end of the towing line, a detachable shackle adapted to engage into said loop for connecting the towing line to the crow foot member and an inp termediate cable adapted to connect said loop to the tow hawser.

In testimony whereof we have signed our names to this specification.
