Abstract

Apparatus for handling a fishing line 15 having hooks 16 spaced apart along it, such as is used in "long line" fishing, when the line is hauled in from the sea, comprises a rail-member 24, a sheave 14 for hauling the line in a direction at an angle to the rail- member 24 and a guide-member 13 which is engaged by successive hooks of the line as it is hauled, to guide the hooks into engagement with the rail- member, whereby the movement of the line at an angle to the rail-member causes the hooks to slide along the rail-member 24 so as to separate them from the line and feed them towards a storage rail 53. <IMAGE>

Description

SPECIFICATION Apparatus for use in fishing This invention relates to apparatus for use in "long line" fishing, that is to say fishing such as may be carried out with sea-going fishing vessels, using a line having hooks spaced apart along it.

Such fishing lines have the hooks attached to the main line by short trailing lengths of line called "snoods". Lines of this kind are used for catching white-fish such as cod, ling, ray, turbot, plaice and haddock.

The bait-material used when fishing for whitefish is usually cut-up pieces of mackerel or herring, and the bait-pieces have to be attached to the individual hooks. In my British Patent Specification No. 2016881, there are described a method and apparatus which make it possible for a fishing line of the above-mentioned kind to be baited in a continuous operation as it is paid out from the fishing vessel. The baited line may conveniently be paid out from the stern of the vessel as the vessel moves forward, the distal end of the line being anchored to the seabed by means of a suitable anchor.

Subsequently the line with the catch thereon has to be taken up from the seabed. This is done with the distal end of the line still anchored on the seabed, and with the vessel moving forward towards the anchor-point and hauling in the line as it goes. As the line is hauled in, the fish may be removed from the hooks and the hooks cleaned, before feeding the line to a magazine for storage prior to a further fishing operation.

in conjunction with the baiting apparatus, in my aforesaid patent specification there is also described a particularly effective storage arrangement for fishing lines of the abovementioned kind, in which the hooks are engaged with a rail, so that the snoods hang down below the hooks, in closely spaced side-by-side relationship, and the main line is suspended from the snoods in looped formation. This arrangement minimises the possibility of tangling during storage, and ensures that when the line is required for further use, it can be fed to the baiting apparatus in an orderly and trouble-free manner.

When a fishing line which has been hauled in from the sea is fed to such an arrangement, the snoods carrying the respective hooks have to be unravelled from the main line and the individual hooks have to be separated and engaged with the rail, this operation being referred to as "splitting".

If carried out manually, splitting is an extremely tedious and time-consuming operation. The present invention is therefore particularly concerned with the provision of apparatus by means of which the operation of splitting can be carried out mechanically.

Accordingly the invention provides apparatus for separating hooks of a fishing line of the kind which comprises a main line having hooks spaced apart along the main line and connected thereto by snoods, the apparatus comprising a railmember, means for hauling a fishing line in a direction extending at an angle to the rail-member and a guide-member adapted to be engaged by successive hooks of such a fishing line being hauled by the hauling means, and to guide the hooks into engagement with the rail-member, whereby as the fishing line is hauled relatively to the rail-member, hooks engaged with the railmember are caused to slide along the latter so as to separate them from the main line.

As the fishing line is hauled, due to the fact that it is moving in a direction extending at an angle to the rail-member, as the individual hooks slide along the rail-member, they move away from the main line, the snoods which attach the hooks to the main line meanwhile executing a pivotting movement relatively to the main line, and in this way the separating or "splitting" action is effected in a continuous operation.

While the arrangement is such that at the point where the hooks are brought into engagement with the rail-member, the line is moving in a direction extending at an angle to the rail-member, preferably the rail-member is itself curved in such a way that sliding movement of the hooks along it, causes the snoods to pivot into a position in which finally they extend substantially perpendicular to the direction of movement of the main line, so as to complete the splitting operation.

The guide-member may conveniently be of generally tubular form, so that a fishing line passes through the guide-member as the hooks are guided into engagement with the rail-member.

Preferably the guide-member is in the form of a tube which is split lengthwise thereof and is arranged with its longitudinal axis extending at an angle to the rail-member so that a fishing line being hauled by the hauling means passes through the tubular guide-member in the direction of the said longitudinal axis thereof. The split tubular guide-member may define at one end face thereof, a slot extending radially relatively to the said end face, one edge of the slot being contiguous with the rail-member, whereby the slot serves to guide successive hooks of a fishing line passing through the guide-member, into engagement with the rail member A spring-loaded plunger may be provided in the slot, to control entry of successive hooks into the slot.

The guide-member and the rail-member together constitute the splitting device proper, and they may conveniently be of unitary construction.

The line-hauling means may conveniently comprise a drive-sheave rotated by a hydraulic motor and as will be seen from the more detailed description given hereinafter, the whole apparatus including the hydraulically operated line-hauling means and the splitting device can be constructed as a compact self-contained unit. For ease of cleaning, it is desirable for as many as possible of the components of the apparatus (and in particular the guide-member and rail-member constituting the splitting device as referred to above) to be made from stainless steel.

The invention will now be more fully described, by way of example only, with reference to the accompanying drawings. In the drawings: Figure 1 is a general view of one form of hauling and splitting unit, viewed in side elevation; Figure 2 is a fragmentary cross-sectional view on the line A-A of Fig. 1, drawn to a larger scale so as to show a detail; Figure 3 is a fragmentary view showing the splitting device which forms part of the apparatus of Fig. 1, drawn to a larger scale; Figure 4 shows the device of Fig. 3 in perspective view, as seen from the rear (i.e. the side which is obscured in Fig. 1); Figure 5 is a view corresponding to Fig. 1 but showing a modified form of hauling and splitting unit, in side elevation;; Figure 6 is a fragmentary plan view in the direction of the arrow B in Fig. 5, showing the device which can be seen at the right-hand end of Fig. 5 and drawn to a slightly larger scale; Figure 7 is a fragmentary view showing the splitting device which forms part of the apparatus in Fig. 5 viewed from the rear (i.e. from the side which is obscured in Fig. 5).

Referring to Fig. 1 , the apparatus shown therein serves for hauling a fishing line in from the sea. As the line is hauled inboard, fish are stripped from the hooks before the hooks reach the apparatus shown in Fig. 1.

The component parts of the hauling and splitting unit are carried by a mounting panel 10 supported by uprights 11, 1 2. The components mounted on the panel 10 include splitting device 13 and hydraulically driven line-hauling sheave 14. The sheave 14 draws the fishing line incoming from the sea through the apparatus in a generally horizontal direction. As previously described, the fishing line comprises a main line 1 5 having hooks 1 6 spaced apart along it and attached thereto by snoods 17. So that it can be clearly distinguished, the main line 1 5 is indicated in Fig. 1 by a dash-line.

After the fish have been stripped from the hooks and before reaching the splitting device 13, the line incoming from the sea passes by way of a device 1 8 which ensures that the snoods and hooks are properly aligned before being presented to the splitting device. The device 1 8 comprises a conical funnel-member arranged with its axis horizontal. The line passes axially through the member 1 8, entering by way of the larger diameter end and emerging by way of the smaller diameter end. As it enters the larger diameter end of the funnel-member 1 8, the line 1 5 bears against a transverse guide roller 1 9 which ensures that the line entering the funnel-member is correctly aligned relatively to the axis thereof.The pulling action exerted on the line 1 5 to draw it through the funnel-member 18 ensures that the funnel-member is effective to unravel any twisted snoods and to align the snoods 1 7 and hooks 16 correctly in relation to the main line 15.

A high-pressure water-pump (not shown) supplies water to the interior of the funnelmember 18 by way of a hose 21, in the form of high-pressure jets which serve to clean the line and the hooks as they are drawn through the funnel-member. Used water is discharged from the funnel-member by way of outlet 22.

The splitting device 1 3 includes a guidemember 23 of part-tubular form through which the line 1 5 passes in the direction of the longitudinal axis thereof. A rail-member 24 is mounted to extend upwardly away from the generally horizontal path of the line 15, at an angle thereto. The line 1 5 is drawn forward by the action of the hydraulically driven sheave 14 and the hooks 1 6 are fed to the rail 24 by the guidemember 23 which is located at the leading end of the rail 24, where the hooks are presented to the rail. Forward movement of the line causes the individual hooks 1 6 to be pulled along the rail 24 in a sliding movement.Due to the fact that the rail is inclined upwardly away from the main line 1 5, the hooks 1 6 are pulled upwards away from the main line, with the snoods 17 fully extended. A brush-member 26 is arranged with its bristles engaging the rail 24, the bristles serving to control the sliding movement of the hooks 1 6 along the rail 24.

As can be seen in Fig. 1, as well as extending at an angle to the direction of movement of the main line 15, the rail 24 is gently curved. The rail 24 is constituted by a stainless steel tube bent into the required curved formation and having a slot 25 (Fig. 2) extending lengthwise of the tube at the outside of the curve.

As can be seen from Figs. 3 and 4, guidemember 23 is welded to the end of rail 24 so as to be unitary therewith. Guide member 23 is formed by bending a plate into the form of a tube split lengthwise thereof. The bent plate is shaped to provide a short tubular entry portion 31 arranged with its axis horizontal, so that the main line 1 5 can pass axially through the said entry portion. In bending the part of the plate which forms the entry portion 31, the edges of the said part of the plate are brought together so as to co-operate with one another to define a horizontally extending slot 32 to receive hooks presented thereto. Individual hooks 1 6 enter the slot 32 under the control of a spring-loaded plunger.This is constituted by a rod 33, and a bore 34 is formed in the plate to provide a mounting in which the rod 33 is engaged so as to be slidable endwise under the action of a biassing spring 35, with an endportion of the rod being slidable into and out of the said slot 32.

The end face 36 of guide-member 23 which forms the rim of entry portion 31 extends in a plane which is inclined relatively to the longitudinal axis of the tubular guide-member and thus is generally elliptical. The slot 32 extends radially of the end face 36 and one edge 32a thereof is contiguous with the edge 24a of rail 24.

As previously mentioned, the line being hauled in from the sea is drawn in a substantially horizontal direction through the entry portion 31 of the guide-member 23. The individual snoods 1 7 are drawn into the entry portion 31 with the main line 15, and the hook 1 6 carried by each snood is thus drawn into engagement with the elliptical rim or end-face 36 of the tubular entry portion 31, with the shank of the hook 1 6 inside the entry portion 31 and with the barbed end of the hook located externally of the entry portion 31. The hook 16 then slides circumferentially around the elliptical rim 36, towards the slot 32.

At a position diametrically opposite the slot 32, there projects a fin-like member 37 having a razorsharp edge. Any hook which comes into contact with this fin-like member 37 is deflected sharply to one side or the other and then slides towards the slot 32. Thus there is no risk of the hooks becoming snagged. Since the plane in which the rim 36 lies is inclined relatively to the axis of the entry portion 31 (in the direction away from the fin-like member 37), this assists the sliding movement of the individual hooks towards the slot 32.

As each hook 1 6 reaches the slot 32, it finds the slot closed by the plunger 33. However the pull on th'e hook is sufficient to overcome the action of the biassing spring 35. Thus the hook slides into and along the slot, under the control of the spring-loaded plunger 33.

The rim 36, the edge 32a of slot 32 and the edge 24a of rail 24 extend contiguously so as to provide a continuous guide-edge to lead hooks to the rail 24. As previously mentioned, as each hook slides around the rim 36, its barb is located externally of the tubular entry portion 31 and in this position, it moves into the slot 32 in the entry portion 31. However, after sliding around the rim 36, passing through the slot 32 and entering the slot 25 of the rail 24, the barb will now be located internally of the slot 25.

As the line is drawn through the guide-member 23 in the manner described above, each snood 1 7 on the line is drawn in turn into the entry portion 31 and its hook is pulled into engagement with the rim 36 of the entry portion 31 and thence into mouth of the slot 32 in the latter. The hook is momentarily arrested by the plunger 33, which is in the position in which it closes the slot 32.

However, as the line continues to move forward, the snood 1 7 is tensioned and exerts a pulling action on the hook 16, so that the plunger 33 is displaced against the action of its biassing spring 35 and the hook can enter the slot 32. This ensures that the hook 1 6 enters the slot 32 in the correct alignment and it then slides into engagement with the guide-edge 24a of the rail 24 and thence into the slot 25 in the rail 24.

Meanwhile the plunger 33 returns to the position in which it closes the slot 32 so that the device is ready to receive the next hook.

As already mentioned, as each hook enters the slot 25 in the rail 24, its barb is now located internally of the slt 25 and in this position it slides along the slot 25 with its barb engaged inside the latter. For this purpose it has been found advantageous for the slot 25 in the rail to be formed in such a manner that as indicated in Fig. 2, the plane of the slot is not precisely radial, but subtends an acute angle or (say 250) relatively to the radial plane. This ensures that the hooks 1 6 are retained effectively in engagement with the rail 24 and slide along it in a trouble-free manner.

As previously mentioned, the line is drawn forward through the apparatus by hauling means including the hydraulically driven sheave 14, which is driven in contact with the main line 15.

Sheave 14 is driven by a hydraulic motor which is mounted behind the panel 10 (Fig. 1) and thus is not visible in the drawings. A control valve is provided for adjusting the operating speed of the hydraulic motor, so as to enable the line-hauling speed to be varied. Effective driving of the line is ensured by a counter-wheel constituted by a nylon disc 41 mounted on a spring-loaded lever-arm 42.

A handle 43 is provided by means of which the disc 41 can be disengaged from the sheave 14 when required. Normally, however, the disc 41 bears against the main line under spring-pressure and holds it in driving engagement with the sheave 1 4.

Mounting means (not shown in detail in the drawings) are provided, so that a detachable magazine 50 can be clipped in position in the apparatus and withdrawn when a line has been fed into it. The magazine includes a basket-portion 51 made of stainless steel wire-mesh, with an - upright 52 extending from basket-portion 51 and supporting a horizontal rail-member 53. When the magazine is inserted into position, rail-member 53 comes into end-to-end engagement with the curved rail 24 of the splitting device 13, so that the curved rail 24 then leads from the splitter to the rail-member 53 of the magazine. As already mentioned, forward movement of the main line 1 5 pulls the hooks 1 6 one by one along the curved rail 24 and they then slide into engagement with the rail-member 53 of the magazine.However, beyond the drive-sheave 14, the main line 1 5 simply drops into the basket-portion 51 of the magazine and the line 1 5 no longer acts to pull the hooks 1 6 forward. It is therefore necessary to provide means for positively driving the hooks 1 6 along the rail-member 53 of the magazine. Such means include a circulating belt 54 passing around two pulleys 55, 56 which are rotatable about horizontal axes above the rail-member 53 of the magazine, with one run of the belt 54 positioned immediately above the rail-member 53.

Pads or flaps 57 of rubber or plastics material are secured at intervals along the belt 54. One of the pulleys 55, 56 is driven by means of a belt transmission, from the same hydraulic motor as drives the line-hauling sleeve 14.

As the belt 54 circulates, the flaps 57 engage the individual hooks 16, as they slide into engagement with the rail-member 53 of the magazine, and propel them along the rail-member 53, towards the far end of the rail-member 53, that is to say, the lefthand end as viewed in Fig. 1.

As each hook 1 6 is propelled along the railmember 53 in this way, it carries its associated snood 1 7 with it, thus ensuring that the main line 1 5 is packed into the magazine, commencing at the far end (i.e. the lefthand end in Fig. 1) of the basket-portion 51. The hooks come to rest sideby-side on the rail-member 53, with their snoods hanging down below them, so that rail-member 53 serves as a hook-store.

After a full magazine is removed from the apparatus, the hooks are inspected and any damaged hooks are transferred from the railmember 53 to a further rail-member 58 mounted below the rail-member 53, so that they are readily accessible for repair. When the line is subsequently drawn out of the magazine during baiting, the repaired hooks are pulled out so that there is no possibility of tangling.

Referring now to Fig. 5, the overall arrangement of the modified form of hauling and stripping unit shown therein is generally similar to that shown in Fig. 1. The component parts of the apparatus are carried by a mointing panel 110, which in this case is supported in a somewhat inclined position on uprights 111 and 112. In a similar manner to the unit shown in Fig. 1, the panel 110 supports hydraulically driven sheave 114 and co-operating disc 141 by means of which the line is hauled in.

However, the unit shown in Fig. 5 is intended to be installed on a boat with the panel 110 extending in the fore-and-aft direction (rather than across the boat). The line is hauled in from the sea over the side of the boat and therefore has to be deflected through 900 before it reaches the splitting device 11 3. For this purpose, after the fish have been stripped from the hooks, the line passes through a device 120 consisting of a long tubular member or pipe 118 extending from a box-like mounting portion 11 8a and having a conical mouth or funnel-portion 11 sub. A pulley 119 is freely rotatable in the portion 11 spa on a spindle 11 9a and the incoming line is hauled around the pulley so as to deflect it through 900 as required.The device 1 20 is carried by a bracket 1 20a which is mounted for pivoting movement about a horizontal axis. This enables the device 120 to be swivelled upwards and downwards through a limited arc, so as to adjust the angle of the pipe 11 8 relatively to the horizontal. Water under pressure is supplied to the device 1 20 by way of hose 121 so as to provide a high-pressure jet of water passing through the pipe 11 8, to clean the line and the hooks as they are drawn through the pipe. Water is ejected from the funnel-portion 11 sub and the angular position of the device 120 is adjusted by swivelling it upwards or downwards as referred to above, so that the jet of water is discharged over the side of the boat.

After passing around the pulley 11 9, the line reaches the splitting device 11 3 which comprises guide-member 123 and rail-member 124. The rail-member 124 is of similar construction to that shown in Fig. 1 but the guide-member 123 is somewhat modified. As shown in Fig. 7, guidemember 123 has a tubular entry portion 131 presenting an elliptical rim 136, and a fin-member 1 37 projects radially relatively to the rim 1 36.

However, the semi-cylindrical upper part 127 of the tubular entry-portion 1 31 is made separate from the remainder of guide-member 123 and is hingedly mounted by means of a hinge 128. A lever which is not fully visible in Fig. 7 projects from the hinge 128, at 129. A coil spring 130 is connected between the lever and a lug 1 37a carried by fin-member 1 37. The spring-pressure applied to the lever normally urges part 127 into the closed position shown in Fig. 7, in which part 1 27 co-operates with the remainder of the guidemember 123, to define slot 132.During linehauling, if a knot or tangle is encountered, which cannot pass through entry-portion 131, the above-mentioned lever is pivotted by hand, against the pressure of the spring 130, so that the part 1 27 pivots about hinge 128, in the direction of the arrow C in Fig. 7, thus opening up the slot 132 and allowing the knot or tangle to pass.

A plunger-rod 133 projects into the slot 132.

At its opposite end, the plunger-rod 133 has a head 1 38 and spring-pressure is applied to head 1 38 by means of a tension-spring 135. The spring 1 35 is mounted inside two interfitting tubular parts 144 and 145, the part 144 being welded to the guide-member 123 and the part 145 carrying a lug 146 by means of which spring pressure is applied to the plunger-head 138, thus urging the plunger 1 33 into its operative position in the slot 132.

In a similar manner to that described with reference to Fig. 1 , the plunger 1 33 controls the movement of successive hooks 1 6 through the slot 1 32 and into engagement with the rail 124.

The hooks then slide along the rail towards the magazine 1 50.

The arrangement of the magazine 1 50 is similar to that described with reference to Fig. 1.

However, because of the inclined disposition of the mounting panel 110, the magazine is mounted with its rail-member 1 53 inclined, which assists sliding movement of the hooks along the latter under the action of the flaps 1 57 on circulating belt 1 54.

If desired, the circulating belt arrangement could be dispensed with and, instead, a nozzle could be mounted on the panel 110, directing a water-jet in the direction of arrow D, so as to push the hooks along rail-member 1 53. Water would be supplied to the nozzle under pressure via a hose.

This water-jet arrangement could also be applied to the embodiment of Figs. 1 to 4.
